New York Sunset August 29 2011

This sunset photo following Hurricane Irene in New York City is beautiful.  Taken by Inga Sarda-Sorensen which I found through my Twitter Feed, it underlines the amazing combination of modern communication technology to embrace some truly incredible natural scenes.

Some Hurricane Irene Links:

  • Hurricane Irene has been tracked by Google Maps here 
  • An interesting comparison of Hurricane Irene and Hurricane Katrina here
  • National Hurricane Centre Irene here

Meeting James Lovelock

Professor James Lovelock and his groupie!

I was fortunate enough to meet and then hear the eminent climatologist Professor James Lovelock speak at the excellent Charles Causley festival in Launceston Town Hall last week.  The 92 year old(!) Professor Lovelock has written numerous books on the concept of the earth organism known as Gaia.  I have long been an admirer and it was great to talk to him so candidly about his rather pessimistic outlook for our planet over the next 20-30 years.  He has been a strong advocate of nuclear power for many years and he made a good analogy of having visited the French Nuclear waste processing plant at Le Hague and then returning to Cornwall where you only have to go to St.Ives to be exposed to three times the radiation!  He was also very dismissive of wind generation and referred me to the excellent Sustainable Energy without the Hot Air by David MacKay, Professor of Physics at the University of Cambridge.  It seems that turning my thermostat down is the easiest contribution I can make to saving the planet as well as buying an electric car if I could afford one!

If you haven’t read any of his books then I strongly recommend the Vanishing Face of Gaia which is very readable but ultimately very depressing.

Google Powered by Solar

I’d love to install Solar Panels on our house but unfortunately we’re not south facing and there isn’t the clear view of the sky we would need to make it economically viable.  I see that Google has decided to generate power in the Mojave desert using solar energy.  Using the concept of the magnifying glass and ant but taken to extreme where temperatures in excess of 1000 degrees can be achieved.  I really like the map above as it gives an indication of the size of the earth that would need to be covered to generate solar power for the entire world.  What a fantastic revenue for sub saharan African countries which could also help them to develop in a sustainable fashion.  More info here

Why Nuclear Power is still the solution

Having read George Monbiot’s excellent article in the Guardian and also been a keen follower of James Lovelock and his Gaia theory, both supporters of nuclear power, I’m keen that the argument for nuclear power should still be balanced and not skewed by the disaster at the Fukushima Nuclear power plant.  The fact that Fukushima was over 30 years old ,remained standing following the largest Japanese earthquake in recorded history, then was inundated by the tsunami which was 14 metres in height and only then had a relatively minimal release of radiation, shows that the fear of nuclear power is greater than the actual effects.

Obviously I wish I could afford  to buy, along with everyone else, solar panels, drive a Nissan Leaf, a ground heat pump and install a wind generator in my garden as a green solution but it’s still not a logical economical choice.  Bring on a regulated, modern nuclear power industry and build it in Cornwall to guarantee jobs for the future and get GAIA back to its human friendly state.

UK Freeze = Global Warming?

OK so my attempts at making snow people aren’t great but my Stasi hat bought at Checkpoint Charlie gives it a certain authoritative look.  Didn’t stop the local hoodlums from tormenting him and his carrot nose was last found in an inappropriate place.

So how can this cold weather be linked with the theory of global warming.  The problem with many of us is we tend tyo be very Eurocentric and our thinking doesn’t extend beyond our local area.  Fortunately we now have satellites that can provide a far more detailed view of our global temperatures.  By using the brilliant NASA temperature anomaly tool here we can examine temperatue differences across the globe.  A simple data input can give us the following summary map for the World.

Global Temperature Anomalies - November 2010

Global Temperature Anomalies - November 2010

As you can see the cooler blue sections over Scandinavia and the UK are dwarfed in size by the deep red over the remaining continental landmasses in the northern hemisphere, especially over northern Russia and North America.   The temperatures in western Greenland, northern Canada and Siberia were between two and ten degrees higher than usual. A graph by latitude shows the significant anomaly in the northern hemisphere.

Graph of temperature anomalies nov 2010

Graph of temperature anomalies nov 2010

According to NASA’s datasets, the world has just experienced the warmest January-November since the global record began, 131 years ago. 2010 looks likely to be either the hottest or the equal hottest year. This November was the warmest on record.

Thank you the the excellent George Monbiot article here for making this all very clear and pointing out to the naysayers and bumpkin climate ‘experts’ that our climate is far greater than the picture of snowmen outside our windows!

Google Earth Climate Change Met Office Layer

Met Office Climate Change

The UK Met Office Hadley Centre with a variety of other agencies has produced a fantastic Climate Change layer for Google Earth.  It looks at a change of 4 degrees on climate change and their associated possible impacts.  Like all climate change mapos there is a degree of uncertainty but if I was to trust any scientific body to produce an accurate forecast then the Met Office would be top of my list.  You can download the KML file here but you will need to have Google Earth installed first.  Good video on Channel 4 news about the layer here.

Earth 2100 – A Grim Future?

Earth in the Year 2100
Could you make a video to explain what life will be like in 2100?  It
looks like a pretty depressing future according to the briefing which
talks about the Arctic having melted, rising sea levels, coastal cities
abandoned, disease widespread and conflict. 

I sometimes find teaching modern geography a little depressing and this game seems to highlight it.  Hoefully as Boserup said
‘necessity is the mother of invention’ and the doom mongers will be
proved wrong.  Thank you to Abi H in my year 13 Geography for finding
this link.

Beautiful Sea Creatures

We know more about the surface of the earth than we do of our own ocean.  What other astonishing animals are there lying undiscovered? 

These beautiful animals are called Nudibranchs which are soft bodied, shell-less molluscs or their scientifc term of sea slugs.  When you see how beautiful some of them are you’ll realise how I find it amazing that they belong to the same group of animals that eat all the plants in my garden.

The International Space Station View!

Here‘s a ‘view’ of earth from the International Space Station.  How cool is that!  Thank you Mr.Caine

The virtual tour is fun too!

Fusion and lasers creating energy

1


The BBC has an article about future the future of energy production could be in the use of lasers squeezing together atoms of hydrogen.  But I thought lots of energy was needed to create a laser in the first place?  Who knows?  Well I guess the scientists at the Iter Fusion venture do.
