A little rebuff to global warming

[blobrana]

Hum,

Yes and no...


OK, it should be widely accepted that humans have raised the global temperature (0.2 degrees this century), this is  a fact. The ice sheets are melting and the sea levels are rising...

But, it should be noted that there are large scale cyclic patterns that may confuse the outcome..

It's been about 10,000 years since the last iceage, we should be due for the next one at any minute: hum, perhaps in next one hundred years or so...
We should be painfully aware, that if (when) it happens, that upto 99% of all northern living creatures will perish in the frozen wastes, nothing will escape the big freeze that may hit us...Anywhere...
 
This fact taken with the latest satellite observations show that we are living at one of the warmest periods of earths history, and that a runaway greenhouse scenario may raise the temperature even higher. But eventually this will be `buffered` by the planet and that eventually the world will get cooler , a lot cooler, dude...

Hum,
The latest data (from traces of deuterium isotope, preserved in tiny bubbles, in Antarctic ice cores) show that the Earth's current climate may last for at least another 15,000 years...
 Er, barring any effects from human intervention, according to a new study of Antarctic ice published in the latest issue of the journal Nature.

Hum,
1658...Twas the best of times, the worst of times...

It seems as if the 17th century solar dip that is linked to Europe's Little Ice Age and to global climate change, becomes even more of an enigma as a result of new      observations by University of California, Berkeley, astronomers.

From 1645 until 1714, early astronomers reported almost no sunspot activity. The number of sunspots (er, cooler areas on the sun that appear dark against the brighter surroundings ) dropped a thousandfold.
 Though activity on the sun ebbs and flows today in an 11-year cycle, it has not been that quiet since.

"Star surveys typically find that 10 to 15 percent of all sun-like stars are in an inactive state like the Maunder minimum, which would indicate that the sun spends about 10 percent of its time in this state."

I imagine that the  `Golf/gulf stream` was affected by that dip in solar output, but luckily something stopped it cascading into a "full-blown  ice age."

Hum,
Why not see for yourself?
Download and run a  climate model software package  to see what may happen this century...
And test to see how predictions may change if the behaviour of the Gulf Stream.
Anyone wanting to join the experiment can download a secure software package, including a version of the Met Office's state-of-the-art climate model, from the climateprediction.net site.

Hum,
i just came across some figures...
This time last year, the whole of Europe was baking with record-breaking temperatures...
The death toll was estimated to have been 25-30 thousand, the majority of which 14 thousand occurred in France as a  direct result from a two week heatwave...
