Why some scientists are worried about a surprisingly cold ‘blob’ in the North Atlantic Ocean
It is, for our home planet, an extremely warm year. Indeed, last week we learned from the National Oceanic and Atmospheric Administration that the first eight months of 2015 were the hottest such stre...
Can Rain Clean The Atmosphere?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is co...
Scientists call for international authority on climate geoengineering
Efforts to reverse man-made climate change need international oversight before research can proceed, a meeting of scientists has heard.
Arctic sea ice ecology and history
The Arctic sea ice covers less area in the summer than in the winter. The multi-year (i.e. perennial) sea ice covers nearly all of the central deep basins. The Arctic sea ice and its related biota ar...
Clathrate gun hypothesis
The clathrate gun hypothesis is the popular name given to the hypothesis that increases in sea temperatures (and/or falls in sea level) can trigger the sudden release of methane from methane clathrate...

Shutdown of thermohaline circulation
A shutdown or slowdown of the thermohaline circulation is a postulated effect of global warming. Global warming could, via a shutdown or slowdown of the thermohaline circulation, trigger localised coo...

Ocean anoxic event
Oceanic anoxic events or anoxic events (Anoxia conditions) occur when the Earth's oceans become completely depleted of oxygen (O2) below the surface levels. Euxinic (Euxinia) refers to anoxic conditio...
