These findings, published Monday in the journal Nature Climate Change, are alarming but also controversial. Other scientists say the study contains too many uncertainties and limitations to draw such firm conclusions and could end up confusing public understanding of climate change. Researchers say the results also suggest global temperature could overshoot 2 degrees of warming by the end of the decade. Changing that baseline would mean the world has already warmed at least 1.7 degrees (scientists say long-term global warming currently stands at between 1.2 to 1.3 degrees). Whatever the baseline for measuring global warming, what remains clear, experts say, is that the impacts will worsen with every fraction of a degree of warming.
