But it Worked in the Simulation!

Perils of computer simulation of complex systems Story submitted by Ricky Seltzer John F. McGowan, Ph.D., writing on math-blog, describes the various ways in which breakthrough science can be misunderstood and miscalculated even by top-flight computer simulation.  (One example of breakthrough science, of course, would be climate modeling). Another important aspect, is that common-mode errors,…

Trees: sucking up the carbon

Higher density means world forests are capturing more carbon Forests in many regions are becoming larger carbon sinks thanks to higher density, U.S. and European researchers say in a new report. In Europe and North America, increased density significantly raised carbon storage despite little or no expansion of forest area, according to the study, led…

Warming 101 primer

Submitted by D.B. Stealey This article went viral when it was first published. Well worth reading: “Our planet has been slowly warming since last emerging from the “Little Ice Age” of the 17th century, often associated with the Maunder Minimum. Before that came the “Medieval Warm Period”, in which temperatures were about the same as…

Climate Modeling: “not always clear”

The previous story suggested that climate models predict with certainty “permanently hotter summers”. OK then, but in the same Eurekalert stream today, we have this release, where it seems they need to “prop up” the modeling, saying they “are not always clear”. How important are climate models for revealing the causes of environmental change? The…

Another bold forecast – destined for “climate FAIL”

Here’s the headline from the press release today, which will undoubtedly be regurgitated worldwide: Stanford climate scientists forecast permanently hotter summers Oh gee, where have wee seen this before? It’s another example of model madness, and it fits in with the now famous: Snowfalls are now just a thing of the past. Let’s compare expert…

Earth, fire, air, and water

Guest post by J Storrs Hall This is a reply and extension to Pat Frank’s “Earth Abides” post (sorry, couldn’t resist) which appeared here recently. The post features an intriguing interpretation of the temperature record to deduce climate sensitivity to CO2.  I thought I would try to recreate it and see where it took me. …
