IPCC SPM – So What’s new?

February 2nd, 2007 · 4 Comments

Much of the information that is in the IPCC Summary for Policymakers is not news to those of us who are in the atmospheric science community and follow the literature. Even though we try, things do tend to slip through the cracks, and it takes someone (or 2500+ people, to be precise) to distill the [...]

Quantifying Climate Change

January 26th, 2007 · 4 Comments

I was going to post about some recent cavity ring-down experiments, but unfortunately for CRD-enthusiasts (any maybe fortunately for everyone else), an article appearing earlier this month in GRL on quantifiably defining climate change as a single index and using this lone index to explore climate change through the end of this century caught my [...]

Convectively-detrained cloud ice and enhanced WV feedback

October 24th, 2006 · 1 Comment

An interesting new article came out this week in GRL on clouds and water vapor feedback entitled Does convectively-detrained cloud ice enhance water vapor feedback?, by V. John and B. Soden at the University of Miami. Well, to cut to the chase, the answer is NO, according to this article. John and Soden show that [...]

Cubic Ice and Persistent Ice Supersaturation

September 25th, 2006 · 4 Comments

A couple of weeks ago, a new GRL paper on cubic ice came out entitled “Measurements of the vapor pressure of cubic ice and their implications for atmospheric ice clouds” (Shilling et al.). The paper’s authors includes several people associated with our department here at CU including Maggie Tolbert, Brian Toon, and Eric Jensen. In [...]

Still a thorn in our side / Positive cloud feedback?

July 17th, 2006 · 8 Comments

Cloud feedback still largest source of uncertainty in GCM’s What did they say? Clouds a positive feedback? Last week, a new article by Brian Soden of the University of Miami and Isaac Held of GFDL entitled “An Assessment of Climate Feedbacks in Couopled Ocean-Atmosphere Models” was published in the Journal of Climate. Among their findings [...]
