New research from the University of New South Wales suggests climate change could hurt the world economy much more than we thought. If the Earth’s temperature rises more than 3°C by 2100, global economic damage could reach up to 40%, not just 11% as older studies predicted.
This new model is different because it includes the way extreme weather in one country affects trade and economies in others. This shows how connected the world is—and how dangerous climate change can be for everyone.
Why It Matters
Rising sea levels could destroy cities. Droughts and floods could ruin crops. Diseases may spread. Many people may have to leave their homes. These problems would cost much more than the money needed to stop climate change now.
Studies say that for every $1 spent to stop emissions today, we could avoid $13 in future damages. Acting now is both smart and cheaper.
What Can Be Done?
Some financial groups are reducing their climate goals, which may allow more pollution. But others, like Aligned Climate Capital, are investing in clean technologies that also bring profits. Governments and individuals can help too.
People can support green businesses, donate to environmental causes, or make eco-friendly choices when shopping. Small actions can add up and make a big difference.
