SURVEY ON PUBLIC KNOWLEDGE AND ATTITUDE TO CLIMATE CHANGE AND THE SEA

SURVEY ON PUBLIC KNOWLEDGE AND ATTITUDE TO CLIMATE CHANGE AND THE SEA

This large survey looks at how the public perceives the effect of man’s behaviour on the sea. Having read it I believe it goes beyond "climate change", as it lumps together pollution (such as effluent etc.) along with CO2. I am not convinced that surveys like this are very accurate, but they are still interesting in a general way. Worth reading in full if you have the time.

It throws up some positives such as "54% of European citizens believe that humans play only a partial role or no role in climate change."

Many who thought that they were well informed on the impacts of climate change on the ocean believe scenarios that may happen by 2100 if we do not reduce greenhouse gas emissions have already occurred e.g. loss of Arctic sea-ice in the summer (26% of respondents) and sea temperature increases of more than 2°C (30% of respondents). I am not surprised given the media coverage.

WSJ Blows It on Australia’s Power Crisis (intermittent resources, not fossil fuels, at fault)

“The blackout in South Australia that left the entire province without electricity for more than 24 hours was caused by too great a reliance on wind energy, coupled with the closing of the areas last coal-fired power plant.”

While the Wall Street Journal’s editorial page retains a free market, limited government outlook, the body of the paper continues to move left, following much of the media.

The July 11, 2017, WSJ article on Australia’s energy problems, “How Energy-Rich Australia Exported Its Way Into an Energy Crisis,” with the subtitle “The world’s No. 2 seller abroad of liquefied natural gas holds so little in reserve that it can’t keep the lights on in Adelaide—a cautionary tale for the U.S.” laid blame on LNG exports rather than relying on intermittent electricity sources.

The print edition had the title: “The Energy Shortage No One Saw Coming.” Well, Francis Menton at Manhattan Contrarian warned of just what happened in an October 6, 2016, article, “Pay Attention to South Australia.” And see his update last week in specific reference to the WSJ article, “Wind and Solar Power Don’t Work.”

Author Rachel Pannett, Deputy Bureau Chief of the Wall Street Journal’s Sydney bureau, is obviously no energy expert. She missed a lot.

The Real Problem

Australia’s energy problems flow not from free market processes but interventionist energy policies adopted by the Labor and Liberal parties. Their energy policies had three critically important results:

  1. Expanding wind and solar energy to the exclusion of using fossil fuels, by using subsidies to underpin the development of wind farms
  1. Closing coal-fired power plants to stop CO2 emissions
  1. Prohibiting the development of natural gas in the Southeast portions of Australia, primarily New South Wales and South Australia

These are the three real causes of Australia’s energy problems, not the actions of industry in developing Australia’s LNG exports.

The blackout in South Australia that left the entire province without electricity for more than 24 hours was caused by too great a reliance on wind energy, coupled with the closing of the areas last coal-fired power plant.

The 2014 report issued by the Australian Energy Market Operator Ltd (which operates the national energy market) & Electranet (which operates the national electricity transmission grid) predicted that South Australia would suffer blackouts if it continued with its decarbonization policies.

Figure 1. South Australia Without Electricity

The Hazelwood, Victoria, 1,600 MW coal-fired power plant is also being closed, removing 20% of Victoria’s baseload capacity and 5% of Australia’s.

In spite of the obvious problems, the Labor government in South Australia continues to push wind energy with a goal of having wind provide 50 percent of the province’s electricity.

Now that industry is laying off workers and closing plants because of the lack of low-cost natural gas, the national government is taking action … But the actions are short sighted if the real causes of Australia’s energy disaster aren’t addressed.

At the national level, the Liberal Party, under Prime Minister Turnbull, has enacted legislation to curtail exports unless the LNG industry brings natural gas to those parts of Australia that lack sufficient supplies.

While these regulations may be needed in the short term, and are politically expedient, they will only exacerbate Australia’s energy problems unless the root causes are addressed, i.e., too much wind and solar, too few coal-fired power plants and not allowing the development of new natural gas supplies in those parts of Australia lacking sufficient supplies.

My Trip to Australia

On my trip to Australia in February, our group met with former Prime Minister Tony Abbott, who, in his talk and Q&A sessions, made it clear that Australia’s energy problems were rooted in a misguided effort to cut CO2 emissions coupled with deliberately ignoring Australia’s huge resources of coal and natural gas.

His views are essentially summarized by the three problems cited above.

Greenpeace and other extreme environmental groups have successfully imbued Ausrtralians with a fear of global warming from CO2 emissions. Greenpeace has, for example, campaigned to close coal-fired power plants.

As far back as 2011 Greenpeace, with the generous support of the Rockefeller Family Fund, proposed “A strategy to disrupt the Australian Coal Boom.” They have obviously had considerable success.

These are the facts about Australia’s predicament that should be reported by the media, not a hit-piece about the selfish, money-grubbing intransigence of the LNG industry.

This isn’t the first time the Wall Street Journal has abandoned conservative positions.

The media’s misrepresentation of facts is becoming a national disgrace.

It’s becoming clear that Australia, rather than Germany, could become the poster child for the harmful effects of renewables. See, Blackout Race Underway.

There have been far bigger Antarctic icebergs than the latest A68 Larson C berg

CNN is  “freaking out” about the latest large iceberg. But John Sutter doesn’t mention that there was an iceberg twice its size in the year 2000 which was 11,000km2, and that as long ago as 1967, two other icebergs of a similar size were recorded. Thanks to John McLean for the links.

When it comes to long term trends in iceberg sizes, the only scientific answer is “who knows”. Satellite records are so short, if a bigger iceberg broke off in say, 1811, how the heck would we find out? Not much is left of an iceberg 100 years later. What kind of proxy could show it ever existed — ancient stone carvings of satellite pics from ancient Greece?

The latest 2017 Larson C iceberg is 5,800 square kilometers and weighs a “trillion tons”. But back in 1967, two icebergs calved – one of 7,000km2 and one of about 5,000 km2:

Swithinbank (1969), basing on analysis of the ESSA-3 satellite imageries, reports that in 1967—68 two giant icebergs were seen in the eastern part of the Weddell Sea, measuring 70 by 100 km, and 45 by 100 km respectively, with total area of about 11.000 km.
