Using the worksheet you completed in the activity portion of a lesson rank three issues that you believe to be the most serious threat in our environment as a result of global warming number one being the most used to explain it in a paragraph why you selected

Extreme weather conditions

Polar ice melting

Acidification of oceans

Explanation:

Global warming is a phenomenon that refers to increase in temperature of the earth surface as a result of the concentration in the amount of greenhouse gases in the atmosphere. Greenhouse gases like carbon dioxide, methane, water vapour in their normal amount helps to trap some part of solar radiation which is useful for all life on earth. If the proportion of these gases increase beyond normal, more radiation will be trapped and a surge in surface temperature results. This increase in temperature leads to:

Extreme weather conditions: Hurricanes, tornadoes becomes more prevalent as there is more heat in the atmosphere. Polar ice begins to melt as a result of increase in the temperature of the earth surface. Due to surge in the amount of carbon dioxide on the earth, the ocean dissolves the gases and this leads to the formation of weak carbonic acid.
