Declaring that “human influence on the climate system is clear,” a U.N.-assembled panel of scientists “it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.”

The Intergovernmental Panel on Climate Change, which brings together hundreds of researchers from around the world, adds that “warming in the climate system is unequivocal and since 1950 many changes have been observed throughout the climate system that are unprecedented over decades to millennia.”

Looking ahead, panel co-chair Thomas Stocker warns that “continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. … Heat waves are very likely to occur more frequently and last longer. As the Earth warms, we expect to see currently wet regions receiving more rainfall, and dry regions receiving less, although there will be exceptions.” Continue reading “It’s Clear Humans Are Changing World’s Climate, Panel Says”

UN report: Humans are ‘dominant’ cause of global warming

By Ben Geman – 09/27/13 05:16 AM ET

A United Nations climate science panel has concluded global warming is “unequivocal” and there’s at least a 95 percent chance human activities are the main driver of temperature increases over the last six decades.

“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia,” states Friday’s report from the UN’s Intergovernmental Panel on Climate Change (IPCC).

“Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes,” the report finds. “It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.” Continue reading “UN report: Humans are ‘dominant’ cause of global warming”

WASHINGTON (September 9, 2013) – The federal government has fast-tracked approval of thousands of dangerous pesticides and potentially put public health at needless risk, the Government Accountability Office reported today.

The report by the investigative arm of Congress confirms earlier findings by the Natural Resources Defense Council that the Environmental Protection Agency is doing too little to protect the public from harmful pesticides.

EPA Scientists Deem Benzo(a)pyrene a Cancer-causing Chemical

On Aug. 21, the U.S. Environmental Protection Agency (EPA) published a draft revised health assessment of the toxic chemical benzo(a)pyrene (BaP). This chemical is widely found in the environment and in a number of workplaces, and in its assessment, EPA declared that BaP causes cancer.
