  1. Estimated annual catastrophe losses rose sharply in nominal dollars from 2020 to 2025, but much of that increase is driven by greater exposure — more construction and higher construction prices — rather than clear evidence of climate-driven loss growth.
  2. When losses are measured as a share of global GDP, weather-related disaster losses have not increased since 1990 and were below the long-term average in 2025.
  3. Different firms produce different loss totals and insured-loss numbers are more reliable than total loss estimates; to detect climate signals you should look at climate data rather than economic loss data, and keeping disaster impacts low will require continued effort.

  1. 2025 had one of the lowest global death rates from extreme weather on record, at under 0.8 deaths per million people.
  2. This low toll is part of a long-term decline: death rates from extreme weather have fallen dramatically since the 1960s as better science, technology, policy, and greater wealth reduced vulnerability.
  3. Progress doesn’t eliminate risk—large, deadly disasters can still occur, and the data have limits (older undercounts and exclusion of extreme temperature impacts), so continued preparation and careful tracking are essential.

  1. The global sea surface temperatures hit a new modern record high, which is a serious concern for climate change.
  2. Research suggests that the Atlantic overturning circulation (AMOC) is moving towards a tipping point, which could have catastrophic consequences for Europe's climate.
  3. It is crucial to appreciate and protect nature's beauty while also being mindful of the urgent climate concerns and potential tipping points.

Climate Change API

🔬 Science Climate Data
  1. The Climate API provides high-resolution climate data from the IPCC 6th assessment report, showcasing effects like temperature increases, extreme temperatures, and melting of Arctic sea ice.
  2. High-resolution climate models allow for more accurate regional climate change predictions, aiding in studies on the impacts of climate change on a smaller scale.
  3. The Climate API offers daily climate data from 1950 to 2050, enabling users to calculate climate indices and make projections like crop yield, pest infestation, and more.

July 2024 Becomes Second-Hottest Month on Record, Narrowly Missing Top Spot

The Climate Historian • 0 implied HN points • 08 Aug 24
🌞 Climate & Environment Climate Data
  1. July 2024 was the second hottest month ever recorded, just a tiny bit cooler than July 2023. This means our planet is still getting warmer.
  2. Global temperatures are about 1.48°C higher than pre-industrial levels, showing clear signs of climate change. These changes will keep happening unless we reduce greenhouse gas emissions.
  3. Temperature changes were felt everywhere, with Europe experiencing a notably hot month, while some areas like Antarctica and parts of the U.S. saw cooler temperatures.
