AUSTIN, Texas — Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists from The University of Texas at Austin advise.

Camille Parmesan, Michael C. Singer and their coauthors published their commentary online this week in Nature Climate Change.

“Yes, global warming is happening. Yes, it is caused by human activities. And yes, we’ve clearly shown that species are impacted by global warming on a global scale,” says Parmesan, associate professor of integrative biology. (more…)

Berkeley Lab Scientists Achieve Breakthrough in Nanocomposite for High-Capacity Hydrogen Storage

Since the 1970s, hydrogen has been touted as a promising alternative to fossil fuels due to its clean combustion —unlike the combustion of fossil fuels, which spews greenhouse gases and harmful pollutants, hydrogen’s only combustion by-product is water. Compared to gasoline, hydrogen is lightweight, can provide a higher energy density and is readily available. But there’s a reason we’re not already living in a hydrogen economy: to replace gasoline as a fuel, hydrogen must be safely and densely stored, yet easily accessed. Limited by materials unable to leap these conflicting hurdles, hydrogen storage technology has lagged behind other clean energy candidates. (more…)

Global Rivers Emit Three Times IPCC Estimates of Greenhouse Gas Nitrous Oxide

*Waterways receiving nitrogen from human activities are significant source*

What goes in must come out, a truism that now may be applied to global river networks.

Human-caused nitrogen loading to river networks is a potentially important source of nitrous oxide emission to the atmosphere. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. (more…)
