ohutuskliima

Ohutuskliima, also known as the greenhouse effect, is a natural process that warms the Earth's surface. It occurs when certain gases in the atmosphere, known as greenhouse gases, trap heat from the sun. These gases include carbon dioxide, methane, nitrous oxide, and water vapor. They allow sunlight to pass through the atmosphere and reach the Earth's surface, where it is absorbed and re-emitted as heat. This heat is then trapped by the greenhouse gases, warming the planet.

The greenhouse effect is essential for life on Earth, as it maintains the planet's average temperature at around 15 degrees Celsius. Without it, the Earth would be too cold to support most forms of life. However, human activities, such as burning fossil fuels and deforestation, have increased the concentration of greenhouse gases in the atmosphere. This enhanced greenhouse effect, often referred to as global warming, is causing the Earth's temperature to rise.

The consequences of global warming include more frequent and severe heatwaves, changes in precipitation patterns, rising sea levels, and increased frequency of extreme weather events. These changes can have significant impacts on ecosystems, human health, and economies. To mitigate these effects, efforts are being made to reduce greenhouse gas emissions and transition to renewable energy sources.
