Transcript of global warming & greenhouse gases

global warming & greenhouse gases
How is global warming linked to extreme weather?
Scientists agree that the earth’s rising temperatures are fueling longer and hotter heat waves, more frequent droughts, heavier rainfall, and more powerful hurricanes.
What causes global warming?
Certain gases in the atmosphere block heat from escaping.

The Arctic is one of the worst places to be effected by global warming.
effects of global warming
• Allergies, asthma, and infectious disease outbreaks
• Disruption of habitats
• Rising sea levels
• Melting glaciers
What is global warming?
Global warming is the rise in temperature of the earth's atmosphere.

It's said that by the time a baby born today is 80 years old, the world will be 6 and a half degrees warmer than it is now.
The earth’s ocean temperatures are getting warmer, too—which means that tropical storms can pick up more energy.
Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change.

sources of CO2 emission
The greenhouse effect is the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
