Climate Change's Economic Impact: Global GDP Losses and Vulnerable Sectors
Climate change is causing big problems for the world's economy.
It's making weather events like hurricanes, floods, and heatwaves more frequent and severe, which damages infrastructure, reduces farm yields, and hurts workers' productivity.
Countries like India, China, and the least developed countries are especially vulnerable.
For example, India could lose a lot of its GDP by 2070 if things don't change.
The world is trying to figure out how to adapt and mitigate these effects, but it's a big challenge.
Some people think we should focus on economic growth first, while others say we need to prioritize climate action to prevent even bigger problems in the future.
Climate change is causing significant economic losses globally, with direct losses averaging over $110 billion annually between 2015 and 2024.
India is particularly vulnerable, with a projected 24.7% GDP loss by 2070 due to climate change.
Climate-related events in India, such as floods, cyclones, and heatwaves, have affected 1.3 billion people and caused over $170 billion in economic losses.
India has reduced its emissions intensity by 36% between 2005 and 2020 and aims for a 47% reduction by 2035.
Climate change impacts various sectors, including agriculture, manufacturing, and infrastructure, and could reduce India's GDP growth by 0.5 to 1 percentage point annually if adaptation remains insufficient.
