2015 UN treaty under which nearly 200 nations pledged to limit global warming to well below 2°C, pursuing 1.5°C, via national emissions targets.
Global Climate and Health Alliance scorecard of 132 countries says the EU, China, Brazil and the UK mention health but lack the targets to protect it. Only five countries set black carbon targets, the alliance says.

A group led by Saudi Arabia and Russia, including India and China, is pressing the IPCC to move its seventh report to 2029, the Guardian reported. The report was timed for the Cop33 summit in 2028, so a slip would put it after the meeting.
Reality
Nearly three years of debate have left the IPCC's 195 member states without publication dates for the next assessment. Under the chairs' proposal, approval would come about two months before the November 2028 Paris stocktake.
Reality
Copernicus put August 2026 at 16.96C, a hundredth of a degree above July 2023 and inside its own uncertainty, so it calls the month a tie. The clustering of the record months is the firmer finding.

Researchers led by the University of Twente conclude in a KIN-commissioned report that no available carbon removal technology is ready for Dutch scale-up. They want rules on land, water, energy and fair burden-sharing in place before any national push toward deployment.
Reality
Researchers writing in Nature Geoscience give at least 89% odds that the strictest Paris path costs Antarctica less ice by 2100 than very high emissions. For coastal planners, that puts part of Antarctica's future contribution to sea level within reach of emissions policy.
Reality
Researchers screening hundreds of thousands of simulated futures in Nature Geoscience find Antarctica loses ice on net this century, even at 1.5C of warming. In the runs that survive, extra snowfall does not outweigh the loss, so Antarctica adds to sea-level rise this century.
Reality
UNEP now accepts the overshoot and describes a way back to 1.5C by 2100 that needs global emissions halved by 2035 and then removal running at a scale one outside researcher puts at 100,000 times today's.

Both reports released this month treat passing 1.5°C as the working assumption, and the account of them from one of the Canadian authors gives the 5°C national figure without naming an emissions scenario or a range.

Attribution science usually asks what two centuries of fossil fuel burning did to a heat wave. A Stanford group asked what the ten years since the Paris Agreement did, and found a measurable answer in Europe's worst recent heat.

The annual Planetary Health Check counts seven of nine boundaries transgressed, ocean acidification among them since 2025, and puts carbon dioxide at 426 parts per million against 280 before industrialisation. More than 60 scientists signed it.

Antonio Guterres leaves at the end of the year after spending his final two years on cost cuts, and the three named candidates to replace him would take over a system whose revenue grew 85 percent between 2010 and 2022.

Bernardo Flores says warming has already reached the first of those two conditions, and the El Nino now strengthening is likely the strongest on record, arriving in a basin where at least 40% of the forest is estimated to be degraded.

A phys.org explainer sets the Bonn Challenge's 350-million-hectare target against dryland ecology, where planting trees can cut river flow and darken bright ground enough to cancel part of the carbon gain.

Climate Analytics and the Potsdam Institute treat the 1.5C breach as settled and model how long the overshoot lasts. Their Australian pathway needs a 55% cut on 2005 levels by 2030, where current policy delivers 43%.
Reality
A new model has the world's largest carbon sink turning into a source once concentrations start falling, with two heat-driven feedbacks amplifying the outgassing for centuries after net zero and capping what removal delivers.

Melbourne and ANU researchers mapped inundation onto property registers under a mid-range warming scenario, then held storm intensity constant and left erosion out, which is why $855 billion is a floor.

UC Santa Barbara and Tsinghua authors argue in Science that the first plastics treaty text needs standardized labeling, measurement practices and national data repositories. Their paper feeds a workshop in Geneva on Sept. 16-17.

Rahul Ghosh's "pragmatic transition" is a ratings agency describing an underwriting rule: Asian frameworks safeguard transition assets more than Europe's do, so one cash flow can carry two costs of capital.

Rio Tinto's disclosed central case runs to 2.1C-2.3C by 2100, above the peak warming scientists say still allows a return to safe levels. Its future production plans, the same filing says, are unchanged.
