These posts are intended to share information and ideas about climate change and hence act as a roundtable for readers to contribute items of interest. Again, I do not want to spend time in comments rehashing whether human activity causes climate change.
This edition is a mixture of science and implementation issues that found me rather than I found them. A couple came from Mark’s Facebook. The last item was drawn to my attention by John D.
1. Electric tents
If you want a tent for the holiday period that stands out from the pack and generates enough electricity to power computers, phones, cameras and loud speakers then
Bang Bang Tents is for you.
2. To frack or not to frack
Britain has announced plans to dramatically cut taxes on fracking profits, from 62 per cent to 30 per cent.
Friends of the Earth say the shale gas tax breaks
could potentially breach EU law because they may represent “unlawful state aid” – putting shale gas operators in a “more favourable tax position” than the traditional North Sea producers.
The Treasury thinks not as it is a new industry.
The cross-party Environmental Audit Committee thinks otherwise and points out that Britain has promised at the Rio+20 summit and the G20 to phase out fossil fuel subsidies.
3. Harvesting subway heat
London plans to warm homes by harvesting subway heat.
4. Global Warming Since 1997 Underestimated by Half
A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated. The reason is the data gaps in the weather station network, especially in the Arctic. If you fill these data gaps using satellite measurements, the warming trend is more than doubled in the widely used HadCRUT4 data, and the much-discussed “warming pause” has virtually disappeared.
The full story is at RealClimate.
NASA GISS fills the data gaps by interpolation from the edges of the “Arctic hole” where there are no weather stations whereas HadCRUT and NOAA leave the gap unfilled.
Now Kevin Cowtan (University of York) and Robert Way (University of Ottawa) have developed a new method to fill the data gaps using satellite data.
This is the result:
The heavier lines represent the corrected values.
5. Typhoon Haiyan
Dr. Jeff Masters’ WunderBlog takes a look at the conditions leading to the intensification of Typhoon Haiyan.
A remarkable warming of the sub-surface Pacific waters east of the Philippines in recent decades, due to a shift in atmospheric circulation patterns and ocean currents that began in the early 1990s, could be responsible for the rapid intensification of Super Typhoon Haiyan.
The ocean 100 meters below the surface under Haiyan was about 3°C above average.
Also the trade winds have strengthened and pushed a large amount of water up against the east coast of the Philippines in the past twenty years, resulting in a rate of sea level rise of 10 mm per year – more than triple the global average of 3.1 mm/yr. The sea there has risen about 305mm (one foot) since 1949.
6. Sea levels no longer included in State Government planning
The Qld State Government has removed sea level rises from planning policy “so as not to inhibit development and to allow councils greater independence in deciding development issues.”
According to a leaked Property and Infrastructure Cabinet Committee paper:
“Any local government that elects to include some allowance for sea level rise in their planning schemes will need to justify that the state interests relating to economic development are not materially affected by this.”
Mr Seeney said the SPP was landmark reform that would revolutionise the way councils, the development and construction industry and the State worked together.
The climate deniers in government seem very pleased with their handiwork and point out NSW went down this track a year ago.
