The Greens have successfully cast themselves as the party of climate science. But to hit their climate goals they may need to become even more radical, by embracing technologies like nuclear power.
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.

What gaps have the CSIRO cuts left in climate research?
Was Labor’s shadow environment minister, Mark Butler, right to say Australia was ‘pretty much’ the only major advanced economies where greenhouse pollution levels are going up?
Labor's shadow environment minister, Mark Butler, said Australia is now "pretty much the only major advanced economy where pollution levels are going up, not coming down." Is that right?

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.
Tasmania’s Cape Grim monitoring station passed a crucial carbon dioxide threshold this month.
