In February 2007, the International Panel on Climate Change (IPCC) released the executive summary for an authoritative report evaluating the risk of anthropogenic climate change, based predominantly on peer-reviewed scientific literature. The panel, consisting of over more than 2500 scientific experts, 1300 lead and contributing authors, and represented by over 113 governments, is considered to be one of the most authoritative and, at times conservative, panels researching the causes and consequences of climate change. Among other findings, some of the many important conclusions by the group are:
“…[A] very high confidence that the globally averaged net effect of human activities since 1750 has been one of warming…”
“Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.”
“Continued greenhouse gas emissions at or above current rates would cause further warming and induce many changes in the global system during the 21st century.” (IPCC Report)
However, the IPCC is far from the only group defending the idea that global warming is anthropogenic. In fact, even a cursive glance at the scientific community’s attitude towards the issue of global warming shows that a plethora of isolated groups have come to the same conclusions.
