in the last ten years what has been the global temperature rise?

Answer 1

0.230°C / 0.414°F

When specifying global temperature changes it's necessary to work with averages in order to iron out anomolies caused by above or below average conditions in a given year.

In the 10 years leading up to 1996 the average global temperature was 14.329°C, in the 10 years up to 2006 it was 14.559°C, a rise of 0.230°C.

The natural rate at which the world warms up is 0.0005°C per year (9°C in 18,000 years) so of the 0.230°C rise in the last 10 years we would expect 0.005°C to be natural and the remaining 0.225°C to be anthropogenic.

10 years is a short time span in terms of climate, more reliable data could be obtained by looking at how temperatures have changed over a longer period, say 50 or 100 years.

To Gina: NASA publishes up to date info and this page http://data.giss.nasa.gov/gistemp/tabledata/GLB.Ts.txt has monthly temperature data right up to last month, it's not in the most user friendly format and you'll have to play about with the numbers a bit. There's other records available from this page... http://data.giss.nasa.gov/gistemp/

To Bats Fanfilm: Please check your facts. The story of global warming on Mars is an erroneous one. In the absence of evidence to disprove global warming certain quarters resort to inventing evidence, it's wise to make a habit of checking where the information comes from. In this instance it stems from a NASA report entitled 'Mars Is Melting' which points out that each spring the south polar ice cap melts and the north polar ice cap freezes, the opposite happens in fall. It's a seasonal variation - nothing more, nothing less.

Answer 2

About .2 degrees from 1990 to 2000, and about .2 for the ten years before that. There is a nifty graph on the link below, and a lot of other information about climate change on the site. I can't seem to find more recent data for average global annual temps, perhaps they are not all done pondering them yet.

Answer 3

Some 'net sites give global temperature, in the last 10 years, up: ~ 2 to ~3 Celsius degrees.

Answer 4

Yes, it has been steadily rising, and for a long time it seemed that it was the emissions of gas-powered cars that were going to be the harbingers of our doom.

Until it was discovered that the polar icecaps of Mars are melting too. It seems that the ENTIRE Solar System is heating up. If we're on our last legs, if may very well be because our dear star Sol is burning out.

Answer 5

around 0.25 degrees.

Answer 6

0.2 degrees above Al Gore's I.Q.. In other words, 0.2.

Answer 7

zero
