Reboot Congress for the twitter link to this fantastic article about how Climates change, all the time, and we know it.
How 'bout some science?
"For small changes in climate associated with tenths of a degree, there is no need for any external cause. The earth is never exactly in equilibrium. The motions of the massive oceans where heat is moved between deep layers and the surface provides variability on time scales from years to centuries. Recent work (Tsonis et al, 2007), suggests that this variability is enough to account for all climate change since the 19th Century."
To which I say "blam!"
I've written about this in layman's terms here, here, here, and here, here, here, here, and I'll stop here. Let's just say I have a thing against junk climate change science, ok?
