One of the predicted effects of climate change is that we should begin to see more climatic extremes. And that is happening....look to the recent floods in Peru. During the first part of January, there was a developed El Nina off the coast. In a little over two months, the Nina disappeared, and an El Nino formed....very warm water. My friend (who is an earth scientist) says he has never observed this before. So we are seeing more extreme oscillations between high and low air temperatures (today it is 85 .... way too warm for early spring in SW New Mexico) and tomorrow it will be 50 with rain. This is happening all across the globe. Here is another example. During the years of the California drought, there was a large body of warm water off the coast of the northwest US. It disappeared last year...and now we have floods in CA and the northwest. Are the two related? Certainly ocean circulation is a big driver of weather. Who knows. Just some observations.
