A few Arctic sea ice myths get exploded in this BBC report:

The volume of Arctic sea ice increased by around a third after an unusually cool summer in 2013. Researchers say the growth continued in 2014 and more than compensated for losses recorded in the three previous years.

The scientists involved believe changes in summer temperatures have greater impacts on ice than thought. But they say 2013 was a one-off and that climate change will continue to shrink the ice in the decades ahead.

Climate talks ‘flagging’ ?[image credit: The Clinic]


Usual story – rich and poor countries fighting about money. Things are so bad, they need a pre-conference conference to try and figure out what they’re going to say and do at the real conference, apart from wave ‘projections’ and ‘scenarios’ at each other. Or – anyone fancy a trip to Paris in July?

Foreign and environment ministers and other high-level officials from 45 countries are set to gather in Paris Monday seeking to re-energise climate talks mired in technical details and political squabbling, reports Yahoo News.

Are these people just mind-bogglingly naive, downright dangerous – or something else? You decide. And for the record we don’t support the ‘scientific consensus’ claim in this Mercury News report:

A team of elder Silicon Valley scientists is building an audacious device that might solve one of humanity’s most profound dilemmas — a “cloud whitener” designed to cool a warming planet.

The men — retired physicists, engineers, chemists and computer experts from some of Silicon Valley’s top tech companies — have been meeting four days a week for seven years in the Sunnyvale lab of the Marine Cloud Brightening Project to design a tool that creates perfectly suspended droplets of water resembling fog.

Let’s see if this new paper in the same journal as the ‘what hiatus?’ effort gets the same level of publicity as the other one, given that ‘Nieves et al…find substantially less warming in the top 100 m of the oceans in the current decade than in the previous one.’

If there is one topic that illustrates the state of climate science it is that of the so-called “pause” or hiatus – the observational fact that global surface annual average temperatures, as well as satellite data on the lower troposphere, hasn’t changed for a decade or more.

The US President seems to be doing a Lord Nelson, turning a blind eye

President Obama says that global warming is the biggest problem Earth has ever faced, based on the opinion of about three or four flaming morons he considers to be the world’s top scientists. He also says he doesn’t have time to debate the “Flat Earth Society” – which by his definition would include this guy.

In 2008, Dr. Ivar Giaever joined over 70 Nobel Science Laureates in endorsing Barack Obama for president, but seven years later the Nobel Prize winner now stands against the president on global warming.

“I would say that basically global warming is a non-problem,” Giaever, who won the Nobel for physics in 1973, told an audience at the Lindau Nobel Laureate meeting earlier this month.

Giaever ridiculed Obama for stating that “no challenge poses a greater threat to future generations than climate change.” The physicist called it a “ridiculous statement” and that Obama “gets…

Daily Media Review cuts through the headlines and scare stories to point out some of the key fallacies and failed assumptions relied upon by the climate change scare industry.

The mainstream media love to lecture us daily about the coming apocalypse as a result of catastrophic climate change, but are we being told the complete story?

Two choices: whether to laugh or cry at the latest fortune-telling exercise from NASA’s warming-obsessed spin-doctors. Climate models are famed for their predictive inadequacy – incompetence even – so this looks exactly like an exercise in futility.

NASA has released a dataset setting out how rainfall and temperature patterns are likely to change in the coming decades, Gizmag reports. The data covers 21 climate models, mapping how our environment could change due to growing concentrations of greenhouse gases in the atmosphere.

In 2003, two proper scientists wrote a paper on the climate of the Faroe Islands, which lie between Iceland and Norway.

They published this graph of air temperatures at the capital Torshavn.

And commented:

So we find confirmation of the 1925-40 warm period, and that the recent temperature rise is no more than a natural recovery from the colder 1950-80 interval.

Of course, temperatures may have risen since 2003, but the raw GISS data shows otherwise.

Below is their graph based on the raw GHCN V2 temperatures, as they appeared in 2011. (The warmest year was 2003 itself).

It has not taken long for the left wing press to attack the investigation into the integrity of global temperature records!

The UK’s most prominent climate change denial group is launching an inquiry into the integrity of global surface temperature records.

The Global Warming Policy Foundation (GWPF), established by notable climate-change sceptic Lord Lawson, announced an international team of “eminent climatologists, physicists and statisticians” would investigate the reliability of the current data.

Professor Terence Kealey, the former vice-chancellor of the University of Buckingham, has been appointed chair of the international temperature data review project.

Professor Kealey studied medicine at Oxford University before lecturing on clinical biochemistry, which is primarily concerned with the analysis of bodily fluids, at Cambridge University. It is unclear what experience he has in the field of climate change.

The other five commissioners of the data review project: Petr Chylek, Richard McNider, Roman…

While we may not yet have reached the “point of no return”—when no amount of cutbacks on greenhouse gas emissions will save us from potentially catastrophic global warming—climate scientists warn we may be getting awfully close.

Have We Passed the Point of No Return on Climate Change? – Scientific American

This sounds bad, but is actually excellent news. In 1989 they only gave us until the year 2000 to stop global warming, so this is actually quite a nice reprieve.

The Guardian newspaper finally facing up to climate reality? Well, after a fashion. Their global warming can may have been kicked down the road for a while, that’s all.

The idea that natural variation could make temperatures go up as well as down is still not for discussion in their biased climate world.

H/T Lord Beaverbrook.

Guardian report: Manmade global warming over the past decade has probably been partly offset by the cooling effect of natural variability in the Earth’s climate system, a team of climate researchers have concluded.

The finding could help explain the slowdown in temperature rises this century that climate sceptics have seized on as evidence climate change has stopped, even though 14 of the 15 hottest years on record have happened since 2000.

The authors of the new paper describe the slowdown, sometimes called a global warming hiatus or pause, as a “false pause”. They warn that the natural cycles in the Pacific and Atlantic that they found are currently having an overall cooling effect on temperatures will reverse in the coming decades – at which point warming will accelerate again.

AN OPEN LETTER TO THE PRIME MINISTER ABOUT CLIMATE CHANGE AND ENERGY POLICIES

Dear Prime Minister,

Like you I read PPE at Oxford and I was lucky enough to be taught Economics by Professor Wilfred Beckerman. He has an interest in the economics of environmentalism, having worked in that field with the World Bank in the 1960s, advised the Labour Party on it and he was a member of the Royal Commission on Environmental Pollution from 1970 to 1973. He wrote an excellent book in 1974 called “In Defence of Economic Growth” which was a rebuttal of the famous Club of Rome 1972 book “The Limits to Growth”.

In 2002, Prof. Beckerman published a book called “A Poverty of Reason: Economic Growth and Sustainable Development”. If you or your advisers on environmental policies haven’t read it before, I thoroughly recommend it as a succinct and massively sensible analysis of many environmentalists’ arguments by a brilliant economist and excellent teacher. He is still going strong at 87; he’s still teaching at UCL, mainly on ethical issues in Economics which he touches on in this book when addressing the mistakes made by many environmentalists about intergenerational ethics, rights and basic economics when considering issues like resource depletion, climate change and the precautionary principle.

One of the ‘Tablets of Stone’ in the argument for ‘Anthropogenic Global Warming’ is that human emission of co2 through the burning of fossil fuel is responsible for the increase in the atmospheric level of this trace gas since pre-industrial times, which now constitutes 0.039% of Earth’s atmosphere. It is claimed that this can be logically deduced and calculated and  there is no doubt we are the guilty species.

But there’s a problem…

Roy Clark phd has spent the last three years researching and writing this paper. It confirms my own research on the average sunspot number and the ocean equilibrium value, as well as extending my thoughts on the multi-decadal retention of heat energy in the worlds oceans into properly quantified analysis. This has enabled Roy to make much more detailed and definite statements about the relative importance of co2 in the atmosphere as an agent of climate change than I could. The paper is pay for, but at least the journal (Energy and Environment) has been consistently open minded about reviewing and publishing those scientists whose research findings are sometimes at odds with the so called mainstream consensus on this issue. The paper runs to 30 pages with many graphs and digrams and represents much better value and more bang for your buck than any other published paper on the subject I know of.  A version of the CA climate article should be published on the SSPI (Science and Public Policy Institute) website quite soon and I will revisit this paper after that has gone online.

Abstract:

Energy transfer at the Earth’s surface is examined from first principles. The effects on surface temperature of small changes in the solar constant caused by the sunspot cycle and small increases in downward long wave infrared (LWIR) flux due to a 100 ppm increase in atmospheric CO2 concentration are considered in detail. The changes in the solar constant are sufficient to change ocean temperatures and alter the Earth’s climate.

Figure 4

The surface temperature changes produced by an increase in downward LWIR flux are too small to be measured and cannot cause climate change. The assumptions underlying the use of radiative forcing in climate models are shown to be invalid. A null hypothesis for CO2 is proposed that it is impossible to show that changes in CO2 concentration have caused any climate change, at least since the current composition of the atmosphere was set by ocean photosynthesis about one billion years ago.
