Scientists claim: Greenhouse gases largely to blame for warming oceans

Another “the science is settled” moment. From the ABC: A new US-led study, featuring research by Tasmanian scientists, has concluded that warming ocean temperatures over the past 50 years are largely a man-made phenomenon. Researchers from America, India, Japan and Australia say the study is the most comprehensive look at how the oceans have warmed.…

Another paper shows that severe weather/extreme weather has no trend related to global warming

From Pierre Gosselin’s  Notrickszone http://notrickszone.com/2012/05/25/comprehensive-alps-study-clearly-refutes-humans-are-causing-more-weather-variability-and-extremes/ A new paper authored by Reinhard Böhm of the Austrian Central Administration For Meteorology (ZAMG) refutes the notion that anthropogenic warming is causing an increase of climate extremes and making weather more variable and extreme. Pressure – temperature – precipitation (Source ZAMG) The paper uses the monthly resolved data of the HISTALP data…

Natural Variability in the Widths of the Tropics

Guest Post by Willis Eschenbach In my previous post, “Does This Analysis Make My Tropics Look Big?“I discussed a paper called “Recent Northern Hemisphere tropical expansion primarily driven by black carbon and tropospheric ozone”, by Robert Allen et al, hereinafter A2012. They use several metrics to measure the width of the tropics—the location of the…

Does This Analysis Make My Tropics Look Big?

Guest Post by Willis Eschenbach There is a new paper in Nature magazine that claims that the tropics are expanding. This would be worrisome because it could push the dry zones further north and south, moving the Saharan aridity into Southern Europe. The paper is called “Recent Northern Hemisphere tropical expansion primarily driven by black…

Weather is climate, or loaded dice, or something

From the Potsdam Institute for Climate Impact Research (PIK)  more instituitional worrying turned press release leading up to the upcoming WMO report. I wonder where they get the increase in hurricane intensity from? Apparently they’ve never seen Dr. Ryan Maue’s ACE graph discussed recently in the GRL journal:  “Historical global tropical cyclone inactivity (Editor’s Highlight):…

Nature endorses open source software in journal submissions

Ron Dean writes in Tips and Notes: Interesting article about Nature editorial endorsing open source software for journal submissions. No mention of climate models, but it certainly seems to play in their insistence for reproducibility . The money quote: “Reproducibility becomes more difficult when results rely on software. The authors of the editorial argue that,…
