[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]The climate is always changing and on a much longer time scale than humans have been around to impact.  Educate yourself on the Milankovitch cycles - https://climate.nasa.gov/news/2948/milankovitch-orbital-cycles-and-their-role-in-earths-climate/#:~:text=These%20cyclical%20orbital%20movements%2C%20which,and%20south%20of%20the%20equator)

You heard it here first summer 2023 temperatures for most if not all of the US will be the lowest on record. [/quote]
I think it’s so adorable that conservatives always think it’s some ground breaking news that the earth’s climate has AlWaYs ChAnGeD. It wasn’t habitable by humans for much of that time.

And for you, dear sweet summer child. It’s just a cartoon so perhaps you’ll grasp its implications: [b]https://xkcd.com/1732/[/b][/quote]

This is really well done. Thank you, PP.[/quote]

Can a conservative comment on this? [/quote]

I'll bite.  The first thing that struck me is the smoothing.  They are operating on larger time scales in the early part, so any jumps will be averaged out more, while recent temperatures with the solid black line is better known.  They notes say they are using Shakun and Marcott.  I don't recognize Shakun, but I remember there was a lot of objection to the methods used by Marcott at the time of publication.  Search site:climateaudit.org Marcott and Shakun's name comes up in the results.  You can look at that if you want to review more technical details.  However, generally I think you get similar results in almost every reconstruction, but a little wavier with certain parts approaching modern temperatures, instead of a smooth growth.
People argue the Holocene was either a warmer time period or about the same temperature as now, as well as some other time periods, that are erased in this cartoon.

It says Medieval Warm Period was regional and not enough to affect global temperatures.  This is disputed, and there is evidence of this warm period in many places.  
There is rumors of an e-mail went out among IPCC from I think Jonathan Overpeck,'We have to erase the Medieval Warm Period.'  There was a chart of global temperatures that appeared in an earlier IPCC report by Lamb that was inconvenient for the narrative, leading people to the conclusion that maybe this is just natural warming.
A counterargument that is used, is that if it were warmer in Medieval Times, that just makes global warming more of a problem, as it means temperatures are even more sensitive to forcing changes than scientists generally conclude.

Another detail is that most of the warming shown at the end is predicted, not actual.  It has been 7 years since that chart, so maybe there would be a little more, but three or four of those color blocks would not appear on the actual temperature line.[/quote]

Climateaudit just looks like a rehash of the bogus Tony Watts pseudoscience climate denial mumbo jumbo IMHO.[/quote]
