Realtime Maps of Global Pollutant Sources


The picture below shows in color the concentration of air pollution in North America.  The  lower US  seems to have three  notable pollution sources according to the color scale shown in the lower left of the photo. Roughly locating these three sources would be in California in the Western US, Chicago area in the Great  Lakes region, and Baltimore to Boston along the I 95 corridor. 

 Now for a look at Asia and the middle East.

According to these maps, the above one shows where most of the air pollution originates.

The following from the Science website is some information about these pictures.  While the text is from November last year, the picture map shows the situation in real time.  These are for July 16, 2017.

China’s air is notoriously toxic: Each year, it contributes to the premature deaths of some 1.6 million people. Concerned about how such pollution was affecting his family, Beijing-based data scientist Yann Boquillod founded AirVisual Earth, an online air pollution map that uses data from satellites and more than 8000 monitoring stations to display global air pollution in real time. The AirVisual Earth interactive maps prevailing wind patterns and shows color-coded concentrations of PM2.5—airborne particulate matter less than 2.5 microns in diameter that can penetrate deep into the lungs. Users can zoom in, tilt, and spin the globe for better viewing. The air pollution visualization was crafted “so people really understand how bad it is,” says Boquillod, who hopes an informed citizenry will pressure governments and communities to clear the air. AirVisual also delivers 3-day air pollution forecasts for 6000 cities to smartphones, and it recently began selling low-cost monitors people can use to track indoor and outdoor air pollution. “People want to share that data,” Boquillod says.

 

The pictures are screen captures. You will have to go to the Science site link here to move around the globe.

I am not a fan of the 2.5micron particles stuff.  Another study suggest that there is no evidence for it being considered a vehicle for killing massive numbers of people.  See Junk Science links to see why I say that.  This is a good map for chasing black carbon and other aerosols.

Did CO2 Cause North Korea’s Environment To Collapse?


Why is North Korea’s environment in a state of collapse? Well it is not due to global warming, global climate change weather weirding or what ever the new evasive title is. From the Public Broadcasting System (PBS) “Nova” program titled “Inside North Korea’s Environmental Collapse” we learn this:

“North Korea has been hiding something. Something beyond its prison camps, its nuclear facilities, its pervasive poverty, its aching famine, its lack of energy—electrical, fossil, or otherwise. What the hermit kingdom has been covering up is perhaps more fundamental than all of those: an environmental collapse so severe it could destabilize the entire country. Or at least, it was hiding it.”

What initiated the collapse? Nova had this to say:

“North Korea’s isolation means detailed data on environmental conditions are hard to come by. However, a 2004 study by the Korea Environment Institute based in Seoul, South Korea, reports that forest cover in North Korea dropped by 17 percent from the 1970s to the late 1990s. Following the collapse of the Soviet Union, which provided oil to its communist ally at a discounted “friendship price,” oil imports dropped by 60 percent. Unsurprisingly, the use of firewood for heating more than doubled.

“What resulted was an increasingly barren landscape. Even saplings are felled for fuel, stripping forests of their ability to regenerate. “They don’t have trees to hold the soil,” says Jinsuk Byun of Sookmyung Women’s University in Seoul. Byun was not a part of the recent delegation but has closely followed environmental conditions in the country. “When it rains the soil washes into the river, landslides occur and rivers flood. It triggers a really serious disaster.”

The Nova program cites loss of wildlife as follows:

” The lack of birds and other small animals noted by the scientists on their recent visit are a direct result of the famine in the 1990s, Demick says. “The frogs disappeared because everyone caught the frogs,” Demick says. “You see many fewer birds and small animals in North Korea than other countries. People living near the sea ate seaweed but that also ran out.”

Energy to heat homes. Energy to provide light . Energy to power the equipment to farm and do other forms of manufacturing.   The supply of fossil fuels is not sufficient to support the North Korean population.  This is a lesson for those who believe the world can manage without the use of fossil fuels.  Someday, perhaps it will, but alternative forms of energy–wind farm, solar cells and biofuels  are not ready for prime time, so be careful for what you wish.

In this case the North Korea leaders, present and past, are just plain crazy—- imposing a dictatorship that controls all aspects of the lives of the people. As the North Koreans are the same people as their cousins in South Korea, one would expect if the government quit regulating every aspect of their lives, they might be able to restore North Korea. Open up the country and spend the countries money on fossil fuels (energy) and stop spending it on nukes.

Now For Something Entirely Different


VOX.com has a page with “40 maps that explain the universe”. Photos and drawing plus text are there for your review. Some of the illustrations are really eye catching. For example:

Even a single comet is pretty darn big

This is the comet 67P/C-G — which the Philae probe landed on in November 2014 — superimposed on Los Angeles. In terms of space, the comet is absolutely tiny: just 3.5 miles wide.

NASA Satellite:Highest Levels Of CO2 In Southern Hemisphere


A new NASA satellite finds the highest levels of atmospheric CO2 in the Southern Hemisphere. One would have expected the highest levels over the Northern Hemisphere where the highest concentration of fossil fuel use occurs. This result is the first publication of the satellite’s measurements so it may be an anomaly.

NASA provided the following “Average CO2 Concentration Oct 1 to Nov. 11, 2014” chart:

OCO-2image2Note the scale on the bottom of the chart, that ranges from 387 to 402.5 ppm atmospheric CO2. As you can see the more red the coloring on the chart the higher the CO2 level. Roughly the red begins about 400 ppm. The reddest areas are over South America, Africa, Indonesia, China, the Northern Pacific East of Japan and the Southern Pacific East of Australia.

A Tour Of The International Space Station


International space stationimagesSuni Williams, the Commander of the International Space Station, takes you on a video tour.  The tour includes where they work, sleep, eat, and exercise.  The “orbital outhouse” use is explained.  EVA equipment is demonstrated.  This video was taken the day that Williams was returning to Earth in the Russian Soyuz vehicle.  Looks like working there is a great experience, but if you are claustrophobic don’t apply. Click here to take the tour.
