The polar jet stream may be driving a "hemispheric pattern of severe weather."

Scientists are trying to understand if the unusual weather in the Northern Hemisphere this winter — from record heat in Alaska to unprecedented flooding in Britain — is linked to climate change. One thing seems clear: Shifts in the jet stream play a key role and could become even more disruptive as the world warms.

This winter’s weather has been weird across much of the Northern Hemisphere. Record storms in Europe; record drought in California; record heat in parts of the Arctic, including Alaska and parts of Scandinavia; but record freezes too, as polar air blew south over Canada and the U.S., causing near-record ice cover on the Great Lakes, sending the mercury as low as minus 50 degrees Celsius in Minnesota, and bringing sharp chills to Texas.

High methane concentrations have persistently shown up over the Arctic Ocean since October 1, 2013.

The danger is that methane will further warm up the air over the Arctic, causing further weakening of the Jet Stream and further extreme weather events, particularly extreme warming of water all the way along the path of the Gulf Stream from the Atlantic Ocean into the Arctic Ocean, in turn triggering further releases from hydrates at the seafloor of the Arctic Ocean and escalating into runaway global warming.

David Cameron: "Whatever money is needed, we will spend it."

bbc.co.uk - February 11, 2014

The prime minister says money will be no object as flood relief efforts continue across swathes of the UK.

David Cameron warned the severe weather was not over, saying: "Things could get worse before they get better."

Speaking at a Downing Street press conference after returning from the flood-stricken South West, Mr Cameron said: "Money is no object in this relief effort. Whatever money is needed, we will spend it."

He said recovering from the floods could take time, telling reporters: "It will be a long haul and it will require a stepped up national effort, with the whole country pulling together.

He vowed lessons would be learned, adding: "We will deal with the floods and we will build a more resilient country for the future."
