1. What is global warming? What can its effects be? 2. What is greenhouse effect? Which gases are responsible for it?
Answers
Answer:
1) The globe is heating up. Both land and oceans are warmer now than they were when record keeping began, in 1880, and temperatures are still ticking upward. This rise in heat is global warming, in a nutshell.
Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few.
2) The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.The absorbed energy warms the atmosphere and the surface of the Earth.
carbon dioxide is responsible for it.
