A few of the main points of the third assessment report issued in 2001 include: An increasing body of observations gives a collective picture of a warming world and other changes in the climate system; emissions of greenhouse gases and aerosols due to human activities continue to alter the atmosphere in ways that are expected to affect the climate; confidence in the ability of models to project future climate has increased; and there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.
Contemporary global mean sea level rise will continue over many centuries as a consequence of anthropogenic climate warming, with the detailed pace and final amount of rise depending substantially on future greenhouse gas emissions.
This is because over the past three years, hundreds of new scientific field accounts of global warming's impacts, as well as improved peer - reviewed analyses of global warming itself in both the deep past and the very near future, have depicted earth's atmosphere as far more «sensitive» to the invisible CO2, methane and other human - sourced greenhouse gases than had been hoped.
First, the computer climate models on which predictions of rapid warming from enhanced atmospheric greenhouse gas concentration are based «run hot,» simulating two to three times the warming actually observed over relevant periods — during which non-anthropogenic causes probably accounted for some and could have accounted for all the observed warming — and therefore provide no rational basis for predicting future GAT.
Contemporary global mean sea level rise will continue over many centuries as a consequence of anthropogenic climate warming, with the detailed pace and final amount of rise depending substantially on future greenhouse gas emissions.
According to the Cato Institute's book summary, «Acknowledging that industrial emissions of greenhouse gasses have warmed the planet and will continue to do so over the next several decades, Michaels and Balling argue that future warming will be moderate, not catastrophic, and will have benign economic and ecological effects.»
It remains true that Earth has warmed more than 1 degree farenheit degrees over last century largely due to the buildup of human - made greenhouse gases... it remains the case that the projections of future climate change are every bit of discouraging as they were before the recent flap began.»
If we do nothing to reduce our emissions of greenhouse gases, future warming will likely be at least two degrees Celsius over the next century.
«With a high scenario for future greenhouse gas emissions, the largest warming occurs over the high latitudes of the Northern Hemisphere, but all land areas warm dramatically,» remarked Field
