‘Roaming reactions’ study to shed new light on atmospheric molecules

(University of New South Wales) For the first time, a team of chemists has lifted the hood on the mechanics involved in the mysterious interplay between sunlight and molecules in the atmosphere known as ‘roaming reactions’, which could make atmospheric modelling more accurate.

Can other gases help explain Mars methane mystery?

The European Space Agency’s Trace Gas Orbiter has unexpectedly detected carbon dioxide and ozone in Mars’ atmosphere where the elusive methane should be, researchers in the UK and Russia have announced. The two gases may be hindering the probe’s methane detections.

A new chemical analysis upends conventional explanation for global cooling

(University of Houston) Scientists have long known the earth cooled dramatically about 13,000 years ago, and the most likely explanation has been that it was caused by a massive object slamming into earth from space or bursting in the atmosphere. But now researchers have reported new evidence for another, more likely explanation – the eruption of a volcano on what is now the European continent, upending thinking about an event that shaped future evolution.

Geoengineering is just a partial solution to fight climate change

(Rutgers University) Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory, according to a Rutgers co-authored study in the journal Earth System Dynamics. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.

Removing toxic chemicals from water: New environmentally-friendly method

Researchers have developed a new environmentally friendly method for removing toxic chemicals from water. A newly invented machine, called the Matrix Assembly Cluster Source (MACS), has been used to design a breakthrough water treatment method using a solvent-free approach.
