Climate Etc.’s greatest “hits” for 2010

by Judith Curry

Climate Etc.’s first post was on Sept 2, 2010.  Since then, there have been 82 posts and over 26,000 comments.  The WordPress stats counter provides all sorts of interesting information. Which posts do you think got the largest number of hits?

Sociology of scientists discussion thread

by Judith Curry

This thread is “linky not thinky” on my part.  Over the past week, there have been some very interesting posts in the blogosphere that can be loosely grouped under a topic of “sociology of scientists,” many of which are relevant to previous Climate Etc. threads.

Climate Feedbacks: Part I

by Judith Curry

Everybody talks about climate feedbacks, but what are they, really?  And where did the expression ΔTs = λRF actually come from?

Scenarios: 2010-2030: Part II

Part I introduced the challenges of climate prediction on decadal scales, specifically in the context of global climate model simulations. On the Part I thread, Paul_K writes:

Scenarios: 2010-2030. Part I

by Judith Curry

On the time scale of a few decades ahead, regional variations in weather patterns and climate will be strongly influenced by natural internal variability. The potential applications of high resolution decadal climate change predictions are described in this CLIVAR doc.  Based upon my own interaction with decision makers, I see a need on these time scales that is primarily associated with infrastructure decisions.  Sectors that seem particularly interested in predictions on this time timescale are city and regional planners, the military, and the financial sector.

Washington update: science integrity

by Judith Curry

Over the past week, there have been several notable events on the “Hill” of relevance to U.S. science policy, addressing issues of concern related to the integrity of science.  In a word, Bravo!

Radiative transfer discussion thread

The continuing large traffic on previous threads on the topic of radiative transfer (and increasingly on threads with unrelated topics) has demonstrated the need for a new thread.  Here are some posts to start the new discussion over here:

Understanding conservative religious resistance to climate science

This post is a Q&A with Dr. David Gushee, who is Distinguished Professor of Christian Ethics at Mercer University, his personal web site is here and Wikipedia bio is here.

Climate model verification and validation: Part II

I’m starting a new thread for this topic, since interest in the previous thread has re-generated owing to this AGU abstract by Steve Easterbrook, entitled Do Over or Make Do?  Climate Models as a Software Development Challenge.

Scientists in fiction

Judith Curry

I recently read Ian McEwan’s book Solar, which motivated me to ponder putting together a thread on scientists in fiction.   The classics in this genre, e.g. Frankenstein, Dr. Jekyll and Mr. Hyde, Dr. Strangelove, represent scientists as evil geniuses unrestrained by ethics.  Contemporary books in the genre provide more complex images of scientists.

AGU Fall Meeting: Part II

by Judith Curry

I’ve spent the last several days at the AGU meeting in San Francisco.  With 19,200 participants, there is an overwhelming amount things going on all that the same time.   Here are some highlights of the meeting (some of which I witnessed first hand, others are based on second hand reports).  And also some comments on some of the controversies that are being discussed in the blogosphere.

Michaels’ controversial testimony: Part III

by Judith Curry

Pat Michaels’ frequent collaborator, Chip Knappenberger, has written an extended post on MasterResource that is a follow up to Michaels’ testimony and Climate Etc. previous two threads.  Chip has given me permission to repost in entirety at Climate Etc., and Chip will be available for discussion.

Lies, damned lies, and science(?)

by Judith Curry

A fascinating article appeared in the November issue of the Atlantic, entitled “Lies, Damned Lies, and Medical Science.”  The article is an absolute must read, about the prevalance of (unconscious) bias in medical science.

CO2 no-feedback sensitivity: Part II

by Judith Curry

So how to define this problem to make sense?  Or can we?  To focus the discussion started on the previous thread, I am highlighting some of the defining or thought provoking statement from the the previous thread:

AGU Fall Meeting

by Judith Curry

The American Geophysical Union (AGU) is holding is annual Fall meeting this week (13-17 Dec) in San Francisco.  I’m posting on this to give the broader Climate Etc. a sense of the main professional society for climate scientists.

CO2 no-feedback sensitivity

by Judith Curry

The IPCC defines climate sensitivity as “a metric used to characterise the response of the global climate system to a given forcing. It is broadly defined as the equilibrium global mean surface temperature change following a doubling of atmospheric CO2concentration.”

Open thread: 12/08/10

Unusual for me to post an open thread mid week, but this has unexpectedly turned into a very busy week for me.  Responding to the follow up questions is turning into as much work as the original testimony (even with all that help from my friends :) )

Education versus indoctrination: Part III

Education versus indoctrination: Part II

by Judith Curry

The previous thread has gotten long, and has wandered off topic.  Lets focus the discussion on this thread on some of the interesting ideas that are being discussed on the previous thread, including the following:

Confidence in radiative transfer models

by Judith Curry

The calculation of atmospheric radiative fluxes is central to any argument related to the atmospheric greenhouse/Tyndall gas effect.  Atmospheric radiative transfer models rank among the most robust components of climate model, in terms of having a rigorous theoretical foundation and extensive experimental validation both in the laboratory and from field measurements.   However, I have not found much in the way of actually explaining how atmospheric radiative transfer models work and why we should have confidence in them (at the level of technical blogospheric discourse).  In this post, I lay out some of the topics that I think need to be addressed  in such an explanation regarding infrared radiative transfer.  Given my limited time this week, I mainly frame the problem here and provide some information to start a dialogue on this topic, I hope that other experts participating can fill in (and I will update the main post).
