Climate change news

Geothermal Heat

I was having a few dark ales at a beer festival at the weekend when one of my brother in laws said to me, quite randomly, we could have all the energy we wanted just by tapping into the heat in the Earth under our feet. It's true that Iceland exploits geothermal heat but that is a volcanic island with hot springs - but is the heat under the ground that close to the surface? Mines and caves would be a good place to locate a bit of heat - but these places can actually be a bit chilly (especially a limestone cave with dripping water).

Typhoons and Hurricanes

The media have been feasting on supertyphoon Haiyan but the Bishop is a little sceptical of a link with CAGW - go to www.bishop-hill.net/blog/2013/11/9/storms-and-global-warming.html ... just as the BBC hyped the storm that knocked down a few trees, and the odd branch or two, a week or so ago, they have really gone to town on the typhoon that struck the Philippines. No information about fatalities is currently available and yet they are talking about a tragedy on a par with the Boxing Day tsunami. It's a wonder that wasn't caused by CAGW - but perhaps it was in some quarters.

The historical climate debate

A paper by Fabien Locher and Jean-Baptiste Fressoz, 'Modernity's Frail Climate: A Climate History of Environmental Reflexivity' published in Critical Inquiry (2012) is discussed at http://mygardenpond.wordpress.com/2013/04/24/we-are-plagued-by-drought-a... ... in which the French authors have a French view on things, but suffice to say they have a jaundiced view in that they think the current climate debate is far too simplistic. What we need is more of the oomph. Far too much phlegm around.

solar activity and global warming

At http://phys.org/print303060859.html ... we have a paper published in Environmental Research Letters by two British professors that profess in all sincerity that neither changes in the activity of the Sun nor its impact in blocking cosmic rays (the production of clouds) 'can be' 'significant' contributors to global warming. In fact, their research claims solar activity has caused no more that 10 per cent of the global warming that occurred in the late 20th century.

Sea levels not conforming with the models either

This story is at http://notrickszone.com/2013/11/05/scientists-find-that-sea-level-rise-i... ... and comes from Germany but involves a scientific study a the Hebrew University of Jerusalem. They collated data from measurement stations located mainly on the coasts and found sea level estimation had been exaggerated upwards. Global sea levels, they found, were on average just 1mm a year - and by the year 2100 would amount to just 10cm. Only one third of stations showed a detectable rise.

A Model Crisis in the Off

A crisis in the climate models, the computer generated graphs that extrapolate warmth ever higher even though it only happened over a few short years in the 1990s. Some of the models don't even take into account the smaller and smaller rises in global temperature in the early 2000s and none of them take in the flat lining - and now it is beginning to fall. Oh dear.

The Watery Planet

Yes, we live on a watery planet - but the next full plate to follow CAGW as it continues to crumble and come undone at the seams will be a water shortage. How on earth can we have a shortage of water in a world dominated by water - well, read http://wattsupwiththat.com/2013/11/01/water-is-replacing-climate-as-the-... ... a guest post by Dr Tim Ball, a retired Canadian climate scientist.

Geoffrey Parker, 'Global Crisis: War, climate change and catastrophe in the 17th century'

Geoffrey Parker, 'Global Crisis: War, climate change and catastrophe in the 17th century' (Yale University Press:2013) is by a UK historian that has worked in the US for a long time, at various universities. Therefore, he comes from two angles, with lots of information from both sides of the Atlantic. The 17th century was of course the height of the Little Ice Age, and average temperatures were one degree celsius, on average, lower than those of the 20th century. That doesn't sound a lot but that is because it embraces the fact that it was not universally cold.

Gulf Stream - all you need to know

NASA and the asteroid threat ... and Mankind in Amnesia

Okay, it is likely that most Near Earth Objects are in resonant orbit with the Earth, and have been for untold numbers of years, and are probably no danger to humans. Even the Taurid streams, or what remains of them, have probably long ago established resonance, but while that reduces risk does it eliminate it? The Russian meteor in February indicates that a rogue space rock, even one in a resonant orbit, is always potentially a hazard - and has always presented a hazard, from the year dot. Space rocks are part of Earth history - but have not been given their true due.
