Rather than being a paradise on earth for believers in his utopia, the land he purchased has become a refuge . . . → Read More: Preserving Paradise: SDSU i…

Researchers are using seagrass from Newport Beach and other locations across the state to see if the salt-water flowering plant can fight ocean acidity, which they say could possibly curb the effects of climate change. Ocean acidification is a global problem that occurs when seawater takes in carbon dioxide from the atmosphere, making it difficult . . . → Read More: Can eelgrass in Newport Beach …

http://www.nature.com/nature/journal/v537/n7622/full/537625a.html Carbon emissions from the Arctic tundra could increase drastically as global warming thaws permafrost. Clues now obtained about the long-term effects of such thawing on carbon dioxide emissions highlight the need for more data.

http://inewsource.org/2016/09/28/san-diego-forest-loss/ The forests of San Diego County that have shaded 500 generations of local people and provided pine needle bedding, oak woodland and spiritual renewal could disappear. Overly intense fires in quick succession, along with drought, borer insects and climate extremes is laying waste to trees and creating a hostile environment for regrowth. Trees…

Bad news: Scientists say we could be underestimating Arctic methane emissions Arctic permafrost has become a recent star in the climate change conversation, capturing the attention of scientists, activists and policymakers alike because of its ability to emit large quantities of carbon dioxide as well as methane — a particularly potent though relatively short-lived greenhouse . . . → Read More: T…

GCRG was awarded a grant by the US National Science Foundation for the proposal, “Methane loss from the Arctic: towards an annual budget of CH4 emissions from tundra ecosystem across a latitudinal gradient” (PI: Donatella Zona). In this research project we will measure CO2 and CH4 fluxes across a latitudinal transect in the arctic . . . → Read More: GCRG awarded NSF grant towards the annual budge…

Indonesia has the largest tropical peats, ranging from 18 to 27 million hectares. It is estimated that about 12 million hectares of these peats have been disturbed and substantially drained in order to lower water table depths which are required for agricultural uses (i.e. rice paddy, industrial pulp, and recently oil palm plantation). Drained and . . . → Read More: Impacts of Conversion and Drai…
