Answer 1

Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century, and in paleoclimateproxy records over thousands of years.

Answer 2

Global warming is a green house effect. Global warming is caused by the increasing amount of carbon dioxide. Nowadays, it is increasing day by day due to increasing pollution. It is caused by human beings only because they are using diesel and petrol vehicles which causes pollution which cause global warming. Due to this global warming only the temperature of Earth is increasing day by day which causes heat on earth. It's very bad thing for us that we all our doing the activities which results in a green house effect i.e. global warming. Global warming means "increasing heat in the world."It is the most effective green house effect. We can take an example like nowadays the temperature is very high as it is reached to 45 degree in Delhi, this is an effect of global warming only. We should reduce it by sharing vehicles with each other also reduces it. By planting more and more trees also result in reducing it.
