Hidden magma fields extended historical warm periods
Gigantic magma fields under ancient volcanoes may have continued to emit carbon dioxide long after surface eruptions ceased, a new study shows, according to AFP.
It may explain why earlier periods of climate change in Earth's history lasted for unexpectedly long periods.
Among other things, scientists have been amazed that it took nearly five million years for the atmosphere to recover from the mass extinction 252 million years ago, the largest in Earth's history. Scientists believe the event, which ended the Perma Period, was caused by massive volcanic eruptions in Siberia.
- We believe we have found an important piece of the puzzle to how the Earth's climate was disturbed, and perhaps just as importantly, how it recovered, says researcher Benjamin Black.

Extreme drought hit nearly half the Earth's surface by 2023
There has been a tripling of land area affected by drought since the 1980s, according to a report published in the Lancet Countdown. Climate change is singled out as the cause.
Last year, 48 percent of the land area experienced at least one month of extreme drought, compared to 15 percent in the 1980s. At the same time, the occurrence of heavy rain has increased, creating a risk of flooding.
If greenhouse gas emissions are not reduced, droughts and extreme weather events will become more frequent and more intense, according to the report.

Still no snow on Fuji – for the first time in 130 years
The first snow of the season has yet to fall on Japan's highest Mount Fuji, reports Japan Today. It is the first time since the measurements started 130 years ago that the mountain is snow-free this late in the year.
Normally, the first snowfall occurs sometime in October.
The summer in Japan was the hottest on record and temperatures have continued to be unusually high.
A single event cannot be immediately linked to climate change, but the lack of snow on Fuji is in line with how climate scientists assess that a warmer world is manifesting itself, writes the BBC.
