PPT-The Difference Between Global Warming and Ozone Depletion

Foreman Room 102 1 Global Warming and Ozone Depletion take place in two different layers of the atmosphere Global Warming Ozone Depletion Global Warming vs Ozone Depletion Causes Global Warming cars factories rice farming landfills . Stratospheric ozone: the natural cycle Produced in stratosphere by dissociation of oxygen atoms exposed to short-wave radiation Reaction accounts for most of adsorption of ultraviolet sunlight () as w Ozone Depletion. Quick recap…. ". The ozone layer. " refers to the ozone within stratosphere. over 90% of the earth's ozone resides. Ozone is an irritating, corrosive, colourless gas with a smell.

Warming?. Global warming is a when the earth’s temperature increases and it can change the earth’s climate permanently. Released greenhouse gases, increased amount of carbon dioxide, burning fossil fuels and human activities such as driving and cutting down trees and plants can cause global . EVSC 1300. Spring 2016.

What do you think Global Warming is?. Global warming is a key threat to biodiversity but few researchers have assessed the magnitude2climates calculated changes in habitatnumerous uncertainties in this approach we undertook a sensitivity Global surface temperature increased 0.74 ± 0.18 °C during the 100 years ending in 2005.The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in greenhouse gas concentrations"via an enhanced greenhouse effect. . Global warming is when the earth heats up and the temperature increases. More recently, the temperatures have been rising, causing more dangers for people, animals, plants and our environment..
