Washington — The surface of the sun has been surprisingly calm of late — with fewer sunspots than anytime in in the last century — prompting curious scientists to wonder just what it might mean here on Earth.

The question that exercises my mind now is what this means for the global warming debate. Continue reading

“There is surely a correspondence between an exhausted culture and a populace devolved so far into mental dullness that it can’t recognize its predicament. We don’t seem to get how much the industrial production spree of the past 200 years has just plumb worn us out, not to mention the ecosystem we were designed to dwell in” writes James Howard Kunstler under the title “Modernity Bites” this November 26, 2012.
James’ thesis is that we are at the end of the industrial era and that the economic structures it has spawned are imploding around us.
What if we just accept the reality that the industrial spree was a self-limiting adventure and now we have to move on?

There are conflicting claims about the greenhouse friendly nature of coal seam gas in Australia. In this article, Colin Hunt finds that the differences turn on assumptions about the quantity of gas that escapes to the atmosphere from coal seam gas operations and the gas’ global warming potential. He argues that both better measurement of the fugitive emissions of coal seam gas and an official update of its greenhouse potency are required. These recommendations have important implications not only for meeting Australia’s greenhouse targets but for the tax rates on emissions under the Clean Energy legislation.

Returning to business as usual as soon as possible was the mainstream mantra after September 2008; such was the shock of the collapse. A crash like that is never an easy time for considered reform and few countries had the resources to make any serious attempt in any case, so invested were we all in the good old days of cheap abundant energy and exponential growth. August 2011; here we go again?
The Question: (from Amanda in the USA)
Saving the planet or maximising a growing opportunity? Is low carbon construction a sustainable model?
I’m trying to ascertain whether construction companies are following low carbon strategies to save the planet, to follow the crowd or to benefit from genuine contract opportunities. Will low carbon and sustainable projects offer life support to many recession-challenged SMEs? Is there business for the taking? What do you think?
