Plants help slow warming - but there's a trade-off
2013-04-28 19:10:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: The fragrant smell of the trees is one of the nicest things about taking a walk in the woods. But the organic compounds trees pump out don't just register well with our noses: they also help cool the climate by encouraging clouds to form. As plants respire, they emit chemicals called volatile organic compounds. In the atmosphere, these VOCs can interact with other chemicals to form particle "seeds" that clouds can grow around. Climate models predict that the clouds seeded by plant respiration...

Guy Stewart Callendar: Global warming discovery marked
2013-04-26 14:24:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Seventy-five years ago an amateur scientist made a breakthrough discovery in the field of climate change. Guy Stewart Callendar linked global warming to CO2 emissions but his work went largely unnoticed at the time. Now the anniversary of his discovery has been commemorated by two leading climate scientists. Prof Phil Jones, from the University of East Anglia in Norwich, and Dr Ed Hawkins, from the University of Reading, have published a paper looking at Callendar's legacy. Prof Jones...

A way to curb global warming: Suck carbon emissions right out of the air?
2013-04-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Efforts to combat global warming, triggered and reinforced by rising levels of carbon dioxide as humans burn fossil fuels and convert forests to farmland, largely focus on preventing CO2 from entering the atmosphere in the first place. But small groups of researchers are pursuing a complementary approach. They are looking for ways to remove CO2 already in the air. On small scales, the approach has been used since the 1930s at dry-ice facilities, as well as to scrub CO2 from the air on submarines...
