Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. In addition, they darken ice and snow, reducing their reflectivity and hastening global warming. Source: Shindell et al. Click to enlarge.

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

Geoengineering is defined as the deliberate large-scale intervention in the Earth’s climate system in order to moderate global warming. Geoengineering and its consequences are the price we may have to pay for failure to act on climate change. Unless emissions of carbon dioxide can be greatly reduced—i.e.,

The proposed cause or contribute finding concludes that that the combined emissions of CO 2 , CH 4 , N 2 O, and HFCs from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of these key greenhouse gases and hence to the threat of climate change.
