Arctic salt clouds are reducting the impact of Global Climate Change on the Arctic region

Prior posts have noted both the various impacts of Global Climate Change ("GCC") on various aspects of the Earth and its atmospheric systems, as well as the failure of many/most models to include such impacts within their parameters. For example, a recent post noted that the solar cycle has...

What is the source of the oceans' production of N2O, a potent GHG?

The oceans emit an estimated 30% of the nitrous oxide (N2O) entering the atmosphere. Nitrous oxide gives rise to NO (nitric oxide) when it reacts with oxygen atoms, and this NO in turn reacts with ozone. As a result, N2O is the main naturally occurring "regulator" of stratopheric ozone. N2O...
