By Staff WritersWashington (AFP) March 15, 2010 — Adding iron to the world’s oceans to capture carbon and fight global warming could do more harm than good, as the mineral appears to boost the growth of a plankton that produces a deadly neurotoxin, a study published Monday shows. Researchers led by Charles Trick of […]
By TOM ARUPMarch 15, 2010 THE nation’s two leading scientific agencies will release a report today showing Australia has warmed up significantly over the past 50 years. It is a response to recent attacks on the science underpinning climate change. The State of the Climate snapshot, drawn together by the CSIRO and the Bureau of […]
(A) Surface distributions of Ω aragonite, S, fraction of sea ice meltwater (f SIM), and TA in surface water observed between depths of 0 and 20 m. f SIM was estimated by using 18O and S measurements (12, 13). Gray contour lines indicate isobaths of 1000, 2000, and 3000 m. (B) Relationship between Ω aragonite […]
CO2 is the single most important human-emitted greenhouse gas in the atmosphere, contributing 63.5 %(2) to the overall global radiative forcing. However, it is responsible for 85% of the increase in radiative forcing over the past decade and 86% over the last five years. For about 10,000 years before the industrial revolution, the atmospheric abundance […]
Last Updated: Monday, March 8, 2010 | 3:03 PM ET CBC News Developed countries are “outsourcing” more than a third of their carbon emissions associated with products and services to other countries, researchers say. A study of trade data found that some countries in Western Europe have more than half of their total carbon dioxide […]
As the Bluff oyster industry watches for hopeful signs of recovery, oyster fishers in the US are witnessing cause for concern, Craig Welch, of The Seattle Times, reports. The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, the shellfish growers of Willapa […]
By Victoria GillScience reporter, BBC News, Portland A century of whaling may have released more than 100 million tonnes – or a large forest’s worth – of carbon into the atmosphere, scientists say. Whales store carbon within their huge bodies and when they are killed, much of this carbon can be released. US scientists revealed […]
By Robin McKie, science editorThe Observer, Sunday 21 February 2010 Huge vents covering the sea-floor – among the strangest and most spectacular sights in nature – pour carbon dioxide and other gases into the deep waters of the oceans. Last week, as researchers reported that they had now discovered more than 50,000 underwater volcanic springs, […]
Report for the UN into the activities of the world’s 3,000 biggest companies estimates one-third of profits would be lost if firms were forced to pay for use, loss and damage of environment [UPDATE: Fixed broken link to Stern review – thanks to the good folks at LearnStuff.] By Juliette Jowitwww.guardian.co.uk, Thursday 18 February […]
Press release issued 14 February 2010 A new model, capable of assessing the rate at which the oceans are acidifying, suggests that changes in the carbonate chemistry of the deep ocean may exceed anything seen in the past 65 million years. The model also predicts much higher rates of environmental change at the ocean’s surface […]
