Friday Funny- Welcome to the Anthropocene Narcisscene

by Mark Sagoff, June 29, 2018 in WUWT


In view of the glacial pace of geologic events and the time it takes for things to turn into rock or become encased in it, you might think there would be no hurry to name a new geologic epoch, especially because the current one, the Holocene, started only about 11,500 years ago. You would be wrong. In 2002, Crutzen published an article in Nature magazine, “Geology of Mankind,” which called on geologists “to assign the term ‘Anthropocene’ to the present, in many ways human-dominated, geological epoch, supplementing the Holocene — the warm period of the past 10–12 millennia” and the beginning of which roughly coincided with the advent of human agriculture.The idea of the Anthropocene, which Earth system scientists initiated and advocated, landed like a meteor, setting off a stampede among academics. Nature followed with an editorial that urged that the Anthropocene be added to the geologic timescale. “The first step is to recognize,” Nature editorialized, “that we are in the driver’s seat.”

New Met Office study suggests natural factors, including the sun, are the biggest reason behind “the pause”

by Anthony Watts, June 7, 2018 in WUWT


More excuses for “the pause”.

A team of researchers from the U.K. Met Office, Sweden and Australia has found that three periods of global warming slowdown since 1891 were likely due to natural causes rather than disruptions to the factors causing global warming. In their paper published on the open access site Science Advances, the group describes their study of global mean surface temperatures (GMST) since the late 19th century and what they found.

In this new paper, the researchers looked at GMST as registered by multiple sources around the globe over the past 127 years, noting the slow march of temperature increases. More specifically, they noted the three previously identified slowdowns in GMST increases—the time periods from 1896 to 1910, from 1941 to 1975, and then from 1998 to 2013. They then looked at factors that could have contributed to these slowdowns and found natural causes for each. (…)

Manmade pollutants now blamed for global cooling

by Michael Haverluck, January 28, 2018 in NewsNow


Climate flip-flop

After finally realizing that the claimed rising temperatures never showed up around the globe, the scientific community is being told through its most respected publications that specific forms of pollution that are human-generated are keeping populations from experiencing the toll of other airborne human-made emissions.

“Pollution in the atmosphere is having an unexpected consequence, scientists say – it’s helping to cool the climate, masking some of the global warming that’s occurred so far,” Scientific American reported last week. “That means efforts worldwide to clean up the air may cause an increase in warming, as well as other climate effects, as this pollution disappears.”

Giant clams tell the story of past typhoons

by Hokkaido University, May 24, 2018 in ScienceDaily


A highly precise method to determine past typhoon occurrences from giant clam shells has been developed, with the hope of using this method to predict future cyclone activity.

A team of researchers led by Tsuyoshi Watanabe of Hokkaido University has discovered that giant clams record short-term environmental changes, such as those caused by typhoons, in their shells. Analyzing the shell’s microstructure and chemical composition could reveal data about typhoons that occurred before written records were available… (…)

More Irrefutable Evidence of Small Island Stability In the Face of Climate Change

by Duvat et al.  2017, Global&Planetary Change in CO2Science


Writing as background for their study, Duvat et al. (2017) state that “it has commonly been considered that atoll reef islands would disappear under climate change, as a result of sea-level rise and induced accelerating shoreline erosion,” citing the works of Connell (2003), Dickinson (2009) and McAdam (2010). This perception is based on model predictions, which have been hyped all over the globe, especially among politicians and the media, some of whom demand reparations for small island States who they fear will be forced to abandon their islands within decades.

But how much faith should one place in such projections and concerns?

According to Duvat et al., not that much … (…)

The gypsum gravity chute: A phytoplankton-elevator to the ocean floor

by

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, May 22, 2018 in ScienceDaily


When marine algae die, they usually float in slow motion to the ocean’s depths. However, during an expedition with the research icebreaker Polarstern to the Arctic in the spring of 2015, scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) discovered a phenomenon that significantly accelerate this transport: tiny gypsum crystals, which form during the freezing of salt in the porous spaces of Arctic sea ice, weigh down the phytoplankton like heavy ballast, pulling them to the bottom within a matter of hours. The effect is like an express elevator for the carbon they contain. “This mechanism was previously completely unknown,” says marine bio-geologist Dr Jutta Wollenburg … (…)

US gas lobby chief: A lot of LNG can come to Europe through Poland

by Pavol Szalai, May 21, 2018 in Euractiv


There is a strong possibility that Poland will build a floating Liquefied Natural Gas (LNG) terminal in Gdańsk, according to Fred H. Hutchison, who says “a lot of gas” can come to Central European markets this way.

Fred H. Hutchison is president and CEO of LNG Allies, an industry association working to expedite and maximise US exports of liquefied natural gas (LNG). In Bratislava, Hutchinson gave a speech at the Energy Committee of the American Chamber of Commerce.

Imports of natural gas from Russia have increased over the years and represented 34% of EU’s supply in 2016 according to ACER. Given the cheap price of Russian gas, do you see a window of opportunity for Amercian LNG on the European market?

What global warming? How about global cooling

by M. Khandekar, April 27, 2018 in TroyMedia


It’s been a long winter.

I should know. I’m a former climate research scientist at Environment Canada. And I was an expert reviewer for the United Nations’ International Panel on Climate Change (IPCC) and its 2007 Climate Change Report.

The wintry weather held its grip over most of Canada well into April, from Vancouver to St. John’s, as snow, freezing rain, ice pellets and ferocious winds hammered everyone. A few noteworthy wintry tales:

  • Calgary is set for record snowfall.

  • Edmonton set a record for continuous days of below-freezing temperatures this winter.

  • Most of the Canadian Prairies were still in winter-like weather mode in mid-April.

  • Toronto has recorded one of the highest numbers of Heating Degree Days at 3,485 and counting.

  • Atlantic Canada braced for more wintry weather with snow accumulation of 10 to 25 cm in mid-month.

This year’s winter could be the longest, snowiest and coldest in 40 years.

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.

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.
