The world is approaching a dangerous climate threshold, and the consequences of delayed action are becoming increasingly difficult to ignore. Rising temperatures, intensifying extreme weather events, melting glaciers, deteriorating ecosystems and mounting pressure on natural resources are exposing the vulnerability of human societies and the natural environment. Despite decades of international negotiations and ambitious climate commitments, global efforts to reduce greenhouse gas emissions remain far below what science demands.
The warning signs are becoming more serious. Current government policies put the world on course for approximately 2.8°C of global warming above pre-industrial levels by 2100. Against this alarming background, the European Union is proposing new rules for preparing for a 3°C world – when the countries are developing their climate policies, infrastructure plans and investment decisions. The proposal reflects a growing recognition that governments must prepare for a much hotter world, even as they continue working to prevent it.
The message is clear: climate action can no longer depend exclusively on reducing emissions. Preparing for a 3°C world is must for humanity to simultaneously strengthen its ability to understand, withstand and adapt to the environmental changes already unfolding.
Preparing for a 3°C World: Adaptation Can No Longer Wait
For decades, international climate discussions have largely focused on limiting global warming through emission reductions, renewable energy expansion and commitments to achieve net-zero emissions. These efforts remain essential. However, the accelerating pace of climate impacts has made another priority equally important: preparing communities, economies and ecosystems for the warming that can no longer be avoided entirely.
The proposed European approach represents an important shift towards climate-resilient policymaking. Rather than planning infrastructure and economic development around relatively moderate temperature increases, govts would have to consider the consequences of a potential 3°C rise.
Such a scenario would have profound implications for nearly every aspect of life. More frequent and intense heatwaves could threaten public health and agricultural productivity. Changing rainfall patterns could increase drought risks in some regions while intensifying flooding in others. Rising temperatures would accelerate glacier retreat, disturb freshwater availability and place additional pressure on already vulnerable ecosystems.
For countries such as Pakistan, these risks are particularly concerning. The country’s dependence on the Indus River system, Himalayan and Karakoram glaciers, seasonal monsoon rainfall and climate-sensitive agriculture makes it highly vulnerable to changing environmental conditions. More intense rainfall, prolonged heatwaves, glacier-related hazards and water insecurity could threaten communities, food production and economic stability.
Preparing for a 3°C world should therefore mean investing in climate-resilient infrastructure, restoring natural ecosystems, improving water management, strengthening early warning systems and protecting vulnerable communities.
Nevertheless, adaptation must never become an excuse for abandoning emission reductions. Preparing for a hotter world is necessary, but allowing temperatures to rise further would make adaptation increasingly expensive and, in some places, impossible.
NASA’s Carbon Monitoring: A Clearer Picture of Earth’s Changing Atmosphere
While governments are reconsidering their climate strategies, scientific advancements are offering new ways to understand the forces driving global warming. One particularly important development comes from NASA’s Orbiting Carbon Observatory-2 (OCO-2) and Orbiting Carbon Observatory-3 (OCO-3). These sophisticated space-based instruments observe sunlight reflected from Earth’s surface and use advanced scientific algorithms to estimate atmospheric carbon dioxide concentrations.
OCO-2 was launched in 2014, while OCO-3 was installed aboard the International Space Station in 2019. Together, the instruments collect more than a million observations each day, providing scientists with an increasingly detailed picture of how carbon dioxide is distributed throughout the atmosphere.
Their observations have helped researchers investigate the movement of carbon between the atmosphere, oceans, vegetation and land ecosystems. They have also improved understanding of how natural events, including wildfires, droughts and El Niño, influence the global carbon cycle.
Now, researchers have developed an improved data-processing algorithm that has produced a more accurate global atmospheric carbon dioxide record covering September 2014 to 2026. The improvements include better instrument calibration and more sophisticated treatment of factors such as clouds, atmospheric aerosols and sunlight reflected from the ocean. The resulting measurements generally agree more closely with highly accurate observations from ground-based monitoring stations. The close agreement between OCO-2 and OCO-3 also strengthens confidence in the reliability of the observations.
Published in the journal Earth and Space Science, the research represents an important advancement in atmospheric carbon monitoring. Perhaps most significantly, the improved record allows scientists to examine changes in atmospheric carbon dioxide month by month rather than relying exclusively on annual measurements.
This can help reveal how extreme environmental events influence carbon accumulation and how effectively natural ecosystems absorb and release carbon. Such information is essential for understanding the changing carbon cycle and evaluating the effectiveness of climate policies.
After all, meaningful climate action begins with understanding what is happening to our atmosphere. Better measurements enable researchers and policymakers to identify emerging trends, assess environmental changes and make more informed decisions.
Fossil Fuel Subsidies: Financing the Destruction of Nature
Scientific knowledge alone, however, cannot solve the climate crisis. The way governments allocate public money also plays a decisive role in determining the future of the planet. At the United Nations biodiversity summit, COP17, in Yerevan, Armenia, UN Secretary-General António Guterres delivered a powerful message about the contradiction between environmental commitments and government spending.
He described fossil fuel subsidies as a form of subsidising suicide, urging governments to stop supporting activities that accelerate global warming and biodiversity destruction. His criticism highlights a troubling reality: while nations repeatedly promise to protect the environment, significant public financial resources continue to support industries and activities that undermine those commitments.
Fossil fuel subsidies encourage continued dependence on coal, oil and gas, prolonging the use of energy sources responsible for substantial greenhouse gas emissions. Their environmental consequences extend beyond atmospheric warming. Fossil fuel extraction, transportation and processing can destroy habitats, contaminate water resources, degrade landscapes and place additional pressure on wildlife.
The problem is not limited to fossil fuels. Intensive agricultural practices, environmentally damaging mining and unsustainable resource extraction can also receive public financial support despite their harmful consequences for ecosystems.
Under the Kunming-Montreal Global Biodiversity Framework adopted in 2022, countries committed to identifying and eliminating, phasing out or reforming incentives harmful to biodiversity. The international target includes reducing such incentives by at least $500 billion annually by 2030. However, progress remains insufficient.
Guterres has urged governments to redirect financial resources towards activities that benefit people and the planet rather than supporting industries that damage natural systems. This is an important economic and environmental argument. Public money should encourage renewable energy, ecosystem restoration, sustainable agriculture, forest protection and climate-resilient development instead of reinforcing dependence on environmentally destructive activities. As Guterres emphasised, nature cannot thrive on good intentions alone.
Climate Change and Biodiversity Loss Are Interconnected Crises
One of the greatest mistakes in environmental policymaking is treating climate change and biodiversity loss as separate challenges. In reality, they are deeply interconnected. Rising temperatures alter habitats, disturb migration patterns, increase pressure on freshwater ecosystems and threaten species already struggling with habitat destruction and human activities.
At the same time, healthy ecosystems provide some of the most effective natural defences against climate change. Forests absorb and store carbon, wetlands regulate water flows, mangroves protect coastal communities, and healthy soils support food production while storing substantial quantities of carbon. Biodiversity also strengthens ecosystem resilience, helping natural systems withstand environmental disturbances. Destroying these ecosystems while spending public money on activities accelerating climate change creates a dangerous environmental degradation cycle.
This is why climate policies must recognise the value of nature-based solutions. Protecting existing forests, restoring degraded landscapes, conserving wetlands and promoting sustainable land management are not optional environmental luxuries. They are essential investments in humanity’s long-term security.
The Way Forward: Turning Climate Knowledge into Meaningful Action
The developments surrounding European climate adaptation proposals, NASA’s improved carbon monitoring and the United Nations’ call to end harmful subsidies point towards a common conclusion: the world needs a more integrated approach to environmental protection.
Governments must develop climate policies that address both present vulnerabilities and future risks. Scientific institutions need sustained support to improve climate observations and provide reliable information. Financial systems must be reformed so that public investments support environmental sustainability rather than undermine it.
For developing countries, climate finance, technology transfer and international cooperation are particularly important. Nations that have contributed relatively little to historical greenhouse gas emissions often face some of the greatest consequences of a warming planet. They need adequate resources to protect communities, strengthen infrastructure and conserve their natural heritage.
Pakistan and other climate-vulnerable countries must also make ecosystem protection central to their development strategies. Restoring forests, protecting river systems, improving agricultural practices, conserving biodiversity and managing freshwater resources sustainably can strengthen resilience against future environmental shocks.
Ultimately, the challenge is not simply to prepare for a 3°C world. It is to prevent the planet from reaching that dangerous threshold while protecting people and ecosystems from the warming already underway.
A Warming Planet Demands a New Approach to climate action: We Must Prepare for the Future Without Surrendering It
Nature is not an unlimited resource that humanity can exploit without consequences. The atmosphere, forests, rivers, oceans and countless living organisms form an interconnected system that sustains life on Earth. When one part of this system is disturbed, the consequences can spread far beyond their original boundaries.
The warnings are now unmistakable. Governments are being urged to plan for a hotter future, scientists are improving our ability to monitor atmospheric carbon, and international leaders are questioning the continued financial support of industries that damage the environment.
These developments must lead to more than statements, scientific publications and international pledges. They must inspire practical decisions, responsible investments and a genuine transformation in humanity’s relationship with nature. We cannot control every natural process, but we can reconsider the choices that intensify environmental destruction. We can protect forests instead of clearing them, restore ecosystems instead of degrading them, invest in clean energy instead of perpetuating fossil fuel dependence, and prepare communities instead of leaving them exposed to predictable climate risks.
The future of our planet will not be determined by promises alone. It will depend on whether humanity is finally prepared to align its economic ambitions, scientific knowledge and political decisions with the natural systems that make life possible.
