Most people don’t know that Earth’s magnetic field has a weak spot the size of the continental US hovering over South America and the southern Atlantic Ocean.
We’re safe from any effects on the ground, but our satellites aren’t so lucky: When they zip through this magnetic anomaly, they are bombarded with radiation more intense than anywhere else in orbit. There is reason to believe that this dent in the magnetic field, called the South Atlantic Anomaly, is only getting bigger.
This anomaly is far from the only unusual feature of Earth’s magnetic field.
Massive 1600 square km iceberg breaks off Antarctica

A enormous
iceberg bigger than Los Angeles or
Greater London has separated from the Amery Ice Shelf in Antarctica, the largest to do so in more than half a century herunterladen. The table
iceberg, named D-28 by scientists, broke off the shelf in east
Antarctica on September 26. It measures 1636 square kilometres (632
square miles) in area, is 210 metres (689 feet) thick and weighs a
massive 315 billion tons insta profilbild downloaden. The iceberg will now be tracked because it
poses a potential hazard for shipping. Scientists from the

The La Jolla Shores Association is answering a call for support from a Scripps Institution of Oceanography researcher in his effort to acquire machines that measure microplastics in the air people breathe.
Dimitri Deheyn, a professor at the La Jolla institute who is studying plastics pollution, led a presentation during the association’s Jan. 13 meeting on what he called a “proposal of interest to the habitants of La Jolla” and called for further monitoring of airborne microplastics.

It is now official, 2020 ends the hottest decade on record. The top takeaway is the decadal temperature chart has now become as iconic as the “Keeling Curve,” which has recorded atmospheric carbon dioxide at Mauna Loa Observatory in Hawaii since 1958, and shows a similar upward trend.
Global Decadal Average Temperature
This warmest decade was preceded by the second warmest, which in turn was preceded by the third warmest, which in turn was preceded by the fourth warmest decade, meaning the last 40 years, on average, have been the hottest on record. The pace of heat-trapping emissions from fossil fuel burning and other human activities has not yet slowed this upward trend. Quite the opposite.
