Extreme weather & Climate Change: Media Hype OR Reality?

By Madhav Khandekar* Toronto, Canada The recent extreme heat episode (June 29- July 5, 2021) over the NW region of Canada-USA led to highest recorded temperature of 49.7C in Lytton (British Columbia) in Canada. This unusual weather event was caused by a development of a ‘heat dome’ resulting from a persistent high-pressure [...]

Can we predict long-term solar variability?

By Andy May This post is a result of an online conversation with Dr. Leif Svalgaard, a research physicist at Stanford University. Leif knows a great deal about the Sun and solar variability and can explain it clearly. Our disagreement is over whether long-term solar variations could be large enough to affect Earth’s climate [...]

Climate Sensitivity to CO2, what do we know? Part 2.

In Part 1, we introduced the concepts of climate sensitivity to CO2, often called ECS or TCR. The IPCC prefers a TCR of about 1.8°C/2xCO2 (IPCC, 2013, p. 818). TCR is the short-term, century scale, response of surface temperature to a doubling of CO2, we abbreviate the units as “°C/2xCO2.” In these posts we review lower [...]

Climate Sensitivity to CO2, what do we know? Part 1.

The IPCC claims, in their AR5 report, that ECS, the long-term temperature change due to doubling the atmospheric CO2 concentration or the “Equilibrium Climate Sensitivity,” likely lies between 1.5° and 4.5°C, and they provide no best estimate (IPCC, 2013, p. 85). But their average model computed ECS is 3.2°C/2xCO2. Here, “°C/2xCO2” is the temperature change [...]

Unsettled: “most important book on climate science in decades”

Reviewed by Rupert Darwall May 20, 2021 On January 8, 2014, at New York University in Brooklyn, there occurred a unique event in the annals of global warming: nearly eight hours of structured debate between three climate scientists supporting the consensus on manmade global warming and three climate scientists who dispute it, moderated by [...]
