Thumbnail of volcano eruption   Super-Eruptions, Climate and Human Survival
Explosive volcanic eruptions can cool climate for a short period, but can a super-eruption such as occurred 74 thousand years ago lead to ice sheet formation?

Surface air temperature changes from 1890 to 2000, from iBC-albedo effects.   Particles Multi-Task to Change Climate
Tiny particulate matter in the atmosphere can both warm and cool the climate. Which effect is dominant, and will the balance change as the atmosphere warms due to greenhouse gases?

Close-up of still from video of ozone levels at North Pole   Climate Change Will Make for Uneven Ozone Recovery
New research by NASA suggests the ozone layer of the future is unlikely to look much like the past because greenhouse gases are changing the dynamics of the atmosphere.
