The Definition of Global Warming

The definition of global is said to be a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.

Statistics on Global Warming

Some statistics on global warming are that Global warming is among the most alarming environmental issues that the world faces today. It not only involves the significant rise in the earth’s temperature but a lot more. The adverse effects of global warming have become more and more apparent since the dawn of the 20th century, with more hurricanes and tropical storms causing massive destruction in different areas around the world, more animal species losing their habitats and becoming extinct, and more people dying because of too much heat. Some fact examples:

Globalization and Global Warming

Globalization has greatly increased around the world and the use of natural resources by industries. As a result, several environmental challenges have arisen, including water and air pollution, over fishing and loss of biodiversity. There's an increase in global output and increase profit, and industries are depleting the earthed natural resources. Such examples like whether damming a river for hydroelectric power, Mining for minerals and metals or drilling for oil. The effects of globalization are numerous. Corporations are often primarly concerned with cost efficiency and not environmentally.

Theories that Relate to Global Warming

Affects on Global Warming

Some impacts from increasing temperatures are already happening.

  • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
  • Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
  • Sea level rise became faster over the last century.
  • Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
  • Precipitation (rain and snowfall) has increased across the globe, on average.
  • Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees

This is what is happening economically.

What's happening health wise to people is:

  • Extreme heat. If high temperatures, especially when combined with high relative humidity, persist for several days (heat waves), and if nighttime temperatures do not drop, extreme heat can be a killer. Of all climate-related projections by scientists, rising temperatures are the most robust. Higher temperatures are also the most influenced by human behavior: the fewer heat-trapping emissions we release into the atmosphere, the cooler we can keep our planet. Because winter temperatures are rising faster than summer ones, cold-related deaths are likely to decline.
  • "Natural" disasters. Projected changes in temperature and precipitation under global warming are likely to lead to other effects that threaten human health and safety. For example, changing precipitation patterns and prolonged heat can create drought, which can cause forest and peat fires, putting residents and firefighters in danger. However, a warming atmosphere also holds more moisture, so the chance of extreme rainfall and flooding continues to rise in some regions with rain or snow. In many heavily populated areas, sea-level rise is more likely to put people in the path of storm surges and coastal flooding. Warmer ocean waters may spawn more intense tropical hurricanes and typhoons while ocean cycles continue to be a factor in the frequency of tropical cyclones.
  • Poor air quality. Three key ingredients—sunlight, warm air, and pollution from power plants and cars burning coal and gasoline—combine to produce ground-level ozone (smog), which humans experience as poor air quality. Higher air temperatures increase smog, if sunlight, fossil fuel pollution, and air currents remain the same.
  • Allergens and other nuisances. Warmer temperatures and higher concentrations of carbon dioxide in the atmosphere stimulate some plants to grow faster, mature earlier, or produce more potent allergens. Common allergens such as ragweed seem to respond particularly well to higher concentrations of CO2, as do pesky plants such as poison ivy. Allergy-related diseases rank among the most common and chronic illnesses that can lead to lower productivity.
  • Spreading diseases. Scientists expect a warmer world to bring changes in "disease vectors"—the mechanisms that spread some diseases. Insects previously stopped by cold winters are already moving to higher latitudes (toward the poles). Warmer oceans and other surface waters may also mean severe cholera outbreaks and harmful bacteria in certain types of seafood. Still, changes in land use and the ability of public health systems to respond make projecting the risk of vector-borne disease particularly difficult.

Global warming is not located in one specific area but all around the world. Every single country and person contributes to Global Warming
