Good news for the rest of humanity may be bad news for climate miserablists, but hey-ho. Another global warming canard takes a knock.

The Pacific’s low-lying reef islands are likely to change shape in response to climate change, rather than simply sinking beneath rising seas and becoming uninhabitable as previously assumed, new research has found.

Atoll nations such as Tuvalu, Tokelau and Kiribati lie only a few metres above sea level and are considered the world’s most vulnerable to global warming, with fears their populations will become climate refugees as waters rise, says Phys.org.

But a study published this week found that such islands “morphodynamically respond” to the environment because they are composed of the skeletal remains of tiny reef-dwelling organisms, rather than solid rock.

First the report, then a brief Talkshop analysis.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star, reports MessageToEagle.com.

The planet, called L 98-59b, marks the tiniest discovered by TESS to date.

Two other worlds orbit the same star.

NASA goes with low Solar Cycle 25 prediction “30-50% lower than cycle 24.”

NASA finally agrees with our model estimate for cycle 25 published in 2013. It’ll be interesting to see how this pans out. Leif Svalgaard predicted that cycle 25 would be higher than 24, but lower than cycle 20.

Research now underway may have found a reliable new method to predict this solar activity. The Sun’s activity rises and falls in an 11-year cycle. The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle – measured in terms of sunspot number, a standard measure of solar activity level – could be 30 to 50% lower than the most recent one. The results show that the next cycle will start in 2020 and reach its maximum in 2025.

The new research was led by Irina Kitiashvili, a researcher with the Bay Area Environmental Research Institute at NASA’s Ames Research Center, in California’s Silicon Valley. It combined observations from two NASA space missions – the Solar and Heliospheric Observatory and the Solar Dynamics Observatory – with data collected since 1976 from the ground-based National Solar Observatory.

CEI files formal complaint regarding NASA’s claim of 97% climate scientist agreement on global warming

Whatever exactly was supposed to have been agreed on, it must be difficult to show 97% support without any actual data to back it up. Is it any more than fake news?

The Competitive Enterprise Institute (CEI) petitioned NASA to remove from its website the claim that 97 percent of climate scientists agree humans are responsible for global warming, reports The Global Warming Policy Forum (GWPF).

The petition, filed under the Information Quality Act (IQA), points out the major flaws in the studies cited by NASA to substantiate its claim. 

It requests the agency remove the claim from its website and stop circulating it in agency materials.

Non-exhaust emissions from road traffic upset electric vehicle ‘clean air’ hopes

It seems switching to an EV can only scratch the surface of the clean air problems due to motor transport. Since their batteries make them heavier than fuel-burning cars they should have greater tyre wear, creating more road debris. Of course the parallel claim is that there will/would be some noticeable (presumed beneficial) effect on the climate in the long term due to lower CO2 emissions, but as we’re also told there’s little time left and sales of EVs are minimal, that doesn’t look good for climate alarmists either.

A new report released by the Air Quality Expert Group (AQEG) in the UK recommends as an immediate priority that non-exhaust emissions (NEE) are recognized as a source of ambient concentrations of airborne PM, even for vehicles with zero exhaust emissions of particles, reports Green Car Congress.

Why Phi? – exoplanetary resonances of Kepler-102

Star Kepler-102 has five known planets, lettered b,c,d,e,f. These all have short-period orbits between 5 and 28 days. Going directly to the orbit period numbers we find:
345 b = 1824.0012 d
258 c = 1824.4263 d
177 d = 1825.1709 d
113 e = 1824.4629 d
(for comparison: about 1-2 days short of 5 Earth years)

For the purposes of this post planet f (the furthest of the five from its star) is excluded, except to say that in terms of conjunctions 8 e-f = 11 d-e. Now let’s look for some resonances of the inner four planets.

Extinction Rebellion prosecutions ‘beggar belief’, says lawyer

So does the manufactured climate alarm due to a minor trace gas in the atmosphere, but this is the world we find ourselves in.

A lawyer representing hundreds of Extinction Rebellion protesters said it “beggars belief” so many of them are being prosecuted, reports the Evening Standard. 

It comes as two courtrooms are being set aside for a day each week at Westminster Magistrates’ Court for 19 weeks, to deal with Extinction Rebellion protesters arrested in mass demonstrations across the capital.

Around 35 protesters are due to appear at City of London magistrates’ court on Friday, while it is thought more than 50 will be summonsed every Friday in August.

A Sunspot from the Next Solar Cycle

.
.
The transition from solar cycle 24 to 25 is…out there somewhere. But it seems AR2744 is likely to become known as ‘the first official sunspot of Solar Cycle 25.’

Spaceweather.com

July 8, 2019: Solar Cycle 25 is coming to life. For the second time this month, a sunspot from the next solar cycle has emerged in the sun’s southern hemisphere. Numbered “AR2744”, it is inset in this magnetic map of the sun’s surface from NASA’s Solar Dynamics Observatory:

How do we know this sunspot belongs to Solar Cycle 25? Its magnetic polarity tells us so. Southern sunspots from old Solar Cycle 24 have a -/+ polarity. This sunspot is the opposite: +/-. According to Hale’s Law, sunspots switch polarities from one solar cycle to the next. AR2744 is therefore a member of Solar Cycle 25.

Solar cycles always mix together at their boundaries. Right now we are experiencing the tail end of decaying Solar Cycle 24. AR2744 shows that we are simultaneously experiencing the first stirrings of Solar Cycle 25. The transition between Solar Cycle 24 and Solar Cycle…

405 kyr Jupiter-Venus driven Earth eccentricity cycle linked to paleoclimatic variation

A recent review article on PNAS titled ‘Astronomical metronome of geological consequence’ by Linda Hinnov makes interesting reading for talkshoppers.

A Brief Retrospective
In geology, a reliable “metronome” in the geologic record with a sufficiently short repeat time would greatly enhance the resolving power of the geologic timescale. Astronomers recognized the potential importance of a dominant 405-ky cycle in Earth’s orbital eccentricity variation for supplying such a metronome (2, 3), leading geologists to turn to the stratigraphic record of astronomically forced paleoclimate change to search for this cycle. In fact, one of the first geological studies to describe 405-ky scale stratigraphic cycling was on the Triassic–Jurassic Newark Basin lacustrine strata (4, 5) recovered in the National Science Foundation-funded Newark Basin Coring Project, in which each of the prominent 60-m-thick McLaughlin cycles in the cored sequence was assigned a 412.885- ky periodicity based on a now-legacy analytical astronomical solution, BRE74/BER78 (6, 7). Since the 1990s, there have been dozens of reports for strong 405-ky scale cycles in stratigraphic sequences from around the world that appear to bear out this astronomical calculation (8).

Indian Lunar Mission Will Measure Surface Thermal Conductivity

Lift-off is scheduled for 2:51GMT on the 15th July 2019

Our friends Ned Nikolov and Karl Zeller will be keen to see the data from the Chandrayaan 2 lunar mission scheduled for take-off next week. Among many other experiments planned, the rover will be measuring surface thermal conductivity – a key factor in estimating the global lunar surface temperature.

The daily mail reports:

India’s space agency is preparing to launch its ambitious Chandrayaan-2 mission next week which is set to land near the currently unexplored south pole of the moon.

Chandrayaan-2 will blast off from the Satish Dhawan Space Center at Sriharikota on the country’s south west coast at 2.51am (10.21pm BST) on July 15.

Alan Carlin: Unilateral US Decarbonization Could Have Serious Economic Consequences

Credit: chicagotribune.com

As the energy policies of various countries sink ever further into the realms of fantasy over the imagined role of minor trace gases in the atmosphere, what will the US do – or not do?

The current unilateral US decarbonization proposals by various Democrats promoting the Green New Deal (GND) climate schemes suffer from two particularly crucial assumptions that they have made, says Alan Carlin.

One is the extremely doubtful assumption that CO2 levels determine temperatures as opposed to temperatures determining CO2 levels. The assumption being made is that it is the atmospheric CO2 level that is the critical determinant of temperatures.

If this is wrong, as I believe it is, any dollar spent on decarbonization will provide no benefits in terms of global temperatures.
