Planet trends

Some signals belong to the whole planet rather than any one country. These are the big three: the ocean storing the heat, the sea rising, and the ice sheets losing mass.

19402025

The world in stripes: every year since 1940, blue cooler than the 1991-2020 average, red hotter.

Global sea level

66.0 mm vs 1993-2008 average · 2020
-1000190019502000low 1882

The global average sea surface height. It rises as warming water expands and land ice melts into the ocean. Church & White / UHSLC via Our World in Data

Ocean heat content (top 2000m)

32.5 10²² joules · 2025
0201960198020002020

Over 90% of the extra heat trapped by greenhouse gases ends up in the ocean. This is the planet's clearest warming signal. NOAA NCEI via Our World in Data

Ice sheet mass change · Antarctica

-2,539 Gt vs 2002 · 2020
-2k-1k02005201020152020

How much ice Greenland and Antarctica have lost since 2002, measured from space by tracking tiny changes in Earth's gravity. NASA GRACE via Our World in Data

Ice sheet mass change · Greenland

-4,843 Gt vs 2002 · 2020

How much ice Greenland and Antarctica have lost since 2002, measured from space by tracking tiny changes in Earth's gravity. NASA GRACE via Our World in Data

The world in aggregate

Every country on the map, summed or averaged into one line per metric. This is the whole story in a handful of curves.

Temperature anomaly · World

0.59 °C vs 1991-2020 · 2025
-0.500.519401960198020002020high 2024low 1956

How much warmer or cooler a country's year was compared with its 1991-2020 average. Watch the map turn red as you move the slider towards today. Copernicus Climate Change Service (ERA5) via Our World in Data

Air pollution (PM2.5) · World

29.9 µg/m³ annual mean · 2024
010203020002005201020152020high 2015low 1999

Average exposure to fine particles small enough to enter the bloodstream. The WHO guideline is 5 µg/m³. World Bank / van Donkelaar et al. via Our World in Data

Meat supply per person · World

45.1 kg/person/year · 2023
02040198020002020

Meat available for consumption per person. Livestock drives around 15% of global emissions and most deforestation. FAO via Our World in Data

The sea to 2100

Global sea level, observed and projected under three scenarios

050019001950200020502100Low · SSP1-2.6Middle · SSP2-4.5High · SSP5-8.5low 1882

Solid line: the observed global average. Dashed lines: median projections from IPCC AR6 WGI Table 9.9 (medium confidence processes), aligned to the observed record's baseline. Even the lowest pathway commits the sea to further rise; the scenarios only truly part ways after mid-century.
