Malcolm Turnbull would be no better than Abbott on Climate Change

Map-Abbott-climateCoalition needs a heart transplant, not a facelift, The Age,  . 6 Feb 15 The public has been focused on policy and that’s precisely why the Coalition’s in trouble. “…..the government’s in trouble precisely because we have been focussing on policy.

That was true for Labor, whose collapse in public support occurred the moment Kevin Rudd decided he no longer thought climate change mattered that much, and it is perhaps even truer for Abbott…..”http://www.smh.com.au/comment/coalition-needs-a-heart-transplant-not-a-facelift-20150205-136hjx.html

Here’s how Mark Kenny &  James Massola saw it, writing in The Age 5 February 15 –  “Amid feverish speculation over the leadership, unconfirmed reports also claimed Mr Turnbull had moved to assuage fears in the conservative wing of the party that his return to the leadership would see a reprise of the carbon tax or an emissions trading scheme.

It was claimed Mr Turnbull had promised, in a secret deal, that there would be no such reprise if elected”

Warming of Southern Oceans

ocean-heatingSouthern oceans play major role in absorbing world’s excess heat, study finds February 3,  Environment Editor, The Sydney Morning Herald The world’s oceans are heating at the rate of two trillion 100-watt light bulbs burning continuously, providing a clear signal of global warming, according to new study assessing data from a global fleet of drifting floats.

The research, published on Tuesday in the journal Nature Climate Change, used data collected from the array of about 3500 Argo buoys from 2006-13 to show temperatures were warming at about 0.005 degrees a year down to a depth of 500 metres and 0.002 degrees between 500-2000 metres.

Oceans south of the 20-degree latitude accounted for two-thirds to 98 per cent of the heat gain during the period studied, with three giant gyres in the southern Pacific, Indian and Atlantic oceans largely responsible for drawing down the extra warmth.

“The global ocean heat content right now is the most reliable metric of that radiation imbalance” between the energy received from the sun and what is radiated back to space, said Susan Wijffels, an oceans expert at the CSIRO and one of the report’s authors………..

“The ocean is just vertically transferring the heat away from the surface to the depth,” Dr Wijffels said. “The ‘hiatus’ is not meaningful.”

Even with the relative slowdown in surface temperature increases, 14 of the world’s 15 warmest years on record have been in the 21st century, the World Meteorological Organisation said on Monday.

The United Nations body also confirmed that 2014 was the hottest year, edging out 2010 and 2005. The readings were based in part on United States agencies, including NASA which last month also declared 2014 as its warmest year.

John Church, another of the paper’s authors and also from the CSIRO, said the temperatures in the atmosphere – which accounts for just 1 per cent of the planet’s heat uptake – would rise sharply if oceans absorbed less of the heat……..

As it is, warming oceans are swelling in volume, lifting sea levels, and also affecting ecosystems, he said.

“If we want to avoid the worst impacts of climate change then we need to start taking some mitigation action,” Dr Church said. This included cutting carbon emissions and lifting renewable energy targets at home and overseas.

Future Argo missions will extend coverage to higher latitudes, including sea-ice zones, and reach depths of 6000 metres.

However, Dr Wijffels said Australia’s contribution is in doubt with about half of its Argo budget tied up with the Abbott government’s stalled higher education reform bills.  Those funds run out “in a few months”, she said.

The Nature study was led by Dean Roemmich of the California-based Scripps Institution of Oceanography. http://www.smh.com.au/environment/climate-change/southern-oceans-play-major-role-in-absorbing-worlds-excess-heat-study-finds-20150202-133j2p.html

CSIRO Report on Climate Change in Australia

climate-changeClimate change in Australia http://apo.org.au/research/climate-change-australia

Penny Whetton

27 January 2015

highly-recommendedCSIRO and the Bureau of Meteorology have released climate change projections for Australia that provide updated national and regional information on how the climate may change to the end of the 21st century.

The projections are the most comprehensive ever released for Australia and have been prepared with an emphasis on informing impact assessment and planning in the natural resource management sector. Material has been drawn from observations and from simulations based on up to 40 global climate models and four scenarios of greenhouse gas and aerosol emissions during the 21st century.

The 2015 projections provide greater levels of detail and confidence compared to previous projections. Findings are consistent with previous projections research and analysis for Australia, and incorporate an increased knowledge base.

The new climate change projections for Australia are funded by the Department of the Environment through the NRM Planning for Climate Change Fund with co-funding from CSIRO and the Bureau of Meteorology.

The Technical Report is intended to provide detailed information for researchers and decision makers. It is a comprehensive report outlining the key climate change projection messages for Australia across a range of variables. The report underpins all information found in other products, including this website. It contains an extensive set of figures and descriptions on recent Australian climate trends, global climate change science, climate model evaluation processes, modelling methodologies and downscaling approaches. The report includes a chapter describing how to use climate change data in impact assessment and adaptation planning.

Key findings

Overarching findings

Australia’s climate has already changed.

  1. It has become hotter since 1910, with warming across Australia of 0.9°C
  2. Rainfall has increased in northern Australia since the 1970s and decreased in south-east and south-west Australia
  3. More of Australia’s rain has come from heavy falls and there has been more extreme fire weather in southern and eastern Australia since the 1970s.
  4. Sea levels have risen by approximately 20cm since 1900.

Projections for Australia’s future climate vary regionally and depend on which of the four greenhouse gas and aerosol emissions scenarios is considered. Overarching findings include:

  1. Australia’s average temperature will increase and we will experience more heat extremes and fewer cold extremes.
  2. Extreme rainfall events that lead to flooding are likely to become more intense.
  3. The number of tropical cyclones is projected to decrease but they may be more intense and reach further south.
  4. Southern and eastern Australia is projected to experience harsher fire weather.
  5. Sea levels will continue to rise throughout the 21st century and beyond.
  6. Oceans around Australia will warm and become more acidic.

Additional findings

Temperature

  1. Australian average temperature has increased by 0.9° C since 1910.
    1. We have seen more hot days and less cold days.
  2. Temperatures will continue to increase over the 21st century.
    1. The extent of those increases will depend on global emissions of greenhouse gases and aerosols.
  3. By late in the century (2090), Australian average temperature is projected to increase by 0.6 to 1.7°C for a low emission scenario, or 2.8 to 5.1°C under a high emission scenario.
    1. Hot days are projected to occur more frequently while there will be fewer frost days.

Rainfall

  1. Winter and spring rainfall in southern Australia is projected to decline while changes in other areas are uncertain.
  2. For the rest of Australia, natural climate variability will predominate over rainfall trends caused by increasing greenhouse gases until 2030. By 2090, a winter rainfall decrease is expected in eastern Australia.
  3. Overall, extreme rain events are projected to become more intense.
    1. This finding is consistent across Australia even in areas where average rainfall is projected to decrease or the average direction of change is uncertain. This is largely due to the ability of a warmer atmosphere to hold more water.
  4. However, the projected reduction in average rainfall in south-west Western Australia may be so strong as to weaken this extreme rainfall tendency.

Drought

  1. The time in drought will increase over southern Australia, with a greater frequency of severe droughts.
  2. The time in drought and the frequency of extreme droughts may increase elsewhere in Australia.
  3. A projected increase in evaporation rates will contribute to a reduction in soil moisture across Australia.

Tropical cyclones

  1. Tropical cyclones may occur less often; however they will likely be more intense.

Snow

  1. There will be a decrease in snowfall, an increase in snowmelt and thus reduced snow cover.

Fire Weather

  1. Southern and eastern Australia are projected to experience harsher fire weather, including an increase in the number of days with a ‘severe’ fire danger rating.
  2. Projections for fire weather in northern Australia and inland areas are less certain.

Sea level rise

  1. Sea levels will continue to rise throughout the 21st century and beyond.
  2. Projections of sea level rise for the Australian coastline by late in the century (2090) are comparable to, or slightly larger than, the projected global mean sea level rise of up to 82 cm under a high emission scenario.
  3. A collapse in the marine based sectors of the Antarctic ice sheet could make sea level rise projections several tenths of a metre higher by late in the century.

New South Wales distances itself from Abbott govt on Climate Change

climate-changeNSW signs up to global climate group, SMH, Peter Hannam February 1, 2015 The Baird government has moved to burnish its climate change credentials, becoming Australia’s first conservative government to sign up to The Climate Group.

NSW will join South Australia and Tasmania as the only Australian states to be members of the international non-profit organisation, which brings business, governments and communities together to promote renewable energy and cut carbon emissions blamed for global warming. Both SA and Tasmania signed up under Labor-led governments……….
NSW has distanced itself over the past year from conservative counterparts, including the Abbott government, on climate and other issues. It backed leaving the Renewable Energy Target as it is, in contrast to the Abbott government’s efforts to cut the 2020 goal by as much as 40 per cent, and has spent $3 million preparing climate change studies for expected impacts to 2030 and 2070……..
London-based The Climate Group shut its Australian offices in mid-2013, citing an “increasingly challenging political environment for action on climate change” at the time.

Its States & Regions members account for more than 300 million people and 13 per cent of global GDP, said Libby Ferguson, a group director.

NSW was “a forward-thinking state” with “progressive renewable policies”, Ms Ferguson said…..http://www.smh.com.au/environment/nsw-signs-up-to-global-climate-group-20150201-13301u.html

Climate change already impacting Australia’s sports

climate-changeGrassroots sports at risk from heatwaves due to climate change, report warns, Guardian, Oliver Milman  31 Jan 15 Extreme heat policies of sports such as tennis, Aussie rules and cricket will have to find ways to better protect the wellbeing of competitors as temperatures rise Climate change will threaten the viability of grassroots sport in Australia, and elite tournaments will have to adapt to rising temperatures, extreme rainfall and shrinking snow cover, a report has warned.

The extreme heat policies of sports such as tennis, Aussie rules and cricket will have to “dramatically improve” to protect the health of competitors at all levels, the Climate Institute analysis concluded.

The report, featuring a foreword from former AFL chief executive Andrew Demetriou, warned that while elite sport might be able to adapt to a changing climate, the “ability to respond at local sporting grounds is more questionable”.

The Climate Institute compiled the report in the wake of the blistering heat that affected the Australian Open tennis tournament last year. Players and court staff fainted, water bottles melted and a participant even warned someone might die after temperatures hit 43C.

The Open has since introduced new protocols that require the match referee to consider suspending play if the ambient temperature reaches 40C.

But the Climate Institute warned that the heat policies of other sports were patchy, with a recent AFL match taking place in 38C heat and last year’s Tour Down Under having no heat stipulations, even though cycling races in certain states are normally halted in extremely high temperatures.

“Heat policies are a bit confused and ambiguous between state and national levels,” said John Connor, chief executive of the Climate Institute. ……………

elongated droughts in parts of Australia, coupled with extreme rainfall, will degrade community sporting grounds and even affect large stadiums, such as the Suncorp stadium in Brisbane, which was covered in 1.5m of water during the 2011 Queensland floods.

Some of the most dramatic changes could hit those who enjoy winter sports, with the CSIRO report warning of “very substantial decreases in snowfall, increase in melt and thus reduced snow cover”…….http://www.theguardian.com/environment/2015/jan/30/grassroots-sports-at-risk-from-heatwaves-due-to-climate-change-report-warns

Scientists warn on climate change – a hotter drier South Australia

climate-AustSouth Australia to get much hotter, drier, new climate change report reveals The Advertiser  KATRINA STOKES JANUARY 27, 2015   SOUTH Australia is only going to get hotter and drier and more prevalent periods of drought and fire-related conditions will continue to increase, a report released today reveals.

The CSIRO and Bureau of Meteorology report says what climate change experts have been saying for a long time — climate change is real.

The experts predict Adelaide will experience an increase in the number of days above 35C from 20 in 1995 to 26 in 2030, to between 28 and 47 in 2090.

TO READ THE FULL REPORT CLICK HERE……..

ey predictions from the report include:

WINTER and spring rainfall in southern Australia is projected to decline, while changes in other areas are uncertain

THE time in drought will increase over southern Australia, with a greater frequency of severe droughts

BY 2090, Australian average temperatures are projected to increase by 0.6 to 1.7C for a low emissions scenario, or 2.8 to 5.1C under a high emission scenario

MORE hot days are like to occur as well as harsher fire weather, including an increase in the number of days with a “severe” fire danger rating

Climate Institute chief executive officer John Connor said the report findings demonstrated why it was in Australia’s best interest to “drive ambitious climate action”.

“This new data reinforces earlier analysis for Treasury (the government) that showed large chunks of the Australian economy will be whacked by global warming … sectors like agriculture, health and ecosystems are hit well beyond their ability to adapt,” he said……… http://www.adelaidenow.com.au/news/south-australia/south-australia-to-get-much-hotter-drier-new-climate-change-report-reveals/story-fni6uo1m-1227198291102?nk=12eb6391f5cbbe65f220fb12fca19ba4

Tony Abbott ‘frozen in time’ as Western Australia sizzles with climate change

heatWA sizzles as scientists reveal 2014 was the hottest in a century news.com.au JANUARY 18, 2015 NOT even the beach offered respite from the sun’s nuclear intensity as WA sizzled and the mercury approached 40C in Perth on Saturday…….Ambulance officers advised the elderly to stay inside and drink plenty of water and slip, slop, slap was the order of the day as the UV index peaked at 14. Readings of 11 and above are considered “extreme”.

But if you thought Perth was hot, spare a thought for Gascoyne Junction, near Shark Bay 1075km north of Perth, where the temperature was 47C, making it the hottest town in the state…….

New research from the US National Oceanic and Atmospheric Administration and the US space agency NASA shows 2014 was the hottest year in more than a century, reviving alarm about global warming.And WA’s top meteorologists agree, saying West Australians face decades of rising temperatures with hotter, drier and more extreme summers as a result of climate change.

Australia in 2014 experienced its third hottest year and hottest decade on record, according to the Bureau of Meteorology.

“It’s climate change. Temps across Australia are warming. There is no getting away from it,” weather bureau spokesman Neil Bennett said.

The NOAA report found that “globally averaged temperature over land and ocean surfaces for 2014 was the highest among all years since record-keeping began in 1880”. The average temperature in 2014 was 0.69C above the 20th century average, beating the previous record-holding years of 2005 and 2010. Russia, Alaska, parts of the US and South America, eastern and western coastal Australia, North Africa and most of Europe all experienced record heat.

Federal Labor environment spokesman Anthony Albanese said in the wake of the NOAA report that Prime Minister Tony Abbott can no longer ignore the evidence on climate change. “Tony Abbott is frozen in time while the world warms around us,” he said……http://www.news.com.au/national/western-australia/wa-sizzles-as-scientists-reveal-2014-was-the-hottest-in-a-century/story-fnii5thn-1227188545684?from=public_rss

The Global Catholic Climate Movement launched in Australia

climate-posterCatholics in Australia join global movement to curb climate change, The Age January 15, 2015  Environment Editor, The Sydney Morning Herald Australia’s Catholics are preparing to step up campaigns to address climate change ahead of an expected call to action by Pope Francis.

The Global Catholic Climate Movement, an international coalition of Catholic groups including Catholic Earthcare Australia, was launched on Thursday to bolster support for a global climate treaty at the Paris summit planned for December. That’s going to create real change that’s really needed, and that’s great.

Jacqui Remond, director of Catholic Earthcare Australia, said Catholics numbered one in four Australians and the time is ripe for them to push for greater action on curbing global warming.

“Looking at the leadership and the governance we have in Australia right now, there isn’t a lot of hope coming from the policies and the agenda that’s set,” Ms Remond said.

However, Ms Remond said hope is coming from abroad with Pope Francis expected to release the first encyclical on ecology as soon as March. The doctrinal directive is likely to focus on the damage to humanity and ecosystems caused by climate change.

“[The encyclical] has a significant influence because it sets a benchmark for learning for everyone in the church, which includes the cardinals, the bishops, the clergy, the lay people,” Ms Remond said. “This message will have an incredible ripple effect through the church and beyond.”

Ms Remond said Pope John Paul II and Pope Benedict XVI had also spoken out about climate change, with the latter installing solar panels on church buildings in Rome and making the Vatican the world’s first carbon-neutral state…….http://www.theage.com.au/environment/climate-change/catholics-in-australia-join-global-movement-to-curb-climate-change-20150115-12qs0r.html

The psychology behind climate change denialism, (helped by Murdoch media)

Climate change: Why some of us won’t believe it’s getting hotter, SMH January 11, 2015   Economics Editor, The Age What is it about the temperature that some of us find so hard to accept?

The year just ended was one of the hottest on record. In NSW it was the absolute hottest, in Victoria the second-hottest, and in Australia the third hottest………

when it comes to the slowly rising temperature some of us won’t even accept the readings. And that says something about us, or at least about those of us who won’t accept what’s in front of our faces.

I am not prepared to believe that these people are anti-science. Some of them are engineers, some mining company company executives. Like all of us, they depend on science in their everyday lives.

News-Limited1Nor am I prepared to believe they’ve led sheltered lives, although it’s a popular theory. In the United States a survey of six months of coverage on Rupert Murdoch’s Fox News Channel found that 37 of its 40 mentions of climate change were misleading.

The misleading coverage included “broad dismissals of human-caused climate change, disparaging comments about individual scientists, rejections of climate science as a body of knowledge, and cherry-picking of data”.

Fox News called global warming a “fraud”, a “hoax” and “pseudo science”.

Rupert Murdoch’s Wall Street Journal fared little better. 39 of its 48 references were misleading.

In Australia it’s not as bad. Rupert Murdoch’s The Australian gives more space to climate change than any other newspaper. Its articles are 47 per cent negative, 44 per cent neutral and 9 per cent positive, according to the Australian Centre for Independent Journalism.

It’s impossible to read The Australian‘s articles without feeling at least a bit curious about climate change.

Another theory is that it’s to do with psychology. Some people are more threatened by bad news than others, making them less able to accept that it’s real.

And now a more sophisticated theory suggests that it’s not about the facts at all. It’s really a debate about the implications, disguised as a debate about the facts. Troy Campbell and Aaron Kay, a researcher and associate professor in neuroscience at Duke University in North Carolina find that belief in temperature forecasts is correlated with beliefs about government regulation and what those forecasts would mean for government regulation……..http://www.smh.com.au/comment/climate-change-why-some-of-us-wont-believe-its-getting-hotter-20150110-12koa1.html

Three Australian States pushing Fed govt for climate change action

Climate change push as Victoria seeks to join with NSW and South Australia‘ Each state has a responsibility to push the federal government in this area,’ Victorian environment minister Lisa Neville says. Guardian 8 Jan 15, The Victorian government wants to join forces with New South Wales and South Australia to press the federal government for more action on climate change in the wake of record or near-record temperatures in the three states in 2014.

Victoria’s environment minister, Lisa Neville, said she was seeking “urgent” talks with the NSW and SA governments to forge a united front against Tony Abbott’s stance on climate change.

Neville told Guardian Australia the states would seek greater clarity on how the federal Emissions Reduction Fund, which will provide grants to businesses, would work. The federal government’s leadership on climate change would also be questioned.

“I’m looking to have urgent conversations with NSW and South Australia on the role they can play with us,” she said. “We’ll look at whether there’s a shared view on emissions reduction and also national advocacy so we can put climate change back into public debate.

“Each state has a responsibility to push the federal government in this area. National action will have the most impact on climate change, so we need a unified voice to get the federal government, first of all, to acknowledge climate change.

“The Abbott government has, unfortunately, walked away from its responsibility to act on climate change. We’d prefer strong national and international action, but if we have to play a leadership role in Victoria, we will do that.

“We need to put pressure on the federal government as well as build a proper community conversation about climate change again.”

Neville, who will have her first meeting with the federal environment minister, Greg Hunt, this month, said the federal Coalition needed to resolve the “mess” surrounding its attempts to cut the national renewable energy target and ensure its ERF grants were spent effectively to bring down emissions……….

South Australia’s renewable energy investment has forged ahead of Victoria and NSW, at a time when all states are experiencing a trend of rising temperatures…….

The NSW government, while keen to not publicly criticise its Coalition counterpart in Canberra, has indicated that it wants stronger action on climate change…….“The NSW government also has a renewable energy action plan to increase the proportion of renewable energy in NSW and has made its position on the renewable energy target clear.”

Global warming contributed to Sydney’s record warm year

heatSydney weather: Record warm year with few cold spells January 6, 2015  Environment Editor, The Sydney Morning Herald

If you thought Sydney had been warm over the past year or so, you’d be right.

Last year was the city’s equal warmest for overnight temperatures and its second-warmest for means and maximums in 156 years of record keeping at Observatory Hill.

For some temperature measures, such as for NSW heat, the previous record had been set only a year earlier.

Agata Imielska, senior climatologist at the Bureau of Meteorology in Sydney, said it was “quite surprising” to see last year eclipse 2013 given the bar had been set so high.

“We just didn’t have the cool periods,” Ms Imielska said. “There was a real persistence in the warmth.”

……….Nationally, mean temperatures in 2014 came in 0.91 degrees above the 1961-1990 average, behind only 2013 and 2005, the bureau said in its annual report. Rainfall was slightly above average, with the north unusually wet and the south largely drier than normal.

Globally, 2014 was the hottest year on record, the Japan Meteorological Agency declared this week. Land and sea-surface temperatures were 0.27 degrees above the 1981-2010 average, easily eclipsing the previous highs set in 1998, 2010 and 2013.

“Global warming is contributing to these heat records, and it’s very unlikely that we would have seen the proliferation or the frequency of these heat records around the world without the influence of global warming,” Karl Braganza, head of climate monitoring at the bureau, said.

“The climate system we live in … that’s all about 1 degree warmer than it used to be,” Dr Braganza said.

Warm and dry

For NSW, 2014 was the hottest on record for mean temperatures and the equal warmest for maximums. Among the other states, only the Northern Territory failed to notch a year among the four warmest on record……….http://www.smh.com.au/environment/climate-change/sydney-weather-record-warm-year-with-few-cold-spells-20150106-12ikgr.html

Hottest daytime temperatures on record – Victoria in 2014

heatVictoria experienced hottest daytime temperatures on record in 2014, BOM annual report reveals, ABC News By Loretta Florance 5 Jan 15 Victoria recorded its hottest year on record for maximum daytime temperatures in 2014, the Bureau of Meteorology’s (BOM) annual report has revealed.

The state also recorded the second warmest year on record for mean temperatures, and the third warmest for minimum temperatures. The mean maximum temperature was 1.53 degrees Celsius above average, the Bureau of Meteorology found………

climate modelling showed that an El Nino effect on both the atmosphere and the ocean might progress over the summer, which would mean warmer temperatures in Victoria.

“We know that the year an El Nino event gets going tends to be the warmer years, so globally you’d expect 2015 to be at least as warm as 2014 if not warmer – and 2014 globally is actually looking like it’s going to be the warmest year on record,” he said.

“For eastern Australia, you tend to have the warm conditions persist through the financial year, so at least until the middle of next year, is what you’d be expecting for average conditions.” http://www.abc.net.au/news/2015-01-06/victoria-swelters-through-its-hottest-year-on-record-2014/6002710

Health of Australians already threatened by global warming

heatAs shepherds watched, it got hotter and hotter December 24, 2014  Environment Editor, The Sydney Morning Herald Human health – and that of other animals and even plants – is likely to become an ever more pressing public issue as temperatures rise with global warming, cities grow and populations age………

Until recently, public health authorities would issue a warning whenever the temperature was likely to exceed a certain level.

However, heatwaves are also related to the conditions people are accustomed to. To reflect that, the Bureau of Meteorology last year pioneered a heatwave service that predicts the severity of coming heatwaves based on both how far temperatures are likely to deviate from historical averages but also taking into account the previous month’s weather.

In a further tweak, the bureau has added charts to assess the impact of each heatwave after it’s hit. That’s needed because people often don’t realise the damage to health can come from exposure to prolonged warmth rather than a particular temperature spike. Continue reading

Australia’s carbon tax resulted in dramatic decline in greenhouse gas emissions

New data shows record fall in carbon emissions , The Age  Gareth Hutchens December 23, 2014 -  Environment Minister Greg Hunt has quietly published data, just two days before Christmas, showing the second year of operation of Australia’s carbon price was more successful at reducing emissions than the first.

New data from Australia’s National Greenhouse Gas Inventory show emissions declined across Australia by 1.4 per cent over the 12 months to June.

That compares to a decline in emissions of 0.8 per cent for the previous 12 months.

The carbon price was introduced by the Gillard government and began operation on July 1, 2012. It ended on July 1, this year after the Abbott government fulfilled an election pledge by abolishing it.

The new data, published on Tuesday, record emissions produced during the final year of operation of the carbon price, from June 2013 to June 2014.

They show the electricity (minus 4 per cent), agriculture (minus 2.6 per cent), industrial processes (minus 1.3 per cent) and transport sectors (minus 0.4 per cent) all experienced declines in emissions this year………….

Greens Leader Christine Milne has slammed the federal government for waiting until after the Lima Climate Change Conference to release the data, saying the figures show just how effective Australia’s carbon price was at bringing down pollution.

“This is the biggest ever drop recorded and the price made it happen,” Ms Milne told Fairfax Media.

“Why did the government withhold this report until after the Lima climate talks? These are embarrassing figures for the Abbott government because they demonstrate just how destructive they have been to the global effort to reduce pollution and tackle dangerous global warming,” she said…….http://www.theage.com.au/environment/climate-change/new-data-shows-record-fall-in-carbon-emissions-20141223-12d1z3.html
