A month or so ago I was listening to an NPR interview about insects. The interviewee said that the insect population in Germany has declined something like 75% in 25 years. He noted that people don't tend to notice big changes over the span of a couple decades, which is a good point, and helps explain why climate change will probably never be seriously tackled.
It will be tackled through adaptation. Some coastal cities may die. Others may have to spend a ton on remediation. More people will migrate inland, and farming centers will shift.
It’s far too late to stop it with prevention, though there is still value in trying to cut CO2 when possible to blunt it a bit.
