Central Europe’s Huge Gas Depot Risks Being Empty Next Winter

(Bloomberg) — Conflict between Russia and Germany risks leaving one of central Europe’s biggest natural gas depots empty next winter, just as the continent urgently needs to ensure supplies due to the war in Ukraine.

The Haidach underground depot — located in Austria but connected only to the German grid — is unlikely to get filled after Moscow cut supplies to a Gazprom PJSC unit seized by Berlin’s government, according to energy officials in Vienna, who asked not to be identified in exchange for discussing sensitive topics. The depot is equivalent to about a quarter of Austrian storage capacity.

Europeans need to build fuel inventories to keep warm and run their industries next winter. But Russian sanctions on Gazprom Germania GmbH — in retaliation for Berlin seizing the unit earlier this year — are depriving Haidach of crucial supplies needed for energy security should the war in Ukraine disrupt gas transit to the continent.

To make matters worse, Austrian efforts to break the German bottleneck and stash gas at the site is plagued by pipeline constraints. The Alpine country would need to find a way to connect Haidach to the Austrian network and the nation’s grid operator said it’s still studying how it could meet the government’s demand.

“From a technical perspective, a connection between the storage facility and the Penta West pipeline would have to be built,” operator Gas Connect said in emailed response to Bloomberg questions.

Austria’s Penta West is the closest pipeline that could be extended to connect Haidach with the rest of Austria’s 900-kilometer (559-mile) network. Receiving the necessary regulatory and environmental permissions for that could take years, one official said. Even if all approvals were granted, the Penta West pipeline’s capacity is already fully booked by traders fueling west European markets.

A second gas tender being prepared in Vienna, which could be awarded to help fill Haidach with supplies other than Russian, is also facing challenges because there’s no way of verifying where the fuel comes from once it’s been injected into pipelines, a second official said.

The Guardian: Global Warming is GOOD for Rare Coral?

by E. Worall, May 28, 2022 in WUWT

A rare Guardian good news climate change story.

One of UK’s rarest corals set to expand its range as climate change warms seas

Pink sea fan, at risk from bottom-trawling, predicted to spread northwards around coast up to Scotland as sea temperatures rise

Karen McVeigh @karenmcveigh1 Fri 27 May 2022 21.00 AEST

It is one of Britain’s rarest and most threatened species, primarily due to bottom-trawling fishing, but researchers have found that the pink sea fan coral could expand its range in the climate crisis.

A slow-growing coral found in shallow waters from the western Mediterranean to north-west Ireland and south-west England and Wales, the pink sea fan (Eunicella verrucosa) is classified as vulnerable by the International Union for Conservation of Nature.

But a study by researchers from Exeter University found that the species is likely to spread northwards – including further around the British coast as far as Scotland – by 2100 as global temperatures rise.

…

Dr Tom Jenkins, from Exeter University, said: “We built models to predict the current and future habitat of pink sea fans across an area covering the Bay of Biscay, the British Isles and southern Norway.”

Using a global heating model called RCP 8.5, the researchers predicted that by 2100 there would be suitable habitats for pink sea fans north of the current range. Successful colonisation, the study found, would depend on several factors, including dispersal and competition.

Inconvenient truth for globalists: Arctic ice at 30-year high

by A. Moore, May 25, 2022 in Wind

The World Economic Forum and the globalist movement it helps lead have used the “climate crisis” and the COVID-19 pandemic as pretexts for measures to redistribute the wealth of nations.

But this week, as WEF convenes is annual conference in Davos, Switzerland, the Arctic sea ice expanse so far this month is at a 30-year high, according to data from intergovernmental European Organization for the Exploitation of Meteorological Satellites, points out climate-change skeptic Tony Heller.

EUMETSAT, as the organization is known,  was created through an international convention signed by 30 European nations.

The extent of Arctic ice during the warmer months long has been a metric for climate-change alarmists. In 2007, Al Gore began warning the world that scientists were predicting that by 2013, the Arctic would be ice-free during the summer.

Understanding Abrupt Climate Change in the Late Quaternary

by R.S. Bradley & H.F. Diaz, Nov18,  2021 in Eos

Between about 75,000 and 10,000 years ago, there was a series of sudden and dramatic changes in rainfall patterns in tropical regions likely triggered by changes in ocean water circulation. A recent article in Reviews of Geophysics examines the evidence of these “Tropical Hydroclimatic Events” and explores the potential causes. Here, one of the authors explains more about these abrupt climate change events of the past and suggests how it can inform our understanding of potential future climate change.

What are “Tropical Hydroclimatic Events” (THEs)? When and where did they occur?

When we look back at past climate variations in continental regions of the Tropics and sub-Tropics (~30ºN-30ºS), it is abundantly clear that there were times when climate abruptly changed, causing some areas that were formerly wet to become quite dry, and areas that were formerly dry to become much wetter, disrupting plant and animal communities, as well as people living in the region. We call those changes “Tropical Hydroclimatic Events (THEs).” The changes affected vast areas (and lasted for centuries in some cases_ before the climate shifted back to the former conditions. There were at least half a dozen of these THEs between about 10,000 and 75,000 years ago.

Deloitte: Climate change will cost $178T by 2070

by M. Cohn, May 23, 2022 in AccountingToday

Climate change could cost the global economy $178 trillion over the next 50 years, or a 7.6% cut to global gross domestic product in the year 2070 alone, according to estimates from Deloitte.

A report released Monday by the Big Four firm in conjunction with the World Economic Forum’s annual meeting in Davos, Switzerland, also acknowledged the human costs of the climate crisis. If global warming reaches approximately 3 degrees Celsius by that point, the toll on human lives could be significant, disproportionately affecting the most vulnerable and leading to loss of productivity and employment, food and water scarcity, declining health and well-being, and ushering in an overall lower standard of living across the world.

Bringing order to the chaos of sea level projections

by Royal Netherlands Institute for Sea Research, May 18, 2022 in ScienceDaily

In their effort to provide decisionmakers with insight into the consequences of climate change, climate researchers at NIOZ, Deltares and UU are bringing order to the large amount of sea level projections, translating climate models to expected sea level rise. Their new overview study was published in the scientific journal Earth’s Future. “These results offer tools for decision making on the shorter and longer term.”

Aimée Slangen is a climate scientist at NIOZ and co-author of the IPCC climate report. Together with climate adaptation experts Marjolijn Haasnoot and Gundula Winter from Deltares and Utrecht University, both also IPCC authors, Slangen investigated the similarities and differences between the many sea level projections published in recent years.

Eight families of projections

“We found that the set of more than 80 different projections can be reduced to eight ‘families’,” says Slangen. “Within each of the families of projections that we identified, researchers have often used similar data, but they have for instance used different model approaches. As a result, every new publication resulted in different amounts of projected sea level rise, depending on whether the publication focused on the shorter term or the longer term, or depending on the models used to estimate the processes causing a potentially large contribution of accelerated melting of the Antarctic ice sheet.”

These details are interesting for scientists, but make it more difficult for users to maintain overview. Slangen: “This can be an issue when you have to decide as a government what you are going to do to protect your coasts from rising sea levels. Decision makers can’t adjust their policies with every new publication.”

Half a meter rise before the end of the century

The researchers hope to dispel this doubt, as all families paint a similar picture for the first 50 cm of sea level rise. Slangen: “We will see the first half-meter rise before the end of this century, even if we start reducing greenhouse gas emissions on a large scale. For this period, it therefore makes little difference which family you use for sea level projections.”

According to adaptation expert Haasnoot, this therefore means that we can already start adapting to the consequences of sea level rise now. “Those who have to make the climate-proof decisions can already get started. However, it is important to take into account the uncertainty of the future. If you plan cleverly, you make sure that what you are doing now for a half meter sea level rise can be adjusted later for one meter. That will save a lot of money and effort.”

Radiosonde Temps Show Northern Hemisphere, Tropical Warming Has Mostly Paused Since 1998

by K. Richard, May 22, 2022 in NoTricksZone

A new study indicates nearly all the Northern Hemisphere and Tropical warming in the last 40 years occurred by the late 1990s.

CO2 has risen by about 50 ppm since 1998 (367 to 418 ppm).

Interestingly, upper-air measurements of temperature from balloon-borne sensor radiosonde data, shown below in the image from a new study (Madonna et al., 2022), suggest there was more warming from the early 1980s to late 1990s – when CO2 only rose about 25 ppm (341 to 367 ppm) – than there has been this century.

Radiosonde measurements appear to depict mostly flat temperatures trends since 1998 in both the Northern Hemisphere (25°N to 70°N) and tropics (25°S to 25°N).

La Nina is Not Going Away. What Does This Mean for This Summer’s Weather?

by C. Mass, May 16, 2022 in WUWT

It is now clear that La Nina is not going away, and may hang around into next winter.  

Cold water is entrenched over the central and eastern tropical Pacific (the definition of La Nina) and the latest forecast model runs suggest a continuation into fall.

Several of you have asked:   what does this imply for our summer weather?

Let me tell you.

But first, the bottom line:   the summer effects of La Nina are modest, but will push the western side of our region towards cooler than normal conditions.

The Impacts

During La Nina years, sea surface temperatures off the West coast are usually cooler than normal, and those cooling effects spread inland.

To illustrate, here is the sea surface temperate difference from normal for the summer months (May through September) for La Nina years.    Blue colors are cooler than normal.

Global Sea Surface Temperature Records Suggest Only Modest Warming In The 20th And 21st Centuries

by Dieng et al., 2017 in NoTricksZone

According to Dieng et al., 2017, global sea surface temperatures (SST) cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade.

Sea and land surface temperatures, ocean heat content, Earth’s
energy imbalance and net radiative forcing over the recent years.

The NCAR/HadCRUT4 global SST record from buoys and ARGO floats also show only modest warming in the last 3 decades. The natural 2015-’16 Super El Nino event is mostly responsible for the overall increasing rate.

Why IPCC Climate Forecasts Are So Dodgy

by R. Barmy, May 5, 2022 in ClimateChangeDispatch

This is the fourth in a series of articles on the IPCC’s AR6 WG1 report. –CCD ed.

Margaret Thatcher helped create the United Nations Intergovernmental Panel on Climate Change (IPCC) in 1988. As an Oxford-trained chemist, she understood scientific principles and was concerned that we “… do not live at the expense of future generations.”

By 2002, the Iron Lady turned against global warming extremism by stating in her book Statecraft: Strategies for a Changing World, “What is far more apparent is that the usual suspects on the left have been exaggerating the dangers and simplifying solutions in order to press their agenda…” [bold, links added]

Thatcher’s comments of exaggeration and simplification were a prescient critique of the IPCC report Climate Change 2021: The Physical Sciences Basis.

The IPCC uses computer simulations to predict climate dangers and test solutions. An important step in the computer simulation of a real-world physical process is making sure the simulator can replicate the known history of that physical process.

If a computer model can accurately replicate a significant history of a known process, called hindcasting, it lends credibility that the correct equations are being used and will be able to predict future events.

The Global Warming Scare Is Most Certainly Overheated

by Edidorial Board, May 10, 2022 in Issue&Insight

Does anyone wonder where all the global warming destruction is? After all, the media are unrelenting in telling us how much climate change caused by man is affecting us. Yet no existential threat has emerged. There’s something off with the story.

The climate alarmists have based their predictions of doom on computer models that have been projecting global temperature increases, the likes of which, they tell us, are unsustainable. We must cut our carbon dioxide emissions, even if (actually, especially if) it hurts developed world economies.

This is the narrative we’re bombarded with on a daily basis. And it’s wrong.

Those models that have been used to fuel the fright are, without a doubt, unreliable. According to a recent story published in Nature magazine written by a group of climate modelers, “a subset of the newest generation of models are ‘too hot’ and project climate warming in response to carbon dioxide emissions that might be larger than that supported by other evidence.”

The authors, though, are careful to preserve the narrative, warning that “​​whereas unduly hot outcomes might be unlikely, this does not mean that global warming is not a serious threat.” They can’t help themselves.

While the modelers in the Nature article point specifically to problems with “a subset of the newest generation of models,” it’s obvious that the older models are no better. Last fall we covered a ScienceDaily report which noted that some researchers had concluded “a possible flaw in climate models” had been exposed, as the models failed to reproduce an observed event.

“When the history of climate modeling comes to be written in some distant future,” economist Robert L. Bradley Jr. wrote some months ago for the American Institute for Economic Research, “the major story may well be how the easy, computable answer turned out to be the wrong one, resulting in overestimated warming and false scares from the enhanced (man-made) greenhouse effect.”

PERMAFROST AND CLIMATE CHANGE IN ICELAND

by B. Van Vliet-Lanoé & A. Gudmundsson, Feb 2020, in ResearchGate

Permafrost developed from Termination Ia (Bölling interstadial, 14.5 cal ka BP) in Northern Iceland, in answer to deglaciation. Permafrost persisted or even re-extended during the Preboreal cooling events (at 11.2, 10.3 and 9.3 cal ka BP) synchronic with pulsated glacial advances. It disappeared below 1000 masl during the Thermal Optimum (8-5 cal ka BP). The present-day re-extent was controlled with the cooling related with the Little Ice Age and particularily the Maunder solar Minimum. Continuous permafrost is stable above 1000 masl, but is today melting between 900 and 800 masl. Discontinuous permafrost is vanishing today with the recent climate warming (from 1970), especially in palsa bogs, and on valley slopes with thermokarstic mass wasting.

Holocene ice-free strait followed by dynamic Neoglacial fluctuations: Hornsund, Svalbard

by A. Osaka et al., Apr 25, 2022 in TheHolocene

Keywords

Abstract

The recession of the Hornbreen-Hambergbreen glaciers (Hornsund, Svalbard) will lead to the formation of a strait between the Greenland and Barents Seas within a few decades. We provide evidence for the earlier existence of this strait, in the Early–Middle Holocene and presumably since 1.3 ka cal. BP until glacier advance 0.7 ± 0.3 ka or earlier. Radiocarbon dating of mollusc shells from the ground moraines in the Hornbreen forefield indicate the existence of the marine environment at the contemporary glacierized head of Hornsund since 10.9 ka cal. BP or earlier due to glacier retreat. The gap in the radiocarbon dates between 3.9 and 1.3 ka cal. BP and the published results of 10Be exposure dating on Treskelen suggest the strait’s closure after glacier advance in the Neoglacial. Subsequent re-opening occurred around 1.3 ka cal. BP, but according to 10Be dates from Treskelen, the strait has again been closed since ca. 0.7 ± 0.3 ka or earlier. The oldest known surge of Hornbreen occurred around 1900. Analysis of Landsat satellite images, morphometric indicators characterizing the glacier frontal zones and previous studies indicate one surge of Hambergbreen (1957–1968) and five re-advances of Hornbreen in the 20th century (after 1936, between 1958 and 1962, in 1986–1990, 1998–1999, 2011). While the warmer Holocene intervals might be a benchmark for the effects of future climate change, glacier dynamics in post-Little Ice Age climate warming seems to be an analogue of glacier retreats and re-advances in the earlier periods of the Holocene.

Sea Level: Rise and Fall – Slowing Down to Speed U

by Kip Hansen, Mai 3,2022 in WUWT

Yes, I do know that acceleration, technically, means just a change in velocity.  But, in every day English, we use acceleration to mean an increase in velocity – speeding up — and deceleration as a decrease in velocity – slowing down.  I mention acceleration and deceleration because one of the major talking points of IPCC reported findings about sea level rise, the incessant media mantra, is that “Sea Level Rise is Accelerating”.  (here, here, here, here, here and hundreds more here)

Is sea level rising?  Yes, of course it is.  It has been rising since about 1750-1775, coinciding with the end of the Little Ice Age.  This is widely accepted as shown below:

 

How do we know?  The important aspect of sea level is how it affects the land at the edges of the oceans.  The water level there is measure by tide gauges at the ports and harbors of the world.  The levels recorded by tide gauges are of local Relative Sea Level (RSL) – the level at which the sea surface hits the land.  This measurement includes both the actual rise in the sea surface height (think: distance from the center of the Earth) plus any vertical movement (VLM) of the tide gauge itself, either up or down.  In many locations the land mass itself is subsiding (sinking) due to glacial isostatic adjustment (GIA) as the land mass readjusts itself for the melting of the glaciers of the last great  Ice Age and at most tide gauge locations, the structure to which the tide gauge tself is attached, such as a pier or dock or sea wall, is also itself subsiding due to compaction of the soil underneath and the fact that many such locations are built on man-made filled substrate.  To see if sea level is rising, it is only necessary to look at high quality tide gauge records for whom the VLM is known to be relatively constant.  The linearity of these graphs is typical, there are many, many more.

There’s a few things to note at first glance. The ice floe continued to decrease in thickness into November. It’s thickness then started to increase, but is currently still less than 2 meters. Also the snow depth has gradually been increasing, and (apart from some data glitches!) is now ~38 cm. Finally, for the moment at least, the ice surface temperature has been slowly warming since mid February and is now ~-11 °C.

NEW STUDY: “Part Of North Atlantic Is Cooling”…”Natural Fluctuations Have Been Primary Reason”

by P. Gosselin, Apr 30, 2022 in NoTricksZone

New studies on the Atlantic current system assess the threshold between natural fluctuations and a climate change-driven evolution

25 April, 2022/Kiel, Germany. With a new publication in the scientific journal Nature Climate Change, researchers from Kiel once again contribute to the understanding of changes in the Atlantic Meridional Overturning Circulation (AMOC) – also known as the “Gulf Stream System”. It is important both for the global climate as well as for climate events in Europe. The authors focus on the question whether human-induced climate change is already slowing down this oceanic circulation. According to the new study, natural variations are still dominant. Improved observation systems could help detect human influences on the current system at an early stage.

Is the Atlantic Meridional Overturning Circulation (AMOC) slowing down? Is this system of ocean currents, which is so important for our climate, likely to come to a halt in the future? Are the observed variations a natural phenomenon or are they already caused by human-induced climate change? Researchers from various scientific disciplines use a wide range of methods to better understand the gigantic oceanic circulation.

“The AMOC provides Europe with a mild climate and determines seasonal rainfall patterns in many countries around the Atlantic. If it weakens over the long term, this will also affect our weather and climate. Other consequences could be a faster rise in sea levels at some coasts or a reduction in the ocean’s ability to take up carbon dioxide and mitigate climate change”, Professor Dr. Mojib Latif, Head of the Research Unit: Marine Meteorology at GEOMAR Helmholtz Centre for Ocean Research Kiel, explains. “We depend on the AMOC in many ways – but so far, we can only guess how it will develop, and whether and how strongly we humans ourselves will push it towards a tipping point where an unstoppable collapse will take its course.”

Using observational data, statistical analyses and model calculations, a team led by Professor Latif has therefore examined changes in the current system over the past one hundred years in greater detail. The results have now been published in the scientific journal Nature Climate Change. According to the researchers, part of the North Atlantic is cooling – a striking contrast to the majority of ocean regions. All evaluations indicate that since the beginning of the 20th century, natural fluctuations have been the primary reason for this cooling. Nonetheless, the studies indicate that the AMOC has started to slow down in recent decades.
