GLOBAL WARMING. Panic or reality?

VISIT THE LINKS TO ANSWER THESE QUESTIONS:

1. What is global warming? Global warming is the current rise in the average temperature of Earth's oceans and atmosphere. The scientific consensus is that global warming is occurring and was initiated by human activities, especially those that increase concentrations of greenhouse gases in the atmosphere, such as deforestation and burning of fossil fuels.

2. What is the process involved in the greenhouse effect? 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? 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.
4. Can you quote another term for global warming? It's a horribles mistakes, caused by the people, by us , But DON'T WORRY BECAUSE WE ONLY WE NEED IS CHANGE.
5. Watch the video and explain this idea: Global warming: panic or reality? I think that is a reality because we can see is starting to affect our planet. And because the people, we're destroying our world, with pollution, with our mistakes. I've realized that we need to change the world!
