Confusing report from Environmentalists

A new report (or should I say a repackaged report?) from environmentalists (I won't call them scientists) states;
WASHINGTON (Reuters) - The last few decades were the warmest on Earth in the past 400 years, and may well have been warmer than any comparable period since the Middle Ages, U.S. scientists reported on Thursday.

Gee, like we didn't know that at times it has been both colder and warmer than it is today. But later the message gets more confusing.

First they have to restate the facts (actually their opinion)

The scientists also noted that temperature reconstructions for periods before the Industrial Revolution -- when levels of climate-warming greenhouse gases were much lower -- supported the notion the current global climate change was caused by human activities, rather than natural variations in climate.

But this guy actually comes out an tells the truth (emphasis is mine).

"Natural climate variability is something that we'd like to know about," said Kurt Cuffey of the University of California-Berkeley, who served on the council's committee and spoke at a Webcast about the report.

"But if we did know for example that the climate was as warm at 1000 AD as it is now, it would have no essential impact on our understanding of climate change in the 20th century, the role of humans in causing it and the need to think seriously about how that may evolve in the next few centuries," he said.

So no matter if the evidence says that it has been warmer at times in the past before the Industrial age it won't change their understanding (read opinion)!
