Plus: how big will the bite of the ongoing solar minimum be, compared to the last one? We’re due to find out sometime soon.
July 16, 2019: Note to astronauts: 2019 is not a good year to fly into deep space. In fact, it’s shaping up to be one of the worst of the Space Age.
The reason is, the solar cycle. One of the deepest Solar Minima of the past century is underway now. As the sun’s magnetic field weakens, cosmic rays from deep space are flooding into the solar system, posing potential health risks to astronauts.
NASA is monitoring the situation with a radiation sensor in lunar orbit. The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been circling the Moon on NASA’s Lunar Reconnaissance Orbiter spacecraft since 2009. Researchers have just published a paper in the journal Space Weather describing CRaTER’s latest findings.

Some dangerous particles come from the Sun, and some come from the deep space. The fewer particles from the Sun, the more particles from the space. I have no idea which one is preferable – probably none. Stay home.
Man-Made Global Warming Theory Takes Major Hit
Political climate models are all wrong, two new reports claim …
“New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the earth’s climate by increasing cloud cover, causing an ‘umbrella effect,’” the Japanese scientists concluded, noting that this natural phenomenon “has never been considered in climate predictions.”
Here is a quote from professor Masayuki Hyodo, the lead researcher on the Japanese report …
“This study provides an opportunity to rethink the impact of clouds on climate. When galactic cosmic rays increase, so do low clouds, and when cosmic rays decrease clouds do as well, so climate warming may be caused by an opposite-umbrella effect. The umbrella effect caused by galactic cosmic rays is important when thinking about current global warming as well as the warm period of the medieval era.”
According to Hyodo, the politically driven climate models – including the United Nations’ Intergovernmental Panel on Climate Change (IPCC) – fail to take into account the umbrella effect in their calculations.

Intensified East Asian winter monsoon during the last geomagnetic reversal transition

Abstract:
The strength of Earth’s magnetic dipole field controls galactic cosmic ray (GCR) flux, and GCR-induced cloud formation can affect climate. Here, we provide the first evidence of the GCR-induced cloud effect on the East-Asian monsoon during the last geomagnetic reversal transition. Bicentennial-resolution monsoon records from the Chinese Loess Plateau revealed that the summer monsoon (SM) was affected by millennial-scale climate events that occurred before and after the reversal, and that the winter monsoon (WM) intensified independently of SM variations; dust accumulation rates increased, coinciding with a cooling event in Osaka Bay. The WM intensification event lasted about 5000 years across an SM peak, during which the Earth’s magnetic dipole field weakened to <25% of its present strength and the GCR flux increased by more than 50%. Thus, the WM intensification likely resulted from the increased land–ocean temperature gradient originating with the strong Siberian High that resulted from the umbrella effect of increased low-cloud cover through an increase in GCR flux.

COSMIC RAY UPDATE–NEW RESULTS FROM THE MOON:
Note to astronauts: 2019 is not a good year to fly into deep space. In fact, it’s shaping up to be one of the worst of the Space Age. One of the deepest Solar Minima of the past century is underway now. As the sun’s magnetic field weakens, cosmic rays from deep space are flooding into the solar system, posing potential health risks to space travelers.
NASA is monitoring the situation with a radiation sensor in lunar orbit. The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) has been circling the Moon on NASA’s Lunar Reconnaissance Orbiter spacecraft since 2009. Researchers have just published a paper in the journal Space Weather describing CRaTER’s latest findings.
Plain Language Summary
We report measurements of increasing intensities of galactic cosmic ray protons and helium ions from 2015 to the end of 2018. The overall decrease in solar activity in this period has led to an increased flux of energetic particles, to levels that are approaching those observed during the previous solar minimum in 2009/2010, which was the deepest minimum of the Space Age. The data have implications for human exploration of deep space and may provide useful benchmarks for models of cosmic ray fluxes as a function of solar modulation.

The latest data from CRaTER show cosmic ray fluxes almost doubling since 2015 (from spaceweather.com).
WILL SOLAR MINIMUM LEAD TO GLOBAL COOLING?
Date: 20/07/19 Daily Express
Cosmic rays are continuously getting stronger and that could mean Earth should brace itself for a deep solar minimum, scientists have warned.
