Global Threats

The truth is clear. Our world gets warmer and our sea is sour. 97% of published climate scientists believe that global climate change is a reality and a result of human activity. By reducing the use of human fossil fuels, we can control carbon dioxide emissions (CO 2), slow the pace of climate change, and make coral reefs an important moment for adaptation.

Sea level rise: When the earth warms, the glacier melts and the sea level rises. Therefore corals become deeper in water, are less susceptible to sunlight, and are expected to grow more slowly. The Intergovernmental Panel on Climate Change (IPCC) found that the sea level is rising at an annual rate of 0.12 inches - 60% faster than predicted for 2007 of 0.08 inches.

Strong storm: Another predicted impact of climate change is the increase in frequency and intensity of tropical wind storms. Hurricanes, cyclones, typhoons get speed and strength from warm sea temperatures. These storms break coral branches and create larger, more powerful waves to overthrow the corals. The troublesome thing is that the heavy rain caused by storms leads to an increase in the amount of runoff from the land source, which leads to an increase in nutrients and sediments.

Since the beginning of the industrial revolution 150 years ago, the amount of carbon dioxide (CO2) in the air has increased by one-third. Approximately 25% of the carbon dioxide emitted is absorbed by the sea, 25% is absorbed by plants and trees, the remaining 50% is left in the atmosphere. As the oceans absorb carbon dioxide, their chemical changes become more acidic. This makes it difficult for corals and other marine organisms to grow their bones and shells. The calcification rate of coral and other coral reef organisms is beginning to decline. As carbon dioxide in water increases, corals can form weaker bones and are more vulnerable to storm disease and destruction.

Consumption of the ozone layer is mainly due to chlorofluorocarbon (CFC), which is an ozone-depleting substance, released into the atmosphere. Gases that trap heat, such as carbon dioxide (CO2), exacerbate this situation by creating atmospheric conditions that cause loss of ozone. When the protective ozone is depleted, the intensity and nature of ultraviolet (UV) reaching the surface of the earth increases. Although corals have natural sunscreen to protect themselves from ultraviolet rays, the level increases and this radiation can damage shallow corals.

Climate change is a serious global threat - agriculture and food production are the main cause of this threat and greenhouse gas emissions. Although the estimate varies, the Advisory Group on International Agricultural Research found that one-third of the greenhouse gas emissions come from agriculture and food production, agricultural production and food production occupy the "largest proportion" of emissions We reported that. The UN Food and Agriculture Organization has reported that there is a possibility that it will increase significantly in the near future unless it tries to reduce these greenhouse gas emissions.

The official name of the report is related to global warming at 1.5 ° C, IPCC special report on the impact of global warming on the level before the Industrial Revolution of 1.5 ° C, and related to strengthen global response to threats Global warming gas emission route Efforts to develop and eradicate poverty. "One of the important messages that is strongly reflected in this report was the influence of more extreme weather, sea level rise, a decline in the Arctic Ocean, and other 1 ° C changes in the cause of global warming "Co-Chair of the IPCC Working Group I

The threat of global war has intensified in television broadcasting and draws a picture of intense conflict between countries. The threat of global warming, the problem of extensive pollution, the epidemic of drugs in the United States, and the harmful effects of diseases such as cancer, diabetes, Alzheimer's disease. The gap between wealthy people and the poor continues to expand and it is difficult to keep up with living standards. Technology stole the hearts and thoughts of many people, except to get them from the human relationships and the community they care about. Mental illness affects one out of every five Americans. Yes, these are dangerous. Or are they?
