Global decarbonisation efforts ‘stall’, pushing climate goals out of reach

by Matt  Mace, Sep. 19, 2019 in Euractiv


Global decarbonisation efforts will need to be seven times greater if the world is to stand a fair chance of limiting global warming to 1.5C, according to a new PwC report which found decarbonisation has slowed to its lowest level since 2011. EURACTIV’s media partner edie.net reports.

PwC UK’s latest Low Carbon Economy Index (LCEI), published today (19 September), found that reaching the Paris Agreement’s 2C limit for global warming would require the global economy to reduce its carbon intensity by 7.5% every year up to 2100. The report notes that this is five times faster than the current decarbonisation rate of 1.6% – less than half the decarbonisation rate witnessed in 2015 (of 3.3%), when the Paris Agreement was introduced.

In order to meet the more ambitious target of the Paris Agreement – limiting global warming to 1.5C which has been requested by the Intergovernmental Panel on Climate Change (IPCC’s) special report – decarbonisation rates must reach 11.3% annually. That is seven times greater than the current rate, which has slowed to its lowest level since 2011.

Rep. Alexandria Ocasio-Cortez recently suggested Miami would disappear in “a few years” due to climate change. The United Nations is convening a “Climate Action Summit” next week. And climate activist Greta Thunberg is on Capitol Hill this week telling lawmakers they must act soon.

But while data from NASA and other top research agencies confirms global temperatures are indeed rising, a newly compiled retrospective indicates the doomsday rhetoric is perhaps more overheated.

The conservative-leaning Competitive Enterprise Institute has put together a lengthy compilation of apocalyptic predictions dating back decades that did not come to pass, timed as Democratic presidential candidates and climate activists refocus attention on the issue.

The dire predictions, often repeated in the media, warned of a variety of impending disasters – famine, drought, an ice age, and even disappearing nations – if the world failed to act on climate change.

An Associated Press headline from 1989 read “Rising seas could obliterate nations: U.N. officials.” The article detailed a U.N. environmental official warning that entire nations would be eliminated if the world failed to reverse warming by 2000.

Then there were the fears that the world would experience a never-ending “cooling trend in the Northern Hemisphere.” That claim came from an “international team of specialists” cited by The New York Times in 1978.

German Climatologist Werner Kirstein Unloads: “IPCC Is To Deceive People”…Calls Michael Mann’s Chart “A Fake”

by P. Gosselin, Sep.17, 2019  in NoTricksZone


German climate scientist Professor Werner Kirstein was interviewed by alternative media outlet NuoViso,  and since the video was released early this month on Youtube, it has been viewed over 130,000, times.

Politics commissioning reports for money

In the interview Professor Kirstein tells moderator Robert Stein that CO2 emissions have no effect on the climate and that “politicians commission climate scientists to produce expert reports for money.”

“Public is being deceived”

Prof. Kirstein talks about the “conscious deception” of the public and how all research projects and publications by “climate scientists” only have the goal of confirming “man-made climate change” and that different scientific views are not welcome.

According to Kirstein, the public is being deceived with the false information and that the aim of politics is to find a way to collect further taxes and to collect levies.

“We currently see this with the climate tax, which is to be introduced soon,” Kirstein says.

Une brève histoire du climat

by Egbert Egberts, 12 septembre 2019, in ScienceClimatEnergie


ATTENTION ! Cet article pourrait permettre d’économiser des milliards d’euros…

Après un été avec des températures au-dessus de 40°C, les prédictions de catastrophes sont allé bon train. “Si on ne fait rien, …” Nos politiques, pressés par une (petite) partie de leur électorat, proposent des mesures à faire pâlir les contribuables impuissants que nous sommes. Pensez aux mille milliards d’euros que veut dépenser la nouvelle présidente de la Commission européenne pour juguler le climat et limiter le réchauffement climatique.

Dans l’ensemble, on traite cette question sans aucun regard en arrière. Comme si le changement climatique était un phénomène nouveau, qui nous est tombé dessus parce qu’on roule en voiture. Cependant, il ne s’agit pas d’un phénomène nouveau et le monde francophone est particulièrement bien placé pour le savoir. Nous possédons un livre fouillé sur l’évolution du climat entre l’an 58 avant Jésus-Christ et 1842 A. D., un véritable trésor ! Pourquoi ? Parce que cela nous donne le recul indispensable pour mieux comprendre ce qui nous arrive aujourd’hui. En 1845, Joseph-Jean-Nicolas Fuster a publié son livre de 503 pages Des changements dans le climat de la France : histoire de ses révolutions météorologiques aux éditions Capelle à Paris.[1] Son livre nous résume ainsi l’évolution du climat pendant presque deux millénaires.

LONG-TERM US DROUGHT AND PRECIPITATION TRENDS

by R. McKitrick & J. Christy, Sep. 14, 2019 in WUWT


Ross McKitrick and John Christy have published a new paper in the Journal of Hydrology.

Abstract : We estimate trends in US regional precipitation on multiple time spans and scales relevant to the detection of changes in climatic regimes. A large literature has shown that trend estimation in hydrological series may be affected by long-term persistence (LTP) and selection of sample length. We show that 2000-year proxy-based reconstructions of the Palmer Modified Drought Index for the US Southeast (SE) and Pacific Coast (PC) regions exhibit LTP and reveal post- 1900 changes to be within the range of longer-term natural fluctuations. We also use a new data base of daily precipitation records for 20 locations (10 PC and 10 SE) extending back in many cases to the 1870s. Over the 1901–2017 interval upward trends in some measures of average and extreme precipitation appear, but they are not consistently significant and in the full records back to 1872 they largely disappear. They also disappear or reverse in the post-1978 portion of the data set, which is inconsistent with them being responses to enhanced greenhouse gas forcing. We conclude that natural variability is likely the dominant driver of historical changes in precipitation and hence drought dynamics in the US SE and PC.

Important news from the world’s top meteorologist

by Larry Kummer, Editor, Sep.14, 2019 in WUWT


Summary: After years of tacit cooperation with climate activists, the first major climate agency may have begun to turn against their misuse of climate science. If so, this would be a big event in the climate debate. As seen in this interview with the head of the WMO. He has much to say that we need to hear.

Scientists are turning against climate activists and their scare tactics.

but the debate is

Greta, Germany & Green Energy

by J. Curry, Sep. 10, 2019 in BigPictureNews


Anyone who still thinks green/renewable energy is the answer is invited to click over to a web page that monitors Germany’s celebrated Energy Transition (English translation here). The most recent six-month update has just been published. Despite a multi-billion-euro price tag, Germany’s attempts to ditch fossil fuels isn’t going well. At all.

Only six of the transition’s 14 goals (43%) appear achievable by 2020. Here are the two absolutely critical data points:

#1 – Germany’s CO2 emissions reduction targets won’t be met.

#2 – Its previously robust electricity grid is now vulnerable and insecure.

The story of Germany’s energy transition boils down to this: Something that used to work well has been deliberately broken, undermined, degraded, and crippled. A ton of money has been spent. To make things worse.

Over at Forbes, Michael Shellenberger discusses how this latest report card is being covered in the German press. In his words:


‘Alarmism Enforcement’ On Hurricanes And Global Warming

by J. Curry, Sep; 9, 2019 in ClimateChangeDispatch


I used to be concerned about ‘consensus enforcement’ on the topic of climate change.  Now I am concerned about ‘alarmism enforcement.’

Ever since Hurricane Katrina in 2005, any hurricane causing catastrophic damage has been seized upon by climate alarmists as evidence of the horrors of global warming.

As if the record-holding hurricanes from the 1920s through the 1950s never happened.

The catastrophic damage to the Bahamas from Hurricane Dorian is no different.  The ‘official’ statement from the alarmist contingent of climate scientists appears to be this article in the Guardian, by Mann and Dessler:

Unfortunately for the alarmists, there are several factors that are getting in the way of the public promotion of the Mann/Dessler narrative:

Alabama-gate:  President Trump’s insistence on defending his erroneous statements about the forecasts for Dorian impacting Alabama.  A good article summarizing all this was co-authored by one of my former students at Georgia Tech, Brandon Miller [link].

After the Alabama National Weather Service office made a statement that Alabama was not at risk from Dorian, NOAA issued a statement defending President Trump  [link].

A WaPo article describes this latest development [link], and the subsequent outrage among scientists and NOAA employees (past and present.

This whole situation is taking the oxygen out of the room in terms of discussions regarding Dorian and global warming.  Gotta wonder if this was the strategy?

WMO Secretary-General Warns Against Climate ‘Doomsters and Extremists’

by  Anthony Watts, Sep. 6, 2019 in WUWT


London, 6 September: The General-Secretary of the World Meteorological Organization (WMO) says that the alarmist narrative on climate change has gone off the rails and criticised the news media for provoking unjustified anxiety.

Speaking to Finland’s financial newspaper Talouselämä (“The Journal”) on 6 September 2019, Petteri Taalas called for cooler heads to prevail, saying that he does not accept arguments of climate alarmists that the end of the world is at hand.

Dr Taalas also spoke of the dangers of green extremism:

“While climate sceptisism has become less of an issue, now we are being challenged from the other side. Climate experts have been attacked by these people and they claim that we should be much more radical. They are doomsters and extremists; they make threats.”

And he called for the media both to challenge experts and allow a broader range of opinions to be heard.

The Gestalt of Heat Waves

by Clyde Spencer, Sep. 6, 2019 in WUWT


Abstract

Tmax and Tmin time-series are examined to look for historical, empirical evidence to support the claim that heat waves will become more frequent, of longer duration, and with higher temperatures than in the past. The two primary parameters examined are the coefficient of variation and the difference between Tmax and Tmin. There have been periods in the past when heat waves were more common. However, for nearly the last 30 years, there has been a reversal of the correlation of increasing CO2 concentration with the Tmax coefficient of variation. The reversal in differences in Tmax and Tmin indicate something notable happened around 1990.

Introduction

There was much in the press this Summer about the ‘global’ heat waves, particularly in France and Greenland. For an example of some of the pronouncements, see here. The predictions are that we should expect to see heat waves that are more frequent and more severe because of Anthropogenic Global Warming, now more commonly called “Climate Change.” The basis for the claim is unvalidated Global Climate Models, which are generally accepted to be running to warm. The simplistic rationale is that as the nights cool less, it takes less heating the next day to reach unusually high temperatures. Unfortunately, were that true, that would lead one to conclude that heat waves should never stop.

If the predictions of worse future heat waves were valid, one might expect to be able to discern a change occurring already, inasmuch as it is commonly accepted that Earth has been warming at least since the beginning of the Industrial Revolution

Historical European Sea Level Records

I have been working on another sea level related essay and in the process stumbled upon a paper published in 1990 by thePermanent Service for Mean Sea Level (PSMSL).  The title is: “On The Availability Of  European Mean Sea Level Data  by P.L. Woodworth, N.E. Spencer and G. Alcock  (1990)”,  The paper is listed on the PSMSL page of “Publications Relevant to the PSMSL and GLOSS” but is not available there.  [ a  .pdf is available here  courtesy of the library at the University of New Brunswick, Canada ].

Recent global heat waves are correlated to an exceptional solar cycle 24

by J. Van Vliet, Sep. 5, 2019 in ScienceClimatEnergie


Belgium and France were recently affected by an extreme heat wave that took place between 24 and 27 July 2019. This heat wave was in many aspects presented as unprecedented and it has therefore unlocked a large scale reaction by many media. After a few days to cool down, the time has come to express a non-emotional and non-political opinion about such a strong heat wave.

Emotional reactions were normal in such circumstances: the temperatures were extreme and even if France and Belgium were much better prepared that for the 2003 heat wave, the present heat wave has led to important suffering for many poor people or people in bad health and without access to air conditioning.

The heat wave unlocked also many political reactions: it was an opportunity to press once more the threatening mantra of United Nations[1] and IPCC that mankind is responsible for this catastrophic warming and is destroying its own and only planet. A whole caste of politicians, countless academics and so-called “experts”, lobbyists, bureaucrats and NGOs claim that it is urgent to take “strong” measures going up to the replacement of democracy by climatist[2] despotism: even children are enlisted in the political arena. These people number in hundreds of thousands and probably more and they communicate loudly and repeatedly at the UN, through IPCC reports and COP events, in the media and in the streets. Does this imply they are right ? Has mankind something to do with these high temperatures ?

Medieval Warmth Was GLOBAL…Confirmed By Over 1,200 Papers At Google Maps

by P. Gosselin, Sep. 3, 2019 in ClimateChangeDispatch


More than 1,200 publications show the Medieval Warm Period (MWP) was global – an embarrassment to global warming alarmists who claimed it was regional.

Global-warming-alarmist scientists like claiming that the well-documented Medieval Warm Period (MWP) was mostly a regional, North Atlantic phenomenon, and was not global, and so we should just move along and stop questioning man-made global warming.

For example, the online Britannica entry on the Medieval Warm Period written by John P. Rafferty writes that it occurred “predominantly in the Northern Hemisphere from Greenland eastward through Europe and parts of Asia.”

Britannica does state that the claim of a global extent is highly controversial, though it really isn’t as we are about to see.

More than 1,200 papers evidence it was global

Indeed the claim that it was global is now backed up by a huge body of scientific studies meticulously compiled by Dr. Sebastian Lüning of Die kalte Sonne and presented at Google Maps here.

Over 170 News Outlets Vow To Spread Climate Hysteria Ahead Of UN Summit

by  J. Syemour, Sep. 2, 2019 in ClimateChangeDispatch


Objectivity and truth-telling are no longer the most “sacred” responsibilities of the news media, at least according to the far-left The Nation magazine. It’s now … climate change.

“We see Covering Climate Now as a fulfillment of journalism’s most sacred responsibilities, which are to inform people and foster constructive debate about common challenges and opportunities,” The Nation wrote on Aug. 28.

The Nation, Columbia Journalism Review (CJR) and The Guardian spearheaded The Covering Climate Now project.

On Aug. 28, they announced that 170 news outlets around the world signed on to the agenda-driven effort. They bragged that biased journalism will be delivered to a combined audience of hundreds of millions of people.

The list included a Who’s Who of liberal U.S. media outlets including Bloomberg, CBS News, PBS NewsHour, Newsweek, “eminent specialist publications” Nature, Scientific American, InsideClimate News, and “distinguished digital publications” HuffPost, Vox, The Intercept, and Slate.

Audiences can expect to be bombarded by climate alarmism the week of Sept. 16-23, since all the participating outlets agreed to focus on climate that week — just ahead of the UN Intergovernmental Panel on Climate Change summit in New York.

Although some aren’t waiting. CBS has already been celebrating the arrival of 16-year-old “climate warrior” Greta Thunberg and promoting her journey by low-emissions yacht while ignoring the fact that people have to fly to NY to retrieve the boat.

Walruses climbing cliffs and falling off them are natural events: 1994 video from Alaska

by Polar Bear Science, Sept. 2, 2019 in WUWT


Posted on September 1, 2019 | Comments Off on Walruses climbing cliffs and falling off them are natural events: 1994 video from Alaska

US Fish and Wildlife officials in 1994 explain walruses falling to their deaths from a cliff at Cape Pierce in the southern Bering Sea (a haulout for adult males during the ice-free season). Explanation? Overcrowding (too many walruses)!

 

Hype from the Netflix/Attenborough ‘climate change is gonna destroy the world’ fearmongers earlier this year notwithstanding – or the media this summer trying to stir up climate change fever – the US Fish and Wildlife Service determined in October 2017 that the Pacific walrus is not being harmed by climate change and is not likely to be harmed within the foreseeable future (USFWS 2017). The IUCN Red List (2015) lists the Pacific walrus as ‘data deficient‘.

Large herds onshore are a sign of population health, not climate change, and walruses have come ashore in the Chukchi Sea during the ice-free season in summer and/or fall for more than 100 years (Crockford 2014; Fischbach et al. 2016; Lowrey 1985). Those are the relevant scientific facts.
