#cooling
A top polar scientist interviewed by the Russian Academy of Sciences says we need to prepare for serious global cooling, to begin by 2030-2035. Cites studies of Lake Baikal and historic climate epochs.
People's Voice here reports: "One of the world's top Arctic scientist's has spoken out to debunk the 'climate crisis' narrative" and #warns the #public that "the #Earth is actually about to enter a period of 'global #cooling.'"
According to leading polar scientist Andrey Fedotov of the Siberian Branch of the Russian Academy of Sciences (RAS), "the warming is about to end" and "The Earth is about to enter an 'ice age.'"
Cooling starts in 2030
The period of "unfavorable cold" will begin around 2030. Fedotov issued the warning in a statement published by the RAS, the country's leading scientific institution.
Fedotov said the warming is about to end and the cause is not humans. The Russian scientist says the cooling will be brought on by solar activity.

OpenFan – A DIY Open-Source PC Fan Controller for up to 10 Individually Controlled Fans
This is quite a nice project, but is not an off the shelf solution. Most folks may get by quite well with the 4 or so fans that a PC can already control, but if you need this level of granular control for up to 10 fans, this project may be for you.
It is also open-source hardware, and a lot of thought went into how it can easily connect inside the case. The video he published does explain it very well.
I see the board has place for external temperature sensors to be added, which he does not seem to be using yet, and of course, the other big thing is the automation by 3rd party software to manage it.
That all said, the project appears to have been published only about 4 days back, so there may be a lot more contributions that will still be made to this project.

" #Antarctica is #cooling. The data confirm it.
Temperatures at the bottom of the world have routinely broken all-time records in recent times.
Antarctica endured its coldest-ever ‘coreless winter’ (April-Sept) in 2021, then shivered through practically all of 2022, posting colder-than-average month after colder-than-average month, including the coldest November since 1987 and the latest -60C (-76F) on record — with the year culminating in the South Pole Station averaging just -49.5C (-51.7F); -0.4C below the norm.
The historic chill has spilled into 2023, too.
Back in March, the Antarctic continent suffered its coldest ever reading so early into a year; in July it logged Earth’s lowest temperature since 2017; and now, in mid-August, it’s breaking multiple all-time cold records at stations across the continent."

Coolero is an Open-Source App to Monitor and Control a Computer’s Cooling Devices on Linux
When it comes to Linux, we do not get official software support from brands like NZXT, Corsair, MSI, ASUS, etc., to manage hardware components on PC.
Coolero is a front-end that uses libraries like liquidctl and a few others to control cooling devices, mostly AIOs, fan hub/controllers, along with PSUs and some RGB lighting support. Coolero has been making good progress with NZXT and Corsair devices so far, but it is still a work in progress. Its functionality is not just for monitoring, as it can also control a number of essentials such as adjusting fan profiles and RGB light profiles, multiple versions of a device, etc. It supports most of the devices liquidctl supports.
So before buying any new high-end device to use on Linux, you may well want to have a look at their GitLab project page to see what devices Coolero already supports.

University of California Professor Develops Technology That Cools People Down – Without Electricity or AC
A UCLA scientist reasoned that if a certain spectrum of warming rays is radiated out to the atmosphere during the day, it would cool whatever it left, potentially offering an alternative to traditional air conditioning.
An estimated 7% of global greenhouse gas emissions are generated through cooling systems, both for homes and transport, but as global temperatures continue to climb, the use of cooling systems for homes and businesses is expected to triple over the coming years.
SkyCool’s radiative panels can absorb all the heat-producing light from the sun, and rather than sending it back into the swirling cauldron of gasses that are heating the planet, expels it out into space.
If placed on the hood of a car, the film would not only reflect any light from the sun, but radiate away some of the heat from the engine; if placed above where water pipes run through a building, it would cool the water therein, reducing the load on air-conditioning systems.

"As a wind catcher requires no electricity to power it, it is both a cost-efficient and green form of #cooling. With conventional mechanical air conditioning already accounting for a fifth of total electricity consumption globally, ancient alternatives like the wind catcher are becoming an increasingly appealing option.
There are two main forces that drive the air through and down into the structures: the incoming wind and the change in buoyancy of air depending on temperature – with warmer air tending to rise above cooler, denser air. First, as air is caught by the opening of a wind catcher, it is funneled down to the dwelling below, depositing any sand or debris at the foot of the tower. Then the air flows throughout the interior of the building, sometimes over subterranean pools of water for further cooling. Eventually, warmed air will rise and leave the building through another tower or opening, aided by the pressure within the building.
The shape of the tower, alongside factors like the layout of the house, the direction the tower is facing, how many openings it has, its configuration of fixed internal blades, canals and height are all finely tuned to improve the tower's ability to draw wind down into the dwellings below."...
