Stephan Savarese, research engineer. President of Sauvons le Climat, Saving Our Planet: https://savingourplanet.net: Whatever the reasons for climate change, it's here and it's big. I name it Climate Transition because Climate Change has become a political issue. Showing pictures of isolated cold episodes in narrow regions of the world is picturesque, but cannot change the accurate, revised, precise statistics, which show that global warming has accelerated (at least) fourfold within the past fifty years, at a rate surprisingly fast and chaotic. As a consequence, ocean level rise, which had stabilized over the past five millennia at 1 mm/year, is on the verge of crossing the 5 mm/year mark, due to accelerated sea water thermal expansion, plus continental glacier melting.

Jean-Luc Salanave, Le développementfulgurantdes énergies solaire, photovoltaïque etéolienne,en ce débutde XXIe siècle, nous faitaussi expérimenter leurs inconvénients.La technologie en solutionnera bon nombre,mais intermittence etencombrementdemeurerontdes défauts majeurs de ces deux sources d’énergie tantqu’il y aura des absences de soleil ou de vent,etque 10 milliards de terriens auront besoin de surfaces habitables,cultivables etde forêts. Conclusion Pour satisfaire ses besoins énergétiques,l’homme ne disposera de rien d’autre que des trois seules forces fondamentales que la nature metà sa disposition :la force électromagnétique (énergies chimiques,combustibles fossiles,biomasse,photovoltaïque,…),la gravitation (énergies hydraulique,éolienne,inertielle,potentielle …) et les forces nucléaires (radioactivité,fission,fusion).

Ed Berry, Physicist and Patric Moore, Environmentalist: They both consider that CO2 from human emissions is not causing serious man-made global warming, serious other climate change effects, nor serious rise in ocean levels. In this discussion, they debate which view, logic, reasons are correct for the conclusion that they share about CO2 from human emissions.

Barry Brook, Faculty of Science, Engineering & Technology, U. of Tasmania, Australia & Staffan Qvist, Dept. of Physics and Astrophysics, Uppsala University, Sweden: This documents the excellent French and Swedish nuclear power plant construction programs in the 1960s to 1990s. It then extrapolates to a prediction that the whole world could be on 100 % nuclear power within 25 - 34 years. This must assume that the rest of the world has similar government support and cooperation, similar stable, honest leadership, sound economies, industrial capabilities, education systems, etc. and that the construction companies and nuclear fuel demands for France and Sweden can be quickly increased to those of the whole world. It assumes that the world will use the same nuclear technology as the Swedish and French programs of the 1970s to 90s. In reality, it may take several hundred years to replace 50% of fossil fuels with advanced nuclear technologies that still need development and testing.
