Global cooling ended at the end of the 19th century. According to warmists, this is because of the rise of industry which began to emit pollution (carbon dioxide).
The period of global cooling from the fourteenth to the nineteenth century is often referred to as the Little Ice Age. This era was characterized by colder temperatures and adverse climatic conditions, leading to shorter growing seasons and harsh winters in various parts of the world.
The reverse change of global warming is global cooling, which refers to a decrease in average temperatures worldwide. Global freezing is not a recognized scientific term but can be used colloquially to emphasize extreme cold conditions.
The opposite of global warming is global cooling, which refers to a decrease in the Earth's average temperature over an extended period of time.
None. There was a slight cooling around the middle of the 20th Century caused by the amount of pollution particles in the air. These were reflecting the sun's rays. When Clean Air Acts began to take effect around the world the air became cleaner and the cooling disappeared.
During the mid-20th century, scientists observed that global temperatures were decreasing, which led to concerns about global cooling. This cooling trend was likely influenced by natural climate variability, such as increased aerosol emissions from industrial activities and volcanic eruptions, which can block sunlight and have a cooling effect on the climate. However, as our understanding of climate science improved and more comprehensive data became available, it became clear that the long-term trend is global warming due to human activities.
Not any more. There was a time in the mid-20th century when burning fossil fuel, particularly coal, put so much dust and particulate matter into the atmosphere that it reflected some of the heat from the sun, reducing the effects of global warming. Clean Air acts later made the atmosphere clean again and global cooling disappeared.
No, definitely not.
It cools it somewhat. Global cooling occurs after a volcanic eruption when clouds of dust remain in the sky for several days reflecting the sun's rays. This results in a cooling of the atmosphere.

If global cooling means the gradual cooling into an Ice Age, then that has happened in the past and it has taken thousands of years to happen. The present global warming has all happened far faster, in less than 200 years, and is threatening all life on the planet if we can't stop it. Global warming is by far the more dangerous situation.
Clean air does not prevent global warming. In fact, dirty polluted air in the mid-20th century actually slowed global warming a little as it reflected solar radiation away from the earth. Various Clean Air Acts around the world stopped this global cooling, and the warming continued.
There was a time in the 1970s when scientists though the earth might be approaching a global cooling period. This was quickly proved incorrect. But a possible result of global cooling would be more ice caps, larger glaciers, colder winters, cooler summers etc.
