Food's role in climate change has emerged as one of the defining challenges of our time. The journey of a steak, fruit or salad from the vast expanses of agricultural lands to the plates on our tables leaves a significant ...
Since the 1985 discovery of a hole in the ozone layer countries have agreed and amended treaties to aid its recovery. The most notable of these is the Montreal protocol on substances that deplete the ozone layer, which is ...
Emissions of nitrous oxide—a greenhouse gas more potent than carbon dioxide or methane—continued unabated between 1980 and 2020, a year when more than 10-million metric tons were released into the atmosphere primarily ...
Imagine being able to contribute to scientific research just by riding a bike: your bicycle automatically collects valuable air quality data from the different neighborhoods you pedal through, creating a mobile network of ...
As the world transitions to greener sources of energy, demand for the metals used in these new technologies is increasing. But how do you grow the mining industry while still holding the line on carbon emissions?
Efforts to achieve net-zero carbon emissions from transportation fuels are increasing demand for oil produced by nonfood crops. These plants use sunlight to power the conversion of atmospheric carbon dioxide into oil, which ...
The formation of water frost is common on Earth, especially in winter when atmospheric water vapor condenses and freezes on the surface. On Mars, the atmosphere is about 100 times less dense than on Earth, but it too contains ...
When soil microbes eat plant matter, the digested food follows one of two pathways. Either the microbe uses the food to build its own body, or it respires its meal as carbon dioxide (CO2) into the atmosphere.
Income inequality and carbon dioxide emissions for high-income nations such as the United States, Denmark and Canada are intrinsically linked—but a new study from Drexel University has taken a deeper look at the connection ...
A surprising yellow haze of sulfur dioxide in the atmosphere of a gas "dwarf" exoplanet about 96 light years away from our own solar system makes the planet a prime target for scientists trying to understand how worlds are ...
