A look at our changing environment.
Europe has 37 gigawatts of offshore wind capacity. China is catching up rapidly. Across the globe, offshore wind is an increasingly important source of clean, renewable power. The United States had previously set ambitious goals to join the international effort. But in the aftermath of the 2024 election, offshore wind in the US is basically […]
Hydrogen is an ideal climate-friendly fuel because it doesn't release carbon dioxide when it is used. But most hydrogen is produced in ways that result in significant carbon emissions. Thus, the search for green hydrogen goes on. Last year, engineers at MIT developed a new process for making hydrogen that significantly reduces the carbon footprint […]
As climate change accelerates, rising sea levels are putting coastal communities at greater risk of flooding and storm surge. Driven by melting glaciers and warming oceans, global sea levels are rising at an increasing rate. For low-lying cities like New Orleans, even small increases can have serious consequences. And that risk is compounded by another […]
Ocean shipping is a significant contributor to global carbon emissions, accounting for about 3% of the total. It is a key part of international trade, moving goods like electronics, automobiles, and oil. It relies on fossil fuels, and, without significant changes, shipping's emissions could more than double by 2050. Ocean shipping is one of the […]
Honeybees are a critical resource for American agriculture. The western honeybee, Apis mellifera, pollinates more than 130 types of nuts, fruits, and vegetables, adding up to $15 billion worth of crops every year. Honeybee health has been harmed by a combination of factors: weather extremes, habitat loss, pesticides, and disease. One of the biggest problems […]
Hotter and drier conditions driven by climate change are leading to an increasing number of wildfires in North America and around the world. The damage wildfires cause – to forests, homes, and communities – is well-known. But long after the flames are gone, the effects can linger, especially in rivers and streams, where water quality […]
An important part of the 2015 Paris Climate Agreement is reducing the use of coal to produce electricity. Coal is the dirtiest fuel in common use and not burning it is a way to greatly reduce emissions. Ten years later, coal consumption around the world has decreased dramatically. The most convenient alternative to coal is […]
TfL – Transport for London – the operator of the transportation system in Britain's capital city, has signed a deal with EDF Renewables to purchase electricity from a huge solar array to be erected next year in Essex. TfL has the goal of powering 100% of its entire transit system – including its sprawling underground […]
Tropical forests are dying at an alarming rate, and not just from deforestation. Even intact forests are losing trees, threatening biodiversity, carbon storage, and the global climate. While drought and rising temperatures are often blamed, new research points to a surprising culprit: thunderstorms. These intense, short-lived convective storms, common in the tropics, are increasing due […]
June and July have both seen multiple days with temperatures in the 90s in London, England. This is almost unheard of, but according to British scientists, record-breaking extreme weather has become the new norm in the UK. Weather records show that the UK's climate is different now compared with just a few decades ago. The […]
The Trump Administration is outwardly hostile to renewable energy, especially solar and wind power. Federal support for these energy sources that are by far the most rapidly growing energy sources across the globe is being gutted while fossil fuels are being propped up. There is also renewed enthusiasm for nuclear power and, somewhat surprisingly, geothermal […]
It is unfortunately well-known that microplastics are pretty much everywhere on Earth. They are also increasingly found in living things like birds and dolphins as well as in human brains and placentas. The oceans are polluted with plastic, and for the first time, there is now an estimate for the volume of nanoplastics – which […]
In June, solar power was the largest source of electricity in the European Union for the first time. Solar supplied a record 22% of the power for the 27-country bloc. At least 13 of the countries produced new monthly highs for solar power in June. The Netherlands got more than 40% of its electricity from […]
Tree plantings have become a go-to climate solution for governments and conservation groups due to the carbon-storing potential of trees. While planting new trees on open farmland would help capture additional carbon, a new study led by scientists from Yale School of the Environment suggests a powerful alternative: forest-based agroforestry. Instead of clearing land for […]
This summer has already seen unprecedented heat in many places. It started with a record-breaking heat dome in June in the United States. Alaska had its first-ever heat advisory that month. Europe has seen triple-digit temperatures in cities like Paris, Madrid, and Rome and even in places like Austria, Sarjevo, Bulgaria, Croatia, and Serbia. On […]
Cement pretty much holds the modern world together. The amount of cement required to create our infrastructure is almost incomprehensible. By weight, humanity consumes more cement than food, about 3 pounds per person per day. The cement industry produces around eight percent of global CO2 emissions, which is more than the aviation industry. So, if […]
Tens of thousands of raccoons live in Kassel, a city of 200,000 people in central Germany known for its art scene. Overall, there are an estimated 1.5 million raccoons in Germany. The omnivorous mammals are native to North America, but they were brought to Germany in the 1930s for fur farming. Fur farming ultimately ceased […]
An estimated 30 million tons of wood waste from construction and demolition in the U.S. ends up in landfills each year. A growing number of cities have launched initiatives to reuse the wood instead. It is a strategy to reduce carbon emissions, cut waste, and shift towards a circular economy. For a long time, salvaged […]
Poultry farms are a significant source of air and water pollution. In the US, they are the largest source of ammonia emissions, followed by dairy and non-dairy cattle farms. Poultry farms emit over two million tons of ammonia per year. Ammonia is not directly produced or excreted by the birds but is a common by-product […]
Increasing reliance on digital technologies in general and artificial intelligence in particular are dramatically increasing the energy consumption of data centers. Data centers consume far more energy per square foot than other commercial buildings. By the year 2030, data center energy consumption in the US is projected to reach 9% of the country's electricity generation. […]
Sea surface temperatures broke records in 2024 and a quarter of the world's oceans are experiencing temperatures that qualify as a marine heatwave. A marine heatwave is a prolonged period during which ocean temperatures are significantly warmer than average for that specific location and time of year. Unusual heatwaves have occurred in all the major […]
Getting people to recycle isn't always easy. The bottled beverages we buy at the supermarket often require a small deposit that we can get back by recycling the bottle, but often, we just don't. Researchers from the University of British Columbia tested the idea of giving people returning bottles a small chance of winning a […]
Ultra-pure water is essential for multiple industries, for example semiconductors, batteries, and pharmaceuticals, as well as food and beverage companies. Such water is produced by various processes including desalination plants that use reverse osmosis. The byproduct of the processing is industrial brine: salty wastewater. The brine produced by desalination is generally dumped into the ocean […]
Planting lots of trees is one of many strategies being pursued to combat climate change. Forests absorb carbon dioxide, provide shade, and help regulate temperatures. They also support biodiversity and improve air and water quality. According to a new study by researchers from the University of California – Riverside, restoring forests to their pre-industrial extent […]
The idea of using hydrogen as a fuel or an energy source has been around for a long time. Hydrogen is the most common element in the universe, but most of it is locked up in various chemical compounds, such as water. Hydrogen is a clean fuel; burning it or using it to generate electricity […]
Worldwide, people are producing more food than ever, but most of that production is concentrated into only a handful of places. For example, fully one third of the world's wheat and barley exports come from Ukraine and Russia. Across the globe, several major crop-growing regions, including some in the United States, are heading towards sharp […]
The majority of us spend about 80% of our time indoors. The quality of the air that we breathe depends on the age and type of building we occupy along with any sources of indoor pollution that may exist and, ultimately, the quality of the air outdoors. The HVAC used to heat, ventilate, and cool […]
More than 30% of the world's food is lost after it has been harvested. That's enough to feed more than a billion people. Much of that loss is fruits and vegetables that go bad before they can be eaten. Refrigeration is the most common way to preserve foods, but the energy and infrastructure required is […]
Nuclear power has been around since the 1950s, but it has fallen out of favor in recent decades, in part due to a couple of traumatic disasters at nuclear power plants. In fact, only two new nuclear power plants have been built in the US in the past 30 years, and they took a very […]
As global temperatures continue to rise and ecosystems shift, animals are left with limited options. They must either adjust to the changing conditions in their habitats or relocate to cooler environments. For many species, neither choice is easy – or sometimes even possible. Ecologists had long assumed birds were among the most adaptable species in […]
Sea Urchins are real troublemakers. On the West Coast, the sea urchin population exploded when the sunflower sea stars that eat them were decimated by a wasting disease. Urchins devour kelp and they ate up 96% of the region's kelp forests. Kelp forests serve as shelter and food for a vast array of marine life […]
Air pollution is a problem for most of the world's cities. Many cities in India and China continue to face major public health crises due to their polluted air. American cities also don't escape from polluted air. Californian cities still struggle with smog despite decades of effort to reduce it. But one major city that […]
The world lost a record amount of forests last year. The biggest factor for the unprecedented losses were wildfires that raged around the world. According to the annual update by the University of Maryland and the World Resources Institute, pristine rainforests alone lost 17 million acres, which was nearly twice as much as in the […]
Climate science is not popular with the current administration. Phrases like “climate crisis”, “clean energy”, and “climate science” itself are prohibited from websites, reports, regulations, and other communications by government employees and federal funding recipients. Once again, the United States is turning away from climate mitigation efforts and will have a drastically reduced ability to […]
Researchers estimate that hundreds of millions of birds die hitting buildings every year in the United States. Striking buildings is believed to be one of the major factors behind the nearly 30% decline in North American bird populations since 1970. Chicago is one of the most dangerous cities for migrating birds based on its location […]
As the world struggles to implement technologies and find the political will to reduce carbon emissions, there are also ongoing efforts to find ways to capture carbon from emitting sources and from the atmosphere itself. After capturing carbon dioxide, there is then the need to safely store it or make use of it. Current methods […]
A substantial amount of corn is grown in this country for the purpose of producing ethanol. The value of doing so is debatable for many reasons. Nevertheless, the majority of the corn crop is grown for food. But along with all that corn, there is corn stover. Stover is the dried stalks, leaves, and other […]
Globally, coastal areas are being squeezed between rising seas on one side and human development on the other. The average distance from the high waterline to the first built-up area with human structures or paved roads is less than 400 yards around the world. The narrower a coast, the sooner rising sea levels cause problems. […]
Concrete is the most widely used building material on Earth. It has a dangerous and costly flaw: it cracks easily. Cracks in concrete can lead to inconvenient damage or to catastrophic structural failures such as collapses of buildings, bridges, or highways. Concrete is made by mixing crushed stone and sand with powdered clay and limestone […]
A new study by the Columbia University Climate School has found that all of the 28 most populous cities in the United States are sinking to some extent. This phenomenon of subsidence is not just taking place in cities on the coast, where relative sea level is an issue, but also in cities in the […]
Floating photovoltaic systems – known as floatovoltaics – are becoming increasingly popular. These are arrays of solar panels installed over artificial water bodies such as irrigation ponds, wastewater treatment plants, and reservoirs. These projects maximize the space for producing clean energy while not taking up natural lands. Wherever there are bodies of water, there are […]
Carbon dioxide and nitrogen oxides are two of the most problematic human-generated air pollutants that negatively impact air quality, the climate, and human health. Satellites are an important tool for monitoring emissions of these pollutants, but they have limitations. For the most part, satellites have limited spatial resolution, meaning that they can't reliably narrow down […]
Vertical farming has been increasingly used for leafy greens like lettuce and kale, as well as for herbs and a few fruits like strawberries and tomatoes. A recent study by the Technical University of Munich has investigated the use of vertical farming for a much broader range of foods. The study looked at the positive […]
After hiding underground for the last 17 years, billions of cicadas are taking to the skies this summer. This batch of insects, known as Brood XIV, will cover more of the U.S. than any other 17-year brood. New York and at least 13 other states – Georgia, Kentucky, Maryland, Massachusetts, New Jersey, North Carolina, Ohio, […]
In April, the Trump Administration issued a stop order for the Empire Wind offshore wind project in New York, pushing the $5 billion project to the brink of collapse. The project is being built by the giant Norwegian energy company Equinor. When completed, the wind farm is expected to deliver enough electricity to power 500,000 […]
Researchers at the University of Waterloo in Canada have developed a method for restoring peatlands at tens of thousands of oil and gas exploration sites in Western Canada. A well pad is a prepared area used for drilling oil or gas wells, encompassing the site where drilling equipment, wellheads, and related facilities are located. Preparing […]
As global temperatures rise due to increased greenhouse gas emissions, communities around the world face more frequent and intense heatwaves, droughts, and extreme weather events. These growing climate pressures not only strain infrastructure and natural resources, but also play a critical role in shaping where people live. Recent projections from the First Street Foundation, which […]
Atoll islands are made from sediment produced by corals, clams, snails, and varieties of algae that secrete carbonate. Under the right conditions, over time, fragments of coral skeletons, shells, and other sediments made by marine life are piled up by waves. Eventually, islands are formed – some large and some small. Atoll islands are home […]
Worldwide investment in renewable energy topped $2 trillion in 2024. For Climate Solutions Week, we wanted to highlight some amazing projects around the world that showcase innovative technology, ambitious scale, and the commitment to a cleaner and sustainable future. In Morocco, the Noor Solar Power Station is a huge concentrated solar power facility that generates […]
Nature is often seen as a victim of climate change, but it's also one of the most powerful tools we have to fight it. Natural ecosystems, such as forests, wetlands, grasslands, oceans, and soils, absorb and store massive amounts of carbon dioxide. These ecosystems not only help reduce the concentration of greenhouse gases in the […]
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, […]
