Every year on June 5th we commemorate World Environment Day, proclaimed by the United Nations in 1972 on the occasion of the opening of the United Nations Conference on the Human Environment. The day has become the most important global platform for raising awareness on environmental issues and annually mobilizes governments, companies, scientific institutions and individuals to protect our planet.

In 2026, one of the most serious environmental challenges facing humanity is undoubtedly climate change. Although it has been discussed for decades, its consequences are becoming increasingly apparent today. Extreme heat, long-term droughts, devastating floods, forest fires and ecosystem disruption are becoming a common part of life in many regions of the world. World Environment Day therefore represents an opportunity not only to reflect on the current state of the planet, but also to find solutions that can mitigate the impacts of the climate crisis.

What is climate change?

Climate change refers to long-term changes in average temperatures and weather conditions on Earth. Although climate has changed naturally throughout history, current warming is occurring at an extremely rapid rate and is largely caused by human activity.

The main factor is the increase in the concentration of greenhouse gases in the atmosphere, primarily carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). These gases trap heat radiated by the Earth's surface and cause the so-called greenhouse effect. The natural greenhouse effect is essential for life on Earth, but its intensification due to the burning of fossil fuels, deforestation and intensive agriculture is leading to a dangerous increase in global temperatures.

Since the beginning of the Industrial Revolution, the average temperature of the planet has increased by approximately 1.2°C. While this number may seem small, it is a huge change in the global climate system, affecting the oceans, atmosphere, glaciers and biodiversity.

The consequences of climate change are already visible

Climate change is no longer a threat of the future. It is a reality of the present. The most prominent manifestations include:

Extreme temperatures

Record-breaking heat waves have been recorded on every continent in recent years. Heat waves cause health problems, increase mortality rates, especially among the elderly, and put pressure on energy systems due to the increasing need for cooling.

Drought and water shortage

Many regions are facing long-term shortages of rainfall. Droughts affect agricultural production, drinking water supplies and increase the risk of forest fires. Water scarcity is gradually becoming one of the most significant environmental and social problems of the 21st century.

Floods and extreme rainfall

A warmer atmosphere can hold more water vapor, leading to more intense rain and more frequent floods. Europe, including Slovakia, has experienced several devastating floods in recent years, causing widespread damage to infrastructure and property.

Melting glaciers and rising sea levels

The polar regions are warming faster than the rest of the planet. Melting glaciers and the Greenland ice sheet are contributing to rising sea levels, posing an existential threat to many coastal cities and island nations.

Threat to biodiversity

Many plant and animal species are unable to respond quickly enough to changing climate conditions. Habitat shifts, migration routes change and in some cases species become extinct. Biodiversity loss also weakens the ability of ecosystems to withstand further environmental changes.

Climate change and Slovakia

Although Slovakia is not among the largest producers of greenhouse gas emissions, the consequences of climate change are also felt here. The average annual temperature in Slovakia is increasing faster than the global average. Particularly significant are more frequent droughts, a decrease in snow cover in mountainous areas, and an increase in the occurrence of extreme meteorological phenomena.

With farmers facing weather extremes, forests weakened by a combination of drought and pests, and cities struggling with the heat island effect, climate change is not just an ecological problem, but also an economic and social challenge.

Solutions exist

The good news is that humanity has both the technology and the knowledge needed to mitigate climate change. Key actions include:

Transition to renewable energy sources

Generating electricity from the sun, wind, water or biomass allows for significant reductions in greenhouse gas emissions. Renewable sources are becoming increasingly available and economically competitive.

Increasing energy efficiency

Modernizing buildings, industrial processes and transportation systems can significantly reduce energy consumption. Every kilowatt-hour saved means lower emissions and lower costs.

Forest protection and restoration

Forests act as natural carbon sinks. Trees absorb carbon dioxide from the atmosphere and help regulate the climate. Protecting existing forests and restoring degraded lands are among the most effective climate measures.

Sustainable agriculture

Modern farming practices can reduce emissions while increasing the soil's ability to retain carbon. Regenerative agriculture, protecting soil from erosion and increasing soil organic matter are of particular importance.

Development of the circular economy

Extending product lifespans, recycling materials, and minimizing waste help reduce the consumption of natural resources and emissions associated with the production of new products.

The role of the individual

While addressing climate change requires systemic action from governments and industry, individuals also have a significant role to play. Everyone can contribute through their everyday choices.

This includes saving energy, using public transport, reducing food waste, supporting local products, responsible consumption and planting trees. Civic engagement and support for climate protection measures are also important.

Individual steps alone will not solve the climate crisis, but they create social pressure for broader changes and contribute to building a culture of sustainability.

World Environment Day as a call to action

World Environment Day is not just a symbolic event. It is a reminder that the future of the planet depends on the decisions we make today. Climate change is a global problem that transcends national borders, political systems and generations. Solving it requires the cooperation of scientists, politicians, business people and citizens.

At the same time, the climate crisis presents an opportunity to transform the economy towards cleaner technologies, more efficient use of resources and a healthier environment. Investing in climate solutions is not just a cost, but also an investment in future prosperity, energy security and quality of life.

On the occasion of World Environment Day, let us therefore remember a simple but important fact: Earth is the only home we have. Climate protection is not the task of future generations - it is the responsibility of all of us today. JRi&CO2AI
