From the British Antarctic Survey , at least they didn’t pull a Steig and try to claim the observed effect on the Peninsula affects the entire continent. The peninsula is essentially a different Koppen climate class than the main continent, and is at the whim of changes in ocean currents and the SAM, plus Sea…
International study: Where there’s smoke or smog, there’s climate change By Hannah Hickey In addition to causing smoggy skies and chronic coughs, soot – or black carbon – turns out to be the number two contributor to global warming. It’s second only to carbon dioxide, according to a four-year assessment by an international panel. The…
I wonder how long it will be before Al Gore tries to blame ball lightning on “dirty weather”? A neat video follows. From CSIRO: Goodness, gracious, great balls of lightning Sightings of balls of lightning have been made for centuries around the world – usually the size of a grapefruit and lasting up to twenty seconds…
Dr. Roger Pielke Sr. highlighted this major new paper in JGR yesterday, I consider it important as it relates to the works I’m doing on station siting. The key points of the paper are supportive of what I’ve been saying for years, and show a significant effect on temperature trends, just as we’ve noted in…
From the University of Arizona (h/t to WUWT reader Miguel Rakiewicz): A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales. Climate-prediction models show skills in forecasting climate trends…
My sincere thanks to everyone who has provided widespread review of our draft paper. There have been hundreds of suggestions and corrections submitted in comments and in email, and for that I am very grateful. That sort of input is exactly what we hoped for, and such input can only make the paper better, and…
Whoa, this is heavy. Ross McKitrick, who was a peer review referee for the BEST papers with the Journal of Geophysical Research got fed up with Muller’s media blitzing and tells his story: excerpts: In October 2011, despite the papers not being accepted, Richard Muller launched a major international publicity blitz announcing the results of…
From Dr. Roger Pielke Sr. comes word of an important new paper that shows how the air near the ground (boundary layer) is highly affected by sensitive nighttime dynamics, which show up in the Tmin of weather station data (GHCN stations in this case) but are not captured by climate models. The paper also showed…
A paper published Friday in the Journal of Geophysical Research (GRL) finds that a known and natural atmospheric oscillation, the Southern Annular Mode or SAM, is correlated with observed increases in cloud cover resulting in regional cooling of approximately -2.5C. See for example this comparison from the paper with MODIS satellite data: From UCAR: The…
From the University of California – Santa Barbara In what might be the first study to report continuous measurements of net CO2 exchange of urban vegetation and soils over a full year or more, scientists from UC Santa Barbara and the University of Minnesota conclude that not only is vegetation important in the uptake of…
