Whether wood is truly renewable or not is a matter of opinion. Trees can be burnt in minutes but regrowth obviously takes many years. Theory has it that new trees can over time recover the carbon dioxide from tree burning but how realistic is that? Not very much, according to experts. The same politicians who attend climate conferences proclaiming ’emissions’ are a terrible problem now actively support making them worse. You couldn’t make it up.

Europe’s decision to promote the use of wood as a “renewable fuel” will likely greatly increase Europe’s greenhouse gas emissions and cause severe harm to the world’s forests, according to a new paper published in Nature Communications.

European officials on final language for a renewable energy directive earlier this summer that will almost double Europe’s use of renewable energy by 2030.

Against the advice of 800 scientists, the directive now treats wood as a low-carbon fuel, reports Phys.org, meaning that whole trees or large portions of trees can be cut down deliberately to burn.

Antarctica


Researchers describe this as ‘a major challenge to our current understanding’. The global carbon cycle model may have to be revisited.

More than 100 oceanic floats are now diving and drifting in the Southern Ocean around Antarctica during the peak of winter, reports Phys.org.

These instruments are gathering data from a place and season that remains very poorly studied, despite its important role in regulating the global climate.

A new study from the University of Washington, the Monterey Bay Aquarium Research Institute, Princeton University and several other oceanographic institutions uses data gathered by the floating drones over past winters to learn how much carbon dioxide is transferred by the surrounding seas.

Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.

An interesting contribution to the ice age debate here. Problems with Milankovitch and CO2-related theories are discussed.

Thongchai Thailand

Gerald Marsh, retired Argonne National Laboratories Physicist, challenges the usual assumption that ice age cycles are initiated by Milankovich Cycles and driven by the Arrhenius effect of carbon dioxide. He says that the key variable here is “low altitude cloud cover” driven by cosmic rays. A paper worth reading.

ABSTRACT

  1. The existing understanding of interglacial periods is that they
    are initiated by Milankovitch cycles enhanced by rising atmospheric
    carbon dioxide concentrations. During interglacials, global temperature is
    also believed to be primarily controlled by carbon dioxide concentrations,
    modulated by internal processes such as the Pacific Decadal Oscillation
    and the North Atlantic Oscillation. Recent work challenges the
    fundamental basis of these conceptions.
  2. INTRODUCTION
    The history of the role of carbon dioxide in climate begins with the work of Tyndall 1861 and later in 1896 by Arrhenius. The concept that carbon dioxide controlled climate fell into disfavor for a variety of reasons until…

New York’s other Battery: Battery Park in Manhattan (image credit: Gryffindor @ Wikipedia)


New York expects to change its future weather by installing lots of expensive mega-batteries, according to the Governor. But is fear of a harmless trace gas essential to life more like superstition than science?

The state has set a target to install 1.5GW of batteries by 2025, reports Energy Live News.

New York Governor Andrew M. Cuomo has announced an ‘Energy Storage Roadmap’ to guide the state toward its energy storage target of 1.5GW by 2025.

Since climate scares were first sponsored by governments, neither the theory of man-made causality nor the evidence for it have improved. Models have failed to predict what actually happened. Time’s almost up for alarmists.

Fool Me Once Shame on You,
Fool Me Twice, Shame on Me.

It was just 30 years ago this week that James Hansen, the former NASA scientist who testified before the Senate Energy and Natural Resources Committee during a prolonged heat wave, which” he described as a climate event of cosmic significance.” Just to be sure he arranged for the meeting room to be warmer than usual. He expressed to the senators “his high degree of confidence” in “cause-and-effect relationship between the greenhouse effect and observed warming.”

There was an accompanying paper in the Journal of Geophysical Research, and it ignited a world wide panic that continues today about the energy structure of the entire planet. So 30 years on we can pause and take a look at just how well his predictions have turned out, and check on how we are doing.

Mr. Hansen’s testimony described three possible…

How much longer can the erroneous fixed ideas of IPCC-based climate science last against the forces (see signatory list) of reason and rationality?

NOT A LOT OF PEOPLE KNOW THAT

GWPF carry the story of a letter recently sent to the president of the Geological Society by a group of concerned current and former members:

The President
Geological Society of London

Dear President

We are writing as a group of concerned primarily geoscientists, half of whom are or were Fellows, (names and affiliations listed below). Our concern is that the Society’s position on Climate Change (aka Anthropogenic Global Warming or AGW), is outdated and one-sided, and is distracting attention and funding from real issues of pollution such as plastic and other noxious industrial and domestic waste. To address this, we proposed to Colin Summerhayes that the 2010 and 2013 GSL Position Papers be posted on the Energy Matters blog, so that all sides of the discussion could be aired; and we are very grateful to Colin for effecting and taking part in this (http://euanmearns.com/the-geological-society-of-londons-statement-on-climate-change/).

The author poses what he calls the ‘major question’: why does CO2 have no significant effect on temperatures in the real world?
(See also this Press Release).

The major development in climate science in the last year or two is something almost no one talks about, says Alan Carlinstrong evidence that changes in atmospheric carbon dioxide levels have no significant effect on global temperatures in the real world over recent decades.

The studies involved conclude that the minor increases in global temperatures during this period can be entirely explained using natural factors.

Warming up for climate negotiations ?

Where have we heard this before? Obviously at every other UN climate meeting that tried to extort vast sums of money from unwilling donor countries, to pay for supposedly climate-related schemes. No wonder the USA walked away from the endless wrangling over a trace gas in the atmosphere.

Old divisions between rich and poor over money and ambition are again threatening to limit progress in UN climate negotiations, says BBC News.

Discussions between negotiators from nearly 200 countries have resumed in Germany, aiming to flesh out the rules on the Paris climate pact.

But developing countries say they are “frustrated” with the lack of leadership from the developed world. Commitments to cut carbon are still “woefully inadequate” they said.

Leaving aside whether ‘climate sensitivity’ (to carbon dioxide) is a valid concept in the first place, it’s been obvious for a while that climate modellers have seriously overestimated the actual level of any warming that has occurred in recent years. If that doesn’t suggest to them that something is wrong, what would?
H/T The GWPF

London, 24 April — A paper just published by the Journal of Climate concludes that high estimates of future global warming from most computer climate simulations are inconsistent with observed warming since 1850. The implication is that future warming will be 30 to 45% lower than suggested by the simulations.

The study estimates climate sensitivity — how much the world will warm when carbon dioxide levels increase* — from changes in observed temperatures and estimates of the warming effect of greenhouse gases and other drivers of climate change, from the mid/late 19th century until 2016.

The paper also addresses previous criticisms of the methodology used, finding that these are unfounded.

The incorrect demonising of carbon dioxide has poisoned the minds of many political leaders. Painful reality is bound to catch up with them and their misguided energy polices sooner or later.

STOP THESE THINGS

It takes a special brand of ignorance to still believe that the world can run on sunshine and breezes. Whether you blame a breakdown in the education system or a Trotskyite takeover of the mainstream media, the results are the same: there’s a stubborn rump who continue to turn fantasy into ‘fact’; who are incapable of distinguishing the former from the latter; and who are by far the most rabid and shrill when it comes to the topic of the generation of electricity.

Our good friends logic and reason were sacrificed on the altar of ideology, a generation ago.

Defending those critical attributes of an ordered and civil society is what STT is all about. Of course, the wind and sun cult hate us for that.

You can’t blame them; when you have a child-like belief in something you deeply love (think Father Christmas, the Easter Bunny, talking unicorns) and…

“These results are going to require rewriting the textbooks,” according to the research program director.

Not all of the nitrogen on the planet comes from the atmosphere, according to a UC Davis study in the journal Science. Up to a quarter comes from Earth’s bedrock. 

The discovery could greatly improve climate change projections, says Eurekalert.

‘The salinity puzzle’ – something new for climate theorists to ponder and debate. Here they still refer to ‘heat-trapping’ gases, having ignored or forgotten about convection.

Researchers aboard an Australian ship undertaking pioneering work in the Southern Ocean have found the “first hint” of a shift in a decades-long trend towards fresher, less dense water off Antarctica, reports The Age.

Teams of scientists on the RV Investigator have been profiling the salinity and temperature of water between Tasmania and Antarctica at 108 locations. They also released the first batch of deep Argot floats to measure conditions as deep as 4000 metres.

But it is the early analysis of data on salinity in the so-called bottom waters near the seabed that may stir international debate.

This isn’t the first time a dust-related theory of long-term climate change has been put forward. But this one looks at what could have caused the Earth to go into cycles of glacial and interglacial periods in the first place.

Dust that blew into the North Pacific Ocean could help explain why the Earth’s climate cooled 2.7 million years ago, according to a new study, reports ScienceDaily.

One of the co-authors was Alex Pullen, an assistant professor of environmental engineering and earth sciences at Clemson University.

“Why study the past? It’s a great predictor of the future,” he said. “The findings of this study were both interesting and very unexpected.”

Shale gas drilling site [image credit: BBC]


Current forecasts say gas will be providing 7 times more energy worldwide than all renewables by 2040. Why import it when it’s in the ground?
H/T The GWPF

Horizontal drilling and hydraulic fracturing are the biggest energy breakthrough of the century, writes Matt Ridley in The Times.

Gas will start flowing from Cuadrilla’s two shale exploration wells in Lancashire this year. Preliminary analysis of the site is “very encouraging”, bearing out the British Geological Survey’s analysis that the Bowland Shale beneath northern England holds one of the richest gas resources known: a huge store of energy at a cost well below that of renewables and nuclear.

Renewable energy has an unwelcome customer: ‘Bitcoin emits the equivalent of 17.7 million tons of carbon dioxide every year’ according to one recent report. Unless or until its bubble bursts, that figure is expected to rise.

KEFLAVIK, Iceland (AP) — Iceland is expected to use more energy “mining” bitcoins and other virtual currencies this year than it uses to power its homes, says AP News.

With massive amounts of electricity needed to run the computers that create bitcoins, large virtual currency companies have established a base in the North Atlantic island nation blessed with an abundance of renewable energy.

The new industry’s relatively sudden growth prompted lawmaker Smari McCarthy of Iceland’s Pirate Party to suggest taxing the profits of bitcoin mines.

The initiative is likely to be well received by Icelanders, who are skeptical of speculative financial ventures after the country’s catastrophic 2008 banking crash.

As the report concludes: ‘Both global warming and carbon dioxide have benefitted plant growth, and both are important contributors to the success of modern civilization.’

Global cereal (grain) production has reached record levels in 2017, says The GWPF.

Credit for the increase usually goes to agrochemicals and other advanced agricultural technology. However, there are two other key contributors — carbon dioxide and climate change.

World cereal production for 2017 is projected to reach 2,613.3 million tons, 5.8 million tons above 2016’s level and nearly one-fourth higher than 2008’s. Despite population growth, production per capita rose 13 percent over the last decade, from 0.31 to 0.35 tons per person.

Gateway to the COP24 climate conference in 2018


Poland doesn’t plan to undermine its economy to please the EU or anyone else with an agenda. The report notes: ‘Ironically, next year’s climate conference will be held in the southern Polish city of Katowice – the centre of the coal-producing Silesia region’. Maybe the local miners would like to pay them a visit 😎

Poland is on a collision course with EU chiefs over its continued heavy use of fossil fuels, as the country prepares to receive its first shipment of US coal, reports the GWPF.

Prime Minister Beata Szydło has warned MEPs she will “throw it back at them” if they criticise her nation’s carbon consumption at next month’s EU summit.

And that could set the scene for more stand-offs next year, when Poland hosts the next round of UN climate talks.

The idea, so heavily pushed these days, that we are on the brink of ‘hot’ times looks more than a bit weak when compared to some earlier epochs on Earth. Regarding raised CO2 levels, the finding that ‘the most likely source of the carbon [dioxide] came from thawing permafrost during the period studied’ strongly suggests that the thaw would be causing the gas release, not the other way round. Phys.org reporting.

Concentration of carbon dioxide during an intense period of global warmth may have been as low as half the level previously suggested by scientists, according to a new Dartmouth College study.

The study found that carbon dioxide may have been less than 1000 parts per million, or ppm, during the Earth’s early Eocene period. This runs counter to thinking that concentration levels were as high as 2000 ppm in the same time frame.

By comparison, current levels of carbon dioxide observed at NOAA’s Mauna Loa Observatory are around 400 ppm.

Earth and climate – an ongoing controversy

A new study by Nicola Scafetta and colleagues is featured at The Global Warming Policy Forum (GWPF).

ABSTRACT The period from 2000 to 2016 shows a modest warming trend that the advocates of the anthropogenic global warming theory have labeled as the “pause” or “hiatus.” These labels were chosen to indicate that the observed temperature standstill period results from an unforced internal fluctuation of the climate (e.g. by heat uptake of the deep ocean) that the computer climate models are claimed to occasionally reproduce without contradicting the anthropogenic global warming theory (AGWT) paradigm.

In part 1 of this work, it was shown that the statistical analysis rejects such labels with a 95% confidence because the standstill period has lasted more than the 15 year period limit provided by the AGWT advocates themselves. Anyhow, the strong warming peak observed in 2015-2016, the “hottest year on record,” gave the impression that the temperature standstill stopped in 2014. Herein, the authors show that such a temperature peak is unrelated to anthropogenic forcing: it simply emerged from the natural fast fluctuations of the climate associated to the El Niño–Southern Oscillation (ENSO) phenomenon.
