Bulgaria: Biggest Weather Disasters Cost Around USD 150 Billion in 2020

The world’s 10 costliest weather disasters of 2020 reached insured damages worth 0bn, claimed at least 3,500 lives and displaced more than 13.5 million people. This is more than 2019 and reflects a long-term impact of global warming, according to a new report.

From Australia’s out-of-control wildfires to a record number of Atlantic hurricanes through November, the true cost of the year’s climate-enhanced calamities was in fact far higher because most losses were uninsured.

According to the annual tally from the charity Christian Aid, entitled Count the cost of 2020: a year of climate breakdown, the burden fell disproportionately on poorer nations.

Only 4% of economic losses from climate-impacted extreme events in low-income countries were insured, compared with 60% in high-income economies, the report said, citing a study last month in The Lancet.
“Whether floods in Asia, locusts in Africa, or storms in Europe and the Americas, climate change has continued to rage in 2020,” said Christian Aid’s climate policy lead, Kat Kramer.

Extreme weather disasters, of course, have plagued humanity long before man-made global warming began to mess with the planet’s climate system.

But more than a century of temperature and precipitation data, along with decades of satellite data on hurricanes and sea level rise, have left no doubt that Earth’s warming surface temperature is amplifying their impact.
Massive tropical storms – variously known as hurricanes, typhoons and cyclones – are now more likely, for example, to be stronger, last longer, carry more water and wander beyond their historical range.
2020’s record-breaking number of named Atlantic hurricanes – with at least 400 fatalities and bn in damages – suggest the world could see more such storms as well.

The World Meteorological Organization (WMO) had to use Greek symbols after running out of letters in the Latin alphabet.
Intense summer flooding in China and India, where the monsoon season brought abnormal amounts of rainfall for the second year running, are also consistent with projections on how climate will impact precipitation.

Five of the most costly extreme weather events in 2020 were related to Asia’s unusually rainy monsoon.
The 2020 flood was one of the worst in the history of Bangladesh, more than a quarter of the country was under water.
Wildfires that scorched record areas in California, Australia and even Russia’s Siberian hinterland, much of it within the Arctic circle, are also consistent with a warmer world, and a predicted to get worse as temperatures climb.

The planet’s average surface temperature has gone up at least 1.1 degrees Celsius on average compared to the late 19th-century, with much of that warming occurring in the last half-century.
The 2015 Paris agreement enjoins the world’s nations to collectively cap global warming at “well below” 2C, and even 1.5C if feasible.

A landmark report in 2018 from the UN’s IPCC climate science advisory panel showed that 1.5C is a safer threshold, but the likelihood of staying below it have grown vanishingly small, according to many experts.
Ultimately, the impacts of climate change will be felt via the extremes, and not average changes.

If the growing frequency and intensity of natural weather disasters is consistent with the modeling projections, the new field of attribution science is now able to put a number on how much more likely such an event is due to global warming.
The unprecedented wildfires that destroyed 20% of Australia’s forests and killed tens of millions of wild animals in late 2019 and early 2020, for example, were made at least 30% more likely, according to research by the University of Oxford’s environmental change institute.
