every year we get closer to the sun, is that true?
is that the cause of global warming?

No and no. We're not getting closer to the sun. the sun is actually dying because it's running out of hydrogen to burn. It is getting bigger and will become what is known as a "red giant". This will happen gradually and in about 4 billion years the sun will engulf most of the inner solid planets. Global warming is caused by greenhouse gases like carbon dioxide and methane. A great example of this is the planet Venus. It's atmosphere (which is almost entirely carbon dioxide) is so think that when light from the sun enters it heats the surface and is unable to escape making Venus's surface temperature hotter than that of Mercury (about 750 degrees)

That is not exactly the cause.
If we assume that the steady state theory is true, we are not getting closer to the sun. The cause of global warming is owing to the increase of particulate matter which is not allowing the incident heat to escape to the external world.
To understand this, assume a hollow glass hemisphere. Keep this hemisphere in the sun. The incident heat will make everything hot inside as the heat is not able to escape back to the atmosphere.

Nah the earth's orbit around the sun is elliptical (Oval shaped), which means that during the summer months the earth is closer to the sun whereas during the winter we're further from the sun. Global warming does and will not affect earth's heliocentric orbit around the sun.

An astronomer should anwser this question. What it´s true is that the sun is much bigger than planets. If Newton were alive, he´d probably answer that it´s true. But he´d add that this movement towards the sun is to small for the earth to be affected.

No we don't get closer to the sun but the sun is putting out more power now which is a normal cycle for it.

Um... Actually, these people have it backwards. Scorpio starts the 23rd and Libra ends. I believe they might think that Scorpio comes before Libra but in fact Libra comes before Scorpio. Basically, Libra is from September 23rd to October 22nd. Scorpio is from October 23rd to November 21st. So you're a Scorpio, just like me. Although since you're so close to Libra, you might display some of the Libra characteristics. If you want me to tell you some of the personality traits for both signs, you can message me 'n I'll be happy to help. Luck.

Global warming is caused by 'carbon dioxide' in the air ... which is because there aren't enough 'green, growing things' to take it out of our atmosphere, and is now a 'pollutant' ...
As for our planet 'getting closer' to the sun ... we may be doing that ... but since our 'orbit' is ELLIPTICAL (oval) and is 'regular' and has been for millions of years, I don't think that you need to 'worry' about our planet 'falling into the sun' any time soon ... maybe in another 100 MILLION YEARS or so, but not in our 'lifetimes' ...

Nope, its not true. The earth is on an eccentric orbit so the distance varies by 3 million miles but this is insignificant.

who told you that
as if that were true after all these years
we would be having a lot worse temperature
and weather changes than we have now.

to tell you the truth that sounds about right. scary isn't it?
