After watching the prog on BBC4 last night, I now tend towards the Global Warming is actually happening and is caused by greenhouse gasses. Anybody else see it?
Global Warming .. yet again

no, but we had an article in a lokal newspaper ( in finnish ) that the Greenland glacier 10 years ago was melting 90 cubickm/ year and now 220 ! When it all has melted the waterlevel i8n oceans increases by 7m. Guess there will be a lot more boating people in the future.

Desperate Global Warming ?
I saw that program. Okay, so they drive around in gigantic cars, but the thrust of the program surely wasn't that global warming is increasing, was it? The more obvious conclusion was that that Desiree felt bad about sleeping with her pharmacologist, and that one of the other housewives seems to be happier at work than at home?

seems that although the glaciers are melting at the fringes, they're getting bigger by more than the peripheral loss because snow's falling on the top (thro' global warming climate wetter and its coming down as snow) so we'll soon have vertical glaciers or skyscrapers ...

actually the volume of the glaciers worldwide is decreasing. /forums/images/graemlins/confused.gif

I fell asleep towards the end, but agree that there is "something" happening. Watch out for the ones who don't get the name though and can't understand that much of the world'll actually get colder- Michael Crichton wrote a godawful book "State of Fear" that aims to nay-say all fears of this and make anyone concerned seem a zealot, using a hugely biased/imbalanced bibliography to make simple folk think it's well researched and "true".
Global temperatures may be cyclical even, but huge great holes in the planets protection ain't.
Anyone want to teach me ice-sailing?

I have kept quiet since having the cheek to suggest global warming is real last year and getting crucified for being a gloom and doom merchant. I am 63 so probably might even see some short term advantages in the weather but am very worried for my grandchildren's sake longer term. Who else is as frustrated as me that everyone has their head stuck firmly up their bumholes on this issue? Until we vote for people who care and actually dare to do something, we will condemn our grandchildren to living with a problem that cannot be reversed......

This is copied from a previous global Warming post well worth a look on the web site it explains a lot that is missed by TV programs.

Our Future Written in Stone
--------------------------------------------------------------------------------
Today the Earth warms up and cools down in 100,000- year cycles. Geologic history reveals similar cycles were operative during the Carboniferous Period. Warming episodes caused by the periodic favorable coincidence of solar maximums and the cyclic variations of Earth's orbit around the sun are responsible for our warm but temporary interglacial vacation from the Pleistocene Ice Age, a cold period in Earth's recent past which began about 2 million years ago and ended (at least temporarily) about 10,000 years ago. And just as our current world has warmed, and our atmosphere has increased in moisture and CO2 since the glaciers began retreating 18,000 years ago, so the Carboniferous Ice Age witnessed brief periods of warming and CO2-enrichment.
Following the Carboniferous Period, the Permian Period and Triassic Period witnessed predominantly desert-like conditions, accompanied by one or more major periods of species extinctions. CO2 levels began to rise during this time because there was less erosion of the land and therefore reduced opportunity for chemical reaction of CO2 with freshly exposed minerals. Also, there was significantly less plant life growing in the proper swamplands to sequester CO2 through photosynthesis and rapid burial.
It wasn't until Pangea began breaking up in the Jurassic Period that climates became moist once again. Carbon dioxide existed then at average concentrations of about 1200 ppm, but have since declined. Today, at 370 ppm our atmosphere is CO2-impoverished, although environmentalists, certain political groups, and the news media would have us believe otherwise.
What will our climate be like in the future? That is the question scientists are asking and seeking answers to right now. The causes of "global warming" and climate change are today being popularly described in terms of human activities. However, climate change is something that happens constantly on it's own.
( If humans are in fact altering Earth's climate with our cars, electrical powerplants, and factories these changes must be larger than the natural climate variability in order to be measurable. So far the signal of a discernible human contribution to global climate change has not emerged from this natural variability or background noise. )
Understanding Earth's geologic and climate past is important for understanding why our present Earth is the way it is, and what Earth may look like in the future. The geologic information locked up in the rocks and coal seams of the Carboniferous Period are like a history book waiting to be opened. What we know so far, is merely an introduction. It falls on the next generation of geologists, climatologists, biologists, and curious others to continue the exploration and discovery of Earth's dynamic history-- a fascinating and surprising tale, written in stone.

As I've said before, the scientific advisory bodies of all G8 nations have warned their governments that global warming is an issue. Never before have scientific advisory bodies gone down such a route. It's without precedent, as scientists usually have difficulty explaining the myriad of layers of science behind such a decision.
The very fact that they all agreed to such a press release tells volumes

That was the very thrust of last night's program. The movement in the last 150 years is not explainable by correlation to solar and volcanic variations (whereas it could for the previous n thousand years) but needs the addition of a SIGNIFICANT factor .. axplainable by changes in greenhouse gas levels..

Reseacrh fusion energy. Build more nuclear stations. Build tidal power stations. Build windfarms. Make protesting against the building of nuclear stations, tidal stations, windfarms etc subject to the Prevention of Terrorism Act. Remember, you saw it here first. Under the current government only the last bit will actually happen...

Nuclear yes, the others are so inefficient we'd have layer upon layer of the things, just supplying local villages.

praps look up info on a place called "tarifa" apparently windiest place in europe, southern spain actually just a bit south of gibraltar. Squillions of wind thingies all whirling around . This isn't a post for or against, tho it was a bit much trying to drive a car along a road nearby...

BrendanS I entirely agree with you the powers that be in the whole world should get their act together and drastically reduce the human output of Global Warming activity. But bar shunting the earth over a bit on it's orbiting path it will none the less do it's own thing. But please don't broad cast my idea of us altering its orbit. The Bl****g scientists interfere with nature far to much as it is.

that one windiest spot will supply a few villages, or a large town. Does nothing for requirements of western world tho.

I suppose you were equally convinced by all the experts on the subjects of the Millenium Bug and Weapons of Mass Destruction. Don't forget that a few years ago these same protagonists of global warming were forecasting the big freeze because of pollution in the atmosphere. When they manage to construct a sentence without using could-might-if it may be time to listen.

Global warming will produce the big freeze- read up on the Labrador Current and ocean conveyor belt. Don't discredit anyone who suggests exercising caution, it can only help, and if we're proved wrong, then there are more resources to play with at a later date.

So called "economic growth" is directly proportional to energy consumption. That's the current paradigm. More energy or change the paradigm its quit simple really.
Climate change is evident to me. I don't remember flooding in the SE UK when I was a child, nor do I remember these 100kt winds that flail the SW UK now. Or maybe I've got no memory - quite possible. Any body else rember these extreme conditions. The Uk has always been a tranquil climate and no earthquakes.
