Temperature rise

Temperature rise refers to the increase in the average temperature on the Earth’s surface over a given period of time. This phenomenon, known as global warming, is one of the main consequences of climate change and has a serious impact on the climate system, the environment and society.

Causes of the rise in temperature:

1. Greenhouse gas emissions: The main reason for the rise in temperature is the release of greenhouse gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) into the atmosphere. These gases are mainly caused by human activities such as the burning of fossil fuels, land use changes and agriculture.
2. Enhanced greenhouse effect: The increased concentration of greenhouse gases in the atmosphere enhances the natural greenhouse effect by increasing the ability of the Earth’s atmosphere to absorb infrared radiation and radiate it back to the Earth’s surface. This causes temperatures to rise.
3. Changes in land use and land cover: The conversion of forests to agricultural land and urban areas affects the albedo (reflectivity) of the Earth’s surface and contributes to warming.

Effects of rising temperatures:

• Melting glaciers and polar ice caps: The rise in average temperatures leads to increased melting of glaciers and ice sheets in polar regions and contributes to sea level rise.
• More frequent heat waves: Rising temperatures lead to more frequent and intense heat waves, which can cause health problems.
• Shifting climate zones: Plants and animals must adapt to changing climatic conditions, leading to shifts in climate zones and ecosystems.
• Changes in precipitation patterns: The rise in temperature can lead to changes in precipitation patterns, resulting in droughts or floods.
• Oceanic impacts: Rising ocean temperatures impact marine biodiversity, coral bleaching and the intensity of tropical storms.

Combating the rise in temperature:

Combating rising temperatures requires action to reduce greenhouse gas emissions, promote renewable energy, energy efficiency and sustainable land use. International agreements such as the Paris Agreement aim to limit warming to below 2 degrees Celsius above pre-industrial levels and to drive adaptation to the already unavoidable changes. Tackling the rise in temperature requires global cooperation and the involvement of governments, businesses and individuals.
