Pollution was blocking sunlight.
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.
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.
Approximately 97 of climate scientists believe in global warming.
Approximately 97 of scientists believe in man-made global warming.
According to multiple studies, less than 3 of scientists do not believe in global warming.

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.

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.
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.
Some suggest that in the absence of other factors, there should be a slight cooling at the present time. Whether or not this is true, it is being swamped by a quite rapid warming effect. The consensus of climate scientists is that global warming is happening and is caused substantially by human activities. the last ten years were the warmest since instrumental records began in 1850.
Approximately 97 of climate scientists believe in global warming.
Global warming is when the global average annual temperature is generally trending upward. Global cooling is when it is trending downward.A:Global warming is happening now. Global warming is not beyond the control of mankind. It is being caused by our dependence on fossil fuels (coal, oil and natural gas) which we are burning to produce electricity.
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.
As with all issues, not ALL scientists believe in the link between human activity and global warming. However, the majority of scientists feel that the evidence for global warming is adequate to prove its existence. The majority of scientists who reaffirm the theory of global warming believe there is a link between climate and human activity. According to the Union of Concerned Scientists, "The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) states: it is a greater than a 90 percent certainty that emissions of heat-trapping gases from human activities have caused "most of the observed increase in globally averaged temperatures since the mid-20th century." "
Approximately 97 of scientists believe in man-made global warming.
