Deep learning can predict tsunami impacts in less than a second

Detailed predictions about how an approaching tsunami will impact the northeastern coastline in Japan can be made in fractions of a second rather than half an hour or so—buying precious time for people to take appropriate ...

Irregular heartbeat of the Sun driven by double dynamo

A new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface ...

New calculations to improve CO2 monitoring from space

How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth's greenhouse ...

How the ice ages ended

A study of sediment cores collected from the deep ocean supports a new explanation for how glacier melting at the end of the ice ages led to the release of carbon dioxide from the ocean.

Stratospheric aerosols and their impact on Sahelian rainfall

(Phys.org) —The Sahelian drought of the 1970s-1990s was one of the largest humanitarian disasters of the last fifty years, causing up to 250,000 deaths and creating 10 million refugees. This drought has been attributed ...

Study provides new insights on drought predictions in East Africa

(Phys.org)—With more than 40 million people living under exceptional drought conditions in East Africa, the ability to make accurate predictions of drought has never been more important. In the aftermath of widespread famine ...
