What makes the climate change?

This effect is a natural phenomenon, which helps maintain a stable temperature and climate on Earth

Increasing greenhouse gases trap more heat “Greenhouse effect” Increasing greenhouse gases trap more heat [Image 1] Earth’s surface absorbs heat from the sun and then re-radiates it back into the atmosphere and to space. [click, Image 2] Much of this heat is absorbed by greenhouse gases, which then send the heat back to the surface, to other greenhouse gas molecules, or out to space. Though only 1% of atmospheric gases are greenhouse gases, they are extremely powerful heat trappers. By burning fossil fuels faster and faster, humans are effectively piling on more blankets, heating the planet so much and so quickly that it’s hard for Mother Nature and human societies to adapt. 7
