Bahrain hits (black) gold with biggest shale discovery in world

by Catherine Philp, April 5, 2018 in TheTimes

Sheikh Mohammed bin Khalifa al-Khalifa said it was not yet known how much of the oil could be extracted. The scale of the find, however, is about to make it a big player in the global market, significantly boosting its economy and raising its profile in the region, where it plays a smaller fiddle to its giant neighbour, Saudi Arabia.

Science is Not Truth

by Donna Laframboise, April 4, 2018 in ClimateChangeDispatch

SPOTLIGHT: As the influence of religion has waned, we’ve placed science on a pedestal – mistaking it for an oracle of truth.

BIG PICTURE: Richard Harris has written a startling book about the state of medical research. The preface to Rigor Mortis: How Sloppy Science Creates Worthless Cures, Crushes Hope, and Wastes Billions includes a warning about scientific naivety:

Most of science is built on inference rather than direct observation…Science progresses by testing ideas indirectly, throwing out the ones that seem wrong…Gradually, scientists build stories that do a better job of approximating the truth.

Earth’s stable temperature past suggests other planets could also sustain life

by Anthony Watts,  April 3, 2018 in WUWT

Theories about the early days of our planet’s history vary wildly. Some studies have painted the picture of a snowball Earth, when much of its surface was frozen. Other theories have included periods that would be inhospitably hot for most current lifeforms to survive.

New research from the University of Washington suggests a milder youth for our planet. An analysis of temperature through early Earth’s history, published the week of April 2 in the Proceedings of the National Academy of Sciences, supports more moderate average temperatures throughout the billions of years when life slowly emerged on Earth.

A new coal war frontier emerges as China and Japan compete for energy projects in Southeast Asia

by P. Homewood, April 3, 2018 in NotaLotofPeopleKnowThat

A joint report by Greenpeace, the Sierra Club and CoalSwarm indicates that Southeast Asia will be the new epicentre of coal production. Asia accounts for 85 per cent of new coal power development in the world’s top 20 coal producing countries, with China as the leader of the pack. However, while tighter restrictions on domestic coal plants have been imposed by the central government to curb pollution, Beijing has pushed the development of high-efficiency, low-emission coal plants across Southeast Asia as part of the “Belt and Road Initiative”.

As China is expanding its influence, Beijing’s foremost strategic competitor in Asia, Japan, is being forced to step up efforts to combat its shrinking influence in the region. The booming energy sector of Southeast Asia, especially coal, is proving to be the new front line in the geopolitical rivalry between Asia’s two industrial giants.

Antarctic Temperature Data Contradict Global Warming…”Much Warmer” 105 Years Ago!

by P. Gosselin, April 3 , 2018 in NoTricksZone

Despite all the alarmist claims of an Antarctic meltdown, it is well known that the trend for sea ice extent at the South Pole has been one of growing ice rather than shrinking ice over the past 4 decades.

Naturally many factors influence polar sea ice extent, such as weather patterns, winds, ocean currents and sea surface temperature cycles. One factor of course is also surface air temperature, which according to global warming theorists is rising globally (…)

Ocean Temps Falling Feb. 2018

by Ron Clutz, March, 2018 in ScienceMatters

The best context for understanding decadal temperature changes comes from the world’s sea surface temperatures (SST), for several reasons:

  • The ocean covers 71% of the globe and drives average temperatures;
  • SSTs have a constant water content, (unlike air temperatures), so give a better reading of heat content variations;
  • A major El Nino was the dominant climate feature in recent years.

HadSST is generally regarded as the best of the global SST data sets, and so the temperature story here comes from that source, the latest version being HadSST3.  More on what distinguishes HadSST3 from other SST products at the end.

Climate-Related Deaths Down by 98.9%; Last Year All-Time Low

by Bjorn Lomborg, April 2, 2018 in ClimateChangeDispatsch

CCD Editor’s Note: In 1920, CO2 levels were 303 PPM or 0.03%. Last year they were 406 PPM or 0.04%. Despite our global population quadrupling, climate deaths have actually gone down as CO2 levels have gone up. Lomborg explains why with the now-standard, often-by-rote “this does not mean that there is no global warming” caveat.

The Sahara Is Growing (Even Though It’s Wetter & Greener!)

by P. Homewood, April 1, 2018 in NotaLotofPeopleKnowThat

The green shoots of recovery are showing up on satellite images of regions including the Sahel, a semi-desert zone bordering the Sahara to the south that stretches some 2,400 miles (3,860 kilometers).

Images taken between 1982 and 2002 revealed extensive regreening throughout the Sahel, according to a new study in the journal Biogeosciences.

The study suggests huge increases in vegetation in areas including central Chad and western Sudan.

Weekly Climate and Energy News Roundup #310

THIS WEEK: By Ken Haapala, President

California Litigation, Monckton: Last week’s TWTW discussed on the public nuisance lawsuits by San Francisco and Oakland against oil companies claiming carbon dioxide (CO2)-caused global warming / climate change will cause harm in the future. It focused on the filing amicus curiae (friend of the court) brief by three distinguished Professors of Physics – William Happer, Steven Koonin and Richard Lindzen (Three Profs). The brief accepted the data and evidence used by the UN Intergovernmental Panel on Climate Change (IPCC) in its Fifth Assessment Report (AR5) and the Climate Science Special Report (CSSR) by the US Global Change Research Program (USGCRP). However, the Three Profs demonstrate the conclusions in the reports are not established, and, at best, premature. They assert:

Uh oh– analysis of GHCN climate stations shows there is no statistically significant warming – or cooling

by Mark Fife, April1, 2018 in WUWT

This is my eighth post in this series where I am examining long term temperature records for the period 1900 to 2011 contained in the Global Historical Climatology Network daily temperature records. I would encourage anyone to start at the first post and go forward. However, this post will serve as a standalone document. In this post I have taken my experience in exploring the history of Australia and applied it forward to cover North America and Europe.

The way to view this study is literally a statistic-based survey of the data. Meaning I have created a statistic to quantify, rank, and categorize the data. My statistic is very straight forward; it is simply the net change in temperature between the first and last 10 years of 1900 through 2011 for each station.

Climate Science Integrity And Intelligence At All Time Record Low

By Tony Heller, April 1, 2018 in TheDeplorableClimSciBlog

With temperatures of -30C and Arctic sea ice nearing its winter maximum, government climate scientists and their useful idiots in the press announce that Arctic sea ice is “near an all time low.”

In the actual Arctic, sea ice extent is increasing, more than

double six months ago, and essentially identical to all recent years (…)

Lake Chad Might Be Shrinking, But It Has Nothing To Do With Climate Change

by P. Homewood, April 1, 2018 in NotaLotofPeopleKnowThat

Lake Chad – a source of water to millions of people in West Africa – has shrunk by nine-tenths due to climate change, population growth and irrigation. But can a scheme dating back to the 1980s save it?

“It’s a ridiculous plan and it will never happen.” That’s the reaction many people have to the idea of trying to fill up Lake Chad and restore it to its former ocean-like glory by diverting water from the Congo river system 2,400km (1,500 miles) away.

Tools to Spot the Spots

by Willy Eschenbach, March 30, 2018 in WUWT

People have asked about the tools that I use to look for any signature of sunspot-related solar variations in climate datasets. They’ve wondered whether these tools are up to the task. What I use are periodograms and Complete Ensemble Empirical Mode Decomposition (CEEMD). Periodograms show how much strength there is at various cycle lengths (periods) in a given signal. CEEMD decomposes a signal into underlying simpler signals.

Now, a lot of folks seem to think that they can determine whether a climate dataset is related to the sunspot cycle simply by looking at a graph. So, here’s a test of that ability. Below is recent sunspot data, along with four datasets A, B, C, and D. The question is, which of the four datasets (if any) is affected by sunspots?

Snow Cover, Ice Volume Growth Show Global Climate Is A Lot More Than Just “Surface Temperature”

by P.  Gosselin, March 30, 2018 in NoTricksZone

Although a number of scientists are hollering that 2017 was “among the warmest on record”, we are not seeing any manifestation of this, at least over the northern hemisphere, where ironically snow and ice have shown surprising extents. This year the northern hemisphere winter has been surprisingly cold and brutal over a number of regions.

On March 20, 2018, northern hemisphere snow and ice cover was over 1 standard deviation above normal. Source: Environment Canada.

Once we can capture CO2 emissions, here’s what we could do with it

by Cell Press, March 29, 2018 in ScienceDaily

The thousands of metric tons of carbon dioxide (CO2) emitted from power plants each year doesn’t have to go into the atmosphere. Researchers are optimistic that within the next decade we will be able to affordably capture CO2 waste and convert it into useful molecules for feedstock, biofuels, pharmaceuticals, or renewable fuels. On March 29 in the journal Joule, a team of Canadian and US scientists describe their vision for what we should make with CO2 and how we can make it.

The two strongest potentially credible constraints, and conclusions

In Part 1 of this article the nature and validity of emergent constraints[1] on equilibrium climate sensitivity (ECS) in GCMs were discussed, drawing mainly on the analysis and assessment of 19 such constraints in Caldwell et al. (2018),[2] who concluded that only four of them were credible. An extract of the rows of Table 1 of Part 1 detailing those four emergent constraints is given below.[3]

Modern Warming – Climate Variability or Climate Change?

by  Renee Hannon, March 28, 2018 in WUWT

In the mid-1900’s many scientists were suggesting the Earth was cooling. Now scientists are forecasting global warming. Indeed, instrumental data shows global temperatures warmed by approximately 1-degree C during the past 165+ years. With warming rates of 0.5 to over 1.3 degrees C per century this has caused considerable alarm for many. This recent warming is commonly attributed to increasing greenhouse gases, primarily CO2.

This post examines natural paleoclimate trends and simple characteristics of past and present climate cycles at different time scales.

Little is known about the ice age human occupation of the Pacific Coast of Canada. Here we present the results of a targeted investigation of a late Pleistocene shoreline on Calvert Island, British Columbia. Drawing upon existing geomorphic information that sea level in the area was 2–3 m lower than present between 14,000 and 11,000 years ago, we began a systematic search for archaeological remains dating to this time period beneath intertidal beach sediments (…)

German CO2 equivalent emissions refuse to budge 10 straight years running, despite hundreds of BILLIONS invested in green energies.

As we have been hearing recently, global CO2 emissions continue their steady climb, despite the trillions of dollars committed to green energy sources worldwide and efforts to curb CO2 emissions.
