Atlantic Multidecadal Oscillation (AMO)
- Next decade 'may see no warming'

La Nina conditions have brought unseasonably cold weather to Europe
The Earth's temperature may stay roughly the same for a decade, as natural
climate cycles enter a cooling phase, scientists have predicted.
A new computer model developed by German researchers, reported in the
journal Nature, suggests the cooling will counter greenhouse warming.
However, temperatures will again be rising quickly by about 2020, they say.
Other climate scientists have welcomed the research, saying it may help
societies plan better for the future.
The key to the new prediction is the natural cycle of ocean temperatures
called the Atlantic Multidecadal Oscillation (AMO), which is closely related
to the warm currents that bring heat from the tropics to the shores of
The cause of the oscillation is not well understood, but the cycle appears
to come round about every 60 to 70 years.
