The Iceland volcano that’s putting a halt to so much European air travel might not have as much of an impact on carbon dioxide emissions and climate … for now. As this fascinating graphic from Information is Beautiful indicates, the amount of carbon being spewed out by Eyjafjallajökull is minuscule

Imagine you and your office mates are trying to plan a really special party for a longtime co-worker who’s about to retire. The group of you has met after work, oh, say, a half-dozen times, but you still can’t all agree on the best type of shindig. Barbecue

And so another geoengineering fix for climate change that sounds great in theory bites the dust on closer examination. The fix in question seems promising at first glance: pump nutrient-rich deep ocean water to the surface, where it can provide a hearty food source for algae. The algae bloom in

How are geoengineering fixes for climate change like seatbelts in an automobile? According to top climate scientist Ken Caldeira, tinkering with the climate might help keep us safe, but we’d better be sure the geoengineering “seatbelt” actually works before we start driving. The top priority for dealing with climate

The Royal Society is set to release a major new policy report on geoengineering the climate in London tomorrow. Geoengineering the climate: science, governance and uncertainty will make recommendations “to ensure that any geoengineering activities are managed responsibly at national and international levels, and do not detract from wider efforts

Is it true? Could Bjørn Lomborg — long a favourite of climate change sceptics for his view that the fight against global warming was too costly to be worth the effort — now have joined the Al Gore/James Hansen “We must act now” camp? Colour us highly sceptical. We’ll give

Geoengineering strategies to curb global warming may offer advantages in combating temperature rise, but could also significantly damage the Earth’s eco-systems, according to climate scientists at the Met Office Hadley Centre. Their research was published recently in the Journal of Geophysical Research. One geoengineering proposal suggests we deliberately brighten

Seeding the upper atmosphere with particles could help curb climate change, but it could also have the unwanted effect of cutting solar energy production by as much as one-fifth, according to a new study from the US National Oceanic and Atmospheric Administration. In the wake of as-yet unsuccessful efforts to

Various geoengineering schemes show promise of reducing the impact of global climate change, but carry risks and limitations as well, according to a first-ever comprehensive assessment by researchers at the University of East Anglia. Among the researchers’ findings: * Enhancing carbon sinks around the globe could help bring down carbon dioxide
