Sorry. We know that to be false. No one is debating that, if left to its own devices, Earth is in the process of warming since the last ice age. That's a scientific fact. Earth would be warming even if humans weren't around.

What's also a scientific fact is that humans are accelerating that warming trend - and that's a problem. If the Earth were warming up on its own, it would do so much more slowly, and ecosystems would have lots of time to react. This has happened several times over Earth's past.

The difference now is humans are accelerating the warming. We can find no evidence of any other time in the past 100 million years of Earth warming up faster than it is now. We're limited to 100 million years (give or take) because that's the limit we can measure Earth's past climate. It's the slope of that temperature gradient that's the issue and humans have increased that slope, mostly by our dumping of CO2 into the atmosphere.

All this article "proves", as you say, is what we've known all along: by some measure climate change means some things will get better, other things will get worse. In the aggregate we expect things to get worse.
