The reason they returned to the 1.5 to 4.5 range is because there was virtually no global warming since 2000 (the so called “hiatus”), which is embarrassingly inconsistent with a large climate sensitivity.What’s more embarrassing is that over almost 4 decades of research and billions of dollars (and pounds) invested in climate research we don’t know the answer to the most important question any better? The body of evidence however clearly shows that the climate sensitivity is on the low side, about 1 to 1.5 degree increase per CO2 doubling.
Over geological time scales, the lack of correlation between CO2 and temperature places a clear upper limit of a 1.5°C per CO2 doubling sensitivity.If all of humanity spits into the ocean, will sea level rise appreciably?In fact, there is no single piece of evidence that proves that a given amount of CO2 increase should cause a large increase in temperature.450 million years ago there was 10 times as much CO2 in the atmosphere but more extensive glaciations.When you throw away the chaff of all the fallacious arguments and try to distill the climate science advocated by the IPCC and alike, you find that there are actually two arguments which appear as legitimate scientific arguments, but unfortunately don’t hold water. The first is that the warming over the 20th century is unprecedented, and if so, it must be human.Having honest debates in Israeli academia or in the media is actually the norm.
Below you will find the summary I wrote myself before the debate.
Last week I participated in an interesting debate that was held at the Cambridge Union, the oldest debating club in the world (dating back to 1815.
The invite was to be on the side opposing the proposition “This house would rather cool the planet than warm the economy”.
Oddly enough, the range quoted by the IPCC, which is 1.5 to 4.5°C per CO2 doubling was set, are you ready for this, in a federal committee in 1979! All the IPCC scientific reports from 1990 to 2013 state that the range is the same.
The only exception is the penultimate report which stated it is 2 to 4.5.
Since it is rather concise I thought it would be a good idea to bring it here as well.
