255 members of the U.S. National Academy of Sciences, including 11 Nobel laureates, have penned a letter in Science slamming the disinformation campaign orchestrated by a small network of climate deniers that has confused the public about the real danger of climate disruption.

The scientists’ letter, published in the May 7th issue of the journal Science (subscription req’d), says:

“We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular.”

The scientists note that the fundamental science of climate change is sound, despite the extensive campaign by deniers and skeptics to confuse politicians and the general public:
 
“There is compelling, comprehensive, and consistent objective evidence that humans are changing the climate in ways that threaten our societies and the ecosystems on which we depend.”

A group of the nation’s leading environmental scientists is calling on the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to stop issuing new mountaintop mining permits, arguing that the ecological and human health costs of the controversial mining practice are “pervasive and irreversible.” 

The group of scientists published the first comprehensive assessment of the ecological and health impacts of mountaintop removal mining today in the journal Science, describing how the impacts of current and former mountaintop removal operations will be felt for centuries, with major implications for water quality, biodiversity, and human health.  Shockingly, there’s never been a comprehensive assessment of MTR impacts until now.

Published only a few days after the Obama EPA misguidedly approved the expansion of Hobet 45, part of the largest mountaintop removal coal mine in West Virginia, the paper concludes that mountaintop removal’s impacts are much too steep to justify.  The authors’ analysis of peer-reviewed research unequivocally confirms irreversible environmental impacts from mountaintop removal, a practice that also exposes local residents to a greater risk of serious health problems.
