Éghajlatváltozási

Éghajlatváltozási, or climate change, refers to long-term alterations in statistical distribution of weather patterns over multiple decades or longer. It encompasses changes in temperature, precipitation, wind patterns, and other aspects of the climate system. The primary cause of climate change is the increase in greenhouse gases, such as carbon dioxide and methane, which trap heat in the Earth's atmosphere and lead to global warming.

The scientific consensus is that climate change is primarily driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes. These activities release large amounts of greenhouse gases into the atmosphere, exacerbating the natural greenhouse effect and causing the planet to warm at an unprecedented rate.

The impacts of climate change are widespread and include rising global temperatures, melting glaciers and polar ice, sea-level rise, more frequent and severe weather events, and disruptions to ecosystems and biodiversity. These changes pose significant challenges to human societies, economies, and ecosystems, requiring urgent and substantial mitigation efforts to reduce greenhouse gas emissions and adapt to the impacts of climate change.

International efforts to address climate change are coordinated through the United Nations Framework Convention on Climate Change (UNFCCC), which aims to stabilize greenhouse gas concentrations in the atmosphere to prevent dangerous anthropogenic interference with the climate system. The Paris Agreement, adopted in 2015, is a landmark international treaty that sets global targets for reducing greenhouse gas emissions and promoting climate resilience.

In summary, climate change is a complex and pressing global challenge that requires collective action and commitment from individuals, communities, and nations to mitigate its impacts and build a sustainable future.
