Climate Change

Climate change represents a change in these long-term weather patterns. They can become warmer or colder,Annual amounts of rainfall or snowfall can increase or decrease.

The terms “climate change” and “global warming” are often used interchangeably.

Generally WWF use the more scientifically accurate term “climate change”, but we often use “global warming” as it remains popular in public discourse.
This definition from the NASA website is perhaps the best way to approach the two labels.

“Global warming refers to surface temperature increases, while climate change includes global warming and everything else that increasing greenhouse gas amounts will affect.”

First, the Sun emits energy that is transmitted to Earth. Because the Sun is very hot, the energy is emitted in high-energy short wavelengths that penetrate the Earth’s atmosphere.

About 30% of the Sun’s energy is reflected directly back into space by the atmosphere, clouds, and surface of the Earth. The rest of the Sun’s energy is absorbed into the Earth’s system.

The Earth emits energy into the atmosphere. Because the Earth is cooler than the Sun, the energy is emitted in the form of infrared radiation, at wavelengths longer than the incoming solar energy.
