Climate Change

Climate change on a global scale, whether natural or due to human activity, can be initiated by processes that modify either the amount of energy absorbed from the Sun, or the amount of infrared energy emitted to space. In the last few decades or so, first global warming then climate change have been important topics of concerns regarding earth's environmental health. Scientists have been warning us for the past few decades that the Earth is gradually warming and a significant cause of that phenomenon is a result of human activities. Recently, results have been coming in after years of research confirming that the current warming of the Earth's climate is very likely to be due to human activities such as: greenhouse gases,  aerosols, and our operating power stations, which burn fossil fuels such as coal, natural gas or petroleum/oil to produce electricity. Our cars and manufactories are releasing CO2 and other heat-trapping emissions into the air, which act as a blanket, holding heat in our atmosphere and warming the planet. It's possible that many weather abnormalities across our planet are a consequence of this climate change.

Effects of global warming

Stanford-led study investigates how much climate change affects the risk of armed conflict

The Environmental Impact of Modern War

Warming trends are not the only concern. Scientists from Brown University and the University of Washington argue that the burning of fossil fuels has disrupted the nitrogen cycle by altering the amount of nitrogen in the biosphere. It has long been known that fossil fuel combustion releases nitric oxides into the air, which combines with other elements to form both smog and acid rain. But until now scientists have been unsure as to the extent nitric oxide emissions have affected the natural nitrogen cycle. In a study published in Science, researchers were able to trace nitrates to their source: nitric oxide produced by fossil fuels. They then examined two isotopes of nitrogen found in nitrates from a Greenland ice core. Recovered in 2006, the 100-meter-long core showed a record number of nitrates starting in 1718, corresponding with the beginning of the Industrial Revolution. So artificial changes in our atmosphere has been occuring at least since 1718, and can only have speeded up as our technology and population grew faster.

Coal Mining's Environmental Impact | From The Ashes

We are past the point of warning people and businesses/corporations; scientists and climatologists have the message out there about the dangers that are threatening all of us. However, a collection of media experts and special interest groups funded by fossil-fuel and related industries, are raising doubts about the truth of global warming. They are denying all the scientific findings and downplaying and distorting the evidence of climate change. They demand policies that allow industries to continue polluting, and attempt to undercut existing pollution standards. Corporate power is in denial; not caring about future generations because short-term profits are all that matters. The captains of industry are comfortable that nothing will happen during their time, so it's not their problem. For sure, each person can educate him/her self, and of course the efforts of each individual is important, but the biggest impact on climate change will come from large-scale changes, and well-reasoned international, national, and regional policies; thoughtful, systematic efforts to reduce polluting fossil fuel energy sources and unsound land use practices; and steady progress toward a green, sustainable future. "We are living in exceptional times. Scientists tell us that we have 10 years to change the way we live, avert the depletion of natural resources and the catastrophic evolution of the Earth's climate".

Very well done! Perhaps the project of a young student

Human Impact On The Environment

The 11th Hour is a documentary by Leila and Nadia Conners with narrative by Leonardo DeCaprio. It was well done and covered most of the facts and figures that scientists had released at the time.
