New research finds natural climate feedbacks from thawing permafrost, intensifying wildfires, and greenhouse gas release from wetlands and lakes could amplify human-caused warming by 20–30% by 2100, adding about 0.2–0.4°C to global temperatures and not fully captured in climate models, potentially pushing projected warming toward 2.6°C with current policies.
A UIUC study shows decision-making signals arise in early brain regions such as the primary somatosensory cortex and are shaped by rapid top-down feedback, challenging the traditional bottom-up view and suggesting future AI that uses bidirectional processing could be more efficient and intelligent.
NASA scientists have observed an increase in rainy days and a longer rainy season in the Arctic and North Atlantic oceans from 1980 to 2016, with the most significant changes occurring in the North Atlantic. The rain is contributing to a feedback loop that amplifies warming and melting in the region, impacting sea ice, weather patterns, and global climate. These changes are driven by rising temperatures, which are causing snow to be replaced by rain, darkening the surface and leading to further warming. The Arctic's climate changes have far-reaching effects on weather patterns and temperatures in other parts of the world.
