The difference between tropical east and west Pacific sea-surface temperatures affects local and global climate, and most climate models suggest a weaker future gradient despite a recent observed increase. Research now suggests the recent trends are due to a transient delay in east Pacific warming driven by cold water upwelling and aerosols.

The tropical Pacific east–west temperature gradient intensified recently, but climate models do not reproduce this, and they also predict future weakening. This discrepancy is attributed to a competition between long-term weakening and transient strengthening from aerosols and ocean equatorial upwelling.
In the wake of the Great Recession, natural gas seemed like a viable foundation for economic recovery in Pennsylvania and the greater Appalachia region, which has abundant natural gas reserves.
Humans aren’t the only species that navigate by starlight. Animals from birds to dung beetles may do it, too — and might become disoriented as our city lights drown out the heavens.
