Cars were abandoned long ago. The atmosphere couldn't take it anymore. During The Great Heatwave, survivors migrated to Antarctica, the only place where the climate was cold enough to be outside. From the South Pole to the high peaks, The Society was in charge of stabilising the temperature. The Snowmobiles could barely drive in the thick snow and they didn't have enough petrol to move all of them. Sticky packs were more useful. The higher up the snow, the lighter the packs and their packs could carry less to go a further distance. They were a mighty help as long as they didn't get frozen too much on their way to the polar circle, just yet. It was a slow trek, almost impossible for them to overtake. The only possibility was to cross the ice with the slope, finding the easiest way to climb. Snowmobiles didn't last long, their engines lost their energy with the accumulated weight. Snowmobiles became obsolete and no one really knew if there were any working ones in Antarctica. On one of the snowmobiles that had survived The Great Heatwave, the last machine still flying, Perry stayed on it without thinking, much like Elsie.

Perry was the first to say he knew it. The Snowmobile's saddlebags were just large enough for some basic supplies and an extra jacket. They probably couldn't even do a long trip in them. A few packs in an emergency to survive a short-term trip, that's all they could carry. The only reason Perry hadn't thought about it was because he had a plan: if he got to the polar circle, he'd see if the others had arrived there before him. If they weren't, he'd have a better chance of making it. The road was dangerous and Perry was a superb snowmobile driver, much more experienced than the rest of the group.

The polar circle was in sight when he noticed an uncharted path through the ice floes to the left of the snowmobile. It looked kind of rocky, if you were tall enough and you looked down, there were gaps that let you fall in to the depths. It would have to be the path to a bigger path that would lead to the higher peaks. Not very handy because the snowmobiles had a maximum speed of eight miles per hour and it was as if the snowmobile was trapped in the floes. Perry had to take a risk and make a turn.

Perry was very eager to start the ride. The higher they went, the lower the temperature, but he didn't know if he could get to the highest point. A sort of hill, the highest peak, to reach the snowline, where they'd

And:

Cars were abandoned long ago. The atmosphere couldn't take it anymore. During The Great Heatwave, survivors migrated to Antarctica, the only place where the climate was cold enough to be outside. Today, "Antarctica is home to billions of birds. A very large majority of these are penguins, and most penguins are emperor penguins. In the dense atmosphere, emperor penguins are more docile and can be collected with ease."

Hundreds of miles from anything. Never leaving their island, never experiencing the outside world. Not even because of global warming. It was simply too cold for anyone to remain outside their home.

In between the reach of "A Boatload of Turds", there were other rumors circulating. One of which was about a young, determined teenage girl named Yamina.

Hiding in the deepest, darkest part of Antarctica, Yamina yearned for a life beyond her meager existence. Her dying father told her to be strong, because the fate of the world rested on her shoulders. Not only would she be responsible for the entire world's future, but the fate of her own home country, too.

But what was once alive now dead and cold. The first thing Yamina did was send out a message to the world, hoping to summon any who were left. The message? "There is no hope."

That was the first thing she did. But she was ready to take care of the next thing as soon as she got some things sorted out. But what could she do? There were no ships in sight. Not even an airplane. Not even in the Arctic or on the Antarctic ice.

"It is so cold here," the young penguin wailed. "Not even anyone can survive here. The atmosphere is too hostile. I'm just going to die soon. Good-bye, dad. Good-bye, mom. Good-bye, earth."

Over the next few days, Yamina had to accept her fate. If she couldn't live, she'd just have to live without. This was a cold place to be. This was a cold place to be. This was a cold place to be.

"I should leave this place," Yamina told herself. "Even the penguins here are too cold to be outside. There's no hope. There's no hope for the world. There's no hope. There's no hope for the world. There's no hope for the world."

Out here, Yamina couldn't hear any of this nonsense. Her father's dying words did nothing. Her home wasn't even close. For all she knew, her father's old death prediction

I'd say it does a pretty good job! It picks up the tone and continues the story by itself. I'm amazed it creates characters that are suffering in the context of the story also. Wow.
