Climate Change Intensified Summer Heat, Leading to Widespread Impacts and Deaths

Climate Change and Summer Heat

• 🌍 Human-caused climate change significantly increased risky and unnatural heat this summer, affecting nearly two billion people globally.
• 📈 A report by Climate Central found that 183 countries experienced at least 30 days of higher temperatures influenced by climate change.
• 🇺🇸 In the US, 32 cities recorded over 30 additional days of heat risks.

Global Impacts of Increased Heat

• 📊 Every day this summer, one in five people worldwide endured temperatures strongly influenced by climate change, totaling 1.8 billion people.
• ⚠️ Nearly one billion people faced an extra 30 days or more of risky heat, defined as days hotter than 90% of historical local temperatures.
• 🔥 The increased heat contributed to a severe wildfire season in Europe and Canada, and catastrophic flooding in the US, including deadly flash floods in Texas.

Methodology and Findings

• 🔬 Climate Central compares computer models, one with greenhouse gases and one without, to quantify the influence of climate change.
• 💡 Removing greenhouse gases from models revealed that events like extreme heat and associated disasters would not have occurred without human emissions.

European Heatwave Deaths

• 💔 A separate study found that climate change intensified summer temperatures in Europe, leading to over 16,000 additional deaths.
• 👵 The study, focusing on 1850 European cities, attributed 68% of heat-related deaths to climate change, with individuals over 65 being the most vulnerable.
• ⛽ Researchers emphasize the need to protect people from heat and rapidly transition away from fossil fuels.
