Undisputed temperature reconstructions from around the world show the planet was much warmer over most of the Holocene (past 10,000 years) than it is today.
Kenneth recently wrote how a wealth of new research in glacier and sea ice extent show modern Iceland is 2-4°C colder than all of the last 8000 years. Only the late 19th century was slightly colder.
That post was featured at WUWT, and a reader there presented other graphs from other parts of the world suggesting the early Holocene was warmer worldwide.
First, South America going back 100 years, which shows it was much warmer from the 1930s to the 1950s than it is today:
Next we have a temperature reconstruction from the Canadian Arctic going back 7000 years:
Note, as many of us have already known, the Arctic was indeed much warmer earlier in the Holocene than it is today.
Finally we look at the Swiss Alps going back 9000 years:
Here we see that the Alps are very cold today compared to the early Holocene. This has also been confirmed by old tree trunks found under glaciers.
The reader at WUWT added he has “a lot more of these types of graphs that show very clearly that the WHOLE WORLD has been much warmer than now for MOST of the last 10,000 years.”
And indeed there are many!
Medieval Warm Period confirmed by hundreds of papers
Dr. Sebastian Lüning’s admirable and outstanding reference Medieval Warm Period Map here shows hundreds climate reconstructions for that period. There we find an abundant number of studies showing today’s climate is nothing unusual compared to 1000 years ago.
Here you will find 80 charts from 58 peer-reviewed papers showing the same.
This massive data record these papers represent is not going to go away.

I’ve likely posted this before, but in case there is a new reader:
Start quote — found on deceased John Daly site:
“It will without doubt have come to your Lordship’s knowledge that a considerable change of climate, inexplicable at present to us, must have taken place in the Circumpolar Regions, by which the severity of the cold that has for centuries past enclosed the seas in the high northern latitudes in an impenetrable barrier of ice has been during the last two years, greatly abated.
(This) affords ample proof that new sources of warmth have been opened and give us leave to hope that the Arctic Seas may at this time be more accessible than they have been for centuries past, and that discoveries may now be made in them not only interesting to the advancement of science but also to the future intercourse of mankind and the commerce of distant nations.”

That is a MAJOR point. For at least 5-8k years this planet has been cooling. On a cold planet life will struggle to survive, on a warm planet, say 2°C to 3°C warmer, life flourishes. So it would be GOOD to have about 1.5°C to 2°C of warming — life would flourish.
Human’s do NOT govern the climate! The egoistical fantasy that we do is just that — a fantasy.
CO2 does not dictate the Earth’s atmospheric temperature, or how it varies — CO2 levels tend to lag (are AFTER) temperature variations.
Climate and it’s many cycles govern how global temperatures vary.
Current long term trend is still a cooling trend NOT warming one.
“Dozens Of Scientists Reveal Most Of The Planet Is COLDER TODAY Than Most Of Past 8000 Years”. Better though: “Dozens of scientists just note most of the planet is colder today” Because scientists are just following the facts.

Gotta love the graph for the Canadian Arctic – the FIRST graph I have ever seen that shows time going backwards!
‘Thousand years before present’ on the horizontal axis, and it starts with zero on the left!
WHY? Are you trying to help the enemy?
Not uncommon for charts in scientific journals relating to geology and paleoclimatology to label their axes that way. Look at other journal publications and you’ll find this.
