Global warming is influencing where tropical cyclones rage

While the global average number of tropical cyclones each year hasn’t budged from 86 over the last 4 decades, climate change has been influencing the locations of these deadly storms.

Why is Earth’s magnetic north pole drifting so rapidly?

The location of Earth’s north magnetic pole appears to be controlled from deep within Earth by 2 competing blobs in the magnetic field. One is under Canada, and the other is under Siberia. “The Siberian blob is winning,” according to scientists.
