Lunatics often say that the decrease in the ice in the NH far exceeds the small increase in the Southern Hemisphere. Rarely do they think beyond that point.
But, look at the anomaly graph below.
There’s a couple of things we can see here. Yes, there was a slight incline in the trend from 79 through 2000. For the critics and people incapable of seeing this obviousness, I’ll supply the graph and the tend through 2000.
Yes, a nice gentle upward slope. But, what’s gone on since the new millennium?
The ice gain has has significantly increased its rate.
In the past, I’ve posited that something or some things still unknown to me, have changed circa 1998-2001 in climate considerations. Well, not things that changed, there are many things which have changed, but, making attribution, thus far, remains unconvincing, in my mind. Sun activity? Maybe. ENSO? Sort of. PDO?
AMO? Maybe, but, other than the sun activity, we don’t know if these things are causes or effects.
But, we know something did change which affected this …..
But, you know what we absolutely know didn’t change? The increased rate of aCO2. In fact, we’re gaining more quicker than we did prior.
I’m not ashamed to say I don’t know what drives our climate. It isn’t that hard to say. But, I’m pretty sure CO2 emissions do not. They don’t appear relevant to much of anything.
I liken CO2 to the earth as I would a water soluble vitamin to the human body, like vitamin C. Yes, you need it, and it is very important to health. But, once you exceed a certain limit, then nothing happens, you just pee out the excess.
