Climate change is an issue that worries many scientists.
The action and effect of changing is known as change (from the Latin cambium ). In many cases, it is used as a synonym for replacement , exchange or substitution . The verb change, for its part, refers to leaving one thing or situation to take up another .
When someone receives a piece of clothing as a gift , it is very common for them to want to exchange it for another, either for a matter of taste or because the size is not appropriate for their body. In this sense, when buying clothes, the store usually asks if exchanges and returns are accepted, given that in some cases the person receiving the product does not find anything they like and decides to keep the money.
Sometimes the need or desire is felt to replace an appliance or a car, among other belongings, with one that is more modern or that has certain very particular characteristics, and in this context the verb change is also used. An expression that usually goes hand in hand with this action is "it's time to"; For example, when an old refrigerator starts to break down and you notice that it won't work for much longer, you can say that "it's time to change it."
Stages of change
On the level of feelings, human beings usually go through stages of change or transition , especially when we reach a point in our lives in which we feel that we cannot continue moving forward .
These crises, very necessary for the intellectual development of all people, are generally related to vocation and love; enduring for years an unwanted job with abusive conditions, which generates a feeling of oppression and imprisonment can lead an individual to rethink their decisions, just as a relationship in which there is no love and understanding for the other can bring about a change.
Climate modification
When the climate of a region or the planet is modified, taking into account the known history, we speak of climate change . This phenomenon can take place due to issues of nature, or due to the actions of man; It can be reflected in alterations in atmospheric pressure, temperature, rainfall, or any meteorological parameter, and the transition time between both states is absolutely variable.
It is very common for this concept to be used when talking about global warming, which is imprecise.
The relative value of the currencies of different countries is known as exchange rate.
Money and change
On the other hand, the notion of change is associated with money . The exchange rate is the relative value of the currencies of different countries : «The exchange rate rose to 3.78 pesos» , «The exchange between the euro and the dollar no longer favors us» , «I advise you to go to an exchange house more than a bank .
This term is also used to refer to fractional money of higher value bills ; That is, the change of a fifty peso bill is made up of five ten peso bills, ten five peso bills, three ten bills and one twenty, etc. In this sense, merchants must always have change to be able to deliver the change (also called "the return") to their buyers. If a person purchases a product that costs forty pesos and pays with a fifty peso bill, the merchant must have the necessary change to return the remaining ten pesos.
The concept associated with speed
Finally, the notion of change refers to the variation of speeds in a car or, figuratively, to the pace of life.
Thus, you can say that a car has an automatic gearbox and you can also ask a person to "shift down", that is, to calm down, referring to their state of nervousness or stress.
