Atmospheric conditions that change from hour to hour or day to day are an example of climate change.

Cows produce a very powerful greenhouse gas. 

Climate change can directly affect human health by increasing the occurrence of smog in cities such as Delhi. 

The Earth’s climate has remained more or less unchanged over its long history. 

The term ‘carbon emissions’ refers to the carbon dioxide released because of human activities. 

Globally, the processes involved in the production of energy cause the greatest emission of greenhouse gases.  

Carbon dioxide is the most abundantly produced greenhouse gas and is also the most powerful heat-trapper.
