The West Is A Dystopian Wasteland Of Moral Degeneracy

The moral degeneracy of this civilization looks like living lives of relative comfort built on the backs of workers in the global south whose labor and resources are extracted from their nations at profoundly exploitative rates, while raining military explosives on impoverished populations who dare to disobey the dictates of our government, day after day, year after year, decade after decade, and acting like this is all fine and normal.

Being born into western civilization is like waking up in the middle of a massive lynch mob.

Speech by President Lula at the opening of the 37th African Union Summit

Our paths will meet again at the G20 Summit, in Rio de Janeiro, and at COP 30, in Belém. The presence of the African Union as a full member of the G20 will be of great value—but including more countries from the continent as full members is still also necessary. We have common agendas to defend.

It is unacceptable that a world capable of generating wealth in the order of USD 100 trillion dollars per year still harbors the hunger of more than 735 million people. We are creating the Global Alliance against Hunger at the G20 so as to promote a set of public policies and mobilize resources to finance them.

Around 60 countries—many of them in Africa—are coming close to financial insolvency, allocating more resources to paying external debt than to education or health. This reflects the obsolete nature of financial institutions such as the IMF and the World Bank, which often worsen crises that they should be resolving.

Lula meets African presidents, speaks of strong Global South

On a visit to Ethiopia, Brazilian President Luís Inácio Lula da Silva said Sunday (Feb. 18) that Brazil has a historical debt to Africa and advocated that the countries of the Global South step up their relations. He traveled to attend the 37th African Union Summit, which brought together heads of state and members of government from the 54 countries of the African continent. As a guest, President Lula took the opportunity to hold meetings and bolster bilateral ties.

Linksregierungen in Lateinamerika fordern globalen Norden heraus

New York. Die links-gerichteten Präsident:innen aus Lateinamerika haben bei der 78. Vollversammlung der Vereinten Nationen grundlegende Veränderungen der globalen wirtschaftlichen und politischen Ordnung gefordert. Sie übten scharfe Kritik am internationalen Finanzsystem und am Krieg in der Ukraine, die in ihren Augen den Kampf gegen Armut, Ungleichheit und Klimawandel verhindern.

Scientists link California droughts, floods to distinctive atmospheric waves

(6.4.2017) Wavenumber-5 consists of five pairs of alternating high- and low-pressure features that encircle the globe about six miles (10 kilometers) above the ground. It is a type of atmospheric phenomenon known as a Rossby wave, a very large-scale planetary wave that can have strong impacts on local weather systems by moving heat and moisture between the tropics and higher latitudes as well as between oceanic and inland areas and by influencing where storms occur.

The slow-moving Rossby waves at times become almost stationary. When they do, the result can be persistent weather patterns that often lead to droughts, floods, and heat waves.

Planetary waves, first found on Earth, are discovered on Sun

(27.3.2017) for a brief period, from 2011 to 2014, scientists had the unprecedented opportunity to see the Sun‘s entire atmosphere at once. During that time, observations from NASA‘s Solar Dynamics Observatory (SDO), which sits between the Sun and Earth, were supplemented by measurements from NASA‘s Solar TErrestrial RElations Observatory (STEREO) mission, which included two spacecraft orbiting the Sun. Collectively, the three observatories provided a 360-degree view of the Sun until contact was lost with one of the STEREO spacecraft in 2014. McIntosh and his co-authors mined the data collected during the window of full solar coverage to see if the large-scale wave patterns might emerge.

„By combining the data from all three satellites we can see the entire Sun, and that‘s important for studies like this because you want the measurements to all be at the same time,“ said Dean Pesnell, SDO project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. „They’re pushing the boundary of how we use solar data to understand the interior of the Sun and where the magnetic field of the Sun comes from.“

Study: Hole in ionosphere is caused by sudden stratospheric warming

(6.8.2018) Geospace research has long established that certain changes in the atmosphere are caused by the sun’s radiation, through mechanisms including solar wind, geomagnetic storms, and solar flares. (…)

One of the more scientifically interesting large-scale atmospheric events is called a sudden stratospheric warming (SSW), in which enormous waves in the troposphere — the lowermost layer of the atmosphere in which we live — propagate upward into the stratosphere. These planetary waves are generated by air moving over geological structures such as large mountain ranges; once in the stratosphere, they interact with the polar jet streams.

A Mystery in the Mesosphere

(15.8.2018) Harvey and her colleagues are still working to understand how the extra water got up there. One possibility involves planetary wave activity in the southern hemisphere which can, ironically, boost the upwelling of water vapor tens of thousands of miles away in the north. The phenomenon could also be linked to solar minimum, now underway. It is notable that the coldest and wettest years in the mesosphere prior to 2018 were 2008-2009–the previous minimum of the 11-year solar cycle.

New study explains Antarctica’s coldest temperatures

(25.6.2018) That preliminary study has been revised with new data showing that the coldest sites actually reach -98 degrees Celsius (-144 degrees Fahrenheit). The temperatures are observed during the southern polar night, mostly during July and August.

When the researchers first announced they had found the coldest temperatures on Earth five years ago, they determined that persistent clear skies and light winds are required for temperatures to dip this low. But the new study adds a twist to the story: Not only are clear skies necessary, but the air must also be extremely dry, because water vapor blocks the loss of heat from the snow surface.

Coldest temperature ever recorded makes Earth „almost like another planet“

Nearly 15 degrees colder than the previous record-breaking coldest temperature, which was -128 degrees in 1983 near the South Pole, the temperature in Antarctica dropped to -144 degrees Fahrenheit.

Temperatures this low make Antarctica „almost like another planet,“ says lead researcher Ted Scambos at the National Snow and Ice Data Center in Boulder, Colorado, quoted in Forbes.

Taking just a few breaths of air this cold would kill you.

Watching the Sun for Space Weather

(10.8.2018) “Space weather occasionally occurs in tandem with extreme terrestrial weather,” according to scientists from NCEI, Cooperative Institute for Research in Environmental Sciences (CIRES), and other institutions in an open access Space Weather journal article. “When it does, the struggle to mitigate the impacts to life and property can be dramatically intensified. This one-two punch landed on the socioeconomically and technologically diverse communities of the Caribbean islands during the September 2017 hurricane season.”
