When the mode shifts south, the ocean heat uptake will reduce and temperature will reduce because there is
less land amplification.
Not exact matches
I am fairly confident the report will not mention the Pacific Centennial Oscillation, LIA recovery, NH
land amplification, the stratospheric warming event cycles, the
less publicized post 2009 proxy reconstructions, which all combined can barely push the «main cause» limit, because with the playing field shifted completely away from the meat of the debate CO2 forcing.
Less Arctic sea ice, more Antarctic sea ice, more northerly ITCZ, warmer NH warmer
land,
land amplification.
Combining the latitude and
land - only status of the CONUS, the
amplification factor may very well be
less than 1, but a range of values significantly lower than the 1.1 to 1.4 range used in the Watts paper would be reasonable.
The MWP is better explained by the Arctic
Amplification effect whereas northern hemisphere warming is amplified due to faster thermal response to climate forcing due to greater
land mass and
less ocean mass; compared to the southern hemisphere which is largely water (which has a slower thermal inertial response to climate forcings).
