    The article “US Senate Considering Albedo Modification Geoengineering Proposal” appeared as I finished this article. It commented on the plan to introduce particles into the atmosphere to increase the reflective capability of the Earth’s atmosphere known as the albedo. Most responses correctly identified it as unwise. Isn’t it already happening?

    SUNNYVALE (KPIX 5) In a Silicon Valley research lab, scientists are working on what might be considered the option of last resort for global warming. Its an insurance policy, said researcher Sudhanshu Jain. Its called the Marine Cloud Brightening Project, and its designed to fight global warming by making clouds over the ocean thicker and brighter so they reflect more sunlight and cool the planet. The Sunnyvale team has reached a milestone with this high-pressure nozzle that uses salt water and looks like a normal water spray. But it took scientists a year to come up with the exact...

    San Jos (United States) (AFP) - US scientists and legal experts are calling for a strong, international authority to regulate any man-made interventions meant to combat global warming, amid fears that the technology could be harmful to the environment. The field known as geoengineering is not currently regulated by any institution or treaty, Edward Parson, professor of environmental law at the University of California, Los Angeles, explained Saturday. "If some nations decide this year to embark on a crude untested experimental attempt to do it, we cannot prevent it," Parsons said in San Jose, California at the American Society for...

    Schemes to tackle climate change could prove disastrous for billions of people, but might be required for the good of the planet, scientists say. That is the conclusion of a new set of studies into what's become known as geo-engineering. This is the so far unproven science of intervening in the climate to bring down temperatures. These projects work by, for example, shading the Earth from the Sun or soaking up carbon dioxide. Ideas include aircraft spraying out sulphur particles at high altitude to mimic the cooling effect of volcanoes or using artificial "trees" to absorb CO2. Despite the risk...

    Current schemes to minimize the havoc caused by global warming by purposefully manipulating Earth's climate are likely to either be relatively useless or actually make things worse, researchers say in a new study. The dramatic increase in carbon dioxide levels in the atmosphere since the Industrial Revolution is expected to cause rising global sea levels, more-extreme weather and other disruptions to regional and local climates. Carbon dioxide is a greenhouse gas that traps heat, so as levels of the gas rise, the planet overall warms. In addition to efforts to reduce carbon dioxide emissions, some have suggested artificially manipulating the...

    Geoengineering hopes revived as study of iron-fertilized algal blooms shows they deposit carbon in the deep ocean when they die. In the search for methods to limit global warming, it seems that stimulating the growth of algae in the oceans might be an efficient way of removing excess carbon dioxide from the atmosphere after all. Despite other studies suggesting that this approach was ineffective, a recent analysis of an ocean-fertilization experiment eight years ago in the Southern Ocean indicates that encouraging algal blooms to grow can soak up carbon that is then deposited in the deep ocean as the algae...

    German researchers have re-ignited debate over geo-engineering by saying that seeding oceans with iron is an effective way to lock up CO2. While the principle behind seeding is simple enough the iron acts as a fertilizer for phytoplankton, which multiply and consume carbon dioxide as they grow the topic is fiercely debated. The core of the argument is also simple: its probably impossible to predict what other environmental impacts phytoplankton fertilization would have.

    Blue skies would fade to hazy white if geoengineers inject light-scattering aerosols into the upper atmosphere to offset global warming. Critics have already warned that this might happen, but now the effect has been quantified. Releasing sulphate aerosols high in the atmosphere should in theory reduce global temperatures by reflecting a small percentage of the incoming sunlight away from the Earth. However, the extra particles would also scatter more of the remaining light into the atmosphere. This would reduce by 20 per cent the amount of sunlight that takes a direct route to the ground, and it would increase levels...
