Global Warming Science Update: Natural Forces Slow Warming
Nicolas Loris /
University of Wisconsin-Milwaukee mathematicians Kyle L. Swanson and Anastasios Tsonis are predicting that global temperatures will change very little or even drop over the next decade – and possibly longer:
Tsonis and Swanson used mathematical analysis to look at the role of the Earth’s natural climate cycles and the long-term weather patterns that drive them. The Earth’s global mean temperature swings up and down over time. It fell before World War I, increased during the 1920s and 1930s, fell again during the 1940s until about 1976. Then, global temperatures rose from 1976 to 2001. But the trend in mean temperatures since 2001 has been flat, said Tsonis, and is beginning to fall.
