Arctic Was Much Warmer 6000 Years Ago… 90% Of Glaciers, Ice Caps Smaller Than Present Or Absent!
We have known since before I was born that the Medieval Warm period has on average been warmer than anything we have seen since the start of the 20th century. We also know that the roman Warm period was warmer still. And so it was for Warm periods before. If there is one trend that we can observe its that warm periods between the Cold periods become cooler and shorter. Because we are on our way to a full Ice Age when eventually glaciers will stretch down to New York and Paris. We will wish Global Warming would really work.
Climate alarmists hate this inconvenient fact: hundreds of temperature reconstructions show that the northern hemisphere was much warmer over much of the past 10,000 years (Holocene) than it is today.
