Question

Write note on Global Warming and climate changes.

Answer 1

The whole climate of the world is changing regularly because of the increasing global warming by the natural means and human activities. All the changes have an enormous impact on the people’s lives and ecosystems. The average global temperature has been raised by 1 degree in the last 30 years. It has been reported by the Intergovernmental Panel on Climate Change (IPCC) that average global temperature can be raised by 2 to 8.6 degrees F by 2100. The rate in increasing global temperature is because of the increasing emissions of heat-trapping gases called green house gases in the atmosphere.

Answer 2

Global Warming is the phenomenon in which all areas of the Earth’s surface are heating up or warming up. As this Warming-up phenomenon occurs across the Earth’s Globe, it is called ‘the Global Warming’

Climate change occurs when changes in Earth's climate system result in new weather patterns that last for at least a few decades, and maybe for millions of years. The climate system is comprised of five interacting parts, the atmosphere, hydrosphere, cryosphere, biosphere, and lithosphere. The climate system receives nearly all of its energy from the sun, with a relatively tiny amount from earth's interior.
