Global warming


Panic or reality?

Global warming is already under way. The evidence is vast and the urgency of taking action becomes clearer with every new scientific study. Some of the most obvious signs are visible in the Arctic, where rising temperatures and melting ice are dramatically changing the region’s unique landscapes and wildlife—as well as people’s lives and livelihoods. Across the globe, other early warning signs include melting glaciers, shifting ranges of plants and animals, and the earlier onset of spring.

VISIT THE LINKS TO ANSWER THESE QUESTIONS:

1. What is global warming? rising temperatures and melting ice are dramatically changing the region’s unique landscapes and wildlife—as well as people’s lives and livelihoods.
2. What is the process involved in the greenhouse effect? is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse.First, sunlight shines onto the Earth's surface, where it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.
3. What signs warn us about global warming?Emissions from power plants, transportation, manufacturing, heating and other fossil fuel uses are estimated to have climbed to a record 30.6 Gigatonnes (Gt), said the IEA. F
4. Can you quote another term for global warming? No I can't!
5. Watch the video and explain this idea: Global warming: panic or reality?

THE BIG QUESTION:
What can we do to stop global warming? Suggest five ideas.

I think we can do much, removing industrial plants, since the energy We need to do something but some. And look not pollute much. as not to throw objects or food ... the ground.
