Briefings

A recent study indicates that thawing permafrost, wildfires, and wetland warming could raise global temperatures by 0.2 to 0.4 degrees Celsius this century, significantly accelerating warming beyond current model projections. This feedback loop threatens to shorten the time needed for the planet to breach critical temperature thresholds like 1.5 and 2 degrees Celsius, potentially by up to 25%. The article highlights that major UN climate reports and current models fail to account for these effects, leaving a dangerous blind spot in global warming assessments.

Key points

• A September study in Environmental Research Letters found that permafrost thaw, wildfires, and wetland warming could drive global average temperatures up 0.2 to 0.4 degrees Celsius this century.
• This additional heat would add to the 2.6 degrees Celsius already expected by 2100, subjecting many cities to monthlong heat waves and exposing hundreds of millions to flooding.

Context

Climate change feedback loops are accelerating global warming beyond current models, with permafrost thaw and wetland warming potentially raising temperatures by 0.2 to 0.4 degrees Celsius this century. This study, published in Environmental Research Letters in September, synthesizes previous research to show that major UN climate reports and current models do not account for these effects, leaving a dangerous blind spot in global warming assessments.

Limitations

The study synthesizes results from previous papers but does not provide specific data on the exact timing of permafrost thaw or the precise geographic distribution of feedback effects. The article notes that while research groups are exploring mitigation strategies, the full impact of these efforts remains uncertain and unmeasured.
