Some interesting research done by researchers at Columbia University on CO2 levels. They dated the amount of boron isotopes in plankton shells off the coast of Africa. Boron is emitted by volcanoes and is absorbed by plankton in proportion to seawater pH which is linked to CO2 in the air. (Gary Hemming has spent 10 years developing the relationships and published his results in "Science". ) The research shows that CO2 over the last 2.1 million years has not changed much holding at 280 parts per million whereas today it is running at 385 parts per million.
Other studies show that CO2 hasn't changed much over 20 million years. It had been thought that CO2 increases periodically and triggers ice ages. That has now been disclaimed. There are other theories as to why ice ages occur. Finally, older climate studies show that there was a large increase in CO2 55 million years ago which led to a large extinction of bottom-dwelling creatures and dissolved the sea shells as seawater became more acidic from the CO2. The inference is that we need to be mindful of how much CO2 we are pumping into the air. ----- Original Message ----- From: "Bob Calco" <[email protected]> To: "'ProFox Email List'" <[email protected]> Sent: Saturday, October 10, 2009 10:10 AM Subject: [OT] What happened to global warming? >< http://news.bbc.co.uk/2/hi/science/nature/8299079.stm> > > - - - > This headline may come as a bit of a surprise, so too might that fact that > the warmest year recorded globally was not in 2008 or 2007, but in 1998. > > But it is true.
