This can be assisted by cutting emissions that have a shorter atmospheric residence time вІ methane, halocarbons and nitric oxide. These gases are reactive with ozone and water vapor, producing photochemical smog.

residence timeвІ means we need to reduce these emissions by about 80%.

A new National Oceanic and Atmospheric Administration study suggests cutting emissions of the other greenhouse gases should slow down climate change.

Most of the discussion about slowing the impact of climate change has focussed on reducing carbon dioxide emissions. But carbon dioxide isnвІ t the only greenhouse gas. Methane, halocarbons and nitric oxide are also important contributors to climate change. Are we taking the right steps to reduce these emissions?

COв has the longest residence time, but reducing other GHGs can help us achieve our targets.
