Ozone Pollution: An Insidious and Growing Threat to Biodiversity

Yale E360

OCTOBER 7, 2021

Ground-level ozone has long been known to pose a threat to human health. Now, scientists are increasingly understanding how this pollutant damages plants and trees, setting off a cascade of impacts that harms everything from soil microbes, to insects, to wildlife. Read more on E360 ?.

What Exactly is Ozone? The Good, the Bad & the Ugly

DECEMBER 7, 2021

Our ozone layer serves as a lifesaving UV barrier for planet earth, functioning to absorb most of the sun’s ultraviolet radiation. At the same time, ground-level ozone pollution is extremely harmful to human health. As the complexity of ozone pollution is often misunderstood, let's take a closer look at this particular pollutant.

CMIP6: Not-so-sudden stratospheric cooling

MAY 21, 2023

The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. That means the greenhouse substances are basically just CO2 and ozone, and they absorb in quite different parts of the spectrum. But why is the stratosphere increasingly chill?
