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.In the climate whiplash phase that follows this relatively moderate scenario, global mean temperatures are likely to climb 2–3°C higher than today by 2200–2300 AD, then enter a cooling recovery phase lasting as much as 100,000 years.3.2°C
We are currently at around 1.1°C of warming and current climate policies are projected to increase global warming by 3.2°C by 2100. The IPCC has “very high confidence” that the risks and adverse impacts from climate change will escalate with increasing global warming.
How hot will Earth be in 3000 : By the year 3000, the warming range is 1.9°C to 5.6°C. While surface temperatures approach equilibrium relatively quickly, sea level continues to rise for many centuries.
Will Earth be habitable in 2100
Temperatures will be dangerously hot in more places and at more times than ever before. Less of Earth will be as agreeably habitable as in the past. Ecosystems and our relationships with ecosystems will continue to change, creating even more insecurity on the planet.
Will humanity make it to 2100 : The median expert predicted a 20% chance of a “catastrophe” (of any kind) and a 6% chance of human extinction by 2100. The median superforecaster was more optimistic, predicting a 9% chance of catastrophe and a 1% chance of extinction by 2100. The median expert put the chance of a nuclear catastrophe by 2100 at 8%.
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.
In a future with “moderate-high” greenhouse emissions and few efforts to mitigate these gasses, our world is truly transformed. First, there is an increase in heat. In this model (RCP 6.0), the world will be 2.2 degrees C higher in 2100 than today. And by 2500, the world will be a full 4.6 degrees C higher.
Is 1.5 degrees still possible
Natural variability in annual global temperatures around the long-term trend can reach a couple of tenths of a degree, meaning that an individual year might exceed 1.5°C even at today's level of human-made warming (around 1.2°C).Their research suggests that Earth's surface cooled from roughly 167o F (75o C) about 3 billion years ago to roughly 95o (35o F) about 420 million years ago. These findings are consistent with previous geological and enzyme-based results.According to the July 10, 2023 article of The Economist, scientists estimated a 12% chance of AI-caused catastrophe and a 3% chance of AI-caused extinction by 2100. They also estimate an 8% chance of Nuclear War causing global catastrophe and a 0.5625% chance of Nuclear War causing human extinction.

Will humans live 1,000 years : A molecular biogerontology professor believes we've only started to move toward holding off aging, and that humans will eventually have the potential to live for 1,000 to 20,000 years.
What will humans look like in 3000 : 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 Earth be like in 2500
Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.
While the effects of human activities on Earth's climate to date are irreversible on the timescale of humans alive today, every little bit of avoided future temperature increases results in less warming that would otherwise persist for essentially forever.As of March 26, 2024, Metaculus users estimate a 1% probability of human extinction by 2100.
How bad is global warming in 2024 : According to NCEI's Global Annual Temperature Outlook, there is a 22% chance that 2024 will rank as the warmest year on record and a 99% chance that it will rank in the top five.
