Strong heat loss and brine release during sea ice formation in coastal polynyas act to cool and salinify waters on the Antarctic continental shelf. Polynya activity thus both limits the ocean heat flux to the Antarctic Ice Sheet and promotes formation of Dense Shelf Water (DSW), the precursor to Antarctic Bottom Water. However, despite the presence of strong polynyas, DSW is not formed on the Sabrina Coast in East Antarctica and in the Amundsen Sea in West Antarctica.

The populations of the Adelie and Chinstrap penguin species are declining as there shortage of food and their snowy habitat is shrinking

Commonwealth rich nations are contributing less towards the global effort to tackle climate change, while poorer nations are over-achieving on pledges, a British charity said on Monday.

Although we all show concern or pay lip service on increasing phenomena of climate change, there is lack of discussions or community mobilisation as to how to conserve environment and curb the phen

The island of Saint Louis in Senegal was listed in 2000 as a UNESCO World Heritage site, but it has since fallen into disrepair.

Upgrading Asia-Pacific's biggest ports to cope with the effects of climate change will cost up to $49 billion, but the bill could be even higher if no action is taken, researchers said.

The number of people fleeing crop failures, droughts and rising sea levels will grow drastically over the next three decades if world governments do not intervene, according to a World Bank report

The world’s greatest forests could lose more than half of their plant species by the end of the century unless nations ramp up efforts to tackle climate change, according to a new report on the imp

NEW YORK (Thomson Reuters Foundation) - An environmental advocacy group sued the U.S.

In ancient hothouses lacking ice sheets, the origins of large, million-year (myr)-scale sea-level oscillations remain a mystery, challenging current models of sea-level change. To address this mystery, we develop a sedimentary noise model for sea-level changes that simultaneously estimates geologic time and sea level from astronomically forced marginal marine stratigraphy. The noise model involves two complementary approaches: dynamic noise after orbital tuning (DYNOT) and lag-1 autocorrelation coefficient (ρ1).
