1/5 "The 2022 WMO/#UNEP #Ozone Assessment contains the most up-to-date understanding of ozone #depletion, reflecting the thinking of hundreds of international scientific experts who contribute to its preparation and review."

2/5 Does anyone with expertise in this area know why charged particles in plasma from #solar #flares, #coronal #mass ejections (#CMEs) and even #localized #thermonuclear #bursts, i.e. #micronovae, were not considered in this report?
3/5 The recommended terms of reference of the 2022 Assessment for the Scientific Assessment Panel (SAP) was supposed to include assessment of information and research related to
solar radiation management and its potential effect on
the stratospheric ozone layer.

While it's great to see the debate over solar cycle predictions and #SunspotCycle25 feature in the @nytimes it is unfortunate that the story leaves an impression of a lack of consensus/physics-based understanding. Thread 👇🏾1/n

First, the story by @overbye nicely connects understanding Sun's magnetism with exploration of other active stars and #exoplanets, wherein stellar activity influences conditions suitable for hosting life. It describes well how solar storms create #spaceweather impacting us 2/n 
But there are many issues that are misleading or sometimes simply incorrect. It says "A new cycle of storms will begin any day now". Well, #SolarCycle25 has already begun in late 2019. An early report on this is already published. See 👇🏾3/n

Giustamente...
Il sole alterna, all'incirca ogni 11 anni, cicli di attività caratterizzati da un picco (massimo) e una valle (minimo). Le macchie solari sono il segnale per poter osservare questa periodicità. Quando ce ne sono tante si va verso un picco relativo di attività

... quando sono poche o assenti si viaggi verso un minimo. A livello energetico le variazioni per la Terra sono quasi impercettibili, tuttavia durante i massimi possono verificarsi tempeste magnetiche (flares o brillamenti) che talvolta generano disturbi nelle comunicazioni
Now, in 2020, scientists have confirmed that the Sun has just entered a new cycle, named the #SolarCycle25.
The #SolarCycle25 Prediction Panel of international experts stated that the solar minimum occurred in December 2019. However, it took nearly 10 months to calculate and confirm the minimum due to Sun’s variability.
Solar minimum is the phase in which the magnetic activity on the Sun drops significantly marked by least number of sunspots.

Interesting outcome of the voting for the strength of #solarcycle25...people think it's going to be a moderate, NOT weak cycle! What is the solar cycle prediction panel consensus? 1/n
What does our own @cessi_iiserkol solar cycle prediction indicate? How about forecasts by diverse groups from around the world employing diverse techniques? Is there consensus on how the Sun's activity would play out over next decade? 2/n
Meanwhile the @NASASun @NOAA solar cycle prediction panel has released its consensus statement. They expect a weak solar cycle 25, which matches with what we predicted based on our solar magnetic field evolution simulations back in 2018. So I agree! 3/n
