A singular focus on divestment from oil and gas companies to counter climate change could be detrimental.
The broad principle of companies, government bodies and universities divesting from oil, gas and coal companies is sound. But its application needs more sophistication.
Wasting food, wasting the earth.
Feeding Melbourne generates over 900,000 tonnes of edible food waste every year, enough to feed more than 2 million people.

What gaps have the CSIRO cuts left in climate research?
The dairy industry faces a number of welfare and environmental issues.

The dairy industry faces a number of welfare issues, and is a major contributor to greenhouse gases.
Glacier melt is one of the major contributors to global sea level rise.

Global average sea level has risen by about 17 cm between 1900 and 2005, but we didn't know how much of that was due to us, until now.
Livestock ‘digestion’ produces nearly 3 billion tonnes of greenhouse gases each year.

Eating less meat isn't the only solution to reducing greenhouse gas emissions from livestock.
Rice cultivation is one of the ways food production pumps methane into the atmosphere.

Fossil fuel emissions are slowing, but another major climate problem is becoming clear: food production.
So much water has gone into groundwater it has slowed rising seas.

There's enough water under the ground to form a lake 100m deep over the earth.
Leaders celebrate the adoption of the Paris Agreement on Saturday.
The Paris Agreement is an extraordinary achievement. But there is much work to be done to ensure global warming does not exceed dangerous levels.
Coal mines are increasingly incompatible with the world’s carbon budget.
The Paris climate agreement doesn't specifically address cutting down on coal, but the tide is turning against coal mining anyway.
Businesses that emit large amounts of greenhouse gases will have their emissions capped.
Australia's new cap on emissions includes aspects of a "baseline and credit" emissions trading scheme. That's cheaper for businesses, but means more regulation.
Climate costs can seem scary, but it’s all in how you look at them.

Is ambitious action on climate change a recipe for a significant hit to the economy and our living standards?
Business, environmental, trade union and social groups all see advantages in looking beyond high-emission industries such as coal-fired power.

The Australian Climate Roundtable unites business, environmental and social groups in calling for a strong climate policy. This unprecedented show of unity might even break down Canberra's climate stalemate.
What happens to coal in China will play a big role in deciding which climate road we’re all on.

Peak fossil fuel means it's unlikely the worst climate scenario will come to pass. Gary Ellem explains.
The face of climate evil, or just a juicy steak?
Going vegetarian might help reduce your personal footprint - but it won't save the climate. Richard Eckard explains.
To find out if the carbon price worked, you have to look at the electricity sector.
Emissions fell by six times the rate in the five years before the carbon tax than they did under the carbon tax. – Environment minister Greg Hunt, The Guardian, January 17, 2015. Australia’s total greenhouse…
The Western Treatment Plant in Werribee, Victoria, largely powers itself using biogas – a by-product of sewage treatment.

Could what we flush down the toilet be used to power our homes? Thanks to biogas technology, Australia’s relationship with organic waste – human and animal excreta, plant scraps and food-processing waste…
Australian farmers apply nearly a million tonnes of nitrogen-based fertilisers every year.
When we talk about greenhouse gases we usually talk about carbon dioxide. When media reports depict climate change, we invariably see the cooling towers of a coal power station. Which is fair, because…
To match the US, Australia would have to increase its emissions reduction target to 25% below 2000 levels.

*If you use the full Kyoto period — 1990 to 2020 — the US is minus 5% and Australia is almost exactly the same. * Environment minister Greg Hunt, Radio National, November 17. *We and the United States…
Planes and airports both have big carbon footprints – and the sector is still growing.
No matter what the aviation industry does to reduce emissions, it will be outweighed by growth in air travel, according to a new analysis. Growth will trump emissions cuts even if significant (and contentious…
