Portland, OR — Signs of Heavy Aerosol Nitrogen Deposition Contamination

Much of the landscape of Portland, Oregon is known to be burdened by dense amounts of nitrogen oxides, NO2 or NOX — all of which have negative effects on human, and plant, health.

The burning of fossil fuels are the main source of this aerosol nitrogen pollution. NOX is also a prime indicator of other “combustion-related pollutants”.

Since fossil fuel pollution also destroys our climate when it fills the global atmosphere, it also damages life in local and regional environments.

– For a fairly recent news article relating to a scientific study on this issue see: “PSU study shows Portland’s urban forest reduces air pollution but also finds hazards

Nitrogen is also a strong plant fertilizer which promotes growth. These photos show an incongruous growth of moss and lichen on exposed urban surfaces.

– Below is a small sample of photos which illustrate the degree of NOX pollution in Portland, OR. (More to come at a later date.)

Buffalo’s Climate Change Driven Mega Snow-Flood


Earlier this week something rather interesting and disturbing happened to the Jet Stream.

In the extreme northwest, a large heat pool over Alaska and the Beaufort Sea in the Arctic Ocean kept temperatures in the range of 10 to 36 degrees Fahrenheit above average. To the south, a powerful super typhoon, gorged on Pacific Ocean waters ranging from 1-2 C hotter than normal, raced into the extratropical region of the Central and Northern Pacific. And to the north and east, the cold core that normally resides over the North Pole began slipping south.

As the supertyphoon’s remnants hit the warm weakness in the Jet Stream near Alaska, it bombed…
