Richard Heinberg on our renewable future

Talk Nation Radio / David Swanson / 25 February 2015

Richard Heinberg discusses our renewable future and how to get there. He is the author of ten books including Snake Oil (2013), The End of Growth (2011), Peak Everything: Waking Up to the Century of Declines (2007), and The Party’s Over: Oil, War & the Fate of Industrial Societies (2003). Heinberg is a Senior Fellow of the Post Carbon Institute. He has appeared in many film and television documentaries, including Leonardo DiCaprio’s 11th Hour, and is a recipient of the M. King Hubbert Award for Excellence in Energy Education.

Survivable IPCC projections depend on geo-engineering

Nick Breeze / 25 February 2015

Currently humanity is on the worst case scenario of RCP 8.5 which takes us to 2°C warming by mid century and 4°C warming by the end of the century. As Professor Schellnhuber, from Potsdam Institute for Climate Research (PIK) said, “the difference between two and four degrees is human civilisation.”

LG Warden Gordon: “There is no global warming”

Brockville This Week / Nick Gardiner / 26 February 2015

WardenGordon1Not only does the Warden question the “settled science” of climate change, he argues carbon taxes have failed badly where they have been attempted in Europe, where some countries are re-thinking policies that have curtailed development and taken money out of the pockets of hard-pressed individuals and corporations.

Such efforts have been “riddled with corruption” and have driven fuel costs up 15 to 20 per cent while doing little to reduce carbon emissions, added Gordon.

Yet, Ontario Minister of Environment and Climate Change Glen Murray is bound to impose the new regulation despite what Gordon maintains is a false argument. “There is no global warming” he said.

The myth about warming up your car on a cold day

Globe and Mail / Peter Cheney / 26 February 2015

car exhaustExtended-idle warm-ups were once encouraged due to lubrication technology. Old-school oils didn’t work well in low temperatures. Modern synthetic oils can flow well at temperatures as low as – 40 C.

Use remote starters wisely. Many drivers start their engines far ahead of time so their car will be toasty warm when they get in. This extended idle has a high cost. According to the Oak Ridge National Laboratory (a division of the U.S. Department of Energy), excessive idling shortens the life of your exhaust system and spark plugs because a cold engine creates more damaging combustion byproducts than a warm engine. Carbon and soot buildup also reduces the effective lifespan of engine oil.

First direct observation of CO2’s increasing greenhouse effect

Science Daily / Lawrence Berkeley National Laboratory / 25 February 2015

ARM stationThe influence of atmospheric CO2 on the balance between incoming energy from the Sun and outgoing heat from Earth (also called the planet’s energy balance) is well established. But this effect has not been experimentally confirmed outside the laboratory until now. The research is reported Feb. 25 in the advance online publication of the journal Nature.

The results agree with theoretical predictions of the greenhouse effect due to human activity. The research also provides further confirmation that the calculations used in today’s climate models are on track when it comes to representing the impact of CO2.

Biofuels not all they’re cracked up to be, study finds

Common Dreams / Deirdre Fulton / 29 January 2015

ethanol“The quest for bioenergy at a meaningful scale is both unrealistic and unsustainable,” says a new report from the World Resources Institute that calls into question Western governments’ support for energy policies that encourage large-scale conversion of plants into fuel.

The study, “Avoiding Bioenergy Competition for Food Crops and Land” (pdf), published Thursday, is a wide-ranging look at the costs and benefits associated with producing plant-based energy, or biofuels. It finds that dedicating crops, such as corn or sugarcane, or land to generating bioenergy—as the U.S. and some European countries are already doing and aiming to do even more—is an inefficient use of the world’s natural resources.

Further, the report states: “[B]ioenergy that entails the dedicated use of land to grow the energy feedstock will undercut efforts to combat climate change and to achieve a sustainable food future.”

The Transition Framework

Resilience is the ability of a system or community to withstand impacts from outside. An indicator is a good way of measuring that. Conventionally, the principal way of measuring a reducing carbon footprint is CO2 emissions. However, we firmly believe that cutting carbon while failing to build resilience is an insufficient response when you’re trying to address multiple shocks such as peak oil, climate change and the economic crisis together.
