Good bit warmer than now. We can tell because in Greenland receding glaciers are exposing Viking settlements, where beech tree stumps can be found in permafrost.

Can you provide a reference for "receding glaciers ... exposing Viking settlements"? All the historical documentation of Vikings referred only two Greenland settlements -- the Eastern ad Western settlements. You can look at Googlemaps images of the sites for the Western and Eastern Settlements:
 
  Eastern settlement area, and Eastern settlement map
  Western settlement area, and Western settlement map.
 
Just for reference, here is a zoom of the area of the Brattahlid and Gardar farms (two of the largest/richest farms), and a zoom of the Sandnes farm area from the Western settlement.

Want more? How about on the ground photos of the ruins?

They are a long way from receding glaciers, and quite green in summer. So again, at least some reference for these newly discovered Viking settlements that were underneath glaciers would be appreciated, because otherwise I'll just have to assume you are making shit up.

There seems to be some viking farms being uncovered in Greenland. Yup, the glaciers are melting and in the process exposing abandoned farms. Hmm. Seems to me that if there were farms where there's currently glaciers, that would imply it being much warmer in the past.

Do you actually have a cite for this, because it would be significant news to me -- not the fact that there were Norse farms in Greenland, but that there are Norse farms that are only now being uncovered by retreating glaciers. You see, as far as I know (and I've had an ongoing interest in the Norse settlements in Greenland) all the settlements that were ever mentioned in historical records have been accounted for -- the Eastern and Western settlements. For some time no-one quite believed in the Eastern settlement, until they eventually found it, not quite where people were expecting. So, two settlements known from records, two settlements found. Are either of those settlements under ice? It seems Google maps and satellite photos can come to out aid. Consider these Googlemaps images of the sites for the Western and Eastern Settlements:

  Eastern settlement area, and Eastern settlment map
  Western settlement area, and Western settlement map.

Obviously not "under ice", but rather sitting in what are nice green pastures (the benefits of being situated in fjords). So can you tell me where the newly discovered settlements that are being revealed by retreating glaciers are to be found?

That is propaganda and was completely ridiculous when the first 'scientist' thought it up. It's about as smart as the 'Greenland isn't really green' argument. We all know that, but there are settlements that are still under ice that weren't during the MWP.

Really? You wouldn't happend to have any reference at all for that would you? The settlements under ice that is ... there were Norse settlements on Greenland, and the historical records spoke of an Eastern and a Western settlement.

Obviously not "under ice", but rather sitting in what are nice green pastures (the benefits of being situated in fjords). So, the question remains -- what of these mysterious settlements that are still "under ice"? How do we know they're there? Certainly no historical records of any kind mention anything other than the Eastern and Western settlements, which as we saw are clearly far from "under ice". No one has found settlements under ice that I'm aware of. So please ... enlighten me, I want to know about these under ice settlements.

We don't have records about ships making it through then, but it was warmer then than it is now in the more northern and arctic regions and we know for a fact that the vikings had habitable settlements where it is all frozen ice now and you can't grow anything

Your statement about the Norse settlements in Greenland is patently false (unless by "now" you mean "February - March" as opposed to "this century"). The locations of the Norse settlements are known. Google maps and satellite photos can come to out aid. in determining how ice covered they are:

Just saying it looks like a vast ice sheet from where I'm sitting

That depends on where you look -- if you look where the Norse settlements were...

Eastern settlment area, and Eastern settlment map

Gardar ruins; Bratthlid ruins; Hvalsey church ... You'll find it's fairly green.

Is Greenland green yet or is it still covered in ice? If Vikings farmed there then, doesn't that mean the world was much much warmer than today?

So yes, Greenland was green with regard to where the Vikings settled, but then it has been the whole time, and still is today.

Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures.

You may have an interesting definition of significant change. The satellite data for temperatures shows an increase that is quite notable.

Average ground station readings do show a mild warming of 0.6 to 0.8C over the last 100 years, which is well within the natural variations recorded in the last millennium.

Most reconstructions of temperatures over the last millenium (and that includes many more than those offered by Mann and Bradley) show that the current observed warming is significant in terms of the rate at which it has occurred. Indeed, most show the current warming over the last 100 years as outside the range of reconstructed temperatures over the last millenium.

The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands"), which show substantially higher readings than adjacent rural areas ("land use effects").

Of course the land based records attempt to take such effects into account, but aside from that we also have the ocean temperature records (which agree closely with the land based records), and several studies which all conclude that UHI effects don't cause the warming observed: [Parker 2004], [Parker 2006], [Peterson 2003]. Not to mention that if we go back to the question of satellite temperatures we see that they show no significant difference in trend to land based observations.

Significant changes in climate have continually occurred throughout geologic time. For instance, the Medieval Warm Period, from around 1000 to1200 AD (when the Vikings farmed on Greenland) was followed by a period known as the Little Ice Age

Mention of the Vikings on Greenland wrt the medieval warm period being very warm is deceptive. If you actually look at where the viking settlements were (Eastern Settlement, Western Settlement), and then check satellite imagery of those areas (Eastern Settlement, Western Settlement), you'll see that they are in sheltered fjords that are naturally quite green and suitable for farming. Some photos of the Viking ruins will confirm this (eg. this, or this).

The "hockey stick", a poster boy of both the UN's IPCC and Canada's Environment Department, ignores historical recorded climatic swings, and has now also been proven to be flawed and statistically unreliable as well. It is a computer construct and a faulty one at that.

Of course, as noted earlier, the Mann, Bradley, Hughes temperature reconstruction of 1998 is far from the only such effort. The others produced qualitatively similar results. Further, while there has been dispute of the original 1998 piece, the National Academy of Science report on the subject concluded tha
