The problem is, as the authors note in their new paper, the shield is weakening: “Over the last decade, the solar wind has exhibited low densities and magnetic field strengths, representing anomalous states that have never been observed during the Space Age. As a result of this remarkably weak solar activity, we have also observed the highest fluxes of cosmic rays.”
Back in 2014, Schwadron et al used a leading model of solar activity to predict how bad cosmic rays would become during the next Solar Minimum, now expected in 2019-2020. “Our previous work suggested a ∼ 20% increase of dose rates from one solar minimum to the next,” says Schwadron. “In fact, we now see that actual dose rates observed by CRaTER in the last 4 years exceed the predictions by ∼ 10%, showing that the radiation environment is worsening even more rapidly than we expected.”

At least this mysterious source close to our Solar System was first detected in 2008, and since then it has continued to increase the amount of cosmic rays it keeps sending towards our Solar system.
Source?
That "anomalous/mysterious source" has been sending enough cosmic rays with enough energy to reach Earth's surface since at least 2008, and the amount of cosmic rays it keeps sending our way keeps increasing.

Mysterious Source of High-Energy Cosmic Radiation Discovered
WASHINGTON -- Scientists announced Wednesday the discovery of a previously unidentified nearby source of high-energy cosmic rays. The finding was made with a NASA-funded balloon-borne instrument high over Antarctica.
Researchers from the Advanced Thin Ionization Calorimeter (ATIC) collaboration, led by scientists at Louisiana State University, Baton Rouge, published the results in the Nov. 20 issue of the journal Nature. The new results show an unexpected surplus of cosmic ray electrons at very high energy -- 300-800 billion electron volts -- that must come from a previously unidentified source or from the annihilation of very exotic theoretical particles used to explain dark matter.
"This electron excess cannot be explained by the standard model of cosmic ray origin," said John P. Wefel, ATIC project principal investigator and a professor at Louisiana State. "There must be another source relatively near us that is producing these additional particles."
According to the research, this source would need to be within about 3,000 light years of the sun. It could be an exotic object such as a pulsar, mini-quasar, supernova remnant or an intermediate mass black hole.

The two known sources of X-ray emission are the solar wind, the sea of solar material that fills the solar system, and the Local Hot Bubble, a theorized area of hot interstellar material that surrounds our solar system.
“We show that the X-ray contribution from the solar wind charge exchange is about forty percent in the galactic plane, and even less elsewhere,” said Massimiliano Galeazzi, an astrophysicist at the University of Miami and an author on the study. “So the rest of the X-rays must come from the Local Hot Bubble, proving that it exists.”
However, DXL also measured some high-energy X-rays that couldn’t possibly come from the solar wind or the Local Hot Bubble.
“At higher energies, these sources contribute less than a quarter of the X-ray emission,” said Youaraj Uprety, lead author on the study and an astrophysicist at University of Miami at the time the research was conducted. “So there’s an unknown source of X-rays in this energy range.”
In the decades since we first discovered the X-ray emission that permeates space, three main theories have been bandied about to explain its origins. First, and quickly ruled out, was the idea that these X-rays are a kind of background noise, coming from the distant reaches of the universe. Our galaxy has lots of neutral gas that would absorb X-rays coming from distant sources – meaning that these X-rays must originate somewhere near our solar system.
So what could produce this kind of X-ray so close to our solar system? Scientists theorized that there was a huge bubble of hot ionized gas enveloping our solar system, with electrons energetic enough that they could release X-rays like this. They called this structure the Local Hot Bubble.

which keeps increasing the amount of cosmic rays in the form of x-rays reaching our Solar System and Earth.
You have not provided a source which says that.
Since then the amount of cosmic rays being sent our way by this mysterious source keeps increasing.

Anyway, just to add, according to NASA one of the fires in California was started by a camp fire.

Butte County's deadly Camp Fire was named after Camp Creek Road, the location where the fire started.

You are confused.
X-rays are not the same thing as cosmic rays. X-rays are electromagnetic radiation which travels at the speed of light. Cosmic rays are high energy particles which do not. Cosmic rays are affected by magnetic fields (if the particles are charge) and electromagnetic radiation is not.
But what makes you think the source of the high energy cosmic rays is the same as the source of the x-rays?

They need to enlist Native Americans to do preventative controlled burns, like they used to for thousands of years, before we wiped them out.
But instead we'll just blame it on "Climate Change" (all of our fellow citizens for living in modernity), and throw conniption fits and bark at the moon.

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...

California Forest Fires, are They Caused by Climate Change
Giant sequoias are the largesttrees on Earth. They can grow for more than 3,000 years. But without fire, they cannot reproduce.

Where Are Cosmic Rays in the Energy Spectrum?
Where do cosmic rays rays fall in the electromagnetic spectrum amidst the x-rays and microwaves?
Some people use "cosmic rays" to include high energy photons (light), and they basically mean x-rays and gamma-rays (light that is high enough energy that you measure individual photons, rather than taking pictures the way you do with visible, ultraviolet, microwave, etc.). I usually think of cosmic rays (which is my field of astrophysics) as only being the particles (pieces of atoms) which are moving at near the speed of light.
If you were to plot "cosmic rays" on an electromagnetic spectrum, it would basically encompass x-rays and everything higher in energy (higher in frequency or shorter in wavelength). I personally would leave it out, since I don't think it's a correct usage of "cosmic rays" (but I don't make the rules).

Quora? Ok, sure.
As i wrote in another thread.

Cosmic rays, though, usually mean high-energy particles with mass traveling through space. So, that definition excludes X-rays and gamma rays. Cosmic rays are mostly high-energy protons (90%) and alpha particles (9%), but include other high-energy particles, such as electrons and heavier atomic nuclei.
The 2008 discovery? No. Not X-rays. Those cosmic rays were detected by a balloon. There's a reason they use rockets and satellites to detect x-rays you know. Getting out of the atmosphere is a big plus.
The energy we are receiving from this mysterious source are high energetic x-rays.
