A Planet on the Brink: What Will the World Look Like in 2036 If Global Emissions Continue to Rise?

Climate change is a crisis that knows no borders. It cannot be stopped by political divisions or economic barriers, and it is becoming one of the forces that will shape the future of humanity. Rising emissions of greenhouse gases, especially carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O), are speeding up global warming and disturbing the Earth's natural systems. Climate summits and 'Net Zero' pledges have not yet produced real progress in ending the world's reliance on fossil fuels.

The effects of climate change are already a reality, visible in unprecedented heatwaves, devastating floods, prolonged droughts, melting glaciers and rising sea levels. If emissions follow their current trend, the coming decade may prove one of the most pivotal in human history, with environmental, economic, social and geopolitical problems all likely to worsen.

The climate system is highly sensitive to human-made change, as the climate scientist James Hansen has warned many times. The question is not only how much warmer the planet will be by 2036, but how much that warming will change human life.

1. Rising temperatures and more frequent heatwaves

Continued greenhouse gas emissions will trap more heat in the atmosphere and the oceans. As a result, extreme temperatures are likely to become more frequent, more severe and longer lasting.

Over the next decade, heatwaves may become more dangerous, especially in South Asia, the Middle East and parts of Africa. The risks will be highest for outdoor workers, the elderly, children and economically vulnerable communities. In some areas it may become unsafe to be outdoors at certain times of the day.

2. More intense extreme weather

A warmer atmosphere holds more moisture, so heavy rainfall will become more extreme and floods more destructive. At the same time, shifting rainfall patterns can deepen droughts in other areas.

Floods, cyclones, wildfires and droughts may worsen and set off chains of disasters around the world. Climate change is not directly responsible for every extreme weather event, but it makes many of them more likely or more intense.

3. Melting glaciers and rising seas

Glaciers and polar ice sheets are among the clearest indicators of global warming. If temperatures keep rising, ice will melt even faster and sea levels will continue to rise.

Coastal communities, especially in low-lying areas, will face greater risks from erosion, saltwater intrusion and flooding. Major coastal cities will need expensive protective infrastructure, and some communities may be uprooted altogether, losing their homes and their sense of belonging.

4. Threats to global food security

Agriculture depends heavily on temperature, water availability and the seasons. Higher temperatures, irregular rainfall and extreme weather can lower crop yields and disrupt food supply chains.

The impact could be especially severe in developing countries that rely heavily on farming. Lower production may push up food prices and deepen poverty and malnutrition. Food insecurity could become one of the most serious economic and humanitarian problems of the next decade.

5. Growing water scarcity

Changing rainfall, retreating glaciers, higher evaporation and longer droughts will put further pressure on freshwater resources.

Regions already under water stress may face longer dry periods. Competition over shared rivers and groundwater could intensify and lead to conflict between communities and neighbouring countries. Water security will therefore become an ever larger part of national security.

6. Loss of biodiversity and ecosystems

Biodiversity around the world is threatened by rising temperatures, ocean acidification, deforestation and habitat loss.

Coral reefs, forests, wetlands and mountain ecosystems are especially at risk, and species that cannot adapt or move quickly enough may go extinct. When ecosystems are destroyed, they also stop providing natural services such as pollination, carbon storage, soil protection and water purification.

7. Climate-driven migration

Floods, droughts, coastal erosion and falling agricultural productivity can force communities to abandon their homes.

Climate-driven displacement is likely to put extra strain on cities, housing, jobs and public services over the coming decade. Migration has many economic, political and social causes, but environmental stress will increasingly be one of them, especially in vulnerable regions.

8. Economic instability and widening inequality

Climate change threatens global economic stability. Extreme weather damages infrastructure, disrupts industrial production and transport networks, and raises insurance and reconstruction costs. Governments may have to divert money from development projects to disaster recovery and climate adaptation.

Developing countries, with less money, weaker institutions and greater exposure to climate disasters, will find it harder to recover. Richer nations will have more funds to invest in adaptation and resilient infrastructure. This unequal capacity could widen the economic gap between developed and developing countries.

9. Public health emergencies

Climate change is increasingly affecting public health. Extreme heat raises the risk of heat exhaustion, dehydration and cardiovascular stress, and changing environmental conditions can alter the spread of some infectious diseases.

Wildfires, air pollution, contaminated water and climate-related food shortages add further threats. Vulnerable countries may struggle to deal with environmental and medical emergencies at the same time, and the coming decade may test public health systems as never before.

10. Rising geopolitical tensions and climate security

Climate change is a threat multiplier for other political, economic and security problems. Shortages of water, food and energy, and the loss of habitable land, are likely to rise up the agenda of international relations, and tensions over these resources can grow within and between nations.

Negotiations between states that share transboundary rivers may become more complicated, and climate-driven displacement and scarcity could fuel political instability. Climate diplomacy, regional cooperation and environmental security will become an integral part of international relations.

11. The growing risk of climate tipping points

One of the most worrying aspects of global warming is the possibility of destabilising key parts of the Earth's climate system, such as the Amazon rainforest, ocean circulation, and the Greenland and Antarctic ice sheets.

Crossing some of these thresholds could bring changes that are irreversible and very hard to stop once they begin. Exactly when and how particular tipping points might be reached is still being researched, but the risk itself is a strong reason to limit greenhouse gas emissions now.

12. Pakistan: a case study in climate vulnerability

Pakistan shows how climate change threatens countries with a low capacity to adapt. It produces only a small share of global greenhouse gas emissions, yet it is highly exposed to climate disasters.

The devastating floods of 2022 exposed the fragility of Pakistan's agriculture, infrastructure, housing and public health system. By 2036, these challenges are likely to grow with further warming, changing rainfall, glacial hazards and water shortages.

The Indus river system, which sustains Pakistan's agriculture and livelihoods, is especially vulnerable. Changes in rainfall, snow and glacier behaviour can make water management and agricultural planning harder, while cities may face more extreme heat, water scarcity and pressure on public services.

Meeting these challenges requires climate-resilient infrastructure, better water governance, sustainable agriculture, stronger disaster preparedness and more investment in renewable energy. Adaptation must become a regular part of development planning, not just a reaction to environmental catastrophes.

13. The way forward

Past emissions will keep affecting the climate system, but the future is not fixed. Decisive mitigation and adaptation can greatly reduce future climate risks, and the world community needs to move beyond diplomatic statements to action. The following measures are essential:

i. Speed up the renewable energy transition: governments need to cut their reliance on coal, oil and gas, and promote renewable energy, particularly solar, wind and hydropower.

ii. Strengthen international climate pledges: countries need to turn their Nationally Determined Contributions (NDCs) under the Paris Agreement into concrete policies and binding commitments.

iii. Protect and restore nature: climate policy should place greater emphasis on conserving forests and restoring ecosystems and wetlands.

iv. Cut methane: governments need to tackle methane leaks from the fossil fuel industry, livestock farming and waste management.

v. Invest in adaptation: flood-resistant infrastructure, heat action plans, sustainable irrigation and early-warning systems will reduce vulnerability to climate disasters.

vi. Mobilise climate finance: developed countries and international financial institutions need to increase financial and technological support for vulnerable developing countries.

vii. Promote international cooperation: climate change is a global problem that demands a collective response, and global governance must keep environmental cooperation a priority.

Conclusion

The next ten years will be a critical period that decides whether humanity can balance economic growth with environmental protection. If greenhouse gas emissions stay high, the world of 2036 will likely see more frequent heatwaves, worsening water and food insecurity, biodiversity loss, economic instability and climate-driven displacement. These impacts will not be shared equally: developing countries and economically vulnerable communities are likely to suffer a disproportionate share.

Yet the future is not out of human hands. Renewable energy, technological innovation, sustainable development, environmental protection and international cooperation offer realistic ways to change course. What humanity needs is not another ten years of political statements, but ten years of concrete action.

Climate change is not only an environmental issue; it is also a question of economic justice, human security and responsibility to future generations. The world must accept that the cost of doing nothing is far higher than the cost of protecting the planet. The question is no longer whether climate change will reshape our world, but whether we will act in time to decide how.
