Shrinking Arctic ice and the wicked backlash on our weather - Capital Weather Gang - The Washington Post
Heat waves. Drought. Flooding. Cold spells. Wildfires. The climate system is changing before our very eyes, and there is no more glaring proof than the record-shattering loss of Arctic sea ice this summer.
...It now appears, however, that a gradual warming may not be the primary concern, as the gases may also fuel extreme weather around the world.
The weather we experience at mid-latitudes is largely dictated by these waves in the jet stream. The slower the waves move, the longer the weather associated with them will persist. Essentially, “hot,” “dry,” “cold,” and “rainy” are all terms to describe very normal weather conditions. It’s only when those conditions persist in one area for too long that they are dubbed with the names of their extreme alter egos: heat waves, drought, cold spells, and floods. And these kinds of extreme events are precisely what we’ve seen more of in recent years.
Global warming now has a face and a fingerprint that directly touch each of our lives. Rather than just a gradual increase in temperature, we can recognize its influence in a shift toward more extreme weather events. A warmer atmosphere also means a moister atmosphere, so any given storm will have more moisture and energy to work with, increasing the chances of flooding or heavy snows.
