Linsley said the new results were «exciting,» suggesting that the «poorly understood, rapid rise» in surface temperature from 1910 to 1940 was, in part, «related to changes in trade wind strength and heat release from the upper water column» of the Pacific Ocean.

Interestingly, those same winds are thought to be part of the mechanism burying heat in the Pacific Ocean, leading to the slower pace of rising temperatures at the planet's surface in recent decades.

These rising atmospheric greenhouse gas concentrations have led to an increase in global average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

Hotter air on the Earth's surface leads to higher ocean temperatures, which causes ocean expansion and sea level rise;

Increased ocean temperatures also make the waters more stratified — preventing nutrient - rich water from below from rising to the surface and oxygen - rich water from reaching the middle layers.

Thousands of studies conducted by researchers around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; diminishing snow cover; shrinking sea ice; rising sea levels; ocean acidification; and increasing atmospheric water vapor.

There are also concerns that oceans, which currently absorb more than 90 percent of the extra heat being trapped by human greenhouse gas emissions, could eventually release some of that back to the surface, speeding up the surface temperature rise.

At that point in geological history, global surface temperatures were rising naturally with spurts of rapid regional warming in areas like the North Atlantic Ocean.

But then the effective heat capacity, the surface temperature, depends on the rate of mixing of the ocean water and I have presented evidence from a number of different ways that models tend to be too diffusive because of numerical reasons and coarse resolution and wave parameter rise, motions in the ocean.

El Niño is a natural phenomenon occuring every five years or so that causes sea surface temperatures to rise in the equatorial Pacific Ocean.

The graph below shows the strong statistical relationship between annual CO2 rise and the strength of El Niño and La Niña, as quantified by sea surface temperatures in the tropical east Pacific ocean.

As the deep ocean keeps surface temperatures from rising, the equilibrium would still be unattained.

Scientists are currently interested in why temperatures at the surface of the ocean have been rising slower than in previous decades, even though we're emitting greenhouse gases faster than ever.

Burt Armstrong @ 16, you are very much on the right track, but think more in terms of accumulating ocean heat content and rising sea surface temperatures.

After all, if average surface temperature is 15 C, wouldn't you expect land and ocean below the surface to equilibrate at roughly that temperature (with a slightly rising gradient to account for the flow of Earth's internal heat)?

If you believe unforced variation is the cause, please explain why both the oceans and surface temperatures are rising.

These parameters include global mean surface temperature, sea - level rise, ocean and ice sheet dynamics, ocean acidification, and extreme climatic events.

The significant difference between the observed decrease of the CO2 sink estimated by the inversion (0.03 PgC / y per decade) and the expected increase due solely to rising atmospheric CO2 -LRB--0.05 PgC / y per decade) indicates that there has been a relative weakening of the Southern Ocean CO2 sink (0.08 PgC / y per decade) due to changes in other atmospheric forcing (winds, surface air temperature, and water fluxes).

But if something causes heat to be transferred from the ocean surface into its deeps more rapidly than usual, ocean surface temperatures could rise more slowly, not rise at all, or even fall despite the increased backradiation.

The problem is that for most purposes (fluxes of heat into the oceans, and hence ocean warming and hence sea level rise; or biosphere responses) what you care about * is * the surface temperature.

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

Paul S (# 1)-- Since the Planck Response dominates over positive feedback responses to temperature, wouldn't a La Nina - like failure of surface temperature to rise lead to an increase rather than a reduction in energy accumulation compared with accumulation during a surface warming — presumably a small increase, so that the observed rise in ocean heat content would still be substantial?

Gavin, I agree completely with the standard picture that you describe, but I don't agree with the claim that ``... as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming».

However their predictions are about much more than just the average near - surface air temperature, they are mainly focused on how heat mixes into the ocean and how that affects the rise in surface temperature as CO2 is doubled over 100 years.

«Firstly, as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming»

Rising ocean temperatures are contributing to the risk, the report said, noting that the National Climatic Data Center reported that in June the world's ocean surface temperature was the warmest on record.

So, although each molecule of CO2 that escapes from the oceans will, on average, be back in the ocean again in five years time, if the sea surface temperature rises the increase in the atmospheric CO2 will remain.
