At least 85 percent of the world's population has been affected by human-induced climate change

Researchers used machine learning to analyze more than 100,000 studies of weather events and found four-fifths of the world’s land area has suffered impacts linked to global warming

At least 85 percent of the global population has experienced weather events made worse by climate change, according to research published Monday in the journal Nature Climate Change.

After using machine learning to analyze and map more than 100,000 studies of events that could be linked to global warming, researchers paired the analysis with a well-established data set of temperature and precipitation shifts caused by fossil fuel use and other sources of carbon emissions.

These combined findings — which focused on events such as crop failures, floods and heat waves — allowed scientists to make a solid link between escalating extremes and human activities. They concluded that global warming has affected 80 percent of the world’s land area.

“We have a huge evidence base now that documents how climate change is affecting our societies and our ecosystems,” said lead author Max Callaghan, a researcher at the Mercator Research Institute on Global Commons and Climate Change in Germany.
