For more than a century scientists have known that Earth’s ice ages are caused by the wobbling of the planet’s orbit, which changes its orientation to the sun and affects the amount of sunlight reaching higher latitudes, particularly the polar regions.
As demand climbs for more fuel-efficient vehicles, knowledge compiled over several years about diesel engines and a new strategy known as “low-temperature combustion” (LTC) might soon lead auto manufacturers and consumers to broader use of cleaner diesel engines in the United States.
Northrop Grumman Corporation has achieved its inaugural greenhouse gas (GHG) reduction goal of 25 percent in three years, two years ahead of plan. In 2012, the company realized a 25.3 percent GHG intensity reduction from its 2008 baseline, resulting in a 26.9 percent absolute emissions reduction.
What’s good for adults is not always best for the young, and vice versa. At least that is the case with song sparrows and how they experience the effects of climate change, according to two recent studies by scientists at the University of California, Davis, and Point Blue Conservation Science.
When Ken Davis, Penn State professor of meteorology, used to think about climate change he looked at it as a scientific problem, with an economic dimension.
Climate-KIC, Europe's largest public-private innovation partnership working to address the challenge of climate change, has awarded more than £125,000 through the Climate Market Accelerator (CMA) programme to a project aimed at shifting electricity usage towards renewable energy at off-peak times, supported by the National Physical Laboratory (NPL).
The United States Agency for International Development’s (USAID) Pacific Vocational Training and Education for Clean Energy program has received a USD $394,000-grant contribution from New Zealand’s Ministry of Foreign Affairs and Trade (NZ MFAT) to expand the existing two-year program in the Pacific Islands.
The global treaty that headed off destruction of earth's protective ozone layer has also prevented major disruption of global rainfall patterns, even though that was not a motivation for the treaty, according to a new study in the Journal of Climate.
The planet is undergoing one of the largest changes in climate since the dinosaurs went extinct. But what might be even more troubling for humans, plants and animals is the speed of the change. Stanford climate scientists warn that the likely rate of change over the next century will be at least 10 times quicker than any climate shift in the past 65 million years.
With the “green” reputation of large hydroelectric dams already in question, scientists are reporting that millions of smaller dams on rivers around the world make an important contribution to the greenhouse gases linked to global climate change. Their study, showing that more methane than previously believed bubbles out of the water behind small dams, appears in ACS’ journal Environmental Science & Technology.
