Ocean acidification takes a toll on California’s coastline at nighttime

A new study, based on the most-extensive set of measurements ever made in tide pools, suggests that ocean acidification will increasingly put many marine organisms at risk by exacerbating normal changes in ocean chemistry that occur overnight. Conducted along California’s rocky coastline, the study from DGE’s Ken Caldeira and Lester Kwiatkowski shows that the most-vulnerable organisms are likely to be those with calcium carbonate shells or skeletons. It is published by Scientific Reports. more »

Greenhouse Gas “Bookkeeping” Turned on Its Head

For the first time scientists have looked at the net balance of the three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—for every region of Earth’s landmasses. They found surprisingly, that human-induced emissions of methane and nitrous oxide from ecosystems overwhelmingly surpass the ability of the land to soak up carbon dioxide emissions, which makes the terrestrial biosphere a contributor to climate change. The results published in the March 10, 2016, Nature, revises our understanding of how human activity contributes to global warming. Co-author Anna Michalak of DGE remarked, “Typically we think of land as a net ‘sink’ of carbon dioxide. But we found that the sign of the human-induced impact is reversed if we also take into account methane and nitrous oxide.” more »

Ocean acidification already slowing coral reef growth

A team of scientists led by DGE’s Rebecca Albright and Ken Caldeira performed the first-ever experiment that manipulated seawater chemistry in a natural coral reef community in order to determine the effect that excess carbon dioxide released by human activity is having on coral reefs. Their results provide evide. more »

Tens of millions of trees in danger from California drought

California’s forests are home to the planet’s oldest, tallest and most-massive trees. New research from Carnegie’s Greg Asner and his team reveals that up to 58 million large trees in California experienced severe canopy water loss between 2011 and today due to the state’s historic drought. Their results are published in Proceedings of the National Academy of Sciences. more »
