Klimatváltozás

Klimatváltozás refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. However, since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil, and gas.

The burning of fossil fuels generates greenhouse gas emissions. These emissions act like a blanket wrapped around the Earth, trapping the sun's heat and raising temperatures. Examples of greenhouse gas emissions that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. This process, known as greenhouse effect, can be used to Moderate the Earth's temperature and make it habitable. Without it, Earth would be too cold to support life.

The consequences of global warming include, but are not limited to, more intense droughts, water scarcity, severe fires, rising sea levels, flooding, melting polar ice, catastrophic storms, and declining biodiversity. The scientific consensus is that the Earth's climate system is unequivocally warming, and that it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. Addressing climate change involves both mitigation, reducing greenhouse gas emissions, and adaptation, adjusting to the current and future effects of climate change.
