aüvegházhatású

The term "üvegházhatású" is the Hungarian word for "greenhouse gas." Greenhouse gases are atmospheric gases that absorb and re-emit infrared radiation. This process is the fundamental mechanism behind the greenhouse effect, which warms the Earth's surface.

The most significant greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O). Other gases, such as ozone (O3) and chlorofluorocarbons (CFCs), also contribute. While water vapor is the most abundant greenhouse gas, its concentration in the atmosphere is largely controlled by temperature, making it a feedback rather than a primary driver of climate change.

The natural greenhouse effect is essential for life on Earth, maintaining a habitable average temperature. Without it, the planet would be considerably colder. However, human activities, primarily the burning of fossil fuels, deforestation, and industrial processes, have significantly increased the concentration of certain greenhouse gases, particularly CO2 and methane, in the atmosphere.

This anthropogenic increase in greenhouse gas concentrations is leading to an enhanced greenhouse effect, causing global warming and climate change. The scientific consensus is that this warming trend poses significant risks to ecosystems, human societies, and the global economy. Understanding the role of "üvegházhatású" gases is crucial for addressing these challenges.
