At Klimanachrichten, Dr. Ludger Laurenz looks how solar influence on rainfall in Germany.

Precipitation patterns linked to the 22-year Hale cycle. 

While droughts and periods of heavy precipitation in Germany are often blamed on CO2 climate change by the media and pseudo-experts, Laurenz sees a clear link to the 22-year solar Hale cycle. This can be detected in many historical weather data series.

To search for the solar influence on the annual precipitation sum, he used the data from the DWD dating back to 1903.

Finding: “Different precipitation trends are repeated every 22 years. This indicates solar influence.”

According to Laurenz, “The exceptionally high level of precipitation totals in the last year and the first two months of 2024 is very likely due to solar influence.”

Moreover, he found: “The evidence of solar influence on precipitation totals is even better if periods over the turn of the year are selected instead of the classic annual period from January to December, such as the 12-month period from July to June of the following year or the winter half-year. The solar influence on the precipitation sum is much stronger in the winter half-year than in the summer half-year.”

The solar magnetic cycle (Hale cycle) lasts approximately 22 years and can be detected in solar physical measurement data (Chapman et al. 2021) and the search for solar influence is based on Chapman’s formulations.

With the change from one Hale cycle to the next, the sun starts a new program of activity within a few weeks that repeats itself in the same pattern approximately every 22 years. Every single month and every single year of the 22-year Hale cycle is characterized by a specific solar activity pattern that affects the Earth’s atmosphere and creates weather trends.

Ms. Veretenenko’s latest publication from the Loffle Institute in Saint Petersburg has described the mechanism of the transformation of varying solar activity via the stratosphere to the troposphere and thus our weather.

Using the start years of the Hale cycles, it is easy to prove solar influence in historical weather data, Larenz shows.

To do this, the weather data from the same approx. 22-year cycle phases, starting with the respective start years of the Hale cycles, are stacked on top of each other. The result:

Every 22 years, extremely high and low annual precipitation totals accumulate in the same phases of the 22-year Hale cycle.

Drought conditions in Northern China

Is lithium more of a problem than a solution? Climate worriers wouldn’t like that as it goes against their visions of a battery-filled future.

The world needs to better manage its freshwater resources, says AFP (via Phys.org), but thirsty new technologies touted as solutions could lead to “serious problems” if left unchecked, a UN report warned Friday.

Roughly half of the planet’s population is facing grave water shortages, with climate change-linked droughts affecting more than 1.4 billion people between 2002 and 2021, the report for the UN cultural agency UNESCO said.

As of 2022, more than 2 billion people were without access to safely managed drinking water, while 3.5 billion people lacked access to decent toilets, it added.
. . .
The report, titled “Water for prosperity and peace”, called for more water education, data collection and investment to address the crisis.
. . .
It also highlighted the limits of new computer-led solutions.

“An array of technologies is available to improve both water supply, water use efficiency and the quality and extension of” sanitation services, it said.

But “several rapidly emerging technologies are highly water-intensive and, if left unchecked, could lead to serious problems in the near future.”

Artificial intelligence (AI) had “the potential to enhance (river) basin management, emergency response, and the operation and maintenance of water supply and wastewater treatment plants,” said the report.

But “AI and related technologies require large volumes of water for computer cooling systems, in addition to the (often water-intensive) energy required to power the equipment.”

Flawed solutions

While climate change is projected to intensify patterns of record rainfall and drought in coming years, solutions to tackle that problem were also using up too much water, it added.

One such technique, called carbon capture and storage, siphons off CO2 from the exhaust of fossil fuel-fired power plants and heavy industry such as steel and cement factories in a bid to reduce planet-heating carbon pollution. [Talkshop comment – carbon dioxide at trace gas level has never polluted anything, and never will].

But “carbon capture and storage systems… are extremely energy- and water-intensive,” the report said.

Energy production accounts for between 10 and 15 percent of global water withdrawals, both to extract fossil fuels and cool thermal and nuclear power stations, it said.

While wind, solar and geothermal energy systems are more water-efficient, they still require lithium batteries for power storage. [Talkshop comment – so do electric road vehicles, plus some other modes of transport].

Yet the extraction of lithium and other critical minerals for solar panels “is usually highly water-intensive, with significant risks to water quality” especially groundwater, ecosystems and local populations, the report said.
