Para continuar a ler em Science stunner: “Clouds Appear to Be Big, Bad Player in Global Warming” — an amplifying feedback (sorry Lindzen and fellow deniers) « Climate Progress: - O início do artigo:
"The best evidence is that the climate is now being driven by amplifying feedbacks (see Study: Water-vapor feedback is “strong and positive,” so we face “warming of several degrees Celsius”), most notably:
- The defrosting of the permafrost
- The drying of the Northern peatlands (bogs, moors, and mires).
- The destruction of the tropical wetlands
- Decelerating growth in tropical forest trees — thanks to accelerating carbon dioxide
- Wildfires and Climate-Driven forest destruction by pests
- The desertification-global warming feedback
- The saturation of the ocean carbon sink
In spite of all evidence to the contrary, the deniers/delayers/inactivists, led by MIT’s Richard Lindzen, have argued that negative feedbacks dominate the climate system. In particular, they have asserted that clouds are a negative feedback. A major new study in Science from “Observational and Model Evidence for Positive Low-Level Cloud Feedback” (subs. req’d) is thus a potentially huge — and worrisome — piece of research."
