    Global warming Global warming Presentation Transcript

    • What is Global Warming ??? Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.
    • Some Gases Responsible for Global Warming :- Greenhouse gases are those that can absorb and emit infrared radiation, but not radiation in or near the visible spectrum. In order, the most abundant greenhouse gases in Earth's atmosphere are: 1.Water vapour (H2O) 2.Carbon dioxide (CO2) 3.Methane (CH4) 4.Nitrous Oxide (N2O) 5.Ozone (O3)
    • Effects Causing Global Warming 1. Global warming is the increase of Earth's average surface temperature due to greenhouse gases. 2. Sea levels rising are an effect of global warming an put many states at risk of existing in the near future. 3. Consequences of global warming include drought, severe hurricanes, massive fires, and melting of the polar caps. 4. Heat waves caused by global warming present greate risk of heat-related illness and death, most frequently among patients of diabetes who are elderly or very young.
    • Earth in @2050@...Greenhouse gases can stay in the atmosphere for an amount of years ranging from decades to hundreds and thousands of years. •. Spread of disease •Warmer waters and more hurricanes •Increased probability and intensity of droughts and heat waves •Economic consequences •Polar ice caps melting •. More floods •Fires and wildfires •Death by smog •Migration, conflict and wars •Loss of biodiversity and animal extinction •. Death of ocean life •Diminished food and water supplies
    • Don’t let these things
    • What can we do??? 1. Drive less 2. Recycle more 3. Avoid products with lot of packaging 4. Turn off electronic devices 5. Plant a tree 6. Spread the awareness
