Real risk of a Maunder minimum 'Little Ice Age' says leading scientist
guest... Thu Oct 31, 2013 11:22 am
It’s known by climatologists as the ‘Little Ice Age’, a period in the 1600s when harsh winters across the UK and Europe were often severe.
The severe cold went hand in hand with an exceptionally inactive sun, and was called the Maunder solar minimum.
Now a leading scientist from Reading University has told me that the current rate of decline in solar activity is such that there’s a real risk of seeing a return of such conditions.
I’ve been to see Professor Mike Lockwood to take a look at the work he has been conducting into the possible link between solar activity and climate patterns.
According to Professor Lockwood the late 20th century was a period when the sun was unusually active and a so called ‘grand maximum’ occurred around 1985.
Since then the sun has been getting quieter.
By looking back at certain isotopes in ice cores, he has been able to determine how active the sun has been over thousands of years.
Following analysis of the data, Professor Lockwood believes solar activity is now falling more rapidly than at any time in the last 10,000 years.
He found 24 different occasions in the last 10,000 years when the sun was in exactly the same state as it is now - and the present decline is faster than any of those 24.

Saw this too. Not looking good.
"There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, they equivalent of almost a million square miles.
In a rebound from 2012's record low an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia's northern shores, days before the annual re-freeze is even set to begin"

lets build more coal fired power stations they will keep us warm and prevent an other ice-age. apparently we have enough coal to last us 300 yrs.Tell the eu to get stuffed and start building them.

the climate alarmist will point out that it is not as thick. the more sensible will realise that it takes time to get thicker.Tess wrote:Saw this too. Not looking good.

the sun is what drives climate change, it is in a cooling phase now so CO2 levels will fall as well. Temperatures rise, CO2 levels follow. Temperatures fall CO2 levels fall, not the other way around.

Actually Dean I am open minded about many things and don't just dismiss things out of hand just because you don't believe them, climate change is very real and you can ignore all the evidence you want, it won't change the fact we have changed the planet!

of course you are. no one denies climate change is real, it has been happening from the first day we had an atmosphere. what is questionable is the man made bit.Didge wrote:Actually Dean I am open minded about many things and don't just dismiss things out of hand just because you don't believe them, climate change is very real and you can ignore all the evidence you want, it won't change the fact we have changed the planet!Flap Gallagher wrote:the climate alarmist will point out that it is not as thick. the more sensible will realise that it takes time to get thicker.

Is it? Seems many people who have studied this strongly disagree with you and rightly so, only scientists with an interest in fossil fuels do not, no suprise there. Even though not one has been able to refute any of their claims in any academic paper, funny thatFlap Gallagher wrote:of course you are. no one denies climate change is real, it has been happening from the first day we had an atmosphere. what is questionable is the man made bit.
