Sharks: playing their part in reducing climate change.
Poor management of the oceans, including the killing of crucial marine predators, could result in more greenhouse gasses.
While action on air pollution is welcome, there may be better ways to cut car emissions.

The Australian Renewable Energy Agency has survived, amid a groundswell of domestic and overseas support. Its budget has been chopped, but here's how it can still drive the renewable energy revolution.
The Climate Change Authority’s latest report has divided its membership.
Two members of the Climate Change Authority offer an alternative view on its latest report, arguing that the recommendations are not in line with Australia's international climate obligations.

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.
Scorching temperatures in Jammu, northern India. This month has seen records smashed in nearby Rajasthan.
The city of Phalodi has set a temperature record for India, hitting 51℃. Until now, India's smog problem has curbed extreme temperatures. But that could be about to change.

The dairy industry faces a number of welfare issues, and is a major contributor to greenhouse gases.
We need a global target for reducing emissions in agriculture to meet the Paris Agreement. Farmers have an opportunity to help meet the 2 degree C target in the Paris Agreement, but known practices will not be enough.
To meet global climate change targets, agriculture needs an array of innovations and money to get farmers around the world to adopt new practices.
