I hate to say this, but x-rays are not only NOT streams of electrons, they're not even cosmic rays.

Gamma ray burst is a source of a particular type of cosmic rays.
Cosmic rays are high-energy particles arriving at Earth from sources that lie outside it. What exactly is "high energy" in this definition is not well defined. Practically any stable particle can be a cosmic ray. Thus you may have photons (gamma rays), electrons, protons, nuclei, neutrinos...

NASA-Funded Mission Studies the Sun in Soft X-Rays
...
The soft X-ray detector flew first on June 23, 2012, and again on October 21, 2013.
During both flights, there were only a few complex active regions on the sun's surface – indeed, very few during the 2012 flight. Yet, in both flights the detector saw 1000 times more soft X-rays than had been seen by another experiment in 2009. Even a slight extra amount of solar activity in the form of these active regions, led to substantially more output in the soft X-ray wavelengths.
Wavelengths of light correlate to particular temperatures of material on the sun, and this abundance of soft X-rays points to clouds of hot – 5 to 10 million degrees – gases above the active regions that wasn't present during the 2009 measurements when there were no active regions on the sun. That kind of information makes it clear that different heating mechanisms occur on the quiet sun and active regions, opening the door to determining the differences. One theory for the source of this mysterious heating is that numerous tiny explosions called nanoflares are constantly erupting on the sun. Nanoflares are too small to be seen by our telescopes, but powerfully energetic nonetheless. The soft X-rays might well be a result of nanoflares, thus giving us a way of investigating them.
The new soft X-ray data differed from previous data studies in another respect as well. By parsing out the amounts of each individual wavelength of light gathered, the team could identify what elements were present in the corona. Typically, the abundance of some of these atoms in the corona is greater than at the sun's surface. But not so in these recent observations. The mix of material in the corona was more similar to the mix seen at the solar surface, suggesting that some material from the surface was somehow rising up higher into the atmosphere.
"The difference we see in the abundances of the elements compared to previous studies suggest there may be a link between the heating mechanism and the coronal composition," said Caspi.
Untangling the elements present on the sun's surface and in its atmosphere during different events on the sun could offer another set of tools for interpreting what heats the corona.
Discovering that the soft X-ray emission was brighter than supposed has effects for understanding space weather events near Earth as well. Different wavelengths of light from the sun penetrate to different layers of Earth's atmosphere, causing different effects.
"The solar soft X-rays are deposited lower in Earth's atmosphere than the sun's extreme ultraviolet radiation," says Tom Woods, a co-author on the paper and the principal investigator for this experiment at the University of Colorado in Boulder. "The soft X-rays cause almost instantaneous changes in the ionosphere that can disturb radio communications and the accuracy of GPS navigation systems."

Er, yes.
As it takes accelerated electrons to produce the effect of x-ray (magnetic waves are a cause)

It takes ENERGY to produce EM waves. Electron bombardment is used to produce that energy because electrons, being negatively charged, can be easily accelerated using present technology.
I'm sorry, but you really need to brush up on your physics...

ESA sees stardust storms heading for Solar System
PRESS RELEASE
Date Released: Monday, August 18, 2003
Source: Artemis Society
Until ten years ago, most astronomers did not believe stardust could enter our Solar System. Then ESA's Ulysses spaceprobe discovered minute stardust particles leaking through the Sun's magnetic shield, into the realm of Earth and the other planets. Now, the same spaceprobe has shown that a flood of dusty particles is heading our way.
...
What is surprising in this new Ulysses discovery is that the amount of stardust has continued to increase even after the solar activity calmed down and the magnetic field resumed its ordered shape in 2001.
Scientists believe that this is due to the way in which the polarity changed during solar maximum. Instead of reversing completely, flipping north to south, the Sun's magnetic poles have only rotated at halfway and are now more or less lying sideways along the Sun's equator. This weaker configuration of the magnetic shield is letting in two to three times more stardust than at the end of the 1990s. Moreover, this influx could increase by as much as ten times until the end of the current solar cycle in 2012.

Abstract
...
Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the 'near' future and might have a drastic influence on terrestrial climate in the next 10,000 years.

Space radiation hits record high
By David Shiga
Now, the influx of galactic cosmic rays into our solar system has reached a record high. Measurements by NASA's Advanced Composition Explorer (ACE) spacecraft indicate that cosmic rays are 19 per cent more abundant than any previous level seen since space flight began a half century ago."The space era has so far experienced a time of relatively low cosmic ray activity," says Richard Mewaldt of Caltech, who is a member of the ACE team. "We may now be returning to levels typical of past centuries."

And I'm sorry but you really need to brush up on your reading skills, as it seems you want to argue for the sake of it. Initially I SAID Accelerated Electrons hitting a target (unless we're being intentionally ignorant, there IS implied energy there)
And what is your point with it taking energy anyway, there IS no greater (for our purposes) source of energy available to us THAN the Sun which IS what is bombarding our planet with Cosmic Radiation....
I don't understand your unnecessary cyclical argument. Turn the mirror inward...

I know that the Moon is a source of Gamma as cosmic radiation is somehow catalyzed by the Moons surface and goes gamma.

As stated by others, cosmic ray intensity is strongly correlated with solar activity (11 years cycles). If cosmic rays had an effect on global temperature it would be clearly visible.
originally posted by: moebius
The amount of radiation required to increase temperature directly would be deadly.
originally posted by: moebius
There is the idea that the primary effect would be not heating but cloud formation, means with increasing radiation the amount of clouds would increase, reducing global temperature. But this is not observed either.

You also said, and continue to maintain, that x-rays ARE electrons, which is not true. You can get x-rays from other sources. Hell, you can even get them more than one way from electrons.

Do you not believe the spike in CO2 levels we are observing are NOT mostly from human activity? Does CO2 NOT play an important role in our climate?
Also, we have terraformed this planet and continue to do so.

That is simply not true. You may be referring to the solar wind, which is made up of such components.
We know today that galactic cosmic rays are atom fragments such as protons (positively charged particles), electrons (negatively charged particles) and atomic nuclei. While we know now they can be created in supernovas, there may be other sources available for cosmic ray creation. It also isn't clear exactly how supernovas are able to make these cosmic rays so fast.
