How much has carbon levels risen within the last 100 years? How about temperature, within the last 100 years?

Question

Please include references.

I know the sea level will rise 40 ft within the next 500 years... soo, yeah. (Saw it in a TV program)

A chart would be helpful.

Thanks.

PS: NOT HOMEWORK!

Answer 1

Average global temperature has risen .7 degrees Celsius in the past 100 years (estimate taken from http://en.wikipedia.org/wiki/Image:Instrumental_Temperature_Record.png )

Average carbon levels risen from estimated 295 to 360 parts per million (1895-1995, from http://clinton4.nara.gov/Initiatives/Climate/greenhouse.html )

Hope this helps

In response to a later remark about the CO2 graph in Wikipedia, that graph is scaled to thousands of years, so 100 years cannot be estimated well. The graph in the link above is more accurate at the smaller scale.

Answer 2

I'm not going to worry about 500 years from now,because I won't live that long.
There is a lot of debate going on about global warming and greenhouse gasses,the problem is that both sides of the issue are not being presented in the news media and not all the so called earth friendly activities are friendly to the environment.
Take recycling newspapers for example: Gardeners use old newspapers in the garden for planting,mulch and to cover plants when a light frost is expected. The paper breaks down and becomes part of the soil. To recycle newspapers into new paper,the newspaper has to have the ink bleached out and chemically treated,this creates another toxic waste to be disposed of.
Some cities require the residents to separate their trash before setting it out for collection. It costs the cities more because they have to hire people to sift through the trash to make sure it is separated. If done right the first time,a landfill can be recycled over and over,without expanding the amount of land needed.
Recycling aluminum is OK,recycling glass takes more energy and the colored glass has to be separated according to color (adding to the cost)

Answer 3

I don't know the specific place to get a chart, but you could try renting the ex-vice presidents movie on global warming. As for your question there are different types of carbon levels. For instance chlorofluorocarbons destroy o3 molecules(ozone). The problem is they take many years (CFC) to reach the ozone. So the information you ask for can be interrupted in different ways. Basically the ozone we see today is because of what we did about 20 years ago.

Answer 4

Nature Nate was Sooooo close. He got the temperature graph from the wikipedia global warming article but missed the CO2 graph from the same article. The first source is the graph and the second is the wikipedia article it came from.

Chicken Little thought the sky was falling, is your name chicken little? I dont believe that crap none of it. There are many nuts out there with so many ideas. Hang around you will see more.
