The window for staving off the worst of climate change is wider than we thought, but still pretty narrow.
It's still possible to hit the more ambitious of the two Paris global warming goals, according to a new estimate of the global carbon budget. But it sure won't be easy, and we need to start now.
So large are the nation’s daily greenhouse gas emissions that if yours is a typical Australian lifestyle you’re contributing disproportionately to climate change.
It would take a lifestyle upheaval to drop most Australians' household emissions to a sustainable level. Even many of us who urge equitable action on climate change act as if this doesn't apply to us.
Tonight on the ABC's Catalyst, scientist Tim Flannery asks if seaweed can save the world. It's a bold claim for algae, but seaweed could play a key role in keeping climate change in check.
Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Depending on the policy settings, a low-emissions target could conceivably award carbon credits to coal plants.

The Finkel Review looks likely to recommend a "low emissions target", which would award credits to cleaner energy sources, much like the current Renewable Energy Target.
Are drones the parcel couriers of the future?
Online shopping giants and logistics firms are trying to improve efficiency and cut carbon – knowing that doing so will reduce their operating costs while appealing to green-minded consumers.
Heavy industry still seems reluctant to engage with the Emissions Reduction Fund.

A survey of executives in high-emitting industries such as mining and electricity generation suggests they are not engaging with the government's flagship policy to cut greenhouse emissions.
Has carbon capture and storage been tarnished by its association with the coal industry?

Carbon capture and storage gets a bad rap from its associations with 'clean coal'. But the technology could prove vital in cutting emissions from other industries like steel, cement and chemicals.
Hazelwood in happier times.
Centre for Gippsland Studies
Hazelwood power station will this week fall silent after a half-century during which it went from a beacon of progress to an emblem of fossil fuel pollution.
Wave goodbye to US climate leadership.
Donald Trump has signalled the end of US leadership on climate policy, with potentially unpleasant consequences for America's economy, security and diplomatic standing.

Leaders are worried US leadership on global issues like climate change will be diminished under President Trump. Experts explain why China is ready to lead, and how that could be a good thing.
Upgrading our fuel rules can deliver some easy wins for emissions.

Australia's plan to bring fuel efficiency standards up to par with the US and Europe could see us say goodbye to regular unleaded, and hello to a useful way of cutting our rising greenhouse emissions.
Chinese President Xi Jinping and his French counterpart François Hollande can help to drive global climate action.
If Donald Trump turns away from climate action as George W. Bush did, Europe and China can respond by forming an alliance that will turn the United States from a climate leader into a follower.
Aviation emissions are growing about 5% each year.

An international meeting looks set to approve a mandatory system of carbon offsetting for international flights - a big step forward but one that might be hard to integrate with the Paris Agreement.
Yallourn Power Station in the Latrobe Valley is one of the emissions intensive power stations that remains open.

Environment and energy minister Josh Frydenberg said that eight out of Australia's 12 most emission intensive power stations closed in the last five years. Is that right?
With the right help, ARENA can help deliver many more solar farms.

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.
Nne-star-rated ‘Catalyst’ houses built to maximise passive solar principles were evaluated against seven control houses built to DHHS standards.
Emerging research challenges the idea that sustainable housing is unaffordable. It shows sustainability and good design can be affordable when analyses include social, health and wellbeing benefits.
CSIRO has the know-how to develop commercial-scale green energy, with a clear plan and enough money.
The Coalition has asked CSIRO to develop a "roadmap" towards commercialised clean energy. It's a good idea as long as the plan is clear, and there's enough money behind it.
Would you pay an extra couple of dollars for the climate?
A carbon tax on airline tickets might sound like a tricky sell, but many airlines already collect a similar levy to raise funds for developing world health initiatives.
Is the sun setting on coal investments?
Energy companies are realising that, in light of the Paris climate deal, the economics are starting to line up in favour of climate action, not against it.
