Scientists from the US Geological Survey (USGS) have identified the oldest large body of seawater, more than a kilometre under Chesapeake Bay in the USA
The world’s oceans could see a 170 per cent increase in acidification by the end of the century, according to a research summary led by the International Geosphere-Biosphere Programme (IGBP)
A new study published in Nature Geoscience suggests that the seafloor off the coast of northern Siberia is releasing more than twice as much methane as previously estimated

'Missing heat' found

Suggestions that global warming has slowed or even stopped are in doubt following the publication of a new study that has identified the ‘missing heat’ in the global climate system
Strong growth in coal consumption has consolidated the fuel as the main source of carbon dioxide emissions, according to the Global Carbon Project’s (GCP) annual analysis of global carbon emissions
Neither solar activity nor the Sun’s blocking of cosmic rays is responsible for significant global warming, says a study in Environmental Research Letters
Hunting by Aboriginals in Australia’s Western Desert can actually increase the populations of the hunted animals, according to a recent study published in Proceedings of the Royal Society B
The fact that more tropical rain falls on the Northern Hemisphere than in the south has been linked to ocean currents, overturning the previous theory that it was caused by the shape of the ocean basins
Coastal erosion in Eastern Siberia is accelerating rapidly as increasing Arctic temperatures reduce sea-ice extent, allowing waves to wash away the permafrost

Rising sea levels, more intense drought and severe storms caused by climate change will put about 12 million people in 23 East Asian cities at risk and jeopardise US$864billion in assets
Average summer temperatures experienced by the eastern Canadian Arctic during the past century are higher than they have been at any time over the past 44,000 years, and perhaps as long ago as 120,000 years
Scientists have used a new method for determining biodiversity to reveal a series of new biodiversity hotspots for fish
The decline of shark populations through overfishing can have a detrimental effect on coral reefs, according to a new study published in PLoS One
A new study has found that the Arctic Ocean is acidifying more rapidly and more widely than projected

Ocean mixing explained

A team of researchers has solved the mystery of how deep and mid-depth ocean waters are mixed, providing a vital insight for climate modellers
Parts of Europe have seen the temperatures of their hottest days and coldest nights increase by more than four times the global average change since 1950, according to a new study
