Scientists» measurements, over the last 30 years or so, seem to reflect a steady increase in CO2 emissions, which seem to be causing both a rise in temperature and change in ocean ph toward acidity.

1) It seems to me that the key mechanism for any impact must be the changes that increased arctic ocean temperatures will impose on the atmospheric circulation feature known as the Polar Cell, and via this on the Ferrel cell which sits over the mid latitudes.

And at last they have found a new one: they suggest that the difference in the temperature increase over land and the oceans during the last decades might be due to contaminations of the land temperature record — They call it an anomalous behaviour — ignoring that it corresponds fully to what is physically expected.

There is also a natural variability of the climate system (about a zero reference point) that produces El Nino and La Nina effects arising from changes in ocean circulation patterns that can make the global temperature increase or decrease, over and above the global warming due to CO2.

Nice misconception you have going there but the real argument is that CO2 can lower the temperature gradient of the cool skin layer, which slows the heat loss to the atmosphere and increased levels of greenhouse gases lead to more heat being stored in the oceans over the long - term.

Though hurricanes strenthen when moving over warmer water, this is merely due to the fact that the horizontal temperature gradient of the atmosphere is not as steep, i.e. the temperature differential between the water and the atmosphere increases as the storm hits tropical waters; it is not the ocean temperature per se that drives the hurricane.

However, as the ocean's surface temperature increases over time from the effects of climate change, more and more heat is released into the atmosphere.

During times of warmth, the ocean water levels rise as atmospheric moisture increases but at a rate decelerating when atmospheric temperatures over oceans approach say 33 C.

Similarly, if there is an increase in the difference between land and ocean temperatures, the rising air over land draws in moist air from the ocean and lifts it, leading to monsoons.

In your case, the ice cores must be wrong, in my case, there is no problem with ice core CO2 (neither with historical CO2 levels over the oceans), as the 0.3 K temperature increase in the period 1900 - 1950 causes an increase of about 0.9 ppmv CO2, which is within the accuracy of the ice core measurements, the rest of the observed increase is due to human emissions.

Global warming Increase in average global temperatures of the atmosphere and oceans over the past 100 years.

That reduces the increase of CO2 in the atmosphere somewhat, but as there is still an increase, the oceans are more important as temperature / CO2 regulator on medium term, while vegetation is faster on very short term (over the seasons CO2 goes down with temperature, over a year, CO2 goes up with temperature).

The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate change is real because of rising surface air temperatures since 1880 over land and the ocean, ocean acidification, sea level rise, glaciers melting, rising specific humidity, ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.

The main dynamical driver of the monsoon is therefore the positive moisture - advection feedback (Fig. 1 A): The release of latent heat from precipitation over land adds to the temperature difference between land and ocean, thus driving stronger winds from ocean to land and increasing in this way landward advection of moisture, which leads to enhanced precipitation and associated release of latent heat.

Perhaps the «unexplained» increase in late 20th century temperature has simply been a response to decreasing humidity over the oceans?

Similarly, Matthew England and colleagues reproduced observed temperature trends by providing the model with the pronounced and unprecedented strengthening in Pacific trade winds over the past two decades — and the winds in turn lead to increased heat uptake by the oceans.

Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).

From the article: A new study released Monday found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse gases related to global warming.

If there has been only a fairly small change in ocean heat flux over the last century and the ratio of global increase in surface temperature to increase in forcing is low (as the evidence certainly suggests), then it follows that climate sensitivity is low — perhaps of the order of 1.5 C.

And while temperature should decrease the total amount of carbon in the upper layer of the oceans, we see an increase in carbon (and a decrease in 13C / 12C ratio)- Ice cores, tree carbon and coralline sponges all give small 13C / 12C variations over the Holocene, but all show a steady and ever faster decline since about 1850.
