Glacier melted long before climate change

Scientists have argued that the Pine Island Glacier was melting just as quickly over 8,000 years ago.
The glacier has long been considered to be the perfect example of how carbon emissions have been affecting the environment, but now experts at the British Antarctic Survey have revealed that the glacier had been melting at a similar rate several thousand years ago, long before mankind had been capable of having any impact on the world's climate.

The glacier, the melting of which is believed to be contributing to rising sea levels, is thought to have experienced periods of extensive melting at various times throughout history. Rather than being the result of man-made global warming, the melting is simply something that seems to occur from time to time regardless of human activity.

"The results are clear in showing a remarkably abrupt thinning of the glacier 8000 years ago," said Professor Mike Bentley who worked on the research.

What you want to force on people will not work. Why? Because, we either do not have the tech, or it is too expensive. Energy companies are controlled directly or indirectly by state and/or local governments.

That's not entirely true. Citizens United allows companies to use their profits for political campaigns. The result is billions of dollars in "campaign contributions," otherwise known as bribes. The public discourse (and the government) is being bought out by big money. We have the best politicians money can buy. Doug

I've just been struck by a thought...that all these controversial subjects are smoke screens, so what could they be hiding, if anything? What was going on before Global Warming became an issue... What was going on before UFology became mainstream... Is anyone monitoring the 'Random' machine, forgot where it is.... Anyway, apologies for the digression but agree that we should have alternatives to being reliant on 'Corporates' for day to day living, as it was in my childhood, no probs back then... Still, Putin seems set on putting us all back there anyway, what with WW3 loomi... [More]

I am skeptical of the AGW hypothesis for several reasons, but that is immaterial, really. Because even if I were 100% sure it was true, I would oppose any attempt to have Government "fix" it. Governments are good at two things, generally: 1)waging wars, and 2)getting bigger. Climate Change legislation would just turn out to be number two. Who honestly thinks government policy could "save the planet"? It takes only a cursory glance at recent history to see that this is extremely unlikely. Australia tried a Carbon Tax. Big fail. And who is going to make China, Russia, India, ... [More]

At 7 cents per KWH, wind is cheaper than any other form of energy, except natural gas-fired turbines and it is neck-and-neck with that - to the extent that which is cheaper depends on distance to market and whether there are existing pipelines and transmission lines to carry it. Coal plants, even new ones, cost 11 cents per KWH. Solar isn't there yet, but it's coming. So what do you think is "modern"? How about a steam engine? That's what a nuclear plant is: nuclear power generates steam to run a generator. Coal plants are steam and so is natural gas. Some solar... [More]

Your basic premise is entirely flawed, the Government has a proven track record of solving environmental issues. The EPA (the one your slated in another thread) has been responsible for cleaning up the American environment within the last 50 years. Low level smog is a tiny fraction of the problem it was across American cities which has directly saved 100,000's of lives. That was a government initiative. The UN treaty on CFC's has arrested the decline, and put it into reveres, the hole in the ozone layer. Correct government action can solve significant problems if the will is there.... [More]

Back to the subject of the thread: Prior to human intervention in the climate system, there was an ice age about every hundred thousand years. That has been going on for 12 to 15 million years. Between each glacial cycle there is an interglacial during which time the climate warms up, sea levels rise and so on. America owes its large number of southern pine species to the periodic isolation of pine populations caused by rising an falling sea levels. Rising and retreating ice sheets allowed the Niagara River to carve a whole bunch of gorges through the Niagara Escarpment, the St. David'... [More]

And if it is man caused.
