The History of Earth’s Climate

The Earth has had a long history. In it’s 4.5 billion years of being in existence, it’s looked like everything from a ball of molten lava, to a giant tropical rainforest, to a big snowball. The point is, the climate here is never stable, it’s always changing due to a number of different factors. For instance according to San Diego State University, “…in 1815, the eruption of Mt. Tambora, Indonesia, resulted in an extremely cold spring and summer in 1816, which became known as the year without a summer. The Tambora eruption is believed to be the largest of the last ten thousand years. New England and Europe were hit exceptionally hard. Snowfalls and frost occurred in June, July and August and all but the hardiest grains were destroyed. Destruction of the corn crop forced farmers to slaughter their animals. Soup kitchens were opened to feed the hungry. Sea ice migrated across Atlantic shipping lanes, and alpine glaciers advanced down mountain slopes to exceptionally low elevations.” (5) So while people might be complaining that it’s too hot now, just one eruption like this and we could all be wearing coats and scarves in the Florida summer. Whenever people are quick to blame humans for a rise of temperature in the last hundred years, they should look at the hard facts of Earth’s climate history.

During the Cretaceous Period 250 million years ago, global temperatures averaged around 82°F, a full 23° higher then what it is today. This was before mankind was around, and it was much hotter! Also, looking at the cyclical climate that Earth has, every warm period is immediately followed by a cold spell or ice age. It doesn’t matter how hot the Earth gets, an ice age will always follow, so humans have nothing to be worried about anytime soon.
