Global warming could make survival in the tropics impossible: study

[ad_1] Limiting global warming to the targets proposed in the Paris Agreement could prevent tropical regions from reaching temperatures that are beyond human tolerability, according to a new study project. Researchers estimate that if countries manage to cap warming at 1.5 degrees Celsius above pre-industrial levels, the tropics will be spared from temperatures exceeding the … Read more
