Using Nature to Help Build a Green Economy

In Lewis Carroll’s wonderful book Through the Looking Glass, Tweedledee emphatically declares to Alice: ‘Contrariwise: if it was so, it might be; and if it were so, it would be; but as it isn't, it ain't. That's logic.’ 

It’s always a struggle to move beyond ‘contrariwise’. There’s a remarkable inertia in large institutions and industry to get the order of things right. Even when the need is a pressing one.

Our planet is experiencing a frightening number of environmental crises. Extreme and abrupt climate change, biodiversity loss, soil degradation, ocean acidification and deteriorating water quality are just a few of the many important challenges we face on a worryingly large list.  But all are interconnected. Several years ago the United Nations Environment Program launched an ambitious target: for the world to develop a ‘Green Economy’, one which is low in carbon, efficient with resources and socially inclusive. By making the shift to a green economy and move towards a more sustainably-run planet, the UN argue, we can slow and ultimately reverse the collapse in our planet’s ecosystems. With intense international negotiations now happening behind the scenes in the run up to the Paris climate change summit in December, governments are grappling with how to rapidly decarbonize their industries while growing their economies for all. 

Perhaps surprisingly, the green economy is actually worth a fortune. In Britain alone, business is booming, with an estimated value of more than £120 billion and employing over a million people. For the period we have statistics (2011-2012), the green economy was outpacing global growth. It’s an extraordinary statistic that is mirrored around the world but easily overlooked. The question is how to continue this trajectory.

There’s no doubt technology has a major role to play in greening of the world’s economy. As recently highlighted by Sir David King, the UK’s former head scientist and chief negotiator at the Paris meeting: ‘Technology is moving ahead very rapidly. I think we need to focus not only on the details of the negotiations, but also on what the technological revolution is going to bring to us.’ The good news is we now have an arsenal of green technologies, both old and new, that can be brought to bear on helping the world decarbonise its economy.

My own involvement in supporting this ambition began with the modest potato. At thirteen years old, I was left at home on one of the rare occasions my parents went out and decided to use the recently arrived microwave for dinner. Not understanding the difference with a conventional oven, I set the timer to cook on high power for a shocking 40 minutes. The inevitable result was a house filled with smoke, one dead microwave and a glowing black lump where the potato had once been. It was one of those painful life experiences one tries to forget but it held the nugget of an idea: to use microwave energy to make green products. The resulting New Zealand company is called CarbonScape and flourishing. Moving beyond potatoes, we are designing and building tailor made microwave devices that can turn forestry waste and other biomass into a host of carbon-neutral products, including activated carbon, green coke and other fuels, chemicals, and even biochar for locking carbon out of the atmosphere. Since its formation, the team has gone from strength to strength, becoming the Judges Top Choice in the Financial Times Climate Change Challenge and runner up in the 2012 Postcode Lotter Green Challenge. This year we raised over $860,000 through crowdsourcing, the largest raise to date in New Zealand. 

Like many green tech companies CarbonScape is cost competitive. But replacing old industries is a challenge. This year the International Monetary Fund reported the shockingly high global fossil fuel subsidies that total some £3.4 trillion ($5.3 trillion) a year, equivalent to an eye-catching $600 million an hour. These subsidies artificially keep fossil fuel products relatively cheap, holding back the adoption of green technologies. It’s not a level playing field.


If we really want to get away from being contrariwise and help the green economy take off, we can only hope Paris does away with the fossil fuel subsidies.

500 years of drought and flood: trees and corals reveal Australia’s climate history

500 years of drought and flood: trees and corals reveal Australia's climate history Patrick Baker , University of Melbourne ; Chris Turney , UNSW Australia , and Jonathan Palmer , UNSW Australia Australia is the land of drought and flooding rains, and in a recent paper we’ve shown that’s been the case for more than 500 years. As part of our Australia and New Zealand Drought Atlas we’ve published the most detailed record of drought and wet periods (or “pluvials”) since 1500. The data reveal that despite the severity of the Millennium Drought, the five worst single years of drought happened before 1900. But 2011 was the wettest year in our 513-year record. The dominant theme of Australia’s drought history is variability. We may get one year of extremely wet conditions (for example in 2011) or we might get six years of extremely dry conditions (such as 2003-2009). North Queensland may be flooded out while Victoria suffers with drought. Or in extreme circumstances, the entir...

The Tropics and the Furious Fifties

There’s an old sailor’s expression: “Below 40 degrees south there is no law, below 50 degrees south there is no God.” Since the sixteenth century, sailors have spoken in awe of the violent westerly winds and seas they experienced fighting their way across the Southern Ocean. With few landmasses to slow them down, the winds found across 40 degrees latitude often reach speeds of twenty-five knots—about 40 percent stronger than their northern hemisphere counterparts—earning them the title the “roaring forties.” As shipping pushed farther south, explorers realized that these winds form part of a vast storm belt that includes the “furious fifties” and “screaming sixties,” names more reminiscent of terrible rock bands than a major part of our planet’s circulation system. The early hunters and traders didn’t understand it at the time, but these winds are created by a procession of low-pressure systems carried east by the jet stream, a river of cold air hurtling and twisting round the Antarct...

Death of a colony

Cape Denison holds a special place in the history of Antarctic exploration. A small outcrop of rocks on the remote East Antarctic coastline, Cape Denison is forever associated with one of the most spectacular and often forgotten tales of survival. A century ago it was the main base of operations for one of the great explorers of the south: the Australian scientist Sir Douglas Mawson . Privately funded, three bases and one research ship supported a science team that explored a region the size of the United States between 1911 and 1914. Mawson’s Australasian Antarctic Expedition, however, suffered terribly during their time at Cape Denison: a sudden turn of events led to tragedy on the ice, the death of two men, allegations of cannibalism and with the return of winter sea ice, an extended stay in Antarctica. But when they first came upon Cape Denison, Mawson was ecstatic. Greeted by squawking penguins: ‘ We were soon inside a beautiful, miniature harbour completely land-locked. The su...
