Siberian permafrost thaw accelerates methane emissions, study finds doubling over decade¶
Scientists from the University of Leicester and National Centre for Earth Observation report that methane emissions from thawing Siberian permafrost have doubled over the past ten years, demonstrating the accelerating feedback loop of Arctic warming. This finding underscores a critical climate tipping point where warming triggers increased greenhouse gas release from frozen soils.

Australia confronts climate adaptation crisis as repeated disasters outpace preparedness¶
An extensive report published in early August 2026 documents how Australian communities are struggling to adapt to climate-linked disasters including floods, droughts, and heat extremes, with governments failing to adequately fund or implement adaptation measures. The analysis reveals widespread property devaluation, population displacement, and recognition that current defenses are insufficient for projected future impacts.
- Greater Shepparton flood (October 2022) caused property values to collapse ~$90,000 on same street
- Darwin temperatures rising; doctor reports city will be 'unliveable' in 50 years
- Tweed Shire approved 175 government buybacks of flood-vulnerable homes
- Multiple floods in Tweed Shire: 2017, 2022, 2024, plus ex-tropical cyclone Alfred 2025
- Adaptation funding and planning consistently lag behind disaster frequency
