Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
Scientists estimate modern humans have been around about 200,000 years, so that should give us at least another 800,000 years. Other scientists believe we could be here another two million years…or even millions of years longer. On the other hand, some scientists believe we could be gone in the next 100 years.
Jean-Marc Salotti calculated the probability of human extinction caused by a giant asteroid impact. It is between 0.03 and 0.3 for the next billion years, if there is no colonization of other planets.
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.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
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.
According to a US report, the sea level will increase by 2050. Due to which many cities and islands situated on the shores of the sea will get absorbed in the water. By 2050, 50% of jobs will also be lost because robots will be doing most of the work at that time. Let us tell you that 2050 will be a challenge to death.
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. We will need to figure out ways of how to accommodate 100+ people at work.
The fossil record indicates that Homo sapiens has been around for 315,000 years or so, but for most of that time, the species was rare—so rare, in fact, that it came close to extinction, perhaps more than once.
Based on known risks, the really cataclysmic ones, those that might exterminate us as a species, are fairly rare. Based on what we know today, it would be very unlikely that we wouldn't be around in the year 3000. There certainly would be bad times, but some of us would get through it. That leaves unknown risks.
However, using information gathered by paleontologists and the history of evolution, it's been estimated that 99.9% of all species are extinct. That's not all of the species living here on the Planet today. It's actually of all the species who have lived on Earth at all.
Habitat loss due to deforestation, agricultural practices and urbanization is the leading cause of extinction across the world. The other options are also causes but the major cause of extinction is habitat loss.
They would still probably be small, scrawny, and very generalized. But instead, the mammals were able to evolve and diversify and, well, ultimately, millions of years later, become some humans. So perhaps we would not have been here if it weren't for this extinction event 65 million years ago.
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.
Dogs come in a variety of breeds, some of which you may never have heard of before. While there are over 350 recognized dog breeds by International Canine Federation standards, extinct dogs have come and gone over the years. Sadly, quite a few dog breeds may no longer exist in the modern world.
Co-lead researcher Shimona Kealy said these people probably travelled through Indonesia's northern islands, into New Guinea and then Australia, which were part of a single continent between 50,000 and 70,000 years ago, when sea levels were 25-50 metres below the current level.
The Toba eruption has been linked to a genetic bottleneck in human evolution about 70,000 years ago; it is hypothesized that the eruption resulted in a severe reduction in the size of the total human population due to the effects of the eruption on the global climate.
Neanderthals, Denisovans, Homo erectus all vanished, leaving just Homo sapiens.
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.
The study, published Jan. 30 in Proceedings of the National Academy of Sciences, provides new evidence that global warming is on track to reach 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial averages in the early 2030s, regardless of how much greenhouse gas emissions rise or fall in the coming decade.
2070 will be marked by increased acidification of oceans and slow but remorseless sea-level rise that will take hundreds if not thousands of years to reverse – a rise of more than half a metre this century will be the trajectory. “It's a very different world,” Thorne says.
2050 is only about 30 years from now, which means it's close enough that we can imagine it happening, but far enough away that we can't confidently say what it will look like. Maybe that's why 2050 is the year Kaspersky Lab chose to envision for its new futuristic, interactive map.
Since 1880, average global temperatures have increased by about 1 degrees Celsius (1.7° degrees Fahrenheit). 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.
