Is it possible that we are wrong about why the planet's temperature is going up? I mean has anyone thought about the fact that our planet weighs a lot more than it used to because of all the people living that have been saved by doctors. Last time I checked our solar system was mapped out by gravity. So isn't possible that because of our increased weight we are being pulled closer to the sun?

Sorry. The temperature might be rising for some other reason, but increased weight of the planet is not one of the possibilities. The reason is that the planet has not increased in weight, no matter how many people are alive or other creatures for that matter. All of the atoms that make up the people have been on the planet before the people were born. The molecules that make you up, come from what you eat, breath, and drink. And all those atoms were part of the air, or part of the ocean or part of the ground. Same with everyone. So the planet is not gaining weight. It would have to pick up material from outer space. And although there is a tiny amount of matter that come in that way, it's really insignificant compared with the amount that's already here.

The temperature per unit mass of the earth does change with time.
The reason is that the amount of insolation given by the Sun decreases with time ,because the Sun as it loses energy radiates less and less.
The Earth is increasing in mass with time as as a result there is a change of orbital velocity dues to greater mass.
As mass increases due to gravitational phenomenon the Velocity of the earth changes,it becomes slower and time becomes longer (Dilates).The rate of the Earth'a atom mass increase is due to absorption of cosmic mass radiation and Sun's mass radiation.
The earth's mass increase(planet's weight as you refer) causes not a decrease of the Earth orbit around the Sun; but rather an increase of the orbit and a change in the earth's
elipticity. Hence, the Earth is continually moving away from the Sun as its mass increases.
Therefore temperature changes on the earth are more complicated that what science give it credit for.
The Precession of the Earth's poles is related to
seasonal changes. Hence the earth has in the past experienced seasonal changes. From warm temperate weather to ice weather (ice age).
At present other factors relate to changes of weather . The Cutting down of forests and incendiations of forests have been the causes of the changes we are observing in the weather.
The most serious problem of weather change is the modern industrial atmospheric polution by particulates which obscures the atmosphere.This cause less insolation resulting in global cooling,which will cause a decrease of precipitation.
PS; The number amount of mass Human have, forms a conservative system of mass. The mass gained from a baby comes from the Dust of the Earth and when a person dies its weight returns to the dust of the earth.

Where did all the people on the planet come from? From the planet. There is no extra mass on this planet caused by increasing population. It is just a reordering of existing matter. When you grew up your extra mass was provided by the food you ate, which came from Earth in the first place. So while there was more of you there were less plants and animals because you'd eaten them.

You should be able to test your idea. If you have everyone jump up in the air at the same time, the earth will move back a little ways from the sun if you're rignt.

The earth is increasing very slowly from all the space rocks falling in . The people regardless of how big all comes from the mass of the earth. From dust to dust. The plants provide our food and they come from the earth and CO2.

Apart from the correct response by the previous respondent, the weight of humans is negligible compared to bacteria, anyway. The Earth is an almost closed system. We are, in essence, eating eat other.

William D has a point.the temperature is rising because of the ozone's hole.that is causing the global warming.So there.

No, it's not possible. Just take our word for it.
