Australia's west, south losing vital rain as climate change shifts winds, study finds

Rising greenhouse gases and ozone depletion over the Antarctic are increasingly pushing rain-bearing storm fronts away from Australia's west and south, according to a new international study.

The research, which involved the Australian National University and 16 other institutions from around the world, has just been published in the Nature Climate Change journal.

It found Southern Ocean westerly winds and associated storms were shifting south, down towards Antarctica, and robbing southern parts of Australia of rain.

ANU Associate Professor Nerilie Abram, the lead Australian researcher, said this had contributed to a decline of more than 20 per cent in winter rainfall in southwestern Australia since the 1970s.

scientific american.com reports the following:

Earth’s CO2 Passes the 400 PPM Threshold—Maybe Permanently?

Carbon dioxide levels often hit lows,
in September, but now remain above a crucial benchmark.

In the centuries to come, history books will likely look back on,
September 2016 as a major milestone for the world’s climate.
At a time when atmospheric carbon dioxide is usually at,
its minimum, the monthly value failed to drop below 400 parts per million.

That all but ensures that 2016 will be the year that carbon dioxide,
officially passed the symbolic 400 ppm mark,
never to return below it in our lifetimes, according to scientists.

Because carbon pollution has been increasing since,
the start of the Industrial Revolution and has shown no signs,
of abating, it was more a question of,
“when” rather than “if” we would cross this threshold.
The inevitability doesn’t make it any less significant, though.

September is usually the month when carbon dioxide,
is at its lowest after a summer of plants growing and sucking,
it up in the northern hemisphere.

As fall wears on, those plants lose their leaves,
which in turn decompose, releasing the stored carbon dioxide,
back into the atmosphere. At Mauna Loa Observatory,
the world’s marquee site for monitoring carbon dioxide,
there are signs that the process has begun
but levels have remained above 400 ppm.

Slightly off topic perhaps, or a new direction for looking at climate.

Time to adapt: 2015's record-breaking temperatures will be normal by 2030

2016 is on track to be the hottest year on record, surpassing the previous records set in 2015 and in 2014. These are just a few of the flurry of recent record temperatures, which includes Australia's hottest day, week, month, season and year.

The question now is what the future will look like. At some point in the decades to come, these record-breaking temperatures will not be rare; they will become normal. But when exactly?

WMO: Five hottest years on record have occurred since 2011.

http://www.bbc.co.uk/news/science-environment-37900400

New data released by the World Meteorological Organisation (WMO) shows that the five years from 2011 to 2015 were the warmest on record.

The report, published at global climate talks in Morocco, strongly links human activities to rising temperatures.

It says that some studies found the the burning of fossil fuels had increased the probability of extreme heat by 10 times or more.

The authors say that 2016 will likely break the record for warmest year.

Some people may not consider this climate news, but I do. In case you missed it, Donald Tramp will be the next President of the United States. This is very bad news for climate stabilization. Donald Tramp is, quite simply, a climate change denier. He has gone on record say that he believes that climate change is a “hoax, invented by the Chinese to cripple American industry.” He has also stated that when President he will "roll back" the Paris Accords. If he does this it is likely that most of the other industrial countries will do the same.

The Republican Party has also retained a majority in both Houses of Congress. The Republican Party is the very home of climate change denial in American politics. For at least the next 2 years it will be open season on America’s environmental laws, including those having to do will greenhouse gas emissions.
Until these people are out of power it is unlikely that the United States will do anything to limit global climate change or honor any existing commitments made by past Administrations.

Unfortunately I don't think that the timescale for global sea level rise wiill be fast enough to flood his Florida properties. However there is the alternative hypothesis that lack of Arctic ice will "turn off" the Gulf stream causing massive freezing along the American east coast. I doubt if most of us will be around to see it though. As always it's left to those who follow to clean up the mess.
The near future is not bright - it's almost orange!

http://www.abc.net.au/news/2016-11-14/csiro-investigate-ocean-currents-explain-high-ocean-temps/8022946

A team of Australian researchers has taken to the sea to help track ocean currents in an effort to understand their impact on the climate.

The findings of the long-term project will form part of a global program aimed at monitoring changes in the world's oceans.

...

On the latest research voyage she oversaw the retrieval and redeployed of six large moorings equipped with state-of-the-art sensors.

Anchored at depths ranging from 500 metres to 4 kilometres, they are spread across the east Australian current.

Every second, the massive movement of water shifts the equivalent of 10,000 Olympic swimming pools south, from the tropics to the southern seas.

"And as it goes south, it slowly releases all the heat that's stored ... that impacts our climate and our weather on the coast but also impacts all of the marine ecosystems along the coastal regions of Australia," Dr Sloyan said.

His trade protectionism could throw the U.S. and the world into a Great Depression. That would do wonders to reduce CO2 production. And after the rebound, solar power may be more feasible.

W. was rather green too. The Republicans just never claim credit for it.

This is one of the most important projects that we could all be working on, definitely!

I am proud to have at least one of my computers number crunch for ClimatePrediction.net!

Central Melbourne gets a tree change in readiness for hotter climate


Many of Melbourne's established elm and plane trees are struggling to cope with rising temperatures and drier conditions.

So Melbourne City Council is gradually switching to species that will cope better with a hotter climate.

The council and Melbourne University today released a report advising which trees to plant to better prepare for climate change.
Dr Dave Kendal studied tree inventories from 200 countries and selected 875 species suitable for warmer temperatures and sub-tropical climates.

NASA director debunks Malcolm Roberts' theory on climate data manipulation in polite letter

In a politely worded letter, the director of NASA's Goddard Institute for Space Studies (GISS) has addressed One Nation senator Malcolm Roberts' concerns that the organisation's data on climate change has been manipulated.

In a rare occurrence, director Gavin Schmidt personally wrote a letter in response to Senator Roberts' request for information about the NASA GISTEMP analysis of global surface temperature history.

The GISS Surface Temperature Analysis (GISTEMP) is an estimate of global surface temperature change.

The latest from One Nation:

Pauline Hanson visits healthy reef to dispute effects of climate change
One Nation leader Pauline Hanson has been ridiculed for visiting a healthy section of the Great Barrier Reef while denying the effects of climate change.

Senator Hanson and other One Nation senators donned wetsuits, snorkels and masks for a tour of the reef in a show of support for Queensland's tourism industry.

Senator Hanson disputed claims from the world's leading scientists that the reef experienced its worst ever bleaching event in 2016.

She said the publicity surrounding bleaching events was hurting the tourism industry.

...

But the section of reef they visited was off the coast of Rockhampton in central Queensland, about 1,000 kilometres south from where a serious bleaching event occurred near Lizard Island.

How climate change is affecting the wine we drink

Family-owned winemaker Brown Brothers has been growing grapes in Victoria since the 1880s.

The company was founded by John Francis Brown, but established its reputation and success under his son John Charles Brown.

When John returned to Milawa in regional Victoria after finishing boarding school in 1958, he harvested his first vintage of grapes in the early days of April.

Fifty years later, the grapes are off the vines by April, with picking often starting in February. Within a generation, the harvest start date has shifted along with the climate in the valley.

It's a dramatic indication of how climate change is affecting the way we make wine in Australia.
