Oxford Study: Extreme Heat to Engulf 40% of Humanity by 2050, India Among Worst-Hit

• A new Oxford University study warns that a 2-degree Celsius global temperature rise will double extreme heat exposure by 2050, affecting nearly 4 billion people.
• The research, published in Nature Sustainability, indicates that 41% of the world's population could face severe heat stress if warming exceeds 2 degrees Celsius.
• India, Nigeria, and Indonesia are identified as most vulnerable due to large populations and limited cooling access, with Pakistan, Bangladesh, and the Philippines also at high risk.
• Colder countries like Canada, Russia, and Finland are also vulnerable due to infrastructure designed for cold climates, making them ill-prepared for sudden heat increases.
• Scientists emphasize urgent adaptation strategies, including redesigning infrastructure and achieving net-zero emissions, to prevent irreversible climate catastrophe.

Why It Matters: Extreme heat threatens 40% of humanity by 2050, with India severely impacted; urgent action is critical.
