Scientists should be skeptics. Science is always based on the evidence. Is there evidence supporting climate change? How long are the trends based? Is there evidence that this is a normal cycle? Give me two pieces of evidence from the Fire and Ice Section that supports climate change. How much has the global average sea level risen since 1993. How much warmer is Fairbanks Alaska than 100 years ago? How much has carbon dioxide increased per year? What percent of Alpine glaciers has Europe lost? Read the article below and answer the questions and tell me your thoughts on the subject. Think like a scientist.
Climate Change or something just like it

Sea ice thickness has decreased by 43% between the 1970s and the 1990s. The overall volume of glaciers in Switzerland has decreased by two-thirds. It has rasen 17 cenimeters scince
1993. Fairbanks alaska is 2.5F hotter.2 million tons per a year. Europe has lost 50% of there apline glaciers.
Yes there is evidence supporting climate change.The last 50 yeaars or so. No there is no evidence this is a normal cycle.The sea thickness has decreased by 43%.Greenland lost 250 cubbic meters of ice.It has rise 17 centimeters. It is 2.5 degrees warmer.Incresed by 2 billion tons per year. It has 50 % of glacier.

Ted in the comments it said that it was part of the normal cycle.
Yes there is evidence of climate change.Thesetrends are based upon 50 years, but there is not evidence that this is a natural cycle, since the climate has changed this year and there is no evidence that relates in the past.
Fire and Ice- The volume of Switerland glaciers have decreased by 2/3. Also in 2008 the N. Pole became an island for the first time.
Since 1993 the global sea level has risen 3.5 mm/annually per year.
Fairbanks Alaska is 2.5 degrees fehreinheit warmer than 100 years ago.
Carbon dioxide increaased 2 billion tons per year.
Europe has lost 50% of the Alpine Glaciers.
the ea ice thickness decreased 43 percent between 1970s and the 1990s.Global sea level rose about 17 centimeters 6.7 inches in the last century but the rate in just the last decade is nearly double that of the last century. Global means sea level has risen 3.5 mm year annually 1993. Green land lost up to about 250 cubic kilometers of ice annually 2002 2006
Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer 11 percent drier than 100 years ago carbon increased by 30 percent 20 percent of there in Switzerland
i agree with Anthony all his in of is some what correct
Shanen i didnt think that global means sea level has risen. By ted young
there is evidence supporting climate change. these are based hundreds of years ago to now. there is evidence that this is not a normal cycle. Sea ice thickness decreased 43% between the 1970s and the 1990s. The Arctic’s 2011 maximum sea ice coverage (which occurred on March 7th) is tied with 2006 for the lowest recorded annual maximum. Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer & 11% drier than 100 years ago. The carbon dioxide content of the Earth’s oceans is currently increasing about 2 billion tons per year. Ocean acidity has consequently increased by about 30 percent.
YAHANZ VELASQUEZ
Yes there is evidence supporting climate change.
Trends are based by 50 years.
No there is no evidence that supports that there is a normal cycle.
One piece of evidence is that the Glacier National Park had 150 glaciers in 1850 but now there is only 25 glaciers left.Another peice of evidence is that the sea ice thickness decreased 43% between 1970s and 1990s.
The global average sea level has risen about 3.5 mm since 1993.
Fairbanks Alaska has gotten 2.5 degrees Fahrenheit.
Carbon dioxide has increased by 2 billions tons per year.
Europe has lost 50% of its Alpine glaciers.
Anthony- Do you think this has to do with global warming? Since the earth's climate has never beeen like this. If not what do you think itr has to do with?
Sydney Kilgore And Madison Schnell.
Minnasota Averege temp. has risen almost 1 degree fahrenheit over the last decade. Decades. Sea ice thickness has decreased 43% between 1970s-1990s. The overall volume of glacirs in switzerland has decreased by two-thirds.17 centermeters. 2.5 degrees. 2 billion gallons.
yes. 50 years. no. Sea ice thickness decreased 43% between the 1970s and the 1990s.
Large wildfire activity increased dramatically in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons. 3.5 milimeters. 2.5 degrees warmer. 2billion tons. 50%.

@ Sydney:
You can see the effects of climate change for recent time(about from 100 years ago and now).
What do you think will happen in the next 100 years?
yes their is evidence supporting climate change ,the trends based are 50 years or more ,one of the evedence from the fire and ice section is ,Sea ice thickness decreased 43% between the 1970s and the 1990s ,another one is The overall volume of glaciers in Switzerland has decreased by two-thirds. Global mean sea level has risen 3.5 mm/year. fairbanks, alaska Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer & 11% drier than 100 years ago. The carbon dioxide content of the Earth’s oceans is currently increasing about 2 billion tons per year.Europe has lost 50% of its alpine glacier ice in the last century. i think that earth was way warmer 100 years ago then todays weather just think if it was burning hot just like 100 years ago.
Yes ther is evidence opf climaste changer. trends based on recent times. yes ther is evidence tghta it is part of a normal cycle. sea ice thickness has by 43% between the 1970 and 2990. the overal volume of glaciers in switzerland has gone down by 2/3, it rised 17 cenimeters since 1993. fairbanks alaska is 2.5F hotter. 2million tons per year. europe has lkost 50 percentof the glaciers
Brendan mcwilliams
I agree with ted it is 2.5 degrees warmer incresed by 2 billion tons per year. It has 50 % of glacier.
~Daniel O'Hearn~
wow tony i never knew that europe has lost 50% of there apline glaciers
I agree with yahanz I think it is not a normal cycle too.
There is factual information supporting the idea of climate change. The informations has started to change within the past 50 years or so. However, there is no information supporting that the climate change is natural. The thinkness of the ocean decreased by 43% within 20 years
.250 cubic meters of ice were melted from Greenland. In Switzerland, the glacier have decreased by 2/3. In Fairbanks, Alaska the average degees has gotten 2.5 degrees warmer. Lastly, carbon dioxide has increased by about 2 tons per year.
Yes, i do think that there is alot of evidence. There is also evidence that this is normal. In 1850, Glacier National Park had 150 glaciers, now there are only 26. and Sea ice thickness decreased 43% between the 1970s and the 1990s.
Fairbank alaska is 2.5 degrees warmer. About 2 million tons of carbon dioxide per year.
Yes there is evidence supporting climate change.These trends are based upon 50 years or so.There is no evidence that this is a normal cycle. Since the climate has changed this year, there is no evidence that relates in the past.

Yes there is evidence supporting Climate Change. This evidence is very recent, in about the last 200 years. I honestly think there is no evidence supporting a natural cycle, the changes have been too recent and have very little time in between. Natural cycles take thousands of years, not a few decades.
Supporting Claims of Climate Change
1.)In 1850, Glacier National Park had 150 glaciers. Today there are 26.
2.)Annual blooms of phytoplankton — tiny plants and algae critical the Arctic food chain — are now peaking up to 50 days earlier than they did 14 years ago, due to melting ice cover.
The sea level rose about 17 cm.
Fairbanks, Alaska is now 2n5 degrees warmer.
The level of CO2 is increasing by 2 billion tons per year. No wonder we have Global Warming.
The overall ice coverage decreased by 2/3. Greenland lost 250 cubic km. Glacier National Park lost 124 glaciers in the past 150 years.
I honestly blame us and our livestock, everyday we send CO2 into the air, 10000 years ago, before the invention of AUTOMOBILES, LAWNMOWERS, POWER PLANTS, and just our CURRENT TECH, things were normal, climate change USED to be a cycle, everyday before late 1950 never passed a line, now its WAY up above it!You might want to check out this link to understand. http://climate.nasa.gov/evidence/
The Graph shows how CO2 levels are rising dramatically. So in order to get rid of the spare ozone and CO2 levels we need to:
A.) Plant more trees to make more oxygen
B.) Have everyone in the world not drive a coar for at least 100 years, find new fuels and different ways to power our home and vehicles differently (Such as wind, hydroelectric, ect.)
C.) Flood the world and have everyone buy a private gondola or man powered boat, just like Venice, Italy.
D.) Keep this up and have polluted air.
Try to post to this and to see a head count of the best way, I honestly think A or B is (are) best

yes there is alot of evidence that the climate is changeing. the trends are based on recent times.yes there is some eveidence that there a normal cycle.In 1850, Glacier National Park had 150 glaciers. Today there are 26.
this is because of the glaciers melting from global warming.Sea ice thickness decreased 43% between the 1970s and the 1990s.
this is because glaciers melting and becomeing ocean water.Global sea level rose about 17 centimeters in the last century.Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer than 100 years ago.Carbon dioxide is currently increasing about 2 billion tons per year.

-Corissa Sturm,(:
Anthony Papathanas i agree with all of your information
Yes there is some evidence of climate change. Trends are based on recent times (over 50 years). Yes there is evidence that this is part of are normal cycle.
Fire and Ice-
(1.)Glacier Park had 150 glaciers and today there are 26. Since the ice ages stopped 10,000 years ago, there have been many slight climate shifts causing periods of glacier growth or melt-back.
(2.)If the current warming trend continues in Glacier National Park, there will be no glaciers left here in the year 2020.
The global average sea level has risen 3.5 mm/year annually since 1993.
Fairbanks Alaska is 2.5 degrees Fahrenheit warmer & 11% drier than 100 years ago.
The carbon dioxide content of the Earth is currently increasing about 2 billion tons per year.
Europe has lost 50% of the Alpine Glaciers.
I agree with Anthony Papathanas.That was a lot of apline glaciers that europe lost but I wonder if it could affect other things like population.
Ted i thought it was a part of a normal cycle
Yes there is evidence supporting climate change.
Trends are based by 50 years.
No there is no evidence that supports that there is a normal cycle.
Fire and Ice- The volume of Switerland glaciers have decreased by 2/3. Also in 2008 the N. Pole became an island for the first time.

Do you think that global warming could be completley gone if we tried hard enough ?
-Corissa Sturm,(:
@ Anthony
Do you think this has to do with global warming? Since the earth's climate has never beeen like this. If not what do you think it has to do with?
Yes, as matter of fact, there was some evidence of climate change. Trends tend to be based on recent times, but yeah, there is evidence that this is part of our normal cycle. The sea ice thickness has decreased by 43% between 1970 and 1990. But,however, the overall volume of glaciers in Switzerland has decreased by 2/3. Fairbanks, Alaska is 2.5 feet hotter. 2 million tons per year. Europe has lost about half of their Alpine glaciers.
@ Kaleb
I didn't know the glaciers in Switzerland decreased by 17 centimeters.
There is evidence supporting climate change. The trends are based mostly from 50 years ago, but go back to 1850. Some evidence shown from 2008 is that the North Pole, for the first time in history became an island. This is supported by satelite images show that open water surrounded the arctic. This made it possible to circumnavigate the North pole for the first time in history. More evidence shows that glaciers in switzerland have melted by 2/3. Grennland lost 250 cubic kilometers annually from 2002 to 2006, which even further shows global warming. Evidence shows that the global mean sea level has risen 3.5mm/ year annually since the year of 1993. Fairbanks, Alaska is 2.5 degrees warmer, and 11% drier. Amount of carbon dioxide is increasing by 2 tons each year, making the oceans 30% more acidic. In Europe, overall has lost 50% of its alpine glaciers in the last century.

Ben;
The gobal average sea level has risen 3.5mm/year since 1993, not 17 centimeters.
Marissa&Chase
The trends are based on the last 50years or so. The evidence is what the people see, record, photograph,count and pass information from genoration to genoration. from the fire and ice artical In 1850 there were 150 glaciers and today there are 26 left. now there are 25 because of the climate change. the sea average increased by 43% from 1970 to 1990. no evidence of a normal cycle. alaska is 2.5 degrees fernhight warmer.the carbon dioxide increased 2 billion tons. the alpines lost 50% of glaciers.
Yes there is evidence supporting climate change.The trends are based 50 years,But its not a proven cycle.
Fire and Ice
The overall volume of glaciers in Switzerland has decreased by 2/3.
Sea ice thickness decreased 43% between the 1970's and the 1990's.

@Ted Young,
We found that it was part of a normal cycle, unlike what you have said.
-Michael Van Schoik and Sam Tendam
wow! michael i didn't know that there was evidence from 2008 that the north plone was conciterd an island! i think thats weird because when you think of an island you find them to be warm instead of colder. thats really intersesting i hope we learn more about that!
Trends are based on 100000 years ago there is evidence that this is a, normal cycle. Sea ice thickness has decreased by 43% in the 1970 and the 1990
I agree with you Michael your info is correct.
yes there is evidence of climate change. The trends ranges from around 50 years ago. There is no evidence that it is a normal cycle. In the year of 1850 Glacier national park had 150 glaciers. Now there are only 26. Between the years of 1970s and 1990s sea ice thickness decreased 43%. the average sea level raises 3.5 mm a year since 1993.Alaska iis 2.5degrees fahrenheit warmer and 11% Drier.Carbon dioxide has increased 2 billion tons per year. Europe has lost 40% of alpine glaciers.
hunter steimle
i agree with sydney there are climate changes over 50 yearsw
BEn the average sea level has risen 3.5 mm per year not 17 centimeters. hunter steimle
yes. the last 50 years. the Arctic’s 2011 maximum sea ice coverage is tied with 2006 for the lowest recorded annual maximum. Greenland lost up to 250 cubic kilometers of ice annually between 2002 and 2006; Antarctica lost about 152 cubic kilometers of ice between 2002 and 2005. 17 cm. 3.5 mm per year. 2.5 degrees warmer.50%.
there is evidence in climate change. glaciers are melting and the ice is melting. ice thickness has decreased by 43% between 1970 and the 1990s.
taylor roberts
There is evidence that the climate is changing and it is changing fast. The trends are based on the past 50 years. This is not a natrual cycle of the earth. Glacier National Park had over 150 glaciers and now the park anly has 26 glaciers left today, and the arcitic ice thickness has decreased by 43% between the 1970s and the 1990s. The global sea level has risin adout 17 centimeters. Fairbanks is 2.5 degrees warmer and 11% drier. The carbon dioxide has increased by 2 billion tons per year. Over all europe has lost 50% of its glaciers. I think that we are in a lot of trouble if we don't do something about this.
I would say yes that there are some evidence of climate change. These trends are usually based on recent times. And I think that the climate change IS a normal part of our cycle. Here is some proof: In 1850, Glacier National Park had about 150 glaciers. Today, GNP (Glacier National Park) has only 26 glaciers left. Sea ice thickness has decreased in between the 1970's
and the 1990's. Global sea level rose about 6.7 inches (17 centimeters). Fairbanks, Alaska has warmed about 2.5 degrees Farenheit and is about 11% drier.
Europe has lost about half of their alpine glaciers.
Yes, there is evidence of change. Trends on based on recent times. There is evidence of a normal cycle. In 1850,Glacier National Park had 150 glaciers, today there is now 25 glaciers. The sea ice thickness decreased by 43% between 1970s and thw 1990s. The global average sea level has risen about 17 centimeters (6.7 inches). Fairbanks, Alaska got 2.5 fahrenhiet warmer. Carbon dioxide has increased by 2 million tons a year. Europe has lost 50% of its alpine glaciers.
Jordan Malsbary and Abby Bacher:
I didn't know that Switzerland has lost 2/3 of their glaciers. If you think about that, that actually sounds kind of scary. Just think about it.
Yes there is evidence of climate change. Mostly 50 yrs. No, because greenland has lost 60 cubic meters of glacers and the heat has made more than six times more land. 17 cm. Fairbanks is 11% warmer. 2 billion tons per year. 40% has been lost.
I agree with Eathan on how wildfires have increeses science the 1980's and up. Also on the persent of Glacers melting.
Alex Richmond
There is some evidence in climate change. Evidence is also part of a cycle. Ice thickness has decreased by 43% between 1970 and 1990. Greenland lost 250 cubic meters. It has rasen 17 cm since 1993. Fairbanks alaska is 2.5F hotter. 2 million tons a year. Europe has lost 50% of there apline glaciers.
Yes there is evidence of climate change. trends based on recent times. yes theree is evidence that it is part of a normal cycle. sea ice thickness has by 43% between the 1970 and 2990. the overal volume of glaciers in switzerland has gone down by 2/3, it rised 17 cenimeters since 1993. fairbanks alaska is 2.5F hotter. 2 million tons per year. europe has lost 50 percent of the glaciers
~Kristin Murphy (:
There is definitely evidence that the climate is changing.The trends are based on millions of years ago to today.There isn't evidence that its normal thats why its such a big deal.Over this period, the sea-ice extent over the Northern Hemisphere showed a decrease of -2.8 ± 0.3%/decade.Fairbanks alaska is 2.5 hotter.Europe has lost 50% of there apline glaciers.
yes....there is evidence of climate change. Evience is all over the USA. The trends are based over 50 years. there is no evidence that this is a normal cycle. Sea ice thickness has decreased by 43% between the 1970s and the 1990s. 250 cubic meters of ice were melted from Greenland. In Switzerland, the glacier have decreased by 2/3. In Fairbanks, Alaska the average degees has gotten 2.5 degrees warmer. Lastly, carbon dioxide has increased by about 2 tons per year.
Yes there is evidence of a climate change. The trends are based on the past 50 years. This is part of a normal cycle. Evidence that supports this is the fact that wild fires increased dramatically in the mid 1980's due to high tempatures. The fires were longer and lasted for a long time. Also, the over all volume of glaciers in Switzerland has decreased by two thirds. The global sea level average since 1993 has raised 17 centimeters. Fairbanks, Alaska is 2.5 degrees warmer than 100 years ago (1911). Carbon dioxide increased by about 2 billion tons a year. Overall, Europe has lost 50% of its glaciers. I'm still not sure if there's global warming. Even though this evidence supports that there could be, I think this could all just be a minor climate change and things could go back to the way they were. But seeing how much earth has changed over the years, that's probably not going to happen.
Yes there is evedince of Climate change these trends have been based for about 50 years. No these are not natural causes.
Global mean sea level has risen 3.5 mm/y ever since 1993.
Fairbanks Alaska is 11% drier and 2.5 degrees warmer than it was 100 years ago.
About 2 million tons per year
It has decreased by about 2/3rds(Volume in Switzerland)
My thoughts are, this is alot of carbon dioxide and also many glaciers are melting. Global warming is becoming a problem.
@Abby Jaspers
I agree that there is alot of evedince that whole website is full of evedince supporting changes in climate.
To Anthony: I agree with all of your evidence. You supported your facts good to.
There is evidence supporting climate change. The trends are based upon 50 years. There is not evidence that this is a normal cycle, because our climate isn't the "ideal" climate. It has been changing recently.Evidence from Fire and Ice includes:
-The volume of Switerland glaciers have decreased by 2/3.
-In 2008 the North Pole became an island for the first time.
-Global sea level has risen 3.5 mm/annually per year since 1993.
-Fairbanks Alaska is 2.5 degrees warmer than 100 years ago.
-Carbon dioxide has increased 2 billion tons per year.
-Europe has lost 50% of the Alpine Glaciers.
Yes there is evidence of climate change.Thesetrends are based upon 50 years, but there is not evidence that this is a natural cycle, since the climate has changed this year and there is no evidence that relates in the past.
Fire and Ice- The volume of Switerland glaciers have decreased by 2/3. Also in 2008 the N. Pole became an island for the first time.
Since 1993 the global sea level has risen 3.5 mm/annually per year.
Fairbanks Alaska is 2.5 degrees fehreinheit warmer than 100 years ago.
Carbon dioxide increaased 2 billion tons per year.
Europe has lost 50% of the Alpine Glaciers.
I agree with ted it is 2.5 degrees warmer incresed by 2 billion tons per year. but the question i have about that is is that really a lot of change of that long of a time period
There is evidence of climate change in the last 50 years. there is no evidence that this is a normal cycle.Sea ice thickness has decreased by 43% between the late 1970s and the 1990s. the glaciers in Switzerland had decreced by two thirds.It has risen 17 cenimeters scince
1993.It is 2.5 degrees warmer there.It has incresed by 2 billion tons per year.
@ Ciarra
I think it is interesting how much our Earth is changing. I think we need to do something about it! If global warming continues at the rate it is now we will have a lot of animals dying and going extinct. We already have enough animals extinct. We don't need anymore. If we step in and stop global warming we will have a better planet.
One evidence of climate change is the Glacier National Park had 150 glaciers in their museum and now they only have 25 glaciers. The trends are based from the last 50 years ago. Yes because these are recently what people have been able to see. One piece of evidence is sea and ice thickness has decreased 43% between the 1970s and the 1990s. Another example is the overall volume of glaciersin Switzerland has decreased be two-thirds. The global sea level has risen 17 centimeters (6.7 inches). Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer and 11% more drier than 100 years ago. The carbon dixoide in the Earth is currently increasing about 2 million tons per year. Europw has lost 20% percent of its glacier ice.
-Dylan Humbert
Yes, there is evidence of climate change. Most trends are based on recent times. There is evidence showing this is part of the normal cycle. Sea Ice Thickness(SIT) has decreased by almost 43%, between the 1970's - 1990's. Volume in Switzerland has decreased by almost 2/3(66.6%). Its risen 17 centimeters from last time(1993). Alaska, is 2.5 degrees faronheit hotter. About 2 million tons per year. Lastly, Europe has lost almost 50% of the Apline Glaciers.
I agree with Sydney and Zac that there are changes over 50 years.
Yes there is evidence of climate change. These trends are based over many years. There is no evidence that this is a normal cycle. Sea ice thickness decreased 43% between the 1970s and the 1990s. Also the overall volume of glaciers in Switzerland has decreased by two-thirds. It rose 17cm. It is 2.5 degrease warmer. It increased 30%. They lost about 83% of the glaciers.
Yes. Trends were based 50 years. No. In 1850, Glasier National Park had 150 glasiers. Today there are 25. Sea ice thikness decreased 43 percent between the 1970s and the 1990s. Global mean sea level has risen 3.5 a year annually since 1993. It got warmer by 2.5 digrees. It increassed by 2 billion tons a year.
by: Gillian melugin
Yes there is evidence in climate change.Sea-ice extent is expected to become a sensitive indicator of a warming climate.The sea ice has decreased. The sea ice thickness decreased by 43%. There has been a lot of forrest fires just this year.
I agree with Anthony:
I agree with him because there is a couple pieces of evidence in Science. My question is, " How many glaciers have we lost over time altogether?"
I agree with you anthony
-Dylan Humbert
there is a definite climate change for sure. The trends are based for 50 years. We can tell that this is no evidence of a normal cycle because the climate is not repeating itself. A piece of evidence is shown because things are increasing and decreasing and not staying the same. The global sea level increased about 17centimeters. The degree F for Fairbanks Alaska increased by 2.5oF. Carbon dioxide has increased by 2billion tonnes. Alpine Europe has lost 50% of their glaciers.
Global warming is an example of climate change. The trends are based on 50 years. there isn't any evidence. about 2/3 of the glaciars in Glacier park have melted and antarctica became an island due to the melting of it's snow and ice. the level has rised 3.5 cm since 1993. Fairbanks, Alaska has gotten warmer than it was 100 years, the temp has risen by about 2 degrees ferinhite. carbon dixide has increased by 2 million tons per year. Eourope has lost about 50% of it's glaciers.
Ryan Bussard
@ Jenna Duebber:
I agree! If every thing keeps going the way it is, we will have lots of life dying. And we rely on that kind of stuff to survive.
I agree with Yahanz there is a lot of examples of how the climate change is not a normal cycle.
at Jenna
I agree that the volume of Switerland glaciers have decreased by 2/3.but it was more than that to.
@ Sara Dirr-
Yeah I think that this is becoming a problem. With the earth's climate getting as hot as it is, things are going to start dying! People need to do something about it. I definitely think that humans have something to do with it.
i agree with caleb huttson that this can turn into a big deal.
that is a good thought sydney kilgore! Mabye it does have something to do with the global warming
I agree with Jenna Duebber:
I wish we could be better about protecting our planet. WE should all be helping protect the animals and plants that are in need.
Large wildfire activity increased dramatically in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons. and
In 2008 the North Pole became an island for the first time in human history. Satellite images showed open water surrounding the Arctic, making it possible to circumnavigate the North Pole for the first time.
I agree with tony about that there is a change in climate
to: kalub Quinlin
yes i agree with you that global warming in recent years isn't true.
Ryan Bussard
yes the climate changes all the time. there is also evidence that this is a part of the cycle ice thickness has decreased 43% between 1970 and the 1990.
Yes there is evidence that it has gotten slightly warmer. They are based on recent years. There is evidence that it is part of the normal cycle. Ice thickness decreased by 43 percent from the 1970s and 1990s. The volume of glaciers in Switzerland have decreased by two thirds. It rose 17 centimeters since 1993. Fairbanks, Alaska is 2.5 degrees hotter. 2 million tons a year Europe lost half of their glaciers.
yes there is evidence of the climate changing. Every once in a while there would be big storms. then we would have a break beefore another storm comes.
Kristan Dalton
Yes there is evidence supporting climate change.These trends are based upon 50 years.There is no evidence that this is a normal cycle.Fire and Ice- The volume of Switerland glaciers have decreased by 2/3.

Fairbanks Alaska is 2.5 degrees fehreinheit warmer than 100 years ago.Carbon dioxide increaased 2 billion tons per year.
Europe has lost 50% of the Alpine Glaciers.
i agree with deborah how europe lost 50% of their glaciers. thats alot.
Anthony,Papathanas
I agree that the overall volume of glaciers in switzerland have decreased.
Kristan Dalton
Yes there is some evidence chang.Trends are based on recent times.There is evidence that this is part of are normal cylce. Sea ice thickness hasdecreased by 43% between the 1970's and 1990's.The overall volumne of glaciers in Switzerland has decreased bt two-thirds. it has risen 17cm scince 1993. Fairbanks Alaska is 2.5 degrees ferinhieght hotter.2 milliontons per year. Europe has lost 50% of there alpine glaciers.
Andrew Hudson
I agree with Anthony that Fairbanks Alaska is 2.5 degrees hotter.
Andrew Hudson
Yes there is evidence supporting climate change.
The trends are based for about 50 years.
No there is not evidence that it is a normal cycle.
Sea ice thickness decreased 43% between the 1970s and the 1990s.
In 2008 the North Pole became an island for the first time in human history. Satellite images showed open water surrounding the Arctic, making it possible to circumnavigate the North Pole for the first time.
The global average sea level has risen about 3.5 mm since 1993.
Fairbanks Alaska has gotten 2.5 degrees warmer.
Carbon dioxide increased by 2 billions tons per year.
Europe lost about 50% of its Alpine glaciers.
Yes there is evedence of climate change. Trends are based on 50 years. Their isnt any evidence that compares with the
Fire and ice section- The Himalayas have lost a third of their snow. Sea ice thickness decreased 43% between the 1970s and the 1990s. In 1850, Glacier National Park had 150 glaciers. Today there are 26!! It has risen 17 centimeters. 2.5 degrees F more. Europe has lost 50% of their alpine Glaciers.
There is some evidence of climate change. Trends are based on recent times. Yes there is evidence that this is a normal cycle. Sea ice decreased between the 1970s and the 1990s. In 2008 the North Pole became an island for the first time in human history. 17 centimeters. 2.5 degrees Fahrenheit. 2 billion tons. 50%.
@ Dylan Buis
Dylan what is 2/3 of its volume equal in tons.
Shane how big is 250 cubic kolometers
Yes there is evidence of climate change. The trends based on 50 years. There is no evidence that this is a normal cycle.
A peice of evidence that supports the chandzge in climate is, in 1850 there where 150 glacier at Glacier National Park now there is 26. Another piece of evidence is that the sea ice thickness decreased 43% from 1970 to 1990.
The global average sea level has risen 3.5 since 1993.
Fairbanks Alaska has gotten 2.5 degrees (farenheit) warmer.
Carbon Dioxide has increased by 2 billion tons per year.
Europe lost 50% of there Alpine glaciers.
Yes there is evidence of climate change. They based on the past 50 years. There is some evidence of normal cycles. Fire and Ice: Greenland lost up to 250 cubic kilometers (60 cubic miles) of ice annually between 2002 and 2006; Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005. Large wildfire activity increased dramatically in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons. The sea level has risen 3.5mm/a year since 1993. Fairbanks is 2.5 degrees Fahrenheit warmer. Carbon Dioxide is increasing by 2 billion tons each year.
The planet is not getting warmer it is getting colder. It is because of natural cycles.In 1850 there were 150 glaciers and there are 26. Sea ice thickness decreased 43% between the 1970's and 1990's.Global sea level rose up 6.7 inches in the last century.
There is a climate change. Glaciers are falling apart, wildfires, and lots of floods. i don't think this is a normal cycle except for all the wildfires there are in Texas. That might be normal. and plus its near the equator so its always hot in Texas. And the glaciers thats not normal. I hear that this might be global warming. And i have never seen so much rain in my life before.This is NOT a normal cycle to be happening like this. But wait till July we might not get any rain. Just a few drops and thats it.
The global average sea has risen about 17cm(6.7 in.) since 1993.
It is 2.5 degrees warmer in Fairbanks Alaska than 100 years ago.
Carbon dioxide has increased 2 billion tons per year.
The percentage of glaciers lost in Europe is 50%.
My thought are i think this is crazy. Is this a sign that this is the end of the world. This may be that global warming is taking its affect on Earth. And it is winning.
@ Tommy Cecil
It is Fairbanks tempurature not Minnesota.
@ Anthony,
Thats very fascinating about the volume of the glaciers in Switzerland being decreased.
Kelly Rogers- This might be the end of the Earth. is this a sign like I said in my blog. This can't be happening!!! I think that we might this world is going to be covered with rain/water.
1) Is there evidence supporting climate change?
Yes there is evidence of Global Warming
2) How long are the trends based? Is there evidence that this is a normal cycle?
The trends are about 50 years or so. There is no evidence that is a normal cycle.
3) Give me two pieces of evidence from the Fire and Ice Section that supports climate change
In 1850, Glacier National Park had 150 glaciers. Today there are 26.
Sea ice thickness decreased 43% between the 1970s and the 1990s.
4) How much has the global average sea level risen since 1993
Global sea level rose about 17 centimeters (6.7 inches) in the last century, but the rate in just the last decade is nearly double that of the last century.
5) How much warmer is Fairbanks Alaska than 100 years ago?
Fairbanks, Alaska is 2.5 degrees Fahrenheit warmer 100 years ago.
6) How much has carbon dioxide increased per year?
The carbon dioxide content of the Earth’s oceans is currently increasing about 2 billion tons per year.
7) What percent of Alpine glaciers has Europe lost?
Europe has lost 50% of its alpine glacier ice in the last century.
To Tony. I think that is weird that the alpines have lost 50% of their glacier.
There is evidence of climate change. The trends are based on the last 50 years. There is not evidence that this is a normal cycle. Glaciers National Park has gone from 150 glaciers to just 25 over 161 years. Sea ice thickness has decreased 43% between the 1970's and 1990's. 17cm. 2.5 degrees warmer. 2 billion tons per year. 50% of the alpine glaciers. I am confused on what to think about climate change.
Some evadeince I found was that...
1.In 1850, Glacier National Park had 150 glaciers. Today there are 26.
2.In 2008 the North Pole became an island for the first time in human history.
The two excamples are out of hundreds that show how much are climats changing.
there is some evidence of climate change.trends are based on on the recent times.yes there is some evidence of that there is part of a normal cycly.the sea ice decreced by 42%between the 1970s and the 1990s.but overall the glaicers in switzerland have decreced by two-thirds
@Jordan, I like the information you have
There is evidence supporting climate change. The trends are based on 50 years but there is no evidence that it is a normal cycle. Sea ice thickness decreased 43% between the 1970s and the 1990s.Large wildfire activity increased dramatically in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons.The global average sea level has risen 17 centimeters. It is 2.5 degrees hottter. 2 million tons more. Lost 50%
Kaleigh McCarthy
Yes, there is evidence of climate change. These trends are based on the past 50 years. Now Glacier Park only has 25 glaciers. Fairbanks Alaska is 11 percent drier and 2.5 degrees warmer than it was 100 years ago.
i agree with anthony its normal
yes theres evidence supporting climate change.theres no evidence its a normal cycle. sea thikness has went down by 43%it has 50%of glaciers.in 2008 the north pole became an island.
nathan stenger
this is to batmanstake there id evidence supporting climate change.
I agree with tony the climate is changing and it's changing fast. That's because for as long as humans existed we didn't care how much plants there are on the planet they were just there, but now the trees are getting cut down and there's not as much as there used to be. That's why we need to do something and soon.
Yes there is evidence of climate change.Thesetrends are based upon 50 years, but there is not evidence that this is a natural cycle, since the climate has changed this year and there is no evidence that relates in the past.
Fire and Ice- The volume of Switerland glaciers have decreased by 2/3. Also in 2008 the N. Pole became an island for the first time.
Since 1993 the global sea level has risen 3.5 mm/annually per year.
Fairbanks Alaska is 2.5 degrees fehreinheit warmer than 100 years ago.
Carbon dioxide increaased 2 billion tons per year.
Europe has lost 50% of the Alpine Glaciers.
jordan harbour
yes, there's plenty of evidence supporting climate change. one example would be,Sea ice thickness decreased 43% between the 1970s and the 1990s. the trends usually last about 50 years. there is evidence that this a normal cylce. aqn example is, Global sea level rose about 17 centimeters (6.7 inches) in the last century, but the rate in just the last decade is nearly double that of the last century. one example from fire and ice is meltwater, depending on its speed, sorts and rounds materials into layers of boulders, cobbles, pebbles, gravel, sand, silt or clay, in descending order of speed. This "outwash" forms below the terminal end of an alpine glacier. another one is Alpine glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas -- like downhill conveyer belts.Fairbanks Alaska is 2.5 degrees fehreinheit warmer than 100 years ago.Carbon dioxide increaased 2 billion tons per year.Europe has lost 50% of the Alpine Glaciers.
i was wondering the same thing about global warming! i really dont get it franklly because it just has been very cold over the past couple of years, and not very warm. the last time we had super hot weather, or at least what i remember, was 3 years ago when we had to be dismissed from school early because of the temperature, and drout. do you remember that? we were in the 4th grade. but yeah, there may be evidence supporting it but i just dont buy it! you're right it is probably just a normal cycle with a minor change and then after awhile, things go back to the way they're supposed to be. yeah sure the polar bears have a few less glaciers to lay around but that doesn't concern me even if i do like polar bears. (i do:D) On the other hand, like you said, the way everything has been changing things probably will not go back to normal.
Is there evidence supporting climate change?Deffinitely How long are the trends based?About 50 years Is there evidence that this is a normal cycle?Yes Give me two pieces of evidence from the Fire and Ice Section that supports climate change.Fires Increased because of hotter tempetures and Glaciers have melt. How much has the global average sea level risen since 1993.17 Cm How much warmer is Fairbanks Alaska than 100 years ago?2.5 degrees warmer How much has carbon dioxide increased per year?200 billion tons What percent of Alpine glaciers has Europe lost?43%
