From the science of greenhouse gases to the intricate logic of cap and trade, Broome reveals how the principles that underlie everyday decision making also provide simple and effective ideas for confronting climate change. Climate Matters is an essential contribution to one of the paramount issues of our time.

Author Deb Hunt sets out to discover what makes our Australian farming families tick. Travelling to properties across the country - from a vast, dusty cattle run in outback Queensland to the wheat belt of Western Australia and dairy farms in Tasmania - and introducing us to eight different families who survive and thrive on the land, these stories provide a window into a way of life that defines the Australian spirit at its best.

On March 11, 2011, an earthquake large enough to knock the earth from its axis sent a massive tsunami speeding toward the Japanese coast and the aging and vulnerable Fukushima Daiichi nuclear power reactors. Over the following weeks, the world watched in horror as a natural disaster became a man-made catastrophe: fail-safes failed, cooling systems shut down, nuclear rods melted.

How serious are the threats to our environment? Here is one measure of the problem: if we continue to do exactly what we are doing, with no growth in the human population or the world economy, the world in the latter part of this century will be unfit to live in. Of course human activities are not holding at current levels—they are accelerating, dramatically—and so, too, is the pace of climate disruption, biotic impoverishment, and toxification.

The industrial age made possible by fossil fuels will surely decline as these fuels run out. In The Ecotechnic Future John Michael Greer alerts the listener to possible changes future generations may face as these dwindling fuel supplies lead first to a deindustrial age, then to a society which salvages the remnants of our current plenty, and eventually to a time in which people may learn to live in balance with the environment: an ecotechnic society.

Coming home from the war in Iraq, US Army private Roy Scranton thought he'd left the world of strife behind. Then he watched as new calamities struck America, heralding a threat far more dangerous than ISIS or al-Qaeda: Hurricane Katrina, Superstorm Sandy, megadrought - the shock and awe of global warming. Our world is changing. Rising seas, spiking temperatures, and extreme weather imperil global infrastructure, crops, and water supplies. Conflict, famine, plagues, and riots menace from every quarter.

The Hunter River is the lifeblood of the Hunter Valley. But since early settlement it hasn't been treated like a life blood; it has been exploited, turned into a dumping ground and over-run by weeds. In 2001, ABC Newcastle's Phil Ashley-Brown interviewed people along the 470km Hunter River between Barrington Tops and Newcastle Harbour. In 2003 the series highlighted the poor state of the waterway and tapped into a passion that many people have for the Hunter River. In 2011 Phil went back to the river to see how much change there has been over the last 10 years.

What's causing our current high food prices? Is organic food really better for us? Do we care about Fairtrade or food miles? Should we buy locally or from the supermarket?

Eating has been described as the "most political act we do on a daily basis", with our choices affecting our health, landscape, climate, and economy. Food: What Are We Really Eating? lifts the lid on food production and the dizzying array of food choices we face each time we shop.

He explains the idea of “Cradle to Cradle”, and how humans can become tools of the natural world once more. He explores the difference between a consumer and a customer, explains what is meant by accruing a “materials bank”, and proposes how we can turn sewage treatment plants into nutrient management plants. He is an anticipatory design architect. But more than that he is a philosopher for the 21st century, and is asking some of the most critical questions we should be thinking about in these challenging times.
