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.The LGP is part of a larger sequence of glacial and interglacial periods known as the Quaternary glaciation which started around 2,588,000 years ago and is ongoing.Because the Sun is not the only factor affecting global temperatures on Earth. Further, given our greenhouse gas emissions to date and those expected to come, the evidence points to the next “ice age” being averted altogether. What Is the Sun's Role in Climate Change
Are we overdue for an ice age : The last ice age, called the Wisconsin Glaciation, ended 18,000 years ago, and Earth is now in a warm interglacial. Warm periods can last about 15,000 years. All of which means, we are 1,000 to 3,000 years overdue for another ice age, which could be upon us.
Could global warming trigger an ice age
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.
Is global warming real : The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.
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. New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth's axis was approaching higher values.
Could global warming cause human extinction
The most recent report of the Intergovernmental Panel on Climate Change (IPCC)—a group of hundreds of scientists working with the United Nations to analyze climate change research from around the world—names many serious risks brought on by the warming of our planet, but human extinction is not among them.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.Hall said that the traditional explanation — and short answer — for why ice ages begin and end is a series of eccentricities and wobbles in the planet's orbit known as the Milankovitch cycles. Named after Serbian scientist Milutin Milankovitch, these cycles describe patterns in Earth's orbit and axial tilt. The geological record appears to show that ice ages start when the continents are in positions which block or reduce the flow of warm water from the equator to the poles and thus allow ice sheets to form. The ice sheets increase Earth's reflectivity and thus reduce the absorption of solar radiation.
Is the Earth getting hotter or colder : According to NOAA's 2023 Annual Climate Report the combined land and ocean temperature has increased at an average rate of 0.11° Fahrenheit (0.06° Celsius) per decade since 1850, or about 2° F in total. The rate of warming since 1982 is more than three times as fast: 0.36° F (0.20° C) per decade.
Can we survive global warming : Of course. Humans have survived the past century during which global mean temperature has risen by about 1C degree. We will survive another degree or so as well. However, with each increment in temperature the world we inhabit changes in response.
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. During the Mesolithic period (about 10,000 B.C. to 8,000 B.C.), humans used small stone tools, now also polished and sometimes crafted with points and attached to antlers, bone or wood to serve as spears and arrows. They often lived nomadically in camps near rivers and other bodies of water.about 46 degrees Fahrenheit

What did the last ice age look like : The Last Ice Age: Low Seas, Exposed Landmasses
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.
