Is there a scientific consensus on global warming?

There is a popular perception that climate scientists are in almost unanimous agreement that increasing CO2 concentrations are causing dangerous man-made global warming, and that we need to urgently reduce our “carbon footprint”.

However, while there are many prominent climate scientists who believe this, there is actually a wide range of opinions on man-made global warming amongst the scientific community. Some scientists believe there has been man-made global warming, but that the media descriptions are seriously exaggerated, and that it isn’t an urgent issue. Other scientists believe that global warming is probably due to natural climate variability.

In this essay, we give examples of some of the different views on man-made global warming of prominent climate researchers.

What does the IPCC say?

The reports of the U.N.’s Intergovernmental Panel on Climate Change (or IPCC, for short) are widely assumed to represent the scientific consensus of thousands of top climate scientists on man-made global warming. The reports claim that man-made global warming is real, serious and will become more serious during the 21st century if nothing is done to slow down CO2 emissions.

Therefore, it is assumed that these claims represent the views of all the top experts involved in the writing of the IPCC reports. However, in this essay, we find that most of the IPCC scientists are never asked for their views on those claims, and that several IPCC scientists openly disagree with them.
