I’ve been worried about this from the first time I saw such a chart... which, I think was about 40-50 years ago. A blink on a geologic scale. But, even as a teenager, I was able to quickly understand that: We’re NOT in control of our climate, and.... eventually, it’s going to get ICY again.
And while we go back and forth on the short term trends, This clearly shows the decline of solar absorption over the last 8,000 years.
This cooling didn’t just start yesterday... It started 8k ago and we are just now starting to feel this change. In the bigger timeline there is a slight delay of several thousand years.
So your gut instincts were right on track. Like you say, even this 8k is just a blink on the geologic scale and timeline.
... and you can't grow much corn or wheat on a glacier. Cooling is much more of a threat to humans than warming.
