Roman Warm Period Was 2°C Warmer Than Today, New Study Shows
The Romans were great administrators and bookkeepers. And today we still have many of those records. Some of the most interesting ones are tax records. When Rome returned to tax harvesting, the collectors recorded all kinds of harvest as payment for the tax and this gives us a pretty good picture of what grew where and when. Those records are way more accurate than any proxy measurements using tree rings or rat urine. And I dont think that Roman collectors faked those entries to make fun of 20-century alarmists.
