Climate change caused by humans could have caused droughts as far back as 1900, according to a study.
They said more research is needed to prove whether greenhouse gas emissions cause droughts, and to explore the interplay between this phenomenon and aerosols. Benjamin Cook of the NASA Goddard Institute for Space Studies and Columbia University's Lamont-Doherty Earth Observatory, who co-authored the study, said:"The big thing we learned is that climate change started affecting global patterns of drought in the early 20th century. We expect this pattern to keep emerging as climate change continues."
Professor John Quiggin, Australian Laureate Fellow in Economics at the University of Queensland, commented the research adds to evidence suggesting climate change driven by increased greenhouse gases, including carbon dioxide, likely increases the frequency of droughts.
Climate change is currently taking place at Mars. You know that? What is the cause?
