Medieval Climate Optimum by Michael E. Mann, 2002.

If you look at the article you are referring to. Mann's 'hockey stick' paper, You can see the error bars that existed.

The sites you get your information from, that being blogs and such, seem to constantly leave this little set of data out. The paper also provides you with the methods and calibration used. Below is a paper a year later from Mann with the same graphic.

In 2003 Mann published the following paper. Figure 2 shows a definite Medieval Climate Anomaly followed by the Little Ice Age.

Figure 3 here shows quite a few reconstructions showing the two periods.

Finally here Mann has a paper directly concerning these two periods from 2009.

The Lamb graph, which was posted by Kano and which was commented on by graphicconception, comes from a graph originally from Lamb, 1965. or at least the data does.

The graph above, figure 3, stops in about 1950. The temperature reconstruction is from central England, a period that is well known to have been affected by the MWP. Was the MWP global? To some extent. Was it as warm as proxies from central England make it out to be? Current evidence indicate it was not. The warmth in central England during this time period was due to ocean oscillations being in a persistently positive or negative mode. You can see the differences between the two if you look at Lambs paper and Mann's 2009 paper.
And the graphic graphicconception continuously posts stops 95 years before the GISP2 Ice Core was extracted, which occurred in 1993.
Here is a paper from Richard Alley on GISP2 ice core data: ftp://mtarchive.geol.iastate.edu/data/20...
And here is a paper from 2011 regarding a 4000 year isotope temperature reconstruction:
ftp://ftp.ncdc.noaa.gov/pub/data/paleo/i...
"Therefore, we conclude that the current decadal mean temperature in Greenland has not exceeded the envelope of natural variability over the past 4000 years, a period that seems to include part of the Holocene Thermal Maximum. Notwithstanding this conclusion, climate models project that if anthropogenic greenhouse gas emissions continue, the Greenland temperature would exceed the natural variability of the past 4000 years sometime before the year 2100"
Here is a paper on Greenland instrumental temperature records for the period 1873-2001:

Damn, the AC is out.
Sure wish there was some of that global cooling that deniers keep talking about coming my way. :(
90+ in the house.
I can probably put the griddle in the sun for a bit, then put my eggs on it for a couple minutes.
To address the question, no, we didn't forget.
We do know about the medieval warm period.
We do know about that article in Time magazine.
And we also know that, while there was some speculation, there was surely no consensus about cooling.
That's very different than today, when there is widespread consensus.
OK, so if we look at all the "warm periods" in the recent past, if these were not global where were the corresponding cold periods?
Was there a Medieval Warm Period? Lamb said yes, Mann says not.
My partner and i highly recommend applying http://www.vpnmaster.org to unblock internet sites. I am using their services for more than 4 years with no complications.

No they didn't forget. Half of them never knew it since their communist professors never told them. The other half just ignores facts.
Life magazine of January 30, 1970, stated: “Scientists have solid experimental and theoretical evidence to support . . . predictions” such as: “In a decade, urban dwellers will have to wear gas masks to survive air pollution,” and “increased carbon dioxide in the atmosphere will affect earth’s temperature, leading to mass flooding or a new ice age.”
NOTICE: The culprit for going into the Ice Age was CO2. I know many yokels out there will pooh-pooh the idea stating that this was never the 'consensus' thought. However, one only has to look at the writings of H. H. Lamb to disprove this. Jimmy Hansen worked in collaboration with Lamb in his programming his climate models to show this Earth dooming ice age. (He denies it now. He was just following orders.) Of course, Jimmy is now a full time communist activist, so we know which leanings prompted his political shift.
Quote by Chris Folland of UK Meteorological Office: “The data don't matter. We're not basing our recommendations [for reductions in carbon dioxide emissions] upon the data. We're basing them upon the climate models.”
So you can clearly see, the greenies have there own agenda and that facts are just an obstacle.
I was not even aware of it, in the 70's I was too busy chasing women to take notice of climate news.
You mean this graph that the IPCC showed that it was much warmer in the medieval period than now

No, we didn't forget. Unfortunately, there's much, much, *much* more data that conclusively shows that climate change is real.
Nobody wants climate change to be real, it's a huge, scary, looming, potentially disastrous threat. There comes a time, though, when you have to stop wishful thinking and take steps to avert a catastrophe.
O_o I'm hot
No they just want everyone else to. Just like they try to pretend "extreme weather" is something new.
Did "warmers" really forget the global cooling scare of the 1970s or the "Medieval Warm Period" diagram in the 1990 IPCC report?
still hot!
