Climate warming 'seesaws' between the poles

Antarctic ice-drilling reveals linked cycle of warming and cooling.

Researchers trying to understand sudden, seesawing changes in the Arctic's prehistoric climate have found some answers in an unusual place: buried in the Antarctic ice, half a world away. Their work could help to predict the future consequences of sudden polar warming.

Oceans and Global Warming

Number of science reviews in this field have linked solar activity to the climate change. Rise in global temperature is always accompanied by the rise in CO2 concentration. Human contribution may be significant but it is not critical. By far the greatest amount of CO2 is released by the world’s oceans; they are also the largest absorbers. The release of CO2 is not, but its absorption is affected by the Sun. The culprits are UV and gamma radiations reaching the oceans’ surface during periods of high sunspot activity.

Some 2 years ago I wrote:

Increased solar activity results in an increase of the harmful radiation, reducing bio-mass of the oceans’ surface plankton trough process of sterilisation by irradiation. Result of this is reduced uptake of CO2 from the atmosphere and rising in the ‘green-house’ effect. Reverse process takes place during reductions in the solar activity.
