Climate change is already affecting the yields of major staple crops around the world, and researchers warn that the impacts will become more severe over time. Rising temperatures, shifting rainfall patterns, and more frequent extreme weather events are disrupting growing seasons and reducing agricultural productivity. Addressing these growing threats requires rethinking how we grow, distribute, […]

The Human Genome Project is one of the greatest scientific feats in history.  It was launched in 1990 and completed in 2003.  The international group of researchers wanted to comprehensively study all of the DNA – the genome – from a select set of organisms, foremost of which being that of human beings.  The results […]

Over the first several months of this year, hundreds of sea lions, dolphins, and seabirds have fallen ill or died after eating sardines or anchovies that had been feeding on an algal bloom along the California coast since winter.  The biotoxin in the algae accumulates in the feeder fish. Two cases of whales dying from […]

New studies have found that devoting a small percentage of U.S. farmland to producing solar power would benefit both the country’s energy system and its farmers. Currently, about 46,000 square miles of farmland – about the area of Pennsylvania – is being used to grow corn to make ethanol.  One study looked at the impact […]

Beginning in 2013, a mysterious disease associated with a marine heatwave decimated the population of sunflower sea stars.  Those huge, colorful 24-armed starfish thrived along the Pacific Coast between Alaska and Baja California.  But in fairly short order, nearly six billion of the creatures perished, amounting to 94% of the global population.  California lost 99% […]

According to the American Lung Association’s annual State of the Air report, at least 156 million Americans – 46% of the population – live with unsafe levels of ozone, particulate pollution, or both. The report analyzed ozone and particulate pollution levels between 2021 and 2023, during which the worst wildfire season on record took place […]

Slowing human-caused climate change requires decisive action.  But according to psychologists, the gradual rise in global temperatures can lead to climate apathy, especially among those who don’t face frequent climate disasters. Climate apathy is a general indifference or lack of emotional or behavioral response to climate change and environmental issues.  People experiencing climate apathy may […]

The world is a big place but even things that are far away can have serious local consequences.  The effects of distant Canadian wildfires on air quality in Florida is a good example. Europe is increasingly becoming reliant on solar energy to meet its targets for climate change mitigation and energy security.   According to new […]

Feeding a global population projected to reach nearly 10 billion by mid-century is a massive challenge.  Wheat provides a fifth of the calories in the global human diet and is a significant source of protein, minerals, vitamins, and fiber.  Finding ways to increase the yield of wheat crops has great value.  However, wheat has complex […]

Urban areas can have a variety of green spaces:  gardens, parks, and roadside and median plantings.  It turns out that these spaces can serve as pollinator refuges. A study by researchers at the University of British Columbia found that reducing lawn mowing and creating pollinator meadows – essentially parks for bugs – significantly boosts pollinator […]
