Japan, like much of the world this NH summer, is experiencing unseasonably cloudy weather and cool temperatures — Tokyo has seen fewer than three hours of sunshine a day over the past 20 days, the lowest number since Japan’s Meteorological Agency (JMA) started collecting data in 1961.
Gloomy skies and unusually low temperatures have decimated agriculture across much of Japan this summer. Many vegetables have posted double-digit price gains, with cucumber’s skyrocketing 70%, according to the Ministry of Agriculture, Forestry and Fisheries.
While Japan does expect a rainy season between late June and early July, it has usually finished by now.
The two months of intense heat and humidity that normally follow are still nowhere to be seen, with the JMA’s latest forecast revealing they’ll be at least another 10 days of this cool and damp weather, further disrupting the nation’s growing season.
COSMIC RAYS, CLOUD SEEDING AND GLOBAL COOLING
Galactic Cosmic Rays are a mixture of high-energy photons and sub-atomic particles accelerated toward Earth by supernova explosions and other violent events in the cosmos. Solar Cosmic Rays are the same, though their source is the sun.
Cosmic rays hitting Earth’s atmosphere create aerosols which, in turn, seed clouds — making cosmic rays an important player in our weather and climate (Svensmark, et al).
During solar minimum, like the one we’re entering now, the sun’s magnetic field weakens and the outward pressure of the solar wind decreases — this allows more cosmic rays to penetrate our planet’s atmosphere as the weakened solar wind no longer deflects them away.
With this being a Grand Solar Minimum we’re entering, Cosmic Rays should be off the charts — and that’s exactly what researchers are seeing:
Along with an uptick in localised precipitation, increased cloud cover has another major implication for our climate:
“Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming, or global cooling,” — Roy W. Spencer PhD.
The upshot of our descent into this next Grand Solar Minimum will be a cooling of the planet.
And, since the recent record El Niño’s peak in 2016, global average temperatures have in fact been nosediving. This cooling trend will likely accelerate further over the coming months, as the effects of the super El Niño continue to wane and eventually dissipate — expected sometime in July/August 2019.
The cold times are returning, in line with historically low solar output.
Even NASA agrees, in part at least, with their solar cycle 25 forecast:
