All the variation in temperature was mostly due to Milankovich variation in earth's orbit.
You find it all so simple, don't you? That tells a story.
Look up the Milankovitch cyles, and you'll find more problems with it than evidence. There's not doubt that insolation levels will vary with the cycles. That's ALL.
There is no evidence that they have dictated climate. Some ice cores match at a superficial level, but not in the way that they should. The problems with Milankovitch are big and numerous.
But it's all so simple to you, isn't it? A headline is all you need.

There was no CO2 forcing because the level of CO2 was too low, CO2 lagged behind. Now we are seeing CO2 driven temperature changes. FACT.
OK, so now you admit what I've said so many times, the CO2 has NOT been shown to force the climate. Good. At least you're not a bleeding-obvious denier.
So what you're saying is that CO2 hasn't been a climate driver in the past 400,000 years, but now it will.
That's fair enough. Your guess is as good as mine.
The IPCC say it's about 9 to 1 odds that the warming we see is related to human-released CO2. They are very vague, deliberately so. CO2 only rose significantly about sixty years ago. But they include warming from about 120 years ago.
Nice double standard.
I disagree with the 9 to 1 odds. I think it's the other way around. But just like the IPCC, agree that there is a chance either way. We don't know.
All there is, is computer models, to say that the current warming is human-caused. And you can make them say just about anything you like.
So all there is is a tiny bit of warming, and a bunch of computer models. I'm hanging on to my overcoat, thanks.
By the way, there has been no warming for the last ten years, and Arctic ice is growing, year-on-year.
