US caused $10 trillion in climate damage since 1990, study finds

The United States has caused an estimated $10 trillion in global economic damage due to carbon emissions since 1990, according to a study published in Nature.
The research identifies the US as the largest contributor to climate-related economic losses, followed by China, which is estimated to have caused about $9 trillion in damage over the same period.
Led by Marshall Burke of Stanford University, the study examines how rising global temperatures linked to emissions have slowed economic growth worldwide. It highlights long-term impacts on productivity, public health, and overall economic output.
The findings show that while about a quarter of the losses tied to US emissions were felt domestically, poorer nations have borne the heaviest burden. India is estimated to have suffered losses of around $500 billion, while Brazil faced damages of approximately $330 billion.
Researchers said the economic harm has accumulated gradually over decades, creating a significant drag on global growth. The analysis does not account for all climate-related damages but establishes a measurable link between emissions and economic slowdown.
The study adds to ongoing calls from developing countries for financial support from wealthier nations to address losses caused by climate change, including those from extreme weather events such as floods, droughts, and heatwaves.
