The heat is on: BOM launches heatwave forecasting


BOM heatwave forecast
Just as a record-breaking heatwave was moving eastwards from Western Australia last week, the Bureau of Meteorology (BOM) launched a trial heatwave forecast service. The forecast shows, up to four days in advance, which areas of Australia can anticipate heatwaves. But are heatwave warnings even necessary for “a sunburnt country” with a history of long, hot summers?

Chronology of climate change in Australia

The Parliamentary Library has published a timeline of climate policy in Australia. The chronology begins in the 1970s, around the time that the Australian Academy of Sciences published a report asserting that human activities are likely to contribute to warming. The document charts the journey of Australian climate policy from then until today.

Stronger targets proposed in Climate Change Authority draft report


Image source: Climate Change Authority
Today the Climate Change Authority (CCA) released a draft version of its ‘Targets and Progress Review’. The review, which according to the Clean Energy Act 2011 must be finalised by 28 February 2014, is to be used by the Minister in determining Australia’s emissions reduction goals under the carbon price mechanism. The draft report proposes two sets of caps; each set of caps defines a different emissions trajectory between now and 2020, and then to 2030. The CCA is calling for stakeholder input until 29 November 2013.

What the latest IPCC report says about Australia

Image source: CAWCR
Since the 1900s the world has warmed an average of 0.85 degrees and the sea has risen an average of 19 cm. So affirms the 2,216-page draft report of the Intergovernmental Panel on Climate Change (IPCC) released on 27 September 2013 (see separate FlagPost on the IPCC). The first instalment of the IPCC’s Fifth Assessment Report (AR5) presents the latest science on global climate change. But Australia has a unique climate, influenced by both Indian Ocean events and the highly variable El NiƱo Southern Oscillation (ENSO) phenomenon. What does the latest IPCC report say about Australia?

What is the Intergovernmental Panel on Climate Change and how does it work?

Image source: CAWCR
The Intergovernmental Panel on Climate Change (IPCC) released on 27 September the first instalment of its eagerly anticipated Fifth Assessment Report (AR5). As with past reports, this one is likely to spark ongoing discussion about the threat from climate change and how to deal with it. But what is the IPCC and what exactly does it do?

Countries trading greenhouse gas emissions

Over the last three years, the global carbon market has more than doubled in volume but almost halved in value. In that time a further eight countries, states or cities have adopted a carbon market as their primary means for reducing greenhouse gas emissions. Yet the price for one tonne of carbon dioxide equivalent has dropped by as much as 100 per cent in some markets.

A new paper from the Parliamentary Library provides a basic overview of the size and value of the global carbon market and details exactly which countries and regions are covered by a mandatory emissions trading scheme (ETS). Here is a snapshot of that paper.

Latest US climate Bill follows Australian lead

The US seems to be following in the footsteps of Australia, at least in terms of climate policy. Last week, Senators Sanders and Boxer introduced into Congress a Bill that establishes a carbon price. Like Australia’s Clean Energy Act, the US’s proposed Climate Protection Act would see the majority of carbon tax revenue flowing back to households to assist with rising energy prices. Also proposed, and comparable to Australia’s Clean Energy Finance Corporation, is a $500 billion program to co-invest in, or provide guarantees for, energy efficiency and renewable energy projects.

Introducing the Doha Climate Gateway



Image source: COP18 website
On 8 December 2012—a day later than scheduled—the 18th Conference of the Parties (COP18) to the United Nations Framework Convention on Climate Change (UNFCCC) concluded. With it, ended the Bali Roadmap (see previous FlagPost) and began the new era of climate change negotiations: that of the grandly-named Doha Climate Gateway. This FlagPost describes what the Gateway opens onto, and outlines some other items that were discussed (although possibly not resolved) at Doha.

What happened to Kyoto at Doha

Image source: COP18 website
The latest international climate change negotiations that took place over the last fortnight in Doha, Qatar, marked the end of the Bali Roadmap. This 18th Conference of the Parties (COP18) to the United Nations Framework Convention on Climate Change finally signed off on the climate change action plan that had been in place since negotiations in 2007. Coming into Doha there were two main negotiating streams: one that discussed the Kyoto Protocol and how to extend it beyond its expiry on 31 December 2012, and another that looked beyond the Kyoto Protocol to a broader, more inclusive agreement. This FlagPost will outline developments on the first stream. A second FlagPost addresses the other stream.

Trading aviation emissions – Part 3: Australia outlines its position

Image source: Wikimedia Commons
The Government yesterday announced solidarity with a number of other countries opposing the EU’s move to include international aviation in its emission trading scheme. The motion was originally put forward by Nationals Leader Warren Truss who has been active in raising awareness on the issue. The Government supported Mr Truss’ motion. Two previous FlagPosts (this one and this one) outline why the EU's decision has been controversial and what reactions there have been. This FlagPost summarises Australia’s position and provides an update on international actions.

Parliamentary debates on the Greenhouse and Energy Minimum Standards (GEMS) Bill have been deferred. The Bill was originally scheduled for discussion on Thursday 28 June, with the portfolio Shadow Minister to outline the Coalition’s position. Although the scheme started out as a Labor election promise in 2007, it evolved into a commitment under COAG’s National Strategy on Energy Efficiency to ‘establish national legislation for Minimum Energy Performance Standards (MEPS) and labelling, and over time move to add Greenhouse and Energy Minimum Standards (GEMS)’. This Bill implements that COAG commitment.

Legislation for a mandatory greenhouse gas emissions trading scheme (ETS) has passed South Korea's unicameral National Assembly with bipartisan support. However, many important details have still to be finalised. This FlagPost provides a summary of the Korean scheme with a little bit of background.

Trading aviation emissions - Part 2

Image source: Department of Infrastructure and Transport
The leader of the Nationals, Warren Truss, has called the EU's inclusion of aviation in its emission trading scheme (ETS) an 'iniquitous tax', siding with a number of countries that oppose the move. In its FlagPost Trading aviation emissions from February, the Parliamentary Library outlined the main elements of the EU's decision and some of the international relations issues that have arisen. Since then, a series of new developments have taken place and the debate is far from resolved. This FlagPost is an update on the situation globally.

Australia's big wet: La NiƱa explained

The Bureau of Meteorology, the CSIRO, and the World Meteorological Organisation have each released a review of Australian and world climate in 2011. According to these three sources, 2011 in Australia was generally cooler than recent years...but warm for a La NiƱa year. It was also a wet year for Australia...but then, that’s normal for a La NiƱa year. So what is La NiƱa? How do we understand climate change and variability in the context of a La NiƱa event?

The sun sets on solar hot water rebates

Image source: yourhome.gov.au
The Government has ended its solar hot water rebate initiative, the Renewable Energy Bonus Scheme (REBS). An announcement was made yesterday that henceforth REBS rebates will only be eligible to those people who have had systems installed, ordered or purchased before 28 February 2012, and lodged a claim before 30 June 2012. Although the scheme was always meant to end on 30 June 2012, this is the first time a purchase cut-off date has been publicised. Besides providing prospective applicants with no prior warning, the closure raises the question of why has the rebate been phased out so suddenly?

Global Warming and Coral

Image source: Australian Government
There are two reasons why scientists have long been concerned about the effects of climate change on coral reefs. Firstly, corals will only grow in a narrow range of water temperatures. Secondly, when there is more carbon dioxide in the air, more of the gas dissolves into the sea. When carbon dioxide dissolves in water, it makes the water slightly more acidic, and this change in chemistry is likely to make it more difficult for corals to build reefs.

While the growth rate of most marine organisms usually increases with warmer water temperature, it had always been thought that many corals are damaged by small increases in maximum water temperatures. On average, global sea surface temperatures (known as SSTs) have increased over the past century but, surprisingly, there have been different responses to this change from the corals on Australia’s west coast and in the east. A 2012 study , just released, has found that coral calcification rates of reefs in higher latitudes of Western Australia have significantly increased over the past century despite rapidly rising SSTs. On the other hand, a 2009 study found that coral calcification rates along the entire Great Barrier Reef (GBR) declined over the period 1990-2005.

Trading aviation emissions

Image source: Department of Infrastructure
For the first time, Qantas and other airlines are being held accountable for greenhouse gas emissions from their international flights—at least for those flights using an airport within the European Union (EU). The move by the EU to price and restrict greenhouse gas emissions from European flights has been a contentious one. This FlagPost explains the basic mechanics of the EU’s decision and highlights some of the issues being raised.

Carbon Pricing Mechanism—editorials and opinion pieces

Image source: National Library of Australia
For easy access to commentary on the Carbon Pricing Mechanism, the Parliamentary Library has prepared a page of press editorials and opinion pieces following the Government’s announcement of its Clean Energy Plan on Sunday 10 July 2011. The page covers the week following the announcement, that is, from Monday 12 July 2011 to Friday 15 July 2011, and contains newspapers representing all the states and territories. The press editorial and opinion pieces page and other information on the Carbon Pricing Mechanism are available on the Parliamentary Library's climate change website.
The press editorials and opinion pieces page is only available to Senators and Members and their staff. The Parliamentary Library's climate change website and briefs on the Carbon Pricing Mechanism are available to the general public.

To assist comparison of the previous Carbon Pollution Reduction Scheme and the proposed Carbon Pricing Mechanism, the Parliamentary Library has prepared a table of selected features from each scheme. The table shows side-by-side the architecture of each scheme in relation to coverage, caps, permit prices, international linkages, impact on the Budget, household and industry assistance and compensation, and more. Other briefs on the Carbon Pricing Mechanism are available from the Parliamentary Library's climate change website.

Carbon Pricing Mechanism—Which 500 companies pay the tax?

Image source: NSW Government
The Government has been clear that only Australia’s 500 biggest ‘carbon polluters’ will be directly affected by the proposed Carbon Pricing Mechanism (CPM). This is down from the 1000 that would have been liable under the previous Carbon Pollution Reduction Scheme, mainly due to the exclusion of fuels from the CPM. There has been some speculation as to which companies would be included in the Government’s list of 500, and which ones are Australia’s ‘top 50 carbon polluters’. The Parliamentary Library has published a short brief with some information on determining which corporations are likely to be included, and an explanation on why a definite list of 500 companies is not publicly available.
