WHAT THE EVIDENCE SAYS
An Amazon-wide analysis found high-temperature extremes and temperature-linked water deficits changing much faster than central climate trends. The 95th percentile of maximum temperatures in the driest period increased by 0.49 °C per decade, compared with 0.21 °C per decade for mean annual temperature. More than 700,000 km² of central-north Amazonia experienced increases in extreme dry-season temperatures of at least 0.75 °C per decade.
WHY IT MATTERS / OUR READ
Average conditions can be a poor ecological proxy when persistence is governed by extremes and thresholds. Monitoring and adaptation that track only mean warming may miss places where organisms, fire regimes and water balance are being pushed much faster toward limiting conditions.
CAVEATS / UNCERTAINTY
This is a regional gridded analysis of climatic extremes. It identifies accelerating exposure and areas of concern; it does not by itself demonstrate ecosystem collapse or a uniform biological response across Amazonia.
