Public has strong negative views on climate engineering
Can climate hacking slow the pace of global warming?
By Summit Voice
FRISCO — The concept of climate hacking may be popular in some intellectual circles, but the public in general — at least in New Zealand and Australia — is skeptical that we can engineer our way out of the global warming crisis.
Researchers with the University of Southampton and Massey University (New Zealand) recently tried to systematically evaluate public reaction to climate engineering, which involves deliberate large-scale manipulation of the environment to counteract climate change.
The results, published in Nature Climate Change, suggest that people have a negative view of such efforts, perhaps instinctively understanding that such efforts will more than likely have unintended consequences — Illustrated by one recent study showing potential disruption of monsoon rains.

New policy brief outlines benefits of mangrove conservation

SUMMIT COUNTY — Conversion of mangrove forests is taking a huge toll on coastal ecosystems, an international team of researchers said, warning that replacing tidal forest with shrimp farms and other forms of development is a bad economic tradeoff both short and long-term.
“The benefits of this industry have too often been short lived due to poor planning with ponds being abandoned when pollution or disease take hold, leaving unproductive saline pools and depleted coastal fisheries,” said Hanneke Van Lavieren, a United Nations University scientist who was the lead author of the recent policy brief.

There are about 150 carbon-sequestration projects under way across the U.S.
Ethanol byproducts to be pumped deep into a sandstone formation
By Summit Voice
SUMMIT COUNTY — Carbon dioxide byproducts from an Archer Daniels Midland Company ethanol plant will be injected 7,000 feet deep into an Illinois sandstone formation in the first million-ton carbon sequestration demonstration in the U.S.
Although geo-engineering is not without controversy, top administration officials say geologic storage of CO2 could be an important part of climate mitigation strategies.
The CO2 will be captured during the ethanol fermentation process and compressed into a dense liquid for permanent storage beneath several layers of shale that are dense enough to cap the greenhouse gas. Continue reading
