poor JM. Just can't help himself.

The clown found (directed by WUWT or AllTricksZone) a 1977 paper by some scientist there.

Of course, Clean Air Acts in 1979 got rid of a lot of sulphate emissions from industry so CO2 caused warming started again.

Yes, we had the MWP then the LIA now we have warmed way past the MWP so tree lines have moved north, grape vines in the UK are now well north of where they were in the R[oman]WP etc.

Soo poor lees’ paper is not worth a pinch of pelican poop.

The paper actually talks about trees above the tree line in 1977. And they have tree stumps still there above the tree line. Such a hopeless dick. Grin

"The palynological records of arctic tree-lines in North America give clear evidence of large scale northward displacement of the forest limit during the early Holocene. "

As the terrain grew more hilly, Hakongak’s hopes of spotting caribou rose—the animals were known to run through the area they call Amagalik. Then, as the hunters’ path dipped into marshy lowlands, Hakongak spied what he first thought was a cylindrical rock sticking out of the bog. “I did a quick U-turn and said ‘This is a tree stump!’” the 56-year-old recalls. “My first thought was ‘Wow, this is quite the strange find.’ '

Located on Victoria Island, Cambridge Bay is roughly [url]600 km above the treeline[/url], the latitudes above which the climate is too cold for trees to survive.

Poor JM still can't help himself. Even a 2019 paper shows that the temperature is still less than the MWP. It doesn't matter if the treeline is moving north. It still hasn't got where the treeline for the MWP was.

Lamb's reconstruction that figured in FAR (First Assessment Report) from the IPCC. (chapter 7, Figure 7.1.c) Of course then we had JM's very Mannian mentor. But his has gone by the wayside.

The MWP was arguably warmer than today. Despite his protestations. Wink

The majority of this planet's history has been much much warmer as an overall average through the millions of years.

Yes, the treeline is not as far north as it was in the MWP—trees don’t spring up overnight!

You would think 50 years of AGW would have done it. I mean his comment was "warmed way past the MWP".

https://en.wikipedia.org/wiki/Medieval_Warm_Period

Medieval Warm Period - MWP

The Medieval Warm Period (MWP), also known as the Medieval Climate Optimum or the Medieval Climatic Anomaly, was a time of warm climate in the North Atlantic region that lasted from c. 950 to c. 1250.[2] Climate proxy records show peak warmth occurred at different times for different regions, which indicate that the MWP was not a globally uniform event.[3] Some refer to the MWP as the Medieval Climatic Anomaly to emphasize that climatic effects other than temperature were also important.[4][5]

The MWP was followed by a regionally cooler period in the North Atlantic and elsewhere, which is sometimes called the Little Ice Age (LIA).

Possible causes of the MWP include increased solar activity, decreased volcanic activity, and changes in ocean circulation.[6] Modelling evidence has shown that natural variability is insufficient on its own to explain the MWP and that an external forcing had to be one of the causes.

Poor JM. Has a go at me for a 2019 paper and unearths one from 2013. Grin

And then Milankovitch cycles. According to JM if it isn't Milankovitch cycles it is nothing.
And Marcott 2013? He was the one who said that the recent warming showing on his graph was not "statistically robust"

"Thus, the 20th century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions."

Shaun Marcott from his interview - https://www.realclimate.org/index.php/archives/2013/03/response-by-marcott-et-al...

JM Again.

Jovial Monk wrote on Apr 4^th, 2024 at 7:10am:

This is what I thought was meant—the instrumental record of 20th century and early 21st century warming is incontrovertible.

And it is not necessarily any or all AGW. Roll Eyes

Just think UK Met nearly 8 out of 10 stations in the junk class (Class 4 and Class 5).

Australia's ACORN SAT has also been found to be out of whack and can't be relied on.

The same applies to the US ClimDiv Station data.

USCRN stations are sited away from UHI and other incompatible sources. NOAA uses ClimDiv. Who knew? Roll Eyes
