How have humans changed the atmosphere of the planet in 200 years?

Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

∙ 11y agoMostly our carbon dioxide emissions from burning fossil fuels, contribute to the 'greenhouse effect' by trapping heat energy inside Earth's biosphere. Gases such as methane, from cattle eructations (belches) and nitrous oxide from industry also contribute to global warming. Chlorofluorocarbons (CFCs from spray cans) affect the ozone layer, a helpful layer of the stratosphere which blocks the much of the harmful UV (ultraviolet) rays from the sun.

∙ 10y agothe burning of fossil fuels (oil, coal etc)
the increasing co2 emissions have slowly broken down the ozone layer and created a lot of global environmental issues, including rising sea levels and temperatures.

∙ 12y agoby creating carbon dioxide and monoxide(look in dictionary) which damages the o-zone layer which causes gobalwarming
Wiki User
∙ 11y agothe most obvious thing was converting the atmosphere from one dominated by carbon dioxide & hydrogen to one dominated by nitrogen & oxygen about 3 billion years ago.

Was cyanobacteria the first to exist or dinosaurs?
Cyanobacteria. Cyanobacteria are among the earliest forms of life and are thought to have evolved approximately 2.5 billion years ago. These bacteria are thought to have changed the atmosphere of the planet via nitrogen fixation. The first dinosaurs evolved approximately 250 million years ago during the late Triassic.

How has the atmosphere changed over the last 4.5 billion years?
Due to photosynthesising, single celled organisms, the atmosphere now has much more oxygen in it. this is possibly the most important change as with out we would exist. The atmosphere originally had much more carbon-dioxide and made the planet so hot humans would not be able to survive.
What are the chances of the Earth ending within 50 years?
Pretty high if humans keep on polluting the earth and causing the atmosphere to thin out, allowing dangerous radiation into out planet.

Why are humans concerned about removal of trees?
Because the atmosphere of the Earth is what it is largely as a result of millions of years of the existence of vast forests of trees and ... coincidentally and perhaps inconveniently ... humans depend on that atmosphere for breathing purposes.
