NASA finds something else climate models are missing…. forcing from ‘Secondary Organic Aerosols’

A new paper published by NASA by Tsigaridis and Kanakidou suggests that climate models have missed the forcing effects of organic aerosols, such as VOC’s from trees, oceans, and other sources that combine chemically in the atmosphere to create new compounds. Known as Secondary organic aerosols (SOA), they say “SOA forcing could exceed that of sulfate…

Study: Large volcanic eruptions cause drought in eastern China

Via AGU, and the “science is settled” department, once again we learn things we didn’t know about climate. In most cases, the annual East Asian Monsoon brings heavy rains and widespread flooding to southeast China and drought conditions to the northeast. At various points throughout history, however, large volcanic eruptions have upset the regular behavior…

The law of unintended climate consequences at work – study says 23% of warming in Europe since 1980 due to clean air laws

(Via the HockeySchtick) A paper published today in Geophysical Research Letters finds that clean air laws which greatly reduced sulfur dioxide emissions explain 81% of the “brightening” of sunshine and 23% of the surface warming in Europe since 1980. However, the authors note “this phenomenon is however hardly reproduced by global and regional climate models.”

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…

Oops! ‘Dieselification’ of London due to CO2 regulations have increased actual air pollution

London’s Dirty Secret: Pollution Worse Than Beijing’s Reader Drew H. submits this story. It’s the law of unintended consequences at work. European Union efforts to fight climate change favored diesel fuel over gasoline because it emits less carbon dioxide, or CO2. However, diesel’s contaminants have swamped benefits from measures that include a toll drivers pay…

Major enigma solved in atmospheric chemistry Nature: Researchers discover source of climate-active…

First time in 20 years – more daily record lows than daily highs that were either tied or set in 2013

2013 was a cool year in many ways. Most interestingly, the last year this split between highs and lows happened in the USA, in 1993, we had the eruption from Mt. Pinatubo the prior year which ejected so much aerosol into the atmosphere that it blocked sunlight and cooled the planet. Source: http://www.woodfortrees.org/plot/hadcrut4gl/from:1978 This year,…

Pollen has bigger influences on optical properties of the atmosphere than previously known

From Leibniz-Institut für Troposphärenforschung something that could be a possible negative feedback to CO2. As plants proliferate more due to increased CO2, it follows that pollen load in the atmosphere would also increase. Laser measurements show: pollen has considerable influence on air quality Leipzig, Germany. Pollen reflects more sunlight than previously known, and makes up…

Real pollution (not ‘carbon’ pollution) increases storm clouds

From the Pacific Northwest National Laboratory: A common theme among climate alarmists is that the wrongly named ‘carbon pollution’ aka carbon dioxide, increases the frequency and intensity of storms. Observational data show that NOT to be true,  and this new study shows why real pollution (aerosols) results in larger, deeper and longer lasting storm clouds, leading…
