The Solar Wind may be changing the surface temperature of the North Atlantic

Could it be the missing key? The solar wind blasts charged particles, electrons, stuff, towards Earth at 500 km a second  — that’s one to two million miles per hour. It speeds up, slows down and shifts in direction as it travels past the Earth and has its own magnetic field. The wind speed varies from 300 km per second up to 800 and the impact on Earth changes with our magnetic field and our seasons. You might think this kind of monster flow might have some effect on our climate. But modern climate models are 95% certain that none of this matters. Only crazy people would think that a electrons flying past at a million miles per hour could “do something” to our stratosphere, or ozone, or cloud cover.

Curiously, a recent study shows that when the solar wind is fastest, the North Atlantic is coldest on the surface. The NAO (North Atlantic Oscillation) appears to correlate. The effect is strongest in the northern winter months. Notably the modern expert climate models fail to predict any of the cycles within our major ocean basins. How immature is our understanding of space weather?

Could changes in the solar wind be [...]
