Lluís' portfolio 2 and 3

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? Is a temperature change of the world
2. What is the process involved in the greenhouse effect? Scientists are sure about the greenhouse effect. They know that greenhouse gases make the Earth warmer by trapping energy in the atmosphere.
3. What signs warn us about global warming?

• Melting glaciers, early snow melt and severe droughts will cause more dramatic water shortages in the American West.

• Rising sea levels will lead to coastal flooding on the Eastern seaboard, in Florida, and in other areas, such as the Gulf of Mexico.

• Warmer sea surface temperatures will fuel more intense hurricanes in the southeastern Atlantic and Gulf coasts.

• Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.

• Disruption of habitats such as coral reefs and alpine meadows could drive many plant and animal species to extinction.

4. Can you quote another term for global warming?
Yes, the pollution is a principal guilty of global warming. The people throw away bottles and then cause fire in the forest. The fire cause Co2 and the temperature of atmosphere up.
5. Watch the video and explain this idea: Global warming: panic or reality?
it's a reality because global warming is coming. The global warming produce inundations, the temperature ups and the poles melt.
