Global Warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate.
When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.
Its when the earth heats up and happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earths atmosphere, which increases the temperature thus hurting many people, animals, and plants.
Global warming is the trapping of heat in the earth's atmosphere by the greenhouse gases. The heat causes the earth's temperatures to warm up. The earth cycles through periods of warm-ups and cool-downs.
