Dead Fish Could Stink Up The Election Campaign

The Australian climate has interceded in national politics more than once.
Malcolm Fraser went to the electorate in 1983 at the height of one of the harshest droughts on record.

The previous year's wheat crop had been the worst in decades for much of the east coast, while many graziers were forced to destroy livestock left without feed or water.
Just weeks ahead of the 1983 election, the Ash Wednesday bushfires killed 75 people in Victoria and South Australia, destroyed more than 3700 buildings and resulted in the death of an estimated 340,000 sheep.
The government could not be blamed but there were some within the Liberal Party that argued Malcolm Fraser  had been blamed for everything – including the drought.
That was, perhaps, brought home when within a fortnight of Bob Hawke's victory, record-breaking rains fell across the parched landscape.
In 1991 the NSW government declared a state of emergency after a 1000km blue-green algal bloom erupted down the Darling River.
The pictures of the bloom, and the public demand for action they elicited, forced governments across the Murray-Darling basin to take the first steps towards better management of our water systems.
The 2007 election was not marred by environmental disaster but climate – and the Howard government's response to climate change – became a hammer blow used by Kevin Rudd.
Less than three years later it was Rudd being hammered. The man who declared climate change the great moral, social and economic challenge was gone after he failed rise to the challenge he had identified.
Tony Abbott and Malcolm Turnbull continued the climate change wars, both succumbing to wounds inflicted by themselves and others. And when Scott Morrison replaced Turnbull, the new PM's first visit was to drought-afflicted Queensland before assembling a "drought summit".
Now 14 weeks out from the expected May federal election, the environment has interceded in the political debate again.
The pictures, video and social media posts of the fish kill around Menindee on the Darling River have been visceral.
Images of old and angry fishermen and farmers, holding up the rotting carcasses of Murray cod have been beamed into the nation's lounge rooms or on to our smart phones.
In the face of criticism from those fishermen, farmers and locals, the Morrison government has effectively said "let's hope for rain" and "it's the drought".
The problem with that argument is that it may very well be exposed by a South Australian royal commission into the Murray-Darling and its management.
In less than a fortnight, the royal commission started by then SA Premier Jay Weatherill is due to report.
The evidence to it, particularly about the Murray-Darling Basin Authority, has been compelling.
And the findings may be as politically toxic as those rotting fish in the Darling.
In his final address, senior counsel assisting the commission Richard Beasley did not hold back in his criticisms of the MDBA and its political masters who are scattered across the federal, NSW, Queensland, SA and Victorian spheres.
Describing issues of "maladministration" and "unlawfulness", Beasley sheeted home blame to those in charge.
"The implementation of the [Murray-Darling] basin plan has been marred by maladministration. By that I mean mismanagement by those in charge of the task in the basin authority, its executives and its board, and the consequent mismanagement of huge amounts of public funds," he said.
"The responsibility for that maladministration and mismanagement falls on both past and current executives of the MDBA and its board."
The commission heard evidence of how problems setting the amount of water put aside for the environment started under the Rudd government and have continued ever since. That includes the past six years of oversight by the Abbott-Turnbull-Morrison government.
The coalition, particularly the National Party, was always more interested in modernising the irrigation systems across the Murray-Darling rather than buying allocations direct from willing sellers.
A draft report from the Productivity Commission found the government's preferred process has been extremely expensive – upgrading irrigation pipes and drains is twice the cost of buying water on the open market.
While the PC found the upgrade irrigation system process has "lessened" the socio-economic costs of directing water to the environment, it too was just as damning as Beasley to the royal commission.
It noted that the evidence so far was that while the process had provided "a number of private benefits for irrigators" this had failed to sustain regional farming communities.
Like those rotting fish, the PC's final report is just waiting to go off. Delivered to the government last month, the report has to be made public soon – almost about the same time as the royal commission reports to the SA government.
Scott Morrison needs almost everything to go right for him to win this year's election.
There are those things he can control directly, such as government policy; there are those things he has to target, such as Bill Shorten and Labor's overall policy agenda; and then there are those issues that come from left field.
Scientists have been warning for decades about the problems facing our most important inland water system, so it's difficult to claim the events playing out on the Darling are truly a surprise.
But the footage of men holding aloft dead Murray cod while surrounded by rotting carp, yellowbelly and bony bream was not expected. Nor the record temperatures of recent days which has turned parts of NSW, Victoria and South Australia into fan-forced ovens.
It may be just another sign of how the natural environment, if ignored for too long, finds a way to seep into the national political discourse.

Our Oceans Broke Heat Records In 2018 And The Consequences Are Catastrophic

The Guardian

Rising temperatures can be charted back to the late 1950s, and the last five years were the five hottest on record

Last year was the hottest ever measured, continuing an upward trend that is a direct result of manmade greenhouse gas emissions.
The key to the measurements is the oceans. Oceans absorb more than 90% of the heat that results from greenhouse gases, so if you want to measure global warming you really have to measure ocean warming.
There are other ways to measure climate change, but none are as convincing as the oceans. Air temperatures are most commonly reported in the media as evidence of global warming, but the problem with these is they are very erratic. While there is certainly a long-term trend of higher air temperatures, any given year may be warmer or colder than the last.
So oceans are key, and they are telling us a clear story. The last five years were the five hottest on record. The numbers are huge: in 2018 the extra ocean heat compared to a 1981-2010 baseline amounted to 196,700,000,000,000,000,000,000 joules. The current rate of ocean warming is equivalent to five Hiroshima-size atomic bombs exploding every second.
The measurements have been published in the journal Advances in Atmospheric Sciences in an article by Lijing Cheng, the lead author, and his colleagues from the Institute for Atmospheric Physics in China. His collaborators, of which I am one, included researchers from around the world. The article charts ocean heat back to the late 1950s, showing a steady increase.

Ocean warming is incontrovertible proof of global warming, and there are real consequences to a warming ocean. Firstly, warmer water expands, and this expansion causes sea levels to rise. Approximately a third of the rise in ocean waters is a result of the heat absorbed by the oceans. Scientists expect about one metre of sea level rise by the end of the century, which would be enough to displace 150 million people worldwide.
The warming waters also make storms more powerful. In the US recently, we have seen hurricanes pass over extremely warm ocean waters, which has supercharged them and increased the damage they cause. Other kinds of storms are also being made stronger. Heavier downpours of rainfall are increasing flooding around the world. Simply put, our emissions of greenhouse gases have caused loss of life and property. We are all responsible, but the people who have denied the science and the solutions own a special responsibility that history will judge harshly.
It isn’t just humans that are suffering and will suffer more in the future. The heating of oceans is causing tremendous problems for sea life, particularly coral reefs. If we continue to warm the planet, we can expect to lose much of these reefs. We can also anticipate reductions in fish and sea life populations.
We scientists sound like a broken record. Every year we present the science and plead for action. Not nearly enough is being done. We can still tackle climate change, but we must act immediately. We have the means to make a difference, we lack only the will.
