What a Week’s Disasters Tell Us About Climate and the Pandemic
The hits came this week in rapid succession: A into the Indian megacity of Kolkata, pounding rains in the Midwestern United States, and on could be severe. It all served as a reminder that the coronavirus pandemic, which has killed 325,000 people so far, is colliding with another global menace: a fast-heating planet that acutely threatens millions of people, especially the worlds poor. makes extreme weather events more frequent and more intense. Now, because of the pandemic, they come at a time when national economies are crashing and ordinary people are stretched to their limits. Relief organizations working in eastern India and Bangladesh, for instance, say the lockdown had already forced people to rely on food aid by the time the storm, Cyclone Amphan, hit. Then, the high winds and heavy rains ruined newly sown crops that were meant to feed communities through next season. People have nothing to fall back on, Pankaj Anand, a director at Oxfam India, said in a statement Thursday. The worst may be yet to come. Several other climate hazards are looming, as the coronavirus unspools its long tail around the world. They include the prospect of heat waves in Europe and South Asia, wildfires from the western United States to Europe to Australia, and water scarcity in South America and Southern Africa, where a persistent drought is already deepening hunger. And then theres the locusts. Locusts. Abnormally heavy rains last year, which scientists say were made more likely by the long-term warming of the Indian Ocean, a hallmark of climate change, have exacerbated Higher temperatures make it more inviting for to places where the climate wasnt as suitable before and in turn, destroy vast swaths of farmland and pasture for some of the poorest people on the planet. While the risks are different from region to region, taken together, they should be seen as a sobering signal of what lies ahead for countries all over the world, a group of scientists and economists warned this month in . The impacts will not be equal, though, they added. They stand to exacerbate longstanding inequities, the experts said, and put specific populations at heightened risk and compromise recovery. All those hazards are made more frequent and intense by the accumulation of greenhouse gases in the atmosphere, which drives up temperatures on land and in the sea. The lockdowns around the world have resulted in a sharp drop in greenhouse gas emissions, but the decline has been nowhere near enough to shake loose the thick blanket of gases that already wraps the planet. And even if lockdown measures continued for the next several months, global carbon emissions would drop by between 4 to 8 percent from last year, according to a range of projections carried out by researchers, the latest of them last week. As punishing as that could be, socially and economically, it would not make a dent in overall warming trends. The impact of the accumulated warming is already felt by those who were in the eye of Cyclone Amphan this week: those who live in the delta regions of eastern India and Bangladesh, and who are at the mercy of intensifying heat waves, sea level rise, storm surges and super cyclones like this one. In rural Bangladesh, for example, the storm punched through embankments. Seawater ate the paddy fields. Mud and thatch homes collapsed. The slow burn of climate change has increasingly made it tough for many to make a living farming and fishing, as generations had before them; many workers had migrated to urban areas nearby to earn a living. The lockdown has put an end to that coping strategy. Migrant workers in India have been trying to head home in droves. Traditional ways of coping during storms are now more dangerous, too. Evacuating people to cyclone shelters has saved hundreds of thousands of lives in past storms, but aid workers now worry that the virus could spread quickly in shelters. In India, the city of Kolkata, which was pummeled by the cyclone, is repeatedly cited as one of the most vulnerable to the cumulative effects of climate change, all the more so because of poor urban planning. Its 14 million residents live cheek by jowl, and hunger still stalks many of them. The United Nations Development Program that global human development, which takes into account education, health and living standards, was set to decline this year for the first time since the concept of human development was introduced in 1990. The of the last few days, coming on top of the coronavirus pandemic, throw into sharp relief, said Corinne Le Quere, a climate scientist at the University of East Anglia in England, the perils of underestimating the impact of compounding risks. Economic recovery policies that governments enact after the pandemic lifts, she said, would impact the trajectory of emissions for decades to come. Reconstruction post Covid-19 should be shaped in a way that reduces our vulnerability, she said. That means both to prepare for extreme climatic risks, and to reduce emissions that underpin the climatic risks. is an international climate correspondent.
