Hansen, J., D. Johnson, A. Lacis, S. Lebedeff, P. Lee, D. Rind, and G. Russell, 1981: Climate impact of increasing atmospheric carbon dioxide. Science,

The global temperature rose 0.2°C between the middle 1960s and 1980, yielding a warming of 0.4°C in the past century. This temperature increase is consistent with the calculated effect due to measured increases of atmospheric carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean trend of increasing temperature. It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980s.
Potential effects on climate in the 21st century include the creation of drought-prone regions in North America and central Asia as part of a shifting of climatic zones, erosion of the West Antarctic ice sheet with a consequent worldwide rise in sea level, and opening of the fabled Northwest Passage.

(ISNS) -- The drought that devastated Mongolia in the early part of the last decade killed tens of millions of livestock, forcing hundreds of thousands of people to flee the countryside and seek new lives in the capital city of Ulaanbaatar — a shift that has been transforming the country ever since.
Researchers now know that the drought was the hottest of the last 1,000 years and was likely exacerbated by global warming.
As global temperatures continue to rise this type of severe drought could become more frequent, with potentially drastic consequences to central Asia, according to researchers.
