In January 2025, a series of destructive wildfires in the Los Angeles metropolitan area and San Diego County killed as many as 440 people, forced more than 200,000 to evacuate their homes, destroyed more than 18,000 homes and structures, and burned over 57,000 acres of land.  A study by the nonpartisan California Policy Lab found […]

Geoengineering refers to a wide range of mechanical or chemical methods aimed at deliberately changing the global climate system.  It includes a number of unproven concepts, one of which is intentionally polluting the upper atmosphere with thousands of tons of artificial particles such as chemical sprays or mineral dust.  This is referred to as solar […]

Hanauma Bay is a marine sanctuary near Honolulu that is a popular snorkeling spot and is home to vibrant marine life and well-preserved corals. Its popularity grew in the 1970’s and 1980’s and its visitor attendance peaked at an estimated 10,000 people a day. A new management plan in 1990 reduced visitation, improved facilities, established […]

Polyethylene Terephthalate (otherwise known as PET plastic) is a clear, strong, lightweight plastic used for food and beverage containers, textiles, and many other things.  It is one of the most pervasive forms of plastic piling up in the world’s oceans, in landfills, and elsewhere.  Getting rid of it is a real challenge. Scientists at the […]

The current administration has essentially declared war on renewable energy.  President Trump stated recently that his administration will not approve solar or wind power projects.  Renewable companies are unlikely to receive permits that were once a normal course of business. Now, the United States is likely to struggle to meet its growing demand for electricity […]

Honeybee populations have been declining for a combination of interacting factors.  There is the parasitic Varroa mite that spreads disease; there is widespread exposure to pesticides; there is diminishing natural forage and nesting habitats as land is developed; and there is climate change.   Researchers at Oxford University looked at the impact of climate change and […]

The Middle East is known for its vast petroleum resources and oil has been its primary source of wealth.  But the desert region is now becoming a significant center for solar energy as well.  The world’s largest single-site solar park is the Mohammed bin Rashid Al Maktoum Solar Park, located in the United Arab Emirates. […]

Planting trees is a key strategy in the fight against climate change.  Trees absorb carbon dioxide, regulate temperature, support biodiversity, and improve air and water quality, offering benefits that extend well beyond their boundaries. But according to a new study by researchers from University of California – Riverside, where those trees are planted makes a […]

Tens of millions of bison once migrated across the United States in enormous herds; tribal oral histories speak of it taking days for an entire herd to pass by.  These herds shaped the landscape and performed many ecosystem functions.  By the 1890s, the bison population had plummeted to fewer than 1,000 individuals.  Since then, dedicated […]

Lead pipes were once widely used in plumbing because of the metal’s low melting point and durability.  However, lead exposure can cause developmental problems, cardiovascular issues, and organ damage.  The federal government banned new lead pipes in 1986, but millions of lead service lines remain in service to this day. Chicago has the highest number […]
