No believing.
Having said that, I've remaining issues with the climate change "camps". The crucial question being: to what extent do increasing atmospheric greenhouse gases contribute to global warming, that is, what is the 2xCO2 (the doubling of atmospheric CO2) sensitivity of the planet? I don't think there has been an adequately shown answer to that, although a range of estimates have been published.
But should this answer truly matter in determining policy to reduce and moderate the current excessiveness of carbon output? I refer to the posts of Bruce and poemless above.
