Sunlight passes through the atmosphere and warms the Earth’s surface. This heat is radiated back towards space. However, most of the outgoing heat is absorbed by greenhouse gasses and re-emitted in all directions, warming the surface of the Earth and the lower atmosphere. Human activities, such as the burning of fossil fuels, increasingly emit greenhouse gasses into the atmosphere. This leads to positive feedback loop, enhancing the warming of Earth’s surface. As more heat is re-emitted, sea ice melts. This, in turn, “exposes the underlying sea surface, which is darker and absorbs more sunlight than arctic ice, increasing the total amount of warming.” (EPA CITE). All in all, most causes of climate change lead back to carbon dioxide. For example, carbon sinks, such as trees and oceans, absorb carbon dioxide. But increased deforestation leads to less absorption of the greenhouse gas. And as oceans get warmer, they increasingly release carbon dioxide into the air, while absorbing the gas at a slower rate.
Climate change is such a wide-reaching phenomenon, that it can affect everyone in the world. Scientists have categorized the inputs of the warming phenomenon into three categories: (1) Erratic climate and weather extremes; (2) Altered ecosystems and habitats; (3) Risks to human health and society. To start, Earth’s water systems will be heavily impacted by climate change. The planet 's glaciers and ice will melt at an increased pace. This will contribute to rising sea levels…
