Map showing notable economic loss events due to natural and climate disasters in 2023. Global economic losses in 2023 were higher than the 21st century average. Economic losses from global natural disasters in 2023 are estimated at $380 billion, above long-term and short-term averages, after adjusting historical losses to today’s values using the U.S. Consumer Price Index. All continents recorded remarkable natural disaster events in 2023 and multiple countries faced the most significant disasters in their modern histories. The global map shows event and peril patterns that contributed to the overall economic losses in 2023. The largest loss driver was earthquake, yet this was largely caused by a handful of events, notably the earthquake sequence in Turkey and Syria. Severe convective storms came second, with the largest individual losses concentrated in the United States and Europe. Graphic: Aon

Aon: Number of billion-dollar disasters in 2023 highest on record – Severe convective storms were the most damaging peril for insurers

LONDON, 23 January 2024 (Aon) – Aon plc, a leading global professional services firm, today published its 2024 Climate and Catastrophe Insight report, which identifies global natural disaster and climate trends to help make better decisions to manage volatility and enhance global resilience. The report reveals that the 398 global natural disaster events caused a $380 billion (2022: $355 billion) […]

NOAA reports 2023 hottest year on record, so far – “We will look back at 2023 and think of it as: remember that year that wasn’t so bad?”

By Lauren Sommer 28 December 2023 (NPR) – As 2023 draws to a close, it’s going out on top. “It’s looking virtually certain at this point that 2023 will be the hottest year on record,” says Zeke Hausfather, climate scientist at Berkeley Earth, a non-profit that analyzes climate trends. Though temperature records from December have […]

As global debt worries mount, is another crisis brewing? “You can take many, many countries today, and you will see that we are not far away from a public finances crisis”

By Yoruk Bahceli, Dhara Ranasinghe, and Maria Martinez 16 October 2023 LONDON (Reuters) – Record debts, high interest rates, the costs of climate change, health, and pension spending as populations age and fractious politics are stoking fears of a financial market crisis in big, developed economies. A surge in government borrowing costs has put high debt in […]

Two months of fire and flood: Greece’s climate disasters in 2023, visualized – “An unprecedented weather event, a catastrophe of immense proportions”

By Mithil Aggarwal and Jiachuan Wu 8 October 2023 (NBC News) – Greece is at war with climate change. Wildfires and record rainfall devastated the country this summer, first scorching entire forests then flooding complete towns. Here’s a look at two months of disasters that will leave the country changed for years. The fires The blaze […]

Brazil’s big cats under threat from wind farms – “Wind power is a fantastic proposal, and the northeast certainly has plenty of wind … but wind parks must also take into account what is happening here on the ground”

By Luciana Magalhaes and Samantha Pearson 17 September 2023 JUAZEIRO, Brazil – Weighing more than 100 pounds, big cats have long reigned over this hot and semi-arid region of Brazil, developing tougher paws for the scorched earth and reaching speeds of 50 miles an hour to bring down wild boar and deer. But nothing could […]

Swiss glacier watcher warns 2023 heat wave threatens severe melt again after record 2022 – “We can definitely say that we had very high melting in Switzerland and in Europe in general”

By Jamey Keaten 1 September 2023 GENEVA (AP) – A top glacier watcher has warned that a warm early summer combined with a heat wave last week may have caused severe glacier melt in Switzerland, threatening to make 2023 its second-worst year for ice loss after a record thaw last year. Matthias Huss of the GLAMOS […]

Heat dome shatters all-time U.S. records as Europe roasts – “Brutal” heat wave brings triple-digit temperatures from Chicago to New Orleans – 110 million people exposed to dangerous heat

By Andrew Freedman 24 August 2023 (Axios) – In a summer featuring countless heat domes and record-high temperatures and heat indices, the season appears to have saved the worst for last. The big picture: A sweltering, stagnant air mass is draped across the Central U.S., resulting in “dangerous,” “searing” and “brutal” heat. Meanwhile, southern Europe is also seeing another bout of […]

NASA announces July 2023 was hottest month on record – “The science is clear this isn’t normal”

By Sheri Walsh 14 August 2023 (UPI) – July 2023 was the hottest month on record in 143 years, as Americans felt “the effects of the climate crisis,” scientists at NASA’s Goddard Institute for Space Studies in New York announced Monday. According to NASA, July 2023 was on average 0.43 degrees Fahrenheit warmer than any […]

July 2023 sees multiple global temperature records broken – Global mean temperature temporarily exceeded the 1.5° C threshold – “The extreme weather which has affected many millions of people in July is unfortunately the harsh reality of climate change and a foretaste of the future”

8 August 2023 (C3S) – The month started with the daily global mean surface air temperature record being broken on four days in a row, from 3-6 July. All days throughout the rest of July were hotter than the previous record of 16.80°C, set on 13 August 2016, making the 29 days from 3-31 July […]

Extreme heat in North America, Europe, and China in July 2023 made much more likely by global warming – Without human-induced climate change these heat events would have been extremely rare: China heatwave would have been a 1 in 250-year event, and max heat like in July 2023 would have been virtually impossible in the U.S./Mexico region and Southern Europe

25 July 2023 (World Weather Attribution) – Following a record hot June, large areas of the US and Mexico, Southern Europe and China experienced extreme heat in July 2023, breaking many local high temperature records. July 2023 saw extreme heatwaves in several parts of the Northern Hemisphere, including the Southwest of the US and Mexico, […]
