One train-mounted air quality sensor can cover the same area as 30 stationary sensors.

Civilization may need to “forget the flame” to reduce CO2 emissions.

Use of forests to offset carbon emissions requires an understanding of the risks

Using data from NASA’s Orbiting Carbon Observatory-2, researchers found connections between the population density of cities and how much carbon dioxide they produce per person.

Could the rising levels of carbon dioxide actually be good for plants?

Researchers use fluorescence as a proxy to track photosynthesis in evergreen forests.
