Mineral dust sprinkled in oceans could absorb vast amounts of carbon: study

  • PDF

altSprinkling billions of tonnes of mineral dust across the oceans could quickly remove a vast quantities of climate-warming carbon dioxide from the atmosphere, according to a new study.

The proposed "geoengineering" technique would also offset the acidification of the oceans and could be targeted at endangered coral reefs, but it would require a mining effort on the same scale as the world's coal industry and would alter the biology of the oceans.

"It certainly is not a simple solution against the global warming problem," said Peter Köhler, at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany, who led the study. It would require 100 large ships operating all year to distribute 1bn tonnes of the mineral olivine, although it might be possible to use the ballast water in existing shipping instead.

Boris Johnson says snow casts doubt on climate change science

  • PDF

altThe one thing we can now forecast with near certainty during any cold snap is that a Telegraph writer will use the plunging mercury to breezily state it provides the necessary proof to declare that the theory of global warming is over-hyped, unscientific bunkum.

The typical reaction to such verbiage is mocking laughter, or, if you've awoken on the wrong side of the bed, huffy exasperation. The best strategy is to view these articles as trolling, for that is largely what they are: blatant attempts to jam a sharp stick into a seething nest that is The Climate Debate. These writers want to wind you up and provoke a reaction. By doing so, you are playing into their hands. Do not feed the trolls, as the saying goes.

Climate change inaction the fault of environmental groups, report says

  • PDF

altA Harvard academic has put the blame squarely for America's failure to act on climate change on environmental groups. She also argues that there is little prospect Barack Obama will put climate change on the top of his agenda in his second term.

In a research paper, due to be presented at a Harvard forum next month, scholar Theda Skocpol in effect accuses the DC-based environmental groups of political malpractice, saying they were blind to extreme Republican opposition to their efforts.

'Dark snow' project turns to crowdfunding for Greenland expedition

  • PDF

altThere is already much excitement in the arts, media and beyond about the potential of crowdfunding - via sites such as Kickstarter and IndieGoGo – to finance projects that might others have remained an unfulfilled dream. To date, though, few scientific expeditions have successfully utilised crowd-funding.

The Dark Snow Project hopes to change this. Jason Box, a climatologist based at the Byrd Polar Research Center at Ohio State University, is hoping to raise $150,000 over the coming months to pay for an expedition this summer up onto the "ice dome" of Greenland to gather samples of snow. The project's website explains:
