Tree-rings prove climate was WARMER in Roman and Medieval times than it is now - and world has been cooling for 2,000 years

  • Study of semi-fossilised trees gives accurate climate reading back to 138BC
  • World was warmer in Roman and Medieval times than it is now
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.
