Global Warming Versus Climate Change…
Global Climate Change: Identifiable change in the climate of Earth as a whole that lasts for an extended period of time If due to natural processes, it is usually referred
to as global climate variability Usually refers to changes forced by human
activities that change the atmosphere
Global Warming: Rising ongoing change in Earth’s global temperature near the surface
Caused mostly by increase in greenhouse gases Represents only one aspect of climate change
