A report by an international scientific panel says it's "extremely likely" that human activity is the dominant cause of global warming.
The Intergovernmental Panel on Climate Change previously assessed in 2007 it was "very likely" that global warming was man-made.
The IPCC now says evidence has grown thanks to more observations, a better understanding of the climate system and improved models to analyze the impact of rising temperatures.
The IPCC says a human footprint can be found in the warming of the atmosphere and oceans, in rising sea levels, melting snow and ice and in changes in some climate extremes.
Sen. Jim Inhofe, a senior member of the Senate Environment and Public Works Committee, made the following statement regarding the report:
“Today’s release of the IPCC’s Fifth Assessment Summary for Policymakers proves that the UN is more interested in advancing a political agenda than scientific integrity. The IPCC glossed over the ongoing fifteen-year pause in temperature increases and did nothing to suggest that their predictions might be wrong. With climate change regulations expecting to cost the U.S. economy millions of jobs and between $300 billion and $400 billion in lost GDP a year, we can’t afford to act on politically charged media alarmism. Let’s not forget the article published in the New York Times in 1975 that reported ‘a major cooling of the planet’ was ‘widely considered inevitable.’ To me, this all appears to be business as usual.”
On Thursday, Inhofe filed two climate change related amendments.
Amendment 1997 would prohibit the Environmental Protection Agency from regulating greenhouse gas emissions from power plants.
And amendment 1996 would prohibit the Administration from participating in international climate change negotiations unless the U.S. offers an addendum to the latest IPCC report stating that anthropogenic climate change is a scientifically unproven theory.
