Climate deniers don't deny climate change any more

So what causes them?

 

No but at the same time you have produced no evidence to explain the current warming we are seeing

 

???? The fact that the last ice age ended with a more rapid increase in temperature WITHOUT any burning of fossil fuels.

 

I'm only interested in the increase in global temperatures and climate change and the increase in atmospheric CO2 in my lifetime.

 

So what!!! I'm only interested in the huge spike in atmospheric CO2 from human activity and it's effect on global temperatures and climate change within my lifetime, and not whether YOU used a thermometer or your finger to measure Antarctic temperatures 800,000 years ago.

 

We are getting closer to understanding each year and assigning a specific cause for each ice age - BTW good summation - add to it disruption of ocean currents and the negative feedback from changing albedo caused by formation of vast ice sheets
Changes in CO2 definitely played a part https://www.princeton.edu/news/2020/12/10/what-caused-ice-ages-tiny-ocean-fossils-offer-key-evidence

 

That could be the source of your confusion. If you see a river near your home flood higher than youve ever seen it flood in your lifetime before, you might assume the calamity of global warming is coming to get you. But when you learn from Grandpa that it was what they call one of them 100 year floods, occurring on average every 100 years, youre going to look silly as you do here.

 

Is any of that happening now?? What is causing the current warming?

 

Noooo I have spent years reading the research surrounding this and have even read the IPCC reports but somehow there are people who still think they know more than the thousands of climate scientists world wide who contribute to those reports

Amazing!

 

That's your issue not mine if you want to add another red herring to your collection. But your red herring doesn't change the fact that global temperatures and atmospheric CO2 from human activity have increased in my lifetime.

 

Something Ive never denied. Looking for the next strawman?

 

Get a better argument.

 

The cyclical end of this ice age.

 

We do know all of them occurred without the effects of mans burning of fossil fuels is the point. All natural causes.

 

Yep, and CO2 is still rising. We are at the very beginning of the effects of Climate Change. It will get a lot worse for generations to come.

 

Nope.

 

I prefer anomaly graphs. You say potato, I say potahto . . . .

 

Why do you always have to pretend you are responding, but actually change the subject? It's really quite despicable. Keeping records is not the same thing as adding a color, and you know it.

 

Problem is, that's a graph of temperature in the lower atmosphere, not at the surface, so the actual temperature looks really cold, and is not very informative in terms of understanding temperature changes over time.

 

You mean the strong correlation that you repeatedly claim, even when shown repeatedly that it does not exist?

 

The correlation between atmospheric CO2 and rising temperatures absolutely does exist, and it is undeniable.

 

Your lifetime. What's so scientifically relevant about you, personally, when the subject is climate change?

The appropriate interval of analysis for climate science depends on the scale of the variations in question. If we want to understand seasonal variation, we need to look at a significant number of recent years, not just one or two. If we want to understand the kind of century- to millennium-scale warming that has occurred since the Little Ice Age, we need to look at a number of cycles on that scale, probably going back ~10Ky to the early Holocene, not just your lifetime. If we want to understand the glacial cycle, we need to look at the whole 2.5My Pleistocene, not just the latest glacial period. And if we want to understand the long-term effect of CO2 variations on climate, we need to look at the whole 540My Phanerozoic, after the earth's atmosphere lost most of its CO2.

No, just an observation about your lack of qualification to opine on scientific matters.

 

Sure, just as there is a correlation between rising temperatures and global production of thermometers, or men's trousers. But it is not strong, and the paleoclimate record proves that until the 20th century, it existed more because temperature affects CO2 than because CO2 affects temperature. And given the modest effect of temperature on CO2 in the paleoclimate record, the effect of CO2 on temperature must be quite modest, and certainly nothing to be concerned about.

 

Where has it been shown not to exist?
