Climate Change and Global Warming
What Is Global Warming And Climate Change?
Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “greenhouse” gases such as Carbon Dioxide (CO2).
A warming planet thus leads to a change in climate which can affect weather in various ways, as discussed further below.
What Are The Main Indicators Of Climate Change?
As explained by the US agency, the National Oceanic and Atmospheric Administration (NOAA), there are 7 indicators that would be expected to increase in a warming world (and they are), and 3 indicators would be expected to decrease (and they are):

What Is The Greenhouse Effect?
The term greenhouse is used in conjunction with the phenomenon known as thegreenhouse effect.
