Global warming!!

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?
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.

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.

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.


4. Can you quote another term for global warming?
There are another terms of the global warming, other early warning signs include melting glaciers, shifting ranges of plants and animals, and the earlier onset of spring.

5. Watch the video and explain this idea: Global warming: panic or reality?
In my opinion I think that it's reality because we can see our environment. It's catastrophe.The global warming is already under way. Also the society does nothing to prevent it. It's obvious that if we change this system we will have a worst results.

4 We can use renewable energies.
5.We can use public transport.
