That’s sort of like asking, “What happened to the tooth fairy?”
What is really interesting at the moment is what is happening to our oceans. They are the Earth’s great heat stores.
According to research conducted by Professor Don Easterbrook from Western Washington University last November, the oceans and global temperatures are correlated.
The oceans, he says, have a cycle in which they warm and cool cyclically. The most important one is the Pacific decadal oscillation (PDO).
For much of the 1980s and 1990s, it was in a positive cycle, that means warmer than average. And observations have revealed that global temperatures were warm too.
But in the last few years it has been losing its warmth and has recently started to cool down.
These cycles in the past have lasted for nearly 30 years.
So could global temperatures follow? The global cooling from 1945 to 1977 coincided with one of these cold Pacific cycles.
Professor Easterbrook says: “The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling.”
Pacific decadal oscillation. Yeah, baby.
