As the years roll by without sufficient progress in reducing carbon dioxide emissions, the need for technologies that can capture CO2 from its sources or remove it from the air becomes stronger and stronger.  People have developed various ways to capture carbon dioxide, but to date, they generally suffer from some combination of being too […]

According to the World Food Programme, a record 349 million people across 79 countries are facing acute food insecurity.  This constitutes a staggering rise of 200 million people compared to pre-pandemic levels.  Nearly one million people globally are fighting to survive in famine-like conditions, which is ten times more people than just five years ago.   […]

According to a new report from the Rocky Mountain Institute, a nonprofit that studies the energy transition, we have reached a pivot point in which fossil fuels have peaked in their use for producing electricity and are about to enter a period of decline. The report makes the case that wind and solar power are […]

Recent satellite observations of the sea ice in the Antarctic found the lowest level of ice cover ever seen in the forty years that these observations have been made.  As of February 8th, there were only 849,000 square miles of the Southern Ocean covered with ice.  The previous record low was measured last February 24th […]

Big cats are among the most widely recognized and admired animals in the world. But these charismatic predators face many and varied threats, including the loss of habitat and prey, conflicts with humans, poaching, and the illegal wildlife trade. Researchers from the University of Reading in the U.K. have studied the fortunes of 50 species […]

Global steel production has been rising for decades.  Because steel corrodes over time, part of the demand for more steel comes from the need to replace the steel used in construction materials – in everything from bridges to cars – that has become corroded over time.  Studies have estimated that the economic cost of corrosion […]

The US has seen annual reductions in honey bee colonies since 2006.  According to the USDA, there are many factors that have contributed to the decline.  These include parasites, pests, insecticides, disease, and a phenomenon called Colony Collapse Disorder in which worker bees abandon a hive and leave behind the queen. One of major threats […]

A study by University of Michigan researchers found that about 90% of U.S. households would save money on fuel costs by owning an electric car rather than a gas-powered car.  So apart from the environmental benefits of electric cars, there are real economic benefits as well. Both the price of gasoline and the price of […]

The Ocean Cleanup is a non-profit organization, founded in 2013 by Dutch inventor Boyan Slat, to develop and scale technologies to rid the world’s oceans of plastic.  It is an organization that proudly declares that its primary aim is to put itself out of business by successfully cleaning up the oceans. A major activity of […]

California experienced its wettest 10-day period in 25 years as a result of a series of storms driven by atmospheric rivers in January.  The Rocky Mountains got buried in snow from the same weather pattern.   For the drought-stricken West, the storms were good news.  But they are not the cure for what’s been ailing the […]
