So, "greenhouse" gases are not new...
They've been around for millions of years?
nobody's bothered to suggest this yet but................. maybe the sun's just got a bit hotter!
Rogue - I'm with you on that
I started my contributions by stating that I was a bit of an old hippy, I think it's great that we try to minimise all pollutants we manage spew out (personally I drive as little as possible - anywhere up to a mile. I'll happily walk, or up to 10 miles, I'll cycle - my cars run on LPG - my "green credentials" are probably amongst the best you can have - ok, so I do have a big motorbike too - but I'd run that on LPG if it was possible, but they don't do a conversion for it yet). I also believe we should get off fossil fuel completely, what a waste of a fantastic chemical resource, to just burn it. Then there's the politics - we wouldn't have to have anything to do with a bunch of tribal war lords, if we didn't need their oil to burn, they wouldn't have the money to fund international terrorism etc
But what we have here is the biggest scientific fraud that has ever been perpetrated
If we do not burn fossil fuels for energy then that leaves us nuclear power, is the waist left behind by this proses possibly far worse for future generations than fossil fuels?
Agree with you there easy, geothermal is the major player for energy. Take Iceland for example. All power is created by geothermal methods. All hot water systems for CH etc is geothermal.
All we need is a big drill...right I'm off to B & Q for a 1 metre diamond drill bit and 7 miles of extension bar...tally-ho!
True north is always to the poles. Magnetic north moves slowly due to the rotation of the inner-core of molten iron....eventually the field will "flip" (change polarity). The "flip" will take a few thousand years. In the time in between the fields not existing and then changing....most life will suffer quite drastic changes.
Nice pun GnV!
The molten rock beneath our feet is caused mainly by the radioactive decay of uranium, potassium and thorium, so the entire earth behaves like a nuclear fission power station.
This source of energy is practically un-exhaustible so it would make sense to have electric vehicles that are powered by the electricity generated by such measures. Cut emissions to zero. and if we go back to planes having propellers and those propellers driven by electricity then we have zero air emissions similarly with ships.
The technology is there, its just the will that is required.
I was looking into the changeover from horses to cars on the net. There isn't a great amount of detail. But the change was very rapid, within a few decades. I don't know if there was another idea that encouraged people to change. But it seems it did not take much persuading.
So I think the main outcome of climate awareness will be the replacement technologies, which manufacturers are already gearing up for profitability.
Whilst on form in the pun department, there is great store being placed on the development of new technologies for electric cars.
Do I understand this correctly? these cars require some of the worst type of material available for their batteries making their "carbon footprint" many times worse than their carbon (petrol or diesel) equivalent.
And will GB save the world again by going to Copenhagen 2 days earlier than originally planned? Milliband must be spitting feathers as it is clear GB can't trust him with anything other than making the tea.
All the 'lecky cars will use Lithium-ion batteries.
The worlds supply of Lithium comes from Bolivia.
They have already stated they will not continue selling the raw material.
The reserves of Lithium are calculated to last ten years at current usage.
Not only that, but with usage of other rare metals such as Indium, Tantalum, Gallium and also Platinum increasing to fuel demand for consumer electronics (flat-screen television, mobile phones and photovoltaic cells) we may soon reach a point where the supply cannot meet demand. (Platinum is also used in catalytic converters) (the price may soon reach a level where thefts of catalytic converters may increase)
Maybe some are already seeing the reason for the clamour for reduction of production ?
jeezzzzz they have arnie on the stand now.
wish he would terminate and bloody lot of them overpayed/pocket lining tossers.
It scares me that so many people don't believe in anthropogenic global warming despite all the evidence.
The rate of warming cannot be explained without taking the massive amounts of human sourced CO2 into account. The effects of this warming is not certain, but I say we have to err on the side of caution and act as fast as possible.
What if..whilst sitting round waiting for more research we miss the boat and find our paddles floating downstream(sorry about the mixed metaphor)
As for the limits of climate records....Archaeologists have been plotting and following climate change going back for thousands of years for quite a while now using core samples and dendrochronology etc.
With most things in life I can be convinced one way or the other with a reasoned argument but years down the road in this debate and I have yet to see anything other than polarised positions and expansive sound-bytes about the climate situation (drought) in north east africa, the floods in Bangladesh and the receding Arctic. It is as if these emotive situations demand an acceptance that global warming is man made but the pure logical arguments have NEVER been presented to the general public.
These are my points which I have never seen answered:
1) Why can't we, the world population, be trusted to see the raw temeprature data and if necessary and explanation as to why corrections are added and what is the result when the corrections are added - ie before and after.
2) When I was at school I was told the Carbon Dioxide is an important part of the atmospheric cocktail because it provides nourishment for all plant life. Also I was told that carbon dioxide is a heavier than air gas meaning that it sinks to the surface. Why then are aircraft singled out as "super polluters" giving inference that carbon dioxide is a pollutant and that it is not a heavier than air gas. Also how is carbon dioxide measured against altitude when it is very much heavier than air and if this is the case, would low lying land not be subject to more global warming than higher land?
3) How exactly is carbon dioxide heating the atmosphere? If it retains heat more than nitrogen and oxygen how come we still get bitter frosts on cloudless nights and how come it is always colder on a cloudless night than on a cloudy night.
4) On a cloudy day, even in the middle of summer we don't feel the heat like we do on a cloudless day when the sun is beating down. Taking into account the points made in (3) about clouds and the point made here about clouds surely the biggest effect on temperature is water vapour? Bright sunshine on solid ground makes the ground hot and the adjoining air is hot too, this does not happen on a cloudy day. Bright sunshine on the sea does not make the adjoining air hot - in fact we know all about on shore and off shore breezes.
5) Volcanoes chuck out a gazillion times more carbon monoxide, sulphur dioxide, methane and carbon dioxide than we humans can produce and they are accepted by the pro lobby as serious greenhouse gasses but we have no control over them whatsoever and yet one of the busiest times for volcanoes was in the last ice age.
6) When I was growing up in the time of coal fires, you could hardly walk the streets at night in Winter because of smog and pollution. Did that not have an effect on the climate?
These points are in the forefront of mind because they are basic facts that were taught at school and I just want to see a non polarised debate where these issues can be reasonably discussed and I would be willing to be swayed, one way or the other. I am just somewhat sceptical that after a billion years of earth's existence, we now claim that in the last few years that we humans are affecting the earths climate - I think that is a touch arrogant.
Nobody has yet managed to explain why the 5% (4% production, 1% land-change) of the CO2 in the atmosphere that WE put there has such a dramatic effect on climate that the other 95% of CO2 in the atmosphere (that is not the result of human activities) does not.
In THEIR world (climate-change-scientists) they can only explain the effect by hypothesising an "unknown forcing mechanism" to cause the "warming".
In a world of sense, scientists would not just say "the warming must be due to mankind but since we don't know why we'll have to invent a reason that is not known to explain it"
The REAL reason why scientists and politicians will NEVER let-go of AGW is because of the money involved.
The amount of money is staggering: Some tens of trillions of dollars. Everyone wants a slice of THAT cake.
And that does not even take account of the political control of the population that is involved.
Have a read of to get an idea of exactly WHY polos are really keen on "climate change"
Or maybe a read of for a thoughful look at the warmist world.
Or maybe even approach to global "warming"
But let's consider what would happen if the opposite was occurring, that is global cooling?
What could man do to stop cooling? The ice would creep over the top and bottom of the earth. Could all that carbon then stop the ice? Probably not.
Global cooling suits as well as global warming: They're both climate change.
Maybe you don't remember the mid 1970's with its "we've got to change or we'll cause another ice age".
The REAL reason for the "climate-change-wars" has just been published in all its inglorious inanity.
Rea and digest just WHY everyone has to change.
And never forget, in the green mind this country is grossly overpopulated; by at least 40 million.
And also consider that control of population, by control of the birth rate, will never produce a viable society.
Soon the clamour that "the old have had their lives so they should let us have ours" will start..................................................................................
Somehow I think that scientists and politicians will be exempt from the "save the world by euthanasia" movement.
And now there's a !
Clear skies for a week and nightime temperatures down to minus 10 - is anyone surprised? No, of course not, clear skies in Winter have always been associated with ice and frost. Question is - in all seriousness - where is the global warming effect (blanket effect) of the the CO2 in the air? Perhaps we should just wait for the clouds to come back for a real blanket effect? I always understood that water vapour was more of a "warmer" than CO2 which is actually an invisible and vital atmospheric gas.
Happy New Year all - Global Warming my Arse.
