If you have $X to spend on reducing climate change, would it best be spent in the third world or in the first world?

One of your best options make be to help people in poor villages in developing countries get rid of stoves that spew soot that spurs global warming.

Like tiny heatabsorbing black sweaters, soot particles warm the air and melt the ice by absorbing the suns heat when they settle on glaciers. One recent study estimated that black carbon might account for as much as half of Arctic warming. While the particles tend to settle over time and do not have the global reach of greenhouse gases, they do travel, scientists now realize. Soot from India has been found in the Maldive Islands and on the Tibetan Plateau.1

Soot is spewed by old stoves only lingers for a few weeks, so its effects on global warming are temporary. Remove the stoves and you remove an immediate source of global warming. Beyond that soot causes a number of health problems, increasing the bang for your charitable buck.

The new stoves cost about $20 and use solar power or are more efficient. Soot is reduced by more than 90 percent.

While carbon dioxide may be the No. 1 contributor to rising global temperatures, scientists say, black carbon has emerged as an important No. money to developing countries to do this.

Do trees really reduce air pollution levels of VOCs, NO2 and other compounds in addition to reducing levels of CO2?

Trees lower levels of several pollutants:

Trees help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide, sneakers shoes online and nitrogen dioxide. Trees remove this air pollution by lowering air tem sneakers shoes online perature, through respiration, and by retaining particulates.1

The impact of trees can be significant:

There is up to a 60% reduction in street level particulates with trees. 2In one urban park 212 ha. tree cover was found to remove daily 48lbs. particulates, 9 lbs nitrogen dioxide, 6 lbs sulfur dioxide, and 2 lb carbon monoxide $136/day value based upon pollution control technology and 100 lbs of carbon. 2One sugar maple 12 DBH along a roadway removes in one growing season 60mg cadmium, 140 mg chromium, 820 mg nickel, and 5200 mg lead from the environment. 2Air quality improvement in New York City due to pollution removal by trees during daytime of the inleaf season averaged 0.47% for particulate matter, 0.45% for ozone, 0.43% for sulfur dioxide, 0.30% for nitrogen dioxide, and 0.002% for carbon monoxide. Air quality improves with increased percent tree cover and decreased mixinglayer heights. moreLoading.

What are the health risks to an adult of living within a halfmile of a freeway?

Well half a mile is not right next to the freeway. They have done studies on living right next to the freeway. That caused brain damage in mice.

Here is the data:

Scientists have for the first time directly linked freeway vehicle emissions with brain damage. Scientists used a new technique that involved trapping airborne toxins along Los Angeles 110 Freeway, freezing them in water, and exposing lab mice to the toxins.

The researchers used a particle sampler to collect fresh ambient particulate matter along the CA110 Freeway near Los Angeles City for 30 days. After gathering grime on filters, they then soaked the filters in water for 30 minutes before freezing the watertoxin cocktail.

Frozen pollutants only remain chemically stable for around 3 months, so after collecting freeway toxins, the scientists brought the toxic ice cubed back to their lab soon after. They thawed the ice and released the toxins into the air breathed by their lab mice, exposing them to the fumes sneakers shoes online for a total of 150 hours over the course of 10 weeks.

The scientists then harvested the brain tissue of the mice, discovering through various cultures and tests that the mice brains resembled the brains of those suffering from memory loss or Alzheimers disease. For example, among other changes, specific receptors in the hippocampus had degenerated and parts of the cerebral cortex were inflamed.12 sneakers shoes online
