But the broad correlation shows the same trend regardless of those short-term (in the grand scheme of things) cycles. I remember seeing this infographic a few years ago and it really hits home how big an issue the rate of change is, regardless of other natural cycles. https://xkcd.com/1732/...

It's the broad trend that is important though. The atmosphere changes a lot slower than temperature so doesn't experience the same level of short period variation. But those variations are small enough that they are not significant compared to the overall trend, it's referred to as 'noise'...

I have a PhD in science (not that has any significance) and I learned that when you find a correlation and then you can understand the mechanism (with evidence) by which the causation happens, you generally accept it unless there emerges any evidence to the contrary. We have that - CO2 is a...

I agree with you here somewhat (and thanks to BrickTamland for giving some good suggestions on what people can do) - to an extent we are helpless as individuals as to what we can actually do as our individual impact is so tiny compared to big organisations and governments. But this is the...

What evidence would you need to convince you to change 'believe' into 'know'? Because the evidence is there, as far as any scientific theory: - we can prove that there is a sharp increase in atmospheric CO2 since the industrial revolution - we can prove that the extra CO2 comes from fossil...

If we entertain, for the moment, the idea that CO2 and temperature rises aren't linked. Then by reducing the amount of CO2 we emit, and possibly trying to capture some of it back from the atmosphere, by that logic we won't be affecting the planet's temperature. So I'm not sure what you're...
