we have made the air so bad that it stinks, and traps heat in the atmosphere causing a climate crisis.
when was the last time you had a breath of fresh air? What's causing the smell in your local area?
"If we can't breathe the air then we die, if we can't grow food on it then we die, if we can't drink the water then we die."
humans need oxygen O2 at nose level to live. The good news is that trees capture carbon dioxide in the atmosphere and produce oxygen.
AQI air quality index - ozone and particle pollution
levels of air pollution. the indices used to measure air quality are: ground level ozone, particulate matter (pm2.5 and pm10), carbon monoxide, sulphur dioxide and nitrogen dioxide.

what is the greenhouse effect?
global warming is the result of the greenhouse effect which is the way in which heat is trapped close to the Earth's surface by greenhouse gases ghg in the atmosphere.
the sun's light passes through the atmosphere and heats the ground. The infrared rays radiate from the ground and cannot pass through the ghg layer and are reflected back to the Earth heating the atmosphere.
particulate matter PM2.5
ghg comes primarily from burning fossil fuels for energy use. Exhaust emissions from transportation is leading cause of smog. Smoke is toxic air filled with particulates. Sources of fine particulates, particulate matter, PM2.5, are any type of common combustion including power plants, car and truck exhaust, restaurant grilling and wood burning, grocery store food production, grilling, wood burning, residential wood burning, BBQ open-air wood burning, and fast food charbroiling.
transportation and power
New data released by the EPA on Friday, Feb12 2021, show that while emissions from the power sector continue to fall it remains the nation's 2nd largest source of greenhouse gas pollution. The biggest source, transportation, has continued to climb.
it's us, it's bad, and we can fix it
the relationship of long-term air pollution and COVID-19 indicate adverse health impacts that make people prone to the infection. Extended exposure to severely polluted air can cause chronic lung inflammation which could leave people more vulnerable to the coronavirus.
PM2.5 <2.5 microns
soot, tiny airborne particles, fine particulate matter PM2.5, are fine particulates less than 2.5 microns in diameter, 1/30th the width of a human hair, that lodge deeply into the lungs and pass through to the bloodstream, causing serious health affects such as respiratory illness, asthma, lung disease and heart disease.
long-term exposure to polluted air has increased the risks of heart and respiratory illness, including covid-19.
the current national standards limit annual concentrations of soot and other chemicals to 12 micrograms per cubic meter of air. Emissions on specific days are allowed to be as high as 35 per cubic meter, a standard set 14 years ago. These fine particles, which measure less than 2.5 micrometers in diameter, or one-thirtieth the width of a human hair, can enter the lungs and bloodstream, causing inflammation that can lead to asthma, heart attacks and other illnesses. Soot comes from a variety of sources such as industrial operations, incinerators, car and truck exhaust, power plants, smokestacks and burning wood.
long-term exposure to polluted air has increased the risk to heart and respiratory illness, including covid-19.
The Trump admin scrapped limits on methane leaks at oil and gas sites. Methane is a potent greenhouse gas a leading cause of air pollution related human illness and since it traps heat in the atmosphere it is the major contributor to global warming. Health and Human Services Department says that the rule could cause more ozone, and "ozone pollution exposure may be an important risk factor that increases susceptibility to and severity of infectious diseases, including COVID-19."
sources of fine particulates are any type of common combustion including power plants, car and truck exhaust, restaurant grilling and wood burning, grocery store food production, grilling, wood burning, residential wood burning, BBQ open-air wood burning, and fast food charbroiling.
are you still burning wood like a caveman?
danger of smoke. besides irritating the respiratory tract and the eyes, pollutants in the haze can cause serious long-term damage to health.
in Malaysia, because of the farming technique of clear-cutting the haze reached 208 on the Air Pollutants Index (API) in several districts. The clear-cutting causes wildfires which causes more and more smoke, which poisons more and more air.
global levels of carbon dioxide CO2 passed 400ppm, while 100ppm is considered an unhealthy amount of greenhouse gas (ghg).
air pollution can cause hypertension, diabetes and respiratory diseases, conditions that doctors are starting to link to higher mortality rates for covid-19.

we must ensure that air pollution standards protect the public's health. air pollution kills sciencemag.org
we can reduce air pollution by setting air quality standards, monitoring levels of air pollutants, and enforcing regulations. The goal is to reduce air pollution of fine particulates and noxious gases. The only way to get there is to immediately transition the global economy away from fossil fuels and into renewable energy, energy efficiency, and sustainable farming practices.
burning coal, oil, ngas is damaging the atmosphere
yes, the world needs energy, and we can use clean energy like solar and wind energy, instead of coal, oil, and methane-producing natural gas (ngas). Pollution from burning coal to make electricity is damaging the atmosphere. Leaks from oil production and transportation are damaging the oceans and rivers which is destroying our drinking water. Combusting fuel in cars and trucks is producing tailpipe emissions that react with sunlight to form smog which is causing the atmosphere to warm.
global levels of carbon dioxide CO2 passed 400ppm. Climate change is intensifying and the stability of the planet is at stake. Greenhouse gas emissions must be reduced by 80% by 2050.
parts per million by volume are the units of measure for the air quality standards for pollutants. 100ppm is considered an unhealthy amount of greenhouse gas (ghg). 350ppm is the safe upper limit. The earth's atmosphere hit 400ppm in March 2015, and 403ppm in 2017.
trees help to clean the air we breathe. Trees eat carbon dioxide CO2 and give oxygen O2 We have to breathe or else we die, immediately.

ghg CO2 and CH4
greenhouse gases ghg are noxious gases like carbon dioxide CO2 and methane CH4 that trap heat in the atmosphere. Heat in the atmosphere negatively affects the climate for human life. A 1°C rise in the temperature of the Earth is already causing storm surges, floods and wildfires.
carbon dioxide CO2 and methane CH4 are potent greenhouse gases that absorb the sun's heat, thus adversely warming the atmosphere.
methane is 30 times more potent than CO2 and is a major contributor to climate change. Methane is the main component of natural gas ngas.
methane is the primary component of natural gas, a common fuel source. The oil and gas industry produce industrial emissions of methane pollution. Methane is currently allowed to leak into the air in the fracking process, and 25% gets leaked into the atmosphere during distribution.
WHO (World Health Organization) has been campaigning to decrease toxic pollution around the globe, educating the public on the dangers to health. Its guidelines for PM2.5 is no more than 10 micrograms per cubic meter. ug/m3 is a measurement of density.
