Agricultural water scarcity is expected to increase in more than 80% of the world's croplands by 2050, according to a new study in the AGU journal Earth's Future.

WASHINGTON Glacial melting due to global warming is likely the cause of a shift in the movement of the poles that occurred in the 1990s.
The locations of the North and South poles aren t static, unchanging spots on our planet. The axis Earth spins around or more specifically the surface that invisible line emerges from is always moving due to processes scientists don t completely understand. The way water is distributed on Earth s surface is one factor that drives the drift.
