The Atlantic Meridional Overturning Circulation — the ocean conveyor belt that keeps Northern Europe from freezing — is weakening faster than any IPCC scenario anticipated.

The implications for European winters, Atlantic storm tracks, and global precipitation patterns are substantial and underreported.
