Problems With Analyzing Governed Systems

Guest Post by Willis Eschenbach I’ve been ruminating on the continuing misunderstanding of my position that a governor is fundamentally different from simple feedback. People say things like “A governor is just a kind of feedback”. Well, yes, that’s true, and it is also true that a human being is “just a bag full of organic…

BOMBSHELL: Study shows greenhouse gas induced warming dropped for the past 14 years

Paper finds a decrease of IR radiation from greenhouse gases over past 14 years, contradicts expected increase – cloudiness blamed for difference. A paper published in the Journal of Climate finds from 800,000 observations a significant decrease in longwave infrared radiation from increasing greenhouse gases over the 14 year period 1996-2010 in the US Great…

Uncertainty in the dirt: another climate feedback loop

From the Carnegie Institution  Climate change and the soil Climate warming may not drive net losses of soil carbon from tropical forests Washington, DC — The planet’s soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a…

Study: irrigation causes ‘significant cooling of global average surface temperatures over land’

From the HockeySchtick: A paper published last week in Climate Dynamics finds man-made agricultural irrigation “causes significant cooling of global average surface air temperatures over land and dampens regional warming trends” by increasing cloud cover and precipitation. According to the authors, “irrigation, however, is typically not included in standard” climate models, and thus, “irrigation should…
