The greenhouse effect is a phenomenon that determines the flow of energy from the Sun to Earth, with planets like Earth, Venus, and Mars having an atmosphere containing water and carbon dioxide. These planets have a thick atmosphere that traps heat, leading to extreme atmospheric pressure. A runaway greenhouse effect occurs when greenhouse gases accumulate in the atmosphere through a positive feedback cycle, blocking radiated heat from escaping into space.
Mars, on the other hand, does not exhibit any greenhouse effect. Its surface temperature is about 460 degrees Celsius, hot enough to melt lead. The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas. Venus exhibits an extreme greenhouse effect, making it the planet with the hottest surface temperatu. The initial velocity an object needs to break free from the surface of a planet is about 460 degrees Celsius.
Earth is expected to experience a runaway greenhouse effect “in about 2 billion years as solar luminosity increases”. Venus and Mars are extreme examples of how greenhouse gases can impact a planet. The impact of the greenhouse effect on Earth is becoming increasingly stronger as we add greenhouse gases to the atmosphere, which is warming the climate of our planet.
In conclusion, the greenhouse effect affects all planets differently, with Earth, Venus, and Mars being the most extreme examples. As the greenhouse effect becomes more intense, it is crucial to understand how it impacts a planet’s conditions and how it can be mitigated.

Does Uranus have a greenhouse effect?
The greenhouse effect is a warming phenomenon where a planet’s atmosphere traps heat from the Sun, causing it to enter but not leave. This phenomenon is observed on planets like Venus, where solar radiation enters the atmosphere and is reflected back into the atmosphere. The re-radiated heat is trapped by carbon dioxide, resulting in a scorching surface temperature of 900 degrees Fahrenheit (482 degrees Celsius). The greenhouse effect is also present on Earth and the upper atmospheres of giant planets like Jupiter, Saturn, Uranus, and Neptune.
What planets has an extreme greenhouse effect?
Venus, similar to Earth in size and mass, has a surface temperature of 460 degrees Celsius, hot enough to melt lead. Its atmosphere is primarily composed of carbon dioxide, a greenhouse gas. Man-made emissions have caused a 30 percent increase in carbon dioxide concentrations since pre-industrial times. Project Scientist Hakan Svedhem, Project Scientist for ESA’s mission Venus Express, aims to understand why there is so much carbon dioxide in Venus’ atmosphere and why it evolved differently from Earth.
Venus will help understand extreme greenhouse effects, but it is not a good example of what Earth would be like due to human activities. Life on Earth would likely disappear before reaching even half of the concentrations on Venus.
Which of the planets on the figure has the strongest greenhouse effect?
Venus has the strongest greenhouse effect on Earth due to its carbon dioxide-dominated atmosphere, which has a large thermal opacity 100 times greater than Earth’s. This results in a 15 times greater greenhouse effect than on Earth, causing a surface temperature of nearly 460°C (860°F), hot enough to melt lead and vaporize mercury. This extreme greenhouse effect renders Venus inhospitable to life.
Mars’ thin atmosphere can only withstand a few degrees of greenhouse warming, while Mercury’s surface temperature is determined solely by local thermal equilibrium with absorbed sunlight. Climate scientists are most concerned about the rising atmospheric levels of carbon dioxide, a much less abundant gas, as it is the most affected by the greenhouse effect. The rising atmospheric levels of carbon dioxide are a significant concern for climate scientists as it could contribute to the global warming of the planet.
Which planet has a very hot greenhouse effect?
The thick atmosphere of Venus traps heat, creating a runaway greenhouse effect that makes it the hottest planet in our solar system. The surface temperatures are sufficiently elevated to melt lead, resulting in a temperature on Venus that is approximately 700°F (390°C) higher than it would be in the absence of the greenhouse effect.
Which planet has a super greenhouse effect?
Scientists believe a runaway greenhouse effect (SGE) on Venus may have occurred due to high levels of carbon dioxide in the Venusian atmosphere, which trapped enough heat to trigger a global SGE that boiled away the oceans. Today, Venus’ surface is hot enough to melt lead. Runaway greenhouse scenarios on Earth are highly speculative, with CO2 levels of a couple thousand parts per million or a massive release of methane being highly unlikely. To characterize SGE regions in a warming world, Kahn, Richardson, and Stephens compared results from a suite of climate models.
They reported that adding more CO2 to the air would make Earth hotter and expand SGE regions, trapping more heat. Scientists are interested in understanding how the extra heat trapped within SGE regions would be transported away from these regions in a warming world.

On which planets is the greenhouse effect present?
Earth, Mars, and Venus have similar atmospheres, interiors, surfaces, and greenhouse gases, but their temperatures vary significantly due to different levels of greenhouse gases. Carbon dioxide dominates the greenhouse gases in these planets’ atmospheres, but the warming on these planets varies significantly. The greenhouse effect on Earth, Mars, Venus, and Titan is influenced by the presence of carbon dioxide, which is a greenhouse gas.
The planets’ temperatures are affected by the greenhouse effect, which is a result of the interaction between the atmosphere, interiors, surfaces, and greenhouse gases. The greenhouse effect on Earth’s temperature without greenhouse gases is also influenced by the presence of carbon dioxide.
Which planet has the greatest greenhouse effect?
Venus, similar to Earth in size and mass, has a surface temperature of 460 degrees Celsius, hot enough to melt lead. Its atmosphere is primarily composed of carbon dioxide, a greenhouse gas. Man-made emissions have caused a 30 percent increase in carbon dioxide concentrations since pre-industrial times.

Do Mars and Venus have a greenhouse effect?
The greenhouse effect on Mars is less pronounced than on Venus due to the thinner Martian atmosphere. It is also important to note that not all surface thermal energy is trapped in the atmosphere.
What is the extreme greenhouse effect?
A runaway greenhouse effect occurs when a planet’s atmosphere contains enough greenhouse gas to block thermal radiation, preventing cooling and preventing liquid water on its surface. This version of the greenhouse effect is defined by a limit on a planet’s outgoing longwave radiation, which is asymptotically reached due to higher surface temperatures evaporating water into the atmosphere and increasing its optical depth. This positive feedback means the planet cannot cool down through longwave radiation and continues to heat up until it can radiate outside of the absorption bands of water vapor.
The runaway greenhouse effect is often formulated with water vapor as the condensable species, which reaches the stratosphere and escapes into space via hydrodynamic escape, resulting in a desiccated planet. Research in 2012 found that it is unlikely to trigger a full runaway greenhouse on Earth by adding greenhouse gases to the atmosphere. However, human actions could cause a transition to a warmer climate state.

If you don’t know, when it comes to archeology, the deeper you go, the further into the past stuff you will find, go a little bit deep, you will find prehistoric human tools, a little bit more deeper, you might find dinosaur bones, I think the same might happen in Mars, so maybe if you dig a little bit deep in Mars, you might find something in there, though I don’t know what might it be.
24:00 far fetched? not at all. I think Mars and Venus were both proto-Earths. I’ve thought this since before 2016. Mars fell fate to nuclear warfare, Venus fell fate to chemical warfare, and soon… well, no one wants to talk about soon… but the Earth still has a few chapters to write. If we succeed in re-colonizing either of those two planets, it will be like opening a new metaphysical book on them. 15:58 Maybe fit the whole idea in one sentence instead of two similar sentences? 18:30 I see two wings and a rectangle… who got a humanoid figure out of this??? 8:55 I know this exact story. A lot of it was proven false, but… well I’d describe it as space black-ops. They named the alien (that ate the original crew) The Mona Lisa. They explored a sci-fi ship with life-like technology. This was all part of an elaborate coverup of what really happend, which might be far more spooky!
That picture of the moon surface looks almost exactly like Morty’s “smudge” on the lens of his telescope. It’s the episode from “Rick and Morty” where Morty thinks his guidance counsellor is some sort of alien because he has this smudge on his telescope lens that made the counsellor seem like he was on the surface of the moon. Turns out, after the suicide of the counsellor that it was just a smudge after all.
I think the scientists believe it, but they all have one question. Where can extraterrestrial life come from? Planets and galaxies are just too far away. I think that it’s very possible that there’s life inside earth. Not a “hollow earth’, but an earth that has massive tunnel systems. We already know about the lakes and oceans that are in the mantle. Alien life in our oceans, and alien life in and on the moon. What is Jupiter really like? I know that two remote viewers saw life on Jupiter. Through that dense atmosphere could there be life? What about the monoliths that have been found on the different moons and planets within our solar system? There’s even a monolith on Mercury. Several astronauts questioned the thought about life in outer space. Meaning they really think (know) that life exist is the vastness of space itself. Things like angels, octopus looking creatures, and space snakes have been seen in space. Those so-called space snakes have actually been seen, and articleed in our upper atmosphere.
I believe in extraterrestrial life our universe is most mysterious and unique, there are some planets very far million or billion miles away from earth and there are more living things that planets of Aliens ..some of there spaceships are most fast speed and super hytect than in our spaceships on earth..they monitor us here on earth some aliens study and interested if what is really happening in our planet.. .the computer inside the spaceships of alien is so big around all over inside they can zoom most hytect they saw all the movements here on earth..
Why is it, that when people show things on the moon, Mars, or wherever, they show the public these pictures of something from far away, but never zoom in on the object they are showing. Cause there is people seeing it, but can not see what it is that you or others are showing off, that good from that far away. Why is it that N. A. N. S., and others never zoom in on the object they are trying to show the general public. ???
