How can we be certian that crabon dioxide is causeing globabl wamring when their are thousands of volcanos under the sea.

21 Jan 08 - A powerful volcano erupted under the West Antarctic ice sheet around 2,000 years ago and might still be active today, say scientists from The British Antarctic Survey (Bas), who reported their finding in the journal Nature Geoscience.

 

The finding raises the question whether this or other sub-glacial volcanoes may have melted so much ice that global sea levels were affected.

 

The explosive event -- rated "severe" to "cataclysmic" on an international scale of volcanic force -- punched a massive breach in the ice sheet and spat out a plume some 12,000 metres (eight miles) into the sky, they calculate.

 

"The ash and the sulphuric acid and so on would have been blasted out mixed up with steam from the melting ice," said David Vaughan of Bas, who worked on the project.

 

But volcanoes which are not conspicuously active at present may also be generating heat under the ice.

 

Most of Antarctica is seismically stable. But its western part lies (the part where the ice is melting today) on a rift in Earth's crust that gives rise to occasional volcanism and geothermal heat, occurring on the Antarctic coastal margins.

 

The Hudson Mountains where the volcano was discovered lie close to Pine Island Glacier, one of the West Antarctic glaciers whose flow has accelerated in recent years. "This one is probably producing heat and melt water," said Professor Vaughan. "That would end up under Pine Island Glacier and could be thinning it."

 

"The flow of this glacier towards the coast has speeded up in recent decades, and it may be possible that heat from the volcano has caused some of that acceleration," Vaughan said.

The missing sunspots: Is this the big chill?

27 Apr 09 – (Excerpts) Scientists are baffled by what they’re seeing on the Sun’s surface – nothing at all. No living scientist has seen it behave this way. There are no sunspots.

 

The disappearance of sunspots happens every few years, but this time it’s gone on far longer than anyone expected – and there is no sign of the Sun waking up. “This is the lowest we’ve ever seen. We thought we’d be out of it by now, but we’re not,” says Marc Hairston of the University of Texas.

 

And it’s not just the sunspots that are causing concern. There is also the so-called solar wind – streams of particles the Sun pours out – that is at its weakest since records began. In addition, the Sun’s magnetic axis is tilted to an unusual degree. “This is the quietest Sun we’ve seen in almost a century,” says NASA solar scientist David Hathaway.

 

Our Sun is the primary force of the Earth’s climate system, driving atmospheric and oceanic circulation patterns. When the Sun has gone quiet like this before, it coincided with the earth cooling slightly and there is speculation that a similar thing could happen now

 

Sunspots are dark, cooler patches on the Sun’s surface that come and go in a roughly 11-year cycle, first noticed in 1843. They have gone away before. They were absent in the 17th century – a period called the “Maunder Minimum” after the scientist who spotted it. Crucially, it has been observed that the periods when the Sun’s activity is high and low are related to warm and cool climatic periods. The weak Sun in the 17th century coincided with the so-called Little Ice Age. The Sun took a dip between 1790 and 1830 and the earth also cooled a little. It was weak during the cold Iron Age, and active during the warm Bronze Age. Recent research suggests that in the past 12,000 years there have been 27 grand minima and 19 grand maxima.

 

Throughout the 20th century the Sun was unusually active, peaking in the 1950s and the late 1980s. Dean Pensell of NASA, says that, “since the Space Age began in the 1950s, solar activity has been generally high. Five of the ten most intense solar cycles on record have occurred in the last 50 years.” The Sun became increasingly active at the same time that the Earth warmed. But according to the scientific consensus, the Sun has had only a minor recent effect on climate change.

 

I think the Sun has almost everything to do with climate change.

 

Overall, during an 11-year solar cycle the Sun’s output changes by only 0.1 per cent, an amount considered by many to be too small a variation to change much on earth. But … While this 0.1 per cent variation is small as a percentage, in terms of absolute energy levels it is enormous, amounting to a highly significant 1.3 Watts of energy per square metre at the Earth. There is recent research suggesting that solar variability can have a very strong regional climatic influence on Earth – in fact stronger than any man-made greenhouse effect across vast swathes of the Earth.
