For some 6 years Bush followed the lead of the right and said we need to study it more. Finally even he came around to admitting what is overwhelming obvious. Now here are people starting the same tactics to achieve their short term agendas, whether it be a philosopical hostility towards the scientific age, or the loss of possibilities to make money, short term.
If you follow science on a science oriented site or magazine you will see almost every day more evidence of what is happening. Just ask an Eskimo who is being forced relocate as the sea rises. Or maybe the fact that nearly every migrating bird species in the US has extended its range northward as things warm, same in Europe. Or that they are starting to grow champagne grapes in the UK. Or that almost all of this is happening faster than almost anyone predicted.
As for the emails, much of it is being spun to appear to be what it is not. Sort of like Palin interpreting the consoling sessions for elders (she supported this when the Republicans proposed it) as death panels. Truth, it just gets in the way.
But there is some legitimate complaint. No scientist should ever deliberately conceal and or worse, deceive. That runs totally counter to the principles of science. There should be managers removed from their posts for this. I am afraid that a few scientists showed that they are indeed human, and gave in to the temptation to deceive.
But from everything I have read this is all just a whisper in the midst of a hurricane. It makes no difference. The rising seas, the receding glaciers, the near complete loss of permanent sea ice in the Artic, the movement of plants and animals towards the poles, the acidification of the oceans, it is all there for anyone willing to open their eyes.
