Actually, winters are not getting colder. It only feels like it sometimes.
Over the last many years, the world has slowly gotten hotter. This difference in temperature is minusculea fraction of a degree which means that to most of us, things seem normal.
However, it’s a potentially ominous indicator of global warming. It doesn’t take much of an increase in average temperatures to have a devastating effect on humans, crops, plants, and wildlife worldwide.
Not that this warming trend precludes individual locales or regions having unusually cold winters.
You may have heard your local weather guy talk about record-breaking low temperatures, or the worst snowstorm on record in your city, but these isolated events are exceptions to the general trend.
The ten hottest years on record have all occurred within the last two decades.
