Lacking proof...
In the time this thread has been running that volcano in the Pacific has put out more CO2 than Brazil will put out in 2010.
Unless the venting stops in the next few weeks it will surpass the annual CO2 output of China. If the venting continues for just a few months, which this volcano has done in the past, the CO2 output from one volcano will surpass the 2010 CO2 output of all mankind.
Man's contribution of cooling or greenhouse gases to the air is nothing compared to Mother Nature.
Man put out massive amounts of sulfer dioxide during the industrial revolution and well into the 20th century. All that sulfer dioxide from burning coal never triggered global cooling before the western nations started filtering it in the later part of the 20th century to prevent acid rain.
The world actually was warming in those years as it came out of the Little Ice age.
Yet Mt Pinatubo erupted and in one day dumped millions of tons of sulfer dioxide into the air that caused global cooling for 3 years in the 1990's.
Even global warming scientists have no answer to what caused the warming period from 1850 to 1950 that raised global temperatures.
They also have no explaination for the Midieval Warming Period from AD 800 to 1300 that preceeded the Little Ice Age.
To take the easy way out and blame man for any modern day warming is a copout on trying to find out what happened to trigger the prior warming events.
We may be chasing CO2 ghosts while the real cause of global warming comes back to bite us.
