UCLA/LLNL study concludes most climate models overestimate increase in global precipitation due to climate change

Green Car Congress

UCLA and Lawrence Livermore researchers have found that most climate models overestimate the increase in global precipitation due to climate change. Conveniently, this quantity can be measured from space, allowing the team to assess how well the models capture the physics controlling changes in global precipitation.

Rapid Ecosystem Changes in Arctic Associated with Climate Change May Foreshadow Global Environment of the Future

Green Car Congress

The rapid recent climate change in the Arctic has “ severely perturbed ” Arctic ecosystems and the trophic relationships that structure them, according to a paper published 11 September in the journal Science by an international team of 25 scientists. Heterogeneity as a buffer against climate change in the Arctic.

Heat Pumps—The Well-Tempered Future of A/Cs

Cars That Think

Heath has great job security: half of Phoenix residents are at risk of an emergency room visit or worse if their electricity fails during a future heat wave, according to a recent study. In other words, an incremental efficiency improvement in heating will have a much bigger overall impact on energy demand and therefore climate change.

Scientists call for careful use of time scales, reference dates and statistical approaches in analyzing climate change trends to avoid distortion and hampering of response

Green Car Congress

Demonstrating that the use of different time scales, reference dates, and statistical approaches can generate highly disparate results in climate reports, scientists at the University of Alaska Anchorage argue that careful use of these tools is critical for correctly interpreting and reporting climatic trends in Alaska and other polar regions.

Volkswagen customers in Germany ordering more diesel vehicles; share of 43% in 2018, vs. 39% in 2017

Green Car Congress

Given its high efficiency and its performance and in light of climate change, the diesel engine will remain an important technology for years to come, especially for those who travel long distances. Demand for diesel cars was particularly strong among private customers, where the share almost doubled from 15% in 2017 to 27% last year.
