The latest United Nations Intergovernmental Panel on Climate Change (IPCC) report shows that human activity has caused at least half of climate change in the last half-century. U.N. said they are 95% certain of this. This is a large spike in confidence, in 2007 scientist were 90% certain and in 2001 it was 66%.
“It should serve as yet another wake-up call that our activities today will have a profound impact on society not only for us but for many generations to come,” Michel Jarraud, Secretary General of the World Meteorological Organization, which co-sponsored the IPCC.
Even with this increase in certainty of man-made climate change, some still deny it. Sen. James Inhofe issued this statement following the release of the IPCC 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.”
U.S. Secretary of State John Kerry had some strong words for climate change deniers in a statement released about the report.
“This is yet another wakeup call: Those who deny the science or choose excuses over action are playing with fire.
Once again, the science grows clearer, the case grows more compelling, and the costs of inaction grow beyond anything that anyone with conscience or common sense should be willing to even contemplate.
Boil down the IPCC report and here’s what you find: Climate change is real, it’s happening now, human beings are the cause of this transformation, and only action by human beings can save the world from its worst impacts.”
One of the most concerning finds in the report is that it could be too late to make any real difference anytime soon.
“Many aspects of climate change will persist for centuries even if concentrations of greenhouse gases are stabilized. This represents a multicentury commitment created by human activities today.”
Oklahoma has had many extreme weather events since the 1950’s that climate change likely played a role in. We have seen a dramatic increase in extreme weather, especially record heat and heavier precipitation events, all over the world. While it’s difficult to know the exact role of climate change in individual weather events, like the Moore EF-5 tornado in May or the current drought, patterns do show that climate change does play a role in extreme weather.
