• Mike Hulme: The Science and Politics of Climate Change - WSJ.com: "These instinctive reactions fail to place the various aspects of our knowledge about climate change—scientific insights, political values, cultural moods, personal beliefs—in right relationship with each other. Too often, when we think we are arguing over scientific evidence for climate change, we are in fact disagreeing about our different political preferences, ethical principles and value systems."
• Quinta do Sargaçal – Literatura céptica: "Um anónimo inteligente deixou num comentário do Ambio uma lista de 450 artigos sujeitos a arbitragem científica supostamente escritos pelos cépticos climáticos. É um número impressionante e o Miguel B. Araújo achou curioso — porque suponho eu —, tanto quanto se sabe, artigos sujeitos a arbitragem científica a negar o aquecimento global são muito poucos."

• Copenhagen: The era of climate stability is coming to an end | Environment | The Guardian: "For about 10,000 years, our climate on Earth has been stable. Remarkably stable, in fact. Since the end of the last ice age, we humans have spent 400 generations taking advantage of this stability to build our civilisation. We have had warm periods and little ice ages; but the changes have been small. We have always known pretty much when it will rain, what the temperature will be each summer and winter, and how high the rivers will flow. This benign climate is arguably the main reason why our species has been able to progress. Why, within 400 generations, we have gone from the scattered tribes of spear-carriers and fire-raisers who emerged from their caves at the end of the ice age to become the first farmers, metallurgists, urbanists, industrialists and now the seven billion inhabitants of a digitised, globalised world."
