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.,

Bertrand Piccard’s Big Hydrogen Adventure

Cars That Think

He is the quintessential modern explorer, for whom every big mission has a purpose, which generally boils down to environmental and climate-change awareness. IEEE Spectrum interviewed Bertrand Piccard at a pivotal moment in the hydrogen-powered aircraft project, with the plane, called Climate Impulse , about 40 percent built.

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.

Next 10 report finds California must increase GHG reductions to 4.9%/year through 2030 to meet target

Green Car Congress

The largest one-year emissions drop California has ever achieved was at the height of the Great Recession in 2009, when climate pollution fell 6.1%. The fact is, we’ve never come anywhere near cutting emissions five percent in a single year in a period of economic stability—and yet, in order to meet our climate goal by 2030, we have to.

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.

Researchers Finds Lake Tanganyika Has Experienced Unprecedented Warming Over Last Century

Green Car Congress

F), last measured in 2003, is the warmest the lake has been for a millennium and a half. The lake is highly stratified and depends on wind to churn the waters and send nutrients from the depths toward the surface as food for algae, which supports the entire food web of the lake. —Andrew Cohen.
