ESO telescope observes exoplanet where it rains iron

by C. Rotter, March 13, 2020 in WUWT


Researchers using ESO’s Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.

“One could say that this planet gets rainy in the evening, except it rains iron,” says David Ehrenreich, a professor at the University of Geneva in Switzerland. He led a study, published today in the journal Nature, of this exotic exoplanet. Known as WASP-76b, it is located some 640 light-years away in the constellation of Pisces.

This strange phenomenon happens because the ‘iron rain’ planet only ever shows one face, its day side, to its parent star, its cooler night side remaining in perpetual darkness. Like the Moon on its orbit around the Earth, WASP-76b is ‘tidally locked‘: it takes as long to rotate around its axis as it does to go around the star.

Despite Mild Winter, Europe February Mean Temperatures Show No Warming Over Three Decades

by P. Gosselin, March 13, 2020 in NoTricksZone


By Kirye
and Pierre Gosselin

It’s been a particularly mild winter in Europe this year. But that hasn’t changed the long-term trend over the past 30 years.

Now that the February 2020 data have been coming in, we plot the mean February temperatures for some countries in Europe.

Sweden

Three of 5 stations show February mean temperature in Greta Thunberg’s Sweden have had a cooling trend since 1988! The real data will probably make the climate alarmists upset.

Les glaces terrestres, la cryosphère (1/3)

by J.C. Maurin, 13 mars 2020 in ScienceClimatEnergie


On désigne par cryosphère l’ensemble des glaces terrestres. Son évolution, lors des dernières décennies, est souvent présentée comme préoccupante: il en résulterait une forte hausse des niveaux marins et un changement d’albédo et donc du bilan énergétique de la Terre. Cette première partie de l’article présentera quelques ordres de grandeurs pour les glaces terrestres.
On utilisera principalement les données du chapitre 4 du rapport AR5 WG1 (5th Assessment Report, Working Group 1) qui a été publié en 2013 par l’organisme intergouvernemental GIEC.

 

 

 

 

4. Conclusions

  • La cryosphère c’est en premier lieu les zones proches du pôle Sud : banquises et glaciers ne représentent ensemble que 0,7% du volume de la cryosphère alors que la seule partie Est de l’Antarctique, bien moins connue, représente plus de 75% de la cryosphère, soit 107 fois plus.
  • La simple correction du volume de glace en Antarctique, entre les rapports du GIEC AR4 (2007) et AR5 (2013), est 4 fois plus grande que le volume (Banquises + Glaciers).
  • Les variations actuelles de la cryosphère restent négligeables si on les compare à celles du passé : l’ensemble des glaces terrestres, il y a 20 millénaires, devait avoir un volume au moins double du volume actuel. En effet, la fonte des glaces (entre -18 ka et -8 ka) fait monter le niveau des océans de ≈ 120 m  contre 66 m SLE (Sea Level Equivalent à la Figure 1).

La deuxième partie de l’article (2/3) commentera les choix rédactionnels du GIEC pour le chapitre 4 de l’AR5 et donnera des ordres de grandeurs complémentaires pour les banquises et les glaciers.

Delingpole: Wikipedia Airbrushes List of Climate Sceptic Scientists Out of History

by J. Delingpole, March 9, 2020 in WUWT


Wikipedia has deleted its ‘List of Scientists Who Disagree with the Scientific Consensus on Global Warming’.

Stalin — who set the template for airbrushing inconvenient people out of history — would no doubt have heartily approved of this wanton act of censorship.

But what would probably have pleased him more is the magnificently twisted justification offered by the editor responsible.

Met Office Does Not Know What “Extreme Weather” Is.

by P. Homewood, March 9, 2020 in NotaLotofPeopleKnowThat


https://www.metoffice.gov.uk/about-us/press-office/news/weather-and-climate/2019/weather-overview-2019

According to the Met Office, 2019 was a year of weather extremes in the UK. There is actually very little evidence to back this claim up, but this does not stop them ludicrously claiming one mild day in February as “extreme”!

To most people, extreme weather would be the sort of stuff our ancestors experienced in this very week in 1891:

Russia Just Told the World, “No.”

by Tom Luongo, March 6, 2020 in GoldGoats’NGuns


There is real power in the word “No.”

In fact, I’d argue that it is the single most powerful word in any language.

In the midst of the worst market meltdown in a dozen years which has at its source problems within global dollar-funding markets, Russia found itself in the position to exercise the Power of No.

Multiple overlapping crises are happening worldwide right now and they all interlock into a fabric of chaos.

Between political instability in Europe, presidential primary shenanigans in the U.S., coronavirus creating mass hysteria and Turkey’s military adventurism in Syria, the eastern Mediterranean and Libya, markets are finally calling the bluff of central bankers who have been propping up asset prices for years.

But, at its core, the current crisis stems from the simple truth that those prices around the world are vastly overvalued.

Western government and central bank policies have used the power of the dollar to push the world to this state.

And that state is, at best, meta-stable.

But when this number of shits get this freaking real, well… meeting the fan was inevitable.

And all it took to push a correction into a full-scale panic was the Russians saying, “No.”

The reality has been evident in the commodity markets for months.  Copper and other industrial metals have all been in slumps while equity markets zoomed higher.

But it was oil that was the most confounding of all.

Most of 2019 we saw oil prices behaving oddly as events occurred with regularity to push prices higher but ultimately see them fall.

Since peaking after the killing of Iranian General Qassem Soleimani oil prices have been a one-way trade. Down.

Guerre du prix du pétrole : revanche de la technologie sur l’OPEP

by Samuel Furfari, 9 mars 2020 in Contrepoints


Le monde regorge de pétrole grâce au développement de la technologie. C’est elle qui est le vecteur de la marche du monde de l’énergie.

Je vous avoue que je ne suis pas le cours du pétrole tous les jours. Cela n’a d’importance que pour les traders et les spéculateurs qui engrangent des bénéfices plantureux en jouant sur quelques centimes de volumes gigantesques.

Si vous voulez comprendre la géopolitique du pétrole et donc de l’énergie , il faut observer les tendances lourdes, comme celle du week-end dernier.

Lorsque j’ai publié en mars 2014 un livre intitulé Vive les énergies fossiles qui indique qu’il n’y a aucune raison objective ou technologique pour que le prix du brut dépasse les 100 dollars le baril, on m’a pris pour un farfelu. Même si j’étais probablement le seul à oser le dire ouvertement en milieu francophone, nombreux étaient ceux qui l’affirmaient de vive voix et par écrit dans le monde. Les faits nous ont donné raison.

LA DEMANDE DE PÉTROLE EN CHUTE LIBRE

Face à la chute brusque de l’activité économique occasionnée par l’épidémie de coronavirus, la demande de pétrole est en chute libre. La consommation chinoise de pétrole a chuté de plus de 3 millions de barils par jour.

De toute évidence, cette crise sera bien plus profonde pour l’économie mondiale que celle déclenchée par les subprimes en 2008. On s’attend à un net recul de la demande en énergie primaire et singulièrement du pétrole.

Cela va de soi : les avions qui ne volent pas, les voitures qui restent au garage, les restaurants désertés, les stades fermés, les vacances annulées font dégringoler la consommation de produits pétroliers et partant, de toute l’économie. De quoi réjouir les écologistes profonds !

Vendredi dernier à Vienne, à la réunion de l’OPEP, comme d’habitude la Russie – non membre – a été conviée à participer aux travaux. L’OPEP, qui manipule le prix du brut depuis 1973 voulait réduire sa production pour maintenir le prix au niveau précédant l’arrivée sur scène du virus dévastateur. Par la même occasion Ryad aurait mis l’Iran encore plus à genoux pour le peu de pétrole que celui-ci parvient à écouler au marché noir (l’Iran ne sait plus où stocker le pétrole pompé qu’il ne peut pas vendre).

LES ORIGINES DE LA CHUTE DU PRIX DU PÉTROLE BRUT

Il est vrai que depuis trois ans, l’OPEP et la Russie se sont accordés pour ajuster leurs extractions à la demande mondiale. Il y a bien eu une tentative de faire chuter le prix de manière à restreindre le développement du pétrole de roche-mère des USA, mais en vain.

Cette fois, Moscou n’a pas voulu suivre le leader de l’OPEP – Ryad – et a refusé d’adhérer à la réduction de la production pour soutenir le prix. L’Arabie Saoudite, piquée au vif, a réagi de manière inverse et a déclaré son intention de porter sa production de brut à plus de 10 millions de barils par jour en avril, après l’expiration de l’accord actuel entre l’OPEP et la Russie fin mars – connu sous le nom d’OPEP+.

De plus, elle a réduit le prix de tous ses bruts vers toutes les destinations de 6 à 8 dollars le baril. La conséquence ne s’est pas fait attendre : le prix du brut a chuté à environ 32 dollars le baril.

Les contrats à terme sur le pétrole ont subi leur plus grosse perte quotidienne depuis 1991 lors de la guerre du Golfe. Lors de la crise asiatique de 1998, le Financial Times du 10 septembre 1998 titrait que la seule chose qui était plus basse que le cours du pétrole était le moral de l’économie. On pourrait dire la même chose aujourd’hui.

‘HO! FOR THE POLE!’ — DID DUTCH SHIPS REACH THE 89TH LATITUDE IN 1665 AND 1675?

by H. Hardrada, March 8, 2020 in Electroverse


I [Harry Hardrada] recently unearthed an intriguing piece of literature from a 19th century periodical named ‘Ho! For the Pole!’ in Littell’s Living Age, Volume 66 (1860).

The paper highlights various voyages to the North Pole throughout the 17th-18th centuries with meticulous detail. It appears, according to the article, that many wooden ships penetrated as far north as the 89th latitude in ‘open iceless seas’ during this time — as in 1665 and 1675.

A bit far-fetched?

Perhaps, on the face of it… but there is some good evidence out there which may suggest otherwise.

Arctic Meltdown Latest

by P. Homewood, March 3, 2020 in NotaLotofPeopleKnowThat


Arctic sea ice extent continues to run well ahead of the last few years, as it has done for most of this year so far, and continues to grow at a time of year when it normally begins to stabilise and recede.

Average extent in February was the highest since 2013, and stands greater than 2005 and 2006:

New Study Asserts Cloud Cover Changes Drove The Post-1980s Solar Radiation Increase Important To Recent Warming

by K. Richard, March 2, 2020 in NoTricksZone


Using NASA’s MERRA-2 radiation data, scientists find shortwave radiation (SW) has been rising since the 1980s. The SW increase has been larger and faster than longwave radiation (LW) changes during this same timespan. Cloud variability has been the “main driver” of these trends.

In a new Nature journal paper (Delgado-Bonal et al, 2020) published in Scientific Reports, scientists use radiation records from NASA to conclude shortwave (SW) changes are “mainly determined” by cloud modulation.

Clouds are “showing a declining trend” from 1984-2014. Fewer clouds means less SW radiation is reflected to space and more is absorbed by the Earth’s surface.

ANTARCTIC BLAST DELIVERS RARE SUMMER SNOW AND FREEZING TEMPERATURES TO PARTS OF AUSTRALIA

by Cap Allon, March 2, 2020 in Electroverse


Australia’s “Grand Solar Minimum” summer –which brought record cold/heat, drought/floods, fires, and dust storms– had one final sting in the tail: another flurry of rare summer snow.

While summer down-under officially ended on Saturday, Feb 29, another blast of heavy, unexpected snow began burying parts of Tasmania on Wednesday, Feb 26.

Mountainous areas of the isolated island state reported large accumulations to close out the week, with local meteorologists warning yet more snow could settle above 1,000 m (3,280 ft) –including at Mount Field and Wellington– over the coming days.

 

 

Why are polar bears going extinct? (Spoiler: They’re not)

by S. Crockford, February 24, 2020 in WUWT


Google says many people ask this question so here is the correct answer: polar bears are not going extinct. If you have been told that, you have misunderstood or have been misinformed. Polar bears are well-distributed across their available habitat and population numbers are high (officially 22,000-31,000 at 2015 but likely closer to 26,000-58,000 at 2018): these are features of a healthy, thriving species. ‘Why are polar bears going extinct?’ contains a false premise – there is no need to ask ‘why’ when the ‘polar bears [are] going extinct’ part is not true.1

mother-with-cubs-russia_shutterstock_71694292_web-size-e1582489285608

It is true that in 2007, it was predicted that polar bear numbers would plummet when summer sea ice declined to 42% of 1979 levels for 8 out of 10 years (anticipated to occur by 2050) and extinct or nearly so by 2100 (Amstrup et al. 2007). However, summer sea ice has been at ‘mid-century-like’ levels since 2007 (with year to year variation, see NOAA ice chart below) yet polar bear numbers have increased since 2005. The anticipated disaster did not occur but many people still believe it did because the media and some researchers still give that impression.

The Death Of Science Is The Real Climate Emergency

by M. Phillips, February 25, 2020 in ClimateChangeDispatch


A few commentators have begun to stumble towards the fact that the policy of becoming “carbon neutral” by 2050, as adopted by the UK and the EU, would undo modernity itself.

On Unherd, Peter Franklin observes that, if carried through, the policy will have a far greater effect than Brexit or anything else; it will transform society altogether.

“It will continue to transform the power industry, and much else besides: every mode of transport; how we build, warm and cool our homes; food, agriculture and land use; trade, industry, every part of the economy”.

Franklin is correct. Even so, he seems not to grasp the full implications of the disaster he intuits – because he thinks there’s some kind of middle way through which the imminent eco-apocalypse can be prevented without returning Britain to the Middle Ages.

In a similar vein, he quotes Rachel Wolf, a co-author of the 2019 Conservative manifesto, who is prone to the same kind of magical thinking. She wrote:

“Government has committed to ‘net zero’ greenhouse gas emissions because it does not want the side effects of the energy sources we have used for centuries to destroy the planet. At the same time, we do not want to return to an era where children (and their mothers) regularly died, and where the majority of people lived in what would now in the UK be considered wholly unacceptable poverty. This is a staggering challenge.”

This is what we might call an understatement. What is truly staggering is, first, that any sentient person thinks this can be done and, second, that it should be done.

New Study: Greenland’s Largest Glacier Has Rapidly Thickened Since 2016…Fueled By 1.5°C Regional Ocean Cooling

by K. Richard, February 17, 2020 in NoTricksZone


Greenland’s largest glacier (Jakobshavn) has quite abruptly thickened since 2016. The thickening has been so profound the ice elevations are nearly back to 2010-2011 levels. The nearby ocean has cooled ~1.5°C – a return to 1980s-era temperatures.

The world’s glaciers have not been following along with the CO2-driven catastrophic melting narrative.

Alaska

For example, in a study of 50 Alaskan glaciers for the warming period between 1972-2012, researchers (McNabb and Hock, 2014) found there was
“…no corresponding change in the number of glaciers retreating nor do we see corresponding acceleration of retreat rates. To the contrary, many glaciers in the region have advanced…”

Jan 2020: Coldest ever day in Greenland -65C comes, goes, no one notices

by JoNova, February 2020


The coldest ever day recorded in Greenland stands at -63.3 C  (minus 81 F).  But on January 2nd in 2020, after Greenland suffered a century of global warming, the thermometer at Summit Camp sunk to at least -64.9C. I say, at least, because it may have been even colder. Sharp eyes of Cap Allon at Electroverse saw it hit minus 66C. Ryan Maue also saw it and predicted there would be cold as the Arctic Oscillation broke down.

I sought confirmation at the time (among the Bushfire days in Australia). I looked for any official tweet even, but couldn’t find any. How’s that work — a new all time record for a whole continent for any month of the year, and no one who was paid to care about these things even writes a paragraph?

Good for Paul Homewood, who wrote to the DMI (Danish Met Institute) and has now confirmed that the NOAA GeoSummit  records showed it got down to -64.9 C, an all time record.

Do We Really Have Only 12 Years to Live?

by Andy May, February 23, 2020 in WUWT


Why have uninformed celebrities and politicians been telling everyone, who will listen, we are all going to die in a climate catastrophe in 10 to 30 years? U.N. General Assembly President María Fernanda Espinosa Garcés of Ecuador warned us…

 

However, these absurd statements are not supported by even the most fanatical climate alarmists, like Kate Marvel (NASA), Gavin Schmidt (NASA), Katharine Hayhoe (Texas Tech), or Andrea Dutton (University of Florida) (link). The original inspiration for these statements came from a 2018 IPCC report entitled Global Warming of 1.5°C. Even the alarmist Scientific American does not think the world is ending in twelve years.

We will discuss this IPCC report below, but first let’s look at some critical evidence that is not in the report. As usual the IPCC dodges the current benefits of warming and additional CO2, so we need to fill in this gap.

A little over two years ago I posted an essay entitled “Calculating the Cost of Global Warming,” it did not calculate a cost, but discussed calculations made by others. Global warming and the increasing concentration of CO2 in the atmosphere are not existential threats to mankind or to nature. Global warming will not go “runaway,” this idea, discussed here, has been discredited by climate change skeptics and by climate alarmists alike (see here and here for examples). So, given that global warming and additional CO2 will not harm us, we are reduced to a discussion of the economic impacts and benefits, both positive and negative, of global warming and additional CO2.

Unexpected ice

by N. Vizcarra, February 2020 in EarthData/NASA


Paul Holland, a climate modeler with the British Antarctic Survey, has spent the last ten years studying Antarctica’s sea ice and the Southern Ocean. Lately, he has been scrutinizing the seasons of Antarctica and how fast the ice comes and goes. Holland thinks these seasons may be a key to a conundrum: If Earth’s temperatures are getting warmer and sea ice in the Arctic has been shrinking fast, why then is sea ice in the Antarctic slowly increasing?

Spring surprise

Holland used data from NASA’s National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) to calculate the ice concentration rate of growth for each single day, which he called intensification; and the total ice area rate of growth, which he called expansion. “I did that for all thirty years of data and plotted the trends,” he said. Holland’s plots showed that the different regions in the Southern Ocean contributed to the overall increase, but they had very diverse trends in sea ice growth. This suggested that geography and different wind patterns played a role. So to gain more insight Holland looked at seasonal wind trends for the different regions.

Holland found that winds were spreading sea ice out in some regions and compressing or keeping it intact in others and that these effects began in the spring. It contradicted a previous study in which, using ice drift data, Holland and Ron Kwok from the NASA’s Jet Propulsion Laboratory (JPL) found that increasing northward winds during the autumn caused the variations.

“I always thought, and as far as I can tell everyone else thought, that the biggest changes must be in autumn,” Holland said. “But the big result for me now is we need to look at spring. The trend is bigger in the autumn, but it seems to be created in spring.”

“Paul has created two more sea ice metrics that we can use to assess how Antarctic sea ice is responding,” said researcher Sharon Stammerjohn, referring to the measures of intensification and expansion. The new metrics help assess how the system is responding as opposed to simply monitoring the state of the system. “Say your temperature is at 99.2 degrees Fahrenheit,” Stammerjohn said. “You don’t have any insight to that temperature unless you take it again an hour later and you see that it changed to 101 degrees. Then you can say, okay, my system is responding to something.”

Study: Large Part Of 20th-Century Warming Caused By CFCs

by Prof. F. Vahrenholtz, February 20, 2020 in ClimateChaneDispatch


A few days ago, an international research group from the USA, Canada, and Switzerland led by Lorenzo Polvani of Columbia University (New York) published a sensational study in Nature climate change, which attributes a large part of the warming of the 20th century to CFCs (“Substantial twentieth-century Arctic warming caused by ozone-depleting substances“).

Using ten climate models, the researchers calculated the global and Arctic temperature development, once with CFCs (chlorofluorocarbons) in the atmosphere and once without.

According to these models, from 1955 to 2005, global temperatures increase by 0.59°C with CFCs and by 0.39°C without CFCs. One-third of the warming is therefore not caused by CO2 but by the CFCs.

If the remaining warming for CO2 is converted over the five decades, average warming of 0.08°C per decade remains. Not exactly a lot. CFCs have a 19,000-23,000 times stronger forcing than CO2.

Half of Arctic warming due to CFCs

RETOUR SUR 2019

by Samuel Furfari, 21 février 2020, in ScienceClimatEnergie


L’année 2019 aurait été celle de l’hystérie climatique. Les manifestations des jeunes qui ont suivi avec enthousiasme les conseils d’une jeune suédoise ont donné à des politiciens en quête de raison d’être une opportunité pour montrer qu’ils s’occupent de la jeunesse, mais aussi de l’environnement ou plus précisément de « sauver la Planète ».
Qui n’est pas en faveur de la protection de l’environnement ?
Qui n’est pas attentif à la santé ?
L’occasion rêvée pour redonner du sens à la politique était trop belle, d’autant plus qu’il y avait en 2019 l’élection d’un nouveau parlement européen. L’inflation de promesses inconsidérées ne s’est pas fait attendre. Elle a abouti le 11 décembre 2019 à la publication d’une nouvelle stratégie de la Commission européenne appelée « Green Deal » et à son adoption par le Conseil européen le 13 décembre, avec un parlement européen qui en veut encore plus.

L’inflation des promesses est à son comble, tout comme le budget qu’il va falloir débourser pour atteindre ces promesses, destinées en fait à redonner une raison d’être à une Union européenne en manque de projets enthousiasmants pour ses citoyens et ignorée par les pays qui dirigent  les grands enjeux géopolitiques comme l’a manifestement montré le camouflet infligé à Angel Merkel lors de la conférence sur la Libye à  Berlin le 21 janvier 2020 .

Pourtant, sur le front de l’énergie, et non des politiques énergétiques, le début de la révolution annoncée n’a même pas commencé. Au contraire, la toute-puissance des énergies fossiles a été confirmée voire renforcée. La nouvelle géopolitique de l’énergie, qui a été créée grâce à l’abondance des énergies fossiles, s’est affermie et est entérinée par une grande partie du business de l’ énergie.

Britain’s Floods Have Nothing To Do With Climate Chang

by J. Delingpole, February 19, 2020 in ClimateChangeDispatch


Boris Johnson’s Greenest Government Evah has come up with a brilliant new excuse to duck its responsibilities for all the floods now swamping parts of Britain: climate change ate our homework.

From Hereford to Shrewsbury and South Wales to North Yorkshire, swathes of Britain are underwater thanks to flooding in the aftermath of Storm Dennis, which so far has claimed five lives.

There are currently more than 400 flood warnings around Britain, with more heavy rain forecast to come.

But the government has effectively absolved itself of responsibility by pinning the blame on ‘climate change.’

Environment Secretary George ‘Useless’ Eustice has said in an interview with LBC radio that the scale of the flooding is due to the ‘nature of climate change.’

Sir James Bevan, the chief executive of the Environment Agency, has gone a step further by blaming ‘the climate emergency.’

None of this is true. There is no evidence whatsoever to suggest that these floods are anything other than an entirely normal, cyclical event which has been repeated many times over many centuries — with or without the contribution of anthropogenic CO2.

The UN’s Planet Saving Delusion

by Donna Laframboise, February 19, 2020 in BigPictureNews


The UN couldn’t help Haiti recover from an earthquake. But it imagines we’d all perish without it.

UNESCO is supposed to be about cultural preservation. Toward the end of last year, its in-house magazine nevertheless published a special issue on climate change. The official editorial employs the usual cliches. Catastrophic consequences. The “greatest global challenge of our times.” Blah, blah.

Hilariously, this editorial implies that, without a UN plan, the planet simply won’t survive. Earth to UNESCO: could we spend five minutes talking about how the UN has failed – tragically and comprehensively – to save Haiti?

That nation has less than 12 million people. It’s slightly smaller than the US state of Maryland. Because it comprises half of an island, its borders are well-defined. The UN has had a significant presence there since 2004, yet Haiti remains a basket case.

After a devastating earthquake struck in 2010, rebuilding was a huge job at which the UN was spectacularly inept. But that isn’t the half of it. UN peacekeepers then infected the already traumatized local population with cholera.

The peacekeepers were from Nepal, which had just experienced a cholera outbreak. The UN took no steps to ensure its personnel weren’t carrying the disease. Nor did it establish proper sanitation at their encampment. Untreated sewage got dumped into the country’s most important river, contaminating water that was used for drinking, cooking, and bathing.

Plausible scenarios for climate change: 2020-2050

by Judith Curry, February 13, 2020 in WUWT


A range of scenarios for global mean surface temperature change between 2020 and 2050, derived using a semi-empirical approach. All three modes of natural climate variability – volcanoes, solar and internal variability – are expected to act in the direction of cooling during this period.

In the midst of all the angst about 1.5oC or 2.0oC warming or more, as defined relative to some mythical time when climate was alleged to be ‘stable’ and (relatively) uninfluenced by humans, we lose sight of the fact that we have a better baseline period – now. One advantage of using ‘now’ as a baseline for future climate change is that we have good observations to describe  the climate of  ‘now’.

While most of the focus of climate projections is on 2100, the period circa 2020-2050 is of particular importance for several reasons:

  1. It is the period for meeting UNFCCC targets for emissions reductions

  2. Many financial and infrastructure decisions will be made on this time scale

  3. The actual evolution of the climate over this period will influence 1) and 2) above; ‘surprises’ could have adverse impacts on decisions related to 1) and 2).

Physics Professor: CO2’s 0.5°C Impact After Rising To 700 ppm Is So Negligible It’s ‘Effectively Unmeasurable’

by P. Stallinga, February 13, 2020 in NoTricksZone


Dr. Peter Stallinga has published a comprehensive analysis of the Earth’s greenhouse effect. He finds an inconsequential role for CO2.

Doubling CO2 from 350 to 700 ppm yields a warming of less than 0.5°C (500 mK).

Feedbacks to warming are likely negative, as adding CO2 may only serve to speed up natural return-to-equilibrium processes.

As for absorption-reemission perturbation from CO2, “there is nothing CO2 would add to the current heat balance in the atmosphere.”

A portion of Dr. Stallinga’s paper worth highlighting – which he mentions only in passing – refers to the early history of the Earth’s greenhouse effect paradigm.

K. Ångström receives little attention as a pioneer of the conceptualization that warming and cooling resul from radiative imbalances within a planetary greenhouse effect.

About 120 years ago, Ångström (1900) contradicted the oft-cited Arrhenius (1896) – the atmospheric physicist referred to by proponents of anthropogenic global warming.

Ångström suggested Earth’s greenhouse effect is already saturated in its current (1900) state, and therefore increasing CO2 will have “no effect whatsoever” on climate (Stallinga, 2020).

Ångström’s conclusions were largely ignored.

Climatologie actuelle, un (petit) pas vers plus de réalisme ?
