Tom Harris is executive director of the Ottawa, Canada-based International Climate Science Coalition. Tim Ball is an environmental consultant and former climatology professor at the University of Winnipeg in Manitoba: The best answer to most of the claims by climate activists and their political allies is simply: so what? "Climate change is real," they say. So what? Gravity and sunrise are also real. That doesn't mean we cause them or we would be better off without them.

Judith Curry, Pope Francis: From the Vatican - World leaders meeting at the Vatican for a conference on climate change have issued a final statement, declaring that “human-induced climate change is a scientific reality” and “its decisive mitigation is a moral and religious imperative for humanity.” The statement says that humans have the technological and financial means, and the know-how, to combat human-induced climate change, while at the same time eliminating global poverty. Judith Curry - The debate on climate change has centered on the science and economic cost/benefit analyses – both of which are dominated by deep uncertainties. The moral dimensions of the climate change problem have received short shrift.
James Lovelock: So should we be trying to save the world? “Don’t try and save the world, its pure hubris. We might be able to save Dorset. I think it’s easier to save Dorset than the planet. “There’s one thing to keep in mind here. We don’t need to save the planet, it’s looked after itself for four billion years. It’s always been habitable and things have lived on it, so why worry.” At the end of the day, “It pays to be cheerful,” he says.
Uli Weber, Geophysiker: www.kaltesonne.de - Das Problem: Der natürliche Kohlenstoffdioxid-Kreislauf (Abbildung 1) auf unserem Planeten Erde steht in Verdacht, durch den industriellen CO2-Eintrag des Menschen aus den Fugen zu geraten und eine globale Klimakatastrophe zu verursachen. Aber ist dieser natürliche CO2-Kreislauf überhaupt voll verstanden und richtig in die Computermodelle zur Vorhersage des zukünftigen Klimas eingegangen?
