Carrington"] published: 2026-05-18 updated: 2026-05-13 articles: 14 --- # The Docket > The Docket is a weekly publication about the decisions climate change is already putting in front of Americans: whether to buy the generator, whether the flood insurance is enough, whether to stay in the city you love. It follows the people making those choices now. It treats climate anxiety as a reasonable response to real conditions. It won't tell you what to do, but it shows the tradeoffs clearly.

Carrington]() · Published 2026-05-13 · Format: The Rate Changed A $34 billion coastal barrier. A city heat plan for a metro that already kills hundreds. Insurance policies priced to last year's losses. All calibrated to a warming rate of roughly 0.2°C per decade. In March 2026, a peer-reviewed study reported that rate has nearly doubled since 2015 — to approximately 0.35°C. The finding is genuinely contested, the cause unresolved. But the systems Americans live inside have design lives measured in decades, and every one of them is being built to specifications the science may have just invalidated. The chain that would update those specifications runs years behind the climate it describes. ### Why It May Be Worse Every climate projection carries a quiet assumption: that forests keep absorbing carbon, oceans keep storing heat, and natural cooling cycles keep doing their part. These buffers are baked into the models. They're part of why the numbers look the way they do. Recent research suggests several of those buffers are weakening simultaneously. Some were overestimated from the start. Others are degrading under the same warming they were expected to moderate. At least one may be approaching a threshold where it flips from sponge to source. No single finding here rewrites the picture. Together, they suggest the systems buying us time are losing capacity faster than the models account for. - **Climate Models Gave Plants Too Much Credit** — [Source]() — Published 2026-05-13 Tag: Carbon Buffer Natural nitrogen fixation, the soil process that fuels plant growth, was overestimated by roughly 50% in major Earth system models. Correcting it shrinks the projected CO₂ fertilization effect by 11%. One of the planet's assumed carbon buffers was never as strong as we built our projections around. - **The Land Stopped Absorbing What We Emit** — [Source]() — Published 2026-05-13 Tag: Land Sink Heat, drought, and wildfire drove the global land carbon sink to just 0.44 GtC in 2023, a sliver of its normal capacity. Northern Hemisphere forests have been net carbon sources since 2016. The ground beneath the models is, quite literally, giving back what it stored. - **Atlantic Circulation Collapse Could Unlock Stored Carbon** — [Source]() — Published 2026-05-13 Tag: Ocean Carbon A simulated AMOC shutdown flips the Southern Ocean from carbon sink to carbon source, releasing enough CO₂ to add 0.2°C of warming over centuries. Once triggered at current atmospheric concentrations, the collapse would be effectively irreversible. The ocean that absorbed our heat could start returning it. - **A Cooling Year That Wasn't Cool Enough** — [Source]() — Published 2026-05-13 Tag: Temperature Record 2025 was the second-hottest year on record during La Niña, the Pacific cycle that typically pulls global temperatures down. The underlying warming signal has grown so large that the planet's strongest natural coolant can no longer drag temperatures below recent records. - **Wildfires Now Accelerate the Warming Feeding Them** — [Source]() — Published 2026-05-13 Tag: Fire Feedback Burning hours across North America are up 36% over fifty years. Fire-prone days up 44%. Each blaze releases stored carbon and destroys the forests that would have reabsorbed it. At 1.5°C of warming, this feedback loop is already visible in the data. Not projected. Measured. ### The Papers - **Global Warming Has Accelerated Significantly** — [Source]() — Published 2026-05-13 Foster G. & Rahmstorf S., Geophysical Research Letters, 53(5), March 2026. After statistically stripping El Niño, volcanic, and solar signals from five independent temperature datasets (NASA GISS, NOAA, HadCRUT5, Berkeley Earth, ERA5), the authors find warming has roughly doubled to 0.35°C per decade since 2015, clearing 98% statistical certainty across all datasets and both analytical methods. Most datasets now project the 1.5°C threshold breached before 2030. How robust is the method? The authors' own technique for removing natural variability is self-described as "decidedly imperfect," and scientific agreement on the acceleration finding is not universal. Why does this paper matter? Five-dataset convergence at this confidence level makes it the first peer-reviewed confirmation that the warming rate itself has shifted, not just the temperature. - **Overestimated Nitrogen Fixation Reduces Projected Land Carbon Sink** — [Source]() — Published 2026-05-13 Kou-Giesbrecht S. et al., PNAS, January 2026. A 23-author study comparing modeled nitrogen fixation against observational constraints finds CMIP6 Earth system models overestimate natural nitrogen fixation by more than 50%, inflating the projected CO₂ fertilization effect by approximately 11%. The land carbon sink, in short, is a weaker emissions buffer than current IPCC projections assume. Remaining carbon budgets under Paris targets may be correspondingly smaller. What's the structural problem? Climate models informing international policy systematically overstate how much plant growth absorbs emissions, biasing carbon budgets in one direction. Any offset? Agricultural nitrogen fixation, up 75% in two decades, partially compensates in the total budget. The natural sink, though, is the one policy treats as reliable. ### One Aquifer, Faster - [Western Kansas Is Planning for 2070. The Aquifer Math Now Points to 2055.]() — Published 2026-05-13 The number governing western Kansas water policy is 2070, when the Ogallala Aquifer is projected to hit 70 percent depletion. That projection, from the USDA's 2024 synthesis, assumes a continuation of historical drawdown trends measured during decades of warming at roughly 0.2°C per decade. The documented rate is now 0.35. ### Keep Reading - **Warming at 0.35°C Per Decade Now: Rahmstorf's Team Puts a Number on What 2024 Felt Like** — [Source]() — Published 2026-05-13 The Potsdam team's own framing of the acceleration finding, and what the revised rate implies. - **A La Niña Year Hotter Than the Strongest El Niño on Record** — [Source]() — Published 2026-05-13 2025 should have been cooler. It wasn't. Yale's overview captures the baseline shift underneath. - **Forests and Grasslands Fix Half the Nitrogen We Assumed.
