23% of warming in Europe since 1980 due to cleaner air

Cleaner Air = More Sunshine = Warmer

“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.”

NASA Misleads About “Warming Hole” in SouthEast

NASA is telling lies about the southeast USA. They claim that sulphates were causing the Southeast to stay cooler and masking AGW. For some reason they use the term “warming hole”.

Read about it here.

How do they explain that it was warmer in the southeast in the 20s and 30s than now?

Here is the big lie that jumped out at me.

“As a response to the declining sulfate levels, Leibensperger’s modeling shows temperatures over the central and eastern United States have increased by 0.3°Celsius between 1980 and 2010.”

The trend from 1980 to 2010 (using NASA’s own data) is indeed .2C per decade.

But the trend from 1990 to 2010 is in fact negative.  It is -.2C per decade.

And the trend from 1895 to 2010 is FLAT!

Huge Increase in Sunshine Reaching Earth – 12.5 times the CO2 warming

The Hockey Schtick points to a new paper that finds a large increase in sunshine over the last 26 years.

“According to the authors, “the average increase of [surface solar radiation] from 1982 to 2008 is estimated to be 0.87 W m−2 per decade,” which equates to 2.26 W m-2 over the 26 year period. By way of comparison, this forcing was 12.5 times greater than the surface forcing alleged by the IPCC from increased CO2 over the same period.

The abstract is here. The paper is here.

“since the late 1980’s Rs has brightened over Europe due to decreases in aerosols but dimmed over China due to their increases. We found that variation of cloud cover determines Rs at a monthly scale but that aerosols determine the variability of Rs at a decadal time scale, in particular, over Europe and China.”

The warming since 1980 was caused by clean air legislation in the the US, UK and Europe.

Not by CO2.

I have posted several articles on this theme here , here and here.

Are we cooling the planet with SO2?

Today I am going to ask a provocative question. Are we cooling the planet with Sulfur Dioxide (SO2)?

Cooling you might say? I thought we were warming? It could be that we are keeping the planet 4C cooler than it would have been (and still appear to be warming).

Sulfur dioxide “is the chemical compound with the formula SO2. It is a toxic gas with a pungent, irritating smell, that is released by volcanoes and in various industrial processes. “

USGS: “The most significant climate impacts from volcanic injections into the stratosphere come from the conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. The aerosols increase the reflection of radiation from the Sun back into space, cooling the Earth’s lower atmosphere or troposphere. Several eruptions during the past century have caused a decline in the average temperature at the Earth’s surface of up to half a degree (Fahrenheit scale) for periods of one to three years. The climactic eruption of Mount Pinatubo on June 15, 1991, was one of the largest eruptions of the twentieth century and injected a 20-million ton (metric scale) sulfur dioxide cloud into the stratosphere at an altitude of more than 20 miles. “

From 1850 to 1980 SO2 emissions rose from almost 0 to 140,000 Gigagrams per year in 1980 and then dropped down to 110,000 Gigagrams around 2000 and then it started to rise again as China began to burn a lot more coal.

Illustration from Atmos. Chem. Phys., 11, 1101–1116, 2011 pg 1107 Anthropogenic sulfur dioxide emissions: 1850–2005 S. J. Smith1, J. van Aardenne2,*, Z. Klimont3, R. J. Andres4, A. Volke1, and S. Delgado Arias1

Pinatubo released 20 million metric tons of SO2 into the atmosphere.

20 million metric tons = 20,000 Gigagrams.

Therefore, around 1980, humans were releasing the equivalent of 7 Pinatubo’s worth of SO2 each year into the atmosphere.

Seven Pinatubo’s per year!

Depending on which reference, the cooling of one Pinatubo = .5F or .5C or even .6C.

That would mean human produced SO2 should be cooling the earth by about 3.5C.

Yet temperature went up over .5C from 1980 to 2000.

Oh wait, SO2 went down from 1980 to 2000 the equivalent of one Pinatubo.

Could it be that if there was no human SO2 in the atmosphere the temperature recovery from the Little Ice Age could have been as high as 4C instead of the .8C claimed?

Maybe all that coal China is burning is saving our planet!

(Yes I know low level SO2 is supposedly not as bad as SO2 at 30,000 feet, but high altitude SO2 also causes some stratospheric warming – look it up)
