Noctilucent Clouds Spread and Mystify

Wired has a feature on noctilucent clouds, once seen only at high latitudes but increasingly visible now lower down the globe. The clouds result from ice crystals at altitudes of 50 miles, higher than five 9s of the atmosphere. What water ice is doing up there, in a region 100 million times drier than the Sahara desert, is only one of the mysteries associated with the clouds. They are a recent phenomenon: the first scientific description of noctilucent clouds was penned in 1885. For a time it was believed that the clouds were an effect resulting from the eruption of the Krakatoa volcano two years before. Since 2002, the clouds have been sighted — and photographed — as far south as Oregon, Colorado, and Utah. Some scientists believe that human-caused climate change is playing a role, but others doubt this. Two satellites are in orbit to study the clouds; NASA's AIM generated this day-by-day movie of clouds in the vicinity of the North Pole during 2008.

      Now THAT is a theory I can get behind. I have been running scenarios through my mind to guess how and why the ice would get up that high and exclusively at the polar areas. It seems to me that the polar areas are the only places that are moving slowly enough to maintain the group of particles that had collected. As the particles approach the equator, the decision to escape of be captured by gravity become much more definite given the great slinging effect at those speeds. And if in fact the particles entered the atmosphere, they melted pretty quickly and if they were slung away, then they wouldn't remain amassed and wouldn't be visibly detectable as a cloud. (And if they used the gravity of the sun, they were probably propelled through time into the future or the past!)

      Isn't global warming what got us out of the ice age?

      It's probably better to say that global warming was the getting out of the ice age. The climate got warmer, wetter, and less icy. The problem is we really have no idea what drove that global warming -- other than it was not the accumulation of greenhouse gases.

      I honestly don't worry about slow temperature increases. Sudden temperature drops are another matter.

      I complete agree with that. Even the most ridiculous global warming scenario can't begin to compete with a scenario where an ice sheet covers almost all of North America and global precipitation is decreased by 90%... something that has happened in the past, as regular as clockwork.

      Here's the essay that I'm pretty certain "The Day After Tomorrow" is based on; it certainly predates it.

      http://thebear.org/essays2.html#anchor506010

      The biggest problem on the face of that theory is it says that the interglacial periods end because of a megastorm caused by certain conditions including "that the Earth be at or near perihelion...at the time of the northern winter solstice." Aside from the question of how that condition is going cause a megastorm, that condition happens on a 23,000 year cycle. A 23,000 year cycle is indeed contained in the ebbs and flows of glaciation, however, the interglacial periods (and the ends of interglacial periods and return of the glacial periods) happen on a 100,000 year cycle. The 100,000 year cycle corresponds to the change in the eccentricity in the earth's orbit... the one orbital parameter that should have the least impact upon the climate according to our (obviously flawed) understanding.

      The long and short of it is, we don't have enough historical weather and climate data to reliably predict future weather beyond about three days.

      Here's a fun experiment to try. First, go out and buy yourself a farmer's almanac. Then every day check the five-day weather forecast on the internet, and compare the fifth day out to what the almanac predicts for the same date. Then compare the actual weather to what was predicted five days ago and in the almanac. Keep track of how many times the five-day forecast calls the weather right, and the same for the almanac. My money's on there being no statistical difference in accuracy.

      Scientists can predict the future when a phenomenon is consistent over time. Eclipses, for example, are generally predicted very reliably, because the orbits don't change much.

      But weather and climate, on the other hand, change constantly. Trying to predict climate is like trying to predict fashion trends. Good luck with that. I'll be over here, not holding my breath waiting for the predictions to come true.

      Not to sidetrack this topic, but let's just get this out of the way...

      Rachel Carson never wanted to ban DDT. DDT has never been banned for use in fighting malaria.

      From the wikipedia page on DDT:

      In the 1970s and 1980s, agricultural use of DDT was banned in most developed countries. DDT was first banned in Hungary in 1968 then in Norway and Sweden in 1970 and the US in 1972, but was not banned in the United Kingdom until 1984. The use of DDT in vector control has not been banned, but it has been largely replaced by less persistent alternative insecticides.

      The Stockholm Convention, which entered into force in 2004, outlawed several persistent organic pollutants, and restricted the use of DDT to vector control. The Convention has been ratified by more than 160 countries and is endorsed by most environmental groups. Recognizing that a total elimination of DDT use in many malaria-prone countries is currently unfeasible because there are few affordable or effective alternatives, the public health use of DDT was exempted from the ban until alternatives are developed. The Malaria Foundation International states that "The outcome of the treaty is arguably better than the status quo going into the negotiations...For the first time, there is now an insecticide which is restricted to vector control only, meaning that the selection of resistant mosquitoes will be slower than before."

      Despite the worldwide ban on agricultural use of DDT, its use in this context continues in India, North Korea, and possibly elsewhere.

      Today, about 4-5,000 tonnes of DDT are used each year for vector control. In this context, DDT is applied to the inside walls of homes to kill or repel mosquitos entering the home. This intervention, called indoor residual spraying (IRS), greatly reduces environmental damage compared to the earlier widespread use of DDT in agriculture. It also reduces the risk of resistance to DDT. This use only requires a small fraction of that previously used in agriculture; for example, the amount of DDT that might have been used on 40 hectares (100 acres) of cotton during a typical growing season in the U.S. is estimated to be enough to treat roughly 1,700 homes.
