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 Jeremy Hance, www.mongabay.com January 28, 2010 Sometime around 2050 researchers estimate that the global population will level-out at nine billion people, adding over two billion more people to the planet. Since, one billion of the world’s population (more than one in seven) are currently going hungry—the largest number in all of history—scientists are […]

ScienceDaily (Aug. 25, 2009) — The world’s last remaining “pristine” forest — the boreal forest across large stretches of Russia, Canada and other northern countries — is under increasing threat, a team of international researchers has found. The researchers from the University of Adelaide in Australia, Memorial University of Newfoundland in Canada and the National […]
By Noreen Parks In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, according to new research reported online June 20 in Geophysical Research Letters (2009, DOI 10.1029/2009GL038227). Of the atmospheric […]
In the Southern Indian Ocean, climate change is leading to stronger winds, which mix waters, bringing carbon dioxide up from the ocean depths to the surface. As a result, the Southern Ocean can no longer absorb as much atmospheric CO2 as before. Its role as a ‘carbon sink’ has been weakened, and it may now […]
by Asa Wahlquist VICTORIA’S bushfires have released a massive amount of carbon dioxide into the atmosphere – almost equal to Australia’s industrial emission for an entire year. Mark Adams, from the University of Sydney, said the emissions from bushfires were far beyond what could be contained through carbon capture and needed to be addressed in […]
From Climate Progress: Dr. Vicky Pope, head of climate change predictions at the Met Office’s Hadley Centre, writes in the UK Times that In a worst-case scenario, where no action is taken to check the rise in Greenhouse gas emissions, temperatures would most likely rise by more than 5°C by the end of the century.
