Peatlands contain peat soil, which is wet, thick, and made of partially-decomposed plant materials. The International Peatland Society (IPS) cover approximately 3% of the Earth’s surface. Tropical peatlands in Asia, the Caribbean, Central and South America, and Southern Africa contain 10-12%of the total peatland resource. Peatlands are also extremely valuable ecosystems because they foster biodiversity,…

Blue Carbon: A Solution

seagrass_in_north_west_tunisia

Coastal ecosystems such as tidal salt marshes, seagrass meadows, and mangrove forests, are “blue carbon ecosystems” because they act as carbon sinks. Blue ecosystems have the ability to sequester copious amounts of carbon. However, if they are destroyed, they increase GHG emissions. Scientists estimate approximately 1.02 billion tons of carbon dioxide is emitted per year…

Decarbonization or Climate Neutrality? Which is the Better Path to 2°C? Is There Even a Difference?

http://buildingindustry.org/one-million-tonnes-of-co2

In order to keep global temperatures under 2°C, the threshold generally accepted as the best way to avoid the most catastrophic impacts of climate change, there must be a limit on cumulative CO2 emissions. For those of you not tracking mitigation negotiations closely at COP21, there is some hot debating surrounding long-term signals maintaining this threshold….

Carbon Capture and Sequestration – A Cautionary Tale

www.energydigital.com

“That is not what the IPCC says.”   At an event promoting carbon capture and sequestration technology (CCS), an audience member who co-authored a section of the IPCC Synthesis challenged the assertion that carbon capture and sequestration is a necessary technology to reduce greenhouse gas emissions. In doing so, he highlighted the tension between competing…

Reading Between the Lines on the US-China Climate Agreement

China-deal-638x532

As noted on this blog yesterday, at the close of the recent Asia-Pacific Economic Cooperation Summit in Beijing, President Obama and President Xi Jinping issued a joint US-China “announcement” on climate change.  The United States announced that it intends to achieve economy-wide emissions reductions of 26%-28% below 2005 levels by 2025, while China for the…

Are deserts carbon sinks?

desert

Can arid regions – specifically deserts – act as carbon sinks?  This study, led by Professor David Evans of Washington State University and published in the current edition of Nature Climate Change, offers this conclusion:  “Results provide direct evidence that CO2 fertilization substantially increases ecosystem C storage and that arid ecosystems are significant, previously unrecognized,…
