The document discusses several issues caused by climate change, including droughts and desert expansion, flooding, rising sea levels, changing ocean salinity levels, and rising sea temperatures. It notes that droughts will intensify and new areas will experience drought, deserts will expand as areas dry out, and flooding will increase due to climate shifts and more rainfall. Rising seas will submerge coastal lands and infrastructure and force population migration. Changing ocean salinity from melting glaciers will disrupt marine ecosystems and fishing economies. Rising sea temperatures will alter ocean currents and climate patterns on land and sea.

2. Droughts and spreading deserts Because of the global warming the climate is getting hotter and that leads to droughts. The droughts will be more intense than before and countries that never had droughts will in time have them. And the existing deserts will expand. All this will lead to the deserts spreading causing humans to move from their homes in lack of fresh water. Here follows the geographical, economic, political & social views of the problem.

5. The leaders of the countries with deserts and droughts have to work together to find a way of sharing the nearby rivers and the ground water. Otherwise there will be wars and even more misery. If we can’t make the deserts more habitable, the people in the deserts will move to another area or even another country. Causing a mass movement of refugees, which causes problems for the other countries. How should they help them, where should they live and is it enough living space on this planet?

7. Floodings When the snow in the mountains melt it will create a torrent running down the mountain causing floods and damage in the lower areas. Because of global warming the climate will shift towards a more tropical character. This leads to more rain causing floodings . Here follows some consequences of the problem:

8. Floodings When flooding hits a city the consequences will be fatal, people would have to be evacuated which would cost a lot of money. To rebuild the damage caused by the flooding and to ensure that those who need help, or medical treatment shall receive it in time. This will also cost a lot of money. People will also lose their belongings, homes and food shortages. This might even lead to starvation. Repeated flooding over large areas results in landscapes getting destroyed and makes it hard to live there.

9. Sea levels rising When the glaciers melt it will cause sea levels to rise. This affects the coastal areas in many countries. When the sea level raises the coastlines will decrease. Causing governments to drastically react to prevent the sea from destroying nations. Here follows the geographical, economic, political & social views of the problem.

12. Changing salintiy levels Glaciers are made up of freshwater. So when the glaciers melt large amounts of freshwater will go into the ocean. Since the oceans are mostly saltwater. This is causing a inbalance in salinity levels in the oceans. This affects all the creatures living in the water, they are created to live in salt water so when it’s too much freshwater in the oceans, they will die. The changes of salinity levels in the world’s oceans affect everything living in it, because salt water plants and fish will not be able to recondition them selves to survive in fresh water. The same goes the other way around. This leads to the following effects on;

14. Rising sea temperature One of the effects of global warming; rising sea temperature. When it rises the currents change which can lead to changes in the climate. Both on land and in the sea. Another effect of the rising sea temperature is that the ice will melt, causing cold water spreading in the oceans affecting currents as well . Here follows the geographical, economic, political & social views of the problem.
