(It also considered scenarios in between.) In 10,000 years, if we totally let it rip, the planet could ultimately be an astonishing 7 degrees Celsius warmer on average and feature seas 52 meters (170 feet) higher than they are now, the paper suggests.
This suggests some surprising things about our future. We will likely live longer and become taller, as well as more lightly built. We'll probably be less aggressive and more agreeable, but have smaller brains. A bit like a golden retriever, we'll be friendly and jolly, but maybe not that interesting.
Just as our planet existed for over 4 billion years before humans appeared, it will last for another 4 billion to 5 billion years, long after it becomes uninhabitable for humans.
In 50,000 years, we will almost certainly face an epic catastrophe that will change the planet forever. The catastrophe could take the form of an asteroid or a comet, which, upon striking the Earth, would end life as we know it.
In 100 years, the world's population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
Though the climate of Earth will be habitable in 2100, we will be experiencing new extremes. Each decade will be different from the previous and next decade. The climate future could be quite bleak.
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
There are fears that a powerful geomagnetic storm in the year 2025 can destroy the Earth. An NYU professor believes there is a likelihood that such an event can happen.
By 2050, due to the lack of greenery, concrete forests will be made in its place. At this time there will be such a shortage of land that many big buildings will be cultivated to meet the needs of food and drink. According to a US report, the sea level will increase by 2050.
Will humans survive? Yes, almost certainly, but the factors that determine the outcome are so immensely complex that our blunt and instrumental efforts are almost meaningless. The only thing that makes a difference is the combined impact of all individual animals including humans.
There are three times in history during which humans nearly went extinct. Here's what threatened us, and how we survived.
Heatwaves will be more frequent and long-lasting, causing droughts, global food shortages, migration, and increased spread of infectious diseases. Moreover, as the polar ice will melt, sea levels will rise substantially, affecting a large number of coastline cities and as many as 275 million of their inhabitants.
"Someone could even live to 1,000, but the probability of that is one in 1 quintillion," Milholland added. (If all the humans who have ever lived in the history of the species were totaled up, we'd still fall short of 1 quintillion.)
🦅 Humans evolving to fly is incredibly unlikely due to our existing physical makeup and the lack of evolutionary benefit. 🐒 Humans are part of the simians, a larger group of primates that includes monkeys, lemurs, and apes.
Broadly speaking, evolution simply means the gradual change in the genetics of a population over time. From that standpoint, human beings are constantly evolving and will continue to do so long as we continue to successfully reproduce.
The report warns that, by 2040, global temperatures are expected to rise 1.5 degrees Celsius above pre-industrial levels, meaning that most people alive today will see the dramatic effects of climate change within their lifetime.
The world population is expected to reach 8.5 billion people by 2030. India will overtake China as the most populated country on Earth. Nigeria will overtake the US as the third most populous country in the world. The fastest-growing demographic will be the elderly: 65+ people will hit one billion by 2030.
Predicted and scheduled events
May – The 2028 Eurovision Song Contest is scheduled; the location is typically determined by the previous year's winner. May 8 – The 2028 Philippines Presidential Election will be held. July 14 – July 30 – The 2028 Summer Olympics will be held in Los Angeles, California, US.
Worldwide there are roughly two new mutations for every one of the 3.5 billion base pairs in the human genome every year, says Hodgson. Which is pretty amazing - and makes it unlikely we will look the same in a million years.
If we used a time machine to travel back to a prehistoric period, the earliest we could survive would be the Cambrian (around 541 million years ago). Any earlier than that and there wouldn't have been enough oxygen in the air to breathe.
So what's going to happen in 2045? It's pretty likely that robots and artificial technology will transform a bunch of industries, drone aircraft will continue their leap from the military to the civilian market, and self-driving cars will make your commute a lot more bearable.
2100: Either uninhabitable or beginning to repair
Over the coming two decades, extreme weather is set to disrupt society with increasingly severe bushfires, drought and storms. The good news is by the end of the century, living on Earth could actually be more pleasant than it is today.
A new book examining the forces shaping the future of global migration forecasts Michigan as the best place in the world to live in 2050. How can the world collaborate to minimize temperature rise to save as many lives as possible?
By 2100, the projected warming is between 1.2°C and 4.1°C, similar to the range projected by AOGCMs. A large constant composition temperature and sea level commitment is evident in the simulations and is slowly realised over coming centuries. By the year 3000, the warming range is 1.9°C to 5.6°C.
