Masson-Delmotte, climatologist: “When the global warming of 1.5 degrees is overcome, there are no mature solutions to go back”

This scientist stresses that every tenth of a degree of increase in the global average temperature increases extreme events in frequency, duration and intensity

For more than a year now, one of the main current climate change issues has been focused on double digits: 1.5 °C. Preventing the average temperature of the planet from exceeding this value is one of the two major safety limits set by the Paris Agreement to contain global warming, but there is no doubt that it will be exceeded. Although it has been considered lost for a long time, there is quite a bit of confusion about the fall of this negative milestone. Now, a new edition of Indicators of Global Climate Change (IGCC), in which 61 scientists from 17 countries participate, has reduced the margin left in the form of emissions to exceed this limit to just three years. Among these researchers is the French Valérie Masson-Delmotte (53 years old, Nancy), a climatologist at the Laboratory of Climate and Environmental Sciences of the Pierre Simon Laplace Institute in Paris, and until just two years ago one of the main responsible for the scientific assessments of the IPCC, the main panel of experts on climate change, as co-chair of group I.
