Conclusion: Global warming IS occurring. Many years it’s negative warming.
They will this group of scientists more funding.
That grifter prick should be in jail, sharing a cell with the klintoons, obama and the rest of the thieves.
I have no problem with using tree rings as a proxy for temperature trends. My objection to using them as definitive evidence of exact temperatures stems from what you pointed out, that other factors besides temperature affect tree growth. There is absolutely no way to derive a temperature to within 1/100 of a degree by using tree rings.
If you want a historical record, you need to either use the same measurement modality across the time period under study, or you need to validate that a new modality is functionally equivalent to an old one. I doubt that it is possible to validate the use of tree rings vs. thermometers as being equivalent modalities.
I think that the most accurate methods of taking measurements involve satellites, since they can look at an area and come up with a temperature based on the average pixel temperature. That method smooths out the hot spots that are problematic for trying to place ground thermometers.
If all a scientist is doing is trying to get an idea of the climate over the last 1,000 years, then tree rings are perfectly adequate for the job. But trying to fear-monger about how the earth is 1 degree hotter than 1,000 years ago, ergo anthropogenic global warming, is not supported by the evidence.

You’re all going to die from ‘climate wiggles’ — CLIMATE WIGGLES !!!!???
Not me, I am going to die from LMAO at these loons.

The “climate change” leftists really blew it a couple months ago, when a U.N. official with the IPCC (climate change summit) blurted out “ The REAL goal of ours is to destroy capitalism”
