Abstract

Over the course of two decades until 2008, the solar wind became significantly weaker with a constant declining
trend in many important solar wind parameters, and solar cycle 24 being the weakest on record since the start of
the space age. Here we show that since 2008, the Sun has reversed this long-term weakening trend with a steady
increase in various solar wind proton parameters observed at 1 au. Furthermore, comparison of values from a
fitted trend to data between 2008 and 2025 show the following increases in solar wind proton parameters: speed
(~6%), density (~26%), temperature (~29%), thermal pressure (~45%), mass flux (~27%), momentum flux or
dynamic pressure (~34%), energy flux (~40%), interplanetary magnetic field magnitude (~31%), and the radial
component of the magnetic field (~33%). This has important implications on long-term solar trends, implying that
the exceptional weakness of solar cycle 24 was most likely a recent outlier and that the Sun is not entering a
modern era Maunder/Dalton-like minimum phase in its solar variation, but is instead recovering from a ~20 yr
decline. Presently, the trending average solar wind dynamic pressure of ~1.9 nPa in the current solar cycle,
however, is still lower than the recorded ~2.4 nPa at the end of the 20th century. Continuous future measurements
will reveal whether this increase will continue in upcoming solar cycles or whether these parameters will remain
stable.

Ahahahaha poor high school dropout, so convinced the con man DuByne was right about “the” GSM and consequent ice age. Not an ounce of science, of course, exactly as you expect from a high school dropout. Instead the sun could be getting more active, adding more heat to that caused by AGW.

We need a better mod for “Environment.”

Oh dear! Musk, in between making nazi salutes, has been launching low orbit satellites for his Starlink satellite internet service. But with the sun predicted to get more active satellite lifecycles will shorten. This is because more solar activity will cause the outer edges of the atmosphere to expand, slowing low earth orbit satellites and causing them to “deorbit” sooner:

SpaceX has launched thousands of satellites in recent years to build its global internet network, but now a team of researchers have found Starlink satellites are facing an unexpected threat: the Sun.

Their study found that solar storms, bursts of energy and magnetic activity from the Sun, are making Starlink satellites reenter Earth’s atmosphere sooner than expected.

This increased space weather is reducing the amount of time Starlink satellites spend in orbit, and making them fall to Earth faster.

More about the predicted increase in solar activity:

Life will get tough for satellites.
