Temporarily exceeding the 1.5°C limit would have irreversible consequences
Research published in Nature analyses future scenarios in which the 1.5°C temperature limit set in the Paris Agreement would be temporarily exceeded, assuming that temperatures could be lowered in the long term by reducing carbon dioxide emissions using different techniques. The authors stress that exceeding this threshold would have irreversible consequences for the Earth system in key areas such as biodiversity, sea level and carbon stocks. ‘Only rapid, short-term emission reductions are effective in reducing climate risks,’ they stress in the paper.
