You may have heard talk of the UK possibly seeing some colder weather next week and that ‘things going on’ in the upper atmosphere may be playing a part.
The ‘thing’ happening in the atmosphere is known as Sudden Stratospheric Warming (SSW). When it does happen, it attracts a lot of interest in the UK because it is sometimes linked to the onset of cold weather in winter.
Here we shed a little bit more light on the phenomenon.
What is an SSW?
The term SSW refers to what we observe – rapid warming (up to about 50 °C in just a couple of days) in the stratosphere, between 10 km and 50 km up.
You may have heard of the jet stream which helps to steer Atlantic weather systems towards the UK. Well there are other jet streams high up in our atmosphere in both the northern and southern hemisphere which circumnavigate the Earth from west to east. One of these, the Polar Night Jet, circles the Arctic.
Friday Evening Political Forum: Beyond the Carbon Price
Part 7 of 8: Christine Milne, leader of the Australian Greens, delivers an inspiring call to action as the consequences of climate change are clearly upon us while economically we are continuing a business as usual policy.
The action required is urgent and we need to drive an increase in action through increasing the RET (Renewable Energy Target) in 2012, ensuring Climate Change is a major topic of the 2013 election and immediately stop the expansionist policy of developing coal, gas and coal seam gas mining.

by Jonathan Amos, Science correspondent, BBC News
See below link to the TV Documentary "The Great Global Warming Swindle" and listen to what is said about CO2 "following" the Earth warming.
We have been here before and no doubt be here again........over the long term, an active Sun warms the Earth and equally over a long term an inactive Sun cools the Earth. When the Earth cools, the co2 returns back to the oceans and ice, and when the Earth warms the co2 returns back to the atmosphere from the Oceans and ice. It's a cycle that has been repeated many times before and will be repeated over and over again, long after the BBC and Nature have been removed from repeating the "effect" being the "cause" again!
What is being said in the latest report is that co2 somehow makes the Sun active!!!.......GR
A study by the Scripps Institution of Oceanography in San Diego traced ocean warming to the late 19th century, which implies, say researchers, that the Earth’s climate as a whole has been heating up since then.
The report is the first global comparison of temperature between the historic voyage of HMS Challenger between 1872 and 1876 and modern data obtained by ocean-probing robots now continuously reporting temperatures via the global Argo program....
