Double edged sword as Southern Ocean “regains” its capacity to absorb atmospheric CO2

The Guardian reports, 11th September 2015: The Southern Ocean has started to absorb more greenhouse gases after a period when the vast ocean’s uptake had slumped by about a half, a study has found. The ocean’s role as a crucial carbon “sink” appeared to be waning throughout the 1990s, but after 2002 it began to […]

Eco-based engineering could protect coastal cities from rising sea levels

The Guardian reports, 6th August 2015: ‘Eco-based’ engineering systems to put sediment-laden water back on to the delta plains could prevent the loss of 500,000 hectares of wetlands in Mississippi and greatly reduce annual flood damage costs to New Orleans and the Louisiana coast. Rich nations spend huge sums to keep the seas at bay […]

Scientists surprised by Arctic sea ice recovery in 2013

The Guardian reports, 20th July 2015: Ice in the Arctic staged a surprise revival in 2013, bucking the long-term trend of decline, according to the first analysis of the entire ice cap’s volume. The revival was the result of cooler temperatures that year and suggests that, if global warming was curbed, the Arctic might recover […]

Tropical weather systems are accelerating Arctic ice melting

The Washington Post, 13th July, reports: Relatively few tropical storms ever make it as far north as Greenland, the ice-covered island that straddles the Arctic Circle east of Canada. But the ones that do appear to be inflicting serious damage — and not just to Greenland. A recently published study shows that warm, tropical air […]
