The changing Arctic climate has had a drastic effect on its seabirds.  In fact, seabirds worldwide are in crisis, with global populations plummeting nearly 70% over the past 70 years as a result of climate change, over-fishing, habitat loss, and other human impacts on their environment. Above the Arctic circle in Norway, seabird behavior has […]

Over 300 coal-fired power plants in the US have stopping burning coal over the past decade.  Only about 224 plants still produce power by burning coal.  As a result, a new sort of recycling industry is taking shape:  repurposing of coal plants. Across the country, utilities are finding ways to redevelop these facilities.  Some are […]

Researchers from the University of Texas at Austin, the U.S. Fish and Wildlife Service, and Florida State University have published a paper presenting evidence of significant and previously undetected concentrations and fluxes of dissolved organic matter entering Arctic coastal waters.  The source of the organic matter is groundwater flow atop the frozen permafrost.  The groundwater […]

As people all over the world shelter in place and much ordinary commerce and other activities have ground to a halt, there have been big changes in energy usage.   With production halted, offices shut down, schools closed, and public transport operated on reduced timetables, the demand for energy has decreased dramatically. In Europe, as a […]

According to a new study led by researchers from the University of California – Davis, conserving natural habitat around strawberry fields can protect farmers’ yields, their bottom line, and the environment.  The study also suggests that conserving natural habitat in this way has no detectable threat to food safety.  In this study, which was recently […]

Tropical forests are an important part of the global carbon cycle because they take up and store large amounts of carbon dioxide.  Because of this, deforestation in the Amazon and other tropical forests is a major contributor to the growing CO2 levels in the atmosphere. Therefore, climate models need to accurately take into account the […]

There are articles in the media all the time questioning whether electric cars are really better for the environment than those powered by fossil fuels.  The usual argument is that once emissions from vehicle production and electricity generation are taken into account, electric cars are no greener than gas cars, or even worse for the […]

Permafrost is frozen ground – a combination of soil, rock, sand, and ice – that remains at or below freezing for at least two consecutive years.  Approximately 25% of the land in the Northern Hemisphere meets this criterion, the majority of which can be found in northern Russia, Canada, Alaska, Iceland, and Scandinavia. But as […]

More than 55 million adult Americans feed wild birds and along the way spend more than three billion dollars a year on bird food as well as nearly a billion on bird feeders, bird baths, bird houses and other bird feeding accessories.  Feeding birds is a very popular hobby in both the United States and […]

More than 100,000 miles of U.S. rivers and streams are polluted by nitrogen and phosphorus, mostly from agricultural runoff.  In the past, forests grew naturally alongside these waterways and helped stabilize stream banks and decrease flooding while trapping and filtering pollutants.  But most of these forests have been cut down to make way for towns, […]
