Det bliver måske koldere

Lüning starts by reminding the listeners that geology is key to understanding the past, which in turn can help us to better understand the present and provide valuable clues of what to expect in the future.

The German geologist is a specialist in the geology of Africa. The scientitific literature shows that the Sahara was green a mere 6000 years ago, and his slide at the 0:45 mark show remnants of that time.

Remnants of a green Sahara, 6000 years ago.

Back then, in the mid Holocene, it was 1 – 2°C warmer than it is today and the Sahara was teeming with wildlife.

At the 2:20 mark Lüning shows a slide of cave painting, in the middle of the Sahara, depicting wildlife seen at the time:

Cave paintings of wildlife in the middle of the Sahara.

The changes over the Holocener period clearly are greater than what we are seeing today and are due to natural flcutucations, primarily solar activity. Lüning adds at the 3:40 mark:

This is a geological context that unfortunately is lost on many people like physicists who believe their formulae more than they believe the true facts.”

Greenland is cooling

At the 4:10 mark Lüning brings up the Axforf paper of 2013, which shows Greenland was “2 – 3°C warmer 6000 to 4000 years ago than it is today” and that the ice survived.

At the 5:00 mark he presents a 2013 paper by Lecavalier et al showing that Greenland has cooled 2.5°C over the last 8000 years.

Greenland has cooled 2.5°C over the last 8000 years.

On his slide Lüning writes:

Despite the thousands of years of continuous warmth, the dramatic ice collapse never occurred.”

At the 6:00 mark Lüning shows a chart from Bob Carter, also showing nothing unusual is happening, Co2 playing only a minor role.

At the 7:30 mark Lüning brings up the IPCC 1990 millennium temperature chart that distinctly shows a warmer Medieval Warm Period and a little ice age. At the 8:30 various hockey sticks are shown, which Lüning describes as “incorrect”. “Even Michael Mann had to admit that he had exaggerated”.
