“Planetary emergency”: tipping points in the earth's climate are coming sooner than expected

To minimize the risk of this, global warming would have to stay as close as possible to the 1.5 degree target by reducing carbon dioxide emissions to zero. However, it will take at least 30 years to create a CO2-Achieve neutrality, says Richardson. "That is our most optimistic estimate of the time."

"I don't think people realize how little time we have," said Owen Gaffney, a global sustainability analyst at Stockholm University's Stockholm Resilience Center. “In a decade or two we will reach 1.5 ° C. And since we only have three decades to get away from the CO2 getting down is clearly an emergency situation, ”says Gaffney, another co-author of the comment.

"Without emergency response, our children are likely to inherit a dangerously unstable planet," he said in an interview.

The economy is a priority

Meanwhile, a UN report shows that the US, China, Russia, Saudi Arabia, India, Canada, Australia and other countries plan to produce around 120 percent more fossil fuels by 2030. The same governments have pledged to limit global warming to 1.5 ° C - but seem more concerned about their economic growth.

No amount of economic cost-benefit analysis can help us now that the very existence of our civilization is at risk, write Gaffney and his co-authors. Governments rely heavily on the advice of economists, but with a few exceptions, the profession has done mankind a pretty disservice by not factoring in climate change in its research, Gaffney says. Only a fraction of the articles and studies in business journals deal with climate change, he notes.
