Can Humans Melt the Antarctic Icecap?

by Julius Sanks, April 16, 2018 in WUWT


When discussing climate with people who do not have technical backgrounds, I have learned much of the climate discussion is a foreign language to them.

So, I take them through a few examples of how much energy is involved and how miniscule human activity is by comparison. Done properly, this lets a non-STEM person grasp the huge amounts of energy involved.

One of my favorites is Anthony’s essay that debunks the Hiroshima equivalent alarmism:

CHALLENGING THE SCIENCE BASIS OF THE PARIS CLIMATE AGREEMENT

by Antero Ollila, April 16 in WUWT


 

COP21 does not define the scientific basis of the agreement for the warming effects of the anthropogenic emissions, but it refers to a scenario. This scenario has not been defined in the COP21, but it can be found. The scientific resource of United Nations as well as of the COP21 is IPCC. The exact specification of IPCC is (Summary for Policymakers. In: Climate Change 2014. Mitigation of Climate Change”): “Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels (range based on median climate response; the range is 2.5 °C to 7.8 °C when including climate uncertainty)”. Even though IPCC refers to multiple scenarios in the text above, the surface temperature increase to the average value of 4.25 ⁰C means one scenario only.

10 new islands formed in the last 20 years

by Sidney Stevens, July 5, 2016 in mother.nature.network


Yes, islands are disappearing — most recently the five Solomon Islands lost to rising sea levels. But don’t despair just yet. For every island that goes the way of the dodo bird, the Earth is busy creating new islands.

Some erupt into being through volcanic activity. Others grow from ocean sandbars. Still others reveal themselves after glaciers retreat. A few are only temporary, while some materialize and erode on a regular basis. However they’re birthed and however long they last, island-building is part of the amazing mystery of our living, breathing planet.

Here are 10 of Mother Nature’s newest islands formed in the past two decades (and one still in the embryonic stage).

Largest High-Arctic Lake Melting From Geothermal Heat, Not Global Warming

by James E. Kamis, April 16, 2018  in ClimateChangeDispatch


Recent changes to Lake Hazen, the world’s largest high-Arctic lake, are from increased heat flow from the area’s known geological features, and not from global warming as per the many alarmist media reports.

Evidence supporting this is abundant and reliable.

Northeast Canada’s Lake Hazen lies adjacent to the world-class Greenland/Iceland mantle plume.

Unusual climate during Roman times plunged Eurasia into hunger and disease

by S. Writers,  April 16, 2018 in TerraDaily


A recent study published in an esteemed academic journal indicates that volcanic eruptions in the mid 500s resulted in an unusually gloomy and cold period. A joint research project of the Chronology Laboratory of the Finnish Museum of Natural History and Natural Resources Institute Finland (Luke) suggests that the years 536 and 541-544 CE were very difficult for many people.

Easter Island’s “ecological suicide” – myths and realities

by Dennis Avery,  April 7, 2018 in WUWT


In a recent New York Times column, Nicholas Kristof misleads us about the awful history of Easter Island (2,300 miles west of Chile), whose vegetation disappeared in the cold drought of the Little Ice Age. In doing so, he blinds modern society to the abrupt, icy climate challenge that lies in our own future.

Kristof repeats the archaeological myth that Easter Island’s natives committed “ecological suicide,” by cutting down all their palm trees. They supposedly used the logs as rollers to move their famous huge statues. Afterward, they could no longer build canoes to catch the fish that were their key protein source. Worse, he says, clearing the trees resulted in so much soil erosion that most of the population starved and/or killed each other in famine-driven desperation (…)

Solar activity over nine millennia: A consistent multi-proxy reconstruction

by C.J. Wu et al., April 5, 2018 in Astronomy&Astrophysics


.pdf (13 pages)

The solar activity in the past millennia can only be reconstructed from cosmogenic radionuclide proxy records in terrestrial archives. However, because of the diversity of the proxy archives, it is difficult to build a homogeneous reconstruction. All previous studies were based on individual, sometimes statistically averaged, proxy datasets. Here we aim to provide a new consistent multi- proxy reconstruction of the solar activity over the last 9000 years, using all available long-span datasets of 10Be and 14C in terrestrial archives.

Sea level rise acceleration (or not): Part VII U.S. coastal impacts

by Judith Curry, April 15, 2018 in Climate.Etc.


Global mean sea level (GMSL) has increased by about 8–9 inches since 1880, with about 3 inches occurring since 1993. As discussed in Part VI, scientists expect that GMSL will continue to rise well beyond the 21st century because of global warming that has already occurred and warming that is yet to occur.

The recent NOAA Report Global and Regional Sea Level Rise Scenarios for the United States has stated that even the relatively small increases in sea level over the last several decades have been associated greater storm impacts at many places along the U.S. coast. Further, the frequency of intermittent flooding associated with unusually high tides has increased rapidly in response to increases in local sea level, becoming a recurrent and disruptive problem.

Svensmark: “Global Warming Stopped And A Cooling Is Beginning” – “Enjoy Global Warming While It Lasts”

by H.. Svensmark, June1 , 2016 in Principia.Sci.International


The star that keeps us alive has, over the last few years, been almost free of sunspots, which are the usual signs of the Sun’s magnetic activity. Last week [4 September 2009] the scientific team behind the satellite SOHO (Solar and Heliospheric Observatory) reported, “It is likely that the current year’s number of blank days will be the longest in about 100 years.” Everything indicates that the Sun is going into some kind of hibernation, and the obvious question is what significance that has for us on Earth.

If you ask the Intergovernmental Panel on Climate Change (IPCC) which represents the current consensus on climate change, the answer is a reassuring “nothing”. But history and recent research suggest that is probably completely wrong. Why? Let’s take a closer look.

Journalism On Thin Ice…New York Times Misses Ton Of Recent, Positive Findings In Polar Bear Story

by P. Gosselin, April 14, 2018 in NoTricksZone


The New York Times recently published an article penned by Erica Goode on the controversial Harvey et al paper, where 14 scientists (sophomorically) attacked polar bear researcher Susan Crockford and climate science skeptics.

Sloppy biased journalism

So it is no surprise that Erica Goode at the New York Times sided up with the 14 scientists of the Harvey publication to attack the so-called climate “denialists” in her most recent article. Unfortunately Goode made the fatal journalistic error of failing to keep a healthy distance from the alarmist side and as a result was blinded from seeing the glaring mountain of scientific research showing polar bears are in fact doing fine.

A conversation with Dr. Willie Soon – on polar bears, the sun, and Earth’s climate

by Dr. Willie Soon, April 14, 2018 in WUWT

Dr. Willie Soon is an independent solar physicist at the Harvard-Smithsonian Center for Astrophysics who has been studying the Sun and its influence on the Earth’s climate for more than a quarter of a century. A short while ago, he had a conversation with Mr. Grégoire Canlorbe, an independent journalist who is also vice president of the French Parti National-Libéral (“National-Liberal Party,” conservative, nationalist, and free-marketist). Here Dr. Soon speaks for himself. 

Canlorbe: You say polar bears are far less endangered by global warming than by environmentalists dreading ice melt. Could you expand?

Aussie PM: Coal to Hydrogen Plant Part of the Seamless Transition to Clean Energy

by Eric Worrall, April 13, 2018 in WUWT


h/t Geoff Sherrington – Coal is being rehabilitated as an essential component of the clean energy future.

Read more: http://www.abc.net.au/news/2018-04-12/coal-to-hydrogen-trial-for-latrobe-valley/9643570

Coal to hydrogen is not a new idea, the Water-gas shift reaction was discovered in 1780 by Italian Chemist Felice Fontana.

There are still some kinks to be worked out. The process to generate hydrogen from coal produces a monstrous amount of CO2 – far more CO2 per unit of useful energy than simply burning the coal would produce. But with hydrogen production, unlike hydrocarbon combustion, all the CO2 is produced in one place. This creates an opportunity for carbon sequestration, when technologies to sequester carbon on such an impressive scale are developed.

Mountain erosion may add CO2 to the atmosphere

by Woods Hole Oceanographic Institution, April 12, 2018 in ScienceDaily


Scientists have long known that steep mountain ranges can draw carbon dioxide (CO2) out of the atmosphere — as erosion exposes new rock, it also starts a chemical reaction between minerals on hill slopes and CO2 in the air, ‘weathering’ the rock and using CO2 to produce carbonate minerals like calcite.

Coal dead? Peak oil demand? Five takes on fossil fuels’ future

by Joe Ryan, April 12, 2018 in Bloomberg.News


(Bloomberg) — For all the buzz around wind, solar and electric cars, energy company executives had plenty to say Tuesday about the continuing role of fossil fuels and nuclear power at the Bloomberg New Energy Finance Future of Energy Summit.

Mining mogul Bob Murray offered a passionate defense of coal, asserting that we’d all “die in the dark” without it. Ethan Zindler, a Bloomberg New Energy Finance analyst, supplied the counter argument, saying U.S. coal-plant economics simply don’t work anymore. Here’s what executives from BP Plc to Tellurian Inc. said about the future of fossil fuels in a world pushing to fight climate change.

“Welcome to the Fabulous Anthropocene!”

by D. Middleton, April 12, 2018 in WUWT


Just to demonstrate that the American Association of Petroleum Geologists (AAPG) maintains an open mind about things, I thought I would share an recent AAPG Explorerarticle on the notion of establishing a formal geological epoch in honor of human beings…

I genuinely believe that these folks simply can’t grasp the concept of resolution.  This is a pervasive problem in the climate “science” community and will continued to feed claims of “unprecedented” changes in [fill in the blank] until we have about 1,000 years of high resolution instrumental data.

It appears Solar Cycle 25 has begun – Solar cycle 24 one of the shortest and weakest ever

by A. Watts, April 12, 2018 in WUWT


Evidence of a Cycle 25 sunspot found

In our previous post: Solar activity crashes – the Sun looks like a cueball, 

Our resident solar physicist, Dr. Leif Svalgaard commented and provided a link to something reported by his colleagues, something that likely would not have been possible without the fantastic solar observations of NASA’s Solar Dynamic Observeratory (SDO).

It seems a small sunspot has been observed, that has the opposite polarity of cycle 24 sunspots.

70+ Papers: Holocene Sea Levels 2 Meters Higher – Today’s Sea Level Change Indistinguishable From Noise

by K. Richard, April 12, 2018 in NoTricksZone


More than 70 recent scientific publications show that there is absolutely nothing unusual about the magnitude and rapidity of today’s sea level changes. These academically peer-reviewed papers show that sea levels were on average 2 meters higher earlier in the Holocene than they are today.

New Zealand halts new offshore oil, gas exploration permits

by Rick Wilkinson, April 12, 2018 in Oil&GasJournal


The New Zealand government has made the surprise announcement that it will not grant any new permits for offshore oil and gas exploration.

The Labor government of Prime Minister Jacinda Ardern said the move would not be retrospective. The country’s 22 existing offshore exploration permits along with any discoveries made in them could still lead to the granting of production licenses of up to 40 years duration.

Science Fact: Per NOAA, “Global Warming” Pause For U.S. Now Exceeds 22 Years (Wrong?)

by C3 Headlines, April 2018


The chart above was produced by NOAA at their ‘Climate at a Glance’ web page. In the upper right corner of the chart, NOAA shows its calculated per decade trend of -0.02°F for a period that spans 1996-2018.

After posting this chart and an accompanying article, it just seemed that something was likely wrong with the trend calculation produced by NOAA’s web site.

Scientists discover first super salty subglacial lakes in Canadian Arctic

by University of Alberta, April 11, 2018 in ScienceDaily


Super salty water beneath ice could serve as a terrestrial analogue for a habitat for life on other planets.

An analysis of radar data led scientists to an unexpected discovery of two lakes located beneath 550 to 750 meters of ice underneath the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic. They are thought to be the first isolated hypersaline subglacial lakes in the world.

New study reveals increased snowfall in Antarctica over last two centuries

British Antarctic Survey, April 9, 2018


Presenting this week (Monday 9 April 2018) at the European Geosciences Union (EGU) meeting in Vienna, an international team, led by British Antarctic Survey, describes how analysis of 79 ice cores collected from across Antarctica reveals a 10% increase in over the last 200 years.  This is equivalent to 272 giga tonnes of water – double the volume of the Dead Sea.

Lead author and ice core scientist Dr Liz Thomas from British Antarctic Survey explains: (…)

 

During The 800s-1300s AD, Wine Grapes Were Grown At Latitudes Where Polar Bears Now Roam

by K. Richard, April 2, 2018


Canada’s stable-to-increasing polar bear population extends its range slightly further south of the 55th parallel (York et al., 2016).

According to published geological evidence from the 1950s, remnants of wine grape vineyards have been unearthed in regions as far north as the polar-bear-inhabiting 55th parallel during the Medieval Warm Period (~800s to 1300s AD).
