Uli Weber, Geophysiker und Publizist: Jede wissenschaftliche Theorie und jedes wissenschaftliche Theorem kann durch einen einzigen schlüssigen Gegenbeweis widerlegt werden. Und jetzt stellen Sie sich einmal vor, sie hätten einen ganz eklatanten Widerspruch in einer wichtigen physikalischen Berechnung entdeckt, der die Welt, so wie sie uns erklärt wird, nachhaltig verändern würde – oder besser ausgedrückt, Sie glauben entdeckt zu haben, dass es gar nicht notwendig wäre, unsere Welt durch eine Dekarbonisierung bis zum Jahre 2100 vor einer menschengemachten Klimakatastrophe zu retten.
Bryan Leyland, power systems design, mechanical engineer: We constantly hear that our present way of life is unsustainable because the world is running out of fossil fuels and other vital resources. People in developed countries are healthier and live longer than in the past. Abundant energy, engineering, technology and modern medicine have driven this transformation. We have progressed from eking out a living from subsistence agriculture to having plenty of time for recreation and relaxation and living better than a king 300 years ago. Nevertheless, billions of people are still living in poverty, and they and we need good governance and economic growth from using the best available technology to ensure that goods are supplied at the lowest cost and that energy is used efficiently and wisely.
Paul Driessen is senior policy analyst for the Committee For A Constructive Tomorrow (www.CFACT.org) and author of Eco-Imperialism: Green power - Black death. Worry less about manmade climate cataclysms – and more about cataclysms caused by policies promoted in the name of controlling Earth’s climate. Don’t force-feed us with today’s substandard, subsidized, pseudo-sustainable, pseudo-renewable energy systems. When better, more efficient, more practical energy technologies are developed, they will replace fossil fuels. Until then, we would be crazy to go down the primrose path to renewable energy utopia.
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.
