Detailed explanation-1: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. Already the average global temperature has increased by 1C.

Detailed explanation-2: -Air temperatures on Earth have been rising since the Industrial Revolution. While natural variability plays some part, the preponderance of evidence indicates that human activities-particularly emissions of heat-trapping greenhouse gases-are mostly responsible for making our planet warmer.

Detailed explanation-3: -Earth’s temperature has risen by an average of 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, or about 2° F in total. The rate of warming since 1981 is more than twice as fast: 0.32° F (0.18° C) per decade.

Detailed explanation-4: -Answer. The rapid increase of human populations has left us battling with other species for limited resources, and the unmitigated burning of fossil fuels has now created a blanket of carbon dioxide around the world, which is slowly but surely increasing the average global temperature.

Detailed explanation-5: -The increase in greenhouse gases from the burning of fossil fuels, agricultural activities, and deforestation, which has caused global average air temperatures to increase.
