The last Open Thread has just slipped off the BNC front page, so time to launch a new one. The Open Thread is a general discussion forum, where you can talk about whatever you like — there is nothing ‘off topic’ here — within reason. So up on your soap box!
The standard commenting rules of courtesy apply, and at the very least your chat should relate to the broad theme of the blog (climate change, sustainability, energy, etc.). You can also find this thread by clicking on the Open Thread category on the left sidebar.
Although I don’t want to direct commentary along any particular pathway, here are a few items I’ve read recently that you might find worth discussing:
1. The Bureau of Meteorology has released a Special Climate Statement on the recent exceptional rain and flooding events in central Australia and Queensland. 28 February was the wettest day on record for the Northern Territory while 2 March set a new record for Queensland. Over the 10-day period ending 3 March 2010 an estimated 403 cubic kilometres (403,000 gigalitres) of rainfall fell across the NT and QLD!
2. A really excellent and easy-to-read paper has been published in the latest issue of Sustainability. It’s called “Is Humanity Doomed? Insights from Astrobiology” by Seth Baum of Penn State Uni. It’s open source (free to download, here). The author is not focused on whether humanity will go under anytime soon, but rather he is interested in a long-term view — especially, what astrobiology has to say about the Fermi Paradox (which I discussed here, way back in the early days of BNC). Fascinating paper.
3. Joe Shuster, in cooperation with the Science Council for Global Initiatives, has published an energy planning primer called “Want to see the future? Look at energy.” (download the 21-page PDF here). It’s a sharp review of fossil fuel limits, smart grids, wind, solar, hydro, biomass and natural gas, and the future role of plasma remediation and nuclear energy in the US energy economy.
His 2040 plan ends up with 42% nuclear, 12% natural gas, 5% plasma arc syngas, 6% bio/geo/tides/waves, 5% hydro and 30% wind/solar. For the latter, he says 30% is really the upper limit he can conceive, with any probable shortfall being met by more nuclear. Cost? About $6 trillion in direct investment over 30 years, but which results in an economy-wide cost saving equivalent of $8.5 trillion (mostly from no longer needing to purchase foreign oil, plus efficiencies etc.). All in all, it’s a plan well worth looking at, and fits nicely with the ‘real-world applicability’ criteria I described here.
