Eerie photos of the smoky skies of Vancouver made the news — then disappeared after the air cleared. But the threat remains. Air pollution contributes to asthma, COPD and cardiovascular disease.
About 10, years ago, the last Ice Age had come to an end with carbon dioxide levels at an all time low. As the temperature had some drastic changes, rising from about negative 8 degress celcius to about one degree celcius, the carbon dioxide levels continued on its downward slope before slowly rising until recent years when it sky-rocketed.
Also, during the last era of warming aboutyears ago, the temperature had risen well above what we are experiencing now, yet the carbon dioxide levels were well below the average level ever recorded. Over the past century, the temperature has risen less than half of a degree even though the carbon dioxide levels are nearly twice the highest amount that have been recorded.
The current warming began about and will possibly continue for another years. Their findings are drawn from physical evidence of past climate cycles that have been documented by researchers around the world.
This is the side of global warming according to Avery and Singer, two scientists studying climate change. Their research was compiled from years of research on tree rings, ice cores, prehistoric villages, fossils, titanium profiles and numerous other sources.
The burning of fossil fuels by humans is most often the culprit of global warming but in Avery and Singers research they go on to say that the burning of fossil fuels has little effect on global warming and does not speed up the process.
In fact, studies show that humans burning fossil fuels actually account for aprox. Other sources are main contributors. These sources are volcanoes, trees, and even cosmic rays from space can greatly increase greenhouse gases.
New research involving ice core results allow us to distinguish which came first, temperature change or change in CO2 levels. Scientists from an organization called icecap concluded that temperature change actually preceded change in CO2 levels by over years. Merriam-webster For my quick resolutional analysis, I will state: Humans are the main cause of Pollution.
Through motor vehicle exhaust, the combustion of the fuel creates oxides of lead, nitrogen, and sulpher. The main causes are: Quick run through, oil spills etc.
Also the destruction of our environment falls into this category, such as the fact that every year we are losing 6 million hectares of land, loss of 24 billion tons of topsoil the soil that lets us grow foodloss of 15 million acres of prime farm land to mismanagement and overuse, etc Right now the best america can do is bury these deep underground in some bunker in nevada.
Because the water now has much more light absorbtion, increasing the temperature of the water.
This water heats up, and now we have melting polar ice caps. Just as an example we have the Ward Hunt Ice shelf that has been in solid condition for the past 3, years.
It started cracking in and now is currently in pieces. NASA When these break off, they start melting in the much warmer salt water and then raise the water level. And because there are less ice shelves, there is not as much sunlight being reflected back into space, rather more sunlight being absorbed.
The cycle just continues over and over.Air Pollution: Everything You Need to Know. Español; How smog, soot, greenhouse gases, and other top air pollutants are affecting the . Most forms of atmospheric pollution are harmful to human health as well as the environment at both urban and rural areas and this is because the activities that lead to pollutants being released into the air are carried out in both areas.
Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution—some visible, some invisible—that contribute to . Effect on Wildlife: Just like humans, animals also face some devastating affects of air pollution.
Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat. Depending on the type of air pollution, there is general consensus that exposure can cause chronic respiratory disease, lung cancer, heart disease, and damage to the brain, nerves, liver, or kidneys.
Continual exposure to most kinds of air pollution affects the lungs of growing children by scarring them at early stages of development. Air pollution in its most basic definition is the introduction of harmful substances into the Earth’s atmosphere.
These substances linger and cause many adverse effects. As you know, humans and other living creatures rely on the atmosphere for respiration.
