The Fahrenheit scale was the primary temperature standard for climatic, industrial and medical purposes in most English-speaking countries until the 1960s. In the late 1960s and 1970s, the Celsius (formerly Centigrade) scale was adopted by most of these countries as part of the standardizing process called metrication (or metrification). Only in the United States and a few other countries (such as Belize) does the Fahrenheit system continue to be used, and only for non-scientific use. Most other countries have adopted Celsius as the primary scale in all use.
The 3 main fossil fuels that affect the atmosphere are:coalnatural gasoilWhen burned, these release carbon dioxide into the air.However, did you know that ANY burning of ANY items also release CO2?Until about the 1970s, every family in the US had a "burn barrel" in the backyard where they burned household trash. This became illegal in most communities between 1970-1980 because people complained about the smoke smell.Around the same time, 1970-1980, communities in the US were forbidden to burn autumn leaves they collected from their lawns / yards. Families did this burning every September. Now, leaves must be bagged for garbage, or mulched.However, still today in many countries, people do "slash and burn" farming. They cut unwanted vegetation ("slash"), let the piles dry, and set the piles on fire ("burn"). Across some countries, the land shows blackened "burn scars". In some areas, the air pollution becomes so bad that it affects neighboring countries.In many countries, including the US, traffic clogs roads. The burning of gasoline in the cars' gas tanks causes emissions that include CO2.
Pollution was blocking sunlight.

As long ago as the nineteenth century, scientists discovered that changes in the level of atmospheric carbon dioxide gases can result in corresponding changes in global average temperatures. However, they did not yet have sufficient evidence that carbon dioxide levels were beginning to increase or that global average temperatures were beginning to increase correspondingly. Since the 1970s, climate scientists have linked the rise of more than 35 per cent in atmospheric concentrations of carbon dioxide to the concurrent rapid rise in global average temperatures. They have also proven that the increase in carbon dioxide levels are caused by human activities. So, joining the dots, global warming is caused by human activities.
In the 1970s, the percentage of women in the workforce in the United States was around 43%. This era marked a significant increase in women participating in the labor force compared to previous decades.

In the 1970s, fewer women went to university compared to today. The women's movement in the 1970s helped pave the way for more women to access higher education, resulting in a significant increase in the number of women attending university today.
The 1970s are often associated with a significant increase in drug use and abuse, particularly with the popularity of recreational drugs like marijuana, cocaine, and LSD. The counterculture movement of the 1960s extended into the 1970s, contributing to a widespread use of drugs during that decade.
There was a worldwide energy crisis in the 1970s. Watergate was a significant political scandal and the Iran Hostage Crisis were significant events in the United States. The Vietnam War persisted through the first 5 years of 1970.
The 1970s and 1980s saw an increase in horror movies. More relevantly they also saw an increase in the influence of Christian fundamentalism, the average age of Americans, support for consumer and environmental movements and the number of women holding political office.
