U.S. Forest Service unveils extensive closures of research facilities Cost-cutting move is expected to cause resignations and turmoil

What will happen to the 82 USFS experimental forests around the country? Many sites have decades-long experiments that are tracking how forests are changed by timber harvesting practices and climate change. As I say here, “you can't just pick up an experimental forest site and move it to SLC.”

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

I had a time series of mangrove carbon export for many years, and then it was hit by Hurricane Irma. The result is some pretty interesting science.

People want mangroves to take up more CO₂ from the atmosphere, but with climate change and more extreme storms, they're probably going to do less. 🧪

Slowly, Slowly, ‘Darwin’s Finches of the Snail World’ Return From Near Extinction

There is No Scientific Justification to Revoke the Endangerment Finding The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org

I am a climate scientist and this is correct.

As the planet warms, storms like the one today are getting stronger… and as the Arctic is warming twice as fast as the mid latitudes, it increases the risk of the “freezer door” swinging open.

abstract: A recent report released by the U.S. Department of Energy concludes that U.S. tide-gauge data in aggregate provide no evidence for relative sea-level (RSL) acceleration above the historical mean trend. However, that conclusion rests largely on cursory analysis of a small number of tide-gauge records that are known to be unrepresentative of large-scale RSL behavior. Here I analyze all long active tide-gauge RSL data records on the contiguous U.S. (CONUS) coast to make a comprehensive estimate of spatially averaged RSL changes over the CONUS (CONUS RSL) during the past 125 years. I find that long-term rates of CONUS RSL rise doubled in the past century, from about 1.7 mm in 1900 to roughly 4.3 mm in 2024, and that recent rates are higher than the longterm historical mean rate since 1900, which is approximately 3.0 mm . That is, CONUS tide gauges give obvious evidence of RSL acceleration, which is likely related to ongoing climate change.

Am I surprised to see papers coming out that specifically debunk the DOE Climate Working Group report? I guess not, the community was pretty pissed.

Climate change risks on key open marine and coastal mediterranean
ecosystems

Abed El Rahman Hassoun1, Meryem Mojtahid, Mohammad Merheb, Piero Lionello, Jean-Pierre Gattuso & Wolfgang Cramer
Mediterranean open marine and coastal ecosystems face multiple risks that impact their unique biodiversity, with climate change representing a major ongoing threat. While these ecosystems are also under pressure from non-climatic anthropogenic drivers (e.g., overfishing, pollution), this study primarily focuses on risks related to climate change. To assess these risks and evaluate their confidence levels, we adopt the scenario-based approach of the Intergovernmental Panel on Climate
Change (IPCC), relying on a review of literature projecting changes in Mediterranean Sea ecosystems.
The main drivers of environmental change are sea level rise, ocean warming and acidification. Similar to global conditions, all Mediterranean ecosystems face high risks under all climate scenarios, with coastal ecosystems being more strongly impacted than open marine ecosystems. For these coastal ecosystems, risk levels are expected to become very high already once global warming exceeds 0.8 °C with respect to the 1976–2005 period. A few Mediterranean ecosystems (e.g., coralligenous and rocky coasts) are relatively more resilient compared to others, probably because of their long evolutionary history and the presence of a variety of climatic and hydrological conditions. However, high-emission scenarios in specific sub-basins, in addition to acidification impacts, could reduce this resilience, decreasing both habitat extent and ecosystem function dramatically. Overall, due to the higher observed and projected rates of climate change in the Mediterranean, compared to global trends, for
variables such as seawater temperature and pH, marine ecosystems (particularly coastal) are projected to be under higher risks compared to the global ocean.
