The science, we were told some years ago is settled. But now, it appears, we are not so sure anymore.
In 2007, the Intergovernmental Panel on Climate Change (IPCC) warned the world that a climate catastrophe was just around the corner, if we didn’t curtail carbon dioxide (CO2) emissions. The IPCC was awarded a Nobel peace prize for that work. Co-Nobel-laureate Al Gore has made millions from his book and (so-called) documentary film An Inconvenient Truth, prognosticating doom and gloom.
