Why is it as critical to address as carbon dioxide? In the first two decades after its release, methane is 84 times more potent than carbon dioxide. ...

In summer, the warm southern winds blow moist, hot air into the eastern and central US, leading to days of high humidity and sultry conditions. In spring and fall, moving low and high pressure areas pull alternating warm and cold air masses across a given area, leading to a lot of variability in day-to-day weather.
