A study published in Nature shows that climate change affects 80% of the world’s land area, where 85% of the global population lives.
According to the study, there is overwhelming evidence that climate change impacts are already observed worldwide in human and natural systems.
The study used the language model BERT to identify and classify studies on observed climate impacts, producing a comprehensive machine-learning-assisted evidence map, which researchers used to comb through over 100,000 published between 1951 and 2018.
These studies cover various fields from glaciology to agricultural science and marine biology to migration and conflict research. Evidence from these studies shows that climate change impacts are expanding. Climate literature has grown exponentially as well.
Study author Max Callaghan says in an interview that between 1951 and 1990, there was only 1500 climate-related research. Still, after five years since the last UN assessment, there were 75,000 to 85,000 studies which is a phenomenal increase.
