The natural disasters of 2022 claimed thousands of lives, 44 million people displaced and damage equal to more than 200 billion dollars. This is almost half of the total damage caused by extreme weather events in Europe over the past 40 years. But the most dramatic news is that these estimates are at discountand because not all countries keep track of human losses and displaced persons, and because the economic estimates are based only on losses covered by insurancetherefore the real financial costs are certainly much more expensive.
The report reveals it Counting the cost 2022 by Christian Aid, a UK-based aid organisation, which identified i 10 most expensive natural disasters of the year, influenced by the climate crisis, and others 10 of the most devastatingin human and environmental terms. In this article we have merged the two rankingsrestoring order chronological the worst in absolute terms.
In the list, three events that exceeded the rank of natural disaster were excluded, becoming stable atmospheric phenomena of continuous duration. It’s about the Drought which now hit almost continuously the Brazilthe China and the countries of the Horn of Africa. According to the report data, the first two provoked at least $12 billion in damages, but there are no precise sources to estimate the economic impact of the drought in the Horn of Africa. On the contrary, the effects it has on humans are well known, having involved approx 36 million people.
These natural disasters highlight the need for aclimate action more incisive and ambitious, as well as a higher recruitment of responsibility by the world’s major polluters, who have discharged the effects of their own short-sighted choices on those countries that did not help trigger the climate crisis. However, according to Climate Action Tracker, an independent research group that monitors government actions to reduce greenhouse gases, the climate goals of all the countries that pollute the most are “insufficient“ to meet the goals of the Paris Agreement and keep the rise in global temperatures below 1.5 degrees.
But not limiting carbon emissions will only lead to new ones chain reactionswhich will make it even worse climate crisis increasing global warming. An example of these chain reactions is easily observed by considering the effects of global warming at the two poles of the planet.
On March 18, 2022, at the same time, both in Antarctica that inArctic have registered record temperatures47 and 30 degrees higher than normal. As a result of these heatwaves, the ice shelf known as the Conger in Antarctica has collapsed and melted into the sea, while temperatures in the Arctic are thawing the permafrosta layer of ground frozen for tens of thousands of years.
Trapped in ice, they are found huge amounts of carbon which are released when the permafrost melts. Once in the atmosphere they will contribute to global warming even worse, by melting permafrost even faster, in an almost unstoppable cycle unless carbon emissions are drastically reduced before it is too late.
