The Version 6.0 global average lower tropospheric temperature (LT) anomaly for May, 2020 was +0.54 deg. C, up from the April, 2020 value of +0.38 deg. C.
The linear warming trend since January, 1979 is +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
Various regional LT departures from the 30-year (1981-2010) average for the last 17 months are:

You said “The MWP was regional, not global”
Your reference is completely wrong. The MWP was global. It was caused by a period of very few volcanic eruptions, which have a global effect.
Conversely, the LIA was caused by increased volcanic activity, and was also global. ALL periods of decreased temperatures in The Central England Temperatures data set, which began in 1650. correlate to the SO2 emissions of a volcanic eruption,
Also at the same time as a GSM which in its self can increase seismic and volcanic activity
“Also at the same time as a GSM which in its self can increase seismic and volcanic activity”
Really – show me the science behind that assertion.
There are 3 types of CRF or GCR ions and muons, muons are the babies that stimulate activity
I did not ask for your assertion. I asked for science.
Ok Jack I’m surprised you did not know about this, remember Jack a minor atmospheric gas has no influence on the climate ,

Plenty more were that came from Jack
OK -show me the plenty more.
B d Clark:
VERY interesting, if true.
Is this your guess, or do you have data or a link to prove it?
Sure Burl you probably already know about the maunder minimum that happened within the time frame,heres a few links on studies =muons

Another use of muons in the study of potential activity

“Here we use global palaeoclimate reconstructions for the past 2,000 years, and find no evidence for preindustrial globally coherent cold and warm epochs. ”

Jack Dale:
Again, your reference is incorrect.
See my analysis of the Central England instrumental temperature data set data set
https://www.Osf.io/b2vxp/
I will see you one data set from one location and raise you 691 data sets from 648 locations.
Jack Dale:
My one data set will trump all of yours.
I’m putting this quote down here because the subthread is way too long.
John Tillman: “But even were the mechanisms not known, the fact remains that recent warming is no different from prior such cycles, thus the null hypothesis can’t be rejected. That means that natural cycles from whatever cause can fully explain observations, even if not understood.”
John Tillman has just summed up the whole Human-caused Climate Change argument: Natural cycles can fully explain observations, even if not understood.
The only way for the Climategate Charlatans to overcome this argument was for them to try to erase history and create a bogus, bastardized global surface temperature chart that doesn’t even come close to representing reality, by making it appear that the past was cooler than the present, when in fact, the past, even the recent past, was just as warm as it is today. The unmodified Tmax charts from around the world prove it. CO2 is not the control knob of the Earth’s climate, Mother Nature is.
Thanks for that insightful quote, John.
How will the alarmists refute this argument? Probably by posting bogus, bastardized modern-era Hockey Stick charts, because that is the only “evidence” they can show. They have to use a fraudulent Hockey Stick chart to try to change history. But we still have the regional Tmax charts to show the Hockey Stick chart is a lie.
For people who don’t know the difference between a bogus Hockey Stick chart and a chart that actually represents the true temperature profile, here is a link to James Hansen’s U.S. surface temperature chart (Hansen 1999) next to a bogus, bastardized, “hotter and hotter” Hockey Stick chart.
https://www.giss.nasa.gov/research/briefs/hansen_07/
As you can see, the U.S. chart shows it was just as warm in the 1930’s as it is today (recall that 1998 and 2016 are tied for the warmest years of the satellite era), where Hansen says 1934 was 0.5C warmer than 1998. The U.S. surface temperature chart also shows the era of cooling from the 1940’s down through the 1970’s.
Now notice that not only did the bogus Hockey Stick chart cool the 1930’s to where they look cooler than the present day, and in the process they also disappeared the cool 1970’s when climate scientists were warning about a coming Ice Age. You wouldn’t even know there was a cool 1970’s by looking at the bogus Hockey Stick chart. The Data Manipulators had to do the chart this way in order to make it appear that temperatures were getting hotter and hotter and hotter every decade and were now at the hottest temperatures in human history.
Except every bit of if is a Big Lie. The unmodified Tmax charts, and charts like Hansen 1999, put the lie to the Hockey Stick charts.
Very chilly on the English south coast, St Leonards to be precise. Very blustery northerly all day. I was working out in the garden and my fingers were numb. Mind you we’ve had record sunshine ever since Covid 19 caused a lock down, but in the strong sunshine its been very pleasant but very cold today
