No Consensus on Climate Change?

You are always hearing that there’s no consensus on climate change even among scientists. There have been two studies out recently that disproves that. Late last year James Lawrence Powell conducted a survey of scientific papers on climate change.  He found, “By my definition 24 of the 13,950 articles, 0.17% or 1 in 581, clearly reject human-caused global warming or endorse a cause other than CO2 emissions for observed warming. The articles have a total of 33,690 individual authors (rounded to 33,700 in the figure). The 24 rejecting papers have a total of 34 authors, about 1 in 1,000.”

Yes, that’s 33,690 individual authors with only 34 rejecting human-caused global warming. You can find the numbers here

More recently a similar study showed that there was a 97% “consensus among papers taking a position on the cause of global warming in the peer-reviewed literature that humans are responsible.” This study can be found here. In fact this study states that, “frankly, every scientist doing climate research knows humans are causing global warming. There’s no longer a need to state something so obvious. For example, would you expect every geological paper to note in its abstract that the Earth is a spherical body that orbits the sun?”


So where is the disagreement? It’s only in the minds of the media and conservative bloggers and politicians and the people that listens to them.
