1.El Nino
2Temperature variations in atmospheric layers
3.Skin cancer
4.Shifting of climate zones​

Answer 1

Skin Cancer is not an effect of global warming.

El Nino Effect:

• El Nino effect is a phenomenon in which the ocean gets heated up and as result, its temperature rises.
• Global warming contributes to the heating of the water.

Temperature variations in atmospheric layers:

• Global warming refers to the heating up of the Earth's surface due to human activities and solar radiation.
• This causes temperature variations in different layers of the atmosphere.

Skin Cancer:

• Skin cancer is caused due to exposure of skin to harmful UV radiations coming from the sun.
• The ozone layer protects us from these radiations but its recent depletion has caused an increase in cancer cases.
• Thus ozone depletion is the reason for skin cancer and not global warming.

Shifting of climate zones​

• The heating of the earth has resulted in the melting of glaciers.
• The temperature change along with flooding has caused a shift in climatic zones.
