Bio Climate Change week 7

Infrared radiation

The light interacts with Earth and bounces off causing it to radiate back to space as

Radiative Forcing

Greenhouse gases ‘intercept’ & reflect this energy back to earth, heating the Earth

The Greenhouse Effect

Traps heat and warm Earth's surface, making the planet habitable

Natural Greenhouse Effect

trap heat from the sun, warming the planet to a temperature suitable for life

Risks of a warming planet to humans and the natural world

 mess up the ecosystem by spring being earlier than it usually is to animals and to humans it could cause skin cancer and natural disasters occurring more frequently like heatwaves and floods.

Human Enhanced Effect

Less heat escapes into space

• a consistent change over a long period of time—consistently warmer winters
