The Faith Component of Global Warming Predictions

By Dr Roy Spencer – Re-Blogged From http://www.drroyspencer.com

It’s been ten years since I addressed this issue in a specific blog post, so I thought it would be useful to revisit it. I mention it from time to time, but it is so important, it bears repeating and remembering.

Over and over again.

I continue to strive to simply these concepts, so here goes another try. What follows is as concise as I can make it.

  1. The temperature change in anything, including the climate system, is the result of an imbalance between the rates of energy gain and energy loss. This comes from the First Law of Thermodynamics. Basic stuff.
  2. Global warming is assumed to be due to the small (~1%) imbalance between absorbed sunlight and infrared energy lost to outer space averaged over the Earth caused by increasing atmospheric CO2 from fossil fuel burning.
  3. But we don’t know whether the climate system, without human influence, is in a natural state of energy balance anyway. We do not know the quantitative average amounts of absorbed sunlight and emitted infrared energy across the Earth, either observationally or from first physical principles, to the accuracy necessary to blame most recent warming on humans rather than nature. Current best estimates, based upon a variety of datasets, is around 239-240 Watts per sq. meter for these energy flows. But we really don’t know.

Professional Associations’ Position Statements

By Kip Hansen – Re-Blogged From WUWT

featured_imageThe internet information pipe is gushing out information faster than most people can handle.  It is increasingly difficult to sort and strain that information flow to find the bits that are important for one’s work.  One of my many filters is the continuing series of blog posts by Judith Curry, titled “Week in review – science edition”, in which Dr. Curry lists science articles, studies, blog posts and the like that “caught her eye” in the preceding week(s).  She not only lists pieces that have added to our knowledge base and represent “a lot of progress in climate science” but she includes interesting bits that relate often to the philosophy and practice of science in general.  Her suggestions lead to her readers pulling the threads and offering follow-up sources of ideas.  One of those follow-ups, offered to us by Climate Etc. reader “Faustino” led me to an article on Quillette.com (“a platform for free thought”) titled “Motivated Reasoning Is Disfiguring Social Science” written by Chris Ferguson.

Getting the Public’s Attention on Global Warming

By Dr. Tim Ball -Re-Blogged From http://www.WattsUpWithThat.com

It is 28 years since Channel 4 in the UK produced The Greenhouse Conspiracy. It covered almost all the skeptical critiques. They are still valid, but now they are time -tested. Sadly, even today most people would not understand what was said in the movie and how it disproves the claim of anthropogenic global warming (AGW). Encouragingly, there are some signs that the continued efforts of the global warming skeptics are influencing public opinion, but overall little has changed. The public is in a holding pattern, knowing something is wrong but not reaching a final understanding for several reasons including that:
