The BBC loves its so-called ‘greenhouse gases’ and is convinced they control the climate, but forgets that they mostly consist of water vapour and the alleged effects are based on failing climate models. Now it seems the dash for renewable electricity is adding even more of these supposedly fearsome molecules to the poor defenceless atmosphere. Clean, green electricity? Not quite. How will climate miserablists cope with this shocking – to them – news?

It’s the most powerful greenhouse gas you’ve never heard of, and levels in the atmosphere are soaring,wails the BBC.

Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.

But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

Levels are rising as an unintended consequence of the green energy boom.

Somehow this apparently innocuous non-problem has to be hyped up into a crisis of epic proportions. To help achieve this, an army of climate spin doctors is always on hand to attempt the never-ending task of blaming humans for any kind of unpleasant weather.

When American climate alarmists claim to have witnessed the effects of global warming, they must be referring to a time beyond 14 years ago, says James Taylor @ RealClear Energy.

That is because there has been no warming in the United States since at least 2005, according to updated data from the National Oceanic and Atmospheric Administration (NOAA).

In January 2005, NOAA began recording temperatures at its newly built U.S. Climate Reference Network (USCRN). USCRN includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states.

A key finding of this research concerns the Intertropical Convergence Zone (ITCZ). The researchers report ‘southward mean positions of ITCZ during the early Medieval Warm Period and the Current Warm Period in the central Indo-Pacific.’ This seems to contradict claims, repeated recently, that the MWP was confined to northern parts of the European and American continents, or at least was not global. But the ITCZ is a global phenomenon, which in turn suggests any recent warming (CWP) could have similar origins to the MWP – surely a somewhat inconvenient proposition for man-made greenhouse gas theorists. Remember this Climategate story – ‘We have to get rid of the Medieval Warm Period’?

Rainfall variations in the tropics not only potentially influence 40% of the world’s population and the stability of the global ecosystem, but also the global hydrologic cycle and energy balance, says Phys.org.

Beginning in the 20th century, a decline in northern tropical rainfall has been observed, with researchers unsure whether the decline stems from natural or anthropogenic causes.

New rainfall research has shed some light on this question, but left the final answer up in the air.

Photosynthesis: nature requires carbon dioxide


More of the usual propaganda about ‘human-induced climate change’. Not mentioned is the fact that most of their so-called ‘greenhouse gas’ is water vapour, which has little or nothing to do with human activities, and much of the carbon dioxide has always been due to natural factors.

A major report says the West’s high consumption of meat is fuelling global warming, reports the BBC.

But scientists and officials stopped short of explicitly calling on everyone to become vegan or vegetarian.

They said that more people could be fed using less land if individuals cut down on eating meat.

This is a prelude to a new IPCC report. It’s an exercise in mixing problems that do exist, like biofuels using too much land, with ones that don’t, like excess trace gases in the atmosphere. The end product is the usual alarm-and-confusion brand of propaganda for man-made warming believers, with wild talk of meltdowns, deadly extremes and so forth. More like a Hollywood script than anything resembling reality – but over-the-top stuff like this seems to be standard fare in much of the media nowadays.

The overlapping crises of climate change, mass species extinction, and an unsustainable global food system are on a collision course towards what might best be called an ecological land grab, says Phys.org.

Coping with each of these problems will require a different way of using of Earth’s lands, and as experts crunch the numbers it is becoming unnervingly clear that there may not be enough terra firma to go around.

A world of narrowing options threatens to pit biofuels, forests and food production against each other.

A way of getting around some of the questionable data manipulations in vogue at present is proposed. Whether it would appeal to the ‘offenders’, so to speak, is another matter.

July 2019 was probably the 4th warmest of the last 41 years, writes Dr. Roy Spencer.

Global “reanalysis” datasets need to start being used for monitoring of global surface temperatures.

We are now seeing news reports (e.g. CNN, BBC, Reuters) that July 2019 was the hottest month on record for global average surface air temperatures.

One would think that the very best data would be used to make this assessment. After all, it comes from official government sources (such as NOAA, and the World Meteorological Organization [WMO]).

But current official pronouncements of global temperature records come from a fairly limited and error-prone array of thermometers which were never intended to measure global temperature trends.

NOAA’s latest offering on this topic is here. Of course we’re pitched into the world of ‘greenhouse gas’ theory. But it seems to be a world of considerable uncertainty, if the phrases highlighted (by the Talkshop) are anything to go by. Most attention is given to CO2 in the media, but it’s only a very minor player in the atmosphere (0.04%). There’s no accepted figure for ‘water vapor’ (NOAA uses US spelling) as exact data doesn’t exist, although ballpark estimates from various readings can be found. Why do greenhouse gas believers obsess about CO2 when they don’t know a lot about what’s going on with water vapor, which is on the face of it far more important to their theory?

Water Vapor is the most abundant greenhouse gas in the atmosphere, which is why it is addressed here first. However, changes in its concentration is also considered to be a result of climate feedbacks related to the warming of the atmosphere rather than a direct result of industrialization.

The feedback loop in which water is involved is critically important to projecting future climate change, but as yet is still fairly poorly measured and understood.

Whether the urban heat island effect is in fact warming ‘the climate’ is debatable, but in a propaganda war it can be made to seem so. In any case this needs as wide a coverage as possible, to offset at least some of the alarmist spin about supposed man-made warming that’s pushed down everyone’s throat on a daily basis.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

A new study by Nicola Scafetta shows that a considerable percentage of China’s global warming from 1940 to today is due to the phenomenon of urbanization. However, the models mistakenly associated this same warming to anthropogenic forcing:

Near-surface temperature records show that China warmed by about 0.8 °C from 1950 to 2010. However, there exists an ongoing debate about whether this warming might have been partially due to urbanization bias. In fact, homogenization approaches may be inefficient in densely populated provinces that have experienced a significant urban development since the 1940s. This paper aims to complement previous research on the topic by showing that an alternative approach based on the analysis of the divergence between the minimum (Tmin) and maximum (Tmax) near-surface temperature records since the 1940s could be useful to clarify the issue because urban heat island (UHI) effects stress the warming of nocturnal temperatures…

The climate apocalypse bandwagon first got going nearly as long ago as the first moon landing, but shows no signs of falling apart despite a dismal record of no-show of its forecasts, as Climate Change Dispatch explains. The urge to blame humans for any and all vagaries, real or imagined, of the climate seems deep-rooted despite this ongoing lack of predictive success.

This month, The Wall Street Journal celebrated its 130th anniversary by republishing salient articles spanning that period, including this retrospectively illuminating report from February 2, 1978:

A climatic disaster, triggered by the continued burning of oil and coal, could result in the submergence of much of Florida, Holland and other low-lying areas in the next 50 years, an Ohio State University scientist predicted… “I contend that a major disaster – a rapid five-meter rise in sea level caused by deglaciation of West Antarctica – may be imminent or in progress, after atmospheric carbon dioxide has only doubled,” John H. Mercer, a glacier geologist, asserted.

By some miracle, fortunately, Florida and Holland were still with us over a decade later.

Whatever exactly was supposed to have been agreed on, it must be difficult to show 97% support without any actual data to back it up. Is it any more than fake news?

The Competitive Enterprise Institute (CEI) petitioned NASA to remove from its website the claim that 97 percent of climate scientists agree humans are responsible for global warming, reports The Global Warming Policy Forum (GWPF).

The petition, filed under the Information Quality Act (IQA), points out the major flaws in the studies cited by NASA to substantiate its claim. 

It requests the agency remove the claim from its website and stop circulating it in agency materials.

As the energy policies of various countries sink ever further into the realms of fantasy over the imagined role of minor trace gases in the atmosphere, what will the US do – or not do?

The current unilateral US decarbonization proposals by various Democrats promoting the Green New Deal (GND) climate schemes suffer from two particularly crucial assumptions that they have made, says Alan Carlin.

One is the extremely doubtful assumption that CO2 levels determine temperatures as opposed to temperatures determining CO2 levels. The assumption being made is that it is the atmospheric CO2 level that is the critical determinant of temperatures.

If this is wrong, as I believe it is, any dollar spent on decarbonization will provide no benefits in terms of global temperatures.

These UN delegates won’t want to hear about the latest paper from Professor Zharkova et al, which forecasts a natural rise in global temperatures until 2600 that is much higher than the arbitrary 1.5C ‘target’ they think they can buy for themselves, at vast public expense of course, by playing around with the trace gas content of the atmosphere. But, secure in their echo chamber of man-made warming beliefs and the conviction they are somehow able to control the Earth’s climate, the chances are they either won’t hear of the new research or will ignore it anyway.

A “triple whammy” of events threatens to hamper efforts to tackle climate change say UN delegates, says BBC News.

At a meeting in Bonn, Saudi Arabia has continued to object to a key IPCC scientific report that urges drastic cuts in carbon emissions.

Added to that, the EU has so far failed to agree to a long term net zero emissions target.

Thirdly, a draft text from the G20 summit in Japan later this week waters down commitments to tackle warming.

One attendee in Bonn said that, taken together, the moves represented a fierce backlash from countries with strong fossil fuel interests.

Politicians keen to promote climate alarm run the risk of embarrassing themselves when pronouncing on random weather events.

H/T Climate Change Dispatch

With destructive tornadoes comes climate alarmism, so it’s useful to know why so-called global warming would produce fewer – not more – cyclonic events, says Dr Roy Spencer.

Progressive politicians like Al Gore, Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D.-N.Y., don’t hesitate to blame any kind of severe weather – even if it is decreasing over time – on global warming.

With the devastating Dayton, Ohio, tornadoes fresh on our minds, it is useful to examine exactly why (modest) global warming has produced fewer – not more – of such events.

The simple answer is that tornado formation requires unusually cool air.

Unusually cold local weather for this time of year, not conforming to supposed warming trends claimed to be due to too many SUVs, power stations etc. Records may fall.

As of 8 a.m. on Tuesday, Denver had officially received 3.4 inches of snow, says CBS4 News.

That’s the most snow measured this late in the season since May 29, 1975 when 5.6 inches hit the city.

In addition to the snow, Denver tied the record low temperature for May 21 when the official thermometer for the city dropped to 31 degrees Tuesday morning. It was previously 31 degrees on this date in 2001 when 1 inch of snow fell.

In terms of high temperatures on Tuesday, they will struggle to reach into the lower 40s again making it the second day in a row with temperatures staying 30 to 35 degrees below normal for the third week in May.

The record “coldest maximum” for May 21 is 40 degrees set 128 years ago in 1891. It’s possible that record could also be challenged.

Is climate alarm propaganda worse than we thought?

PA Pundits - International

From the team at CFACT ~

Newly published data gathered by NASA’s AIRS satellite confirm the Earth is warming more slowly than has been forecast by climate activists and the United Nations Intergovernmental Panel on Climate Change (IPCC). Data gathered from 2003 through 2017 confirm temperatures remained essentially flat from 2003 through 2015, finally rising briefly as a strong El Nino formed in 2015 and lasted into 2016 (https://ggweather.com/enso/oni.htm). Even with El Nino adding an illusory warming spike at the end of the period, temperatures still rose just over 0.2 degrees during the 15-year period. That pace works out to less than 1.5 degrees of warming per century.

IPCC initial forecasts called for 0.3 degrees Celsius of warming per decade, while skeptic forecasts have tended to hover around 0.1 degrees. As temperatures warmed more slowly than IPCC predicted, IPCC reduced its forecasts to meet skeptics in the middle…

Trevor Kavanagh blasts the ineffective UK government over its Brexit and climate dithering.

H/T Climate Change Dispatch

The Tories are facing extinction, having beaten themselves to a pulp over Brexit, and are too stupefied to defend themselves over false global warming claims.

The Tories are facing extinction – without even the pleasure of a rebellion.

Having beaten themselves to a pulp over Brexit, they are now too punch-drunk to defend themselves over global warming.

Lifelong Swampy Jeremy Corbyn has latched on to climate change as a lethal weapon against a party which has lost control of the agenda. Idealistic young voters are all ears.

There is a solution to our looming energy crisis — cheap, clean shale gas. But feeble Energy Secretary Greg Clark threw it away, forcing fracking tsar Natascha Engel to quit yesterday in disgust.

Stating the obvious, but they’re either going to find a lot of fuel or lose a lot of money. Chances of the demand fading any time soon still look remote, with global consumption at or near 100 million barrels of oil *per day*. Many believers in greenhouse gas theories of course continue to swallow the propaganda that climate disaster lurks around every corner.

Plans by oil and gas majors to spend $4.9 trillion on fuel exploration are “poles apart” from the goal of the Paris climate deal to limit the global temperature rise, a new analysis showed Tuesday.

As greenhouse gas emissions continue to climb annually, a string of warnings from the world’s top climate scientists have questioned mankind’s ability to prevent the worst effects of global warming while sticking with an economy geared around fossil fuels.

In October, the UN’s climate change panel (IPCC) issued a landmark report saying that a 1.5 Celsius target laid out in the Paris accord could only be hit with near-immediate and drastic cuts in production and consumption of oil, gas and coal.

As the forces of climate alarm degenerate ever further into synthetic hysteria and absurdity, Ross McKitrick tries to restore some perspective.

Science Matters

In a legal proceeding, a witness can only testify to what he or she personally experienced. Anything reported to them by others is dismissed as “hearsay”, not evidence by direct observation, but rather an opinion offered by someone else.

In the current public commotion over global warming, almost all the discourse is composed of hearsay.  Ross McKitrick explains that the alleged changes in temperatures are so small that no one can possibly notice. Thus, their concern over global warming can only come from repeating hearsay in the form of charts and graphs published by people with an axe to grind. His article in the Financial Post is Hold the panic: Canada just warmed 1.7 degrees and … thrived. Excerpts below in italics with my bolds.

A recent report, commissioned by Environment and Climate Change Canada (also known as the federal Department of the Environment), sparked a feverish bout of…
