Studies show Earth warming more slowly than predicted
by Craig Idso and James Taylor
Sound science dealt several devastating blows to global warming alarmism during the past few weeks, despite the best efforts of global-warming activists to sustain the drumbeat of climate fear.
Attempting to drum up fear about global warming in the San Antonio Express-News, Andrew Dressler and Gerald North wrote an Oct. 6 article titled, ?Climate change is real and denial is not about the science.? In their article, they
claimed political ideology rather than scientific evidence motivates skepticism toward their assertions of a global warming crisis. In reality, sound science continues to deliver blow after blow to claims of a global warming crisis.
On Sept. 17, the Nongovernmental International Panel on Climate Change released Climate Change Reconsidered II: Physical Science, or CCR-2, containing more than 1,000 pages of scientific research indicating global warming is not an impending crisis. Forty-seven scientists contributed to CCR-2, presenting nearly 5,000 citations of peer-reviewed studies exposing flaws in global warming alarmism.
The following week, the United Nations Intergovernmental Panel on Climate Change, or IPCC, released its Fifth Assessment Report, which backtracks on many prior IPCC predictions and contradicts many of the most frequent assertions made by global warming activists. The IPCC report contradicts claims that global warming is causing more extreme weather, acknowledges global warming is occurring more slowly than the IPCC previously predicted and predicts less future warming than previous IPCC reports.
Several peer-reviewed studies published during recent weeks reinforced the lack of a global warming crisis. For example, a study in the peer-reviewed Nature Climate Change reported global warming is occurring more slowly than what was predicted by 114 of 117 climate models relied on by the IPCC and other government agencies. Real-world warming is occurring at merely half the pace projected by most climate models, the study found. The peer-reviewed Geophysical Research Letters reported Earth is undergoing substantial greening as a result of higher carbon dioxide levels and more-favorable weather conditions.
Global hurricane frequency is undergoing a long-term decline, with global hurricane and tropical storm activity at record lows during the past several years. The United States is benefiting from the longest period in recorded history without a major hurricane strike. Tornado activity is in long-term decline, with major tornado strikes (F3 or higher) showing a remarkable decline in recent decades.
Sound science ? supported by objective, real-world data ? indicates humans are not creating a global warming crisis.
