The latest UN climate report makes it clear that the task of limiting climate change is urgent and huge. We must start to transform our economy today, but it will bring rewards as well as challenges.
The world needs to be carbon-neutral by mid-century to give ourselves a chance of holding global warming to 1.5C. With around 1% of the global carbon budget, Australia needs to rapidly do its share.
The late Sen. John McCain was an early – and lonely – Republican supporter of action to fight climate change. His challenge was to regulate sources of energy that underlie much of our economy.
Renewable energy investment is gathering steam throughout the world. Australia's National Energy Guarantee policy should be made agile enough to jump on board, because this runaway train won't stop.
The National Energy Guarantee faces a crunch test this week. And if the climate wars of the past few decades are any guide, Australian policies more often sink than swim when the waters get choppy.
Richer countries import products but not the emissions used to make them.
The first IPCC conference on cities has highlighted the challenges of reconciling science, urban practices and politics. But it was an important recognition of cities' leading role in climate action.
Australia's flagship climate policy, has spent more than $2 billion on emissions reductions, yet big businesses could wipe all this out. Time to resurrect the idea of a simple carbon tax.
The federal government's keenly awaited review of Australia's climate policies continues a longstanding bipartisan traditional of weak policy development in this area.
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.
The Turnbull government is still tying itself in knots over the future of coal, as literally decades of policy turmoil on climate and energy continue to roll on.
It's a good thing that cities aspire to lead the way in acting on climate change in the absence of stronger national action. But a closer look reveals the limitations of current city-based efforts.
A new analysis by ClimateWorks Australia says that the electricity sector needs to do far more to cut its carbon emissions than will be delivered by current policies.
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.
Diesel engines have been demonised for their emissions but the technology has already cleaned up its act.
With Donald Trump overturning Obama's Clean Power Plan, and some Australian politicians cheering him on, will we always have Paris?
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.
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?
This week's Pacific Islands Forum is the region's premier multilateral summit. But members have begun turning elsewhere out of frustration with Australia's climate negotiation tactics.
Unlike the Kyoto Protocol, which languished for years, the Paris climate agreement is rocketing towards the threshold for it to enter into international law – leaving Australia in its wake.
