Top Astrophysicist Warns of Cosmic Rays Climate Impact

Written by Pierre Gosselin

Danish Professor Henrik Svensmark is a leading physicist of cosmic radiation.

At the end of last year, he made a presentation at the 12th International Climate Conference in Munich, where he demonstrated that the climate is indeed modulated in large part by cloud cover, which in turn is modulated by solar activity in combination with cosmic rays.

His theory is that cosmic rays, which are extremely fast-flying particles – which originate from dying supernovae – travel through the cosmos, strike the Earth’s atmosphere and have a major impact on cloud cover and thus climate on the Earth’s surface.

This, Svensmark says, has been confirmed in numerous laboratory experiments.

In his presentation, the renowned Danish scientist showed how solar activity modulates the cosmic rays striking the atmosphere, and thus the climate-impacting cloud cover.

Dr. Svensmark shows that there are powerful correlations worldwide between solar activity and climatic cycles, and so the sun is clearly playing a role in combination with the cosmic cloud-seeding rays. Hundreds of studies confirm this.

Observations and proxy data show that “when you have high cosmic rays, you have a cold climate” because of greater cloud cover.

According to Svensmark, the net effect of clouds is to cool the Earth by up to 30 W/m2.

Clouds are extremely important for the Earth’s energy budget. The net effect is about 20 to 30 watts per square meter.”

That figure is great in terms of impact on climate change, and it is grossly neglected by CO2-fixated climate scientists.

His research shows there is a clear link between low cloud cover formation and galactic cosmic rays:

Sun modulates the cosmic ray intensity hitting the Earth’s atmosphere

In his presentation (see video) he explains the mechanism of how the cosmic rays seed low-level clouds, which act to cool the climate.

In periods of intense solar activity, the sun’s magnetic field engulfs and shields the Earth’s atmosphere from the cloud-seeding cosmic rays, thus less low-level clouds are formed and the Earth warms.

Vice versa, i.e. during periods of low solar activity, the sun’s magnetic field is weaker, and so more cosmic rays are able to penetrate into the atmosphere and seed clouds. The resulting clouds act to cool the planet.

Confirmed by experiments

Svensmark’s experiments confirm that solar cycles impact energy changes in the oceans by an order of 1.5 W/m2 over an 11-year cycle and that his findings are consistent with climate changes over the Holocene and even geological times going back more than 100 million years.

Over geological history, especially when the Earth traveled through one of the spiral arms of the Milky Way, cosmic rays striking the atmosphere were very intense and thus led to extremely cold conditions known as the Snowball Earth episodes.

Other scientists insist the episodes were caused by intense volcanic eruptions.

Significant solar changes in Earth’s energy budget

Dr. Svensmark summarizes the solar activity/cosmic ray climate modulation system with the following chart:

In the end, changes in solar activity lead to significant changes in the earth’s energy budget, and thus climate change, Svensmark believes. This explains why the Earth has seen “coolings and warmings of around 2°C repeatedly over the past 10,000 years.”

He concludes:

The Sun became unusually active during the 20th Century and as a result part of the ‘global warming’ observed.”

    Yes. This was put forward in some detail in the UK Channel 4 documentary “The Great Global Warming Swindle”. The producers got taken to court for misrepresenting the science of global warming. NOT A JOKE !. The documentary ought to be shown to students as an alternative to the mainstream mantra. In my days at school, I was told that the main purpose of education was to teach us to think for ourselves (in the face of propaganda). These days, pupils are told what to believe. I’m almost glad I won’t be here long enough to see the total enslavement of our citizens.

    I Think climate change is real and as a normal people we should start taking appropriate measures now.

    Hi PSI Readers,

    “At the end of last year, he [Professor Henrik Svensmark] made a presentation at the 12th International Climate Conference in Munich, where he demonstrated that the climate is indeed modulated in large part by cloud cover”

    It seems I have been the only one pushing this ‘fact’. So, Pierre, thank you for brings this to our attention. But since this old idea Sutcliffe (Weather & Climate, 1966) has become a new idea, I consider we need to first explore what this ‘new’ old idea does to a ‘new’ understanding of the earth’s Weather & Climate systems without attaching some ‘possibly’ unnecessary perturbation upon the natural cloud system. More people beside the Professor and me, need to become involved in ‘creating’ this new understanding.

    Have a good day, Jerry

    Michael Mizkolsky wrote a paper on Cloud effects 2004.
    It is also fairly obvious that as climate warms there is more water in the atmosphere, at higher levels cooling generates more clouds, and precipitation. This has already happened with increased intensity in many rain events. These natural cycles combine with other interactions making climate theory much more chaotic and unpredictable than climate models. Multiple variables in solar activity are also adding to the chaos. ACO2 will likely be found to have a tiny contribution and human security and development will pay a very high price for this hubris.

      Hi Peter,

      Tried to Google Michael Mizkolsky several different ways without success. Do you have any information how I can find what he wrote?

      I question why you begin with the assumption that ‘climate’ is warming. I read that it is generally accepted that thick glaciers covered large portions of northern Europe, Asia, and North America and that the last of these glaciers melted only about 10,000 years ago. Now that I can accept as being climate warming. Or is this the result of continental drift?

      We have El Nino-La Nina event with some frequency Is the reason modelers cannot figure out these obvious ‘global’ events that they are using wrong ideas?

      Try to imagine what we happen if the modelers assumed the earth stood still. Until I read about the centrifugal effect, I have to assume they are considering that the earth doesn’t rotate. Until I read about diurnal temperature oscillations, I have to assume many are considering that the earth doesn’t rotate. Until I read about the diffusion of water molecules in the atmosphere have to assume many are not considering that the molecules of the atmosphere do move. I

      It is amazing what one cannot explain if one does not observe all that can be observed.

        Hi Jerry’
        El Nino-La Nina are easy to explain. The inertia of water and the spinning of the aEarth cause the equatorial currents to transfer warm water west. In the Atlantic this current is deflected north by Brazil causing the Gulf Stream. In the pacific the warm water runs into a bowl formed by the islands that causes the warm water to build up in a pool. Eventually this pool of warm water becomes hotter than the current moving the water to the pool. This causes the current to sink under the pool and push the warm water east on either side of the current.

          Hi Herb,

          A problem with your explanation is it does not address how, or why, there is this less than periodic oscillation of the El Nino–La Nina events separated by periods of what we observe (and consider) to be a ‘normal’ (common) circulation and temperature state of the atmospheric and oceanic systems.

    Cosmic rays also alter the decay rate of fissionable elements, fueling the variable volcanic furnace under our feet, effecting the release of the Sulfur molecules that are the cloud seeds that Svensmark mentions. He’s only half right.

    Here’s what I wrote about cosmic rays in December 2016 in the final paragraph in my third paper “Comprehensive Refutation of the Radiative Forcing Greenhouse Hypothesis” …

    “It may well be that magnetic fields from the planets (which we know reach to the Sun) affect the direction and perhaps intensity of cosmic rays which subsequently affect cloud formation on Earth. The temperature at the effective radiating altitude is determined after about 20% of the solar radiation has been reflected back to Space. That percentage would only have to vary between 19% and 21% for all climate change in the last 3,500 years to be explained. In all that time, annual mean global temperatures have varied by less than about 1%, so in fact the climate is quite stable and such variations do not impose serious life-threatening problems for mankind. Many more lives will be lost if the world continues to waste over a trillion US dollars a year on a problem that does not exist, rather than directing such funds to humanitarian aid.”
