Americans sweltering in the recent record-breaking heatwave may not believe it - but it seems that our ancestors suffered through much hotter summers in times gone by, several of them within the last 2,000 years.


Phew, what a scorcher, Marcus. Let's get in the frigidarium

A new study measuring temperatures over the past two millennia has concluded that in fact the temperatures seen in the last decade are far from being the hottest in history.

A large team of scientists making a comprehensive study of data from tree rings say that in fact global temperatures have been on a falling trend for the past 2,000 years and they have often been noticeably higher than they are today - despite the absence of any significant amounts of human-released carbon dioxide in the atmosphere back then.

"We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low," says Professor-Doktor Jan Esper of the Johannes Gutenberg-Universität Mainz, one of the scientists leading the study. "Such findings are also significant with regard to climate policy."

They certainly are, as it is a central plank of climate policy worldwide that the current temperatures are the highest ever seen for many millennia, and that this results from rising levels of atmospheric CO2emitted by human activities such as industry, transport etc.

If it is the case that actually the climate has often been warmer without any significant CO2 emissions having taken place - suggesting that CO2 emissions simply aren't that important - the case for huge efforts to cut those emissions largely disappears.

Around the time of Robin Hood in England in the middle ages, it was warmer there. Warm enough that the English grew grapes for making wine. Then it turned colder and they were left with barley for beer and whiskey......

They also had to change the architecture of their houses to keep them warm in the colder winters.
