I am a mom and scientist begging everyone to look closer at the muck. We’ve been conditioned to see wetlands as wastelands. But three decades of research, I see a fiercely defiant wilderness. The boreal mire is a dynamic carbon-trapping vault that in some places has outlasted ice ages. 1/

This is so, so well-articulated.
People call this friction "grunt work." Schwartz uses exactly that phrase, and he's right that LLMs can remove it. What he doesn't say, because he already has decades of hard-won intuition and doesn't need the grunt work anymore, is that for someone who doesn't yet have that intuition, the grunt work is the work. The boring parts and the important parts are tangled together in a way that you can't separate in advance. You don't know which afternoon of debugging was the one that taught you something fundamental about your data until three years later, when you're working on a completely different problem and the insight surfaces. Serendipity doesn't come from efficiency. It comes from spending time in the space where the problem lives, getting your hands dirty, making mistakes that nobody asked you to make and learning things nobody assigned you to learn.

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. agupubs.onlinelibrary.wiley.com/doi/10.1029/...
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.

title, authors and abstract of the paper

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.
