Current temperature is maybe the hottest in recorded history (which is about 150 years) and that is a big maybe. Its definitely not the hottest in human history

Current temperature is maybe the hottest in recorded history (which is about 150 years) and that is a big maybe. Its definitely not the hottest in human history. Medieval warming period was much warmer than it is now. I would even argue the 1930s were hotter as well.

No, it wasn't. Global aversge temperature is above the peak of anything that might be in the MWP today (the MWP had a really small global effect, with different local warming periods in different regions.) > I would even argue the 1930s were hotter as well. Well, you can argue anything, but finding data to support that argument might be difficult.

  Until about the mid-90s of last century the Medieval Warm Period was for climate researchers an undisputed fact. The IPCC itself reported this as such in their 1990 report and included this graph. https://i1.wp.com/www.science-skeptical.de/wp-content/uploads/2009/11/lambh23.jpg?zoom=2 https://i1.wp.com/www.science-skeptical.de/wp-content/upload... Here is another chart published by IPCC in 1995 it shows both the Medieval warm period and the 1930s as being hotter than it is now. https://stevengoddard.files.wordpress.com/2011/05/screenhunter_78-may-11-10-03.gif https://stevengoddard.files.wordpress.com/2011/05/screenhunt... Since then there has been an effort to erase this data from the record because it contradicts current climate change narrative. None of what Im saying is a theory. These are facts and there are loads of leaked emails and testimony under oath that says as much. https://www.youtube.com/watch?v=u1rj00BoItw https://www.youtube.com/watch?v=u1rj00BoItw Up your research game my friend.

    > Until about the mid-90s of last century the Medieval Warm Period was for climate researchers an undisputed fact. The MWP is, if not undisputed, a widely accepted fact, though of dubious significance; a very slight rise in average global temperatures over a several centuries long period does show up, as, within that long period, do shorter and much more pronounced and non-synchronized regional warm periods. Global average temperatures in the MWP, though, were notably lower than today. > The IPCC itself reported this as such in their 1990 report and included this graph. Maybe, maybe not. Given your misrepresentation on the next one, I'm not taking your word for it, and in any case there is no clear indication of what that is a graph of; it looks a lot like the graph of European temperatures provided in your other link, but with lower resolution and presumably an earlier end date, which of course is immaterial to the discussion of global temperature trends. > Here is another chart published by IPCC in 1995 it shows both the Medieval warm period and the 1930s as being hotter than it is now. Nope, that's a chart published by someone else later that claims to be based on a diagram published by the IPCC which (obviously) doesn't show temperatures today at all (1995 is more than two decades ago, and global warming didn't stop then), and, in any case, doesn't show global temperature at all, either, only European temperature. Regional temperature trends don't always reflect global trends. Yes, Europe experienced notable local warming in the MWP and the early 20th century (and dramatic local cooling in the period sometimes called the “Little Ice Age” which, IIRC, doesn't show up at all in global trends and is at least in part within the global MWP, though the warm regions that brought up the global aversge at the time were elsewhere.) > Since then there has been an effort to erase this data from the record No, the local trends that the charts you point to reflect are widely acknowledged by climate scientists today—they are, however, local, not global. > Up your research game my friend Hey, I'm not the one who offered a chart without reading the caption. Having a good research game is more than just spamming links without understanding the content.
