[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG,
water vapor, exists in equilibrium with
water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the
oceans cover so much of the planet,
water is a large positive feedback; melting snow and ice as the atmosphere
warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar
warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River
where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
Other factors would include: — albedo shifts (both from ice >
water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly
warm, rain fall on ice; — «stuck» weather systems bringing more and more
warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea
water getting under parts of the ice sheets
where the base is below sea level; — melt
water lubricating the ice sheet base; — changes in
ocean currents -LRB-?)
Partly this has to do with changes in
ocean circulation taking
warmer water deeper and partly as the result of the southern hemisphere having less land mass and more
ocean —
where the
ocean has a higher thermal inertia, meaning that it takes longer for those
waters to
warm.
There is also a phenomenon called La Niña («the girl»)-- the extreme opposite of El Niño —

There is so little understanding about how the
ocean parses its response to forcings by 1) suppressing (local convective scale) deep
water formation
where excessive
warming patterns are changed, 2) enhancing (local convective scale) deep
water formation
where the changed excessive
warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep
water formation locations as a result of a) shifted patterns of enhanced
warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced
ocean features to critically altered destinations.

water from the deep
ocean and has possibly played a major role in the specific trends for that period.

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian
Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator,
warm over the bulk of the North Atlantic, strongly
warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold
water from the north whenever the Gulf Stream is running quickly.

ocean (
where changes in heat content are hard to accurately measure), etc..

Some of the
warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by
ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade w
