Klímamutatókat, or climate indicators, are measurable pieces of information that help us understand the Earth's climate and how it is changing. These indicators provide a snapshot of the climate system at a particular time or track changes over time. They are crucial for scientific research, policy-making, and public awareness regarding climate change.

Commonly used climate indicators include global average surface temperature, which shows the overall warming trend of the planet. Changes in sea level are another important indicator, reflecting the expansion of warming ocean water and the melting of glaciers and ice sheets. Precipitation patterns, including both the amount and intensity of rainfall and snowfall, are also monitored to understand shifts in water availability and extreme weather events.

Atmospheric concentrations of greenhouse gases, such as carbon dioxide and methane, are directly linked to human activities and are a primary driver of climate change. Ocean heat content, indicating the amount of thermal energy stored in the oceans, is also a significant indicator, as oceans absorb a vast majority of the excess heat. Furthermore, the extent of Arctic sea ice and the frequency and intensity of extreme weather events like heatwaves, droughts, and floods serve as vital indicators of a changing climate. Scientists use data from a wide range of sources, including satellites, weather stations, and ocean buoys, to collect and analyze these indicators, providing a comprehensive picture of our planet's evolving climate.
