Next week, more than 100,000 people will descend on New York City for more than 1,000 events during Climate Week. By one measure, that extraordinary turnout is a sign of success. By another, it raises an uncomfortable question: after years of summits, pledges and packed conference rooms, why does the climate crisis keep getting worse?
The last 11 years have been the 11 warmest on record. In 2024, the world experienced its first calendar year more than 1.5 degrees Celsius above preindustrial temperatures, and scientists expect the longer-term average to cross that threshold within the next decade. Just last month, a catastrophic glacier collapse and flood in Nepal killed more than 1,300 people and left thousands missing, with scientists concluding that climate change made the conditions behind the disaster more likely. In Europe, at least 35,000 more people died because of excess heat this past summer, driven by our quickly warming climate.
