The effects of Global warming

As we can see that the main cause of global warming is the increase in greenhouse gases in the atmosphere and results in the increase of trapped sun rays.

The first effect of global warming is that it causes the ice to melt. The ice caps in the Antarctica are starting to crack and melt which causes an increase in sea level. As the sea level increase it is estimated that large cities such as Manhattan and cities in India will be underwater in approximately 40 years if the crisis isn’t control. It also increases floods the problem doesn’t stop there, because ice reflects the sun rays when it melts the sea water will absorb the rays and heat up. When it heats up it increases the vapor produced in the air and affects the sea life.

As the vapor in the air increases it increases wind viscosity that results in stronger hurricanes. One example is Hurricane Katrina which hit the US costal in 2005.It was considered one of the most disastrous Hurricanes that hit the US leaving thousands of deaths and thousands of houses broken down.

As the heat increases it affects the land by sucking all the moist from it. This causes the land to be dry and affects agriculture in which all the mineral required for tree will be lost. Not only that , it will also kill trees that have been grown for thousand of years where the land they take their nutrients from will be dry.

Finally, the heat increased the spread of infectious diseases such as malaria and bubonic plague. Insects such as mice, flies and mosquitoes increase when the heat increases because they perform warm places.
