Study: annual climate impact of wild pigs could be greater than 1.1M cars

Green Car Congress

Feral swine are descendants of escaped or released pigs. The researchers used predictive population models coupled with advanced mapping techniques to estimate the climate damage wild pigs are causing across five continents. Feral swine are the same species, Sus scrofa , as pigs that are found on farms.

ARPA-E selects SwRI to create more effective burner to reduce methane emissions

Green Car Congress

Burners currently used on the field commonly perform below target specifications, especially under crosswind conditions, which results in a significant portion of this powerful greenhouse gas escaping into the atmosphere. The three-year, $2.9-million SwRI Research Engineer Luis Gutierrez is working with Prof.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. The study is the first to attempt to account for methane escaping from abandoned mines. Mines are getting deeper every year.

Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

The corresponding climate impacts, however, have been only indirectly evaluated and thus remain largely unquantified. Robert Allen/UCR) Both types of energy—longwave (from Earth) and shortwave (from sun)—escape from the atmosphere more than they are absorbed into it.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climate change have been difficult to calculate.

We Don’t Need a Jetsons Future, Just a Sustainable One

Cars That Think

Much of the motivation behind building new rockets or developing colonies on Mars is wrapped up in the rhetoric of our warming planet being something to escape from. But we can change our attitudes. What's more, we are changing. Climate change is a great example.
