Is This It?

The year is 11120, and it could very well be the last one. The end of the world is coming. We all knew it. Scientists discovered that before the 20th century, a long time ago.
For the past 500 years, give or take, the winters have been getting significantly milder, the summers hotter. The big bodies of water started to dry up, and crops became harder to grow. The meagre supply of food we do have can only sufficiently feed half of us. We have to keep moving for fear of Solar Flares. They hit the ground now, instead of staying in the solar atmosphere, and release radiation, which kills more of us. I am not sure why we bother to stay alive, after all, the sun is getting closer and there's nothing we can do about it. Maybe it's instinct, or maybe it's something else.
