Science 2.0 has gradually been colloquially Smurf'ed into meaning many different things but at its core we have always intended to reboot science for the 21st century by modernizing publication, participation, communication and collaboration.   Collaboration was always known to be the tricky part and little progress has been made but groups like Mendeley are at least making it possible to better organize research.

Politicians do not really understand science, they are in the policy business.  And environmental activists do not understand science, they are in the advocacy business.  Both claim to love science when it suits their agenda.  When they are together, as with recent tax schemes designed to penalize carbon usage, it can be very bad.    But everyone knew this except politicians and activists, who only believe in 'the miracle of capitalism' while they are legislating the parts they don't like out of society and insisting it will flourish if they control it.

In 2006-2007, the heyday of CO2 hysteria, we noted that a large problem that we could control without wrecking the global economy (not that it mattered, the global economy was kind enough to wreck itself) was methane production. 

Methane has 23X the impact on warming as CO2 and is caused by plants and animals - as impractical as shutting down all commerce sounded to sane people not in the anti-science environmental movement, cutting down the Amazon to remove dead plants causing methane was equally silly.
