The most developed areas of the world contribute to increased global warming, since among China, the US and the European Union produce 50% of total carbon emissions. Droughts, floods and heat waves are the most common manifestations of climate change. In analyzing the relationship between armed conflicts and natural disasters caused by climate change it found that climate disasters are not direct triggers of wars in the world, but also facilitate the increased risk of violent conflict within the context of the ethnic, global warming has contributed to worsen the health of people around the world; Asthma is now the leading cause of hospital visits.
Climate change is due to natural causes caused by changes in energy received from the sun, the volcanic activity on the planet and the impact of human activity on burning fossil fuels and forests, altering the use of large tracts of land and logging that accelerate the greenhouse gases and global warming.
The most developed areas of the world contribute to increased global warming, as China, the United States and the European Union produce 50% of total carbon emissions with contributions from 25% China, 15% US and 10% the European Union. This information was presented in the framework of the G-7 where the richest countries aimed to reduce emissions of greenhouse gases in the world during this century.
Other pollutants countries include India, Russia, Japan, Brazil, Indonesia, Mexico, Iran, Canada and South Korea which contribute to 26% of total greenhouse gas emissions with contributions from 7% India 5% Russia, 3 % Japan and 2.4% Brazil. The rest of the no developed countries which constitute the vast majority, provide a whole only 24% of carbon emissions.
Droughts and floods are just some of the most popular affectations of climate change. These have led to extreme poverty of rural populations, migration of ethnic groups or rural workers to urban areas to survive, expropriation of rural land by large companies seeking basic resources such as water, wood, oil, etc. and it seems also relate to increased wars in the world. Climate disasters are not direct triggers of conflict, but also facilitate the increased risk of violent conflict within the context of the ethnic groups.
In his investigation by the Potsdam Institute for Climate Impact Research, Dr. Carl Schleussner explains that over 30 years has statistically analyzed the relationship between armed conflict and natural disasters caused by climate change. Globally there is a 9 percent overlap between armed conflict and natural disasters such as droughts and heat waves; but in countries with ethnic diversity, as in Africa, Central Asia and Latin America, it increased to 23 percent. Countries with greater ethnic diversity are more fractioned and are the hot spots of violent conflict.
Global warming has not only caused numerous environmental problems in various regions of the world, too, and according to a study released by the US government, has worsened the health of the world’s inhabitants. Under the new federal government report, global warming has increased air pollution, water and food, as well as propagates diseases associated with ticks and mosquitoes, allergies and thousands of deaths from heatwaves.
The head of the Environmental Protection Agency, Gina McCarthy, said that climate change has also come to affect the mental health of people: It is not just polar bears and melting ice caps. This is our families, for our future. Doctors were able to report quantify the number of pathways through which climate affects health. The worsening air pollution by power plants, pollen and even forest fires, are just some examples of the causes that have triggered the spread of diseases.
In fact, asthma is now the leading cause of hospital daily visits, mostly in times of heat that allergic and air pollution affect breathing difficulties. To reduce the high incidence of respiratory diseases and premature death, science adviser in the White House, John Holdren said preventable heat waves as long as emissions of greenhouse gases globally are reduced. This report was supported by more than 1 800 new scientific studies published and federal investigations, and was also reviewed by the National Academy of Sciences.
The global temperature of the planet is increasing rapidly since the nineteenth century, so reducing emissions of greenhouse gases is necessary to limit the duration and magnitude of climate change in the short and long term.
NASA has found that the temperature in the last 10 years has increased, they have been recorded in the XXI century higher temperatures. The average temperature of the earth’s surface has risen about 1 degree Celsius, a trend which is driven largely by increased carbon dioxide and other greenhouse gas emissions produced by the impact of human activity.
The greatest variation in the average global temperature is recorded north of the northern hemisphere causing the ice to the North Pole is becoming less extensive and thinner. Also in Antarctica increased average temperature but less register. Global warming also contributes to melting icecaps and causes lowest in the world coastal areas are flooded.
