TdS: GLOBAL WARMING. PANIC OR REALITY?

VISIT THE LINKS TO ANSWER THESE QUESTIONS:

1. What is global warming?

Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years.

We call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place. As the Earth spins each day, the new heat swirls with it, picking up moisture over the oceans, rising here, settling there. It's changing the rhythms of climate that all living things have come to rely upon.

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 warning?

Some of the most obvious signs of global warming are visible in the Arctic, where rising temperatures and melting ice are dramatically affecting 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, more extreme heat, shifting ranges of plants and animals, and the earlier onset of spring.
4. Can you quote another term for global warming?

Yes, the another term is greenhouse effect.

5. Watch the video and explain this idea: Global warming: panic or reality?

-I think that is a reality because our planet's temperature is rising and the poles are melt.

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