What is the percentage of CO2 in the atmosphere?

I'll help you out here, it's 0.04%.

200 years ago, it was around 0.033%. Given the worlds population has gone up by several billion, and almost every country is now chucking out emissions, it seems a rather small increase. Maybe, just maybe, CO2 isn't the real problem. It does smack a bit of convenient science to blame CO2 in that case.

The 'pre-industrial' number is generally given as around 270ppm, we're now at 400ppm. In other words, an increase of about 40%. Not trivial. The uncontested science translates this into around an extra 1.9W per square metre not escaping into space (Other greenhouse gases are also available) . We are in a radiative imbalance.

Objects with a radiative imbalance must get warmer, unless Donald Trump repealed the 2nd law of thermodynamics.

...and if you read the "against" arguments presented on here, "science is wrong" because it's all about money.

That's because they get their science from the Daily Mail.

Trump's victory probably (I mean, who knows what he's going to do, this is a man who lied on average 20 times a day during the campaign) means a pause, at best, in attempts to reduce GHG emissions. So we get extreme hypothesis testing on the only planet we have.

I only hope that those who complained that their ability to fly away on foreign holidays might be constrained don't end up with nowhere worth flying to.

Outdoor temperature has dropped to -10c. That is very cold weather but in climat terms it’s global warming.

I must have missed a memo. Did somebody predict the end of weather?

'Stochastic' is a beautiful word.

Anyone know what the ideal average temperature of the earth should be yet?

The "ideal temperature", even if we can collapse the entire world climate into one number, is not the important thing. It's the RATE of change. The world has been MUCH warmer and MUCH colder than it is right now. Life is not equipped to cope with sudden change in climate as attested to by the 5 or so mass extinctions some caused by the emergence of life.

Sorry pal, you're really talking tulipe. What do you define as "pre-industrial"? I gave you a fact that you can't refute except with a blithering scientific hypothesis. Oh, I get it, you just changed the goalpoasts and the rules because you didn't like the result.

Edit - is there a way of spelling out the word S H I T without it being re-edited to tulip?

The standard definition is 1750. As I said the existence of a radiative imbalance is uncontroversial, adding up all fluxes gives a net forcing of +0.6 watts per square metre.

If the incoming energy flux is not equal to the outgoing energy flux, the result is an energy imbalance, that amounts to net heat added to or lost by the planet (if the incoming flux is larger or smaller than the outgoing respectively). Earth's energy imbalance measurements provided by Argo floats have detected an accumulation of ocean heat content (OHC). The estimated imbalance was measured during a deep solar minimum of 2005-2010 to be 0.58 ± 0.15 W/m². Later research estimated the surface energy imbalance to be 0.60 ± 0.17 W/m².

This is fundamental, uncontroversial science.

Play them at their own game

And do we know yet what the optimum climate for the world actually is?

so rates of change now are considerably faster than at any time in the last 500,000 years?
