b. Global climate is changing due to burning of fossil fuels and deforestation. - This is the most widely accepted theory concerning global climate change.
The emission of greenhouse gases has increased due to the burning of fossil fuels. Deforestation also plays a role in increasing one of the major greenhouse gas - carbon dioxide. Increase in the concentration of greenhouse gases traps the solar light in the atmosphere and the average temperature of the globe is increasing. Thus, the global climate is changing on account of burning fossil fuels and deforestation.
a. Changes in the global climate will lead to an increase in extreme weather and flooding.
The above statement is true. Changes in global weather will raise the temperature and the melting of polar ice will increase the mean sea level of the water bodies. This may result in flooding of low-lying areas.
However, this is the effect of global climate change.
c. Global climate change will happen rapidly.
Global climate change will happen gradually over time and not rapidly, as mentioned here.
d. Extra carbon dioxide and global warming will be beneficial.
Extra carbon dioxide and global warming will not be beneficial as the temperature rise and flooding will take place.
