Before the jump, here is an excerpt from my New York Post op-ed from earlier this week, which built upon the first installment of a new series from THB, on insurance and climate: The headlines are relentless, loudly proclaiming that climate-fueled extreme weather has caused an insurance…

How the Financial System Invented “Climate Risk” Untethered from Climate Science
Part 1 of the THB series on climate change and insurance focused on the recent financial performance of the insurance industry in the context of fevered claims of its looming collapse due to climate-fueled extreme events.

A Huge Retraction, the Usual Playbook, and Reason for Optimism
Some huge news dropped today that will reverberate through climate science and policy. Nature has finally retracted “The Economic Commitment of Climate Change,” by Kotz et al.

It is not just the retraction…

The Battle for Climate Science and Policy Past—And Why It Matters
Last week in Belém, Brazil the 30th Conference of Parties to the U.N Framework Convention on Climate Change (UNFCCC) concluded with little accomplished, according to most observers. Perhaps the most significant accomplishment was formalizing a fully Orwellian characterization of the recent history of climate policy — See my post last week for why the UNFCCC characterization of moderating…

In 2015 in Paris, countries from around the world agreed to accelerate the decarbonization of their economies in response to climate change.

The Last Gasp of the Climate Thought Police
Following my lecture last week at Cornell, one Cornell professor, a well-known climate activist, called for the firing of the director of the Cornell Atkinson Institute for Sustainability — an accomplished scientist himself — simply for hosting my visit.

I was warmly welcomed and had a chance to discuss, debate, listen, learn, agree, disagree, and break bread with many colleagues. In short, my visit revealed…
