Hansen et al. 1981
Hansen, J., D. Johnson, A. Lacis, S. Lebedeff, P. Lee, D. Rind, and G. Russell, 1981: Climate impact of increasing atmospheric carbon dioxide. Science, 213, 957-966, doi:10.1126/science.213.4511.957.
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.
Yes, the effects of CO2 increase the intensity of droughts in drought prone areas. Simply witness what is going on in California and the rest of the West at present. The fires in Oregon and Washington, about 1000 square miles burned at present, and the fires are still growing. California is still in drought, hopefully the El Nino will bring some moisture.
Yep -- the WitchDoc of Climate Weirdness. About the same time as that paper, ole Doc James went in front of Congress and told them that "that we see the effects of Climate Change TODAY".. Would be about 20 years before he actually authored a paper ATTEMPTING to back up that claim. And he told Congress to expect 8degs additional heating by 2100.. . Very few others (maybe 10 or 12) who have stuck out their necks that far to give cover to politicians. Same James Hansen dramatically told about the inevitable effects of "boiling the oceans" which the mental midgets in the press have had a field day with ever since.. The same dude who used to equate the 0.5deg rise in his lifetime to the release of 40,000 Hiroshima bombs. A trick so fantastic that SkepShitScience has a real-time atom bomb counter on most every page of their juvenile website..
This is the same guy who was head of NASA agency that is STILL (almost monthly) changing temperatures back to the 1920s in order to claim new "unprecedented records" for the GW propaganda press releases.. Chicken Little in charge of the kitchen..
GoldiRocks recently admitted that there is Virtue in being an "activist" climate scientist.. That's why Doc Hansen is his superhero...
