Desertification

How global warming affect the desertification process is not 100% understood, but it is clear that an elevation in atmospheric and ground-level temperatures is likely to aggravate soil and vegetation loss in already hot climes. An increase in evapotranspiration and the decrease in rainfall mean that already semi-arid and sub-humid areas found across the world would face a future barrenness that is almost irreversible. This would negatively affect biodiversity and have a major impact on local human cultures and wildlife.

Devastating tsunamis

Global warming does not influence directly the formation of tsunamis, BUT they can be generated by events that are brought by an increase of the planet's temperature.An example is the melting of the ice sheets. Because they are extremely heavy and massive, glaciers apply a considerable amount of pressure to the Earth’s surface. This weight decreases as the glaciers diminish, resulting in a ‘freeing up’ of tectonic masses that can lead to huge earthquakes and significant volcanic activity, both of which are capable of creating deadly tsunamis. 

Migration, conflincts and wars

It is possible that future centuries could see increased friction between nations and ethnic group as decreasing resources lead to migration and conflict. Countries would seek to control the resources, provide safety and shelter for the citizens, with any cost. In the same time, previously populated places would become uninhabitable due to heat or other factors, displacing millions of people. These refugee hordes might be corralled into semi-permanent camps or even suffer because of unwelcoming native groups.  

 

More outbreaks of diseases

Maybe we do not realize, but warmer weather brings more diseases. Climate influences some of the most deadly diseases that are currently affecting millions of people worldwide. Some insects, such as mosquitoes are more prone to multiply even at small increases of temperature.

The climate change is set to engage the spread of Malaria, Dengue fever and West Nile to some parts of the globe that did not face such diseases before.The increased number of sick people could overwhelm public health services, especially in poor and unprepared countries. The Deadly Dozen is known to be a group of 12 diseases which have been identified as those most likely to spread due to global warming. It includes Plague, Ebola, Tuberculosis and Avian Flu.

Animal extinction and decreases in biodiversity

 

As the plant heats up, animals that are entirely dependent of cold environments will retreat to more northerly locations. The result is advancing to other eco-systems and displacement of animals from their natural habitat. Ultimately, a warmer climate will lead to the complete loss of polar-ice edge communities. Along with this, polar bears will have no longer were to live and the obvious consequence is for sure their extinction.


A strong relationship to oceanic warming, will conduct to declines in reproduction and increases in mortality rates among seals, sea lions and various seabirds. Acid rain is also known to have a negative influence. An example would be the death of large amounts of snails in areas that experiment acidic precipitation. There are several species of birds that eat snails because they are rich in calcium, but without a compatible replacement for this loss in their diet, these birds will lay eggs with a much higher chance of defective shells.

Harming the marine life

Oceans absorb approximately 30% of all carbon dioxide existent in the atmosphere, therefore, as more fossil fuel gets burned, ocean life will continue to be impacted negatively by the global warming. One critical change brought by climate change is the continuous reduction of phytoplankton. These are some small plants that serve as a food source for the entire ocean life, being responsible for almost half of the world's photosyntehic activity.

 Also ocean's warmer surface and acidification increase the danger to many marine species, such as  molluscs, coral reefs and crustaceans. Because coral reefs are so sensitive to higher temperatures, we can already observe that many have died due to global warming.

Some pollution facts

I decided to make a small parenthesis and give you some information on pollution, the main cause for global warming.
Recent studies show that 40% of global deaths occur annually due to water, air and soil contamination. If we look deeper into it, we would see that 3 million people die due to contaminated air and 2.7 million because of over-polluted water. Other 3.7 billion people are daily exposed at risk of diseases or are already infected with poisoned food.
If we analyze some of the globe's regions we would see that China is the world's top polluter, being responsible for 6.2 million tons of CO2 emissions per year. America comes up in the 2nd position, having 2.56 million tons of CO2 emission only from its power plants (the number is equivalent with 449 million cars). On the other extreme, is Africa, the lowest polluter, being connected only to 3% of the global emissions. Although it is not influencing as much as China or America, the continent still gets heavily impacted by the climate change because of its poverty, lack of medicine and technology.

What is "grashopper effect"?

Mainly, it is a consequence of global warming. It is a phenomenon that allows pollutants to travel from one ecosystem to another. Because of high temperatures, the toxic chemicals evaporate and ride the wind until they reach colder temperatures where they ultimately condense and fall down to the ground. This is why the antarctic region gets it the most.
As a result, both human ingest the toxins and develop various diseases.
I also attached a picture which hopefully will give you a better view over the grasshopper effect.
