Do You Think This Cloud Experiment is Important?

The aim of CLOUD is to understand whether or not cosmic rays can affect clouds and climate, by studying the microphysical interactions of cosmic rays with aerosols, cloud droplets and ice particles.” This is one of the possible mechanisms for solar-climate variability since the solar wind – the stream of charged particles ejected from the sun – varies over time and affects the intensity of the cosmic rays that reach the Earth.See: On Cloud Nine

I have always refrained from speaking on the climate change topic mostly because I really did not know enough. I was uncertain as to whether we really had all the facts about what was taking place. This in no way was to limit the perspective on how we can make our world a better place, or create a better environ.

I just wanted these facts included in the assessment in terms of what scientists are actually doing now.  This then opens the mind up to whether the process here is valid one to take into consideration along with how we view climate change.

Historically the validation of the process, it is necessary to converge on some notation about it’s beginnings to know that it can evolve to what it is today. This is a necessary part of moving forward in experimental validation processes toward foundational thinking and our actions in the future. Our Actions now.

CLOUD – Cosmics Leaving OUtdoor Droplets

CLOUD is an experiment that uses a cloud chamber to study the possible link between galactic cosmic rays and cloud formation. Based at the Proton Synchrotron at CERN, this is the first time a high-energy physics accelerator has been used to study atmospheric and climate science; the results could greatly modify our understanding of clouds and climate.
Cosmic rays are charged particles that bombard the Earth’s atmosphere from outer space. Studies suggest they may have an influence on the amount of cloud cover through the formation of new aerosols (tiny particles suspended in the air that seed cloud droplets). This is supported by satellite measurements, which show a possible correlation between cosmic-ray intensity and the amount of low cloud cover. Clouds exert a strong influence on the Earth’s energy balance; changes of only a few per cent have an important effect on the climate. Understanding the underlying microphysics in controlled laboratory conditions is a key to unravelling the connection between cosmic rays and clouds.

The CLOUD experiment involves an interdisciplinary team of scientists from 18 institutes in 9 countries, comprised of atmospheric physicists, solar physicists, and cosmic-ray and particle physicists. The PS provides an artificial source of ‘cosmic rays’ that simulates natural conditions as closely as possible. A beam of particles is sent into a reaction chamber and its effects on aerosol production are recorded and analysed.

The initial stage of the experiment uses a prototype detector, but the full CLOUD experiment will include an advanced cloud chamber and a reactor chamber, equipped with a wide range of external instrumentation to monitor and analyse their contents. The temperature and pressure conditions anywhere in the atmosphere can be re-created within the chambers, and all experimental conditions can be controlled and measured, including the ‘cosmic ray’ intensity and the contents of the chambers.See:CLOUD–Cosmics Leaving OUtdoor Droplets

Again I am remaining open to all points of view that are scientifically based and point toward a better understanding of our relationship with the effects of what we are doing to our planet.
