Answer 1

because of excess of carbon dioxide

Answer 2

To understand this...You must have knowledge of few terms...

Greeh house Effect
CO2 layer around tge Earth
Black Body Radiation..
Specific Heat Capacity...

Once you Know all You can easily understand Why global warming is a serous concern to envitoment...

Green House effect is nothing just traping of heat inside a Glass Chamber or any other way to trap heat...

We create this effect for growing vegetables or plants in polar regions..or the cold regions where sun rarely appears..This is good for plant and vegetable or agricuture..

We also create this effect( Green House effect) By making a layer of CO2 around the Earth...This is no good thing for us....Because during day time Earth absorb heat from the Sun...and it has to radiate out the same amount of heat During night...but Due to layer of Co2 arounf the Earth..some amount of heat gets trapped as a result night become Hotter....This is ehat we call Global Warming...Which also result melting Glacier..ice berg etc...So Gloval warming is really a concern to enviroment...

We human create Co2 layer by producing Co2 by burning Feuls and using other things which produces Co2 like Air confitioners...

If this happen all the time...the time come we get hotter night like a day....

It is suggest to grow trees a plants to save enviroment because trees and plant like Co2 or absorb Co2...So next time whe you go to the park feel the cooling around you...it is just due to Greenary or tree around you...

Hope you understand....

I dint explain the terms Specific heat and black body radiation cz of lenthy content...hope this is sufficient material to help you to understand your question....
