A paper published in the journal Science in August 1981 made several projections regarding future climate change and anthropogenic global warming based on manmade CO2 emissions.
The paper, written by a team of atmospheric physicists led by the now controversial James Hansen at NASA Institute for Space Studies at Goddard Space Flight Center, buy canada goose jacket was recently rediscovered by researchersGeert Jan van Oldenborgh and Rein Haarsma from canada goose coats on sale the Royal Netherlands Meteorological Institute (KNMI). Taking a break Canada Goose online from research due to illness, the scientists got a chance to look back goose outlet canada through some older, overlooked publications.
Even though the cheap canada goose paper was given 10 pages in Science, it covers a lot of advanced topics related to climate indicating the level of knowledge known about climate canada goose clearance sale science even at that time.
concepts and conclusions have not changed all that much, van canada goose outlet nyc Oldenborgh and Haarsma note. et al clearly indicate what was well known (all of which still stands today) and what was uncertain. the paper, several graphs note the growth of atmospheric carbon dioxide, both naturally occurring and manmade, and projected a canada goose outlet uk future rise based on the continued use of fossil fuels by humans. Van Oldenborgh and Haarsma overlaid canada goose outlet parka data gathered by canada goose jacket outlet NASA and KNMI in recent years and found that the projections made by Hansen et al. This temperature increase is consistent with the calculated greenhouse effect due to canada goose outlet measured increases of atmospheric buy canada goose jacket cheap carbon dioxide. Variations of volcanic aerosols and possibly solar luminosity appear to be primary causes of observed fluctuations about the mean rend of increasing temperature. It is canada goose coats 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 1980 Potential effects on climate in the 21st century include the creation of drought prone regions in North America and central Asia as official canada goose canada goose uk black friday outlet part of a shifting of climate zones, erosion of the West Antarctic ice sheet uk canada goose with a consequent worldwide rise in sea level, and opening of canada goose outlet canada the fabled Northwest Passage. here we are in 2012, looking down the barrel of the global canada goose outlet shop https://www.rkliedtke.de warming gun Hansen and team had reported was there 31 years earlier. In fact, we already seen most of the predicted effects take place.
regions are receiving less rainfall, the Antarctic ice has begun to crack and crumble and bowhead whales are using the Northwest Passage as a polar short cut.

And that not the only prediction that seems to have canada goose outlet online uncannily come true.
light of historical evidence that it takes several decades to complete a major change in fuel use, this makes large climate change almost inevitable, Hansen et al wrote in anticipation of the difficulties of a global shift away from dependence on carbon dioxide emitting fossil fuels.
effects on climate canada goose outlet in usa may make full exploitation of coal resources undesirable, the paper canada goose outlet jackets concludes. appropriate strategy may be to encourage energy conservation and develop alternative energy sources, while using fossil fuels as necessary during the next few decades. True advancement will rely on our acceptance that a change is in fact necessary a hurdle that is proving to be the most difficult one to clear.
