The mainstream media love to lecture us daily about the coming apocalypse as a result of catastrophic climate change, but are we being told the complete story?

The climate Comms event of, at least this week, has arrived early due to a leak. The Vatican has released its view on the state of the planet. Much anticipated by some on both sides of the debate, the leak will no doubt leave the usual suspects scrambling to spin the Encyclical for all it is worth.

More pseudo-religious climate nonsense in Thursday’s Guardian:
Quote: ‘James Inhofe, infamous for tossing a snowball across the Senate floor to demonstrate ‘the greatest hoax ever perpetrated against the American people’, says Pope Francis should ‘stay with his job’ during a pitch to fellow unbelievers‘
The Guardian report later says: ‘In the world outside, anticipation was building for the pope to deliver his much-awaited encyclical next week, when he is expected to cast climate change as a moral issue.’

Two choices: whether to laugh or cry at the latest fortune-telling exercise from NASA’s warming-obsessed spin-doctors. Climate models are famed for their predictive inadequacy – incompetence even – so this looks exactly like an exercise in futility.
NASA has released a dataset setting out how rainfall and temperature patterns are likely to change in the coming decades, Gizmag reports. The data covers 21 climate models, mapping how our environment could change due to growing concentrations of greenhouse gases in the atmosphere.
A few weeks ago we put up a post to discuss the role of convection in the Earth’s atmosphere:
Beginner’s guide to convection cells
The introduction, linked to a short video, said:
‘When you warm air, it rises. Cool air will sink. This process of convection can lead to flows in the atmosphere, in a manner that we can illustrate [see video] on a small scale. Warm and cool air in a fish tank rise and fall; this motion is made visible by adding fog. Ultimately, the motion leads to a convection cell, with air rising, moving to the side, falling, and moving back. This heat-driven motion of air moves heat around in the atmosphere. It is also responsible for making the wind blow.’
That may have seemed straightforward to some, but a few hundred comments later controversy continues, so we’re starting a new post using this website for reference : Lapse Rate, Moisture, Clouds and Thunderstorms

Despite the fact that former climate guru James Hansen conceded there had been a temperature standstill in the current century, it’s now claimed by the NOAA that it was all a myth.
A reported pause in global warming—a mystery that has vexed scientists and delighted contrarians—was an illusion based on inadequate data, U.S. government researchers reported Thursday.
The findings by National Oceanic and Atmospheric Administration (NOAA) researchers that there was no warming “hiatus” over the past 15 years could reshape consensus science on recent climate change. The research undercuts an argument of pundits and politicians who oppose taking action.

Paul Vaughan has produced a six page .pdf document crammed with the fruits of his research into the ways in which solar variation affects Earth’s climate. Several of the observations and concepts coincide with the work we have been doing here at the talkshop over the last six years to unravel the mysteries of solar system dynamics and their effect on Terrestrial variation. Paul has applied his stats and visualisation skills and thorough approach to referencing, including direct links to data. This has resulted in a landmark document which readers will find both useful and inspiring. It demonstrates the progress that has been made in solar-terrestrial theory, (with hints about the underlying planetary solar relations too).

Relevant to current discussions on the talkshop concerning changes in Earth’s length of day (LOD) and the effect of planetary orbital resonances on the Moon’s orbital parameters and Earth climatic variation; this is a repost from Ian Wilson’s excellent Astro-Climate-Connection website. Ian very generously opens with a hat tip to this blog, (at which he is one of the ‘collaborators’ he mentions).
Connecting the Planetary Periodicities to Changes in the Earth’s LOD
Monday, October 14, 2013 : Ian Wilson PhD
[(*) Some of the findings in this blog post concerning the connection between the Earth’s rotation rate and the planetary configurations have also been independently discovered by Rog “Tallbloke” Tattersall and his collaborators]
A. The Connection Between Extreme Pergiean Spring Tides and Long-term Changes in the Earth’s Rotation Rate as Measured by the Rate-of-Change of its Length-of-Day (LOD). (*)
If you plot the rate of change of the Earth’s Length of Day (LOD) [with the short-term atmospheric component removed] against time [starting in 1962] you find that there is a ~ 6 year periodicity that is phase-locked with the 6 year period that it takes the lunar line-of-nodes to re-align with the lunar line-of-apse [see the first note directly below and reference  for a description of the method used to determine the time rate of change of LOD].
NB: The pro-grade precession of the lunar line-of-apse once around the Earth with respect to the stars takes 8.8504 Julian years (J2000) while the retrograde precession of the lunar
line-of-apse line-of-nodes once around the Earth with respect to the stars takes 18.6000 Julian years (J2000). Hence, the lunar line-of-apse and the ascending node of the lunar line-of-nodes will realign once every:
(18.6000 x 8.8504) / (18.6000 + 8.8504) = 5.9969 Julian years
Terradaily reports on the feel-good factor of green grass:
The heat is stifling, the soil dry as a bone, and a new law in drought-stricken California restricts the use of sprinklers.
But far from saying farewell to their beloved lawns, some Californians are coping with the drought by… painting them green.
With a simple squeeze of a spray gun, dried-out yellow grass regains its lush green color before the eyes of its proud owners.
It is a kind of make-over which is becoming increasingly common in California, which is now in the fourth year of a historic drought.

Let’s put this up for discussion as the dominant role of WV often gets buried in all the focus on man-made carbon dioxide emissions.
Originally posted on Musings from the Chiefio:
This posting just points to a very well done page that calculates the relative contributions to the greenhouse effect as used by the AGW thesis, by various gasses. In particular, it includes water vapor. The result is a conclusion that human caused CO2 is not relevant to global temperature. Something I have said before, but without the nice graphs and calculations.
It really is all about the water on our water world.
Water Vapor Rules the Greenhouse System
Just how much of the “Greenhouse Effect” is caused by human activity?
It is about 0.28%, if water vapor is taken into account– about 5.53%, if not.
This point is so crucial to the debate over global warming that how water vapor is or isn’t factored into an analysis of Earth’s greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.

Last winter parts of the USA received record snowfalls according to reports. While one winter is not a trend, it was also the second consecutive year of severe freezing of the Great Lakes on a scale not seen for decades.
A particularly harsh winter left many states over-budget on snow removal, with some having to kick in tens of millions in additional funding, according to a survey released Monday.
The survey of 23 states, conducted by the American Association of State Highway and Transportation Officials, found that combined spending on winter maintenance operations exceeded $1 billion for the period between October, 2014 and March, 2015, the Associated Press reports.

Science Daily reports on recent research by Oregon State University (H/T The Hockeyshtick):
A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture of the link between climate in the northern and southern hemispheres.
Greenland climate during the last ice age was very unstable, the researchers say, characterized by a number of large, abrupt changes in mean annual temperature that each occurred within several decades. These so-called “Dansgaard-Oeschger events” took place every few thousand years during the last ice age. Temperature changes in Antarctica showed an opposite pattern, with Antarctica cooling when Greenland was warm, and vice versa.
In this study funded by the National Science Foundation and published this week in the journal Nature, the researchers discovered that the abrupt climates changes show up first in Greenland, with the response to the Antarctic climate delayed by about 200 years. The researchers documented 18 abrupt climate events during the past 68,000 years.

The New York Times reports the difficulties likely to face US power generation companies due to the pace of change demanded by the latest government rules and the ever-increasing reliance on part-time power sources scattered all over the place. Does this sound familiar at all?
WASHINGTON — As President Obama prepares to unveil his climate change regulations on coal-fired power plants, the nation’s electric utilities are preparing to transform the system that keeps the lights on in America. But some companies fear that in the process, the lights may go out.

I recently came across this comment:
“During the height of the day at the equator, 1361 joules/m2/second (less 30% Albedo) is coming in from the Sun but the surface temperature only increases as if 0.0017 joules/m2/second is absorbed (or impacts the temperature at 2 meters). The extra 959.9983 joules/m2/second flows away from the surface effectively almost as fast as the energy is coming in.
Your calculator says surface temperatures should increase to 87C.
At night, virtually no radiation is coming in (and the upwelling less downwelling radiation) says the surface should be losing about 100 joules/m2/second but it actually only loses 0.001 joules/m2/second.
This is the real-world now versus the theoretical.” Bill Illis

Any guesses how this one’s likely to go? The idea that humans can control temperature changes is about as absurd as the idea that they are the main cause of them, as large fluctuations in long-term climate records clearly show. The prospect of maximum temperatures being set by law is risible – but in theory it could happen.
Phys.org reports: Around 900 Dutch citizens on Tuesday took their government to court in a bid to force a reduction in greenhouse gas emissions and take action against climate change.
“We want the Dutch government to reduce greenhouse gas emissions by 40 percent by 2020 compared to 1990 levels,” said Majan Missema, head of rights group Urgenda which is coordinating the legal action.
The group says the case is the first in Europe in which citizens attempt to hold a state responsible for its potentially devastating inaction and the first in the world in which human rights are used as a legal basis to protect citizens against climate change.

1938 atmospheric river that caused the Los Angeles flood of 1938
At least one person asked why I used a reanalysis that does not assimilate satellite water vapor data to study an atmospheric river (AR) event.
That’s a good question because the NOAA/CIRES Twentieth Century Global Reanalysis Version 2c (20thCR V2c) only ingests three things: surface pressure, sea ice coverage and sea surface temperature. The rest of the analysis is generated by the physical models of NOAA’s Global Forecast System (GFS).

The idea that shipping could be releasing heat from the oceans has not been discussed much before.
Originally posted on Science Matters:
In response to my water world post, I was shown the wonderful phrase coined by Dr. Bernaerts:
“Climate is the continuation of oceans by other means”.
In was in 1992 he wrote in Nature appealing to the Rio conference to use the UN Convention on the Law of the Seas (UNCLOS) to better manage human impacts on the oceans, and thereby address climate concerns. Needless to say, that call fell on deaf ears.
He later elaborates: “Presumably science would serve the general public better when they would listen to Leonardo da Vinci (1452-1519) who said: “Water is the driver of nature”. Some say that nature rules climate, but water rules the nature on this earth, and the water on earth is so synonymous with the oceans and seas that it can be said: Climate is the continuation of the oceans by other means.”
Dr. Bernaerts is certainly a man worthy of…

Trend or exception: after two consecutive winters with 90% freeze-overs of the North American Great Lakes, plus this assessment(see below), what are the chances of an ‘Arctic death spiral’ as trumpeted in certain quarters over recent years?
Christopher Booker reports in the Sunday Telegraph (h/t GWPF):
As Britain emerges from an unusually sunny and comparatively mild winter, spare a thought for the people of eastern Canada, still in the grip of their most terrifying winter for decades. Recent pictures online of “Photographic proof that Canada’s east coast is basically the ice planet Hoth” show hapless residents standing below ice cliffs and snow drifts 20ft high. This month the Globe and Mail of Toronto, which endured its coldest February on record, described 2015 for Canada’s Atlantic provinces as having been like living in a “prison of snow and ice”.

If temperatures won’t go up, bring the so-called ‘target’ down. That’s the latest brainwave of climate fear merchants, seemingly oblivious to the lack of any temperature rise this century.
Former Guardian writer Fred Pearce reports:
Is the world’s target of limiting global warming to 2 °C too high, or too low? Does it even make scientific sense? The consensus around the target, which was agreed at climate talks in Copenhagen in 2009, seems to be coming unstuck.
Back in October, US climate analysts David Victor and Charles Kennel called it scientifically meaningless and politically unachievable. We should get used to the idea of something warmer, they said.
Now the target has been denounced as “utterly inadequate”, by Petra Tschakert of Penn State University in University Park, who has been involved in a UN review of the target. She wants a 1.5 °C target instead. Writing in the journal Climate Change Responses, she says this lower limit is necessary if we want sea levels to rise less than a metre, to protect half of all coral reefs, and to still have some ice during Arctic summers.
