The short version

  • Independent climate monitoring agencies report that recent global temperatures reached near-record levels, while oceans hit their highest average surface temperatures since 1979.
  • The severe heat caused an estimated 14,000 heat-related deaths in Germany, €180 billion in lost EU gross domestic product, and major agricultural losses across Europe and the United States.
  • Attribution studies indicate that human-caused climate change significantly increased the likelihood of summer wildfires in Spain and France.
  • Low river levels in Europe and widespread drought in the United States continue to threaten supply chains, crop yields, and water supplies.
