(52 min)Video quotes:
) ”There is a problem that has always been with us: New ideas are rarely welcome in science when particularly some young person not known in the field proposes some radical new idea, it may experience great difficulty in getting it published.”
~ Eugene Parker, Professor Emeritus of Physics, Astronomy and Astrophysics at University of Chicago.
) ”When we published this in 1991” … “What we could see was that when the magnetic activity of the Sun was larger, then the temperature on the Earth was higher.”
~ Eigil Friis-Christiansen, Director DTU Space at Technical University of Denmark.
) ”We know now that the Sun’s magnetic field has increased, and we know the Sun is more more active, the activity has been increasing the last hundred years by a factor of two.”
~ Paal Brekke, Solar Physicist, former Deputy Project Scientist at the SOHO Satellite Project.
) ”Whereas most people would think that since there’s water in the atmosphere that naturally there’ll be clouds, but that is untrue. The only way that clouds can form in the atmosphere, in our atmosphere, under normal conditions is to condense onto an aerosol or existing particle in the air. Every cloud droplet that’s formed is formed on a particle initially in the air. All clouds are formed upon these aerosols.”
~ Richard Turco, Director of UCLA Institute of the Environment.
) ”The Solar System move in and out of the spiral arms, and the spiral arms are the regions where you have the new stars, and the new stars is
[sic] also, some of them, the heavy stars will live very shortly and explode in supernova. That means that you have more cosmic rays as you move in to the arm, spiral arms.”
~ Henrik Svensmark, Head of Center for Sun Climate Research, DTU Space at Technical University of Denmark.
) ”If we look at the Milky Way from the top what we’ll see are four spiral arms and that is because the Milky Way is a spiral-armed galaxy, so we have four spiral arms. We are located here on some small armlet. We’re rotating around the Sun once every year, but the whole Solar System rotates around the Milky Way once every about two hundred and fifty million years, that’s one galactic year. Which this means is that every a hundred and fifty million years, when we pass through a spiral arm of the galaxy it’s colder by something about five degrees or ten degrees, and when we are outside of the spiral arm it’s hot. Now we are on this small spiral arm so we are witnessing cold weather.”
~ Nir Shaviv, Astrophysicist at the Hebrew University of Jerusalem.
) ”When I looked at the data I realised that actually there were some oscillations in the general trend of temperature and that those oscillations fitted quite well with what we knew from Geology what kind of a climate was at that time. Working with the colleagues we did evaluation and statistical study of that and we saw that there was some kind of periodicity roughly over about one hundred and forty million years switching back and forth between hothouse and icehouse. I suspected that the reason for that periodicity was something to do with the sky but I was searching for it and couldn’t find anything.”
~ Jan Veizer, Professor Emeritus of Earth Sciences at the University of Ottawa.
