The Honest Broker (8/15/25) Substack: "In 2024, Nature published 'The Economic Commitment of Climate Change,' by Kotz et al. (KLW24). A press release accompanying the paper’s publication announced that it projected enormous future GDP losses due to climate change, much more than almost all other studies:
Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study published in 'Nature' finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees.
The paper’s extreme results got a lot of attention — According to CarbonBrief, in all of 2024, KLW24 was the second most mentioned climate paper in the media... Much more important than the media frenzy, KLW24 quickly found its way into important policy settings, including the U.S. Congressional Budget Office, the OECD, the World Bank, and the UK Office for Budget Responsibility. Most importantly, the Network for Greening the Financial System (NGFS), a consortium of more than 100 central banks from around the world, adopted the study’s results into a new official NGFS 'damage function' to project the future costs of climate change, and thus shape how governments and businesses think about and respond to climate change... Given its wide reach and impact, it seems obvious that the methodologies used by the NGFS should be accurate and unbiased. We now know, however, that KLW24 and its application in policy by the NGFS and others are fatally flawed... In a response to KLW24 published last week in Nature, Bearpark et al. (BHH25) showed that correcting inaccurate data from Uzbekistan in KLW24 reduces their estimate of projected 2100 damages due to climate change by about two thirds."

"A new, reformed and pared-down Jones Act would boost manufacturing jobs in the US, lower prices for American consumers around the world, and boost US exports. Most importantly, it would make Americans safer by boosting naval capacity."
