Offshore wind in the US has had to fight to exist for a long time.  The Cape Wind project in Nantucket Sound off the coast of Cape Cod was envisioned over 20 years ago as a 1.5-gigawatt wind farm.  Years of legal battles and other controversies saw the project start and stop multiple times with […]

Globally, freshwater lakes and reservoirs hold 87% of the planet’s liquid freshwater, making them a valuable resource for both people and wildlife.  Despite their value, the long-term trends and changes to water levels of lakes have been largely unknown – until now. According to a new assessment recently published in the journal Science, more than […]

The part of the atmosphere closest to the Earth’s surface has been warming since the Industrial Revolution.  This warming is associated with increasing amounts of carbon dioxide as well as other human-made chemicals that have been changing the makeup of the atmosphere. Climate change is generally thought about in terms of the lowest regions of […]

Climate change is creating a cascade of effects in the world’s oceans.  Not only are ocean temperatures on the rise, but oceans are becoming more acidic, and oxygen deprived.  The warming temperatures and acidification have grabbed headlines and prompted academic research. Declining oxygen levels have not garnered as much attention.  But they spell bad news […]

In climate science, tipping points are critical thresholds that, once crossed, lead to large and often irreversible changes in the climate system. For example, surpassing a 1.5 degree C rise in global warming has long been considered a tipping point for the planet.  According to a new study led by researchers from University College London, […]

El Niño, a weather phenomenon triggered by warm waters in the eastern Pacific, is likely to return this year, according to the World Meteorological Organization.  The Pacific has been in the cooler La Niña phase for the past 3 years, which is unusual, but that appears to be coming to a close.  According to the […]

In the Back to the Future films, Doc Brown ran his DeLorean time machine on food scraps.  It was a fun bit of science fiction.  But researchers at the University of British Columbia Okanagan in Canada are investigating the potential for using food waste to generate power. Food waste is not a candidate to replace […]

We hear a lot about artificial intelligence these days.  ChatGPT has found its way into education, technology, and many other aspects of life.  It and its brethren are a source of fascination, enthusiasm, and even fear.  Many of us have given queries to the bot to see what kind of results we can obtain.  But […]

The world is experiencing a decline in overall insect populations as well as a collapse in insect diversity.  A recent special issue of the journal Biology Letters discusses the major causes of this alarming trend. According to the study, the primary causes of the worldwide decline in insect biomass are land-use intensification in the form […]

There are currently only two small offshore wind farms operating in the United States, but there are now several more under construction or in the permitting process.  Substantial wind farms are expected to come online over the next five years off the coasts of Virginia, New Jersey, Massachusetts. North Carolina, Delaware, Rhode Island, and New […]
