kasvihuoneympä or greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. These greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, act like the glass of a greenhouse, trapping heat and preventing it from escaping into space. This trapped heat warms the Earth, making it habitable for life.

Without the natural greenhouse effect, the Earth's average temperature would be about -18 degrees Celsius (0 degrees Fahrenheit), making it too cold for most life forms to survive. However, human activities, particularly the burning of fossil fuels like coal, oil, and natural gas, have significantly increased the concentration of greenhouse gases in the atmosphere. This enhanced greenhouse effect leads to global warming and climate change.

The increase in greenhouse gases traps more heat, causing global temperatures to rise. This warming can lead to a variety of changes in the Earth's climate system, including more frequent and intense heatwaves, altered precipitation patterns, rising sea levels, and increased ocean acidity. Scientists are working to understand the complex interactions within the climate system and to develop strategies to mitigate the impacts of climate change.
