Most of the climate changes over the past 650000 years are attributed to global warming

Explanation:

Global Warming is the rise in the average temperature of the Earth's climate system over a time period. It leads to climate change.

Global warming is mainly caused by man, who by his actions causes an increase in the temperature on Earth.

The main way that he influences this phenomenon is, he is responsible for emission of greenhouse gases like  carbon di -oxide , methane and other gases.

This paves way for the sea level rising, Ice in Arctic regions melting, frequent extreme weather conditions.

In some areas there might be abundant rainfall and in other areas there might be drought.

The impact of global warming will be extinction of many species,  low crop yield.

Rising sea levels, will have an impact on people living in coastal areas.

So we have to do what we can to slow down the global warming and protect our environment and our Earth.
