Global warming
Global warming is a term used for the observed century-scale
rise in the average temperature of the Earth's climate system and its
related effects.
Scientists are more
than 95% certain that nearly all of global warming is caused by increasing
concentrations of greenhouse gases (GHGs) and other human
caused emissions
Our atmosphere is getting hotter, more turbulent, and more unpredictable because of the “boiling and churning” effect caused by the heat-trapping greenhouse gases within the upper layers of our atmosphere. With each increase of carbon, methane, or other greenhouse gas levels in the atmosphere, our local weather and global climate is further agitated, heated, and “boiled.”
Global warming is gauged by the increase in the average global temperature of the Earth. Along with our currently increasing average global temperature, some parts of the Earth may actually get colder while other parts get warmer hence the idea of average global temperature. Greenhouse gas-caused atmospheric heating and agitation also increase the unpredictability of the weather and climate, and dramatically increase the severity, scale, and frequency of storms, droughts, wildfires, and extreme temperatures
