Scientists find night-warming effect over large wind farms in Texas

Green Car Congress

Large wind farms in certain areas in the United States appear to affect local land surface temperatures, according to a paper published in the journal Nature Climate Change. Night-time land surface temperature differences near wind farms between 2010 and 2013. Nature Climate Change. Credit: Liming Zhou et al.,

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

In climate models, if you simulate the world with sulfur emissions from shipping, and you simulate the world without these emissions, there is a sizable cooling effect from changes in the model clouds due to shipping. F), a change that the Intergovernmental Panel on Climate Change projects would have significant societal impacts.

2009-2010 El Niño Indicators Strong, Pacific Ocean Warming Continues

Green Car Congress

Australia’s Bureau of Meteorology (BOM) reports that multiple indicators continue to show a strong El Niño building in the tropical Pacific Ocean this season, as predicted by a majority of climate models. Trade winds are also weaker than normal across the Pacific, reducing heat discharge from ocean water. F) above average.

CE Delft Study Finds Lower Highway Speed Limits Could Result in Significant Reductions in CO2 from Road Transport; Encouraging Modal Shifts and Land Use Changes

Green Car Congress

Based on the law of constant travel time budget, the average travel time elasticity of the amount of kilometres equals -1, (average for all modalities) (Van Wee, 1998; Pfleiderer, 2003). Fuel consumption of a car increases at higher speeds, the main reason being that with increasing speed the wind resistance increases exponentially.

UK needs step change in climate action

Green Cars News

The UK needs to implement a step change to reduce carbon emissions, the first annual report from the Committee on Climate Change concludes. The committee which is responsible for reporting annual emission reductions in the UK, states that in the five years between 2003 to 2007 emissions reductions averaged 0.5 per cent per annum.

Studying Climate Change with an Ice Radar Drone

Cars That Think

It’s –27 °C, dipping below –40 °C with wind chill—well below the operating temperature of most of the commercial equipment we brought for this expedition. And the data that Peregrine will gather will help scientists to understand how these critical areas will respond to climate change. Thomas Teisberg, an electrical engineering Ph.D.

New NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning

Green Car Congress

In the summer, wind and ocean currents cause some of the ice naturally to flow out of the Arctic, while much of it melts in place. In 2003, 62% of the Arctic’s total ice volume was stored in multi-year ice, with 38% stored in first-year seasonal ice. Yi (2009) Thinning and volume loss of the Arctic Ocean sea ice cover: 2003–2008.
