cause the last ice age ended 18 thousand years ago millions of years ago oxygen increased in the earths atmosphere due to a surplus of plants and a few decades ago carbon reached its peak cause of human activity and the use of fosil fuels

or i may be wrong and everything i just said is wrong and my arguement is null.

I believe you What but if its wrong i will be sad

Billions: Oxygen build up

Ocean acidification: make shells, carbonic acid, prone to illness
Ocean warming: melting glaciers, expansion of volume, absorbing carbon dioxide

Decreased ice causes less energy to be reflected

Indicates weather that year was warm, wet

a and b c here for you informant A permutation is an arrangement of objects in a definite order. The members or elements of sets are arranged here in a sequence or linear order. For example, the permutation of set A={1,6} is 2, such as {1,6}, {6,1}. As you can see, there are no other ways to arrange the elements of set A.

In permutation, the elements should be arranged in a particular order whereas in combination the order of elements does not matter. Also, read: Permutation And Combination

When we look at the schedules of trains, buses and the flights we really wonder how they are scheduled according to the public’s convenience. Of course, the permutation is very much helpful to prepare the schedules on departure and arrival of these. Also, when we come across licence plates of vehicles which consists of few alphabets and digits. We can easily prepare these codes using permutations.
