n. Global climate change in the form of declining average temperatures.
Wikipedia
Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere culminating in a period of extensive glaciation. This hypothesis had little support in the scientific community, but gained temporary popular attention due to a combination of a slight downward trend of temperatures from the 1940s to the early 1970s and press reports that did not accurately reflect the full scope of the scientific climate literature, which showed a larger and faster-growing body of literature projecting future warming due to greenhouse gas emissions. The current scientific opinion on climate change is that the Earth has not durably cooled, but underwent global warming throughout the 20th century.
Global cooling was a 1970s conjecture about global climate change.
Global cooling may also refer to:
- In general, one of the means by which Earth can undergo climate change
- Climate change denial, including contrarian views about global warming in the 20th and 21st centuries
- Cooling periods on the multimillion-year scale in the geologic temperature record
- Geophysical global cooling, a conjecture about the formation of natural features that was made obsolete by the theory of plate tectonics
- Little Ice Age, a period from the 16th to 19th centuries characterized by cooling and coincident with below average sunspots frequency
Usage examples of "global cooling".
Depletion of the ozone layer, global warming from an increased greenhouse effect, and global cooling from nuclear war are all ways in which present technology can significantly alter the environment of our world—.
Depletion of the ozone layer, global warming from an increased greenhouse effect, and global cooling from nuclear war are all ways in which present technology can significantly alter the environment of our world-and in each case as an inadvertent consequence of doing something else.
At least two dozen potential culprits have been identified as causes or prime contributors: global warming, global cooling, changing sea levels, oxygen depletion of the seas (a condition known as anoxia), epidemics, giant leaks of methane gas from the seafloor, meteor and comet impacts, runaway hurricanes of a type known as hypercanes, huge volcanic upwellings, catastrophic solar flares.
The reptile predators of the Mesozoic were far from intelligent, and there was nothing to indicate that, if they had not been exterminated by a catastrophe between the Cretaceous and Jurassic (a giant meteorite disrupting the food chain through the global cooling of the climate), the dominant reptiles of the time would have acquired humanlike brains.
What if Richard could reverse some of that damage, buffer both the current global cooling and the looming catastrophic warming trend, and stabilize the climate?
Yatima recalled the C-Z analysis stating that these waves could do real damage under certain conditions, though any effects would be highly localized, and insignificant compared to the problems of UV and global cooling.
We might well have some global cooling for a period of years, much as if a couple of very big volcanoes erupted at the same time, and, depending on the upper-level winds here, an even more dramatic effect on the South American and possibly African continents for some time.
