A warmer global average temperature does not necessarily mean every region of the world will get hotter, as regional climate variability produces different effects in different parts of the world, he added. (chimalaya.org)
They collect ice cores in many locations around Earth to study regional climate variability and compare and differentiate that variability from global climate signals. (giss.nasa.gov)
This implies that overall regional climate variability in some places can be usefully constrained on the basis of satellite data alone. (aer.com)
