    The Paris Climate Agreement Won't Change the Climate

    The governments of the world are ineffective when it come to dealing with climate change. Better, I think, to rely on the market to drive adaptation.

    Bjørn Lomborg takes an economic view of climate change. He accepts that man has an effect on climate change. His concern is setting priorities in a world full of major problems.

    Right, there are other pollution issues of more immediate concern.

    Climate change could cause stronger turbulence for airline passengers...


    Climate Change Could Cause More Turbulent Flights
    April 11, 2017 - Climate change could cause stronger turbulence for airline passengers, according to a new study.
    Researchers at the University of Reading in England say “turbulence strong enough to catapult unbuckled passengers and crew around the aircraft cabin” could become two or three times more common. “For most passengers, light turbulence is nothing more than an annoying inconvenience that reduces their comfort levels, but for nervous fliers even light turbulence can be distressing,” said Paul Williams, who conducted the research. “However, even the most seasoned frequent fliers may be alarmed at the prospect of a 149 percent increase in severe turbulence, which frequently hospitalizes air travelers and flight attendants around the world.”



    A new study suggests turbulence on flights could increase becuase of climate change.



    Specifically, researchers used supercomputer models to look at how wintertime transatlantic clear-air turbulence at an altitude of 12 kilometers will change when there is twice as much carbon dioxide in the atmosphere, which could happen by the end of this century.


    The models show light turbulence could increase by 59 percent, light-to-moderate turbulence could jump by 75 percent, moderate-to-severe turbulence could rise by 127 percent and severe turbulence could bounce a whopping 149 percent.


    The reason, according to the researchers is that climate change “is generating stronger wind shears in the jet stream.” “Our new study paints the most detailed picture yet of how aircraft turbulence will respond to climate change,” said Williams. The study is published in the journal Advances in Atmospheric Sciences.

    [b]Scientists Link El Nino to Increase in Cholera in Eastern Africa
    April 10, 2017 - Researchers are reporting a link between a climate phenomenon know as El Nino and the number of cholera cases in eastern Africa. Predicting when there’s going to be an El Nino event could improve public health preparedness.
    El Ninos are a global climate phenomenon that occurs at irregular times, approximately every two to seven years. During an El Nino, surface ocean temperatures in the eastern Pacific off the coast of South America become warmer than usual. The warming trend begins around Christmas time. The following year, in the fall, sea surface temperatures also warm, if somewhat less, in the western Pacific, leading to extreme weather events like flooding and droughts, conditions that are ripe for cholera outbreaks. Approximately 177 million people reside in areas where the incidence of cholera increases during El Nino. But there’s been scant evidence of El Nino’s health impact in Africa.


    A study published in the Proceedings of the National Academy of Sciences found the incidence of cholera increased in countries in East Africa. “Because they can either lead to surface flooding that washes contamination into drinking water in areas where there’s open defecation," said epidemiologist Sean Moore, who led the study. "It also can lead to overflowing of sewer systems in urban areas which again can lead to contamination of drinking water.” There are approximately 150,000 cases of cholera per year, mostly in sub-Saharan Africa, according to Moore, an epidemiologist at Johns Hopkins School of Public Health in Baltimore.



    Relatives of Samual Moro, 30, grieve after he died of cholera, outside the cholera isolation ward at the Juba Teaching Hospital in the capital Juba, South Sudan.



    But during El Ninos, researchers found the incidence swelled by some 50,000 cholera cases in eastern Africa, although the overall number of cases on the continent did not change — for reasons that are not completely understood, said Moore. Patterns of shift in the number of cholera cases were measured during El Ninos between the years 2000 and 2014. There also were 30,000 fewer cases reported in southern Africa during El Nino years compared to non-El Nino years, researchers found.. Scientists also saw a slight increase in the number of cholera cases in areas hit by drought due to El Nino. Moore said that’s because when water becomes scarce, available drinking water can become contaminated by bacteria in human waste.


    Without treatment, mortality rates from cholera can climb as high as 50 percent. To the extent that the climate phenomenon can be predicted six to 12 months ahead of time, Moore said public health officials can prepare for outbreaks, which tend to occur early on. “An advance warning could, even if it doesn’t prevent outbreak, it could at least prevent the deaths that tend to occur during the early part of an outbreak,” he said. With oral rehydration therapy, Moore said the risk of death from cholera drops to 1 percent. He said there are now cheap cholera vaccines that could be used to prevent the disease when it’s known that an area is going to be hit by an El Nino.

    Oman's mountains may hold clues for reversing climate change
    Apr 13, 2017 - Deep in the jagged red mountains of Oman, geologists are searching for an efficient and cheap way to remove carbon dioxide from the air and oceans — and perhaps begin to reverse climate change.
    They are coring samples from one of the world's only exposed sections of the Earth's mantle to uncover how a spontaneous natural process millions of years ago transformed carbon dioxide into limestone and marble. As the world mobilizes to confront climate change, the main focus has been on reducing emissions through fuel efficient cars and cleaner power plants. But some researchers are also testing ways to remove or recycle carbon already in the seas and sky.

    The Hellisheidi geothermal plant in Iceland injects carbon into volcanic rock. At the massive Sinopec fertilizer plant in China, carbon is filtered and reused as fuel. In all, 16 industrial projects currently capture and store around 27 million tons of carbon, according to the International Energy Agency. That's less than 0.1 percent of global emissions — human activity is estimated to pump about 40 billion tons a year into the atmosphere — but the technology has shown promise. "Any one technique is not guaranteed to succeed," said Stuart Haszeldine, a geology professor at the University of Edinburgh who serves on a U.N. climate body studying how to reduce atmospheric carbon. "If we're interested as a species, we've got to try a lot harder and do a lot more and a lot of different actions," he said.


    Travertine pools with white films of carbon fused with calcium

    One such action is underway in the al-Hajjar Mountains of Oman, in a quiet corner of the Arabian Peninsula, where a unique rock formation pulls carbon out of thin air. Peter Kelemen, a 61-year-old geochemist at Columbia University's Lamont-Doherty Earth Observatory, has been exploring Oman's hills for nearly three decades. "You can walk down these beautiful canyons and basically descend 20 kilometers (12 miles) into the earth's interior," he said. The sultanate boasts the largest exposed sections of the Earth's mantle, thrust up by plate tectonics millions of years ago. The mantle contains peridotite, a rock that reacts with the carbon in air and water to form marble and limestone. "Every single magnesium atom in these rocks has made friends with the carbon dioxide to form solid limestone, magnesium carbonate, plus quartz," he said as he patted a rust-colored boulder in the Wadi Mansah valley. "There's about a billion tons of CO2 in this mountain," he said, pointing off to the east.

    Rain and springs pull carbon from the exposed mantle to form stalactites and stalagmites in mountain caves. Natural pools develop surface scum of white carbonate. Scratch off this thin white film, Kelemen said, and it'll grow back in a day. "For a geologist this is supersonic," he said. He and a team of 40 scientists have formed the Oman Drilling Project in order to better understand how that process works and whether it could be used to scrub the earth's carbon-laden atmosphere. The $3.5 million project has support from across the globe, including NASA. Carbon dioxide is the primary greenhouse gas driving climate change, which threatens political instability, severe weather and food insecurity worldwide, according to the United Nations climate body.

    The reason for the expected turbulence was not given. The theory is that warmer oceans will reduce the Walker Circulation pump, increasing the wind speed differential between the jet streams and the atmosphere below. This is, of course, predicated on the theory that anthropogenic CO2 is warming the oceans and will continue to do so. Given the known properties of CO2 -- that only 4% if human caused, mostly coming from the carbon uptake cycle (oceanic), that CO2 is more of a lagging than a leading indicator with regard to climate change, and (among many other reasons) that its purported relationship to warming is logarithmic, with diminishing added effect per quantum increase -- pose greatly troubling challenges to the AGW theory, and even more so toward the prediction of a climate catastrophe. In reality, we can no more model climate than we can explain the universe, and may never be able to do so.

    Isn't it fascinating that the Holy Bible stated exactly what you said, 2000 years ago. Science, facts, truth, are beyond man's ability to understand. Yes, we've made great strides. No, nobody is saying, or has ever said, that we should not try, though atheists try to put these words into the mouths of Christians. But could a universe this complex, eternally beyond our comprehension and understanding, really have fabricated itself, from nothing?

    That is merely a rhetorical question.

    You ask far too many of those my friend. Facts and science are NEVER "rhetorical"

    Science 'facts' of the day are often wrong.
