CIA Investigating How To Manipulate Climate Change
2013-07-19 15:51:48

Brett Smith for redOrbit.com - Your Universe Online In a move that sounds vaguely reminiscent of one of Dr. Evil's plans, the CIA is planning to investigate how humans could potentially control the global climate. The 21-month project being run by the National Academy of Sciences and partially being funded by the CIA "is intended to provide a careful, clear scientific foundation that informs ethical, legal, and political discussions surrounding geoengineering," according to...

Ancient Algal Bloom Mystery Solved
2013-07-15 15:05:24

Brett Smith for redOrbit.com - Your Universe Online An ancient bloom of life that occurred just after the last ice age isn't what it seemed at first, according to new research in the journal Nature Geoscience. Scientists had long believed that the bloom, which occurred around 14,000 years ago, was spurred by rising sea levels washing iron into the ocean. However, the new study suggested that a "perfect storm" of conditions allowed for the bloom to happen, and not simply the abundance of...

Coral Reef Protection From Cloud Seeding
2013-07-11 04:51:24

April Flowers for redOrbit.com - Your Universe Online New research from the University of Leeds reveals threatened coral reefs could be protected from bleaching by warming oceans. The study proposes a targeted version of the geoengineering technique known as Marine Cloud Brightening (MCB) - seeding the clouds to cool sea surface temperatures - could give coral a fifty year "breathing space" to recover from acidification and warming. "Coral bleaching over the last few decades has been...

Clouds Affected By Pollutants Could Enhance Climate Cooling
2013-05-06 05:35:43

redOrbit Staff & Wire Reports - Your Universe Online While manmade pollution and other natural emissions are often blamed for their role in global warming, new research from the University of Manchester suggests that they could actually play a role in cooling the world´s climate. According to the study, which has been published in the journal Nature Geoscience, those emissions could make clouds brighter. Clouds, the researchers explain, are comprised of water droplets that...

Plants Are Natural Air Conditioners
2013-04-29 10:10:18

Brett Smith for redOrbit.com - Your Universe Online It has long been understood that plants are able to mitigate the forces of climate change by absorbing carbon dioxide from the air. However, a new study adds another dimension to the role played by plants in curbing global warming by showing that they also“¯emit gases that assist in cloud formation and atmospheric cooling. According to the study, which was recently published in the journal“¯Nature...

Microorganisms In Sea Spray Alter Ability Of Ocean To Seed Clouds
2013-04-23 11:09:06

April Flowers for redOrbit.com - Your Universe Online The ability of sea spray to form clouds over the ocean is influenced by ocean biology which alters the chemical composition of the spray. A team of scientists from the University of California, San Diego, is using a new approach to study tiny atmospheric particles called aerosols. These aerosols can influence climate by absorbing or reflecting sunlight and seeding clouds. "After many decades of attempting to understand how the ocean...

Volcanic Activity Would Have Helped Mars Sustain Liquid Water
2013-04-09 10:17:31

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that Earth´s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars — the planet would be able to sustain liquid water. According to the study, which appeared in the early online edition of Proceedings of the National Academy of Sciences (PNAS), greenhouse gases such as methane and carbon dioxide...

Scientists Analyze Costs And Benefits Of Rock Dissolving Practices
2013-01-22 12:14:08

Brett Smith for redOrbit.com - Your Universe Online Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ℠quick fix´ with potential long-term negative effects. However, despite the contentious nature of geoengineering, scientists from the Alfred Wegener Institute in Bremerhaven, Germany decided to analyze a ℠rock...

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...
