How bad was the last ice age?
At the time of the LGM, the climate was cold and dry with temperatures that were 6 °C (11 °F) lower on average. Water levels in the ocean were more than 400 feet below what they are now, exposing large areas of the continental shelf.Yes, people just like us lived through the ice age. Since our species, Homo sapiens, emerged about 300,000 years ago in Africa, we have spread around the world. During the ice age, some populations remained in Africa and did not experience the full effects of the cold.The third ice age, and possibly most severe, is estimated to have occurred from 720 to 635 Ma (million years) ago, in the Neoproterozoic Era, and it has been suggested that it produced a second "Snowball Earth", i.e. a period during which Earth was completely covered in ice.

Why did the last ice age end so quickly : The overall trigger for the end of the last ice age came as Earth's orientation toward the sun shifted, about 20,000 years ago, melting the northern hemisphere's large ice sheets. As fresh meltwater flooded the North Atlantic Ocean, the Gulf Stream weakened, driving the north back into the ice age.

Did anyone survive the last ice age

Humans were able to survive the Ice Age due to evolution. Human brains developed to be larger, and humans began walking completely upright. With these advantages they were able to better plan ahead and to think about how to survive their situation.

What did Earth look like 20,000 years ago : 20,000 YEARS AGO. Last Glacial Maximum- a time, around 20,000 years ago, when much of the Earth was covered in ice. The average global temperature may have been as much as 10 degrees Celsius colder than that of today. The Earth has a long history of cycles between warming and cooling.

Human ancestors in Africa were pushed to the brink of extinction around 900,000 years ago, a study shows. The work, published in Science, suggests a drastic reduction in the population of our ancestors well before our species, Homo sapiens, emerged.

The scientific consensus is that there is a relatively low risk of near-term human extinction due to natural causes. The likelihood of human extinction through humankind's own activities, however, is a current area of research and debate.

How bad was ice age

The latest ice age peaked about 20,000 years ago, when global temperatures were likely about 10°F (5°C) colder than today. At the Pleistocene Ice Age's peak, massive ice sheets stretched over North America and Eurasia.In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth's northern half.Instead, Earth's natural cycles and greenhouse effects might delay the onset of the next ice age, expected within the next 10,000 to 100,000 years. Some theories suggest global warming could potentially trigger an ice age by disrupting ocean currents, specifically the Gulf Stream, leading to dramatic cooling in Europe.

At least five major ice ages have occurred throughout Earth's history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago.

How did humans look 10,000 years ago : 10,000 years ago: European males – 162.5cm (5 ft 4 inches). A dramatic reduction in the size of humans occurred at this time. Many scientists think that this reduction was influenced by global climatic change and the adoption of agriculture.

How did humans live 20,000 years ago : Life was very different for human societies 20,000 years ago. Humans hunted animals for food and had just started living in settlements. Unfortunately, very little evidence from this period exists.

Did humans exist 600000 years ago

Around 600,000 years ago, humanity split in two. One group stayed in Africa, evolving into us.

As of March 26, 2024, Metaculus users estimate a 1% probability of human extinction by 2100.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.

What will humans look like in 1000000 years : Perhaps we will have longer arms and legs. In a colder, Ice-Age type climate, could we even become even chubbier, with insulating body hair, like our Neanderthal relatives
