I have no complaints. I’m embarrassed I didn’t explicitly say you richly deserve the credit for your contributions to climate change scholarship. But I assumed you knew I thought that. .. Hard to imagine you with flaming auburn hair.

You are too kind Richard — and it is a bizarre ranking. Reuters put Keywan Riahi first. There are many other highly productive researchers missing.

Fix peer review! I receive up to 15 invitations weekly to review manuscripts. I will not spend my time in 2026 registering for your journal just to decline an invitation. I will not review low quality manuscripts, manuscripts not relevant to my research, and will not review in 5-10 days.

True. But CO2 also reduces the nutrient density of wheat, rice, barley, grasses, trees, … all C3 plants; thereby reducing concentrations of protein and B vitamins. CO2 also reduces micronutrients, potentially affecting the health of hundreds of millions of people.

Thank you Sadie for thanking @wellcometrust.bsky.social and @thelancetplanet.bsky.social. I should have done so. Wellcome’s technical and financial support were instrumental. And Lancet Planetary Health published when Environmental Health Perspectives could not. The author team is amazing.

Stoked to be part of this awesome group and study "Priority climate and health modelling needs" just out in @thelancetplanet.bsky.social.
Thanks to @wellcometrust.bsky.social for hosting the meeting where these ideas were spawned.

Out now: our new study shows that climate change caused nearly 1,700 heat-related deaths in Zürich over 50 years.

We assessed the effects of changing vulnerability to heat, heat-mortality within and outside of heatwaves, and the contribution of individual companies' emissions to heat deaths.

I heard that ICE sent about 10% of the firefighters home, many of whom were from tribal nations. Fire containment is down to 10% and has been burning for two months.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report.
This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.

Example: refuting one sentence.
DOE CWG STATEMENT (second paragraph of section 2.1.1, page 3): “Piao et al. (2020) noted that greening was even observable in the Arctic.” COMMENT: This statement implies that the Arctic greening signal was caused by elevated CO2 , however that is not the scientific consensus. Piao et al. (2020) attribute the greening trend in the Arctic predominantly to growing season length driven by warmer temperatures (see also Y. Zhang et al., 2022). Piao et al. (2020) also note that this positive impact of increasing temperatures appears to have weakened over the past four decades, “suggesting a possible saturation of future greening in response to warmer temperature” (see also comment on greenness trends related to Section 2.1.1, first sentence of Page 4). It is also important to put Arctic greening more broadly into the context of the carbon cycle and other impacts. While above-ground plants may have displayed more leaf area over the past decades, rising temperatures also thaw permafrost and drive accelerated decomposition in highly carbon rich soils (Turetsky et al., 2020), a process which is expected to accelerate as climate continues to warm (Miner et al., 2022). Thus even with Arctic greening, high latitude terrestrial systems may become net carbon sources to the atmosphere, causing an amplifying feedback (Braghiere et al., 2023). Other risks to the Arctic linked to higher CO2 levels and rising temperatures are not mentioned in this report (Virkkala et al., 2025). The Arctic is warming at a rate of 2 to 3 times the global average, leading to thawing of permanently frozen soils (permafrost), with downstream impacts including loss of structural support for buildings and subsidence, threatening communities, roads, runways, and other assets across Alaska (Manos et al., 2025; University of Alaska Fairbanks Institute of Northern Engineering US Army Corps of Engineers Alaska District & Laboratory, 2019).

A few weeks ago I gave a presentation at the NASEM workshop on impact attribution. At 7.30am local time, clashing perfectly with getting 3 kids out the door. My middle one joined me and no doubt provided some entertainment for everyone. she loved pulling faces in the camera!

In fact, the in-room participants were very impressed with how well behaved she was. None had confidence that their kids would have been so polite and attentive. Your presentation was excellent and thought-provoking, as usual.

SpringerNature preprint server: claimed benefit is automatic updating of preprint to be consistent with final manuscript. Reality: return of manuscript reviews faster than time needed to post preprint, meaning missed opportunities to cite preprint in proposals and other submitted research.

Number of survey requests far exceeds available time. 11 requests in under 4 weeks, each up to 30 minutes to complete. Low response rates can potentially bias results. Consider whether another data collection method would provide more robust conclusions.

Very sad news: Linda Mearns passed away last night. A huge loss to her many friends and colleagues, and a tremendous loss to science. She research and insights improved the lives of millions. Her intelligence, humor, and obsession with uncertainty will always be remembered.
