These are not things that will definitely happen. Rather ideas based on science and what has happened before. The point of doing this is not to scare people but to get them ready. By thinking about what could go scientists want to help people make better decisions and create a safer world for human civilization. Scientists study these possibilities to help human civilization.
Severe Climate Change Effects

Researchers say that extreme climate shifts could really mess up our food, water and shelter. If the temperature keeps going up and the weather keeps changing it may cause a lot of problems for people over time.
Global Resource Shortages

People need water, food and energy for civilizations to work. Scientists are saying that if we use much of these resources we will not have enough water, food and energy later on.
Large Asteroid Impact

Asteroids have hit Earth before. This is something that really scares people. Scientists are always watching the sky for space objects like asteroids. They do this closely but a big asteroid hitting Earth could be very bad for everyone.
Widespread Pandemic Events

History shows that diseases can really change the way societies work. Diseases have an impact on societies. Researchers are looking into how fast diseases can spread and make systems fail.
Nuclear Conflict Escalation

Scientists look at what happens over time when there is a war. If there are events they can hurt the land, the food we eat and the weather. Even if nuclear events are used a little they can still affect the world for a very long time like decades.
Advanced Technology Misuse

New technologies are really great. They bring a lot of good things.. At the same time technologies can also be very bad for us if we do not use them correctly.
Artificial Intelligence Risks

This can cause problems with our jobs the way we make decisions or even our safety. So it is very important that we develop Artificial Intelligence systems in a way to avoid any bad things from happening.
Super Volcano Eruptions

The Earth has big volcanoes that do not erupt very often. If one of the Earth’s volcanoes erupts, the ash from the Earth’s volcano could block the sunlight. This will affect crops all around the world.
Powerful Solar Storms

If we get our systems ready, for storms it can help cut down on the problems we have over time. This way solar storms will not affect our communication and energy grids much.
Slow Social Breakdown

Some researchers focus on gradual change rather than sudden events. Loss of trust, cooperation, and shared goals could weaken societies slowly. Strong communities and cooperation help prevent this outcome.
