How does research of Mars and Venus contribute to our understanding of global warming?

Question

Global warming: Man made, or nature? I'm having a little issue in figuring out the facts about Global Warming. Many scientists seem to be divided on the issue, some say its man made, others say its just a natural cycle, but most agree its a occurring thing. What I've been researching has led me to the topic of Venus, our closet, and astronomers say our "Twin sister". They say that Venus underwent a violent green house effect that caused its once oceans to evaporate which destroyed life. The atmosphere of Venus is made up of mostly CO2 and nitrogen, and is 92 times denser than Earth. Even though its twice as far away from the sun, its still considered hotter than Mercury, 462 degrees Celsius (735 F). I can't really find much on what caused this sudden change. What bothers me even more is why NASA is funded mostly for its research towards mars and being the first to have a man land on it. Why research something like mars, when we have a planet that could be our very future selves?

though there are divided thoughts upon this but many feel that inner planets of our solar system are interlinked .

I believe that there are both natural and man-made causes for global warming. Consider this: thousands of other extant species were also producing carbon dioxide and methane prior to the arrival of humans. Global warming would eventually result from the production of gases like carbon dioxide and others, even if humans were intelligent or lived like any other animal. However, because of our careless actions, which have numerous negative effects, humans have created these gases at an exponential rate; every year, data shows a new record for the hottest year; we have destroyed ecological balance and chopped down trees, so there is no stability or natural countermeasure to lessen global warming; this activity of global warming was very slow, like matrix, and would not have affected the earth's balance. Venus, on the other hand, is extremely hot due to its atmosphere of CO2 and rains of H2SO4, which trap heat from the sun and make it warm. This makes it difficult to conduct experiments as it would break up or burn down the module. It is possible that Venus is not our future but rather the aftermath of our planet. Mercury, on the other hand, has no atmosphere. Mars was specifically chosen because it is hard and sturdy where we can conduct ground experiments. it has also promised us large reservoirs and bacteria existence. Finally, while Venus's unfavorable conditions continue to disturb us, any evidence of life on or emerging from it is not very satisfying. Planets like these aid in our understanding of our own planet, its possible formation, and possible events.

undefined Studying Mars and Venus provides insights into the greenhouse effect and helps compare and contrast planetary atmospheres, aiding our understanding of Earth's climate and global warming.
