The bigger picture

One climate system.
Different signals.

The atmosphere, oceans and ice are connected through the Earth’s energy balance. Greenhouse gases influence how energy leaves the planet; warming affects ocean temperatures, stored heat, sea ice and sea level.

No single reading captures that whole system. These indicators describe different processes, regions and timescales. Taken together, they help place individual measurements in a broader scientific context.

Indicators & original sources

What the measurements tell us

Each dataset has its own definition, coverage and reference period. The original source is the place to find its methods, uncertainty and revision history.

世界平均気温偏差

Temperature difference

An anomaly is a difference from a reference-period average, not the Earth’s absolute temperature. NASA GISTEMP uses a 1951–1980 baseline; this dashboard separately labels its estimated conversion to an 1850–1900 reference.

NASA GISTEMP v4

大気中CO₂

Parts per million · ppm

Carbon dioxide concentration describes the proportion of CO₂ in the atmosphere. Seasonal changes sit alongside the longer-term trend; concentrations are not the same quantity as annual emissions.

NOAA Global Monitoring Laboratory

世界平均海面水温

Surface temperature

This indicator tracks the ocean surface rather than the whole ocean. Its departure from the stated 1982–2011 mean is distinct from the pre-industrial reference used for global temperature.

Climate Reanalyzer · NOAA OISST v2.1

北極海氷面積

Million square kilometres · M km²

Extent counts ocean areas with at least 15% sea ice concentration. It changes strongly with the seasons and is not a measurement of ice thickness, volume or land ice.

NSIDC Sea Ice Index

世界平均海面水位

Millimetres · mm

Satellite observations track changes in the average height of the ocean relative to a reference. Thermal expansion and added water from land ice contribute; local coastal sea level can differ from the global mean.

Heat content measures stored energy, not temperature alone. This series covers the upper 2,000 metres of the ocean; it provides a different perspective from measurements of the sea surface.

Context & limitations

A snapshot, not a forecast

Different publication schedules

Some series update daily; others are monthly, quarterly or less frequent. The snapshot time records retrieval, while each indicator’s date identifies its observation period. Refreshing does not create a new observation.

Reference periods matter

Anomalies depend on the baseline beside each value. Comparisons with different baselines are not interchangeable. A single monthly temperature anomaly does not establish long-term exceedance of a Paris Agreement temperature goal.

Global is not local

Global averages do not describe the conditions at a particular street, farm or coast. Short-term variability, regional differences and dataset revisions remain important; consult the source methods before drawing conclusions.
