Geohacking: Could “green sand” beaches help us fight climate change?
On a beach in the Caribbean, a nonprofit called Project Vesta will soon begin testing a radical new way to fight climate change that involves spreading ground-up olivine—a cheap green mineral—over the sand, where ocean waves will break down the mineral, which in turn will pull CO2 from the Read More...
Could a trash-to-hydrogen plant realize the dream of green hydrogen fuel?
Hydrogen fuel has seemingly fallen off the radar considering all the hype that surrounded this potentially sustainable fuel source in past years. Other than a blatant lack of infrastructure, a big problem with hydrogen fuel is that we haven’t figured out a way to produce hydrogen fuel in a clean, Read More...
Training AI is carbon-intensive. MIT researchers are changing that
The different ways artificial intelligence (AI) can be used to improve our lives is vast, but one thing we often overlook is the environmental cost that comes with AI. After all, running a training model to improve AI requires a whole lot of energy. For that reason, researchers at Massachusetts Read More...
COVID-19’s reduced pollution is providing climate data for the future
If you think some of the world’s top climate scientists are taking a break during COVID-19’s record drop in air pollution, it’s actually quite the opposite. Xinrong Ren, a senior research scientist at the University of Maryland’s Department of Atmospheric and Oceanic Sciences (NOAA), has Read More...
Intel aims to be waste-free and use only clean energy by 2030
While it can almost feel natural to get skeptical when big companies make sustainability pledges, it’s important to remember the big impact these companies have at the end of the day. With that in mind, tech giant Intel has unveiled its environmental goals for 2030 this week, committing to cut Read More...
India witnesses drop in carbon emissions for the first time in four decades
India’s rapid growth as a global economic power over the past decades came in tandem with a sharp, consistent rise in the country’s carbon emissions. Now, for the first time in nearly 40 years, CO2 emissions are falling in India. While the coronavirus lockdown plays a role in the decline of Read More...
A supplement for cows that curbs climate change-causing burps is catching on
There’s a farm in England that now markets its milk as “climate-smart”, but what does that really mean? Apparently, Brades Farm, is one the first to begin feeding its cattle a new supplement that shrinks the amount of methane, a potent greenhouse gas, that cows emit when they belch, thus Read More...
EPA proposes first carbon dioxide standards for airline industry
Despite being in low demand, the airline industry could be getting some greener regulations in the near future. For the first time in the history of aviation, the Environmental Protection Agency (EPA) proposed carbon dioxide standards for the airline industry last week. Although the EPA has Read More...
Minnesota scientists are making an experimental forest for a future climate
The landscape of Minnesota is changing as the climate crisis intensifies. Animals and plants that once were only found in the southern part of the state have moved north, suggesting that as the climate changes, Minnesota, by 2100, will start to resemble an environment similar to the one found in Read More...
New study finds world’s oceans suck up twice as much CO2 as we thought
Looks like we’ve completely underestimated the carbon-sucking power of the world’s oceans. Yes, we knew the ocean plays an important role in regulating the amount of carbon dioxide in the atmosphere, but what we didn’t know was that it sucks up twice as much carbon than previously thought.
