New Svalgaard paper – reconstructing the heliospheric magnetic field since 1835 – with insight into the peer review process

Leif Svalgaard writes in comments: We plan to submit tomorrow to JGR the following… http://www.leif.org/research/IDV09.pdf (preprint) …showing the run of the heliospheric magnetic field since 1835 [not a typo]. I plan to discuss the whole peer-review process here on WUWT, complete with nasty comments by the reviewers and our responses. This will be an illustration…

Aerosols and “cloud lifetime effect” cited as “enormous uncertainty” in global radiation balance

From a Press Release from the Max Planck Institute for Meteorology Do dust particles curb climate change? A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus…

NSIDC still pushing ice free Arctic summers

NSIDC seems to be saying: It’s slightly less worse than we thought. For another view, see Dr. Tony Berry’s sea ice analysis on WUWT yesterday. From a University of Colorado Press Release Arctic sea ice recovers slightly in 2009, remains on downward trend, says U. of Colorado report IMAGE: This graphics show multi-year Arctic sea…
