I'd be cagey about being quite so categorical Mr Sleet (turning to rain in the years to come)!
The jury seems to be out on cause and effect. In any case, there is clear science in favour of increased CO2 causing warming, the chemical and physical effects are matters of demonstrated occurrence. It is quite possible that in times gone by there has been warming due to other causes, which has triggered a release of biomass / locked carbon into the atmosphere; this, however, is not to say that in the present time, when man's activities are releasing much more locked carbon (e.g. coal, oil, wood) that would otherwise have cycled much more slowly, a different mechanism is at play. In which case be very afraid, because we should expect a secondary positive feedback downstream consequent to this warming which would heighten the CO2 effect even more.
The one problem with the various ice core analyses is that they never tell us what else was going on at the same time. Just as we know at present, there may be several forcing mechanisms at play, and all we experience is the net effect of complex interplay.
I'm not quite sure what styrange deductive or inductive logic you're arriiving at, by the way, to leap from CO2 lagging temperature to CO2 levels driving ice ages. I think, for this reader at least, you need to elaborate a little.
There speaks one who knows nothing of the wonder of statistical process control!
I know what you mean, but in practice I think that filtering sources for rigour of opinion is helpful. I could step onto the streets of this northern metropolis in which I am located and randomly garner 100 views the majority of which would be so ill informed as to be of no value at all in enabling "considered judgement".
That's why judges sit in court rather than you or I. They have knowledge of the law and legal process. I'm more open to primary material sourced from scientists who specialise in earth sciences, than I am from some tobacco chewing right winger who has set up a web site, titled, say, Anyday soon I won't need a freezer to keep my peas frozen.nutters-org.us
Regardless of the paper, the view was gleaned from scientists - albeit not a detailed report.
As for a judge sitting in court - it is the jury who decide the outcome or fate of the accused, not the judge; he delivers the sentence.

Not the most scrupulous source, and as might be expected not the most accurate representation of a picture that is, in all probability, much more complex than that.
Indeed but to get an accurate picture of any situation, having information from all possible sources is the best way to go about it - that way a considered judgment can then possibly be concluded

I read in the Metro today:
Quote:
10 years to doomsday
Climate change could start to spiral out of control in just ten years, scientists warned yesterday. New data from an ice core drilled out of the Antartic permafrost has revealed major rises in carbon dioxide levels.
The core, stretching through layers dating back 800,000 years, contained tiny bubbles of air which were analysed by the British Antartctic Survey. For most of the time, CO2 levels stayed at between 180 and 200 parts per million of air. Today's levels are 380 parts/million.
Scientists who tested the ice said the rise was caused by burning fossil fuels. They said there was a 'tipping point' of 440 parts/;million when climate change would start t run out of control.
End Quote.

Someone got there before me. It's a terrible terrible plant. It wreaks havoc in watercourses, but also in woodland, hedgerows, scrubland, and wherever the seeds land.
If you pull it out of the ground and drop it, it re-roots and continues growing. If you rip it out of the ground and place it somewhere high, It'll continue growing using its own rotting carcass as a food source.
Worse still, given the harsh climate it originally came from, it can grow virulently just about anywhere.
I have had three of these in my garden - I ripped them out thinking they were weeds, probably did the right thing for once!

Well if you will read 'comics' then that is what you get !!

I thought at first my eyes where playing tricks on me , as i looked closer it looked like a humming bird but it was SO small
i didnt know what to think. Half of it looked like a moth the other a humming bird
I googled it and found
http://www.uksafari.com/hummingbird.htm
Never seen one in this country before
But it looks like it has feathers and eyes! How can it me a moth (I hate moths especially big ones
) -
think of all those poor astrologers...pluto is an infuence in peoples horoscopes
and the Walt Disney film in which Pluto is mentioned and Pluto the dog appears - they will have to change that or not show it again!!
I have to admit that I will still think of it as a planet in any event.
-
I think it is a real shame ...

Thanks Angel I thought it was intresting to.I know what you mean about temps of -83c scarey lol
Tell me about it! You would need thermal thermals!!
beautiful cloud formation though - almost gem-like. -
Another interested subject regarding global warming
1st August 2006
Like brushstrokes rippling across the sky, this iridescent cloud dazzles with the colours of the fading sun.
Photographed over Antarctica, the rare nacreous cloud is made up of millions of ice crystals which bend and scatter the sun’s rays, creating a pastel rainbow.
Also known as mother of pearl clouds, these formations only occur high in the atmosphere, in some of the coldest temperatures on Earth.
But their ethereal beauty may conceal a dark secret - it is thought that chemical reactions on the surface of the clouds help deplete the ozone layer.

That is a very intersting article - imagine temps of -83c!! Incredible!

On the news last night it was brought to light that the water company actually sold off one resevoir in favour of building 150 new homes in the South East! They drained the resevoir just to do that.

London currently 25°C Wind: 2 mph NNE Humidity: 57.4%

Sounds like something out of The Fog! Pity you couldn't get a pic of it.

It's intresting to read about the future predictions, however while summers may well get drier, if winters get wetter then surely if we manage water correctly there is not gonig to any net loss of water through climate change, in other words we'll get just as much rain as before but it'll be more akin to the tropical regions that have a wet and dry season. I think flash flooding will be a massive problem for some areas in the next 50-100 year, I bet London gets flooded badly at least once in the next 100 years.
True - only problem will be if the winters are not wet, it was fairly 'mild' (sorry to use that term!) this winter.

This is from the Met office - seems we are all in for a rough time ahead

Very interesting ... and worrying!

Not sure netting will prevent it - might even be a hazard for birds or squirrels getting caught up in it to be honest. But see how it goes - if it works, you could patent it!
appears not to be a hazard to them, even the young birds simply perch on top, Ive never seen one that was in trouble from it.

Excellent - I hate to see birds injured - had one casualty this year - a fledgling - one of my cats brought her in and she was cheeping loudly (and I mean at full volume) in the hall at about 2am in the morning - so I got up and picked her up (she was unharmed) and rang our local bird lady the next day who works for RSPCA and she told me to feed her with cat food until we could get the bird to her - which we did. She was amazing!! Every two hours we would feed her a wee bit of food and she would flutter her wings and really bawl for it! If I didn't have cats, I would have an avery in the garden and take in sick or injured birds myself. Anywa, glad it works

That is journalists for you - scaremongering I think is the name of their game, or sensationalising, I shall have a read of some of the earlier links provided in these posts.
