...looking at a wide range of observations from all over the world, the Met Office study concludes that the fingerprint of human influence on climate is stronger than ever. "We can say with a very high significance level that the effects we see in the climate cannot be attributed to any other forcings [factors that push the climate in one direction or another]," says study co-author Gabriele Hegerl of the University of Edinburgh...
There's plenty more evidence in the Met Office report to support global warming. But the question from critics remains: how can we be sure this isn't just a natural phenomenon? Scientists haven't done a good enough job of communicating how they distinguish human versus natural influences, says Hegerl. The answer lies in climate models - massive computer simulations that allow the scientists to project climate effects in various scenarios, including those in which humans do not emit any greenhouses at all. "We go out of our way to check out other explanations - by assuming it's all explained...
...more than 99% of the scientific details in the 2007 report have already withstood the most intense scrutiny. The fact that climate change evidence that was "very likely" a few years ago has now been declared likelier still by the comprehensive Met Office report suggests that the evidence for human-caused climate change is getting better all the time...
...course, clean coal technology does not diminish the environmental costs of extraction - to flora and fauna, and also to human well-being - say critics. Mountaintop mining destroys the natural habitats of many local species, whether endangered ones such as flying squirrels or flourishing ones like salamanders. Further, mountaintop debris that is dug up or displaced by explosions is dumped in the valleys below, burying headwater streams, killing the aquatic species that live in the waters and impacting downstream water supplies. About 1,200 miles of streams have been buried in this manner in central Appalachia, according to a 2003 federal...
What can be measured are chemicals like arsenic, lead, mercury, magnesium and selenium that leach into water sources from mining waste. Toxins have been found in high concentrations downstream of mountaintop mining sites, killing fish and threatening human health, according to biologist Dennis Lemly of Wake Forest University. Some residents of the Lindytown area rely only on bottled spring water for drinking. "No, ma'am, we do not dare drink the tap water here," Bonds says adamantly...
