Climate Change Adds 41 Days of Dangerous Heat in 2024

A new report from World Weather Attribution (WWA) and Climate Central reveals that human-caused climate change added an average of 41 extra days of dangerous heat in 2024, posing severe risks to human health and ecosystems.

Rising Risks and Urgent Action

The study highlights that climate change intensified 26 out of 29 extreme weather events analyzed this year, which led to over 3,700 deaths and displaced millions globally. Events such as floods in Spain, hurricanes in the U.S., and droughts in the Amazon showcased the devastating impacts of global warming, compounded by human reliance on fossil fuels.

Friederike Otto, lead of WWA, called 2024 a "dangerous new era," noting that fossil fuel-induced warming has "never been clearer or more devastating." Otto emphasized the need to stop burning fossil fuels and accelerate the transition to renewable energy to prevent worsening disasters.

Record-Breaking Heat and a Call for Preparedness

This year is projected to be the hottest on record, with July 22 marking the hottest day in history. Scientists warn that if reliance on oil, gas, and coal continues, dangerous heat days will multiply, further endangering public health.

Ben Clarke of Imperial College London described the annual findings as a "failed scorecard," criticizing the lack of progress in cutting emissions and adapting to climate risks. Julie Arrighi of the Red Cross Climate Centre urged nations to adapt to warming temperatures and prioritize resilience in 2025 to safeguard lives and livelihoods.

Key Resolutions for 2025

The report outlines critical actions for the coming year:

  • Accelerate the transition away from fossil fuels.
  • Improve early warning systems and real-time reporting of heat-related deaths.
  • Increase international financial support for developing nations to build climate resilience.

As 2025 approaches, experts stress that decisive action is essential to halt the relentless cycle of heat waves, storms, and other extreme weather events driven by human-caused climate change.
