More sea ice has melted in the Arctic this summer than at any time since satellite records began more than 30 years ago, scientists say.

It is thought a natural warming and cooling cycle could be responsible for up to 30% of the melting - but the rest is the result of human activity releasing greenhouse gases.
Roger Harrabin reports.

And deniers say , there has not been any increase in warming or Arctic ice for a few years .

This is just natural for the Earth to do.. right.. right!?

I kid but it's a sad state of affairs..

The problem is is that there's no proof to show whether greenhouse gases are causing the arctic to melt.
My thoughts are that it's much more probable that the sun's cycle and nature has more to do with it.
Regardless, we just don't have enough data to show any sort of reliable trend.

I believe that its Co2 but your right nobody really knows , but we should stop going business as usual just in case its Co2

I think the proof is all around us an a majority of scientists certainly agree to the idea of climate change. We've seen an increasing number of droughts, forest fires and freaky weather including soaring temperatures.

There's also a large agreement in most of the worlds scientific bodies that global warming is happening and by and large man-made.

Of all the greenhouse gasses being put into the Ozone, Mankinds contribution makes up a tiny percentage. We get hugely outclassed by Bovine Methane Emissions (Methane is 100x better at being a greenhouse gas than CO2) and Volcanos. Most of what decides the planets temperate depends on the output of the Sun anyway, and that fluctuates wildly.

The factual origin on this are probably the same as :http://www.neowin.ne...t/page__hl__ice

It suggests that it is a natural but uncommon phenomena.

That's not really true though when Methane is said to be around 20 times more powerful than CO2 and cows amount to around 3% of Britain's overall greenhouse gas emissions...

I agree that the weather has been interesting over the past 10-20 years or so. I remember as a kid having crazy winters with multiple feet of snow at a time, and now in recent years, we have been lucky to not have a green Christmas. Through 2 years ago we had an absolutely terrible winter, so it was a bit of a combo-breaker.

But overall, who's to say that it's not just the tip of a 100 year cycle or something? Maybe we'll start to have less natural disasters and more regular-defined seasons as the cycle recedes or starts over. Once and a while you'll hear about some temperature record from 1893 or whatever that was broken, but then you have to consider that those temperatures occurred back then as well, so it really isn't so out-of-the-ordinary. All it will take is a 5-10 year stretch of more "normal" or "better than normal" weather and the whole "global warming" theory will be brought to it's knees.

The increased road tax on high emissions vehicles has worked then. Putting people out of pocket for a good cause and all that.

Given that cows are bred for human consumption are you claiming that their emissions shouldn't be counted as man-made? If their emissions are such a concern then we should switch to more environmentally friendly food sources. As for whether the majority of CO2 is man-made or not, that can be determined by examining the balance between carbon-13 and carbon-14 isotopes. As you will see here, CO2 production from human activities (30 billion tons) is 130 times greater than that from volcanoes (145-255 million tons). As always, before you repeat an opinion you heard elsewhere it is always worthwhile to verify it.

The idea that anthropogenic climate change is disputed in the scientific community is simply wrong.

I don't think that global warming is really a theory anymore considering the science has shown that temperature has increased from around the 1850's. I wouldn't consider you having a terrible winter proves that the temperature is dropping globally though...

Also read that's thought that a volcanic eruption only effects the atmosphere surrounding it for around 2 years.

If you have a glass full of water a simple water drop will make the glass of water overflow.

it was perfect balance of co2 released and consumed by plants , we came around produced more co2 and chopped down the plants.

That is true , Joe public believes if there is a bit of snow on the ground global warming and climate change is not happening.

They don't seam to realise that there is a world outside there house.

Who says it was a perfect balance? The levels of CO2 aren't what drives plant growth.
