Do we trust scientists or not?

'Seven experts responsible for evaluating the threat of natural disasters in Italy have been charged with manslaughter for failing to give sufficient warning about the L'Aquila earthquake in 2009.'

Meanwhile, front page of this week's Guardian Weekly, 'World Climate now 'on the brink: Emissions hit record high despite recession. Dangerous warming now can't be avoided'.

There is now no way temperatures will not rise less than 2 degrees Celsius, which was the goal to avoid dangerous climate change. There is now 'around a 50% chance of a rise of global average temperature of more than 4 degrees C by 2100. Such warming would disrupt the lives and livelihoods of hundreds of millions of people across the planet, leading to widespread mass migration and conflict. That is a risk any sane person would seek to drastically reduce.' So says Professor Nicholas Stern of the London School of Economics who wrote the influential 2006 report into the economics of climate change.

We don't have the sense to save ourselves. Who will we blame?
