It seems that the volcanoes could be at fault to this greenhouse effect, about 500 million tons of volcanic CO2 is put out every year but it’s nowhere near the amount that we produce due to using oil and other fossil fuels. A small greenhouse effect is a good thing, though a big one won’t have a good outcome. With no CO2 on our planet, Earth would be a big snowball. The incoming light from the sun hits the surface the Earth absorbs the heat making the infrared light. Neil shows us the Earth in the Infrared we see its own body heat. The 20th century was the beginning of the carbon dioxide increase in our oxygen CO2 is building up in the atmosphere warming up the planet. The Earth keeps a detailed diary in the snow, the ice layers have ancient air trapped inside of them. The Earth has been breathing like this for years we had no idea until a man named Charles found out about it. Plants drop their leaves in fall exhaling the carbon dioxide the southern hemisphere does the same but at different times. When spring comes to the north the plants inhale carbon dioxide making them turn green. The Earth in stunning contrast is alive, it breaths, but very slowly a single breath takes a whole year. Venus had no way of capturing CO2, which lead to its demise. With no CO2 at all the Earth would be frozen, though if we had too much Earth would get uncomfortably hot not like Venus though. Later the restless Earth pushed up the sea floor and carved the massive cliffs Neil is standing in front of. A creature a thousand times smaller than a pin head are shown, volcanos provide carbon dioxide into the air.
Most of the carbon on Earth has been stored for eons. The Soviet Union landed a robot on Venus, they were able to take pictures of Venus due to keeping the robot cool it only lasted about two hours and the robot finally over heated. Venus’s oceans are long gone, the surface is hotter than a broiling oven it turns out that the reason it’s so hot is because the small rays of sun light have a hard time leaving the planet. The planet Venus which once may have seemed like Heaven turned into a kind of hell, when things started to unravel there was no way back. We then see what Venus looked like before everything went horrible wrong, from blue waters of beauty to a planet starting to be destroyed. RECAP: Once there was a world not so very different from our own, there were occasionally catastrophes for the first billions of years there was none. Tune in at 9 Pm EST on FOX and we’ll be recapping it right here for you but in the meantime, hit up the comments and let us know your thoughts on the show so far. Tonight is going to be another interesting episode of Cosmos for sure and you’re not going to want to miss a minute. However, with knowledge, technology and science within our grasp imagine a hopeful future where we dedicate our efforts to taking care of our home, Planet Earth. Later, explore the detrimental effects of climate change and trace the magnitude of our impact on the Earth’s atmosphere. On tonight’s episode the Ship of the Imagination travels to our near neighbor Venus, where we begin our journey to discover the long history of global warming and the greenhouse effect.

Did you watch last week’s episode? If you missed it we have a full and detailed recap, right here for you.
Then, visited the Cosmic Calendar of the Future and contemplated what lies ahead with a hopeful vision. On last week’s episode the Ship of the Imagination traveled across the cosmos to discover the possibility of beings that lived forever and explained why other civilizations perish. Also: an examination of climate change on Earth and what it means for the future. Tonight on FOX Carl Sagan’s stunning and iconic exploration of the universe as revealed by science, COSMOS: A SPACETIME ODYSSEY returns to FOX with a new episode called, “The World Set Free.” A look at Venus and what may have happened to it as a result of the greenhouse effect.
