Wow, that’s cherry picking data to the extreme. Why have they picked those 3 warm periods when there were 2 much closer to us than the Minoan Warm Period. The Medieval Warm period as well as the late Roman warm period both happened during the last 2000 years. CO2 levels during those periods were about as they were before the onset of the Industrial age about 250 years ago. So what caused those periods. Let’s not forget that during the Roman Warm period wine grew at York in the UK. Try that today. CO2 cannot have been the culprit. Riddle me that. We don’t need to go back to the Pliocene or Millions of years back. After the Medieval Warm Period (MWP) (about 950 to 1250 CE) humanity was hit by a Little Ice Age (LIA) that ended around the end of the 19th century. No drop in CO2 from the MWP to the LIA. How did that happen. And then warming again with the beginning of the 20th century which they like to explain through CO2 rise. So, how about all the other warm and cold periods with no change in CO2 then? Those researchers are selling snake oil and they know it when they leave those facts out knowingly.
A recently released study brought sobering news about the future effects of climate change, predicting they could be twice as bad as current models have projected under a “business-as-usual” scenario — and then some.
