Improved interpretation of volcanic traces in ice

How severely have volcanoes contaminated the atmosphere with sulfur particles in past millennia? To answer this question, scientists use ice cores, among others, as climate archives. But the results differ, particularly in ...

Volcanoes cause climate gas concentrations to vary

Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the processes in the ...

Archaeons shown to thrive on fireworks ingredient

(Phys.org) —A new study in the Netherlands has found a deep-sea microbe living in high-temperature hydro-thermal vents can thrive on chlorate and perchlorate anions. Perchlorate, an ingredient in rocket fuel and fireworks, ...

US to require lower-sulfur gasoline

The Obama administration is expected to propose new rules Friday that would slash the amount of sulfur in gasoline, one of the most significant steps the administration can take this term toward cutting air pollution, said ...

Wood on the seafloor: An oasis for deep-sea life

Trees do not grow in the deep sea, nevertheless sunken pieces of wood can develop into oases for deep-sea life - at least temporarily until the wood is fully degraded. A team of Max Planck researchers from Germany now showed ...

Nanofibers clean sulfur from fuel

(Phys.org)—Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively ...

Benefits, risks of using geoengineering to counter climate change

If they wanted to, nations around the world could release globe-cooling aerosols into the atmosphere or undertake other approaches to battle climate change, an authority on environmental law said Monday. He recommended international ...
