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…

Nature abhors a positive feedback

Negative Feedback Prevents Harmful Temperatures from Carbon Dioxide Guest essay by Bryce Johnson The purpose of the article is to contribute to refuting the false alarm that has been generated worldwide about excess global warming caused by atmospheric carbon dioxide, primarily by mischaracterizing its inherently negative feedback. Feedback is the effect that the result of…

New paper: man-made aerosols have had a net cooling effect since beginning of industrial revolution

More aerosols, means more clouds, which means cooler temperatures. Now that we are cleaning up aerosols worldwide, this may explain why the Earth is getting slightly warmer – more sunlight reaches the surface A paper published today in Science claims the transition from “pristine” to “slightly polluted” atmosphere at the beginning of the industrial revolution…
