That should fill you in on who is making the images and where the data comes from.
Nice you-don't-know-nothing snap, though. We've discussed this issue enough to know that neither of us are climate scientists moonlighting on forums. |
Don't take that as a negative. I'm in the same boat. We are not experts. Also, I don't buy the whole model as provided as I will describe below.

Who are "The Biology Cabinet"? I can find one scientist behind this, Nasif Nahle. Google isn't being very helpful either.
The NOAA don't seem to agree. HERE

I know that Nahle has used some NOAA data, but I'd prefer to take it from source. Also, the biocab graph isn't labelled very clearly, there's a lot of stuff going on in it that ain't labelled.
I said it's never warmed so much so fast. Not that it's hotter now than it's ever been.

On the NOAA front - they have only run simulations, and while they may be a good at being close to a few degrees, this is the also the very problem with a simulation. You must also look at record data from the period which their simulation does not incorporate. Read the source material for the link I provided. It shows you that NOAA is not the exclusive source since they can only guess at what was what at any certain point in time unless it was extremely hot or an Ice Age. What is also included is record data from the period.
Regardless of what is or isn't the case with the data, what I really think is happening here is a case of people all a sudden realizing they have a ton of data for the 20th century - the first time EVER! They see a temp fluctuation and then freak out and speculate on what could be the cause, when this is probably quite normal. This is what is happening - they are freaking out because they think we are the only force at work here. People need to take a chill pill and follow things for much longer than the short term data they actually have. It could very well be that in 5 years, things cool off and then they'll freak out about that and say we did too much. 80%+ of all climate change will have no direct result of human activity, intentional or not, so I speculate that mother nature will correct the small percentage we are contributing at some point.
In the meantime, it is not a bad thing to try to limit our contributing factor in this matter either. What I am more concerned about is my own health from the emissions polluting our atmosphere than have an inch rise in sea level or worse weather. It is the very pollution that concerns me much more.

PS. How did this thread get so far off topic? Maybe if this discussion is going to continue, you start a new thread on it. This thread is supposed to be about nukes.
