Humans have pushed the climate into ‘unprecedented’ territory, landmark U.N. report finds Researchers used machine learning to analyze more than 100,000 studies of weather events and found that four-fifths of the world’s land area has suffered impacts linked to global warming.These combined findings — which focused on events such as crop failures, floods and heat waves — allowed scientists to make a solid link betweenescalating extremes and human activities.
