CAUSES  

Burning Fossil Fuels: Burning Fossil fuels are when we use resources that are limited to mankind and we burn them (Ex: Coal and Oil). This results in Carbon Dioxide (CO2) released into the atmosphere. When Carbon Dioxide is released into the atmosphere, it enhances the suns rays and these rays burst through the ozone layer and therefore the temperature of the planet increases by a vast margin, resulting in the planet warming up.

Deforestation: all the trees have stored carbon in them which they after a million years convert into coal, etc. Be that as it may today humans are cutting down the forests and all the green areas in order to make industries and factories. When they do so the stored carbon is converted into carbon dioxide.

Farming: Today more than 14% of earth’s greenhouse gases are coming from cattle and some of their fertilizers. Which in turn contributes to the enhanced greenhouse effect.

Industry: Many industries like cement production and the nuclear industry let out greenhouse gases that add more to the greenhouse effects. overheating the place as the heat is trapped inside because most of these gases do not pass out of the atmosphere unlike in the natural greenhouse effect.

Sunspots: With sunspots come an increase in ultraviolet rays that emit from the outer ring of the sunspots toward Earth. This increa. The idea that sunspots affect Earth's climate is still largely debated, but it is believed that the increase of sunspots on the surface of the sun can reduce the amount of energy and light distributed to Earth. This decrease in energy can result in colder weather and even "mini ice ages" on parts of Earth.se in UV rays affects chemistry of the outer atmosphere and the energy balance of Earth.
