Study justifies closing airports in volcano event

The disruptive closing of some European airports after last year's volcanic eruption in Iceland was the right thing to do and may have saved lives, a new study concludes.

Small, mighty and mysterious: Researcher IDs atmospheric aerosols

(PhysOrg.com) -- There's a lot more to the atmosphere than air. With every breath, we inhale a nearly invisible mish mash of tiny particles known as aerosols. From droplets of water and trace gases like sulfuric acid to specks ...

Scientists better prepared to judge ash cloud

Scientists say they are now better prepared for measuring Iceland's volcanic ash problem, which is expected to continue for several months, after experiments using modelling and lasers to probe the atmosphere.

Scientists to measure impact of volcanic ash on ocean biology

A team led by scientists from the National Oceanography Centre in Southampton, have today set sail from Govan in Scotland towards the region of the North Atlantic Ocean affected by ash from the Icelandic volcano eruption ...

Atmospheric 'sunshade' could reduce solar power generation

The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according ...

Where does the Earth's heat come from?

Earth generates heat. The deeper you go, the higher the temperature. At 25km down, temperatures rise as high as 750°C; at the core, it is said to be 4,000°C. Humans have been making use of hot springs as far back as antiquity, ...

Volcanic ash particles under the microscope

Volcanic ash is hazardous to many aspects of our lives. When airborne, it can damage aircraft: its particles abrade aeroplane surfaces and can even cause failure to critical instruments. Once the ash falls, it can harm our ...
