UN Report Downgrades Human Impact on Climate
GodInHell writes to mention an article in the Telegraph, stating that man's impact on the environment has been 'downgraded'. A UN report has found that our species has not had as large effect on climate change as was previously thought. The average temperature is still due to rise almost 5 degrees C in the next 100 years, bringing drastic changes in weather patterns. From the article: "The panel, however, has lowered predictions of how much sea levels will rise in comparison with its last report in 2001. Climate change skeptics are expected to seize on the revised figures as evidence that action to combat global warming is less urgent. Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming."
here are many, many other pollution problems--sulfur dioxide / acid rain being one of them. China for instance today has huge sulfur dioxide emissions, roughly comparable to the US 25 years ago before we got good about it.
Which is fortunate because sulfur dioxide combats global warming sort of the same way a nuclear winter combats global warming, but to a smaller scale. Many scientists are considering increasing sulfur dioxide emissions in certain locations if we can't do anything else to stop global warming.
