Real Climate’s Misinformation

From Climate Science — Roger Pielke Sr. @ 7:00 am

Real Climate posted a weblog on June 21 2009 titled “A warning from Copenhagen”.  They report on a Synthesis Report of the Copenhagen Congress which was handed over to the Danish Prime Minister Rasmussen in Brussels the previous week.

Real Climate writes

“So what does it say? Our regular readers will hardly be surprised by the key findings from physical climate science, most of which we have already discussed here. Some aspects of climate change are progressing faster than was expected a few years ago – such as rising sea levels, the increase of heat stored in the ocean and the shrinking Arctic sea ice. “The updated estimates of the future global mean sea level rise are about double the IPCC projections from 2007″, says the new report. And it points out that any warming caused will be virtually irreversible for at least a thousand years – because of the long residence time of CO2 in the atmosphere.”

First, what is “physical climate science”? How is this different from “climate science”. In the past, this terminology has been used when authors ignore the biological components of the climate system.

More importantly, however, the author of the weblog makes the  statement that the following climate metrics “are progressing faster than was expected a few years ago” ; Read the rest of this entry »

McIntyre on USHCN2’s “warmer” trend treatment of Orland

Orland CA and the New Adjustments

by Steve McIntyre on June 29th, 2009

In my last post, I observed that NOAA’s Talking Points applied their new “adjustments” to supposedly prove that NOAA’s negligent administration of the USHCN network did not “matter”.

In order to illustrate the effect of the new methods in this post, I’ll compare the new adjustments (post-TOBS) to the old adjustments (post-TOBS) on a “good” station – Orland CA, a prototype “good” station, discussed at the outset of surfacestations.org, discussed at WUWT here and CA here in early 2007.

The station history for Orland (at CDIAC) says that it has been in its present location for (at least) most of the 20th century and has had minimal changes during that time, other than perhaps time-of-observation (TOBS). The TOBS adjustment is carried forward into USHCN-v2. As I understand it, NOAA’s New Adjustment Method replaces station-history based adjustments for instrumentation changes and station location (the latter formerly done in FILNET).

As a benchmark, here is the difference between FILNET (adjusted) and TOBS for Orland in the “old” USHCN. Adjustments in the 20th century are negligible – in keeping with station history information that indicates no changes in location. Read the rest of this entry »

Tropical Tropospheric Amplification – an invitation to review this new paper

The Amplification Invitation

A while ago I started studying the question of the amplification of the tropical tropospheric temperature with respect to the surface. After months of research bore fruit, I started writing a paper. My intention was to have it published in a peer-reviewed journal. I finished the writing about a week ago.

During that time, I also wrote and published The Temperature Hypothesis here on WUWT. This got me to thinking about science, and about how we establish scientific facts. In climate science, the peer review process is badly broken. Among other problems, it is often an “old boy” system where very poor work is waved through. In common with other sciences, turnaround of ideas in journals takes weeks. Under pressure to publish, journals often do only the most cursory examination of the papers.

Upon reflection, I have decided to try a different way to examine the truth content of my paper. This is to invite all of the authors whose work I discuss, and other interested scientists of all stripes, to comment on the paper and on whether they can find any flaws in it. To facilitate the process I have provided all of the code and data that I used to do the analysis.

To make this process work will require cooperation. First, I ask for science and science only. No discussions of motives. No ad homs. No generalizations to larger spheres. No asides. No disrespect, we can be gentlemen and gentlewomen. No comments on politics, CO2, or AGW, no snowball earth. This thread has one purpose only, to establish whether my ideas stand: to either attack and destroy the ideas I put forth in the paper below, or to provide evidence and data to support the ideas I put forth below.
