Since instrumental records are a nanosecond of earths weather record they are just as relevant as how many times i have farted in the last nanosecond, not once. Therefor I never fart. Silly huh![]()
You know what is relevant?
The effects of temperature change on the things we eat, both in rate of change and magnitude of change.
Why so US centric ? Much of Europe has had crap summers for the last 4 years and here in the UK its been the coldest wettest summer in living memory. Theres a whole big wide world outside of the US you know . Get an atlas (you should find one in any good rare book shop over there) and you'll see I'm not kidding.
And as you've been shown many times now that is well within the natural norms of recent millenia. Why is it so difficult for you to take this simple fact on board or do you simply choose not to ?
Climate has changed before, therefore no harm can come of it?
Its like worrying about an asteroid strike and just as pointless
False comparison based on the mistaken assumption that it's impossible for humans to influence climate.
Given that nobody has yet shown that to be possible its no mistaken assumption, and to date the computer models that try and say that it is arent worth squat :roll:
Has anyone ever said it's impossible that man could effect the climate? seems like what I hear is people saying they don't believe man is changing the climate, kind of a big difference.
Really? Can't think of one thing anyone has brought up that would make it potentially possible to have some influence on climate?
Say, somehow altering the rate at which energy escapes from the earth to space? Any possibility that might have any influence?
The asteroid example gives the "outside variable we can't change" impression.
If you start worrying about every hypothetical scenario that is 'potentially possible' there will be no end to your hand wringing
We dont know anything like enough about this to tell one way or the other though Roy Spencer brought out a paper last year showing far more heat was escaping into space than was previously believed.

If you think we can somehow 'control' climate by modulating our minute contribution of a tiny trace gas then you really have got it bad
.Ahh yes the old "trace gas" meme
There are substances that can kill you at 400ppm. You can't just handwave the question with "there's not very much of it" because "very much" is some arbitrary concept you came up with in your own head.
Climate "skeptics" would have a better argument if they would stop repeating logical fallacies like this.
"Climate has always changed!" So? That's not evidence that the current change is natural or that humans can't cause changes.
"It's within natural parameters!" So is Venus. That doesn't mean it's healthy.
"It's a trace gas!" Arbitrary and irrelevant.
"Al Gore flies a jet!" Infrared radiation doesn't particularly care what Al Gore does.
"There isn't any evidence." Straight-up lie right there.
Incidentally, you'll have to forgive me if I don't take the word of a lawyer from the Heartland Institute at face value, as you seem to have done. Especially considering his blatant and egregious misrepresentation of a CERN study regarding cloud formation. You know why I keep telling people to go with scientists as primary sources instead of letting journalists and the like translate science for you? That guy. That guy is why.
Opinions ,opinions, opinions and still no scientific evidence .... ahhh well same sh*t different day :roll:
The model has no realistic ocean, no El Niño, and no hydrological cycle, and it was tuned to give the result it gave. Most of what goes on in the real world of significance that causes the relationship in the paper is ENSO. We have already rebutted Lindzen’s work on exactly this point. The clouds respond to ENSO, not the other way round [see: Trenberth, K. E., J. T. Fasullo, C. O'Dell, and T. Wong, 2010: Relationships between tropical sea surface temperatures and top-of-atmosphere radiation. Geophys. Res. Lett., 37, L03702, doi:10.1029/2009GL042314.] During ENSO there is a major uptake of heat by the ocean during the La Niña phase and the heat is moved around and stored in the ocean in the tropical western Pacific, setting the stage for the next El Niño, as which point it is redistributed across the tropical Pacific. The ocean cools as the atmosphere responds with characteristic El Niño weather patterns forced from the region that influence weather patterns world wide. Ocean dynamics play a major role in moving heat around, and atmosphere-ocean interaction is a key to the ENSO cycle. None of those processes are included in the Spencer model.
Well here's a post I did ages back.

If you think none of that counts as evidence, well, I don't know what to tell you.
It does not count as empirical evidence because the basic climate sensitivity value for CO 2 is an unknown variable ergo it cannot therefore be empirical. This is obviously a fundamental problem given the whole doomsday hypothesis rests on the predictions from such modelling. Models as I hope you know are mathematical constructs whose accuracy depends on the reliability of thier inputs so garbage in = garbage out .
Obviously it's not comprehensive proof and is just a tiny part of the big picture, but to call it "no evidence" is just plain dishonest.
Most of that 'big picture' you allude to is entirely unknown to us as yet ,so making firm claims that it represents 'evidence' of any sort is a highly subjective interpretation of it.
Do you have a doctorate in climate science? How about a master's degree? No??? Then even if all the evidence were delivered to your desk in a pretty box with a bow it wouldn't do you one bit of good. You'd still have to rely on someone else's opinion to make any sense of it.Opinions ,opinions, opinions and still no scientific evidence .... ahhh well same sh*t different day :roll:

Given that this AGW hypothesis is wholly dependent on mathematical constructs (and I can do math) it gets itself into extremely murky waters when the inputs are either unknown or subjectively valued to fit a certain hypothesis. They arent even close to knowing what all those variable are yet much less thier values and interactions with one another . Here is why these models will always fail.

This is why direct observations and comparing those with the known paleoclimatic records are a far more reliable way of making determinations about what is or is not abnormal about todays temperatures or rate of change. Believe me if James Hansen himself was debating me I'd be putting forward those same points to him and I'd demand proper answers too.
