The Shameful Politicization Of Hurricanes

by H.S. Burnett, September 26, 2018 in ClimateChangeDispatch

…

Here are several facts that dispel these myths.

First, although the Atlantic hurricane season is not over yet, thus far, the number of hurricanes occurring this year is below average.

During a typical six-month Atlantic hurricane season, 12 named storms form, six become hurricanes, and three of those become major hurricanes – meaning Category 3 or higher.

This season, 10 named storms have formed in the Atlantic Basin, three of which became hurricanes.

Two other hurricanes briefly became minor storms off the west coast of Africa – and only Florence became a major hurricane.

Furthermore, only one has made landfall in the United States: Florence.

Before the above-average Atlantic hurricane season of 2017, the United States experienced the longest period in recorded history, nine years, without a major hurricane (Category 3 or higher) striking the country.

The Great Global Warming Hoax?

by The Middlelbury Community Network, September 2018

Editor’s Introductory Note: Our planet has been slowly warming since last emerging from the “Little Ice Age” of the 17th century, often associated with the Maunder Minimum.  Before that came the “Medieval Warm Period“, in which temperatures were about the same as they are today.  Both of these climate phenomena are known to have occurred in the Northern Hemisphere, but several hundred years prior to the present, the majority of the Southern Hemisphere was primarily populated by indigenous peoples, where science and scientific observation was limited to non-existent.  Thus we can not say that these periods were necessarily “global”.

However, “Global Warming” in recent historical times has been an undisputable fact, and no one can reasonably deny that.

….

Summary – Exactly what have we learned here?

1.  The “Greenhouse Effect” is a natural and valuable phenomenon, without which, the planet would be uninhabitable.2.  Modest Global Warming, at least up until 1998 when a cooling trend began, has been real.

3.  CO2 is not a significant greenhouse gas; 95% of the contribution is due to Water Vapor.

4.  Man’s contribution to Greenhouse Gasses is relatively insignificant.  We didn’t cause the recent Global Warming and we cannot stop it.

5.  Solar Activity appears to be the principal driver for Climate Change, accompanied by complex ocean currents which distribute the heat and control local weather systems.

6.  CO2 is a useful trace gas in the atmosphere, and the planet would actually benefit by having more, not less of it, because it is not a driver for Global Warming and would enrich our vegetation, yielding better crops to feed the expanding population.

7.  CO2 is not causing global warming, in fact, CO2 is lagging temperature change in all reliable datasets.  The cart is not pulling the donkey, and the future cannot influence the past.

8.  Nothing happening in the climate today is particularly unusual, and in fact has happened many times in the past and will likely happen again in the future.

9.  The UN IPCC has corrupted the “reporting process” so badly, it makes the oil-for-food scandal look like someone stole some kid’s lunch money.  They do not follow the Scientific Method, and modify the science as needed to fit their predetermined conclusions.  In empirical science, one does NOT write the conclusion first, then solicit “opinion” on the report, ignoring any opinion which does not fit their predetermined conclusion while falsifying data to support unrealistic models.

10.  Polar Bear populations are not endangered, in fact current populations are healthy and at almost historic highs.  The push to list them as endangered is an effort to gain political control of their habitat… particularly the North Slope oil fields.

11.  There is no demonstrated causal relationship between hurricanes and/or tornadoes and global warming.  This is sheer conjecture totally unsupported by any material science.

12.  Observed glacial retreats in certain select areas have been going on for hundreds of years, and show no serious correlation to short-term swings in global temperatures.

13.  Greenland is shown to be an island completely surrounded by water, not ice, in maps dating to the 14th century.  There is active geothermal activity in the currently “melting” sections of Greenland.

14.  The Antarctic Ice cover is currently the largest ever observed by satellite, and periodic ice shelf breakups are normal and correlate well with localized tectonic and geothermal activity along the Antarctic Peninsula.

15.  The Global Warming Panic was triggered by an artifact of poor mathematics which has been thoroughly disproved.  The panic is being deliberately nurtured by those who stand to gain both financially and politically from perpetuation of the hoax.

16.  Scientists who “deny” the hoax are often threatened with loss of funding or even their jobs.

17.  The correlation between solar activity and climate is now so strong that solar physicists are now seriously discussing the much greater danger of  pending global cooling.

18.  Biofuel hysteria is already having a disastrous effect on world food supplies and prices, and current technologies for biofuel production consume more energy than the fuels produce.

19.  Global Warming Hysteria is potentially linked to a stress-induced mental disorder.

20. In short, there is no “climate crisis” of any kind at work on our planet.

Retracing Antarctica’s glacial past

by Louisiana State University, September 25, 2018 in ScienceDaily

More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice — ice that was fully attached to the seafloor. As the planet warmed, the ice sheets melted and contracted, and sea level began to rise. Researchers have discovered new information that illuminates how and when this global phenomenon occurred.

…

More recently in 2002, in the northern part of Antarctica called the Antarctic Peninsula, the Larsen Ice Shelf collapsed. The collapse of this ice shelf quickly led to inland glaciers buttressed by the Larsen Ice Shelf to break up and melt. Scientists have thought that a similar process could have occurred when the Ross Ice Shelf collapsed thousands of years ago in the West Antarctic Ice Sheet.

However, Bart and colleagues from the University of South Florida, Auburn University and the Polish Academy of Sciences found that there was a centuries-long delay from when the Ross Ice Shelf collapsed and the grounded ice began to contract. In the Ross Sea, the delay was between 200 to 1,400 years later. This new information adds a layer of complexity for sea level rise computer simulations and predictions.

The ‘Trick’ of Anomalous Temperature Anomalies

by Kip Hansen, September 25, 2018 in WUWT

It seems that every time  we turn around, we are presented with a new Science Fact that such-and-so metric — Sea Level Rise, Global Average Surface Temperature, Ocean Heat Content, Polar Bear populations, Puffin populations — has changed dramatically — “It’s unprecedented!” — and these statements are often backed by a graph illustrating the sharp rise (or, in other cases, sharp fall) as the anomaly of the metric from some baseline.  In most cases, the anomaly is actually very small and the change is magnified by cranking up the y-axis to make this very small change appear to be a steep rise (or fall).

A Test of the Tropical 200- to 300-hPaWarming Rate in Climate Models

by R. McKitrick and J. Christy, July 6, 2018 in AGU100

Abstract
Overall climate sensitivity to CO2
doubling in a general circulation model results from a complex
system of parameterizations in combination with the underlying model structure. We refer to this as the model’smajor hypothesis, and we assume it to be testable. We explain four criteria that a valid test should meet: measurability, specificity, independence, and uniqueness. We argue that temperature change in the
tropical 200- to 300-hPa layer meets these criteria. Comparing modeled to observed trends over the past
60 years using a persistence-robust variance estimator shows that all models warm more rapidly than
observations and in the majority of individual cases the discrepancy is statistically significant. We argue that
this provides informative evidence against the major hypothesis in most current climate models.

The BBC’s Naive View of the UN’s Climate Machine

A recent internal document gives BBC journalists advice about how to report on climate matters. In Nova’s words, it declares that the “IPCC is God, can not be wrong.”

30 YEARS AGO OFFICIALS PREDICTED THE MALDIVES WOULD BE SWALLOWED BY THE SEA. IT DIDN’T HAPPEN

by Michael Bastasch, September 21, 2018 in TheDailyCaller

Environmental officials warned 30 years ago the Maldives could be completely covered by water due to global warming-induced sea level rise.

That didn’t happen. The Indian Ocean did not swallow the Maldives island chain as predicted by government officials in the 1980s.

In September 1988, the Agence France-Presse (AFP) reported a “gradual rise in average sea level is threatening to completely cover this Indian Ocean nation of 1196 small islands within the next 30 years,” based on predictions made by government officials.

Then-Environmental Affairs Director Hussein Shihab told AFP “an estimated rise of 20 to 30 centimetres in the next 20 to 40 years could be ‘catastrophic’ for most of the islands, which were no more than a metre above sea level.”

Arctic Ice Made Simple

by Ron Clutz, September 22, 2018 in ScienceMatters

People are overthinking and over-analyzing Arctic Ice extents, and getting wrapped around the axle (or should I say axis).  So let’s keep it simple and we can all readily understand what is happening up North.

I will use the ever popular NOAA dataset derived from satellite passive microwave sensors.  It sometimes understates the ice extents, but everyone refers to it and it is complete from 1979 to 2017.  Here’s what NOAA reports (in M km2):

“There Has Never Been An Energy Transition”

by David Middleton, September 20, 2018T in WUWT

One of my favorite sayings is, “We didn’t leave the Stone Age because we ran out of stones.”  Technically we never left the Stone Age because we use more rocks now than we did in the Stone Age.

And we never left the “Wood Age.”  There was no energy transition from biomass (wood) to fossil fuels. Coal piled on top of biomass, oil piled on top of coal and natural gas piled on top of oil

Scientists Throw Cold Water On Claims Linking Hurricane Florence To Global Warming

by M. Bastasch, September 19, 2018 in ClimateChangeDispatch

Hurricane Florence made landfall on Friday in North Carolina, bringing heavy rains and flooding. But before the storm touched down in the U.S., scientists and news outlets were already linking the storm to global warming.

However, not all scientists agree that man-made warming is making hurricanes, including Florence, bigger, slower and wetter as is often claimed in the media.

Climatologist Judith Curry called efforts by the “mainstream climate community” to link Florence to man-made global warming “woefully inadequate and misleading to scientists, the public and policymakers.”

Climategate continues: Release of University of Arizona Climate Emails Imminent

by Anthony Watts, September 19, 2018 in WUWT

Nearly seven years ago, on December 7th, 2011, the Free Market Environmental Law Clinic’s (FME Law) sought public records from the University of Arizona related to the Mann-Bradley-Hughes temperature reconstruction that looks like a hockey stick, and development of an Intergovernmental Panel on Climate Change (IPCC) report.  They refused much of the request and FME Law sued.  Now (on September 18th, 2018) legal counsel for the University informed FME Law that they were done, that they would be withdrawing their appeal of the trial court’s decision, end the case and disclose the records.

Included in the release will be emails that, for example, provide the full context of the discussions between Michael Mann and colleagues and Chick Keller on whether there was a medieval warm period and a little ice age.  Mann, Bradley and Hughes (MBH) were the authors of the “hockey stick” graph that became the icon of climate alarmism.  Dr. Keller was, at the time, Director of the Institute of Geophysics and Planetary Physics at the Los Alamos National Lab and affiliated with the University of California at San Diego, and wanted to reconcile data which appeared to refute the MBH papers.  Also within this collection will be the full discussion on events surrounding an effort to remove editors of journals willing to publish peer-reviewed papers that contradicted the MBH and related papers on which climate alarmism was built.  This collection of emails is particularly important in that they will provide the full context of Climategate emails that have been described as “cherry picking.”

COTES DE FLANDRE, SUBMERSIONS FAITS ET LEGENDES

Les côtes de Flandre n’ont pas toujours été aussi paisibles qu’aujourd’hui, et je n’oublie pas le raz-de-marée du 31 janvier 1953 qui toucha les Pays-Bas et notre littoral, faisant plus de 1800 morts et des dégâts considérables. (photo : à Ostende).

Pêchés dans diverses chroniques et ouvrages (notamment “La Flandre mystérieuse” de Saint Hilaire), j’en ai fait une compilation qui n’a bien entendu aucune prétention scientifique ou historique, mais ces événements avaient laissé une trace dans la mémoire populaire, trace qui a hélas fortement tendance à s’effacer.

How constant is the “solar constant?”

by Andy May, September 19, 2018 in WUWT

The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. These are long term values, estimated for the 261-year period 1750-2011 and they apply to the “baseline” of the Schwabe ~11-year solar (or sunspot) cycle, which we will simply call the “solar cycle” in this post. The baseline of the solar cycle is the issue since the peaks are known to vary. The Sun’s output (total solar irradiance or “TSI”) is known to vary at all time scales (Kopp 2016), the question is by how much. The magnitude of short-term changes, less than 11 years, in solar output are known relatively accurately, to better than ±0.1 W/m2. But, the magnitude of solar variability over longer periods of time is poorly understood. Yet, small changes in solar output over long periods of time can affect the Earth’s climate in significant ways (Eddy 1976) and (Eddy 2009).

Statistical study of past temperature records suggest possible undetected natural climate forcing cycles

by Anthony Watts, September 18, 2018 in WUWT

Godfrey Dack writes in with this:

Everyone will be familiar with the difficulty of listening to a conversation held with a friend in a crowded room with many other conversations going on at the same time. So it is with many fields of scientific investigation where it is difficult to tease a particular trend out from masses of data. In the first case, we could call the friend’s conversation ‘The Signal’, and the background conversations ‘The Noise’.

In looking at climate data, trends (the signal) can be graphically represented by a (generally) smooth curve, usually flanked by a range of experimentally predicted or actually measured values (the noise). Joining up every point on a graph of such data would give a jagged line which could be thought of as a combination of many alternating functions over a wide range of frequencies.

Negative climate feedback: more ships in the Arctic mean more cooling

by Anthony Watts, September 17, 2018 in WUWT

This article claim ships will “be able to sail right over the North Pole” by 2050 due to warming, but at the same time say ship tracks will make more clouds and cool the Arctic. Of course, anything is possible with the help of climate models.

More ships and more clouds mean cooling in the Arctic

With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole – something not previously possible for humankind.

Evolutions récentes du CO2 atmosphérique (1/3)

by J.C. Maurin, 16 septembre 2018, in Science,Climate,Energie

Dans les années 80, la découverte dans les archives glaciaires d’une corrélation entre température et taux de CO2 permit de soupçonner une influence anthropique sur le climat: les taux mesurés depuis 1958 étaient supérieurs aux taux des archives glaciaires.
L’IPPC (GIEC) fut créé en 1988 par 2 organismes: United Nations Environment Programme (UNEP) et  World Meteorological Organization (WMO). Le GIEC attribue l’intégralité de la hausse du taux de CO2 depuis un siècle à l’influence humaine.  Pour les dernières décennies, nous examinerons ici les mesures disponibles, les corrélations CO2 / température, enfin le modèle anthropique GIEC sera confronté à un modèle concurrent.

Hurricane Florence is not climate change or global warming. It’s just the weather.

by Roy W. Spencer, September 15, 2018 in USAToday

Even before Hurricane Florence made landfall somewhere near the border of North and South Carolina, predicted damage from potentially catastrophic flooding from the storm was already being blamed on global warming.

Writing for NBC News, Kristina Dahl contended, “With each new storm, we are forced to question whether this is our new, climate change-fueled reality, and to ask ourselves what we can do to minimize the toll from supercharged storms.”

The theory is that tropical cyclones have slowed down in their speed by about 10 percent over the past 70 years due to a retreat of the jet stream farther north, depriving storms of steering currents and making them stall and keep raining in one location. This is what happened with Hurricane Harvey in Houston last year.

But like most claims regarding global warming, the real effect is small, probably temporary, and most likely due to natural weather patterns …

Beyond Milankovitch

by Donald Rapp, September 8, 218 in Climate Etc.

On the terminations of Ice Ages.

Terminations occur on solar up-lobes

There is no doubt that there is merit in the widely accepted Milankovitch theory that Ice Ages and their terminations are controlled by solar input to the NH in mid-summer. It is also clear that relying on the solar input to the NH alone, does not adequately account for the occurrence of terminations of Ice Ages. The variation of solar input to high latitudes is modulated by precession, which produces continual up-lobes and down-lobes in solar input with a ~ 22,000-year period. While every termination is accompanied by the 5,500-year rising portion of an up-lobe in the solar input to high latitudes, many strong up-lobes do not produce a termination….

End of the Little Ice Age in the Alps forced by industrial black carbon

by Thomas H. Painter et al., September 17, 2018 in PNAS

The end of the Little Ice Age in the European Alps has long been a paradox to glaciology and climatology. Glaciers in the Alps began to retreat abruptly in the mid-19th century, but reconstructions of temperature and precipitation indicate that glaciers should have instead advanced into the 20th century. We observe that industrial black carbon in snow began to increase markedly in the mid-19th century and show with simulations that the associated increases in absorbed sunlight by black carbon in snow and snowmelt were of sufficient magnitude to cause this scale of glacier retreat. This hypothesis offers a physically based explanation for the glacier retreat that maintains consistency with the temperature and precipitation reconstructions.

Heat Analysis of NOAA Data Suggests the US Is Not Seeing Increased Warming

by Leland Park, September 13, 2018 in WUWT

Given the impending global warming crisis declared by scientists, it should be easy to unambiguously demonstrate the crisis from the instrumental record. Unfortunately, when looking at the  high temperature record for the US, it does not show any warming.

Figure 1 illustrates the incremental changes in surface air temperatures based on year to year differences in station average Tmax. The data is from all active stations in the US Historical Climatology Network (USHCN) from 1895 to 2014.

The classic heat equation defines changes in heat content as being proportional to changes in temperature (ΔQ = ƒ{ΔT} ).

Thus, Figure 1 amounts to a depiction of incremental changes in heat content, without scaling in energy units. The overall net temperature change is 0, which means the net change in heat content is also zero (ΔQ = ƒ{ΔT} = ƒ{0} = 0).

Evaluating the contribution of black carbon to climate change

by Nagoya University, September 11, 2018 in ScienceDaily

Black carbon refers to tiny carbon particles that form during incomplete combustion of carbon-based fuels. Black carbon particles absorb sunlight, so they are considered to contribute to global warming. However, the contribution of black carbon to the heating of the Earth’s atmosphere is currently uncertain. Models that can accurately assess the warming effect of black carbon on our atmosphere are needed so that we can understand the contribution of these tiny carbon particles to climate change. The mixing state of black carbon particles and their particle size strongly influence their ability to absorb sunlight, but current models have large uncertainties associated with both particle size and mixing state.

WUWT readers may recall that climate activists wanted the current epoch we live in to be named the “Anthropocene”, because they believe humans are the dominate force on the planet.
