Earth will likely remain a planet for another 4.5 to 5 billion years, but complex life will end much sooner, in about 1 billion years, when the Sun's increasing brightness makes the planet too hot and causes oceans to evaporate, leading to a runaway greenhouse effect and atmospheric deoxygenation. The planet itself will eventually be engulfed by the Sun when it expands into a red giant star, ending its existence as we know it.
As a result of these processes, multicellular life forms may be extinct in about 800 million years, and eukaryotes in 1.3 billion years, leaving only the prokaryotes.
By 2030 the odds now indicate that most of the planet will not have reached the Sustainable Development Goals, that global warming will continue, that the population will grow in the poorest regions and that there is not yet an alternative economic model that allows for a better redistribution of wealth.
This will destabilize the climate and lead to a surge in heatwaves, which are expected to affect nearly everyone on Earth – some 9.2 billion people – by 2050. Almost no corner of the planet will remain untouched by extreme heat.
Four billion years from now, the increase in Earth's surface temperature will cause a runaway greenhouse effect, creating conditions more extreme than present-day Venus and heating Earth's surface enough to melt it. By that point, all life on Earth will be extinct.
Humans Could Live For 1,000 Years by 2050—Ushering in the Dawn of 'Practical Immortality,' Futurists Say. Some experts warn that this radical change may remain out of reach for many, due to societal and economic challenges. Technology futurists foresee advances that will enable humans to live up to 1,000 years.
2030 is considered a critical deadline, a "point of no return," for climate action because scientists warn that surpassing 1.5°C (2.7°F) of global warming around that time risks triggering irreversible "tipping points," like melting permafrost releasing methane or Amazon rainforest dieback, leading to self-reinforcing warming loops that humanity can't stop, making catastrophic climate change much harder or impossible to avoid, even with future emissions cuts, according to reports from the UN IPCC, Science News and other experts.
China, India, and the United States will emerge as the world's three largest economies in 2050, with a total real U.S. dollar GDP of 70 percent more than the GDP of all the other G20 countries combined. In China and India alone, GDP is predicted to increase by nearly $60 trillion, the current size of the world economy.
By 2070, we'll see **smart cities** where AI plays a big role in running everything. AI will control traffic lights to reduce jams, self-driving cars will move safely, and public transport will be super efficient. AI will also help with managing waste and using energy, making cities greener.
While no country is immune to climate change, nations like Iceland, Canada, Norway, New Zealand, and Switzerland appear most resilient from a meteorologist's perspective. Their combination of geography, infrastructure, and preparedness makes them appealing choices in a changing climate.
Implication for Jesus's Return around A.D. 2030: If this model holds, A.D. 2030 would approximate the transition point between the 6,000 years of human history and the anticipated 1,000-year reign of Christ. This would mark a significant point for Jesus's return to establish a kingdom of peace on earth.
Australia and the 2030 Agenda for Sustainable Development
The 2030 Agenda is both a domestic and international agenda. It is well-aligned with Australia's foreign, security, development and trade interests - especially in promoting regional stability, security and economic prosperity.
The researchers also predict that by 2030, the three leading causes of illness will be HIV/AIDS, depression, and ischaemic heart disease (problems caused by a poor blood supply to the heart) in the baseline and pessimistic scenarios; in the optimistic scenario, road-traffic accidents will replace heart disease as the ...

No, no one has ever lived to be 200 years old with verified records; the oldest verified person was Jeanne Calment, who lived to 122 years and 164 days, but some scientists believe the first person to reach 200 may have already been born, given advancements in longevity research. Claims of much older ages, like Li Ching-yun (claimed 250+ years) or Peng Zu (claimed 800+ years), lack modern scientific verification.
So how long does Earth have until the planet is swallowed by the sun? Expected time of death: several billion years from now. But life on Earth will end much, much sooner than that. Earth will become unlivable for most organisms in about 1.3 billion years due to the sun's natural evolution, experts told Live Science.
# 1: Coronal Mass Ejections
Yes, this can happen to humanity on Earth… it has happened before! The very source of life for humanity is, indeed, our greatest threat.
The Global Challenges Foundation's 2016 annual report estimates an annual probability of human extinction of at least 0.05% per year (equivalent to 5% per century, on average). As of July 29, 2025, Metaculus users estimate a 1% probability of human extinction by 2100.
As the climate crisis remains a global priority, 2025 will likely be a year of significant progress in sustainability. Innovations such as carbon capture technology, green hydrogen production, and next-generation battery storage for renewable energy will begin to scale.
The People's Republic of China has received the most consistent coverage in the popular press of its potential superpower status, and has been identified as a rising or emerging economic and military superpower by academics and other experts.
The permanent members of the United Nations Security Council (also known as the Permanent Five, Big Five, or P5) are the five sovereign states to whom the UN Charter of 1945 grants a permanent seat on the UN Security Council: China, France, Russia, United Kingdom, and United States.
The Science Is Clear
It will never be too late to take meaningful action to protect people and the planet. However, decades of increasing carbon emissions from oil, gas and coal are harming the natural and social systems upon which all humanity depends, threatening devastation.
It aims to integrate the social, environmental and economic dimensions of sustainable development, plus the appropriate governance systems to ensure implementation. The SDGs identify broad goals across many areas covering all facets of sustainable development around the world.
Scientists are saying that by 2035 our climate will reach a point of no return. If global mean temperatures go to 2C or above, there will be no going back to how things once were. If this is reach possible unstoppable feedback loops could occur and make temperatures potentially go even higher.
