Once again, more dire warnings about our upcoming energy shortage. Indeed, from this site:
http://web.mac.com/sinfonia1/Global_Warming_Politics/A_Hot_Topic_Blog/Entries/2008/10/2_The_Energy_Crunch_Cometh.html
"The blackouts could begin as early as the week commencing November 10, for which the National Grid has warned “that the margin of spare capacity could be as slim as 0.8 gigawatts - the equivalent of one mid-sized coal-fired power station or the electricity consumed by a city the size of Nottingham.”
Will our government, or the"government in waiting" please make this issue a top priority?
FFS, why the dithering?

Hi Nickbat. Now I know from your previous threads that you think that global warming is a myth.
But did you see the recent documentary that stated that in the past temperatures had risen by 5 degrees in one year (according to the ice cores ) and they think that this could happen again at any time with monumental consequencies.
I would be interested to hear your views on this..fact or fiction ?

I watched this programme as well Optimist and noted what the scientists had concluded which was very interesting to say the least. I also understand that the scientists involved in this research have established, using the evidence obtained from the ice core, that the 5 degree climate change happened within days and quote "within no more than a week"
rather than the year you mentioned.
It highlighted what other scientists have predicted could happen very quickly if sea currents, for us in the UK the Gulf Stream, were affected by rising temperatures and diverted further South. The onslaught of fresh water in large volumes from the melting Artic with rapidly reducing salinity of the Atlantic could produce an ice age for the Northern hemisphere, and not for the first time by far. 
It strikes me that whatever man does for the good or worse will be greatly overwhelmed by nature herself as has happened countless times over the history of this planet.
Blackouts could be the least of our problems, and I lived through the blackouts of the early 1970s. 
Oh Lizzie, Lizzie. It's impossible to determine a week within an ice core. Secondly, we are talking about global average temperatures. On a local level, temperatures regularly change by more than 5 degrees in a week. As I noted before, the Arctic melted more in the 1920-1930 period than in the 1995-2005 period...and no one really noticed. Of course, the other thing that the alarmists go on about is rising sea levels due to melting ice caps. Remember that (aside from the fact that Antarctica is growing in size) the melting of sea ice cannot have an effect on sea levels (due to the relative displacement of the ice). It could only have an effect if ice on land melted and thus added to the total ocean volume.
The other thing to remember is that global temperatures are roughly back to where they were a hundred years ago (I say roughly because we are talking about fractions of a degree here - something which they couldn't measure years ago anyway).
The whole idea is to scare people and, in that way they are doing a pretty good job. In contrast, the upcoming energy shortage is entirely man-made (and avoidable, which climate change isn't) and is very scary. 
I take your overall point, and those in the post of yours following this Nick

.
Of course it is all opinions of individual scientist and their interuptation of the evidence in front of them, as in the field I study, History, where 12 historians can come up with 13 conclusions!!
However the ice core in question went from opaque to clear, interupted by regular bands of snow. I am NO scientist that's for sure

, but the scientist who was being interviewed explained that there had been a
sudden rise of 5 degrees "within days" that was
dramatic and "permanent", completely out of line with any 'normal' regular changes in the climate. This was in the Iceland area where such temperature fluctations would not have been expected, as confirmed by the ice core's "record" of weather over thousands of years.

Like everyone else I suppose all we can do is be spectators to the 'experts' conclusions of the evidence, and of course
always question when we can, but the evidence in this case was compelling.
So who really knows Nick? I don't think anyone really does yet as nature, history, time and space seem to hold their secrets extremely well!
