Could we store carbon dioxide as liquid lakes under the sea?

From New Scientist Sumatra: the Sunda trench lies close by far beneath the ocean Planet Observer/Getty By Michael Marshall Here is a radical solution to dangerous climate change: create lakes of liquid carbon dioxide on the seabed, and keep the greenhouse gas out of the air. As well as cutting our emissions of carbon dioxide,…

Another geoengineering idea – gaming coalition modeled

From the Carnegie Institution  comes a nutty consensus type idea, modeled in game-theory, implemented by an equally nutty future coalition. Law of unintended consequences anyone? Geoengineering by coalition Washington, D.C.—Solar geoengineering is a proposed approach to reduce the effects of climate change due to greenhouse gasses by deflecting some of the sun’s incoming radiation. This…

Sunshade geoengineering people apparently have been in the midday sun too long

From the Carnegie Institution , not just aerosol injections, but effective aersol injections. Law of unintended consequences be damned. Improving effectiveness of solar geoengineering Washington, D.C.— Solar radiation management is a type of geoengineering that would manipulate the climate in order to reduce the impact of global warming caused by greenhouse gasses. Ideas include increasing…

Sea cucumbers: Dissolving coral reefs?

From the Carnegie Institution  and Stanford University comes word of this paper in JGR. Washington, D.C. — Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research led by Carnegie’s Kenneth Schneider analyzed the role…

Shocker – Ken Caldeira resigns as IPCC AR5 lead author

(via Tom Nelson) Ken Caldeira resigns as IPCC lead author, saying: “…it is not clear how much additional benefit there is to having a huge bureaucratic scientific review effort under UN auspices…” New Directions for the Intergovernmental Climate Panel – NYTimes.com Clearly, at the outset, the early IPCC reports played an important role showing that…

Water evaporated from trees cools global climate

From the Carnegie Institution – maybe we should build more cooling towers. Washington, DC. — Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research from Carnegie’s Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation,…

CO2 causes unchecked wetdry

This is important because scientists are concerned that unchecked global warming could cause already dry areas to get drier. (Global warming may also cause wet areas to get wetter.) Cao and Caldeira’s findings indicate that reducing atmospheric carbon dioxide could prevent droughts caused by climate change. Via press release in Eurekalert, from Stanford, and the…
