Climate Change No Longer Linear

Picture: The Bloom Trigger Project Anna Majavu - Could humans become extinct within 40 years as a result of climate change? A body of evidence to support this theory is gaining ground. American climate scientist and professor emeritus Guy McPherson is one of a few climate scientists who believe that the governments and corporations of the world have no real intention of combating climate change, and that it will be up to communities to radically alter their lifestyles if we want some species, perhaps not including ourselves, to survive past...

World of Clean Energy 'Feasible' by Mid-Century

Picture: Reve Tim Radford - A global low-carbon energy economy is not only feasible, it could double electricity supply by 2050 while actually reducing air and water pollution, according to new research. Even though photovoltaic power requires up to 40 times more copper than conventional power plants, and wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy. These positive findings are published in the Proceedings of the National Academy of Sciences by Edgar Hertwich and Thomas...

Greenwashing Our Troubles Away?

Picture: Triple Pundit Glenn Ashton - We live in a world of mixed messages, nowhere more than around the environmental health of our planet. While humans relentlessly fray the fabric of our planet’s natural systems, business and politicians reassuringly coo about how we have shifted toward a more socially beneficial and environmentally sustainable path. Nothing could be further from the truth. Yet rather than dealing directly with our problems, a malevolent industry has emerged whose intent is to sow confusion about the...

Gerard Boyce - In a story that has dominated headlines worldwide over the past few months, Scots were recently asked to decide whether Scotland should become an independent country or remain part of the United Kingdom. They chose to retain the status quo in what was ultimately a very close poll. Regardless of one’s opinion on the outcome thereof, this referendum exemplifies the type of situations, viz. when leaders seek a mandate to pursue major political changes, which will alter the nation’s...

And while it might not have been that big, it certainly was immense and easily the largest climate action in world history with people attending from across the United States and around the world, with 2,808 other climate rallies held today in more than 150 countries. The New York march was attended by notable figures in politics, entertainment, science and the environmental...

Using New Energy Platforms for Industrial Capability: Where Is South Africa's Industrial Policy Positioned?

Picture: Making It Magazine Saliem Fakir - There are three aspects of energy supply that lend themselves to shifting the diversification of a national economy. The mix of supply should reduce dependence on any source, especially if the source creates a foreign dependence or a systems path-dependence that eventually leads to wider risks for the general economy. In South Africa, coal is becoming too constraining. Our long-term dependence on coal for the majority of our energy, both electricity and liquid fuels, makes it hard to...
