Eventually our planet is supposed to get warmer.
The process of the warming of our planet is closely related with the cooling of the Sun.
To be fair, I will first post the article made by Michael Harris, Stellar Evolution and its Effects on Earth.
The Sun's Evolution and the Fate of Life on Earth
To better understand how Earth will be affected by the evolution of the sun it is important to first describe the relationship between the sun, Earth, and life. For this Unit I will briefly describe, or outline, this relationship. Ideally, the subject of Life's relationship with the natural resources on Earth and those relationships with Earth's natural cycles and process would be covered in earlier units. Here we really want to focus on how the Sun affects Earth's natural resources such as water, gases, and soils. Life on Earth owes its existence to liquid water and the proper amounts of certain gases such as carbon dioxide, nitrogen, and oxygen to name a few.
In the past, the Earth had much more carbon dioxide. This is important because carbon dioxide allows solar radiation to pass through it but does not allow radiant heat from the Earth's surface to pass through. Instead it absorbs this heat and reradiated most of it back to the Earth surface. This process has come to be known as the greenhouse effect. This is an important process for life, for without carbon dioxide (and a few other greenhouse gases like methane and water vapor) the temperature of Earth's atmosphere at sea level would be 15 degrees Celsius (60 degrees Fahrenheit) colder.21 That is not to say that life is better off with increasing levels of carbon dioxide. If there is too much carbon dioxide then the Earth's temperature will rise too high and life will be threatened. It should be noted though that the Earth started with more carbon dioxide in its atmosphere than it currently has now. However, the sun's energy output was about 30 percent less and therefore in balance enough to create an environment that was not too cold or too hot for life to take hold. Overtime as the sun's energy output has increased the amount of carbon dioxide in the atmosphere has decreased well. That is, except for the past 50 to 80 years as the industrial revolution took hold. Increased use of fossil fuels and the cutting of forest have caused the Earth's carbon dioxide levels to increase. With the increase in carbon dioxide and other greenhouse gases, it is uncertain what will happen as the sun produces more energy and bathes Earth in ever increasing amounts of radiation. What is certain though is that no matter what our atmosphere is made of, eventually, the sun's will evolve through stages of life and eventually the energy it produces will be too great and will disrupt the delicate relationship between the sun's energy, Earth's natural resources and process, and all living organisms.
With a mass of 1.989 X 1030 kg, our sun is classified as a low mass star.13 And like all stars it began as a huge giant cloud of dust and gas. Gravity pulled these materials closer and closer together until the intense heat at the center cause the hydrogen to fuse into helium thus forming a protostar. Like all other stars on the main sequence, our sun has continuously increased the amount of heat energy being given off. That is to say that in the past our sun did not bath Earth in as much solar energy as it does today. In fact, it currently gives off 30 percent more heat energy than it did at its birth.20
Currently the sun is a main sequence star. It has been burning it hydrogen core for about 5 billion years and is expected to continue as a main sequence star and fully burn up the hydrogen in its core in about another 5 billion years.14 Relatively soon after all the hydrogen in the core is burned the sun will become a red giant as the outer hydrogen shell expands. This outer shell will expand to a size greater than that of the orbit of Mars, which is about 430 times larger than its current size.15
As the outer shell expands, the sun's luminosity will increase to about 20,000 times its current value. However, the surface temperature will lower to about 3,500 K while the core temperature reaches 100 million K.16 Earth will be bathed in more solar radiation and energy as the outer shell expands and nears Earth, thus casing the surface temperature of Earth to raise. It will continue to heat Earth until it is too dry and to hot for life to exist. Eventually, the burning hydrogen shell will envelope the Earth as well as Mercury, Venus, and Mars.
Now lets compare the article from above with the original one, which was written by Henry Norris Russell. This scientist didn't use in his predictions any carbon dioxide and green houses effects, but he based his words in pure scientific analysis and according to his own calculations.
It is important to notice that Russell was first against the conclusions of Cecilia Payne when she declared that stars are composed mainly with Hydrogen and Helium, and barely 1 percent of other elements. Russell finally conceded and he himself used later on the calculations made by Mrs. Payne. However (and this is food for another topic) recent reviews I have made of the composition of the Sun, can be interpreted that our star has more earth's alike elements in greater percent than the preached by the conventional scientific releases. And that "they" know about it, and are now trying to explain it with lots of superfluous hypothesis. Anyway, Russell perhaps wasn't "that wrong" after all about this issue.
Stellar Energy is a paper written by Henry Norris Russell, in 1939, a paper you can find in some science journals.
You can learn the different explanations of how stars' temperature and shinning are related, an explanation about atoms of hydrogen converting into helium, and lots of more scientific stuff, similar to the article presented above.
At one point, while describing the cooling process of our sun, Russell mentions its relationship with earth, and he predicted the warming of our planet without pointing by any means the industrial era in the world as the cause. This is because, sooner or later our planet will warms up anyway.
Of course, as a typical scientist he will use the millions years numbers for his calculations, because such is what any scientist must say in order to be accepted and his papers published in science journals and universities. That is called: "survival".
Here is the copy of page 12 of his article.
Enjoy.
