The best case scenario for climate change just got worse

A climate change study published Wednesday shows it is "extremely unlikely" that Earth's climate sensitivity could be "low enough to avoid substantial climate change" with continued high emissions.Climate sensitivity is the measure of how susceptible Earth's climate is to human influence, per the study. In a 1979 report on sensitivity, it was estimated that if the carbon dioxide levels in Earth's atmosphere were to double compared to pre-industrial levels, temperatures could increase between 2.7
