The New York Times published this article last week about how the warming temperature trend across the globe is changing what El Nino looks like. We know that El Nino and La Nina have been natural parts of the atmosphere-ocean climate pattern on Earth for thousands of years and likely much longer. But as the atmosphere and ocean warm up due to greenhouse gases, the way that El Nino and La Nina behave are changing, according to the article. This means it will be harder to predict the climate in the future than it was in the past since the baseline climate is no longer stable. This is especially bad for the Southeast, since a lot of our climate variability comes from the ENSO cycle. The article has some useful diagrams that show how El Nino affects different parts of the world as well as describing how the climate patterns might be different than they were in the past.
