What are main types of carbon capture and storage technology?

2014-08-15 03:04:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: There are three main types of carbon capture and storage (CCS) technology that could eventually help reduce emissions from power stations and other industrial sites: pre-combustion, post-combustion and oxyfuel. Post-combustion In this method, CO2 is separated from the flue gas of the power station by bubbling the gas through an absorber column packed with liquid solvents (such as ammonia). In the most widely used system, once the chemicals in the absorber column become saturated, a stream of...

Man-made warming becomes main cause of glacier retreat, study says

2014-08-14 20:04:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: Man-made greenhouse gas emissions have become the dominant cause of melting in glaciers from the Alps to the Andes that is raising world sea levels, a study said on Thursday. Human emissions accounted for an estimated 69 percent of loss of ice from glaciers from 1991-2010, overtaking natural climate variations that had been the main driver of a retreat since the mid-19th century, researchers wrote in the journal Science. Until now, scientists have struggled to quantify the impact of human behavior...
