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.
- sharpshadow 2y agoThe earth moves in milankovitch cycles around the sun which are a mayor contributor to warming and cooling cycles. The ice core data shows also that increases in CO2 concentration followed after the temperature rose first which could correspond to the milankovitch cycles. The greenhouse effect takes places which leads to faster temperatures rises and humans are definitely contribution to that, which might already have changed how the world will look in the future. Could youn link me to the record temperature rising right now in the last 100 million years please?

- taylodl 2y ago> The earth moves in milankovitch cycles around the sun which are a mayor contributor to warming and cooling cycles. Yes, and that is extremely well-known. As are solar cycles. We have a pretty solid understanding of the natural cycles affecting climate. That's how we're able to assess humankind's impact on climate change above and beyond the natural variation.
- sharpshadow 2y agoWe also well know that CO2 is released with rising temperatures in different systems and absorbed with falling temperatures. As mentioned before the ice core data shows exacly this a release of CO2 after a temperature increase. One could argue that it's a false correlation between temperature and CO2 especially since we talk about a concentration of 0.04% CO2 in the atmosphere. But that are just talking points I don't know the answers but seemingly you know the truth and ignore a conversation.
