1. Will Australia be to world climate talks what Poland is to Europe?

That’s the question asked by Giles Parkinson.

On the international stage Australia plays a similar role to Poland in Europe. The two countries have much in common: their leaders share a tenuous hold on climate science, a grim determination to extract coal and use it for electricity, don’t like carbon pricing and are trying to keep a lid on renewables.

From what he says, there does seem a difference. Poland gained free carbon permits from the EU negotiations “worth more than $1 billion and promises for funds to help it “modernize” is coal-fired plants after 2020.”

Prime Minister Ewa Kopacz said after the summit that the threat of veto was simply a “tool” to get the best conditions for Poland’s economy. “Nobody got compensated like we did,” she boasted after the meeting.

In other words they were out for what they could get.

On the basis of the Abbott Government’s form in the UNFCCC Conference of Parties in Warsaw last December and actions since, we can expect Australia to be actively hostile to positive outcomes. Not just lead in the saddle bag, an active saboteur.

2. The prospect of a Republican US Senate

There is a 68% chance that the Republicans will control the US Senate after the mid-term elections. For the climate this could be a disaster.

Certainly they are unlikely to control the 60 votes they would need to avoid a Democrat filibuster, and the President has the power of veto over bills. So anti-climate legislation is not so much the worry.

However, the Republicans could block appropriate appointments to various agency positions and regulatory posts.

Secondly, any treaty coming out of the 2015 UNFCCC talks in Paris next year would need to be legislated. This would be impossible and could affect the tenor of the entire negotiations, with one large lame duck at the table.

Third, the US contributions to the IPCC and the UNFCCC could be pulled, making life for those bodies impossible.

Fourth,

a GOP majority in that house of Congress would flip several key committees into Republican hands. In particular, Sen. Jim Inhofe (R-OK) is up to take over the Environment and Public Works Committee, Sen. Ted Cruz (R-TX) would head the Subcommittee on Science and Space, Sen. Ron Johnson (R-WI) is in line to take control of the Homeland Security and Governmental Reform Committee, and Sen. Mike Enzi (R-WY) would head up the Budget Committee.

All except Enzi are avowed climate denialists.

Then there’s scary budget negotiations, and more.

3. Global groundwater crisis

AP190188023717-256x171

A NASA study has found that major groundwater aquifers are being depleted faster than the rate of replenishment, threatening food supplies and security.

The groundwater at some of the world’s largest aquifers — in the U.S. High Plains, California’s Central Valley, China, India, and elsewhere — is being pumped out “at far greater rates than it can be naturally replenished.”

The most worrisome fact: “nearly all of these underlie the word’s great agricultural regions and are primarily responsible for their high productivity.”

4. Geoff Cousins heads the ACF

You’ll probably recognise the gravel-voiced tones of Geoff Cousins from his campaign against the Gunns paper mill. He used 20,000 signatures from ANZ customers to pressure the bank to withdraw the project’s funds.

From the SMH:

His business credentials include heading the country’s largest advertising company and heading Optus Vision when it slugged it out with News Ltd over rugby league broadcasting rights. He is a director of the Telstra board.

He is now President of the Australian Conservation Foundation, so expect to hear more from him. Now he’s lashed out at the Direct Action legislation and given the BCA (Business Council of Australia) a whack around the ears for supporting the legislation which he says individual companies would have rejected.

If somebody had brought a business case to the boards of one of those public companies for this program, no responsible board would have given it the time of day.

You would have asked first of all how cost efficient it was, you would have asked what was world’s best practice in all of these areas, these sorts of questions, and none of them would have been able to be answered positively in regard to this program.

The ACF are now embarking on a public education campaign about the legislation.

5. Food, Fossil Fuels and Filthy Finance

That’s the title of a report from Oxfam, summarised at Hot Topic.

On current trends, the world will be 4–6ºC hotter by the end of the century, exceeding 2ºC within the lifetimes of most people reading this report. This could put up to 400 million people in some of the poorest countries at risk of severe food and water shortages by the middle of the century.

This paper shows how, despite some steps in the right direction to tackle climate change, a ‘toxic triangle’ of political inertia, financial short-termism and vested fossil fuel interests is blocking the transition that is needed. To help break this, governments must commit to phase out fossil fuel emissions by early in the second half of this century, with rich countries leading the way.

In 2012 fossil fuel companies spent $674bn on exploration and development projects. The industry is supported by $1.9 trillion of subsidies public finance, incentives and tax breaks, including the costs of paying for its widespread damage.

Quite simply, most of the stuff should be left in the ground:

In truth, that’s generous!

Climate clippings 98

This edition includes important updates on Greenland and Antarctica, global food supply, CSIRO cuts, CO2 levels moving decisively past 400 ppm and CO2 compared to global temperature rise.

1. Greenland may melt faster than expected

You may recall from the post Arctic images I included an image of the underlying topography of Greenland (Figure 5). It is saucer-like with large areas inland below sea level. The glaciers tend to drain through narrow gateways in the external rim. So they tend to be narrow and fast-flowing:

Glacier_assets-climatecentral-org-images-uploads-news-5_16_14_Andrea_Greenlandglacier-500x331

The mouths of most glaciers are melting from contact with warmer seas. It was felt that as this process continued the ice would lose contact with the water, slowing the melting.

New studies of the topography have shown that many of these channels are below sea level.

Valleys underlying many of the glaciers stay below sea level and extend much farther inland than previously suggested, so warm ocean currents that have migrated northward with the changing climate could eat away at the ice for much longer than current climate models suggest. “It will take much longer for these glaciers to lose contact with the ocean,” study author Mathieu Morlighem, of the University of California, Irvine, told Climate Central.

2. Melting Antarctica could devastate global food supply

A new report is the “first to factor in the effects of the slow-motion collapse of the Western Antarctica ice sheet on future food security.”

About time, I’d say.

The report acknowledges recent findings that that the retreat of the Western Antarctica ice sheet was unstoppable – and could lead to sea-level rise of up to 4 metres over the coming centuries.

“That sea-level rise would take out half of Bangladesh and mostly wipe out productive rice regions in Vietnam,” Nelson told The Guardian. “It would have a major effect on Egyptian agricultural areas.”

“A sea level rise of 3 meters (10 feet) over the next 100 years is much more likely than the IPCC thought possible,” the report said.

In terms of absolute land loss, China would be at risk of losing more than 3 million hectares (7.4 million acres). Vietnam, India, Bangladesh, and Myanmar could lose more than 1 million hectares (2.5 million acres), the report said.

The report recommends a radical increase in expenditure on agricultural research, which has been in decline everywhere over recent decades.

3. CSIRO cuts

The federal government cut CSIRO’s funding by $111 million over four years, which will result in 500 job cuts.

Dr Borgas [president of the CSIRO Staff Association] said a plan to move the Aspendale Laboratories to the organisation’s larger site in Clayton had been previously discussed but had come to nothing.

He said it was unclear whether the relocation would reduce the research performed by the 130 staff, which includes ice core analysis, air quality and pollution research and climate and atmospheric modelling.

Most countries planning for a future increase their scientific research funding.

4. CO2 levels decisively pass 400 ppm

During April all 12 World Meteorological Organisation northern hemisphere monitoring stations passed the 400 ppm mark, the first time ever. This is how such a level compares to the 800,000 year ice core record:

assets-climatecentral-org-images-uploads-news-5_2_13_news_andrew_co2800000yrs-500x282

When was it last this high? Possibly 15 million years ago, when it was warmer and there wasn’t much ice around.

“This was a time when global temperatures were substantially warmer than today, and there was very little ice around anywhere on the planet. And so sea level was considerably higher — around 100 feet [30 metres] higher — than it is today,” said Pennsylvania State University climate scientist Michael Mann, in an email conversation. “It is for this reason that some climate scientists, like James Hansen, have argued that even current-day CO2 levels are too high. There is the possibility that we’ve already breached the threshold of truly dangerous human influence on our climate and planet.”

5. Global temperature and CO2

I came across this graph from the NOAA National Climatic Data Center plotting CO2 levels against temperature rise. While correlation does not mean causation there is simply no alternative explanation.

assets-climatecentral-org-images-uploads-gallery-TVM-Global_Temp_and_CO2_web-600

If you take out 1998, which can be regarded as an outlier, the socalled ‘pause’ is only apparent from 2005, which is too short a time to mean anything.

There is another view which sees temperature responding in step-wise fashion. On that basis we may be due for another step, and with an El Niño likely…

Here’s one showing the ten warmest years on record, all since 1998:

1.Three reports

First, the Climate Change Authority released a Draft Report of its Targets and Progress Review.

I have a draft post in the bin, which I’ll publish after Easter. Labor are likely to adopt the enhanced targets it recommends, whereas the LNP have confirmed they won’t go beyond 5% by 2020.

Second, I’m working on a post on the IPCC’s second report in the current series, released on 31 March Impacts, Adaptation and Vulnerability. To get a head start you can follow the links from the report website.

I should be able to finalise the post for the week after Easter.

Third, the Summary for Policymakers of the IPCC’s third report Climate Change 2014: Mitigation of Climate Change was released on Monday. I hope to tackle it over Easter, aiming for publication the second week after Easter. The ABC has comment: politicians and Frank Jotzo and John Connor. The Carbon Brief has a lot of useful material.

2. The cost of mitigation

The IPCC mitigation report puts the cost of action at 0.06% of GDP, but calculating the cost is complex, especially when looking at the damage caused by doing nothing.

Researchers Rosen and Guenther find that the economic modelling is not possible, there are too many variables and too many unknowns.

Yet crisis trumps uncertainty, we have no real choice but to act.

3. Trouble in the vineyards

Early ripening is becoming a huge problem for growers and wineries.

growers say they’re having trouble processing their crop because it’s ripening too quickly.

Researchers are blaming climate change, with warmer conditions and drier soils accelerating the ripening process.

4. Microbes cause Permian–Triassic extinction?

The Permian–Triassic extinction event, commonly known as the Great Dying, was responsible for the extinction of roughly 90% of all life on Earth.

According to new research at MIT the event may have been caused by microbes.

The team’s research indicates that the catastrophic event was in fact triggered by the tiniest of organisms, a methane-releasing microbe called Methanosarcina. New evidence suggests that at the time of the extinction, the microbes appeared in massive numbers across the world’s oceans, spreading vast clouds of the carbon-heavy gas methane into the atmosphere. This had the effect of altering the planet’s climate in a way that made it inhospitable to most other forms of life inhabiting Earth at that time.

5. Land clearing returns to Qld

According to The Wilderness Society the Queensland Government has approved the clearing of 30,000 hectares at Strathmore Station in the Gilbert River catchment in the Gulf country, which will add the equivalent of 4.2-6.6 million tonnes of carbon dioxide into the atmosphere, the same as running up to another 2.6 million cars on our roads.

Strathmore wants to clear another 70,000 hectares. Together with another proposed Gilbert River project, IFED’s so-called Etheridge mega farm, the two schemes would clear and flood 200,000 hectares of land.

That would be like bulldozing a 10km wide strip for 200km.

6. Instruments of persuasion

Dr Rod Lamberts of the Australian Centre for Public Awareness of Science at the ANU says it’s time to dump science and facts as instruments of persuasion in favour of advertising and marketing. He says we need to appeal to people’s emotions, which will

have a stronger effect than trying to appeal to their brains via some kind of, you know, fact channel.

But please note, the facts are needed to support the campaign:

If the goal is to affect change, then I believe we need to step more into the realms of advertising and marketing and so on, in terms of delivering messages that are supported by what the science is telling us, but don’t have the science in those messages. (Emphasis added)

Jane Caro agrees on the need for a different approach:

Facts have never changed anyone’s mind about anything, sadly. It’s very hard for scientists to understand this, because they’re highly rational people, but in actual fact, no-one has ever been rationalised out of a belief.

There are only two things that change people’s attitudes and behaviour, particularly their behaviour, and they’re two emotions, and they’re hope and fear.

Again, facts and the science are surely needed to rationalise a changed belief. Beliefs need reason to support them.

Who mounts and pays for an advertising and marketing campaign? We look to governments, but in Australia they are the actual problem.

7. Direct Action less popular than the price on carbon

Meanwhile Essential Media Communications have done a survey of opinion that shows Direct Action distinctly less popular than the price on carbon. In terms of age, there is a tipping point beyond which the doubters predominate and it’s age 55. Abbott’s climate policy may come back to bite.

as the flat-earthers take control of the Federal Government, more Australians than ever have come to the conclusion that the Earth is in fact round.

Changing our policymakers seems the best way home but then Labor needs to offer more than tokenism. In my opinion Labor politicians should be the prime target group. The current mob won’t change without a spell in opposition and transformational ideological renewal.

Climate clippings_175 This is a continuation of the Climate clippings series familiar to readers of Larvatus Prodeo

While this edition was finished about a week ago I actually started writing stuff from about mid-February and have several others queued in the draft bin. They’ll be fed in periodically at the rate of perhaps more than one a week until I catch up with myself.

1. Strong El Niño rated an 80% chance

That’s according to Paul E. Roundy of the University at Albany, New York.

The sub surface temperature of the eastern Pacific Ocean is measuring an ‘astounding’ six degrees warmer than normal for this time of year.

The only time anything similar has happened was in March 1997, before the whopping 1998 El Niño.

An El Niño normally means dry conditions and reduced monsoons in Australia and Indonesia, but wetter weather in Central America.

Climate Progress shows this interesting graph:

gistemp_nino_s-600

Since 1998 there have been six La Niña years warmer than any El Niño years prior to 1998.

At Mashable Andrew Freedman quotes the same people but found at least one scientist who thinks there’s perhaps a 40% chance there will be no El Niño at all.

Worth watching. Could be spectacular.

2. Wave and tidal energy

Climate Progress reports on wave energy projects at Morro Bay in California and elsewhere.

A 2012 report prepared by RE Vision Consulting for the Department of Energy found that the theoretical ocean wave energy resource potential in the U.S. is more than 50 percent of the annual domestic demand of the entire country. The World Energy Council has estimated that approximately 2 terawatts — 2 million megawatts or double current world electricity production — could be produced from the oceans via wave power.

3. The Pacific Ocean is turning sour

Much faster than expected, according to a new study.

Apparently CO2 concentrations are not uniform around the world and the tropical Pacific is getting more than its fair share. Hence the ocean in that area is acidifying faster than elsewhere.

4. Oxfam on food futures

From Huff Post, Oxfam has just completed a report (downloadable here) which suggests that climate change could delay the fight against world hunger for decades. Global food prices could double by 2030, with half the increase attributable to climate change. In the next 35 years there could be 25 million more malnourished children under the age of five than there would otherwise be.

Oxfam analyzed ten gaps that measured how prepared – or unprepared – 40 food-insecure countries are to tackle climate change impacts.

We assess ten key factors that influence a country’s ability to feed its people in a warming world – these include the quality of weather monitoring systems, social safety nets, agricultural research and adaptation finance.

As expected, the poorer countries will be most affected.

5. Will we still be able to have a decent cup of tea?

At the foot of the Huff Post Oxfam link above is a graphic showing the top “endangered” crops listing in order chocolate, coffee, beer (at least in Germany), peanuts, durum wheat to make pasta in Italy, maple syrup, honey, wine (at least in France). It must be said that I couldn’t find that list in the Oxford report which is mainly about staples such as rice and vegetables.

Now it seems that Assam tea is being affected by hotter, drier weather with more erratic rainfall. Indeed tea growing all over the world is becoming more difficult.

There’s more at the BBC.

6. More on global food security

A separate study found that from 2030 onwards, the world’s crop yields will be more and more impacted by climate change.

The study found that Sub-Saharan Africa and South Asia showed significant yield reductions for the second half of the century, while regions of the world with temperate climates, such as Europe and most of North America, could withstand a couple of degrees of warming without a noticeable effect on harvests, or possibly even benefit from a bumper crop.

One of the most important findings of this study is that adaptation may not be as effective for rice and maize as it is for wheat.

7. On the other hand

If you need a more cheerful story, here’s one about peasant farmer Vu Thi Ngoc who has adapted to crazy weather in the uplands of northern Vietnam by growing a different range of crops and changing farming practices.

It shows adaptability at work, this time with the help of CARE and Vietnam’s Agriculture and Forestry Research and Development Centre for the Northern Mountainous Region.

1. SAM and ENSO divorce

Roger Jones at Understanding Climate Risk has a post on global warming breaking the link between SAM and ENSO, with consequences for our weather.

To help, GMT in the graph means ‘global mean temperature’.

wang-cai-fig-3_500

With the global warming signal taken out (top panel), the relationship between ENSO and SAM is strong but with it in, they depart in the late 1960s (lower panel).

There’s also an article in The Age.

From Jones:

So what does this mean for Australia’s climate? It means that an overwhelmingly positive SAM is keeping the westerlies south and contributing to our drier autumn winters and delivering weather typical of the Riverina to southern Victoria according to Cai. Recovery of the ozone layer and reduction in greenhouse gas emission would stabilise this process, rather than continuing to send it south.

In summer it also allows the easterly trades greater access, bringing in more moisture from the tropics and enhancing La Niña summer rainfall. Continue reading Climate clippings 79
