When It Rains It Pours, And Sewage Hits The Fan

Climate Central - Alyson Kenward | Nicole Zenes | James Bronzan | Jennifer Brady | Kasturi Shah

Record rainstorms across the U.S. in the past year have continued to make national news, causing billions of dollars of flood damage and killing dozens. But what has barely made headlines are that these floods often cause massive overflows of untreated sewage into streams, rivers, bays, canals, and even streets and homes. See the full report.
Climate Central has investigated the extent of these sewage overflows. In most cases, we found reports that millions of gallons of untreated sewage were released into streets and waterways. These overflows can have devastating consequences for public health and the environment: they can trigger dangerous outbreaks of waterborne diseases and are often linked to fish kills. And when sewage overflows into homes and businesses, expensive remediation and decontamination is needed to make them safe again.
Worse was the discovery that the true extent of sewage overflow is often undocumented and largely unknown.
From the 70 sewage overflows we identified that had occurred in the past 20 months, overflows of more than one billion gallons combined were reported, triggering health warnings in dozens of cities. Local officials confirmed that these reported volumes are likely underestimating the true extent of overflows; during these flooding emergencies, there is typically no reliable way to determine how much untreated sewage gets into the waterways.
With a backdrop of antiquated and overpopulated sewer systems, the increase in rain and heavy downpours in recent decades — one of the ongoing impacts of climate change — continues to trigger overflows that affect millions of Americans every year.
While many cities are working toward upgrading their sewer systems, they can’t eliminate their sewage overflow risks entirely. Climate models project that both overall precipitation, and the amount of rain falling in heavy downpours, will continue to increase this century with continued climate change, which could cause even more overflows.
According to the National Oceanic and Atmospheric Administration (NOAA), the epic rains in Louisiana in August 2016 that flooded 60,000 homes and killed 13, were made nearly twice as likely due to carbon pollution in the atmosphere. Climate Central’s analysis of more than 3,000 rain gauges nationwide shows that heavy downpours are happening more frequently than they did in the 1950s. We found that all but two of the Lower 48 states have seen an increase in the number of heavy downpours happening each year, on average, compared to the 1950s, and 28 states have seen at least a 25 percent increase in these heaviest events. With downpours projected to be even more frequent and intense as the world continues to warm, we can expect more of these costly and dangerous overflows for many years to come.

Australian Scientists Found The Gene Trees Use To Adapt To Climate Change

Gizmodo


Major new international research involving Monash University has found that despite 140 million years of independent evolution, two distinct types of coniferous trees use the same small set of 47 genes (of 23000) to rapidly adapt to varying climates.
Monash University Scientist Dr Kay Hodgins said the finding was astonishing with implications for sustainability, industry and research.
“Despite the fact these trees have evolved as separate species for roughly as long as humans and kangaroos, these two distantly-related types of trees use variation in the same genes to deal with the different climates they both inhabit,” Dr Hodgins said. “Understanding how trees adapt to climate will help us make better decisions about where trees should be planted.”
Dr Hodgins said trees are becoming mismatched to their local climates, which is becoming an issue.
This research has major significance for trees, the ongoing human consumption of wood and pulp products such as paper and fibre as well as how nations address climate change.
Senior author, Forestry Professor Sally Aitken, from the University of British Columbia said that faced with drought or cold, trees decide to turn thousands of genes on or off to deal with changes in temperature and moisture. This suggests there may be multiple ways trees in a region can adapt to local climate.
“But after sequencing the DNA of 23,000 specific genes from hundreds of pine and spruce trees in B.C. and Alberta, our research found that the two tree species used DNA variation in the same 47 genes to adapt to low or high temperatures,” said Professor Aitken.

Galilee Basin Coal Must Be Left In Ground As A ‘Priority’ – New Report

The Guardian

Oil Change International argues there is a compelling case for six proposed Queensland projects to be axed in 'managed decline' of fossil fuel

Miners seeking the green light to dig up Queensland's Galilee basin should be stopped as a priority, according to a new report showing existing fossil fuels projects worldwide are enough to push global warming beyond 2C.
The report by the research and advocacy group Oil Change International argues there is a compelling case for the six Galilee coalmining proposals in the hands of Australian regulators to be axed in line with a "managed decline" of global coal, oil and gas supplies already on tap.
It shows the embedded carbon emissions from operating fields and mines worldwide, if run to the end of their projected lifetimes, would drive warming beyond the 2C limit laid down by last year's Paris agreement. Developed oil and gas reserves alone would take warming beyond the aspirational 1.5C target.
The report shows that if Australia fully exploited its untapped coal reserves – the third largest in the world behind the US and Russia – the resulting emissions would blow almost a third of the world's carbon budget for 1.5C.
About a fifth of these emissions (24 gigatonnes) would come from the six Galilee mining hopefuls who have applied for permits.
The largest is Adani's Carmichael mine, which over its lifetime would contribute more than half of these emissions through 5 bn tonnes of coal.
The China First mine proposal by Clive Palmer's Waratah Coal, which like others in the Galilee appears to hinge on Adani paving the way with rail infrastructure, is the third largest at 1bn tonnes.
The report singles out Australia and the Galilee as being on the "frontline of expansion" of the global coal industry and stopping this development "must be a priority".
"The consequence of our analysis is that no new extractive or facilitating infrastructure should be built anywhere in the world," it says.
Fellow coal giants China and Indonesia have enacted temporary bans on new coalmines and the US has a limited moratorium on new mines on public land.
That leaves Australia as one of just "two countries that are currently proceeding with major coalmining development", along with India, the report says.
India, with its urgent need for economic uplift and relatively low contribution to historical emissions, could be given a "generous support package" funded by wealthy countries to pursue low-carbon development.
But the "hard choices" by governments about phasing out existing projects should start in the developed countries such as Australia, the report says.
Adani, an Indian conglomerate, has argued its Australian mine would be pivotal in helping the Indian electricity sector move towards making cheap energy available to the impoverished. The "energy poverty" argument is contested by Adani's critics.
The company, which has been embroiled in a long series of legal challenges in Queensland from traditional owners and conservationists, has reportedly downsized the first phase of its mine and put off an investment decision till the end of 2017.
The mine would now cost $4bn to get off the ground and initially produce 25m tonnes a year, with 80% slated for its sister energy company Adani Power, the Australian Financial Review reported.
Tim Buckley at the Institute for Energy Economics and Financial Analysis said Adani's scaled-down plans remained "unbankable" for a company that held US$2.6bn net debt beside a market capitalisation of just US$1.2bn.
Adani Power was in even worse "financial distress", with net debts of more than US$7.3bn against market capitalisation of US$1.4bn, Buckley said. It was also yet to build most of the large power stations in western India which Carmichael would supply.
"Lacking economies of scale, this low-quality thermal export coal proposal lacks strategic relevance in India where the installed cost of solar is now lower than that of imported thermal coal," he said.
This casts doubt on broader development prospects in the Galilee basin, which Buckley said was "still stranded 400km inland from the coast without any industrial-grade power, road, water, aviation or rail infrastructure in place".
The report's author, Greg Muttit, said there were "only three possibilities" to consider in the future of fossil fuels extraction.
"We can manage the decline of our existing fields, shifting to clean energy and redeploying workers," he said. "Or we continue to develop new reserves that then have to be shut down suddenly, stranding assets, costing investors, and causing havoc in fossil fuel extraction-dependent communities.
"Or we just carry on as we are – and wreak economic, ecological and human catastrophe on the world."
Stephen Kretzmann, the executive director of Oil Change International, said: "If the world is serious about achieving the goals agreed in Paris, governments have to stop the expansion of the fossil fuel industry.
"The industry has enough carbon in the pipeline – today – to break through the sky's limit."
The report says the study was the first to examine the climate change implications of potential emissions from current oil, gas and coal operations in light of the Paris agreement. It draws on industry data from the oil and gas consultancy Rystad Energy and carbon budgets derived from the Intergovernmental Panel on Climate Change.

Does Treasury Believe In Climate Change?

Crikey - Bernard Keane

Is climate change real? The Treasury and Prime Minister and Cabinet appear to disagree, if their corporate plans are anything to go by.
Treasury Secretary John Fraser
Some bright young faces gleam out from the latest Corporate Plan from Treasury, which according to secretary John Fraser — whose not-so-bright face also appears — "sets out the Department's purposes, priorities and the key directions".
What are those priorities? Productivity? Check. Participation? Absolutely. Ageing population? Yep. The budget? Of course — there's a section on "promoting fiscal sustainability". Infrastructure? Well, there are a few mentions. Globalisation and global integration get a section, suggesting the best and the brightest are aware of the increasingly sensitive issue of the political downsides of globalisation.
But climate change? Not so much. There's not a single mention of the greatest long-term economic challenge to Australia in the document.
As we've noted before, John Fraser — who dates from the old John Stone Treasury era — seems to have had his mind frozen in the early 1990s. At least he's now mentioning infrastructure, which has been absent from his major speeches, but climate change, a glaring absence in those addresses, remains verboten.
There's virtually no mention of climate change at all on the Treasury site anymore, except in the submissions provided by stakeholder groups to Treasury in various consultation processes. Search for climate change-related documents via Treasury's own internal search engine and all it produces are two "historical" documents from the Labor years.
In contrast, Martin Parkinson now has a "Climate Change and Environment" branch back in Prime Minister and Cabinet — rather a contrast to the Abbott years when "climate change" had to be purged from that department and Parkinson himself was sent packing from Treasury by Abbott for his sin of being secretary of the Department of Climate Change under Labor. And PM&C's Corporate Plan talks about "providing advice on major policy areas, including health, education, social security, infrastructure, industry, energy, climate and the environment, and regulatory reform" — rather a contrast to last year's document, written while Abbott was still prime minister and Michael Thawley headed PM&C, where climate change doesn't get a mention.
Maybe Fraser's holding out hope for that Abbott resurrection, which will mean we can go back to the days when we stuck our fingers in our ears and pretended climate change wasn't real.
