re: That Human Activity is a Significant Cause of Global Warming. |

I believe all of us can cite "evidence from my own life where human activity" which has to some degree "impacted negatively on the environment."
Here, specifically, we are talking about "impacts" which affect temperature.
Anecdotal evidence is not science, yet even as anecdotal evidence may indicate "climate change," that does not equate to *global warming.*
Neither does anecdotal evidence indicative of "climate change" locally offer anything necessarily conclusive on a global scale.
I think we need to be careful about exactly what we are saying as we proceed.
As I recall, Thomas Holford is one of many who have readily conceded there is *climate change.*
The question central to the scheme which intends to tax us all for our contribution of CO2 to our atmosphere - obsessively focused on one one "pollutant" - is not just whether there is *global warming* but whether that warming is human-caused.
Climate change is shown historically as an unending cycle of natural ups and downs dependent on causes greater than human input - at least so far.
We need unadulterated data which can show just what human contribution of "pollutants" IS and what that input may cause - whether it may cause actual change as compared to "reversal" - which requires a far better understanding of the complex systems which produce "weather" than we have at the present time.
Could we at least be clear in our terminology as we continue ?
