Global warming. is there good graphs that explain it?

Question

i need graphs to help me do my report about Global Warming.
i need good website not like wikipedia.org
i need one that is 100% true
so plz can anyone help me

Answer 1

i hope you understand that when dealing with a scientific phenomena as complex as global warming, everything is estimates, nothing is 100% true.

Temperature increase plotted next to solar activity and CO2 concentration in the atmosphere:

estimated contribution of components using a computer model- plotted next to the observed temperature:

Two places have a lot:

Some of my favorites are:

http://www.globalwarmingart.com/wiki/Image:1000_Year_Temperature_Comparison_png

http://www.globalwarmingart.com/wiki/Image:Climate_Change_Attribution_png

All have references to the peer reviewed scientific literature. 100% true.

jim z's graph isn't bad, but his interpretation is wrong.

Note that the graph goes backwards, right to left. The top three graphs are the three pieces of the Milankovic cycle. Note that two out of three are headed down. The 4th is the total, the combination of the first three. It is total solar radiation. Note that it too is headed down.

Solar radiation is decreasing now. But we're warming, because of CO2. Details:

Answer 3

If you really want to understand it, look at the attached graph on the bottom. It shows temperature and time over the last 1,000,000 years. Note that to the left is now and a million years ago to the far right. It shows that we have gone through several episodes of glaciation and subsequent warming. As can be clearly seen on the graph we have been on a warming trend for the last several thousand years. Because the graph is nearly vertical in the last 10,000 years, that indicates it has been warming rapidly. Those that pretend that evidence proves the latest bit of warming is caused man are ignorant of the facts in my opinion and are generally engaged in pushing a political agenda that has more to do with socialism than science IMO. http://en.wikipedia.org/wiki/Milankovitch_cycles

Answer 4

This is a horrible topic for the fact that all agencies that are involved have graphs that are different from everyone else. I'm not sure of the website exactly, but do a search for the International Panel on Climate Change (IPCC)

Answer 5

That first post (patrick) gives good data and plots

What you want to show is that until like 1900-1950
everything is pretty much flat, or oscillations cancel out, but around 1950 levels suddenly change and rise, then
it is most likely due to human devt rather than nature.
