800,000 years of Ice Core temperature data from Antarctica The data graphed here is from the NOAA web pages Note that there have been many periods of Ice Ages followed by warm periods. Many of the warm periods previously have been hotter than the present warm period. We are living in a cold inter-glacier time. It could be one to three degrees hotter on average than it has been for the last 10,000 years and still be normal. Also note that the periods between ice ages are SHORT. We are most likely about to enter into another ice age very soon. Very soon could be next year. Or perhaps a few hundred more years, but most likely within 1,000 years. |
The data files ends at 1950. But we have good data for 1950 to the present times and yes, there has been some increases in temperatures during that time, and some decreases now. It's the same as has happened several times during this recent break in the ice ages.
