A look at our changing environment.
In the middle of July, Americans along the East Coast and in the Midwest suffered through a massive heat wave that saw actual temperatures soaring and so-called feels-like temperatures go much higher. The punishing heat had many of us reaching for those plastic water bottles all day long as we tried to keep hydrated. Studies […]
We cut down forests all around the world for a myriad of reasons, including livestock grazing, agricultural production, timber, and urban development. But what if we stopped cutting down forests for these things and additionally grew new forests on vacant lots and any other available parcels of land on earth? What impact could this have […]
Scientists using data from NASA satellites have discovered and documented the largest bloom of seaweed in the world, stretching all the way from West Africa to the Gulf of Mexico. The gigantic macroalgae bloom has been dubbed the Great Atlantic Sargassum Belt. The brown seaweed floats in surface water and in recent years has become […]
According to the International Renewable Energy Agency, there were 11 million people employed in renewable energy worldwide in 2018. This compares with 10.3 million in 2017. So roughly three-quarters of a million new jobs were added last year. As more and more countries manufacture, trade and install renewable energy technologies, renewables jobs continue to reach […]
Ending hunger isn’t a question of producing enough food. Globally, enough food is produced to feed all 7.7 billion people on the planet. But despite this, approximately 1 in 9 people go hungry. Conflict, natural disasters, and extreme poverty are some of the main drivers of global hunger. Climate change is another. The more frequent […]
The Amazon is a source of many mysteries. One that was as troubling as it was mysterious was the large amounts of methane emissions coming from the rainforest that were observed by satellites but that nobody could find on the ground. In total, there were 20 million tons of methane whose origin was unknown. An […]
Monarchs are some of the most well-known butterflies in the U.S. It is well-known that populations of the iconic orange-and-black butterflies have been in a steep decline for the last 20 years. In fact, the Monarch population has declined by 80% over that period. Milkweed, the only plant that Monarchs can lay their eggs on, […]
The Chattanooga Metropolitan Airport in Tennessee has become the first airport in the United States to run entirely on solar power. The small airport operates over 60,000 flights a year and has recently completed work on a 12-acre, 2.64-megawatt solar farm that generates enough clean electricity to account for the airport’s total energy needs. The […]
There have been some blistering heatwaves this summer – in Europe, in the Middle East, and here in the United States. A new report by the Union of Concerned Scientists projects that within the next 20 years, millions of people in the United States could be exposed to dangerous “off-the-charts” heat index conditions of 127 […]
Gillnets are one of the most common types of fishing gear and are used extensively in most places where people fish for food. They operate by suspending a wall of netting in the water column. Unfortunately, they are not selective in the species they catch. Sea turtles are one of the most common bycatch species […]
Human beings are utterly dependent upon energy both for our well-being and for societal development. Our energy use is highly dependent upon climate since so much energy is expended either keeping us warm in winter or cool in summer. As the climate changes, it is important to understand how energy demand is likely to be […]
The latest annual nationwide survey of beekeepers in the US revealed that honeybees are still dying off at an alarming rate. According to the survey, beekeepers across the country lost 40.7% of their honey bee colonies from April 2018 to April 2019. This annual loss represents a slight increase over the average annual loss of […]
Indigo dye is what is used to color denim cloth and blue jeans. Historically, the dye came from a tropical plant most often found on the Indian subcontinent. Eventually, it became economically favorable to synthesize the dye instead and almost all of the 50,000 tons of the dye used annually is synthetic. The processes used […]
Marine litter – particularly plastics – is a global, persistent, and increasing threat to the oceans. Much of it comes from discarded materials on shore that makes their way to the sea but waste from the fishing industry is a also a major contributor to the problem. Commercial fishers are acutely aware of the potential […]
Sahara Desert winds blasted Europe in June, especially during a five-day heatwave that set many records. Between that and weather elsewhere, June was not only one of the hottest ever for that continent, but also for the world as a whole. In Europe, the average temperature was about 5 degrees Fahrenheit above the June average […]
Large companies around the world are facing up to the fact that climate change could substantially affect their bottom lines within the next five years. Shareholders and regulators have been applying pressure to companies to disclose the specific financial impacts they could face as the planet warms and companies are increasingly making those disclosures. A […]
The world’s largest offshore wind farm recently began operations in the North Sea, a notoriously gusty stretch of open water that has become home to multiple large wind farms. The new Hornsea One wind farm is located 75 miles off the east coast of Yorkshire in the United Kingdom. The first 50 turbines are now […]
According to a new study published in the journal Environmental Science & Technology, Americans consume more than 70,000 microplastic particles every year from the food they eat, the water they drink, and the air they breathe. While the health impacts of ingesting these tiny particles are largely unknown, there is the potential for the plastic […]
We mostly think of air pollution as an outdoor problem. The primary culprits are vehicle and factory exhaust as well as occasional wildfire smoke. What we don’t think about is the air quality inside our own homes. Researchers at Washington State University have found that indoor pollution levels can be surprisingly high and that they […]
More and more places are instituting bans on single-use plastic bags. Places like California and Hawaii already have bans in place and New Jersey is considering such a ban. New York’s law will go into effect next March. Supermarkets will no longer provide plastic bags at the checkout line. But the laws have some exceptions, […]
