6 October 2016, The Conversation, Paris climate agreement comes into force: now time for Australia to step up. The Paris climate agreement is set to enter into force next month after the European Union and Canada ratified the agreement overnight. The agreement, reached last December, required ratification by at least 55 countries accounting for 55% of global emissions to become operational. 

Why has ratification been so quick? The optimists would point to this as evidence of mounting international momentum. A truly global agreement and joint ratification by China and the US have reinvigorated international efforts. India, Canada and the EU have followed shortly after the US and China. Canada also recently announced a domestic carbon tax of C$10. Ratification is not action per se, though, and it’s difficult to directly link the domestic actions of Canada and others to Paris. The more realistic explanation for the ratification landslide is less inspiring. The Paris Agreement is so weak in terms of legal obligations that countries have little reason not to ratify it. The legal obligations of the Paris Agreement are sparse and procedural. Countries are bound to submit increasingly stringent pledges every five years. Yet they are not obliged to achieve them.

What about Australian ratification? Australia has yet to ratify the Paris Agreement, but will likely do so soon. Australian ratification of international treaties is done through the executive, not the parliament. Prime Minister Turnbull makes the final decision as to whether Australia will ratify the Paris Agreement. Turnbull will not act alone; his decision will be advised by cabinet and the report of the Joint Standing Committee on Treaties (JSCOT). This is a cross-party committee made up of members from the Senate and the House of Representatives. JSCOT is considering the Paris Agreement and will hold its final public briefing in Melbourne today. Shortly thereafter it will report back to parliament. Given that Paris implies few obligations, Australia will likely ratify the agreement before the end of the year. Not doing so would unnecessarily risk Australia’s already tattered reputation on climate change. Yet there are also fears that Australia risks embarrassment by ratifying and then missing its first pledge.

Target troubles: Currently, Australia has made an intended nationally determined contribution (INDC) to reduce emissions by 26-28% on 2005 levels by 2030. If Australia joins the Paris Agreement this would likely become our first pledge under the deal. But existing modelling suggests we will significantly overshoot this target.Climate Action Tracker estimates that Australia is instead on track to increase emissions above 27% on 2005 levels by 2030 (this equates to 61% above 1990 levels). They note: “Australia stands out as having the largest relative gap between current policy projections for 2030 and the INDC target.” Read More here

6 October 2016, Climate News Network, Climate treaty races towards hazy future. The far-reaching Paris Agreement on tackling climate change is close to taking effect − but how just how effective it may prove is far from clear. With a speed almost unknown in the annals of diplomacy, the Paris Agreement on climate change is ready to come into force a bare 11 months after it was reached on 12 December last year. Its ratification by the European Union means the world will have crossed both thresholds necessary for the Agreement to enter into force within 30 days. …It’s too early either to make so sweeping a claim or to write off Paris as a well-meaning attempt that was too little and too late. But the reality the Agreement has to tackle is daunting. For instance, the targets identified in Paris may have been seriously inadequate. We may already be much closer to exceeding the safety level for emissions than we realise, and there is still no guarantee that trapping and storing emitted carbon dioxide would work, although it is judged to be an essential technology for Paris to succeed. And some scientists say the world will have to switch to renewable energy far faster than we are doing at the moment for the Paris Agreement to have a chance of working. With a list of challenges like these, it would be premature to start celebrating the Agreement’s entry into force just yet. Dr Niklas Höhne, a founding partner of the NewClimate Institute for Climate Policy and Global Sustainability, spoke for many when he said: “With the entry into force of the Paris Agreement, the work is only just beginning. “For 1.5°C in particular, the window of opportunity is closing rapidly. Waiting until 2018, when the next round of revised national proposals are expected to be presented, will be too late.” Read More here

29 September 2016, The Conversation, Record high to record low: what on earth is happening to Antarctica’s sea ice? 2016 continues to be a momentous year for Australia’s climate, on track to be the new hottest year on record. To our south, Antarctica has also just broken a new climate record, with record low winter sea ice. After a peak of 18.5 million square kilometres in late August, sea ice began retreating about a month ahead of schedule and has been setting daily low records through most of September. It may not seem unusual in a warming world to hear that Antarctica’s sea ice – the ice that forms each winter as the surface layer of the ocean freezes – is reducing. But this year’s record low comes hot on the heels of record high sea ice just two years ago. Overall, Antarctica’s sea ice has been growing, not shrinking. So how should we interpret this apparent backflip? In our paper published today in Nature Climate Change we review the latest science on Antarctica’s climate, and why it seems so confusing. Antarctic surprises. First up, Antarctic climate records are seriously short. The International Geophysical Year in 1957/58 marked the start of many sustained scientific efforts in Antarctica, including regular weather readings at research bases. These bases are mostly found on the more accessible parts of Antarctica’s coast, and so the network – while incredibly valuable – leaves vast areas of the continent and surrounding oceans without any data. In the end, it took the arrival of satellite monitoring in the 1979 to deliver surface climate information covering all of Antarctica and the Southern Ocean. What scientists have observed since has been surprising. Read More here

5 October 2016, The Conversation, Lessons from South Australia’s blackout: we need to make infrastructure more resilient to climate change. Last week’s storm and subsequent state-wide blackout in South Australia reminds us how important the electricity grid – and other infrastructure – is for our communities. Immediate analysis suggests the blackout was caused by the collapse of transmission infrastructure in South Australia. Australian electricity networks, like most transmission networks worldwide, rely on above-ground conducting wires held aloft by large towers. Some of these towers were blown over in the South Australian event. While the storm hasn’t yet been specifically linked to climate change, it also serves as a reminder of the increasing challenges of delivering essential services in a more variable climate and slowing economy. Power, water, transport, health, defence and communications infrastructure can be exposed to climate variability and change simply because of their long lifetimes. Therefore, many if not most owners and operators of essential infrastructure have commissioned climate vulnerability and adaptation studies. There are many good examples of adaptation. For instance, Queensland Urban Utilities, the major water distributor and retailer in south-east Queensland, is implementing a large program to make the water and wastewater delivery network more resilient to flooding. But there is increasing recognition among climate adaptation researchers that many of the recommendations from climate adaptation studies aren’t being adopted. This is sometimes referred to as the “plan and forget” approach to climate adaptation and it leaves critical infrastructure vulnerable to weather extremes. Read More here
