CLIMATE SCIENCE

The Kyoto Protocol

Elites around the world tend to believe that rising levels of CO2 in our atmosphere will cause catastrophic climate changes. Collectively they wield enough power to shape energy policies in many nations according to commitments laid down in the “Kyoto Protocol” and subsequent accords. It is interesting to compare the fate of the Kyoto Protocol based on the work of “Climate Scientists” such as Michael Mann with that of the Montreal Protocol based on the work of people like McElroy.

The Montreal Protocol essentially banned the production of Freon and similar compounds based on the prediction that this would reduce the size of the polar “Ozone Holes”. After the ban went into effect the size of the ozone holes diminished. This may mean that the science presented by McElroy and his cohorts was “Robust” or it may…

Politicians from around the globe gather annually in the UNFCCC meetings so they can propose and fail to come to worthwhile agreements on how to limit global warming and its impacts.  Year in, year out, same thing.  For the results of the most recent failed gathering, see the WattsUpWithThat post GWPF Welcomes Non-Binding And Toothless UN Climate Deal.  One of the primary factors that drive the politicians is an attempt to limit global warming to 2-deg C above preindustrial values, where preindustrial is considered the mid-to-late 1800s.

But where did that 2 deg C limit come from?
