If average warming crosses 1.5 degrees Celsius, even humanity’s best adaptation efforts could falter, the report warns. The costs of protecting coastal communities from sea level rise can be beyond the means of many countries. Rachel Bezner Kerr, an agricultural expert at Cornell University who contributed to the report, said that in some areas, including parts of North America, livestock and outdoor workers may be able to. faced with increased levels of heat stress that made farming increasingly difficult.
“Beyond 1.5, we will not be managing on many fronts,” said Maarten van Aalst, Director of the Red Cross’s Red Crescent Climate Center and another author of the report. “If we don’t make changes now to the way we deal with physical infrastructure, and the way we organize our society, that’s going to get worse.”
Poor countries are more exposed to climate risks than rich nations. Between 2010 and 2020, droughts, floods and storms killed 15 times more people in vulnerable countries, including Africa and Asia, the report said. richest.
That disparity has sparked a fierce debate: which industrialized nations are most responsible for greenhouse gas emissions. debt to developing countries. Low-income countries want financial help, both to defend against future threats and to compensate for the damage they cannot avoid. The problem will make headlines when governments meet for the next United Nations climate summit in Egypt in November.
“Climate change is the ultimate injustice,” said Ani Dasgupta, president of the World Resources Institute, an environmental group. “Those with the fewest resources, those least responsible for the climate crisis, bear the brunt of the climate impacts.” He added, “If you don’t live in a hotspot, imagine instead a roof blown off, a village flooded with saltwater, crops fail, jobs lost, meals skipped. – all repeated. ”
The report, approved by 195 governments, states that risks to people and nature increase with every fraction of warming.
At the current level of warming, such as the ability of a person to feed himself is becoming tense. While the world is still producing more food each year, thanks to improvements in farming and crop technologies, climate change has begun to slow growth, the report says, a remarkable trend. fear of putting future food supplies at risk as the world’s population has skyrocketed in the past. 8 billion people.
