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.

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.

www.thelancet.com/journals/lan.... Priority needs to increase the validity, utility, and policy relevance of climate and health models include multinational centers of excellence, scenario elaboration, model inter comparisons, assessing adaptation effectiveness, strengthening research capacity.

Priority climate and health modelling needs

Climate and health modelling is necessary for improving understanding of the current and future distribution and timing of climate-related health risks. However, underinvestment in this area has limit...

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.

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.

On July 29, 2025, the Department of Energy (DOE) published a report from its Climate Working Group (CWG). This report features prominently in the EPA's reconsideration of its 2009 Endangerment Finding...

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).

In the US and interested in serving as an IPCC author for the 7th assessment report? This group is putting together nominations.

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.

Have you ever wondered if the global leadership on climate would be less depressing if we had more Luisas and fewer Elons? With gender equality backsliding everywhere, it’s super important to stress its role in addressing the climate crisis. A 🧵 on our new paper on gender equality & scenarios:

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.

The great global change scientist and advocate Bob Correll died yesterday. His contributions to US and international research and assessment can’t be overstated. His boundless energy, enthusiasm, and all encompassing friendship and extensive knowledge were inspiring. It was a privilege to know him.

Hello, I’m excited to use my first post here to share that I’ve been awarded an Emerging Leaders Prize in Climate Change and Health by the Medical Research Foundation! I’m grateful for the support from my group, colleagues & friends. Receiving the award at @royalsociety.bsky.social was a dream.
