Under threat: The village of Fairbourne in west Wales is to be left to the mercy of the sea under council plans which campaigners from the area are opposed to

  • Villagers furious over plans to abandon sea defence maintenance for the picturesque village of Fairbourne, Wales 
  • They say property prices have nose-dived and businesses are struggling because the village could be left to the sea
  • Campaigner says the plans are based on ‘aggressive’ sea level forecasts which don’t take into account other views 
  • Residents are trying to pay for legal action to review the council plans and want compensation if they are moved

Residents of a Welsh coastal resort have been left trapped in their homes by council plans to abandon sea defences and allow their village to be swallowed up by the sea.

People living in picturesque Fairbourne in Cardigan Bay are digging in for a bitter legal battle against plans to ‘decommission’ their village and flood their streets with sea water.

They are fighting the plans they say are based ‘nonsensical’ predictions and demanding compensation over moves to move them.

”CARTOON CLIMATOLOGY” REVISITED: SCIENCE MISREPRESENTED…….

Climate science misrepresented

By Jim Whiting
December 18, 2015

“Shakespeare made a reckless ruler pull down his kingdom on his head, [and we are adding] a hundred and twenty excess parts per million of carbon dioxide in our atmosphere.”

But it is generally acknowledged that it’s horrifyingly ignorant to think that we can dial in a nice climate by turning the CO2 adjustment knob.  Indeed, the current and projected CO2 levels are at the very low end of the range for the last 600 million years.  Global temperature is also at the low end of that range.  More recently, we are at the low end of the temperature decline since the Holocene Optimum 8,000 years ago.  Backing up, the Eemian age 120,000 years ago was much warmer, and sea levels were 6 meters higher, and CO2 was around 280 ppm.

What is obvious is that the Earth will do exactly as it pleases, and we have no ability to predict that or, consequently, to control it.  We can influence it, usually but not always for the worse.  Furthermore, we have no idea if the current 15°C is the optimum climate.  Higher temperatures over the last 200,000 years have been associated with improvements in human welfare.  There has been no tipping point, not even at the P-T Extinction Event 250 million years ago, when the temperature briefly blipped past the previous 22°C lid (in effect for hundreds of millions of years) to at least 28°C.  More interestingly, there has been no tipping point on the downside, when Snowball Earth increased the albedo so drastically.

FINNISH ENVIRONMENT MINISTER CROWS OVER GLO-BULL WARMING CRONY BUSINESS WELFARE EXPANSION……..

Fake free market racketeers. You can bet that the overwhelming amount of these businesses will be infused with public money. 

If there was a natural market based demand for “green technology” (outside of big government forcing legislation down people’s throats) then I wouldn’t be suspicious of the call for the expansion of that new market. But this is fake “cartoon climatology” with big crony business driving the push in order to get their hands on more public money that should be in the people’s hands, not in their pockets.

NOTE: This is all artificially generated, a boondoggle, and the consumer/taxpayer will get stuck with the bill in the end. All it’s going to take is a conservative Republican in office, rejecting glo-bull warming as a fraud, and the whole enterprise will come crashing down on its head. The Indians and Chinese don’t believe in it, and will applaud its demise. Mark my words.

Finnish environment minister, experts: Climate deal to boost cleantech industry

The Paris Agreement could create tens of thousands of jobs in Finland, say Environment Minister Kimmo Tiilikainen and analysts of the burgeoning cleantech sector.

Environment Minister Kimmo Tiilikainen, who led the Finnish delegation at the COP21 Paris climate conference, has described this weekend’s Paris Agreement as “pivotal”. He told Yle on Monday that biggest significance of the deal for Finns will be that responsibility for combating climate change will now be shared more evenly among various countries.

“We can breathe a sigh of relief because the rest of the world is now joining in on this. This is not just the EU’s hobby that brings costs, but now rather the opening of opportunities,” the Centre Party politician said in a TV interview.

He pointed out that Finland boasts the kinds of cleantech companies that are now in demand.

Thousands of jobs to come?

The Paris Agreement could create tens of thousands of jobs in Finland, say experts such as Markku Ollikainen, Professor of Environmental Economics at the University of Helsinki.

Most of these are expected to be in the industrial sector and the first of those, a couple of thousand, are likely to be created in cleantech companies producing bio-fuels or other products based on bio-technologies.

Ollikainen predicts that Finland’s competitive position will improve. He foresees a turn-around in exports, saying that it is “rock solid” that the Paris Agreement will create demand for cleantech products.

EU climate agreements have already focused attention on cleaner technologies. China and other low-wage competitors will see costs rise as they push to catch up. Being already well advanced, Finnish companies are well placed to compete in a new kind of global market.

Industrial leaders are also confident that the deal will create demand and jobs.

They see Finland as having a head start in essential sustainable technologies.

“Markets practically limitless”

“The markets that are opening up are practically limitless and the growth coefficients are amazing,” says Tiina Kähö, who leads the Carbon-neutral Industry section at the Finnish Innovation Fund Sitra. “Now it’s important for corporations and the state to work together. Soon there will be a tough race on the world markets.”

Jouni Keronen, CEO of Finland’s Climate Leadership Council, says that Finland has a lot of cleantech know-how and technology, but that it must make more effective use of new inventions. “

Finnish firms “can take advantage of new markets by offering solutions early on,” says Keronen.

The GOP Don’t Never Dance With Them What Brung Them

by Mark Steyn
Steyn on America

[…]

Also absent was Cory Gardner, the Colorado Republican. Daines tossed a friendly pitch for his home-state audience, with amusing references to some pal of his re-charging his Tesla in Bozeman. And, when he was done schmoozing for Eyewitness News in Bozeman, he left the room. So, for the remaining 70 per cent of the hearing, what should have been six Democrats and seven Republicans was instead six Democrats and one Republican – the lonely chairman, Ted Cruz. That’s why the Dems got 85 per cent of the question time and lobbed puffballs at Rear Admiral Titley – until eventually Judith Curry and I chose to push back at the fatuous Markey.

Why did this happen? I’m a foreigner, and I certainly rarely feel more foreign than when I’m in the ghastly US Senate. But I’ve attended committees in the Canadian parliament and other parts of the Commonwealth and can’t recall any occasion when the majority party’s members have chosen to boycott the hearing.

Why did no Republicans show up? Rubio was off campaigning in California and ignoring all those senatorial duties his constituent Jeb! wants him to focus on. But Thune and the rest of those guys were all in the building, voting on various Senate flim-flam going on that day. So even though they were 90 seconds away they chose not to attend.

The not so subtle reason is that, like Bob Dole (currently threatening, if Cruz is the nominee, to “oversleep” on Election Day), their antipathy to Ted Cruz outweighs everything else. Dole feels that Cruz has been given the greatest honor any man can have – the keys to the Senate men’s room – and yet he won’t play by the rules of the club.

The slightly subtler reason is that these Republicans felt that the whole climate biz was a bit of a hot potato for them. Yet, putting aside my own presence, the three scientists in the room were among the most respectable figures in the field: John Christy is the great innovator who developed the world’s first satellite temperature record; Judith Curry, among the old boys’ club of climate science, is perhaps the most distinguished female climatologist on earth, although she would disdain such a categorization; and Will Happer is an eminent Princeton physics professor garlanded with almost all the major awards in his field.

All of them have paid a price for speaking out against Big Climate. So, in disdaining Cruz (and/or me), senators Thune, Rubio, Moran, Sullivan and Gardner were also disdaining some of the most distinguished climate realists on the planet. Those three scientists did not deserve that from a handful of political hacks. Indeed, by their absence, they were contributing to the overall message of climate conformism: If you disagree with the “97 per cent consensus”, at least have the good taste to crawl away and die somewhere far off out of sight.

Think Tank: Paris Global Warming Agreement Is ‘Paper Tiger’

Environmentalists hold a banner which reads,

The energy industry is already saying Saturday’s Paris global warming agreement is “unenforceable, underfunded, and non-binding.”

“There is nothing historic about this deal,” said American Energy Alliance President Thomas Pyle in an email to the Daily Caller News Foundation. “The Obama administration clearly doesn’t have the support of Congress or the American people—making the agreement nothing more than a paper tiger. Unfortunately, this won’t stop the president from pursuing a domestic climate agenda that will raise energy prices on American families, but will have no impact on the climate.”

The Obama administration states that the deal will encourage nearly 200 countries to reduce carbon dioxide emissions, slowing global warming. Despite the doubt, President Obama is already celebrating the deal, as shown by the Tweet below.

One-third of Man’s entire influence on climate since the Industrial Revolution has occurred since January 1997. Yet for 224 months since then there has been no global warming at all (Fig. 1). With this month’s RSS temperature record, the Pause sets a new record at 18 years 8 months.

FMI chief: Paris 1.5 degree goal unrealistic

Many countries at the Paris climate summit opted to pursue a maximum global warming limit of 1.5 degrees Celsius instead of the originally proposed 2-3 degrees. Finnish Meteorological Institute director Petteri Taalas says the goal is not an easy one to reach.

Chief of the Finnish Meteorological Institute, Petteri Taalas went on Yle’s morning show to discuss the Paris climate summit. He said that the 1.5 degrees Celsius goal for an overall global warming upper limit will not be easy to reach.

“Honestly it isn’t very realistic,” Taalas said. “But it’s good that decision-makers are prepared to challenge the nearly 3-degree rise at which current measures would see warming halt.”

Video: Earth is actually growing greener

This week’s Conversation that Matters features Freeman Dyson a professor emeritus of the Institute for Advanced Study who says models do a good job of helping us understand climate but they do a very poor job of predicting it.

Dyson says, “as measured from space, the whole earth is growing greener as a result of carbon dioxide, so it’s increasing agricultural yields, it’s increasing the forests and it’s increasing growth in the biological world and that’s more important and more certain than the effects on climate.”

He acknowledges that human activity has an effect on climate but claims it is much less than is claimed. He stresses the non-climate benefits of carbon are overwhelmingly favourable.

On The Eve Of COP21 Paris Talks: World Just Doesn’t Care About Global Warming Any More

The world is losing interest in “global warming” a survey has found on the eve of the UN’s COP21 climate talks in Paris.

Most people in most of the 20 countries surveyed say they don’t want their leaders to set ambitious climate targets.

Fewer than half describe climate change as a “very serious” problem.

The survey, conducted by GlobeScan for the BBC, could scarcely have come at a worst time for the global environmental movement. After the disastrous failure of the last major climate conference in Copenhagen in 2009, they have been pulling out all the stops to make the talks which begin in Paris next week a success.

Earlier this year UN Secretary General Ban Ki-Moon flew to the Vatican to enlist the Pope’s support; President Obama has declared that there is “no greater threat” than climate change; John Kerry, Hillary Clinton, Sen. Bernie Sanders (I-VT) 16% and the Prince of Wales have all said it’s worse than terrorism; the National Oceanic and Atmospheric Administration (NOAA) has helped out by erasing “the Pause” in global warming; the IUCN has magicked up a study claiming the doing-just-fine polar bears are in trouble….

President pledges to cut carbon footprint

Like hundreds of other Finns, President Sauli Niinistö has signed an online pledge to take steps to reduce his personal carbon footprint by half within ten years.

In part, the purpose of the pledge is to send a clear message to world leaders to reach agreement that will stabilize the global climate system and reduce the harmful effects of climate change.

President Niinistö says that be started reducing his own personal carbon footprint several years ago.

“It began when we installed a geothermal heat pump in our home,” explains Niinistö.

The president has also switched to emissions-free electricity and the increased use of LED lighting. He says that he now also intends to make sure that as little food as possible in his household goes to waste.

The president is encouraging more of his countrymen to sign the pledge to cut their own carbon footprints.

President Niinistö will be heading Finland’s delegation to the United Nations Climate Change Conference that begins in Paris on Monday.

“All bathtubs should be banned. Just imagine it!”, he exclaimed in an interview published in the Svenska Dagbladet newspaper on Saturday.
Carl XVI Gustaf said that the idea had come to him the day before the interview, as he was going through his morning routine and was forced to run a bath, because the room in which he was staying lacked a shower.
“It took a lot of fresh water and energy,” he said. “It struck me so clearly: it’s not wise that I have to do this. I really felt ashamed then, I really did.”
Later in the interview, he cautioned that the suggestion was a little “lighthearted”.
“But there is a truth there,” he maintained. “Those small details have an enormous effect.”

GLO-BULL WARMING DEBUNKING: COLD SUN RISING…….

 But first, Henrik Svensmark’s documentary on climate change and cosmic rays. (IMPORTANT)

But that’s not the only cooling effect of a solar minimum. A dim sun doesn’t deflect cosmic rays away from Earth as efficiently as a bright sun. So, when these rays enter our atmosphere, they seed clouds, which in turn cool our planet even more and increase precipitation in the form of rain, snow and hail.

Cold sun rising

New studies flip climate-change notions upside down

The sun will go into “hibernation” mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society’s annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it – the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova’s model is said to have near-perfect accuracy.

So what is a “solar minimum”?

Our sun doesn’t maintain a constant intensity. Instead, it cycles in spans of approximately 11 years. When it’s at its maximum, it has the highest number of sunspots on its surface in that particular cycle. When it’s at its minimum, it has almost none. When there are more sunspots, the sun is brighter. When there are fewer, the sun radiates less heat toward Earth.

But that’s not the only cooling effect of a solar minimum. A dim sun doesn’t deflect cosmic rays away from Earth as efficiently as a bright sun. So, when these rays enter our atmosphere, they seed clouds, which in turn cool our planet even more and increase precipitation in the form of rain, snow and hail.

Scientists at the Climate and Environmental Physics and Oeschger Centre for Climate Change Research at the University of Berne in Switzerland have recently backed up theories that support the sun’s importance in determining the climate on Earth. A paper published last year by the American Meteorological Society contradicts claims by IPCC scientists that the sun couldn’t be responsible for major shifts in climate. Judith Curry, chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, rejected IPCC assertions that solar variations don’t matter. Among the many studies and authorities she cited was the National Research Council’s recent report “The Effects of Solar Variability on Earth’s Climate”.

Other researchers and organisations are also predicting global cooling – the Russian Academy of Science, the Astronomical Institute of the Slovak Academy of Scientists, the Institute of Terrestrial Magnetism Russia, Victor Manuel Velesco Herrera at the National University of Mexico, the Bulgarian Institute of Astronomy, Dr Tim Patterson at Carleton University in Canada, Drs Lin Zhen at Nanjing University in China, just to name a few.

Mass gains of Antarctic Ice Sheet greater than losses, NASA study reports

NASA study: Mass gains of Antarctic Ice Sheet greater than losses

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

According to the new analysis of satellite data, the Antarctic ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed to 82 billion tons of ice per year between 2003 and 2008.

“We’re essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica,” said Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published on Oct. 30 in the Journal of Glaciology. “Our main disagreement is for East Antarctica and the interior of West Antarctica – there, we see an ice gain that exceeds the losses in the other areas.” Zwally added that his team “measured small height changes over large areas, as well as the large changes observed over smaller areas.”

Scientists calculate how much the ice sheet is growing or shrinking from the changes in surface height that are measured by the satellite altimeters. In locations where the amount of new snowfall accumulating on an ice sheet is not equal to the ice flow downward and outward to the ocean, the surface height changes and the ice-sheet mass grows or shrinks.

But it might only take a few decades for Antarctica’s growth to reverse, according to Zwally. “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years—I don’t think there will be enough snowfall increase to offset these losses.”

Arctic snow not darkening due to soot, dust, study finds

Arctic snow not darkening due to soot, dust, Dartmouth-led study finds
Dartmouth Adjunct Assistant Professor Chris Polashenski and his colleagues found that degrading satellite sensors, not soot or dust, are responsible for the apparent decline in reflectivity of Arctic snow. Credit: Chris Polashenski

For millennia, Greenland’s ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surface melting to accelerate. Some studies suggest this “dirty ice” or “dark snow” is caused by fallout from fossil fuel pollution and forest fires.

But a new Dartmouth-led study shows that degrading satellite sensors, not soot or dust, are responsible for the apparent decline in of inland across northern Greenland. The study’s results suggest the ice sheet hasn’t lost as much reflectivity as previously thought, and that black carbon and dust concentrations haven’t increased significantly and are thus not responsible for darkening on the upper ice sheet.

The findings, which contradict anecdotal observations and earlier scientific studies, appear in the journal Geophysical Research Letters. A PDF of the study is available on request.

Observations suggest the Greenland Ice Sheet’s albedo – or its ability to reflect the sun’s energy back into the atmosphere—has declined considerably since 2001 due to black carbon and dust from increased industrialization and across the northern hemisphere. The apparent decline is greatest around the ice sheet’s edges, but it also is occurring in the high elevation interior known as the dry snow zone, where the reflectivity is effectively reset each winter by new snowfall.

Two properties dominate reflectivity in dry snow – the size of snow grains, which become larger and more absorbent as they melt, and the presence of dark impurities that absorb the sun’s energy, predominantly black carbon and mineral dust, which also cause the snow to melt faster. Snow high on the Greenland Ice Sheet typically has black carbon concentrations too low to significantly affect its reflectivity, but in 2012 large wildfires in Canada and Siberia and favorable winds may have combined to trigger record surface melting of the ice sheet that year.
