There has been plenty of discussion of El Niño, the periodic weather phenomenon in which prevailing easterly winds in the Pacific Ocean weaken, allowing warm water to move eastward and wreak havoc with the weather in North and South America. The current El Niño is a particularly strong one; some say it may be one of the strongest ever and are calling it the “Godzilla El Niño.”
The city of Holtville in California is sometimes called the “Carrot Capital of the World.” This agricultural community has signed an agreement with Australian company Infratech to build a floating solar power system for its water treatment plant.
Crocodiles are large aquatic reptiles that live throughout the tropics in Asia, Africa, the Americas, and Australia. The first crocodiles appeared approximately 240 million years ago – around the same time as dinosaurs. And while the resilient species did survive the last great extinction, crocodiles might not be climate change-proof after all.
There is much talk these days about energy storage. As more and more wind and solar power enters the electrical grid, there is an increasing need to be able to store excess energy and have it available when the wind isn’t blowing or the sun isn’t shining. Much of the talk centers around battery technology, and having storage batteries distributed throughout the grid is the most versatile and widely applicable way to provide storage.
Climate change is causing the world’s lakes to warm, with repercussions for fisheries and freshwater supplies. So reports an ambitious new study, funded by NASA and the National Science Foundation, and recently published in Geophysical Research Letters.
The forest is playing a symphony. By tapping into environmental monitoring sensors at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire, a tool called WaterViz captures a real-time audio visualization of the forest’s water cycle.
Many people often complain about not having enough time to exercise. But what if exercising for one hour could power your home for twenty-four hours? Would that be enough motivation?
The National Hockey League seems like an unlikely environmental ally. But a sport born on frozen lakes stands to lose a lot in a warming world. NHL Commissioner Gary Bettman is committed to keeping “the air clean and the ponds frozen for future generations.”
The historic, relentless drought in California has caused a number of the state’s farmers to start planting photovoltaic panels instead of crops. Because of the drought, Federal water deliveries to farmers in the Central Valley and elsewhere have been dwindling. As a result of the water shortage, more than 500,000 acres will lie fallow this year.
Beavers are one of nature’s most industrious engineers. Using branches and mud, the intrepid animals create dams that slow moving water. In New York’s Hudson Valley, their constructions are a common sight on streams and in wetlands.
Atlantic cod has been the basis of a major fishing industry in the Gulf of Maine for centuries and is a key species in the local ecosystem. Overfishing decimated the population of cod and in 2010, fisheries managers imposed a series of restrictions on harvesting the fish in order to try to help the species to rebound.
A recent study showed that this year the snowpack in California, which is suffering an ongoing drought as well as long-term warming, reached its lowest point in 500 years. Snowmelt from the Sierra Nevada mountains fills reservoirs that provide a third of all of the drinking water for the state of California, as well as water used to fight fires and generate electricity.
Solar energy has made a difference in the lives of refugees from natural disasters and political unrest as well as people in remote corners of the world who don’t have access to modern technology. There are various solar-powered lamps, chargers, and cookers that have been provided to countless thousands of people around the world.
The Joint Center for Artificial Photosynthesis was established at Caltech and its partner institutions in 2010 with one main goal: to find a cost-effective way to produce fuels using only sunlight, water and carbon dioxide. The natural process of photosynthesis in plants accomplishes exactly the same thing. As a result, such a solar fuel generation system is generally described as an artificial leaf.
It may seem like we are constantly talking about toxic algal blooms – in the ocean, in lakes, and in rivers. That’s because they are occurring with greater frequency and are posing a greater threat than they have in the past.
Globally, there are more than 3,000 mosquito species, with around 150 native to the U.S. To many listeners – a mosquito is a mosquito. But depending on the species that bites you, mosquitoes can be a nuisance or a public health threat.
