lämpötilanmuutos

Lämpötilanmuutos refers to the change in temperature over time. This can encompass a wide range of phenomena, from the daily fluctuations of weather to long-term climatic shifts. On a local scale, temperature changes are influenced by factors such as solar radiation, atmospheric pressure, wind, and precipitation. For instance, the transition from day to night or the passage of a weather front can cause noticeable temperature variations.

On a global scale, the term "lämpötilanmuutos" often relates to climate change, specifically the observed increase in the Earth's average temperature. This long-term trend is primarily attributed to the increased concentration of greenhouse gases in the atmosphere, largely due to human activities such as burning fossil fuels and deforestation. These gases trap heat, leading to a gradual warming of the planet.

The consequences of lämpötilanmuutos can be far-reaching and include rising sea levels, more frequent and intense heatwaves, altered precipitation patterns, and impacts on ecosystems and biodiversity. Understanding and monitoring temperature changes are crucial for scientific research, weather forecasting, and for developing strategies to address climate change. Various instruments, like thermometers and satellites, are used to measure and track temperature variations across different regions and time scales. The study of past temperature changes, known as paleoclimatology, utilizes indirect evidence from sources like ice cores and tree rings to reconstruct historical climate conditions.
