Why even a fraction of a degree can escalate climate change impacts

Even a small increase beyond the 1.5 degrees Celsius target set by global leaders could lead to drastic climate impacts, from intensified hurricanes and droughts to severe food shortages and mass migrations. Recent data shows nations are still off track from achieving this crucial threshold, raising alarms about the escalating risks. The COP31 summit highlighted just how marginal the difference is between manageable and catastrophic climate change effects, underscoring the urgency for immediate, aggressive action to curb emissions and limit temperature rises.
