Vidal’s voyage to Durban

How better to journey to the climate conference at Durban than through the African countries along the way which are already grappling with climate change? That’s the route John Vidal, the Guardian’s environment editor, has been following over the past ten days and reporting on in a series of articles.

He started in Egypt. The impacts of climate change are difficult to disentangle from natural coastal processes and the effects of human activities on the flow of the Nile, but an inexorably rising sea level and the increasing intensity of storms threaten increased salination of groundwater and soil as well as inundation. Extreme heat will also take its toll on city life.

The Climate Show #22: Durban doubts & Renwick on extremes

[youtube]HTL6EKXiIvU[/youtube]

A crisp and crunchy show this week, as Gareth and Glenn interview Dr James Renwick about the IPCC’s cautious new report on extreme weather and the riskier future we all face. With added ruminations on the potential slowdown in international action at the Durban conference, record greenhouse gas levels reached in 2010, the prospect of “hyper warming” and the release of some lightly warmed over stolen emails. No debunking a la Cook this week, but he’ll be back soon, and we have news of the world’s first hybrid jet aircraft.

The promise of renewables

No sooner had I finished reviewing Fools Rule, which recounts the determination of many nations to carry on with the further discovery and exploitation of fossil fuels in blunt defiance of the warnings of science, than I read Fred Pearce’s article in Yale Environment 360 detailing how the world is in fact burning more and more coal. He pointed to the irony of the forthcoming UN negotiations in Durban, South Africa, where the talk of how to kick the coal habit will take place in a country with high CO2 emissions and a thriving export industry in power-station coal. Not that he was singling out South Africa – the trend is shared over many countries. As if in confirmation our Prime Minister on the same day, during the leaders’ debate, affirmed yet again his government’s commitment to expand mining and drilling operations – in an environmentally responsible way, of course. He offered Australia as an example of the prosperity to be obtained thereby.

We have the technology, but…

One word sums up the attitude of engineers towards climate change: frustration.” That’s Colin Brown, director of engineering at the UK’s Institution of Mechanical Engineers, writing in the latest New Scientist. Political inertia combines with continuing noise from the vocal minority of sceptics to mean that we are doing woefully little to prevent the worsening of global warming.

It’s not as if we are lacking the technology:

Engineers know there is so much more that we could do. While the world’s politicians have been locked in predominantly fruitless talks, engineers have been developing the technologies we need to bring down emissions and help create a more stable future.

Wind, wave and solar power, zero-emissions transport, low-carbon buildings and energy-efficiency technologies have all been shown feasible. To be rolled out on a global scale, they are just waiting for the political will. Various models, such as the European Climate Foundation’s Roadmap 2050, show that implementing these existing technologies would bring about an 85 per cent drop in carbon emissions by 2050. The idea that we need silver-bullet technologies to be developed before the green technology revolution can happen is a myth. The revolution is waiting to begin.

The barriers to a low-carbon society are not technological but political and financial, he declares. That’s why at a London conference this month 11 national engineering institutions representing 1.2 million engineers from across the globe decided on a joint call for action to be presented at December’s COP17 climate change conference in Durban, South Africa.

The Climate Show #12: twisters, Olaf on ozone, and Google in the sun

[youtube]udadT7eDWYQ[/youtube]

Ozone is the centrepiece of our show this week, with Dr Olaf Morgenstern of NIWA’s Central Otago atmospheric science lab (celebrating its 50th birthday at the moment) explaining the ins and outs of the ozone holes north and south, and their impacts on the climate system. Plus tornadoes, heatwaves, UN negotiations at an impasse, more melting in the Arctic, airships, see-through solar cells and Google’s solar towers. No John Cook this time — he’s been too busy launching his book (good luck with that John!).
