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

$\large{\underline{\boxed{\sf ANSWER}}}$

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?

Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46% of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
