As poor countries are likely to be the ones most negatively affected by possible efforts to geoengineer as a means of mitigating the worst effects of anthropogenic climate change, they should have a say in global discussions on the matter, according to a new report from London-based Overseas Development Institute (ODI).
Researchers have come up with a sophisticated new computer modeling algorithm they say makes it possible to predict the effect of injecting sulfur dioxide at high altitudes would have on global temperatures. Is that a good thing?
Cloud seeding efforts are now being discreetly (or otherwise) undertaken in more than 50 countries around the world — with the aim often being to force precipitation to fall in areas that are in drought or experiencing water shortages. Or, alternately, to force rain to fall on your country’s farmland rather than on the neighboring country’s farmland.
Will the Trump Administration “open the door” to planet-scale geoengineering experiments? That’s the question posed in an article that I recently came across, one which referenced plans by Harvard engineers David Keith and Frank Keutsch to test in 2018 (in Arizona) the high-altitude spraying of sulphate particles as a means of limiting warming.
A new European-wide analysis has concluded that climate engineering, also known as geoengineering, is not a viable European near-term climate policy. The report, European Transdisciplinary Assessment of Climate Engineering (EuTRACE), was funded by the European Union, and brought together researchers and scientists from 14 European partners institutions, covering a wide range of … [continued]
If you haven’t heard about the MIT Climate CoLab, you’re about to. It’s a rapidly growing public community of over 30,000 members from across the world. Participants can enter the CoLab’s recently announced batch of 22 contests seeking high-impact ideas on how to tackle climate change. The contests cover a broad … [continued]
A National Research Council committee concluded that there is no substitute for “dramatic reductions” in greenhouse gas emissions to mitigate the negative consequences of man-made climate change. Their findings were published in a two-volume evaluation of proposed climate intervention techniques — also known as geoengineering — a study that was … [continued]
In a world where the renewable energy solution to climate change is a problem bogged down in politics and economics, geoengineering can sometimes look like the perfect solution. As the University of Leeds puts it, “deliberate, large-scale intervention in the Earth’s climate system” sounds wonderful — especially if it bypasses … [continued]
Former U.S. vice-president Al Gore pulled no punches about geoengineering in a phone conference with reporters on Wednesday. He was apparently reacting to a suggestion in a leaked draft summary of the forthcoming climate solutions section of the UN Intergovernmental Panel on Climate Change fifth climate assessment report. The definitive … [continued]
OK, first of all, this CO2-absorbing street lamp looks super cool! Secondly, it absorbs CO2! Thirdly, 150-200 times more than a tree! OK, I’m calming down, and I realize it has a ways to go to get to actual widespread use in the real, physical, CO2-filled world. http://youtu.be/wuWDex5mh5Y French … [continued]
