http://thinkprogress.org/climate/2013/0 ... ?mobile=ncThe Jet Stream: How Its Response To Enhanced Arctic Warming Is Driving More Extreme Weather
We’ve written extensively about how how arctic ice loss is driving extreme weather. We’ve known for a long time that global warming melts highly reflective white ice and snow, which is replaced by the dark blue sea or dark land, both of which absorb far more sunlight and hence far more solar energy.
That is one of the many sources of “polar amplification,” whereby the Arctic warms much faster than other parts of the globe. Now it seems increasingly clear that the amplified Arctic warming in turn amplifies extreme weather by weakening the jetstream (see video here).
The National Oceanic and Atmospheric Administration (NOAA) explained in an October 2012 news release:
The effects of Arctic amplification will increase as more summer ice retreats over coming decades. Enhanced warming of the Arctic affects the jet stream by slowing its west-to-east winds and by promoting larger north-south meanders in the flow. Predicting those meanders and where the weather associated with them will be located in any given year, however, remains a challenge.
The researchers say that with more solar energy going into the Arctic Ocean because of lost ice, there is reason to expect more extreme weather events, such as heavy snowfall, heat waves, and flooding in North America and Europe but these will vary in location, intensity, and timescales.

And morons think there is no climate change!
Food and access to resources will be one of the biggest drivers for political instability in the world.Climate change: how a warming world is a threat to our food supplies
Global warming is exacerbating political instability as tensions brought on by food insecurity rise. With research suggesting the issue can only get worse we examine the risks around the world
http://www.guardian.co.uk/environment/2 ... d-supplies
We in the west will also be impacted. Considering food supply is now an internationalised supply chain..... the food belts of the world will effect us all.All of the studies suggest the worst impacts will be felt by the poorest people. Robinson, the former Irish president, said: "Climate change is already having a domino effect on food and nutritional security for the world's poorest and most vulnerable people. Child malnutrition is predicted to increase by 20% by 2050. Climate change impacts will disproportionately fall on people living in tropical regions, and particularly on the most vulnerable and marginalised population groups. This is the injustice of climate change – the worst of the impacts are felt by those who contributed least to causing the problem."
And the news for home.But from Europe to the US to Asia, no population will remain insulated from the huge changes in food production that the rest of the century will bring.
The number of record-breaking hot days in Australia has doubled since the 1960s, also affecting food output.
