New studies highlight climate feedback risks as emissions policies face pressure

New research and policy assessments are drawing attention to rising climate risks, including warming-driven emissions, expanding electricity demand and uneven government action.
A synthesis published in *Environmental Research Letters* estimated that carbon dioxide and methane released by thawing permafrost, worsening wildfires, warmer inland waters and changing wetlands could add 0.2C to 0.4C to global temperatures this century. MIT Technology Review reported that major models used in UN climate assessments do not incorporate all of these feedback effects. More than 20 research teams are now comparing models in an effort that could inform the UN’s next major assessment in 2029.
In the United States, a Sierra Club analysis said planned data centers and associated fossil-fuel infrastructure could raise power-sector carbon dioxide emissions by 42% between 2025 and 2030, although the outcome depends on which projects are built and how they are powered. An earlier academic study projected a smaller increase relative to a scenario without data-center growth.
Climate Action Tracker separately estimated that Canada’s current policies would reduce emissions 14% below 2005 levels by 2030. The group accused Prime Minister Mark Carney’s government of weakening climate policy.
Other research found that unusually hot weather before elections was associated with greater concern about climate change and increased support for Green parties across 25 European countries from 2012 to 2022. Meanwhile, scientists studying Tibetan ice cores said high-altitude ice may preserve a climate record extending beyond 128,000 years, potentially the oldest recovered from that region.

WHAT THE EDITOR DID
The second model checked the writer's draft against the same sources and changed it before publication. Struck words were in the draft; underlined words are its corrections.
WHAT IT FLAGGED editor revise: Delete the source-material commentary from the paragraph about Canada. - "the excerpt did not include a government response": This is commentary about the supplied source material rather than reporting from a source.
