Isn't anyone worried that years from now the sun would melt objects or even life forms?

Question

As we all know, the sun gets hotter every day, how hot will it be in the year 2020 or more. different parts of the world experience different tempreture, some get skin cancer, some die sooner than others, etc all this linked to the sun, yet at this modern time, we still harm our ozone layer with toxic cemicals and gas. its between two things, 1 pepole just dont care, 2, they are not aware. i think its no. 1 so, the real question is do you think its possible for the sun to melt us in the future, and do you think you/we are doing enough to prevent this from happening.

Answer 1

I think you may be a little confused. It is true that the sun will keep expanding until, eventually, it will engulf the Earth. This, of course, would result in the death of all life on this planet. However, this will probably happen billions of years from now. Part of the reason why the effects of the sun are often seen is because we have been destroying the ozone layer, which is our natural barrier against the sun's rays. I think that it's too late to completely stop the rapid deterioration of the ozone layer. We, the human race, have done too much damage. At this point, all we can do is hinder the decaying process. Unfortunately, major countries still refuse to limit their chemical outputs. China is planning on building 500 more power plants, which would result in a massive increase in pollution. Hopefully, by the time the sun manages to inflict dire harm, the human race will have already colonized another planet. The real question is, do we really deserve it? Do humans deserve to have this opportunity?

Answer 2

It 'gets hotter' at an averaged rate of around 0.000000005% per year. Compared to the cyclic variations it goes through, it's a trivial amount, and balanced to some degree by the general cooling of the Earth itself. In addition, as it throws off more mass, Earth's orbit also gets pushed away (or let go) slightly, mitigating this effect even further.

In a nutshell, this isn't a concern for hundreds of millions of years, in comparison to the other ecological problems going on.

Answer 3

You are mixing different problems:
1) The global warming
2) The destruction of the ozone layer.

Those problems aren't connected in a simple relation, though some chemicals can be a cause of both effects.

And it might relax you a bit, that people aren't going to 'melt' anyway.

Still at the moment its certainly done not enough in both concerns.

Answer 4

The sun does not get hotter every day. But it does get VERY SLIGHTLY hotter every million years. In 500 million years it will be a problem, but not by the year 2020. It may even be COOLER in 2020. It gets VERY SLIGHTLY warmer and then cooler again every 11 years.

Answer 5

Before the sun burns out in 4-5 billion years, the Andromeda galaxy will most likely collide with us in about 3 billion yrs, so it probably wont be an issue

Answer 6

People don't melt, they char and burn.

But don't worry, the sun won't scorch the earth for billions of years. Just remember to wear sunblock and don't get burned.
