For the past several years, our planet has been undergoing a La Niña phenomenon. This is part of ENSO, where we study the movement and interaction of massive, warm and cool, air and water streams around the world, which affects temperatures all over the globe.

There are three phases - La Niña, which gives us cooler than normal temperatures, neutral, and El Niño, which gives us warmer than normal temperatures.

Despite this longer-than-usual La Niña, for the past few years we’ve experienced record-breaking heat across the globe.

Now, after a brief “neutral” phase, Earth is now heading into El Niño phase , which is expected to last through winter.
