Simon Fraser University Tinkering with climate change through climate engineering isn't going to help us get around what we have to do says a new report authored by researchers at six universities, including Simon Fraser University. After evaluating a range of possible climate-altering approaches to dissipating greenhouse gases and reducing warming, the interdisciplinary team concluded there's no way around it. We have to reduce the amount of carbon being released into the atmosphere....

Ending Geoengineering Prematurely May Worsen Global Warming
2014-02-19 11:37:28

Ranjini Raghunath for redOrbit.com - Your Universe Online Starting and then stopping geoengineering techniques could aggravate global warming, scientists warn. A proposed mitigation technique which involves spewing sulfur particles into the atmosphere could help combat climate change – but if stopped after being implemented, it could worsen the problem, according to a new study from University of Washington researchers. Spewing sulfur particles into the air could cool the planet by...

As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions. The new study, published today, 18 February, in IOP Publishing's journal Environmental Research Letters, has highlighted the risks of...

Geoengineering Earth's Climate
2013-12-18 10:37:49

Ranjini Raghunath for redOrbit.com - Your Universe Online Artificial clouds that reflect sunlight back into space. A StratoShield that spews sulfur dioxide particles into space like a volcano, cooling the planet’s surface. Microbial blooms that grow on iron injected into the ocean and trap carbon dioxide from the atmosphere. These are some of the latest ideas being tested to combat climate change in an emerging and hotly-debated field called geoengineering. Geoengineering involves use...

Vital Precipitation Could Be Lost Through Climate Geoengineering

[ Watch the Video: Monsoonal Rains Could Shrink Due To Geoengineering ] April Flowers for redOrbit.com - Your Universe Online A new study, led by scientists from the National Center for Atmospheric Research (NCAR), shows that although a significant build-up in greenhouse gases in the atmosphere would alter worldwide precipitation patterns, a widely discussed technological approach to reduce future global warming would also interfere with rainfall and snowfall. The findings, published...

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...

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...

Sunblock For The Earth
2012-10-12 09:46:48

April Flowers for redOrbit.com - Your Universe Online When you want to protect your skin from the harmful rays of the Sun, you employ some sort of sun block. It might be a lotion or a cream; it might even be a shirt or an umbrella to filter the effects. But what would you use to protect the entire planet from the Sun? Apparently that is the question that an increasing number of scientists are trying to answer; ways to temporarily reduce the amount of sunlight reaching the Earth to stave...

A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable. Published today, 31 August 2012, in IOP Publishing's journal Environmental Research Letters, the study has shown that the basic technology currently exists and could be assembled and implemented in a number of different forms for less than USD $5...

Cloud Geoengineering May Help Global Warming
2012-08-21 10:56:29

April Flowers for redOrbit.com - Your Universe Online Imagine futuristic ships shooting salt water into the clouds over the world's oceans to create clouds that reflect sunlight. Sounds like science fiction, but it could be reality before too long. An international team of researchers is taking a second look at this controversial idea to slow global warming effects and has published their concept in this month's Philosophical Transactions of the Royal Society. University of...
