Natural Disaster Increase Partly Due to Improved Reporting

“In our work on natural disasters, we visualize data from EM-DAT, the most comprehensive international disaster database. Make a chart of the number of recorded disaster events over time — like the one above — and it looks like the number of disasters rose alarmingly from the 1970s to the millennium. This has led to many media outlets and organizations claiming that the number of disasters has quadrupled over the last 50 years.

However, as EM-DAT itself makes clear, most of this is due to improvements in recording. The Centre for Research on the Epidemiology of Disasters, which builds this database, was not established until 1973, and didn’t start publishing EM-DAT until 1988.

The number of recorded disasters increased due to more focused efforts to obtain globally comprehensive data and improvements in communication technologies, which allowed more events to be included, even in the planet’s most remote areas.”

Despite Some of Europe’s Worst Wildfires in Decades, Deaths Remain Low

“Wildfires in Britain and Europe this year are among the worst in decades, yet direct deaths are at some of the lowest levels, according to a Telegraph analysis.

As of early August, 505,683 hectares of land have burned across Europe, forcing the evacuation of more than 360,000 people as uncontrollable flames reach major cities, towns, and villages.

The problem is global – in the US, Nevada declared a state of emergency over the weekend after a wildfire caused more than 42,000 people to evacuate their homes.

But what sets 2026 apart isn’t just the vast areas of land burned, but how few deaths have been caused by the fires.

This summer, just 14 people are reported to have died in European wildfires, the vast majority in a single blaze in Almería, southern Spain…

The decline reflects a decade of investment and problem-solving, say experts.

Early-warning systems, evacuation planning, and firefighting capacity have all been built up in Europe and around the world in response to the growing risk. In short, we are leading and adapting.”

AI Extends Lead Time for Global Tropical Cyclone Forecasts

“Tropical cyclones are among the most dangerous and costly weather phenomena, yet forecasting them remains a profound scientific challenge. Here, we introduce WeatherNext Cyclones (WN-C), an AI operational weather model producing state-of-the-art ensemble forecasts for track, intensity, and size of tropical cyclones worldwide. Trained on a combination of global analysis data1 and a global database of historical tropical cyclones2,3, WN-C generates large ensembles of possible global weather and cyclone scenarios extending 15 days into the future. Evaluated on tropical cyclones from 2023–2025, the track, intensity and wind radii predictions from WN-C offer an average of a day or more of lead time advantage over leading operational models, an improvement in accuracy comparable to the progress seen over the last decade of operational development.”

Earthquake Upgrades Helped Limit Damage in Japan’s Kyushu

“When a 6.8-magnitude earthquake jolted southwestern Japan last week, its force mirrored the kind of seismic shocks capable of flattening cities and claiming hundreds or even thousands of lives.

Yet across the island of Kyushu, the violent shaking destroyed or heavily damaged just a few hundred buildings. One week after the quake, the death toll was 38…

'We see that there are huge differences in the number of casualties,' said Katsuichiro Goda, a professor of earthquake engineering at Western University in Canada. Mr. Goda, who conducted field reconnaissance in Kumamoto after the 2016 quakes, credits much of that difference to how the prefecture has rebuilt over the past decade, including spending tens of billions of dollars on earthquake proofing.”

Greece Turns to Space in Fight Against Wildfires

“With wildfires burning north-west of Athens, Greece is testing whether a new fleet of thermal satellites can give firefighters earlier warning and a clearer view of the blazes that are becoming harder to contain in a warming climate.

The Hellenic Fire System, a constellation of four compact, low-flying thermal satellites, transmitted its first images to Earth in June. The system is due to become fully functional in September, with firefighters still being trained to use it.

But it is already providing data to authorities, including about devastating fires that ripped across popular Greek island resorts and the region of Attica near Athens in recent weeks.”
