Happamoituminen hyväksi merelle

Yleinen oletus on, että hiilidioksidin aiheuttama meriveden happamuus on suurempi kylmässä vedessä, liukeneehan siihen Henry´n lain mukaan enemmän kaasua. Todellisuudessa tilanne maailman merissä on juuri päinvastainen, kylmimmät meret ovat
vähiten happamia, kuten kuva yllä osoittaa. Asian ytimenä on, ettei merien pH:a aiheuta liuennut CO2 vaan biologinen toiminta,joka voimistuu happamemmassa vedessä.
Happamoituminen on siis eduksi merille.

"ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap.

The results of ice-core drilling and sea ice monitoring indicate there is no large-scale melting of ice over most of Antarctica, although experts are concerned at ice losses on the continent's western coast.

Antarctica has 90 per cent of the Earth's ice and 80 per cent of its fresh water, The Australian reports. Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica. The destabilisation of the Wilkins ice shelf generated international headlines this month"

A scientific scandal is casting a shadow over a number of recent peer-reviewed climate papers.

"At least eight papers purporting to reconstruct the historical temperature record times may need to be revisited, with significant implications for contemporary climate studies, the basis of the IPCC's assessments. A number of these involve senior climatologists at the British climate research centre CRU at the University East Anglia. In every case, peer review failed to pick up the errors.

At issue is the use of tree rings as a temperature proxy, or dendrochronology. Using statistical techniques, researchers take the ring data to create a "reconstruction" of historical temperature anomalies. But trees are a highly controversial indicator of temperature, since the rings principally record Co2, and also record humidity, rainfall, nutrient intake and other local factors.

Picking a temperature signal out of all this noise is problematic, and a dendrochronology can differ significantly from instrumented data. In dendro jargon, this disparity is called "divergence". The process of creating a raw data set also involves a selective use of samples - a choice open to a scientist's biases"
