hmérsékletemelkedése

Hmérsékletemelkedése, often translated as global warming or climate change, refers to the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects of the human-produced warming on our planet.

The scientific consensus is that the Earth's climate system is unequivocally warming, and that it is extremely likely (95% probability) that human influence has been the dominant cause of the observed warming since the mid-20th century. The most common greenhouse gas is carbon dioxide, but others include methane, nitrous oxide, and fluorinated gases.

The consequences of hmérsékletemelkedése are far-reaching and include rising sea levels, more frequent and intense heatwaves, changes in precipitation patterns, and impacts on ecosystems and biodiversity. Addressing hmérsékletemelkedése involves both mitigation efforts, such as reducing greenhouse gas emissions, and adaptation strategies to cope with the inevitable changes. International agreements and national policies are in place to try and combat this global phenomenon.
