negative feedback, definition of

Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5730 years. Carbon is one of the few elements known since antiquity. The name "carbon" comes from Latin language carbo, coal.

• Demystifying feedback.
  Guest post by Nick Stokes, People outside climate science seem drawn to feedback analogies for climate behaviour. Climate scientists sometimes make use of them too, although they are not part of GCMs. But it gets tangled. In fact, all that the feedback...
• Another negative climate feedback: more CO2 = more plants = more aerosols = cooling
  Recall a couple of days ago that I posted on the aerosols released by trees: Those dirty trees: why hasn’t the EPA called for trees to be regulated? Now, from the International Institute for Applied Systems Analysis  comes a cause-effect … Continue...

  Oh dear, now we have three peer reviewed papers (Lindzen and Choi, Spencer and Braswell, and now Richard P. Allan) based on observations that show a net negative feedback for clouds, and a strong one at that. What will Trenberth … Continue reading...
