Kort beskrivelse af Willie Soon:
Willie Soon is an astrophysicst and geoscientist at the Harvard-Smithsonian Center for Astrophysics of Harvard University and the Smithsonian Institution. Willie Soon is well-known in the American media for exposing the flaws and anti-science nature of the IPCC-initiated mockery of climate science in that only atmospheric CO2 will be able to drive past, present and future climate changes, including both global warming and global cooling. He was recently honored with the 2017 Frederick Seitz Memorial Award by Science and Environmental Policy Project.
Willie Soon er astrofysiker og geofysiker på The Harvard-Smithsonian Center for Astrophysics ved Harvard University og The Smithsonian Institution. Willie Soon er velkendt i amerikanske medier for at påpege den anti-videnskabelige natur af Det internationale Klimapanels (IPCCs), bl.a. hånlig adfærd over klimaforskning ved kun at anerkende, at ikke andet end atmosfærisk CO2 vil være i stand til at styre fortidens, nutidens og fremtidens klimaforandringer. Willie Soon har i 2017 modtaget The Frederick Memorial Award.
Abstract to Willie Soon’s talk on Monday 19th February, at 15:00 in the Geological and Geophysical Societies of Denmark:
Climate, Sun, Planets, Hurricanes
At times, our Sun appeared to have been transiting through a stable period, perhaps giving Earth the necessary stability for life to develop. However, intrinsic variations in solar activity and properties of the Sun-Earth’s orbits have caused very large and significant climatic upheavals and oscillations between ice ages and warm, humid periods on Earth which may in turn be speculated to be both necessary and sufficient for life to evolve in its full complexity and robust resiliency.
We will discuss the empirical evidence for both long and short solar activity variations ranging from interannual to bi-millennial timescales. We will approach this question not only based on direct observation of the Sun but also from both the observational study (and constraints) of solar-analog stars and the available solar activity proxies from Earth’s paleo-archives. We will interpret the empirical evidence with helps from both solar dynamo theory as well as Sun-planets orbital interaction framework. An emphasis will be placed on a new methodology for time series analysis using the cross-wavelet transform that is valid for N > 2 records. We will also feature in this talk how even an empirical understanding can lead to useful scientific predictions on certain key climate dynamics variables like the Equator-to-Pole temperature gradients rooted in the predictable seasonal insolation gradients.
