Carbon Sequestration in Salt Marshes

Posted 3 years 2 months ago

The importance of the world's rainforests, and to some extent the mangroves, as storage sinks for atmospheric are carbon well-known. But salt marshes, too, are extraordinarily efficient mechanism for photosynthesis and the production of biomass that work together to sequester carbon at a high rate. So disappearing wetlands along the coast present much more peril than loss against storm surge, which itself plays significant part in their role in an ecosystem.

Now, Deepak Mishra, associate professor in the department of geography, has developed tools and techniques to map carbon...

Shepherd: Lessons on climate from Ebola outbreak

Posted 3 years 3 months ago

Athletics Association Professor in the Social Sciences and nationally-recognized expert on climate Marshall Shepherd took to the pages of the Washingtom Post last week to point out connections between the latest Ebola outbreak and the challenges presented by climate change:

However, before I mention these parallels, I want to establish that I trust the expertise and knowledge of those in the infectious disease and public health communities, respectively. As an expert in weather and climate, I often see  “arm-chair expertise” or Ph.D.’s from other disciplines, questioning weather...

Anthropocene: Economics of the transition

Posted 3 years 3 months ago

Something that often goes missing in conversations on, much less debates about, what to do about climate change is optimism. If, for example, a discussion of the economics of the transition to an industrial model from the agricultural age had occured, there would have been great gnashing of teeth but a convincing case could have been made, though likely with some strict limitations toward eventual consequences, if these could have been imagined. The point is, the same dynamics are at play when trying to imagine the transition away from a dependence on fossil fuels; we're limited by how...

Coming on the heels of the People's Climate March yesterday in NYC, the next installment of the Anthropocene Lecture Series this week promises to be timely and informative:

The 21st century is the first urban century in the history of humankind.  Current projections suggest that 60-80% of the world population will live in urban settlements by the end of this century.  The urban environment alters climate, weather, and natural cycles (e.g.. water and biogeochemical).  Such interactions also influence human health, energy consumption, transportation, and planning.  Influential at...

Shepherd named Captain Planet Protector

Posted 3 years 5 months ago

The award sounds funny, but the prestigious Captain Planet Foundation has honored Marshall Shepherd for his very serious efforts on educating the public about climate change: 

Marshall Shepherd is a Captain Planet Protector of the Earth, according to the Captain Planet Foundation, which recently added him to a list of outstanding real-life environmental superheroes.

Shepherd, the UGA Athletic Association Professor in the Social Sciences, will receive the award at the annual Captain Planet Foundation Benefit Gala Dec. 5 at the InterContinental Buckhead Atlanta hotel. Other...
