[Terrapreta] Ice-age anyone? - RWL part 2.

          Good points Peter. It's good to see someone has identified a
positive use for that CO2 we Canadians are preparing to pump underground at
great expense.

 

          The Ruddiman articles are intriguing. I prepared a short reviews a
few years ago.

Human use of fossil fuels and energy during the past  hundred years is
popularly  known  as the root cause of climate change.  The so-called
developed world is most often cited as the responsible agent. Primary blame
is often assigned  to countries such as Canada and the United States which
are deemed to be "energy hogs". Little thought is given to the benefits of
energy use which we all enjoy. Little credit is given to the science and
technology which has developed modern energy sources for the benefit of all.

A recent paper in the journal "Climatic Change" suggests that human induced
climate change  was initiated  with the development of agriculture,
thousands of years before  use of fossil fuels and extensive agricultural
development in North America. This aspect of climate change  has been
begging for some thought and study. Computare's  introduction to the paper
is provided here

Update - Professor Ruddiman has just published another paper on this topic
in Scientific American. A brief review is provided here

Hi everyone

Yes, of course the preponderance of evidence is that not only are we in for
global warming but also that there is a significant risk of passing a
tipping point for irreversible catastrophic abrupt climate change.
