Climate Change article

Answer 1

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Answer 2

Climate Change

- by Taylor

Human activities which have a significant impact on the climate are the burning of fossil fuels such as coal, oil and gas, whether in homes, factories, vehicles or in other ways.

Burning fuels releases carbon dioxide gas, a greenhouse gas, besides others. Since the early 1800s, when people began burning large amounts of coal and oil, the amount of carbon dioxide in the earth's atmosphere has increased by nearly 30%, and average global temperature appears to have rice and over by 1°C.

Such a temperature rise will cause changes in the amount and pattern of rain and snow, in the length of the growing seasons, in the frequency and severity of storms, and in the sea level. Farms, forests, plants and animals would also be affected. Humans also cannot escape the effects of this and hence should do their bit to save the environment.
