Climate experts say a fleet of wind-powered ships could be one of the more feasible solutions of climate engineering to reduce global warming.The Copenhagen Consensus on Climate has released an analysis paper that addresses a variety of proposed climate engineering options.The paper was written to address the question: "If the global community wants to spend up to, say $250 billion per year over the next 10 years to diminish the adverse effects of climate changes, and to do most good for the...

Geoengineering techniques aim to slow global warming through the use of human-made changes to the Earth's land, seas or atmosphere. But new research shows that the use of geoengineering to do environmental good may cause other environmental harm. In a symposium at the Ecological Society of America's Annual Meeting, ecologists discuss the viability of geoengineering, concluding that it is potentially dangerous at the global scale, where the risks outweigh the benefits."The bigger the scale of...

Geoengineering - deliberately manipulating physical, chemical, or biological aspects of the Earth system to confront climate change "“ could contribute to a comprehensive risk management strategy to slow climate change but could also create considerable new risks, according to a policy statement released by the American Meteorological Society (AMS) today.According to the Society, geoengineering will not substitute for either aggressive emissions reduction or efforts to adapt to climate...

Four expert speakers attended an event organized by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on 15 July, at the House of Commons, to address an audience curious about geo-engineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises. Introduced by Dr Brian Iddon MP, Dr Alan Gadian from the University of Leeds opened the seminar with a description of cloud albedo modification, explaining...

Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life, report the authors of a new study in the journal Geophysical Research Letters*. The culprit is atmospheric carbon dioxide, which even in a cooler globe will continue to be absorbed by seawater,...

Plants absorbed carbon dioxide more efficiently under the polluted skies of recent decades than they would have done in a cleaner atmosphere, according to new findings published this week in Nature.The results of the study have important implications for efforts to combat future climate change which are likely to take place alongside attempts to lower air pollution levels.The research team included scientists from the Centre for Ecology & Hydrology, the Met Office Hadley Centre, ETH...

President Barack Obama's science and technology director told the Associated Press on Wednesday that the controversial use of geoengineering needs to be considered an option for combating global climate change. "It's got to be looked at," said Holdren in his first interview since being confirmed. "We don't have the luxury of taking any approach off the table." Geoengineering involves manipulation of the environment on a large scale using methods such as fertilizing the Earth's oceans with...

Scientists in Germany and India said an experiment to determine whether depositing hundreds of tons of dissolved iron in the Southern Ocean can diminish global warming has produced disappointing results. In conducting the research, scientists "fertilized" a 115 square mile area of ocean by placing six tons of dissolved iron inside the core of an eddy -- a large, rotating column of water. The researchers hoped the iron would stimulate the growth of tiny planktonic algae known as phytoplankton,...

British scientists say they are looking for ways to reduce global temperatures and curb greenhouse emissions through geo-engineering. Researchers are looking into the feasibility of using artificial trees to absorb carbon dioxide or reflect sunlight away from Earth, the Times of London reported Sunday. The Royal Society, Britain's national academy of science, is preparing a report on the subject, the newspaper said. Our study aims to separate the science from the science fiction and offer...

According to a report in Friday's edition of the journal Science, skies all over the world are dimming due to increases in airborne pollution over the past 30 years.The new study compiles satellite and land-based data on global dimming over a longer period than had previously been available."Creation of this database is a big step forward for researching long-term changes in air pollution and correlating these with climate change," Kaicun Wang, of the University of Maryland, told the...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
