Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The situation is further complicated by uncertainty over the amount of methane that leaks from natural gas operations. Methane is an especially potent greenhouse gas. degree Celsius).

NOAA’s updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend. It also includes several chemicals known to deplete Earth’s protective ozone layer, which are also active as greenhouse gases.

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,
