There’s a new greenhouse gas on Earth, and it's the worst one yet.

When we talk about the ability of greenhouse gases (GHGs) to warm the Earth’s climate, we often categorize these substances by their ‘effectiveness’, or the warming potential of one molecule of one compound.  (Explaining why a ‘good’ GHG is actually ‘bad’ for our planet).  We all know that the quantity of carbon dioxide in our atmosphere is concerning (over 400 parts per million), but other GHGs are actually more effective than CO2.  Methane, for instance, is anywhere from 20 to 30 times more effective a GHG than carbon dioxide (though this figure is highly debatable), explaining why release of methane from northern permafrost melt as the result of a warming climate is such a high priority concern.
