A Taste of Medicine - St Georges University of London BBC/OU Open2.net - Home Copyrighted image Credit: The Open University Open2.net fades away... For ten years, give or take, Open2.net was the online home of Open University and BBC programming. Over the last few months, though, we've been moving into OpenLearn, creating one home for all The Open University's free learning content. It means we share a home with the Open University's iTunesU and YouTube channels, and much more besides. You can use the navigation at the top of this page to explore what we have on offer. There's lots to do - you could watch Evan Davis exploring the state of British manufacturing7; explore the frozen planet8; get to know the science and history of the Olympics9 or have a look at our free courses. Most of the content from Open2.net has been brought across; if you've landed here after typing or searching for an Open2.net URL then you're probably looking for something that fitted into one of these categories: Open2 forums We still want you to join in, comment and share your views.

The Royal Society report: some more follow-up « Heliophage The Royal Society report: some more follow-up Some more discussion and fall out from Tuesday’s report. Peter Cox (a member of the Royal Society working group) and Hazel Jeffery have a feature in Physics World that effectively recaps the report, but puts a more pro-geoengineering spin on it. Given that conventional mitigation now appears insufficient to avoid dangerous climate change, do we have a plan B? This also includes a rather more easily understood, and I think generally better, summary diagram than the one included in the report (“Figure 5.1″, as gently mocked by my friend Geoff), which leaves out some of the modalities that Cox and Jeffery don’t think so much of, and which puts everything in the context of conventional mitigation. The Cox and Jeffery plot And here’s 5.1. Geoengineering the climate, figure 5.1 One interesting thing is that Cox and Jeffery don’t give any diagram space to enhanced weathering: I wonder why not?

Home MIT World Disagreeing with the Copenhagen geoengineering consensus « Heliophage Disagreeing with the Copenhagen geoengineering consensus At roughly the same time as the Royal Society was weighing in on geoengineering last week, so was Bjorn Lomborg’s Copenhagen Consensus project, considerably less convincingly. The context here was a process by which a panel of five economists was briefed on a range of investments that might be made to do something about climate change: for each intervention there was a briefing paper and a pair of discussion papers analysing that briefing. After reading all this and hearing oral arguments the panel voted on which of the interventions was considered the best investment. The intervention portfolio on offer featured carbon taxes of various strengths, R&D into new energy technologies, carbon sequestration and direct-air carbon capture, planning for adaptation, measures to control methane and black carbon, geoengineering of various types, forest management and expansion and north-south technology transfer.

Fixing the Sky James Rodger Fleming Paper, 344 pages, 43 illus. ISBN: 978-0-231-14413-1 $24.95 / £17.00 September, 2010 Cloth, 344 pages, 43 illus. ISBN: 978-0-231-14412-4 $27.95 / £19.95 As alarm over global warming spreads, a radical idea is gaining momentum. These ideas might sound like science fiction, but in fact they are part of a very old story. Showing what can happen when fixing the sky becomes a dangerous experiment in pseudoscience, James Rodger Fleming traces the tragicomic history of the rainmakers, rain fakers, weather warriors, and climate engineers who have been both full of ideas and full of themselves.

GISS: Science Briefs: Pinatubo Climate Investigation Pinatubo Climate Investigation January 1997 Volcanic eruptions, if large enough, can blast gas and dust into the Earth's lower stratosphere. Volcanic haze scatters some of the incoming sunlight back to space, thus reducing solar heating of the Earth's surface. The idea that volcanos effect climate is not new. The "Pinatubo" research team at GISS, a group of scientists, students and educators, is studying the effect of volcanos and other forcings on climate. With a single volcano it may be hard to identify a climate "signal" among the large amount of weather and climate "noise", that is, the unforced chaotic fluctuations of the atmosphere and ocean. A detailed test of climate models will be possible for the Pinatubo eruption, because of global satellite measurements of the volcanic aerosols and the climate change.

'Climate fix' ship sets sail with plan to dump iron - environment - 09 January 2009 UPDATED: The German science ministry has suspended Victor Smetacek's ocean seeding experiment, demanding that an independent assessment into the environmental impacts of the experiments be carried out before the iron filings are dumped in the Southern Ocean. The Alfred Wegner Institute confirmed to New Scientist that operations on board were suspended until further notice. The largest and to date the most comprehensive experiment to soak up greenhouse-gas emissions by artificially fertilising the oceans set sail from South Africa earlier this week. The ambitious geoengineering expedition has caused a stir among some campaigning groups, but has the scientific backing of the UK, German, and Indian governments, as well as the International Maritime Organisation. Within weeks, the ship's crew hope to dump 20 tonnes of ferrous sulphate into the Southern Ocean. 'Anti-offset crusaders' Planktos eventually cancelled the expedition and the company folded due to lack of funds. 'Slippery slope'

Board Statement - STATEMENT BY THE BOARD OF DIRECTORS OF THE CLIMATE RESPONSE FUND March 19, 2010 We, the members of the board, are honored that more than 195 scientific and policy leaders from around the world will join us at the Asilomar Conference on Climate Intervention Technologies, March 22-26, 2010. CRF’s objective for this conference is solely to initiate relevant discussions between scientists, environmentalists and policy makers and to facilitate the development of voluntary guidelines for the field of climate intervention technologies or geoengineering. The mission of the Climate Response Fund: When the Climate Response Fund was formed we discussed and considered all potential activities related to climate intervention that CRF might fund, including among other activities field experiments in tropospheric aerosols, adding alkalinity to the ocean and ocean fertilization. Our mission is to: Foster safe and responsible research on climate intervention by: The Climate Response Fund has been publicly criticized by certain parties because Mr. Amb. Dr. Dr.
