The pandemic, along with other recent trends such as the shift towards clean energy, have placed us at a crossroad: the choices we make today can change the course of global emissions.
Good ventilation can reduce the risk of catching coronavirus. An environmental engineer explains how to know if enough outside air is getting into a room and what to do if ventilation is bad.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That’s always puzzled scientists, but now they think they know what happened.
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.
From Nairobi to Los Angeles, pandemic lockdowns have cleared pollution from the skies. But those blue vistas may be temporary, and shutdowns aren’t slowing climate change.
Bubbly waters are becoming increasingly popular. While these carbonated, sometimes flavored beverages might cause slight harm to teeth, they are far better than soda. They might even be good for you.
Researchers are turning microbes into microscopic construction crews by altering their DNA to make them produce building materials. The work could lead to more sustainable buildings.
