There is a plausible explanation for how carbon dioxide molecules could interact with water molecules thereby forming a solution where the carbon dioxide is the solute and water is the solvent (as it usually is). The weak inter-molecular attractive forces rely on the polarity of the water molecule and the high density of electrons at either end of the
When a bottle or can of carbonated beverage is opened the carbon dioxide is allowed gas to come out of solution. This is because there is a pressure differential between the carbon dioxide in the liquid and carbon dioxide in the air. The pressure in the liquid is higher than the pressure in the air so the carbon dioxide moves
This article and associated video describe the findings of researchers who undertook core drilling at Lake El’gygytgyn, a lake that sits today inside a basin formed by a meteorite that struck the earth 3.6 million years ago. An associated video allows us to hear the enthusiasm and details as researcher Julie Brigham-Grette describes the findings of this remarkable discovery.

Lake El'gygytgyn (also called, Lake E) permafrost drilling started in mid-November of 2008. The ICDP (International Continental Drilling Program) is posting news reports and images to this blog several times each week. Check out early reports from Lake E.
