Over the years I have heard droughts, extreme cold, extreme heat, heavy snow fall, no snow fall, heavy rain fall, active hurricane season, calm hurricane season, etc... all blamed on man made global warming. Are there any weather conditions that could falsify this theory?

What Could Falsify Man Made Global Warming Theory?

If you're asking what "weather" could falsify global "climate" change, you need a primer on the difference. This is a Pauli question. "It's not even wrong."
If you wanted to falsify man-made global warming by asking the right questions, however, you could, conceivably, show that all of the basic science showing CO2 absorbs infrared radiation was faked, that all of the measurements showing rising CO2 levels were faked, and that the isotope measurements showing the excess CO2 was from fossil fuels were faked. Basically, you need to uncover a vast, global conspiracy among climate scientists.
Or, you could accept what everyone else outside the lunatic fringe and the paid merchants of doubt accepts.
Anthropogenic global warming is settled science.

How's that working out for you?

The greenhouse effect exists. We measure it on Earth and on planets like Mars and Venus. None of those planets would have the temperatures they do if it weren't for the greenhouse effect.
Carbon dioxide is a greenhouse gas. That's basic physics, and we've measured its absorption properties.
Humanity is putting carbon dioxide into the atmosphere, and CO2 levels are going up. Again, measured in a variety of ways.
So, if you want to falsify concerns about anthropogenic climate change, you've got to knock one of those three pillars out. And that's almost impossible to do, given how thoroughly the above have already been tested. Put another way, we've already subjected it to lots of falsifying tests, and it's passed.
Now, back to your question: there are two ways to think about this. One is, could there be another influence on the climate, one beyond all the ones we've studied and accounted for, but not yet discovered? That could mean that, although the greenhouse effect exists, it will be moderated by something else entirely - something that's big, but we've somehow managed to completely miss. I don't think that's especially likely, and it probably wouldn't reveal itself through weather events anyway.
A more useful question: we predict a lot of weather consequences from a warming climate. Could specific classes of weather events, if occurring in sufficiently large numbers, falsify these predictions? The answer is yes, lots of them. But it's not an area i know especially well."Any sufficiently advanced stupidity is indistinguishable from trolling."

Weather cannot falsify a model for climate change, just as a single person's income cannot falsify an economical model.
As for discoveries within climate science, there are lots of observations that could falsify current theories. Climatology is what Imre Lakatos would call following a 'successful research programme' and as such makes good predictions and gives handholds for continuing research. This means that old knowledge will be critically revised. I don't agree that climate science is settled; the basics, like the greenhouse effect, are settled, but there is a lot to be done still.

Originally posted by seer View PostYes, I would like to know what those can be since for just about every weather event imaginable the climate change card is played. We are experiencing one of the coldest winters in recent memory - why- climate change, of course!
So, the question we need to examine is not whether this particular case is due to climate change, but whether a warmer climate will make this particular shift more common or not. One way to do that would be to set a weather model with preindustrial conditions and run it 1,000 times, and see how often we see this pattern. Then set it to current conditions, and see if the numbers differ. Etc. etc.
The key thing is that doing so requires a LOT of computer time. If a weather event is in progress, that means that nobody's had the time to do all the computer work to ascribe it to climate change or not. So, if you hear something like "it's cold because of climate change", it's probably someone who has no idea what they're talking about.
The exceptions to this: if we had a polar vortex last year, then the simulations might be done in time for this year. Or someone's done some general work, and found conditions like this will be more common in a warming planet. So, your best response to someone making the claim "this weather is because of climate change" is probably to ask "how do you know that?""Any sufficiently advanced stupidity is indistinguishable from trolling."

To illustrate with an example. Let's say you have central heating in your home. You turn it on, the water starts to flow through the system and all radiators become hot as they should. This you observe, and you have no reason whatsoever to doubt your observations. However, the room isn't getting warmer. Would you conclude that, in spite of everything you see, the radiator has broken down? No, you'd start looking for some other explanation. Somehow, the heat is disappearing from your home: that would be the likely conclusion. Perhaps you just need to close a window.
If temperatures don't rise, the first reaction would be a similar hypothesis. Something would be slowing down the warming due to the greenhouse effect. Perhaps this something is in itself connected to CO2 or another greenhouse gas. Perhaps it would be unrelated - it's a hypothetical situation, I don't know what could do this. But the basic mechanism that warms the planet - the greenhouse effect - would still be in place. After all, it has been keeping our planet at a nice temperature for millions of years already, it's just a bit too much at the moment!
Yes, I would like to know what those can be since for just about every weather event imaginable the climate change card is played. We are experiencing one of the coldest winters in recent memory - why- climate change, of course!
In my country this was also done for a couple of years. At one point climate change was even blamed for lambs born early in the season. We had a joke that if Easter came early that year, it was due to climate change. Now the weather is seen as normal variation within the general climate by most.

therefore AGW must be a fraud perpetrated by tens of thousands of climate scientists."
