A new study published in the peer-reviewed journal Space Weather reports the discovery of radiation "clouds" at aviation altitudes. When airplanes fly through these clouds, dose rates of cosmic radiation normally absorbed by air travelers can double or more.

The global climate anomaly
1940–1942
...
The cold European winters during the Second World War (1941/42 was the third in a row) are famous. They even affected the course of the war (Lejenäs 1989). However, it is less well-known that at the same time climate was also anomalous in other regions of the world. Temperatures were exceptionally high in Alaska, and a prolonged El Niño was reported. Moreover, scientists noted unusually high values of total ozone over several European sites. The cold winters in Russia were merely a facet of a global climate anomaly encompassing the troposphere and stratosphere, a fact that was not realised until recently (Brönnimann et al. 2004a, Labitzke and van Loon 1999).

The measurements from 2013 to 2016 do not cover a period of time to quantify galactic cosmic rays' dependence on solar cycle variation and their effect on aviation radiation.

The article makes no connection to climate whatsoever. That is purely your imagination.
OK, here is the plan... the magnetic field is changing due to mans use of electricity (electrical production and the transport of electricity worldwide is disrupting the natural magnetic field of the earth!).... Now, we can get a coalition of scientists to hit the government up for millions for research (I get 5%) and have Al Gore make another movie (with me not Hansen) and if we preach this well enough we can make a crap-ton of money just on the books alone....
Now, if it goes really well after that, we can then press for "electron credits" and "electron Cap & Trade" scams.
Then an international court to "punish" those who do not comply with paying us to prevent this disaster and doing what we tell them in the name of the environment. I hereby repeat my claim this scam ... err, I mean scientific discovery and disclosure of the greatest threat to mankind ever, publicly and originally on the internet on 1/11/2009 and we will call this the "Infolurker Effect" going forward!
We will make a mint by taxing every kilowatt of electricity produced in the WORLD! This is almost as good as the Co2 scam and nobody has claimed it yet so I am..
Not this discussion again...we already spent pages going through this in another thread while you were trying to figure out how to read a simple graph.

Are you Phage now claiming that an increase in cosmic radiation reaching Earth would not affect Earth's atmosphere and it's climate? Because that is "your imagination" if that's what you are implying.

We also discussed that you couldn't even prove what effect an increase in cosmic rays would have on the climate, such as whether it would result in a temperature increase, or a temperature decrease, or no significant effect.
Declining solar activity linked to recent warming
The Sun may have caused as much warming as carbon dioxide over three years.
Quirin Schiermeier
An analysis of satellite data challenges the intuitive idea that decreasing solar activity cools Earth, and vice versa. In fact, solar forcing of Earth's surface climate seems to work the opposite way around — at least during the current Sun cycle.
Joanna Haigh, an atmospheric physicist at Imperial College London, and her colleagues analysed daily measurements of the spectral composition of sunlight made between 2004 and 2007 by NASA's Solar Radiation and Climate Experiment (SORCE) satellite. They found that the amount of visible light reaching Earth increased as the Sun's activity declined — warming the Earth's surface. Their unexpected findings are published today in Nature1.
The study period covers the declining phase of the current solar cycle. Solar activity, which in the current cycle peaked around 2001, reached a pronounced minimum in late 2009 during which no sunspots were observed for an unusually long period.
Sunspots, dark areas of reduced surface temperature on the Sun caused by intense magnetic activity, are the best-known visible manifestation of the 11-year solar cycle. They have been regularly observed and recorded since the dawn of modern astronomy in the seventeenth century. But measurements of the wavelengths of solar radiation have until now been scant.
Radiation leak
Haigh's team compared SORCE's solar spectrum data with wavelengths predicted by a standard empirical model based mainly on sunspot numbers and area, and noticed unexpected differences. The amount of ultraviolet radiation in the spectrum was four to six times smaller than that predicted by the empirical model, but an increase in radiation in the visible wavelength, which warms the Earth's surface, compensated for the decrease.
Contrary to expectations, the net amount of solar energy reaching Earth's troposphere — the lowest part of the atmosphere — seems to have been larger in 2007 than in 2004, despite the decline in solar activity over that period.
The spectral changes seem to have altered the distribution of ozone molecules above the troposphere. In a model simulation, ozone abundance declined below an altitude of 45 kilometres altitude in the period 2004–07, and increased further up in the atmosphere.
The modelled changes are consistent with space-based measurements of ozone during the same period.
"We're seeing — albeit limited to a very short period — a very interesting change in solar irradiation with remarkably similar changes in ozone," says Haigh. "It might be a coincidence, and it does require verification, but our findings could be too important to not publish them now."
Sun surprise
The full implications of the discovery are unclear. Haigh says that the current solar cycle could be different from previous cycles, for unknown reasons. But it is also possible that the effects of solar variability on atmospheric temperatures and ozone are substantially different from what has previously been assumed.

The chart you show seems to show solar activity related to the 11 year solar cycle (as are soft x-ray and radio emissions), the previous minimum being in 2009. It is quite normal for solar activity to increase after the solar minimum and to decrease after the maximum.
I even showed you that astrophysicists were pointing this out, and that the new instruments detecting this activity in our sun was actually showing an increase in activity the sun (visible light and soft x-rays) has been emitting in a time when the sun's other activity, such as sunspots has slowed to a crawl.

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.

Interesting article from Nature. But it does not say that TSI increased between 2004 and 2007, nor does the data. But what it does say is that the assumed (by some) link between solar activity and climate may be inverse rather than direct.

That is not what your source says. Really. It does not say that. If you look at the data (and the study) there was no increase in TSI over the period of the study. You seem to be confusing TSI with the radiation received at the top of the troposphere.
Except for the fact that during this cycle sunspots had slowed down and instead of the sun reducing the amount of energy it emitted soft x-ray emissions and visible light increased.
