Sentences with phrase «similar warm period»

I have a similar attitude to other Team studies purporting to show that the modern warm period is warmer than the MWP — I don't think that they've proved this using their data and methods, each study having slightly different problems, but the high degree of linkage between Team studies in terms of proxy selection means that a couple of problem proxies (e.g. bristlecones) can affect a lot of studies that are advertised as «independent».

I've got eight other graphs on the DeSmog Blog, none of which has been questioned in the least, all showing a hockey stick shape in the temperature from 1,000 years ago to today, and all of them showing a pretty similar — the idea that there was a Medieval Warming Period during which the temperature was higher than it is now is, that is like, flagrantly incorrect is the nicest way that I can say it.
