Geoengineering : Seven extreme climate fixes

Given how the United States are burning, it is not extraordinary that National Geographic published in mid July on geoengineering, or if you prefer, solutions to alter directly our warming climate.

Among those solutions are pumping up plankton, artificial volcanoes, seaweed farms (something new), biochar, greening the desert (see this post), cloud making ships and white roofs.

As you can see, I already had covered most of these solutions except seaweed farms. I think this pretty covers everything, except that we need to cool back the poles…

Worth an article – my September 2011 tweets

I have been committed since January 2007 to bring you each month a selection of the latest headlines and best researches on sustainable development, climate change and the world energy sector.

However, I don’t blog as much as I would like to and generally write around 25 posts per month. But many more news are worth reading. This is why I use Twitter to share more news that are worth your time.

I believe it offers a good complement to this website. So if you are on Twitter and like this selection, don’t hesitate to start following me.

An interesting geoengineering idea

eucalyptus-forestI was previously noting that  the Sahara desert is slowly turning green. To a new study hurrying the process and extending it to the Australian outback by planting eucalyptus trees (left) could absorb our global CO2 emissions.

Indeed this geoengineering idea would absorb eight billion tons of carbon a year. But we shouldn’t forget that like with any geoengineering project this would need huge funds and many technical difficulties would arise.

All this is pretty interesting but for two trillion dollars per year, I believe that  investing in the protection of existing forests would prove as profitable.
