By Alyssa Moir, Marten Law Group PLLC In this Emerging Issues Commentary, Alyssa Moir writes that the Environmental Protection Agency (EPA) and the National Highway Transportation Safety Administration (NHTSA) have jointly proposed the first-ever fuel economy and greenhouse gas (GHG) standards for...

An entirely new carbon sink in the oceans may have been discovered

One of the themes that has run through prior posts is to note that our understanding of the carbon cycle may leave more than a little to be desired. Such lack of understanding may explain why the impacts of global warming are, in some cases, more severe than anticipated, and in some cases less severe...

A Closer Look at Climate Change Skepticism -- An Interesting Assessment

In an interesting assessment, the author notes: "Debate over climate change is nothing new. Scientists have been arguing about whether greenhouse gases released by human activity might change the climate since the late nineteenth century, when Swedish chemist Svante Arrhenius first proposed that...

Lakes across the globe are warming up

Throughout the past quarter-century, inland lakes have been experiencing a small, steadily rising nighttime fever. Globally, the average increase has hovered around 0.045 degrees Celsius per year, but in some regions the increase has been more than twice that - or about 1 °C per decade. In some regions...

The trend toward use of heavier crudes increases the carbon footprint of petroleum products

Heavier crudes are, by definition, more viscous. The also contain greater amounts of sulfur, which must be removed because of the adverse impact of sulfur on various catalysts used in the refining process. The sulfur content of fuel is also controlled because of its impact on particulate generation....

U.S. High Court Agrees To Take Up Case Over Energy Companies' Emissions

WASHINGTON, D.C. -- (Mealey's) The nation's high court on Dec. 6 granted a petition for certiorari filed by five power companies seeking review of a Second Circuit U.S. Court of Appeals ruling reinstating two Clean Air Act (CAA) lawsuits brought by eight states seeking to limit the companies'...

Because some ships may be less carbon intensive than others, customers can influence emissions

"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 that. But customers, who indirectly pay for shipping...

California sets forth indicators of disproportionate impacts of climate change on environmental justice communities

To assist Cal-EPA with the examination of potential environmental justice concerns associated with climate change, Cal-EPA requested the Office of Environmental Health Hazard Assessment (OEHHA) [best known for its role in setting drinking water related Public Health Goals and in overseeing much of the...

Movement of corals around Japan provides evidence of global warming

Prior posts have noted that in terms of ascertaining evidence of global warming, it may be worthwhile to assess the numerous studies of various potential indicators (e.g., migration patterns, drought, relocation of biota). Add another indicator. A new study of reefs around Japan reveals that a handful...

Assessment of preliminary data indicates that 2010 ties record for warmest year

NASA and the National Oceanic and Atmospheric Administration released their analyses of global surface temperature data for 2010. Both found that 2010 was slightly warmer than 2005, but that the difference was not statistically significant. Combined land and ocean surface temperatures across the globe...

Some aircraft designers think outside the box to improve efficiency

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, or more. That will require some radical rethinking...

Data from crop trials demonstrates threat climate change poses to crops

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 local weather conditions (other than drought), could...

Acidification of Oceans May Affect the Brains of Fish

Yesterday's post noted some of the adverse consequences that are likely to arise from acidification of oceans. Another recent study shows that such acidification can influence the behavior of fish because of impacts on their brains; the response of nerve cells can be reversed as acidifying seawater...

Can addressing air pollution decrease global warming? You betcha

Prior posts have noted the adverse health impacts from small particles, often referred to generally as PM10 and/or PM2.5. Prior posts have also noted the adverse impact of soot on global warming, which because it is black and absorbs heat warms up the atmosphere and whatever it is coating (e.g., glaciers...
