How did the Romans grow grapes in northern England? Perhaps because it was warmer than we thought.
A study suggests the Britain of 2,000 years ago experienced a lengthy period of hotter summers than today.
German researchers used data from tree rings – a key indicator of past climate – to claim the world has been on a ‘long-term cooling trend’ for two millennia until the global warming of the twentieth century.
This cooling was punctuated by a couple of warm spells.
These are the Medieval Warm Period, which is well known, but also a period during the toga-wearing Roman times when temperatures were apparently 1 deg C warmer than now.
They say the very warm period during the years 21 to 50AD has been underestimated by climate scientists.
Lead author Professor Dr Jan Esper of Johannes Gutenberg University in Mainz said: ‘We found that previous estimates of historical temperatures during the Roman era and the Middle Ages were too low.
In general the scientists found a slow cooling of 0.6C over 2,000 years, which they attributed to changes in the Earth’s orbit which took it further away from the Sun.
The study is published in Nature Climate Change.
It is based on measurements stretching back to 138BC.

Ping.
Well, this explains a lot about why the Romans built the Appian Way - they needed a paved road for their SUVs!!
That’s why the earth was warmer back then.
The real question should be, how deep will the ice be over Manhattan in the next 20,000 years? It is coming and not all the SUVs on Earth are going to stop it.
Lots of ways. Tree rings, for one. Evidence of wind patterns such as dust and pollen transport, sea levels, species migration, soil deposits - there's actually quite a few factors that together paint a reasonably good picture of climate for thousands or even hundreds of millions of years before now.
However, if you want to know what the wind chill factor was in central Pangaea @ 20E 40N on January 4th, 210,537,896 BC at 9AM in the morning, you're kinda on your own. Science isn't THAT good.
Being able to put down citrus groves and vineyards as far north as the Scottish border was another

Wow some stout looking motors on those rigs....
Not to mention the exhaust fumes from all those chariots.
But but but but it was real hot a couple weeks ago.
