[Terrapreta] the most terrifying video...climate change

[Gerald Van Koeverden]

If Svensmark's hypothesis holds up over time from many different  
approaches to the problem, then it will eventually become the  
accepted explanation by scientists.

But until then, the prevailing scientific explanation for it has to  
do with our pollution of the atmosphere, of returning the atmosphere  
to a condition many millions of years ago when there was a much  
higher concentration of CO2 in the atmosphere.  By releasing all that  
carbon from those very long term "sinks" - coal/peat/oil deposits -  
we are re-creating a pre-historic climate of extremes...

Just like the idea of continental drift, it took many years for the  
greenhouse thesis to go from a being the idea of only one person to  
that of accepted orthodoxy.  It is possible that Svensmark's will go  
this same route, though 99% of new theories in science are eventually  
abandoned.

So do we act on what we believe with what we already know, or do we  
wait until we're sure from hindsight - when it's probably too late??
