Agreed. Ultimately, it's global cooling that humans need to worry about. A significantly warmer client might be uncomfortable, but we'd cope. However an ice age will destroy most human life on the planet.

Nobody here has denied that the climate changes.

That depends on the timeframe you use to calculate the average. I assume you're taking the average only for the period where temperatures were mostly lower than they are now (last hundred years or so), in which case obviously recent temperatures will be higher than the average because...

You said 'the major contributor' which means you think it's greater than 50%, right? I just asked if you could tell me in what way the climate has actually changed since the 1980s, and what exactly is the problem with the climate right now? If you can't, that's fine. I didn't really expect you...

So greater than 50% then? Do you have some evidence to back this up, or is it just your opinion? In what way has the climate actually changed since the 1980s? Please be as specific as possible and include all the climatic elements that have changed (rain patterns, storms, cloud cover...

I don't think anyone has denied climate change. The question is the extent to which humans contribute to it. What proportion of climate change do you personally believe is caused by humans? 1%? 50%? 99%?

How far does the data go back? I doubt there were many satellites measuring the strength of storms over Asia 50 years ago. Can you show me the storm records for the past few millennia so we can be sure your statement is correct?

What proportion caused by human emissions? Human emissions are one of the many things that contribute to climate change, but their impact is very small, probably negligible, compared to the natural forces that have been driving climate change for billions of years (mostly the sun and our...

Strange bet. Climate change is real. The climate has been changing for billions of years, and will continue to change for billions more years.

0.04% cyanide in the body would probably be fatal. 0.04% CO2 in the atmosphere isn't harmful at all. In fact it's probably beneficial since increased CO2 is better for plant life and increases crop yields.

The sun causes the heating. In what way, specifically, has the global climate changed? Not for a couple of decades...

So now the oceans are the biggest driver? I thought it was supposed to be human CO2 emissions? :rolleyes: What changes to the climate have actually been driven so far? Has there been more rain, less rain, more storms, less storms, more humidity, cloudier days? Precisely how has the global...

Your question doesn't make sense. The current 0.04% concentration of CO2 in the atmosphere already includes the cumulative effect of all human CO2 emissions ever.

Yes, and NASA did the same recently. Last month the media was full of reports claiming 2014 was the 'warmest year ever', based on NASA's data. But when people actually investigated the NASA data it showed that there was a 62% probability that 2014 was NOT the warmest year ever...

The point is that more CO2 is released, and at a faster rate, when the temperature is increased. Coke will keep its fizz longer in the fridge than in the saucepan. Your postings demonstrate that you don't bother to read the science beyond the small section you wish to promote. Caillon's 2003...

Nope, it's the other way around. Temperature drives CO2. Temperature leads, CO2 lags by about 800 years... http://joannenova.com.au/global-warming-2/ice-core-graph/ You can test this yourself at home. Get a can of coke and warm it up. The CO2 will be released into the atmosphere. The same...

And the funny thing is, if you zoom in to the most recent 5000 years on your chart, it looks exactly the same as my chart, with temperatures moving up and down within a +-2% range. So not different looking at all! Thanks for your contribution LibGS. It's a perfect example of not being able to...

Wow, so you're telling me a 400,000 year chart looks different from a 4500 year chart? That's amazing. Thanks for your insight. Here's another one for you. I'm betting you'll be able to find one that looks different to this one too!

I'd rather my taxes went towards useful things like schools, roads, hospitals etc., rather that being wasted in some futile attempt to prevent the climate from changing. Where do you suggest we reduce funding, in order to pay for the fight against climate change? Education? Healthcare? Foreign...

What caused it before humans started emitting CO2, and why has that thing stopped causing it today? Were you aware that the sun also heats up the atmosphere? Were you aware that there has been no warming for almost two decades, despite an acceleration in human CO2 emissions? I guess...
