this has been done on a daily basis in real time since about 1958 at the mona loa observatory in Hawaii. and indirectly by sampling ice cores from both Greenland and Antarctica- the Core record from Antarctica goes back some 600,000 years as I recall. CO2 levels are now higher than ever-from this record. > > Logan Vilas > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Joe Street > Sent: Thursday, July 27, 2006 10:35 AM > To: biofuel@sustainablelists.org > Subject: Re: [Biofuel] Fluorescent fuel? > > Yes that's true.
