Detailed explanation-1: -For a really strong greenhouse effect, we should look at Venus. Venus is similar to Earth in terms of size and mass, but its surface temperature is about 460 degrees Celsius. This is hot enough to melt lead! The Venusian atmosphere is mainly made up of carbon dioxide, a greenhouse gas.

Detailed explanation-2: -Now Venus is the poster child for the “runaway greenhouse effect, ” a testament to the way a planet can change when the cycles that balance its climate are broken. The temperature at its surface is more than 850 degrees Fahrenheit–as hot as a self-cleaning oven.

Detailed explanation-3: -A few billion years ago, high levels of carbon dioxide in the Venusian atmosphere may have trapped enough heat to trigger a global SGE that boiled away the oceans. This is known as a runaway greenhouse effect. Today, the surface of Venus is hot enough to melt lead.

Detailed explanation-4: -Venus has an atmosphere that is 100x denser than Earth’s atmosphere, and 96% of the atmosphere is carbon dioxide. This creates an enormous greenhouse effect that increases the temperature of Venus approximately 462°C-hot enough to melt lead!

Detailed explanation-5: -’ However, scientists believe Venus did experience a global runaway greenhouse effect about 3 billion to 4 billion years ago.
