July 2023
Dartmouth College

Introduction
Imagine a world where sweltering heat does more than just make you sweat; it's costing the global economy trillions! Dartmouth College researchers have uncovered how severe heat waves, supercharged by climate change, have already drained trillions from the world's wallet since the 90s. And guess what? The poorest, least polluting countries are bearing the brunt. This eye-opening study isn't just about numbers; it's a wake-up call for immediate action to cool down these costly temperatures. Dive into the details and discover why beating the heat is about more than just staying comfortable—it's crucial for our global economy!

Feeling the Heat - The Economic Burn of Global Warming
Imagine a world where the scorching heat not only makes it unbearable to play outside but also costs the global economy trillions of dollars, hitting hardest at those who can least afford it. This isn't a distant nightmare; it's happening right now. Heat waves, supercharged by human-caused climate change, are not just about getting an extra scoop of ice cream to cool down. They're about the livelihoods of millions, especially in the world's poorest regions, taking a massive hit. The intensifying heat waves since the early 1990s have led to a staggering economic loss of $16 trillion due to their impact on human health, productivity, and agriculture. This topic is not just about numbers on a page; it's about understanding the profound implications of our actions on the planet and on each other. It's about realizing that climate change isn't just an environmental issue—it's a human one that affects us all, no matter where we live. This might sound daunting, but it also opens up a world of opportunity for you to make a difference, whether through innovative solutions, policy advocacy, or simply by being informed and spreading the word.
