Derbyshire fossil study wanders into climate alarm zone

Headline: ‘Derbyshire fossil study reveals insights into Peak District’s 12 million year-old climatic past’. Sounds plausible perhaps. But the article below contains a big blunder, or at least a propaganda trick. The relevant quote: ‘Today Derbyshire has a mean annual temperature of around 8°C with up to 1000mm of rain a year, 12 million years ago it was 12-18°C with 1200-1400mm of rain. This doubling of temperature was with atmospheric carbon dioxide levels similar to those predicted for 2060.’ Doubling? In Kelvin terms the increase is more like 3%, but maybe that wouldn’t sound startling enough. The expressed idea here turns out to be to promote ‘carbon capture’.

A decade-long study into unique rocks near a Derbyshire village has been uncovering the secrets of what the county and the Peak District might have looked like under a much warmer and wetter past, says Northumbria University (via Phys.org).

Although first studied over 10 years ago, the most recent investigation into geological deposits near Brassington was initiated in 2019, with an international team of researchers from Northumbria University, the British Geological Survey, Morehead State University in the U.S. and CONICET in Argentina now assessing their latest findings.

The complex techniques used can analyze the fossil pollen of plants and spores of fungi captured within the rock layer, helping to form a picture of past habitats and reconstruct likely climatic conditions far beyond our most recent understanding of the Peak District.

With plants and fungi generally favoring particular conditions, researchers are able to determine what the environment may have looked like some 12 million years ago.

The results and insights are unique to the study location in Derbyshire, as there are no other rocks of a similar age anywhere else in the UK.

Gaining similar understanding to life and climate in Europe so far back would likely require analysis of rocks from Germany or the Netherlands and then assuming these were the same for Derbyshire and the Peak District.

The results from the Derbyshire site and similar studies have gone on to suggest that the UK may get wetter with climate change. Today Derbyshire has a mean annual temperature of around 8°C with up to 1000mm of rain a year, 12 million years ago it was 12-18°C with 1200-1400mm of rain.

This doubling of temperature was with atmospheric carbon dioxide levels similar to those predicted for 2060. These differences in temperature and rainfall would fundamentally change the entire landscape.

This highlights how important carbon capture is to avoid extreme changes in climate.
