The report warns that if average warming exceeds 1.5 degrees Celsius, even the best human efforts to adapt could falter. The cost of defending coastal communities against rising seas can exceed what many countries can afford. In some areas, including parts of North America, livestock workers and outdoor workers may experience increased levels of heat stress that is making farming increasingly difficult, said Rachel Pezner Kerr, an agricultural expert at Cornell University who contributed to the report.
“After 1.5, we won’t be dealing with many fronts,” said Martin van Aalst, director of the Red Cross Red Crescent Climate Center and another author of the report. “If we don’t implement changes now in terms of how we approach physical infrastructure, but also how we organize our communities, it’s going to be bad.”
Poor countries are more exposed to climate risks than rich countries. Between 2010 and 2020, droughts, floods and storms killed 15 times as many people in highly vulnerable countries, including those in Africa and Asia, than in the richest countries.
This disparity has sparked a contentious debate about which industrialized countries are most responsible for greenhouse gas emissions The Developing Countries. Low-income countries want financial assistance, to defend against future threats and to offset the damage they cannot avoid. case will Be the focus when governments gather at the next UN Climate Summit in Egypt in November.
“Climate change is an absolute injustice,” said Annie Dasgupta, president of the World Resources Institute, an environmental group. “The people with the fewest resources, and the least responsibility for the climate crisis, bear the brunt of the climate impacts.” He added, “If you don’t live in a hot spot, instead imagine a roof flying away, a village well flooded with salt water, a failed crop, a job lost, a meal skipped — all over and over again, over and over again.”
The report, which has been approved by 195 governments, shows that the risks to humans and nature are accelerating with each additional fraction of the degree of warming.
At current levels of warming, for example, Mankind’s ability to feed itself Already under pressure. While the world continues to produce more food each year, thanks to improvements in agriculture and crop technology, climate change is beginning to slow the growth rate, an ominous trend that puts future food supplies at risk as the world’s population grows, the report said. 8 billion people.
