Now from what we know, from what the current data is providing, we could be entering a zone where the cloud is denser. We could also be entering a zone of our galaxy where the space is denser. As the bowshock has turned into a bow wave, as the heliosphere is weakened, as more cosmic rays and interstellar dust are getting through to us, it is far from insane to think that we might be heading for a new ice age or at the very least, a mini ice age. It becomes more and more factual and this does affect us all.
"The space factors which inﬂuence Earth’s climate most, however, are cosmic rays (CR) and space dust, which inﬂuence the creation of clouds and therefore control the total energy transferred from the Sun to the Earth’s atmosphere."
"Over this period there is a striking qualitative correlation between cold and warm climate periods and high and low levels of galactic CR intensity, correspondingly (low and high solar activity)"
"Cosmic rays play a key role in the formation of thunderstorms and lightnings".
"Above we considered space factors acted on the Earth’s Climate mainly through CR in frame of scales not bigger than one thousand years. In Fig. 9 are shown data on planetary surface temperature changing during the last 520 million years, caused to the moving of the Solar system around the centre of our Galaxy and crossing galactic arms with bigger probability to interact with molecular-dust clouds and supernova remnants (with bigger intensity of CR and higher density of space dust, which both lead to increasing of cloudiness and decreasing of planetary surface temperature)"
The UN Braces for Stormy Space Weather
Into this void stepped the United Nations. In 1958, the General Assembly "recognizing the common interest of mankind in furthering the peaceful use of outer space ... and desiring to avoid the extension of present national rivalries into this new field...." established the Committee on the Peaceful Uses of Outer Space (COPUOS). COPUOS became a forum for development of laws and treaties governing space-related activities. Moreover, it set the stage for international cooperation on problems that no one nation could handle alone. .
At each annual meeting in Vienna, Austria, COPUOS members confer about these issues, which present some key challenge or peril to the whole planet.
Space weather might play a role in Earth’s climate, too. For example, the Maunder minimum, a 70-year period almost devoid of sunspots in the late 17th to early 18th century, coincided with prolonged, very cold winters in the northern hemisphere.
Today, tomorrow, next week, next year… sometime in the coming decades… our planet could once again be hit by an intense volley of Galactic cosmic rays. It will come cloaked and hidden from us, until the very moment it strikes. We live on the edge of a galactic volcano. Knowing neither the time, the magnitude, nor the severity of the next eruption or its impact on our environment, we stand unprepared to deal with this event, much less anticipate its arrival.
In just one day, a major Galactic superwave event would inject into the geomagnetic field a particle energy equivalent to 1000 one-megaton hydrogen bomb explosions (1025 ergs). At this rate, the energy delivered to the belts after one year would exceed 30,000 times the energy received from the most powerful solar cosmic ray storms observed in modern times.
Is the Local Interstellar Cloud affecting us in any way?
