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?
Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. 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. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
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.Scientists often use the term "climate change" instead of global warming. This is because as the Earth's average temperature climbs, winds and ocean currents move heat around the globe in ways that can cool some areas, warm others, and change the amount of rain and snow falling. As a result, the climate changes differently in different areas.
3. What signs warn us about global warming?
Change the climate, 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.
4. Can you quote another term for global warming?
Greenhouse effect.
5. Watch the video and explain this idea: Global warming: panic or reality?
-REALITY: because the planet is died. Everything will disappear someday... . The global warming killing of many animals and plants, until one day we kill us. We should try reduce pollution, recycle, use the transport public, etc.
THE BIG QUESTION: What can we do to stop global warming? Suggest five ideas
.-.Recycle.
-Save Electricity.
-Plant Trees.
-Solar Energy.
-Use bike, Bus, ....
-You shouldn't use cars.
