Asia pollution blamed for halt in warming: study

Quote:
Smoke belching from Asia's rapidly growing economies is largely responsible for a halt in global warming in the decade after 1998 because of sulphur's cooling effect, even though greenhouse gas emissions soared, a U.S. study said on Monday.

The paper raised the prospect of more rapid, pent-up climate change when emerging economies eventually crack down on pollution.

World temperatures did not rise from 1998 to 2008, while manmade emissions of carbon dioxide from burning fossil fuel grew by nearly a third, various data show.

The researchers from Boston and Harvard Universities and Finland's University of Turku said pollution, and specifically sulphur emissions, from coal-fueled growth in Asia was responsible for the cooling effect.

Sulphur allows water drops or aerosols to form, creating hazy clouds which reflect sunlight back into space.

"Anthropogenic activities that warm and cool the planet largely cancel after 1998, which allows natural variables to play a more significant role," the paper said.

Natural cooling effects included a declining solar cycle after 2002, meaning the sun's output fell.

The study said that the halt in warming had fueled doubts about anthropogenic climate change, where scientists say manmade greenhouse gas emissions are heating the Earth.

"It has been unclear why global surface temperatures did not rise between 1998 and 2008," said the study published in the Proceedings of the National Academy of Sciences of the United States.
Either this will be the reason du jour or Al Gore will have these study scientists shot...

The followers on the global warming faith will just ignore this.

hhhmmm...maybe we should go back to using high sulpher coal back here in the USA...?...

Question Re: Asia pollution blamed for halt in warming: study

Arctic sea ice loss causin' China's 'airpocalypse'...

China's 'airpocalypse' linked to Arctic sea ice loss
Wed, 15 Mar 2017 - A deadly haze of air pollution over China in 2013 has been linked to the melting of Arctic sea ice.
Quote:
The air pollution that lingered over eastern China for nearly a month in 2013 has been linked to the loss of Arctic sea ice the previous autumn. A study says the haze lasted much longer because the melting ice and increased snowfall altered wind circulation patterns. If Arctic ice continues to shrink due to climate change, the scientists say similar events will likely recur. They argue that this could threaten the Beijing Winter Olympics set for 2022.

Emissions puzzle

Air quality issues have plagued China in recent years but the pollution experienced in January 2013 was significant because it lasted so long. The large-scale haze stayed in place for almost a month and around 70% of China's 74 major cities exceeded the daily air quality standard for very fine particulate matter, which poses serious risks to health. Scientists were puzzled by the event as the Chinese government had taken steps to curb emissions from coal fired power plants, one of the most significant contributors to air pollution.


Air pollution that lingered over eastern China in 2013 is being linked to changes in Arctic sea ice

Now researchers say that record Arctic sea ice decline in late 2012, plus extensive snowfall over Siberia disturbed wind patterns and produced stagnant air conditions over the east China plain. "In wintertime, in regions like Beijing you get these north west howling winds that blow like hell," said Prof Yuhang Wang from Georgia Tech University, one of the report's authors. "A ridge system controls the intensity and location of this cold air moving south so what happens when you put in sea ice forcing or snow forcing, the ridge system gets weaker and moves eastward - instead of cold air blowing in the eastern part of China, it went to Korea and Japan in January 2013."


A haze of air pollution hung over eastern China for around a month in 2013

The research team looked at ventilation conditions over the past 35 years and were able to show that the poor dispersal seen in 2013 was unique. They then looked at the climate related factors that might contribute to poor ventilation and their findings indicate that the loss of Arctic ice and snowfall over the forests of Eurasia were critical for the haze event. The researchers weren't able to separate the scale of the impacts between these two factors. What they are sure about is that in combination, they made the haze much worse. "You see evidence in the summer that the particulate matter is getting less, but you don't see a clear trend in the winter and what we believe is that the effort is being hammered by changes in the Polar region with ice and snow," said Prof Wang.

Angry Re: Asia pollution blamed for halt in warming: study

Chinese no longer willing to wait for solution to pollution problems...

Tensions rising as Chinese no longer willing to hold their breath on pollution problems
Monday 20th March, 2017 - Cracking down on dissent has been a hallmark of Chinese public life. But a population once ignorant of the toxic cost of pollution is speaking out against a government intent on growing the economy. The war on pollution has increased tensions across China, Nathan VanderKlippe reports.
Quote:
In the village dubbed the birthplace of Beijing’s smog, anger is rising into a sky that seems permanently darkened by pollution. At least three times over the past two years, local residents in Songting have gathered to protest at the gates of the steelworks that surround the place generations have called home. People here once farmed rice, peanuts and corn until, in the years before the Beijing Olympics, their fields were transformed into an industrial forest of pipes, stacks and production lines, after iron and steel companies moved away from the capital to leave behind cleaner air for the Games. Two-hundred kilometres east of Beijing, they erected a metallic forest of emissions towers that belch exhaust and soot. During one severe episode in February, the air grew so thick that residents could no longer see across their narrow streets and workers got lost on the way home.

Now the villagers are fed up. One of the recent steel-mill protests lasted more than a week. “Every day, more than 30 people gathered there,” said Zhao Xiuying, 54, who lives in an old village home that backs out onto a vista of metalworks. The villagers demanded pollution compensation, but received nothing. So they tried again. “We blocked the coking plant, too,” Ms. Zhao said. “But no one fixed our problem.”

Speaking out can be risky in China, where officials move quickly to crush efforts to organize dissent of any kind. But across China, a population once ignorant of the damage wrought by noxious air has gained a keen awareness of what they are breathing – and a growing unwillingness to accept it. “Before, people might have just endured. Now, that patience and endurance has worn out,” said Ma Jun, China’s best-known environmentalist. “We have seen more demands from people to solve the problem.” Stalled progress has made those demands grow more acute.

Until this winter, a raft of government measures set in place under a Chinese “war on pollution” had yielded annual improvements. Gradually, people were beginning to see more blue skies. But amid a slowing economy, a surge in steel production capacity has been accompanied by waves of thick air that have coated northern China this winter, while southern regions have also suffered unusually bad air. Air quality worsened in the area around Beijing throughout much of 2016, a trend that has continued this year. Average Beijing air quality in January was among the worst since 2009, the first full year air monitoring statistics are available. The city’s February air, on average, was 35 per cent more polluted this year than last.

AGW is climate change based on man's activities. It incorrectly assumed man was the cause of all global warming...; all of it.
Then honest Scientist challenged the Consensus with "FACTS.

So now it is "Climate Change." A convenient title as it will accommodate any dynamics of our climate, and they can still blame mankind.

This article, of course, it the height of Hypocrisy. Back when the very same set of experts were warning of a global ice age their suggestion was to "dirty" the exhaust of Jet engines so we would create a warmer environment. Which brings me to my pet issue on the whole AGW craziness.

Since it is clear we really don't know the true nature of the forcing's involved, perhaps mankind should be cautious about how we "solve" the Anthropogenicly invented problem.
