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.

1. What is global warming?

Referees to average the Earth's temperature and became more hot. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. The global warming is caused by the pollution of the humans.

2. What is the process involved in the greenhouse effect?

Scientists are sure about the greenhouse effect. They know greenhouse make the Earth warmer by trapping energy in the atmosphere.
The greenhouse effect is the warming the temperature, caused when some gases of the atmosphere and change the temperature of the Earth. These gases let in light but keep heat from escaping.

3. What signs warn us about global warming?

The sun temperature is higher because there's more pollution and this make change
the oceans level and the ice of the Arctic are warning up.

4. Can you quote another term for global warming?

Greenhouse effect (nadvertent climate modification.)

5. Watch the video and explain this idea: Global warming: panic or reality? THE BIG QUESTION: What can we do to stop global warming?

The humans generate a lot of pollution every day. We must stop that to make a change in that fact and save our planet, because we're damaging our lives. We contaminate the air and also generate the greenhouse effect.
This is the reason of the fast average the Earth's temperature. We also should find a solution for remove that and create a better world. For example clean energies like the wind, the solar power and the water, use more the public transport...

ALL TOGETHER, WE CAN MAKE A CHANGE!!!
