Gulf stream pause.

About 8200 years ago the Gulf stream was stopped by the flood of fresh water coming from the melting of the ice sheets on Greenland and North America/Canada at the end of the ice age. This caused a  disastrous temperature drop in Europe of about 5C which lasted for 100 to 150 years.

Picture
Lets hope that this cold patch of cold water in the North Atlantic is not caused by the melting ice sheet on Greenland although there has been a slowing of the Gulf Stream reported in the last few years.

Today's news from the University of California, Irvine and The University of Kansas on accelerating melt from the vast Greenland Zachariæ Isstrøm ice sheet is likely to make the thermohaline circulation increasingly sluggish. Let's hope for rational and urgent action from Paris next month.

I had just finished my post when I saw the news. The ice is melting really fast and it was not included in the IPCC 5th report because not enough was known to give a provable forecast. By the time they work out what is happening we will be up to our necks in water.

An interesting study from Plymouth University out recently on the events after the end of the last ice age . . seems that Scandinavian Ice figured in the temperature drop.

Pleased to see that a 93 page report (Prepare for rising seas - certainty and uncertainty), by Dr Jan Wright, the Parliamentary Commissioner for the Environment was issued yesterday.

Good to see the N.Z Government recognizing the impacts ahead of us, and that our country will not be totally unprepared for what is to come.

In the words of Joe Romm .

"Climate change will have a bigger impact on your family than the internet has had. Imagine if you knew a quarter-century ago how information technology and the internet were going to revolutionize so many aspects of life. Imagine how valuable that knowledge would have been to you and your family.

We have such advanced knowledge of how climate change will play out over the next quarter-century and beyond. Those who have that knowledge will do vastly better in the world that humanity is remaking than those who do not."

Unfortunately our government appears not to accept the excellent work of Dr Jan Wright. Downright disappointing news in the N.Z Herald . .

Excellent and timely program on the Antarctic and climate change from T.V 3 - applause from me for today's 3D program - the best short climate change bite I've seen on N.Z Tele . . by far

I missed that when it as aire here but it is very good. I met Tim Naith, the leader of the NZ team, when I was in Wellington and a lot of the information about the dry valleys was in a course on Antarctica I did on the internet with the Univercity. You can tell from his voice that he is very concerned for the future.
