Greenhouse effect brings Earth to Jurassic

Warming oceans will cause sea levels to rise If the temperature is warmed by the greenhouse effect, the Earth could return to the Jurassic period 150 million years ago. That means, every creature is destroyed .

Recently, at an international scientific conference, held in Nanjing, China, more than 80 scientists around the world warned that the Earth could return to the Jurassic period 150 million years ago.

This is the period when the Earth's temperature and sea level rise and destroy all species.

Archaeological findings show that the stratigraphic stratigraphy of the Jurassic period is very clear, above the red stratum, the red stratum below, and the middle of the mines with large reserves, that said the greenhouse effect had arisen during Jurassic period. The temperature at that time certainly increased very high, so the mud turned red, but in that red stratum there was no trace of biological fossils, showing that every creature was destroyed. clean.

More recent evidence suggests that the concentration of carbon dioxide in the atmosphere of 400 thousand years ago was about 180 to 280ppm (the number of carbon dioxide molecules / 1 million molecules gas, but since the industrial revolution was born, this concentration has been constantly increasing, by 2004 this number had reached 379ppm. This is a condition that resulted in a serious greenhouse effect in Jurassic period.

Scientists predict that if the carbon dioxide concentration is kept increasing, after 100 years or in a shorter time, it is likely that the greenhouse effect has the same level of time. Jurassic period will reappear. At that time, the polar ice of the earth will melt, the land will be narrowed, the temperature will rise and a large number of creatures will be destroyed. Venus is the lesson about the greenhouse effect for the earth.

The surface temperature of Venus is close to 5000C and does not allow the existence of any kind of creature.

Not only is it dry and hot, over 90% of Venus's atmospheric component is carbon dioxide, atmospheric pressure is 90 times higher than Earth. In addition, Venus is covered by a thick layer of cloudy sulfuric acid.

The cause of heat in Venus is because of the greenhouse effect.

With Venus, some scientists predict that there has been a warm environment here, but the appearance of an uncontrollable greenhouse effect has made the entire water surface on Venus evaporate (water evaporation also increases the greenhouse effect), so in the end, Venus is turned into an "oven" as it is today. Although the "greenhouse effect" has become one of the concerns for global temperature, if there is absolutely no greenhouse effect, the earth's temperature will always be below 00C and there will be no life. .

By the end of the 21st century, the earth's temperature may increase from 1.4 to 5.80C due to the greenhouse effect, which also means more threats from natural disasters. People will face the dangers caused by themselves if not controlled promptly.
