24/7 renewables
Renewable energy sources – in particular solar and wind – are growing by leaps and bounds around the world, in great part because the price for them has been plummeting over the years. This has made…
The cooling power of urban trees
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. In urban areas,…
Progress on ocean energy
Ocean energy or marine energy refers to renewable energy obtained from the ocean’s motion (waves, tides, and currents) and thermal properties that are used to generate electricity. It is a largely…
The world is embracing offshore wind
The United States has mostly stopped developing offshore wind, a technology vehemently opposed by the Trump administration. Five ongoing projects have managed to keep going as a result of federal…
Gray whales and climate change
Gray whales undertake one of the longest annual migrations of any mammal on Earth. They spend the summers feeding in the nutrient-rich waters of the Arctic before traveling about 12,000 miles round…
Vegetarian choices have benefits
A new study by Oxford University conducted at six English worksite cafeterias found that replacing just one meat dish with a vegetarian option had multiple benefits with regard to the healthiness of…
Renewable energy in Texas
Texas is a red state. It has voted for the Republican presidential candidate in every election since 1980. And yet, as a result of efforts by several past Republican governors, Texas is a national…
Sea levels are higher
Climate change is raising sea levels. Sea level rise has been tracked for quite a while and its risks to people who live in coastal areas have been the focus of a great deal of attention. But sea…
A boom in used electric cars
Americans who own their cars tend to keep them for a long time – 8 to 12 years. But those who lease their cars often only drive them for two or three years. Many people lease cars for just this…
Trouble from the next El Niño
Projections are that a strong El Niño is on the way. An El Niño is a natural release valve for ocean heat. It starts with shifts of swirling ocean currents and winds over the Pacific. The result is…
A tree that removes microplastics
The moringa tree is a short-lived, fast-growing, drought-resistant tree native to northern India. Its seeds and fruit are valued for their flavor and nutritional value and the tree is known as “the…
Some of the ocean’s most powerful predators are overheating
Mesothermic animals occupy a middle ground between cold-blooded and warm-blooded species. Mesotherms are able to generate and retain some body heat while still relying partly on their environment.…
The largest urban battery facility
Battery storage is reshaping the U.S. electricity grid. There are more than 900 utility-scale battery storage projects across the country that enhance grid reliability, manage peak electricity…
California’s thirsty data centers
Data centers use vast amounts of water primarily for evaporative cooling, spraying it into the air or over coils to cool hot air generated by servers in order to keep the equipment from failing. The…
Offshore wind and whales
President Trump has complained extensively about environmental harms to whales posed by offshore windfarms, saying wind turbines are “driving them crazy” and leading to whale deaths up and down the…
United States grid battery manufacturing boom
Renewable energy in the US is facing serious headwinds under the current administration but one area that is absolutely booming is the manufacturing of battery storage technology for the grid. The…
Bad news for the western snowpack
The western American snowpack is nature’s reservoir, providing 60-70% of the region’s water supply. Winter precipitation is stored there and is released slowly during the spring and summer. The…
China’s coal addiction
China is the biggest installer of renewable energy in the world as well as the largest global manufacturer of renewable energy technology. However, it is also the biggest emitter of greenhouse gases…
Thawing permafrost in the Arctic
Permafrost is frozen ground - a mixture of soil, rock, sand, and ice - that remains at or below 0°C for at least two consecutive years. Permafrost covers about a quarter of the landmass in the…
Global air pollution on the rise
IQAir, a Swiss air monitoring company that posts real-time air quality data aggregated from sensors around the world, has issued its annual report for 2025. The report shows that most of the world’s…
