Some aircraft designers think outside the box to improve efficiency
Posted on 24 Mar 2011 by Thomas H. Clarke, Jr.

Concern has been expressed in recent years over the contribution of aircraft to GHG emissions. Some airlines have gotten favorable publicity for experimenting with bio-derived fuels. But, what if aircraft were to target reducing fuel consumption by half... Read More

Natural gas development poses a risk of enhancing GHG emissions due to "leakage", note new studies
Posted on 11 Apr 2011 by Thomas H. Clarke, Jr.

Several prior posts have noted the greenhouse impact of methane (aka natural gas); it has many times the warming effect as carbon dioxide (CO2), which seems to be the focus of so much discussion about global warming. The posts have focused on the numerous... Read More

Trees damaged by bark beetles slow their uptake of CO2 for up to a century
Posted on 20 Apr 2011 by Thomas H. Clarke, Jr.

As noted in prior posts, bark beetles damage large forest areas, often killing or causing the death of 50% to 80% of mature trees. As these trees decompose, they release CO2, adding to the atmospheric burden of GHG's. New research has identified additional... Read More

Data from crop trials demonstrates threat climate change poses to crops
Posted on 27 Mar 2011 by Thomas H. Clarke, Jr.

Serendipity has helped more than a few scientists with insights and discoveries. Researchers were chatting, and realized that data from work one of them was focused upon various crop trials spread across southern and eastern Africa, if correlated with... Read More

Because some ships may be less carbon intensive than others, customers can influence emissions
Posted on 16 Dec 2010 by Thomas H. Clarke, Jr.

"If the shipping industry were a country, it would be the sixth-biggest industrial carbon emitter in the world. Whereas big countries have plans for cutting emissions, shipping does not. The UN climate talks in Cancún are unlikely to change... Read More
