Cruz et al., 2021 (Argentina)
Argentina’s (Tixi Cave) present annual temperature is 13.8°C. It was 3.5°C (17.3°C), 1.7°C (15.5°C), 3°C (16.8°C), and 4.5°C (18.3°C) warmer than today 3496, 1656, 656, and 160 years before present, respectively. So ~1860 was 4.5°C warmer.

Glasgow, Scotland (CNN)After 11 days of climate talks that have included progress on protecting forests, phasing out coal and transitioning to electric cars, the future of our planet has boiled down to one key thing: who’s going to pay for the mess we’re in?
On Thursday afternoon, the eve of the final day of COP26, huge gaps remain between what different countries want on key issues, including how ambitious the world should be in slashing greenhouse gas emissions, all part of what climate folks call “mitigation.”In what has been the fiercest opposition to the summit’s draft agreement published Wednesday, Bolivia’s chief negotiator Diego Pacheco said his country and 21 other allied nations — including major emitters like China, India and Saudi Arabia — would oppose the entire section on climate change mitigation.

Antarctica sets a record cold six month period…Neumayer station sets new winter record low, sees rapid cooling since 2000!
German Die kalte Sonne here features Antarctica’s record cold winter – the coldest since temperature measurements began some 60 years ago.
Coldest April-September period
The Amundsen Scott station at the South Pole recorded a mean temperature of -60.9°C for the April 1 to September 30 period, according to the US National Snow and Ice Data Center (NSIDC). For the June-July-August period, the mean was minus 62.9°C — the second coldest recorded.
…
Apparently the 140 or so ppm added CO2 couldn’t trap enough heat to prevent a record cold from being set. The previous record for June-July-August was set in 2004.
Neumayer sets record cold, sees 3°C of cooling since 1985
Die kalte Sonne reports that a record was also set at the German Neumayer Antarctic station, located on the Antarctic coast, which saw a mean June-July-August temperature of -28.6°C.

A friend recently suggested that “melting glaciers” must surely prove “global warming is true”.
It is a common belief. After all, glaciers are a visible phenomenon and it all sounds logical.
As you know, I have written extensively about glaciers, (see the “glaciers” tab on the sidebar). But it is worth posting this potted history of them:
…
…
Summary
The modern day retreat of glaciers is part of a much longer natural cycle. Indeed, we find evidence of that cycle going back long before the Middle Ages.
Lamb, for instance, claims that glaciers in the Alps and Norway were advancing between 800 and 400BC, reaching an extent almost as great as during the Little Ice Age. They advanced again around AD600 to a similar position as before.
In between times, of course, the same glaciers also retreated, both during the Roman Warm Period and the Medieval Warming Period.
Whether man-made warming has played any part in modern glacial retreat, we know that:
- Most of the retreat since the 18thC occurred before any possible impact from humans.
- Glaciers were smaller than now in the Middle Ages
- There is nothing unprecedented or alarming about the current state of the world’s glaciers
All of this is common knowledge amongst glaciologists. But for some reason the world of climate science does not want the public to know.

Minerals are essential components in many of today’s rapidly growing clean energy technologies – from wind turbines and electricity networks to electric vehicles. Demand for these minerals will grow quickly as clean energy transitions gather pace. This new World Energy Outlook Special Report provides the most comprehensive analysis to date of the complex links between these minerals and the prospects for a secure, rapid transformation of the energy sector.
Alongside a wealth of detail on mineral demand prospects under different technology and policy assumptions, it examines whether today’s mineral investments can meet the needs of a swiftly changing energy sector. It considers the task ahead to promote responsible and sustainable development of mineral resources, and offers vital insights for policy makers, including six key IEA recommendations for a new, comprehensive approach to mineral security.https://www.iea.org/reports/the-role-of-critical-minerals-in-clean-energy-transitions
The salient points follow:
