The picture below shows Pinyon pine forests in New Mexico – and the progressive consequence of the large drought that hit western North America between 2000-2004. The left image is from 2002 and already shows some browning of pine trees halfway … Continue reading →
A group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation.
In this zeolite structure, the arrangement of oxygen atoms (red) and silicon atoms (tan) influences the regions in the pores (colored surface) where CO2 can be captured.
A detailed analysis of more than 4 million absorbent minerals has determined that new materials could help electricity producers slash as much as 30 percent of the “parasitic energy” costs associated with removing carbon dioxide from power plant emissions.
The research by scientists at Rice University, the University of California, Berkeley, Lawrence Berkeley National Laboratory (LBNL) and the Electric Power Research Institute (EPRI) was published online this week in the journal Nature Materials (“In silico screening of carbon-capture materials”).
A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In subsequent tests, these methyl ketones yielded high cetane numbers – a diesel fuel rating comparable to the octane number for gasoline – making them strong candidates for the production of advanced biofuels.
The Sahel, one of the hottest regions on Earth ranging from the Atlantic coast south of the Sahara Desert to the Red Sea to the east and the Horn of Africa to the southeast, is getting drier and drier and … Continue reading →
Whom would you rather believe? The world’s three best-established atmospheric research institutes – or a Berkeley dream team with the current Physics Nobel Prize laureate, backed up by the largest collection of land temperature measurements ever? So sorry to confuse … Continue reading →
