You seem to be missing the point here. The principal cause of the HTM was Milankovitch forcing. To be correct, the HTM is the lagged response to peak Milankovitch forcing. It is the warmest period of climate variation since the termination of the last glacial ca 12kya.
You ask if the current warming is different to previous episodes and the answer is yes - it's getting warm enough to melt ice that formed 5kya as the post-HTM cooling got under way.
The HTM ended because the energy from the orbital forcing eventually dissipated from the oceans into space. The CO2-forced present warming will not fade in the same way because anthropogenic CO2 is additional to the natural carbon cycle and takes many centuries to begin to become integrated into it and absorbed by natural sinks.
So, the current warming is profoundly unusual. There is no natural physical mechanism that will stop it quickly. The extent of the warming will be determined by the equilibrium climate sensitivity and the amount of CO2 in the atmosphere.
This, if fully understood, is ample cause for concern.

According to the Guardian, the Obama administration is turning in the poor man who discovered the drowning polar bears so they can discredit his research and so open up Alaska for oil exploration.
Who'd a thunk it?

So we're heading back towards the Holocene Thermal Maximum -- mebbe. It was, if my reading is correct, "up to" 3C warmer than today. The graphs I've been able to find suggest temperatures not very different from today. I have not read anything to suggest that this was in any way catastrophic and it seems that the temperature increase was greater towards high latitudes as is projected for the current warming.
So my immediate reaction is: "Bring it on".
Considering that the Holocene Maximum didn't last and that according to Lemonick, scientists "know that greenhouse gases are implicated in episodes of climate change going back millions of years" there doesn't seem any particular cause for panic.
It's this perennial "this time it's different", which is the undertone of every scare story that only reinforces scepticism.

I too prefer Advisor to Adviser.
What is your position on "vampire power" vis a vis the impending abolition of the standby function on any of the next electronic gizmos you buy after October 2014?
This is order that we "save" 19.8 Mt per year CO2 emissions by 2020.
In its prime, Eggborough Power Station, (2,000 MW - which could be very handy in a couple of years time) would be "belching" out about 12 Mt per year of CO2 emmissions.
On 31 December 2015, under EU decree, the same people who are killing your standby, we shall have lost over 11,000 MW, or about 66 Mt per year of CO2 emmissions.
It is therefore obvious that killing your standby facility, at enormous cost to the peasants, is a useless gesture.
And all because of "global warming causing" carbon dioxide, sorry "carbon".
Oh, btw, they probably have included vibrators (note: NOT vibraters) in the law under the item "Appliances ...massage and other body care appliances".
Only doubles all round for this I think.

Something has annoyed Steve Jones- see last paragraph.

If we leave our mobile phone charger plugged in, it is asserted by unreal scients that we are killing the planet. However, a real scientist in the government whispers that this is myth, and yet apparently, we deserve to be "red buttoned" for consuming such vampire power.
Indeed. It was none other than the chief scientific advisor to DECC, Prof. David MacKay.
Follow the link; there's too much to quote ;-)

Polly Toynbee gets her knickers in a twist about Andrew Turnbull not being 100% convinced by AGW, its all the Tea Parties fault gets into the twisted logic and Steve Jones is a wonderful man

And Moonbat blames the Tea Party on the Koch brothers but never mentions climate change deniers being funded by the Koch's, is this deliberate ?

Ah, yes deadly polluting carbon dioxide, sorry "carbon". What a strange world we live in now.
In 100 years we have gone from open fires and the zinc baths placed in front of them, to Government subsidised "Heat Pumps" and marble lined "Wet Rooms".
From the 1915 Morris Cowley to the 1965 Aston Martin DB5, then fifty years later we get to the, wait for it, the G-Wiz, and unreal scientists are asserting that we are killing the planet by going down in the Mondeo to Tescos for our food.
In the fifty years from 1915 to 1965, engineers together with real scientists took us, in huge technological (sometimes perilous) leaps, from the 115 mph Sopwith Camel to the 2,000 mph Lockheed SR-71 "Blackbird". Then, 50 years later, we arrive at at a point where unreal scientists are asserting that we are killing the planet by scrunching up in a Boeing 737 going to Alicante and back once a year.
If we leave our mobile phone charger plugged in, it is asserted by unreal scients that we are killing the planet. However, a real scientist in the government whispers that this is myth, and yet apparently, we deserve to be "red buttoned" for consuming such vampire power.
This vampire power battle actually has been won by the supporters of unreal scientists in that, last October, not by a vote in the HoC, but by a Statutory Instrument (normally used to permit the legal closure of motorway slip-roads), the very useful standby facility on our electronic goodies is likely to be abolished within two or three years, unless real scientists and engineers can come up with some some circuits and components that fall within this absurd law. This insane law also covers not only your Sky box, but also electric tooth brushes and toy car racing sets, although vibrators were not mentioned as far as I could see.
So this where this carbon dioxide "pollution" argument has got us, and it will only get worse I fear.
We cannot expect an up-rising, for obvious reasons if you cast your eyes around next time you venture out onto the streets.

An excellent, recent history of this episode is A. W. Montford’s The Hockey Stick Illusion.
