Study shows impact of global warming on coffee production

Study shows impact of global warming on coffee production

Science
Sept. 11 (UPI) -- A recent study by the University of Vermont found global warming could reduce coffee growing areas in Latin America by as much as 88 percent by 2050.Researchers from the University of Vermont's Gund Institute for Environment found climate change will continue to negatively impact coffee production, as well as bee populations, essential to coffee farming."Coffee is one of the most valuable commodities on earth, and needs a suitable climate and pollinating bees to produce well," Taylor Ricketts, director of the UVM's Gund Institute for Environment, said in a press release. "This is the first study to show how both will likely change under global warming -- in ways that will hit coffee producers hard."The study, published today in the Proceedings of the National Academy of S...
Galapagos seabird's numbers expected to shrink with ocean warming

Galapagos seabird's numbers expected to shrink with ocean warming

Science
Aug. 25 (UPI) -- A new study at Wake Forest University suggests the loss of sardines around the Galapagos Islands because of rising ocean temperatures has had a profound effect on the Nazca booby, and the effect is expected to get worse.The Nazca booby is a tropical seabird whose diet consists primarily of sardines.Rising ocean temperatures around the Galapagos Islands are expected to rise significantly making the water too warm for a key prey species of sardines to tolerate.The study, published Aug. 23 in Plos One, is an analysis of how the absence of sardines has effected the diet, breeding and survival of Nazca boobies. The new study is part of a long-term study at Isla Espanola in the Galapagos Islands for more than 30 years.Researchers found that in 1997 sardines disappeared from Nazc...
Arctic voyage finds global warming impact on ice, animals

Arctic voyage finds global warming impact on ice, animals

Technology
The email arrived in mid-June, seeking to explode any notion that global warming might turn our Arctic expedition into a summer cruise. "The most important piece of clothing to pack is good, sturdy and warm boots. There is going to be snow and ice on the deck of the icebreaker," it read. "Quality boots are key." The Associated Press was joining international researchers on a month-long, 10,000 kilometer (6,200-mile) journey to document the impact of climate change on the forbidding ice and frigid waters of the Far North. But once the ship entered the fabled Northwest Passage between the Atlantic and the Pacific, there would be nowhere to stop for supplies, no port to shelter in and no help for hundreds of miles if things went wrong. A change in the weather might cause the mercury to drop ...
Scientists consider 'cloud brightening' to slow global warming

Scientists consider 'cloud brightening' to slow global warming

Science
July 25 (UPI) -- Scientists at the University of Washington are considering the prospects of a controversial climate change solution called "marine cloud brightening."Most agree the best solution to climate change is the curbing of carbon emissions -- by reducing the burning of fossil fuels, as well as increasing the adoption of renewable energy sources.But if efforts to curb emissions fall short or prove insufficient, emergency solutions may be necessary to avoid the most catastrophic consequences of global warming. Enter marine cloud brightening, a climate engineering solution.Clouds form when water droplets condense on particles in the air and coalesce in the atmosphere. Higher concentrations of particulates allow smaller water droplets to form clouds, yielding bigger, whiter clouds tha...
Global warming, rising seas may encourage parasites

Global warming, rising seas may encourage parasites

Science
July 20 (UPI) -- A study of ancient clam fossils suggests rising seas could once again encourage parasite infestations in brackish water ecosystems.Trematodes, commonly known as flukes, infect mollusks, usually snails, and make their way into the insides of vertebrates who consume infected mollusks. They can cause disease in humans, and blood fluke infections kill an estimated 200,000 people every year.The bodies of the parasitic flatworms don't fossilize, but their presence can be found on the surface of fossil clam shells. Clams form tiny crater-like deposits on their shells at the site of the attempted trematode infestation. The defense mechanism serves as a barometer of the prevalence of the parasite.Recently, researchers analyzed dozens of clam fossils excavated in sediment cores dril...
