By 2060, Earth will be home to roughly 10 billion people, dealing with shrinking Arctic ice, lower crop yields, strained water supplies, and accelerating species loss. No single catastrophic event is predicted for that year, but the convergence of climate change, population growth, and resource pressure will reshape daily life on every continent. Here’s what the science projects.
A Planet of 10 Billion People
The United Nations projects the global population will reach 9.8 billion by 2050 and 11.2 billion by 2100, putting the 2060 figure somewhere around 10 billion. Half of that growth between now and mid-century will be concentrated in just nine countries: India, Nigeria, the Democratic Republic of the Congo, Pakistan, Ethiopia, Tanzania, the United States, Uganda, and Indonesia. Twenty-six African countries are expected to at least double their current populations by 2050, making sub-Saharan Africa the fastest-growing region on the planet.
Europe, by contrast, will likely be shrinking. Birth rates across the continent remain well below replacement level, hovering around 1.6 births per woman. Immigration can soften the economic effects of aging populations, but it won’t fully offset the decline. The result is a demographic tilt: younger, larger populations in Africa and South Asia, and older, smaller ones in Europe and parts of East Asia. That imbalance will drive migration patterns, labor markets, and geopolitical power for decades.
Most of these billions will live in cities. The UN estimates that 68% of the world’s population will be urban by 2050, and that share will only grow through the 2060s. By 2030 alone, 43 megacities will have more than 10 million residents each. The infrastructure demands of housing, feeding, and providing water and energy to these dense urban centers will be one of the defining challenges of mid-century life.
An Arctic Without Summer Ice
The Arctic Ocean will almost certainly experience its first ice-free September before 2060. A 2023 study in Nature Communications found that the first summer without meaningful sea ice could arrive as early as the 2030s to 2050s, regardless of which emissions path the world follows. That means even aggressive climate action won’t prevent it. The difference emissions make is what happens after: under higher warming scenarios, ice-free conditions extend into earlier summer months and last longer each year.
Losing Arctic summer ice matters far beyond the polar region. Sea ice reflects sunlight back into space. Without it, the dark ocean absorbs more heat, which accelerates warming in a feedback loop. This disrupts jet stream patterns, influencing weather systems across North America, Europe, and Asia. It also opens new shipping routes and resource extraction opportunities in the Arctic, raising fresh geopolitical tensions among nations bordering the region.
Declining Crop Yields
Food production will take a measurable hit. A study published in Scientific Reports modeled what happens to staple crops under a moderate warming scenario (about 1°C of additional warming by 2060, without adaptation measures). The results: maize yields drop by 10%, wheat by 6.5%, and rice by 2.8%. Those percentages may sound modest, but applied to a global food system feeding 10 billion people, they translate to hundreds of millions of tons of lost grain.
The losses won’t be evenly distributed. Tropical and subtropical regions, where many of the world’s poorest and fastest-growing populations live, face the steepest declines. Higher-latitude countries like Canada and Russia may actually see some gains as growing seasons lengthen, but those gains don’t compensate for losses elsewhere. Adaptation measures like drought-resistant crop varieties, improved irrigation, and shifts in planting seasons can blunt the impact, but they require investment and infrastructure that many vulnerable countries lack.
Water Stress Reaches Billions
Over half the world’s population is projected to live in water-stressed areas by 2025, and those numbers will increase significantly through 2060 as climate change intensifies and populations grow. Water stress means demand for freshwater regularly approaches or exceeds available supply. It shows up as rationing, depleted aquifers, shrinking rivers, and conflict over shared water resources.
The most affected regions include North Africa, the Middle East, Central Asia, and parts of India and China. But water stress isn’t limited to traditionally dry areas. Changing rainfall patterns mean that regions accustomed to reliable water supplies may face new seasonal shortages. Meanwhile, glaciers that feed major river systems in Asia and South America are retreating, threatening the long-term water supply for billions of people who depend on snowmelt and glacial runoff.
Species Loss Accelerates
Biodiversity will be under serious pressure by 2060, though the scale depends heavily on how much the planet warms. Under current international emissions commitments, which put the world on track for about 2.7°C (4.9°F) of warming, roughly 1 in 20 species worldwide faces extinction risk by the end of the century. If emissions are managed in line with the Paris Agreement, that number drops to about 1 in 50, or an estimated 180,000 species. Under the worst-case scenario of 5.4°C (9.7°F) of warming, nearly one in three species could be threatened.
By 2060, the world will be somewhere along these trajectories, with many species already in steep decline even if they haven’t yet vanished entirely. Habitat loss from expanding agriculture, urbanization, and rising temperatures will push wildlife into smaller and more fragmented ranges. Ocean ecosystems face a parallel crisis from warming waters, acidification, and oxygen depletion. Coral reefs, which support roughly a quarter of all marine species, are expected to suffer severe bleaching events annually under mid-century warming levels.
What Separates the Scenarios
The range of outcomes for 2060 is wide, and emissions decisions made in the next decade are the single biggest factor determining where on that range the world lands. In a lower-emissions scenario, crop losses are smaller, water stress grows more slowly, and species loss stays closer to the lower projections. In a higher-emissions world, those impacts compound: food shortages drive migration, which strains urban infrastructure, which deepens inequality, which makes adaptation harder.
Technology and policy choices also matter. Advances in desalination, vertical farming, renewable energy, and carbon capture could soften many of these projections. But the research consistently shows that the scale of change required is enormous. The difference between a manageable 2060 and a destabilizing one is not a matter of inventing one breakthrough technology. It’s a matter of deploying solutions that already exist at a speed and scale that matches the problem.
