So you are suggesting that temperatures have been rising the last 10 years?
Yes, the underlying trend line has over the years from 1998 to to 2008 gone up by 0.08 degrees . 1998 was a spectacularly hot year, and so is selected to minimse the rise of temperature. If you remove the 1998 value and go from 1999 to 2008 then it increases to .24 degrees
Ten years sounds good, but if you go back five years, skeptics were selecting the figures as going back 5 years, because that was the ammount that made it seem as if global warming was not happening. (The fact that the data existed over much longer timescales and makes the denialist argument look rather silly was always avoided)

Oh and looking at this years figures, (If you go 1999 to 2009) it comes to 0.4 degrees.

That's a lot of degrees.

Haha yeah.
The earth isn't warming!
Even if it is it's not much! What can .4 of a degree possibly add up to over time?
You useless tosser

HEY DONT WE ALL LIKE WARM WEATHER ANYWAYS

Not those of us who enjoy winter sports.
Also, whatever happened to global cooling? As recently as last year I heard a little bit of buzz on NPR, with some scientist talking about how it was still a possibility.

Global cooling isn't happening now.
But that is not to say it won't.
We are in new territory here and no one knows how it will pan out.
Are the fixed ocean currents around the world changing?
They are a major components in driving our weather system and it seems as if increased melt water at both poles is having an affect.
It's possible that we are entering another glacial period and our actions are hurrying it along.
Or that we are entering a glacial period and our actions are delaying it.
Or we are not due to enter a glacial period for another 15,000 years.
It isn't known
But what is known is that we are dependent on an increasingly scarce fuel source.
And by happy coincidence if we move to different methods of producing energy, we can reduce some of the factors said to be causing climate change.

Global cooling was a theory from the late 1970's when Glaciation and soot particles in the air were being studied. One scientist wrote a book called the Cooling, which was picked up by a number of newspapers and Newsweek magazine. (The book was called the coolng by the way) It was one theory amongst many, blown out of all proportion by a publishing companies PR machine. The actual book isnt bad, and has a fair discussionof the science. It says, if things carry on as they are were heading for climate disaster, and from the evidence I see the most likely factors in the end are particulate cooling to cause massive cooldown. but more research needs doing.
Well the more research got done, and it turns out that particulate cooling is a very minor effect, thousands of studies showed that it is completely overshadowed by greenhouse gas effects. And these effects are shown by multiple experiments, going back through thousands of years of data

Plus you've got the whole "excess CO2 in the atmosphere traps heat causing temperature rise, but STUPID excess CO2 in the atmosphere stops heat even getting in in the first place, causing ice age".
So first one, then t'other.
