One of the most significant international problems of the XXI century is a change of planetary climate. Of particular concern is the rapid overall growth in the number of cataclysms observed in recent decades. You’ll find out everything you wanted to know about this world problem.
Evidence of climate change
- Throughout the twentieth century, the Earth has experienced two trends of global warming.
- The last two decades of the XX century were the hottest decade in more than 400 years, and possibly leaders in temperature standards for several thousand years.
- Arctic ice sheets disappear very quickly, and scientists believe that the Arctic will begin to show its first ground covering in early 2040.
- In the period from 1961 to 1997, the world's glaciers lost 890 cubic kilometers of ice.
- The area of deserts worldwide increased by raising the temperature. At the end of 2007, Australia had lost 25% of the crop due to the desertification of land.
- Massive deforestation is the cause of 20% of the global warming resulting gas pollution by prohibiting the reabsorption of carbon dioxide.
- During the first Earth Day in 1970 to the new millennium, the greenhouse gas emissions caused by man has increased by 70%.
- According to the Agency's internal energy, the richest countries in the world over the next 25 years will invest about 20 trillion dollars in new research in energy, in hopes of slowing the effects of global warming.
- According to research by NASA, the average temperature worldwide has increased by 1.5 degrees since 1880, while taking into account most of the changes occurring in the last decade.
- The first forced relocation due to the effects of climate change took place in 2007 when 100 inhabitants of the Pacific islands were evacuated due to rising sea levels and subsequent flooding.
- Burning fossil fuels currently add about six billion tons of carbon dioxide into the atmosphere of our planet each year. Only half of these emissions processed using forests and oceans
Effects of climate change
The most visible consequence of climate change is not gradual warming. It wills "emergency situations" such as severe drought, floods, storms, hurricanes, an extremely hot day that will happen more often.
If greenhouse gas emissions are not controlled, the climate change will occur at a speed unknown since the beginning of civilization in the next hundred years.
Effects of climate change on humans
Climate and weather significantly affect the lives of people from the tropics to the Arctic. Although people adapt to the conditions where they live, and human physiology can handle substantial variation in weather, there are limits.
The significant short-term changes in weather can have serious effects on health:
- Excessive heat or cold can cause potentially fatal illnesses such as heat stroke or hypothermia, as well as increasing death rates from heart and respiratory diseases.
- Stagnant of the atmosphere may hold warm air and pollutants of air in the cities. This leads to the formation of smog that severely affects human health.
- Other extreme weather conditions such as torrential rains, floods, and hurricanes, also have severe impacts on health.
- In addition to changing weather patterns, climatic conditions affect diseases transmitted through water and diseases transmitted by vectors such as mosquitoes.
- Largely people's health depends on safe drinking water, sufficient food, secure shelter, and right social conditions.
- As a result only of diarrhea, malaria and protein-energy malnutrition in 2002 died more than 3.3 million people, with 29% of these deaths occurring in the African region.
Climate changes solutions
It is important to raise the awareness of society about the problems of the immediate future. All socially active people today need to take an active part in the unification and unity of the world community, ignoring all selfish, social, political, religious and other barriers that artificially divide people. Only by combining our efforts in the international community is not on paper, but in reality, you have time to prepare the majority of people in the world. We can solve the problem of climate and global economic shocks and changes that come.
Each of us can make a lot of good in this area! If people unite, they will do in ten times more, than they can do!
