Global Warming is the increase in the average temperature of the atmosphere, oceans, and landmasses of Earth The planet has warmed (and cooled) many times during the 4.65 billion years of it history. At present Earth appears to be facing a rapid warming, which most scientists believe results at least in part from human activities. The chief cause of this warming is thought to be the burning of fossil fuels, such as coal, oil, and natural gas, which releases into the atmosphere carbon dioxide and other substances known as greenhouse gases.

Answer 1

**Part 1: Comprehension Questions**1. **What is global warming?**Global warming is the increase in the average temperature of the atmosphere, oceans, and landmasses of Earth.2. **What are the main causes of global warming?**The chief cause of global warming is thought to be the burning of fossil fuels (coal, oil, and natural gas). This releases carbon dioxide and other greenhouse gases into the atmosphere.3. **What are greenhouse gases?**Greenhouse gases are substances (like carbon dioxide) released into the atmosphere by the burning of fossil fuels. They act as insulators, trapping more of the sun's heat.4. **According to scientists, what will happen in 2100?**Scientists predict a further warming of 1.4 to 5.8 Celsius degrees (2.5 to 10.4 Fahrenheit degrees) by the year 2100. This will likely melt polar ice caps and glaciers, warm the oceans, raise sea levels (by an estimated 9 to 100 cm), and potentially damage food crops due to soil dryness in some regions.
