Could climate change could be the end of humanity?
Dictionary.com defines climate change as a “change in global or regional climate patterns, attributed to increased levels of carbon dioxide in the atmosphere. It is basically a change in climate due to human activity and sometimes non-human activities.”
According to Climate Change Communication, climate change is the defining issue of millennials in the 2000’s. The United Nations states, “from shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.”
History.com remarked that Greeks believed that humans could change temperatures and influence rainfall by chopping down trees, plowing fields or irrigating deserts. In the 1890’s Svante Arrhenius wrote, “By the influence of the increasing percentage of carbonic acid (C02) in the atmosphere, we may hope to enjoy ages with more equable and better climates. Especially as regards the colder regions of the earth.”
Reuters said, “If the temperature were to rise by 1.5°C, then adverse impacts of climate change will develop.” According to NASA, the potential future effects of global climate change include an increase in frequent wildfires, longer periods of drought in some regions, and duration and intensity of tropical storms.
According to The Guardian, there have been five mass extinctions caused by climate change, and another one know as the Anthropocene extinction could be coming. There is no set date to when this extinction will happen; scientists believe they can better predict after 2021. National Geographic states, “Global warming, global cooling, methane eruptions and anoxic events all contribute to mass extinctions. ”
Because of man-made forest fires and industrialized pollution the ocean ice-melting, an increase in CO2 levels causes poor air quality, which leads to health problems.
