Solution

The correct option is A

2C


According to a temperature analysis conducted by scientists at NASA's Goddard Institute for Space Studies (GISS), the average global temperature over the last 18,000 years has risen approximatly by 2C. Though this may seem like a negligible change in the atmosphere, the impact it has had is huge. The major reasons behind this rise are increased industrial revolution and increased human activities such as the burning of fossil fuels, which have resulted in an increase in air pollutants. The most important greenhouse gases are carbon dioxide, methane, nitrous oxide and water vapour. While all these gases occur naturally in the atmosphere, their emissions from human sources has caused their levels to rise to a point that is no longer sustainable. This has resulted in an increase in global temperature.
