The document discusses global warming and its causes and effects. It notes that global warming is being driven by greenhouse gas emissions from human activities like burning fossil fuels. This is causing average temperatures, especially in the Arctic, to rise faster than elsewhere. Some of the impacts of global warming mentioned include melting ice, rising sea levels, species moving to more northern or higher areas, and potential future issues like stronger storms, more floods and droughts, and less available fresh water. The document ultimately suggests actions can be taken to address global warming such as using biofuels and planting new forests.

1. Environment
Natural disasters. Global warming.

2. Aim.
• To introduce listeners with the global warming.
• To help get outside of causes of global warming.
• To train my English skill.

3. What does it mean?
• Environment –
it’s everything around us.

4. Natural disasters.
• Global warming
• Earthquakes
• Tornadoes
• Floods
• Hurricanes

5. Global warming in Arctica.
• Average temperatures in the Arctic region are rising twice as fast as they are
elsewhere in the world.
• Arctic sea ice has decreased 14% since the 1970s.
• Will develop floods.

6. Aral sea.
• Since 1960, the Aral Sea has: lost 50% of its surface area
• Central Asia has:
• lost its fishing industry and other supporting industries
• had an increase in public health problems
• decreased its agricultural production
• experienced changes in climate
(longer, colder winters and shorter, hotter summers)

7. Global warming. Causes.
• several greenhouse gases
• Most come from the combustion of fossil fuels in cars, factories and
electricity production.
• Some of them can even trap more heat than CO2.

8. Effects of global warming.
• Ice is melting worldwide
• Sea level rise became faster over the last century.
• Some butterflies, foxes, and alpine plants have moved farther north or to
higher, cooler areas.
• New types of animals and plans will be developed.

9. What can happen in future?
• Hurricanes and other storms are likely to become stronger.
• Floods and droughts will become more common.
• Less fresh water will be available.
• Ecosystems will change—some species will die, some will grow new.

10. What Can We Do?
• Use bio-machines
• Cutting forests, to plant new one to restore oxygen in the air.
