Deep in the ocean’s twilight zone, swarms of ravenous single-celled organisms may be altering Earth’s carbon cycle in ways scientists never expected, according to a new study from Florida State University researchers.
In the area 100 to 1,000 meters below the ocean’s surface — dubbed the twilight zone because of its largely impenetrable darkness — scientists found that tiny organisms called phaeodarians are consuming sinking, carbon-rich particles before they settle on the seabed, where they would otherwise be stored and sequestered from the atmosphere for millennia.
This discovery, researchers suggest, could indicate the need for a re-evaluation of how carbon circulates throughout the ocean, and a new appraisal of the role these microorganisms might play in Earth’s shifting climate.
The findings were published in the journal Limnology and Oceanography.

The sun has been blank for 21 days–3 whole weeks without sunspots. To find an equal number of consecutive spotless days in the historical record, you have to go back to July-August 2009 when the sun was emerging from an unusually deep solar minimum. Solar minimum, welcome back!

While NBC News might think that 68,000 page views per month is impressive, in comparison to our regular daily traffic on WUWT, it pales in comparison. For example, here is a screencap from my WordPress dashboard from yesterday, July 16th, which was a fairly typical summer day for WUWT. Note that it shows 92,467 page views in one day.
What’s most interesting is that while there’s been a slow, almost imperceptible increase in the phrase “climate change”, the search phrase “global warming” is getting far less use than it did when data was first collected, back in 2004. Right now, both “climate change”, and “global warming” have low interests.

Last year the United States had the largest decline in CO2 emissions *in the entire world* for the 9th time this century.
From the June 2018 BP Statistical Review of Global Energy (67th edition) here are some details on C02 emissions in 2017: (…)

There may be more than a quadrillion tons of diamond hidden in the Earth’s interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate the precious minerals are buried more than 100 miles below the surface, far deeper than any drilling expedition has ever reached.
The ultradeep cache may be scattered within cratonic roots — the oldest and most immovable sections of rock that lie beneath the center of most continental tectonic plates. Shaped like inverted mountains, cratons can stretch as deep as 200 miles through the Earth’s crust and into its mantle; geologists refer to their deepest sections as “roots.”
In the new study, scientists estimate that cratonic roots may contain 1 to 2 percent diamond. Considering the total volume of cratonic roots in the Earth, the team figures that about a quadrillion (1016) tons of diamond are scattered within these ancient rocks, 90 to 150 miles below the surface.

Sometimes a chance comment sets off a whole chain of investigation. Somewhere recently, in passing I noted the idea of the slope of the temperature gradient across the Pacific along the Equator. So I decided to take a look at it. Here is the area that I examined.
I’ve written about this temperature gradient before, in a post called The Tao of El Nino. If you take time to read that post, this one will make more sense. …

L ’hydrogène, un gaz peu abondant…
L’ hydrogène n’est présent qu’à concurrence de 1 ppm ( = une ‘partie par million’, soit 0,0001%) dans l’atmosphère : autant dire que c’est presque rien. D’où vient-il ? Peut-on en produire de grandes quantités à partir de ressources naturelles (géologie) ou artificielles (chimie) ? Autant de questions que de plus en plus d’industriels, de scientifiques, de politiques et de citoyens (?) se posent pour faire face à ce qu’il est convenu d’appeler la transition énergétique tant à l’ordre du jour, à raison ou à tort, là n’est pas l’objet de cet article. Comme nous le verrons par la suite, l’exploitation directe de l’hydrogène naturel n’est pas encore rentable et il faudra sans doute le produire à partir d’une autre source d’énergie, car il n’est pas lui-même une source d’énergie, mais au contraire un simple vecteur d’énergie.A l’heure actuelle il n’est donc pas exploité à une échelle suffisante en raison des contraintes géologiques et économiques, et il faut le synthétiser . C’est ce que réalise aujourd’hui l’industrie principalement en vue de la fabrication de l’ammoniac pour les engrais ou des plastiques.

Unearthed new evidence (Mangerud and Svendsen, 2018) reveals that during the Early Holocene, when CO2 concentrations hovered around 260 ppm, “warmth-demanding species” were living in locations 1,000 km farther north of where they exist today in Arctic Svalbard, indicating that summer temperatures must have been about “6°C warmer than at present”.
Proxy evidence from two other new papers suggests Svalbard’s Hinlopen Strait may have reached about 5 – 9°C warmer than 1955-2012 during the Early Holocene (Bartels et al., 2018), and Greenland may have been “4.0 to 7.0 °C warmer than modern [1952-2014]” between 10,000 and 8,000 years ago according to evidence found in rock formations at the bottom of ancient lakes (McFarlin et al., 2018).
In these 3 new papers, none of the scientists connect the “pronounced” and “exceptional” Early Holocene warmth to CO2 concentrations.

Hurricane threat to East Coast due to natural factors
First at his most recent Saturday Summary, the 40-year meteorologist first warns that in-close developing hurricanes of the sort seen in the 1930s are a risk to the US East Coast this year, due the current Atlantic temperature pattern. The reason has nothing to do with CO2 in the atmosphere, but because of natural sea surface temperature cycles.
Sea surface temperatures see “pretty dramatic turnaround”
by Dr. Duane Thresher, April 26, 2017 in PrincipiaScientificIntern.
Climate model/proxy research that does not show global warming will not get published or funded because of:
- Non-publication of negative results (no global warming found)
- Fearful self-censorship
- Conflict of interest (a need to get results, regardless of validity, that further careers)
- Corrupt fanatical unqualified “working” scientists
- Censorship by established scientists in a fundamentally-flawed peer review process (peers are all-too-human competitors)
- Corruption of climate science overall

Diesel cars may still be the most sensible option for many families who drive long distances, the transport secretary Chris Grayling said yesterday.
Despite a pledge to see the end of petrol and diesel vehicles on UK roads by 2040, Mr Grayling said new diesels were not destined for the scrapheap just yet.
He said: ‘If you are doing long distances on the motorway, maybe the new generation of diesel engines are the right option for now.

The Climategate emails expose to our view a world that was previously hidden from virtually everyone.
This formerly hidden world was made up of a very few players. But they controlled those critical Intergovernmental Panel on Climate Change (IPCC) processes involv- ing the temperature records from the past, and the official interpretation of cur- rent temperature data. They exerted previously unrecognized influence on the “peer review” process for papers seeking publication in the officially recognised climate science literature from which the IPCC was supposed to rely exclusively in order to draw its conclusions.

L’ Anthropocène est la dernière création marketing d’un géologue. Avec un certain succès médiatique alors que les scientifiques s’y opposent fermement. Pourquoi ?
by Marc Morano, July 13, 2018 in ClimateDepot
The ‘average’ world temperature for June 2018 was +0.21 deg C above the 1981 – 2010 mean. That represented a decline of about 0.65 deg C from the all-time high of this 39-year record, which was reached in early 2016. The 0.65 deg C decline represented more than 75% of the amount by which the average temperature had exceeded the 1981 – 2010 mean at the highest point. Suddenly the fact that some large number of “all-time highs” was being set at the end of June does not seem very significant.”

Arctic sea ice volume melt rates have started to slow, with ice volume 4th highest since 2003.
Temperatures near the pole have been below normal almost every day this summer.
