MIT study shows climate change mitigation potential of geoengineering oceans

Environmental News Network: Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols, which can directly reflect sunlight or increase cloud cover and reflectivity, resulting in a cooling effect. The ability of phytoplankton...

Irish Times: Sir, As the world watches, debates and, hopefully, responds to the refugee crisis unfolding in the Mediterranean, it may be worthwhile reflecting that this current wave of migration is simply a taste of things likely to come within the next few decades. Over 50 per cent of humanity now lives within a few kilometres of the sea, and most of the worlds major cities are on the coast and already liable to flooding. It is now overwhelmingly accepted that, as global climate change continues, many coastal...

What is needed is a willingness by politicians and big business to utilize them, Klein said. What she called "a transformative agenda." "The scientists are telling us clearly that we must change and that we are running out of time. The engineers are telling us we can do it, that the technology...

Climate Change Morphs Ecosystems In Blink Of Geologic Time

St. Louis Post-Dispatch: As atmospheric CO2 (carbon dioxide) levels continue to rise, enormous tree-planting campaigns are often touted among ways humans can try and limit climate change. In Africa, where some regions have been seen as ideal for this type of project, Guy Midgley has a message: Hang on. The botany and zoology professor at Stellenbosch University in South Africa explained that trees are already moving into African grasslands. Higher levels of carbon dioxide are beginning to change those ecosystems into...

AAP: Opposition Leader Bill Shorten says Peter Dutton's apology for joking about the impact of climate change on Pacific island nations is not about what he said, but the fact that he was caught. The immigration minister was picked up by an overhead microphone making a quip about "water lapping at your door" at a media opportunity with Prime Minister Tony Abbott in Canberra on Friday. The comment has been heavily criticised by Pacific island leaders. "I made a mistake, I apologise to anyone who has...
