Geoengineering is the deliberate and large-scale intervention in the Earth’s climatic system with the aim of reducing global warming. Who should do it and when? Anything done has the possibility of affecting everybody so who should be consulted? Who decides such world spanning concepts? A new study investigated these concerns. The findings are the (more…)
Increasingly warm and humid conditions that are predicted in the coming decades could slash worker productivity 10 percent worldwide by mid-century and could eliminate worker capacity altogether in some regions during the hottest months, a new U.S. study predicts.
In an analysis of labor capacity based on existing (more…)
When global warming is discussed, many will try to predict how much the ice cap will melt and how much the seas will rise. There are many variables in this calculation. A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where (more…)
With policymakers and political leaders increasingly unable to control global climate change, more scientists are considering the use of other engineering approaches other than control at the source to reduce warming impact. The problem is whatever you do, it will have some impact somewhere and somehow. The impact may be good but it also may be bad. University of Iowa (more…)
Researchers from the University of Michigan said this month that the crop of new cars and trucks sold in the U.S. in October are the most efficient ever to hit American roads. Their average fuel was 24.1 mpg combined. That’s a four mile-per-gallon improvement from five years ago.
This gain in fuel efficiency equates to a collective (more…)
Bill McKibben — author, climate activist, and founder of 350.org — is in the midst of a 21-city “Do the Math” tour to build grassroots support for combating climate change. The target of the campaign is the fossil fuel industry, and McKibben and 350.org are calling for universities, colleges, and governments to divest themselves of oil and coal company assets. (more…)
