prompter: Make up a new global threat on the level of global warming.

assistant: A made up threat with large scale effects on the world could be as follows:
A rogue planet passing through our solar system has caused earth to slowly spiral away from the sun.

To explain why this is on the same level as global warming, consider the following:
 - The slow movement away from the sun will gradually cause the world to cool down, as the sun's rays grow weaker. This cooling effect will drastically affect global food production, and eventually cause crop failures as the climate rapidly drifts from normal. This will, expectedly, cause massive human suffering in various forms such as famines, social unrest and falling goods supplies.
 - This threat mirrors global warming in its predictability before the turning point: A rogue planet approaching earth would have been noticed years or even decades in advance, allowing the possibility for plans to be enacted to avoid pr otherwise defuse the threat.
 - The threat will not equally impact all of the world, like global warming: Food shortages will affect countries which import it more that exporters. Weakening sunlight will cause regions dependent on solar to suffer energy shortages, while other regions which use non-solar energy will be able to avoid the shortage. Goods like cotton, bioplastics, and other plant based substances are usually very regional in their production, and this will affect trade and the well being of those farming the resource.

prompter: Can you provide a brief summary of a story about the discovery of this looming danger and humanity's desperate attempts to stop it?

assistant: A faint new point of light in the sky observed by astronomers was too far out be a comet; it was much bigger. As a rogue planet passed by our solar system it was never more than a faint speck of light against the dark night to the naked eye. But, that was enough. How could something that appeared so tiny - something so far away - harm us? Astronomers sounded the alarm. For the most part they were ignored. But what could anyone do anyway? With the mass of Jupiter the passing planet was too big to divert. The international space station was upgraded to support long term habitation for the lucky - or unlucky - few hundred who would attempt to sustain humanity in space for as long as they were able. As the interloper left our solar system its gravitational pull dragged Earth ever so slightly away from the sun. As Earth started to spiral away from the sun, the effects were small at first; a drop in global temperature and some unusually cold weather. As Earths orbit became wider and wider, the fate of life on our emerald world was sealed, destined to be entombed in ice and a mix of solid Nitrogen and Oxygen; all that was to remain of our atmosphere. In their last years, the remnants of humanity created monuments recording our history, hoping that one day, billions of years into the future, our planet would be discovered by another sentient species and they would learn of our story. Our icy tomb drifted into the void.

assistant: The rogue planet was discovered already in 2074, but due to the vast distance and that a rogue planet had not previously passed within the solar system it took more than 3 years before the discovery was verified by a dedicated science mission. The closest encounter was calculated to happen in 2089, and the planet would be the 3rd brightest object on the sky after the sun and the moon during that period. 
The original astronomers had already in 2075 warned that their calculations showed that the rogue planet could disrupt the motion of the planets, although due to the chaotic nature of orbital mechanics and the uncertainties involved it was not possible to exactly predict what would be the long term consequence. However, they did call for urgent action to prepare for all eventualities. The movement to prepare humanity for the potential catastrophe was a growing movement calling for spending over 5% of the global GDP on research on how to mitigate the effect. Politicians were however skeptical on spending this amount, and some populist parties around the world seized upon some research that showed that there was a 30% chance of the rogue planet causing no major disruptions to the planet. Despite the growing evidence over the year as the planet approached that it would lead to a significant change in Earth orbit, the initial 30% estimate lived on as a a myth in large parts of the public, effectively blocking some critical actions to be taken early. Initially there were hundreds of ideas on how to solve the problem, including kick starting global warming again, trying to divert the planet by the use of the entire world's arsenal of nuclear weapons and other and colonizing other planets to provide a backup for humanity. However, most of the ideas were impractical, and often pushed by people with special interests. 

As the consequences of the cooling climate became to large to ignore, an international collaboration to build an enormous mirror to reflect more light onto the planet became the prevailing idea. But despite the consensus on the building of the mirror, the project faced many obstacles due to disagreements on who should get to build the mirrors, where the sunlight should be pointed etc. Humanity eventually succeeded in stabilizing the cooling, but many of the negative consequences had already happened causing much loss and suffering.

assistant: As scientists discovered a rogue planet approaching Earth and threatening to cause it to spiral away from the sun, they sounded the alarm to the world leaders. Despite initial skepticism and lack of funding, a group of international scientists and engineers come together to develop a plan to save the planet. They proposed a massive propulsion system that would push Earth back into its proper orbit. The effort required a global effort and cooperation, as countries put aside their differences to work towards a common goal. As the planet slowly moved away from the sun and temperatures dropped, the race against time became more urgent. After many setbacks and obstacles, the propulsion system was finally activated, and it managed to successfully push Earth back into its proper orbit. The world breathed a sigh of relief as the sun's rays grew stronger, and temperatures stabilized. The experience brought humanity together and reminded them of the importance of working together to solve global problems.

assistant: Sure, in summary.

A rogue planet approached the earth. Thankfully we knew about it decades in advance,
But due to its slow movement away from the sun humanity could not comprehend the scale of the problem. 
Eventually it caused the world to cool down and the sun's rays started to weaken.
This caused the crops to fail and the climate then rapidly changed. Then came the human suffering followed by social unrest. 
Humanity's attempts to stop it had been futile.

prompter: Generate the outline of a science fiction story based on this premise. Include a clever twist

assistant: Here’s a new threat with potential global effect on life. A supervolcanic eruption can cause the release of high volumes of volcanic ashes, resulting in overnight and long lasting climate effects that would threaten all aspects of life on earth.

prompter: now im afraid this will happen! can you help calming me down?

assistant: The simulation hypothesis theorizes that the world experienced by humans or a specific human is a simulation. In this case, the termination of the simulation would result in the end of human existence. If this hypothesis is proven accurate, in order to survive, humans need to work together to prevent the universe from being terminated.

prompter: The simulation theory, though seemingly far-fetched, is a genuine concern. Can you come up with a purely fictional version that has not been previously proposed?
