It came as no surprise that 2024 ended up as the warmest year on records. It was the hottest year since record keeping began in 1880. The global average temperature was 1.28 degrees Celsius (or 2.3 degrees Fahrenheit) above the 20th-century baseline period of 1951-1980. It was actually 1.47 degrees above the 1850-1900 average. The […]…

Empire Wind 1, the first offshore wind project that will connect to the New York City grid, has received the financing needed to move forward. Equinor, the Norwegian state-owned multinational energy company developing the project, closed on a more than $3 billion financing package. The wind farm will span 80,000 acres in an area 15-30 […]…

Applying salt to roadways lowers the freezing point of water and prevents slippery surfaces, which makes it safer for people to drive in wintry conditions. In the U.S., more than 22 million tons of road salt is spread every year. But road salt harms infrastructure and the environment. In fact, road salt damages cars and […]…

Flow batteries are rechargeable batteries in which liquid electrolytes flow through one or more chemical cells from one or more tanks. The electrolytes are redox pairs, that is, chemical compounds that can reversibly undergo reduction and oxidation reactions. The most common redox electrolytes include elements like vanadium, chromium, iron, zinc, a…

January saw some major bouts of subfreezing temperatures across much of North America and significant snowfall in places like Pensacola, Florida and New Orleans. This spate of frigid weather undoubtedly prompted many people to question whether global warming is really happening. But such cold spells quite likely are not happening in spite of global…

A decade ago, Ecuador began a major transition to using hydroelectric power. Like in many other South American countries, the presence of abundant rivers could supply large amounts of energy and drive economic expansion and lead to a new era of prosperity. This ambitious plan has run into the impacts of climate change. An extraordinary […]…

The Earth is a pretty big place, and it is easy to think that humans and their activities occupy very little of it. But the impact of human activities on our planet continues to grow. Recent satellite images from NASA’s Earth Observatory show the staggering extent of the human footprint on Earth. Agriculture is a […]…

Last year saw some major trends in the global energy sector. Perhaps the most dramatic was the shift to renewable power, which continued to outpace the projections of both financial analysts and industry experts. 2024 saw new highs in renewable installation, largely due to China, which accounted for more than half of all the solar […]…

According to a new study by researchers at the University of California, Davis and Stanford University, construction materials used in buildings have the potential to lock away billions of tons of carbon dioxide. The study, published in Science, shows that storing CO2 in buildings could be a major contributor to efforts to reduce greenhouse gas […]…

According to the U.S. Department of Agriculture, as much as 40% of the food supply in the United States is wasted. In fact, Americans generate more food waste than all but two countries. To address this problem, the federal government announced a goal nearly a decade ago to cut food waste in half by 2030 […]…

The changing climate is creating challenges for some of the most productive apple growing regions in America. A study by Washington State University analyzed over 40 years of climate conditions that impact the growth cycle of apple trees. Many growing areas face increased climate risk, but the top three apple-producing counties are among the most […

Hydroclimate whiplash is a term that describes rapid swings between intensely wet and dangerously dry weather. Global weather records show that the occurrence of hydroclimate whiplash has increased by 31% or as much as 66% since the mid-20th century. California’s experience is a prime example of this phenomenon. After years of severe drought, dozen…

A decade ago, the ability of utilities to store large amounts of electricity in batteries was basically nonexistent. In the past several years, growth in battery storage systems has exploded. As of the end of November, the US had about 24 gigawatt-hours of storage capacity in place. This is 71% more than just a year […]…

Advances in genomics have created the possibility of bringing back extinct species from the past by making use of recovered DNA from preserved specimens. Companies attempting to “de-extinct” iconic species have received hundreds of millions of dollars from venture capitalists. These companies are trying to bring back iconic species that include ivo…

For many years, scientists have warned that the Great Salt Lake in Utah is headed toward a catastrophic decline. While the size of the Great Salt Lake fluctuates naturally with seasonal and long-term weather patterns, the lake has been experiencing significant and steady declines for decades. In fact, the Great Salt Lake has lost more […]…

The Cambridge Energy Storage Project in Cambridge, Minnesota will be the first commercial deployment of iron-air battery technology. Developed by startup company Form Energy, the battery system will provide 1.5 MW and 150 MWh of multi-day energy storage. Iron-air batteries are based on the principle of reversible rusting. When discharging, the batt…

The most abundant protein on the planet is an enzyme called ribulose-1,5-bisphosphate carboxylase/oxygenase, better known as RuBisCO. Its critical role in photosynthesis makes life as we know it on earth possible. What it does is convert carbon dioxide from the atmosphere into the organic matter contained in plants. Getting plants to take up more c…

The interests of billionaires seldom seem to coincide with our own. In fact, they often seem to be quite the opposite. But there are a number of billionaires who are trying to help the world combat climate change. Yes, they want to make money doing it, but doing it is nevertheless in everyone’s interest. A […]…

The Paris Climate Agreement is a global treaty adopted in 2015 to combat climate change by limiting global warming to well below 2°C above pre-industrial levels, while striving to keep it below 1.5°C. But according to recent research, the planet is quickly approaching these critical thresholds. An international research team led by scientists from …

Temperatures in cities are rising around the world and urban heat stress is already a major problem. Extensive surfaces of man-made materials absorb the sun’s energy, and lead to temperatures well above those in the surrounding countryside. This is known as the urban heat island effect, and it can lead to greater energy use, higher […]…
