The rise of digital currency like Bitcoin, and carbon footprints

Here i take a look at the rapidly growing Bitcoin currency and technological developments in light of emissions targets. Above video shows a Bitcoin rig June 2011, many computer’s with GPU’s (high power graphic cards), hence high energy consumption. Recent developments David Gilson from Coin Desk writes on June 6th, 2013: We have just observed…

Big Oil’s Big Lies About Alternative Energy

As President Obama calls for greater investments in alternatives, the biggest energy companies are doubling down on riskier, more destructive oil sources By Antonia Juhasz June 25, 2013: Since the Gulf oil disaster in 2010, BP has spent hundreds of millions of ad dollars to cleanse its image as a dirty-energy giant. In the company’s…

Estimating the permafrost-carbon feedback on global warming

A key uncertainty is the fraction of carbon that might be decomposed under anaerobic conditions – resulting potentially in methane emissions to the atmosphere. Given the high warming potential of methane, the overall magnitude of the permafrost-carbon feedback will depend strongly on this fraction. Thawing of permafrost and the associated release of carbon constitutes a…

Weird weather might just wake feeble politicians up to climate change

The Guardian: Meteorologists are debating our role in bizarre weather events. We have the technology for change, but not the political will On Monday, Amory Lovins, physicist, environmentalist, and unassuming colossus of the green movement, appeared in London to talk about energy use. I mention this in the context of the Guardian’s story that meteorologists…

The state of the climate and national security

The release of huge quantities of previously stored “multiyear/deep layer” carbon deposite and equivalent greenhouse gases (CO2/CH4/N2O, from soil and water) can act like a trigger to boot the earth systems. This boot begins initially with a transition phase depending on the rate of emissions and in further development creates several large scale carbon excursions…
