Global Temperature

The global mean temperature for Jan 26th 2026:

2.68°C 36.82° F

November 15th 2025, earth - sun distance 148 million km, sun latitude 18°S. Jan 26th 2026, earth-sun is in the same position. Except earth is 1.7°C colder.

On November 15th northern hemisphere snow was 28 million km2, sea ice extent 8.5 million km2 (36.5 million km2). In the southern hemisphere Antarctic continent is 14.2 million km2 and sea ice 14.93 million km2 (29.1 million km2) . On January 26th northern hemisphere snow was 45 million km2, sea ice was 12.8 million km2 (57.8 million km2). In the southern hemisphere Antarctic continent is 14.2 million km2 and sea ice 3.69 million km2 (17.89 million km2). So snow and ice is greater in January 26th vs November 15th despite same solar input.

Global oceans temperature is also less on January 26th 2026 than November 15th 2025.

November 15th 14.17°C (sea ice 23 million km)

January 26th 14.09°C (sea ice 16.49 million km)

November 15th was 0.7°C above normal and January 26th was 0.7°C below normal (now corrected from 0.56°C).

The suns energy 1406w-m2 (proportional to 124°C).

Earth's outgoing is over half being reflected to space.

So outgoing heat is proportional to 69°C as snow and ice is reflecting more heat.

At 2.68°C that's proportional to 327.49w-m2 of thermal insulation.

1/4 of the total 1309.9w-m2, proportional to 116.7°C.

But as earth is below normal more heat is escaping to space.

61.9°C of the 116.7°C is outgoing heat to space.

Earth's thermal heat at 54.8°C part of 116.7°C from the sun, the tropics maintains a 25°C temperature profile while transported heat 54.8°C reaches the edges of the hemisphere's outer zones (-22.5°C) 2.7°C 40°N, (-22.3°C) 2.7°C 59°S.

Reason large continents cool down and experience more land snow.

Both poles therefore cool to -24°C north and -23°C south.

The average emitted heat is less than the thermal heat 327.39w-m2 of the atmosphere at 324.79w-m2, this due to more snow and ice causing the below normal status.

The 54.8°C is proportional to 655w-m2, some of this is excess heat is outgoing heat.

80.51°C (40°N to 50°S) - 11.5°C NH, -14.2°C SH.

As the tropics has so much heat, annual temperature swings are very small.

Of this 80.5°C, 25.7°C is the internal heat, 54.8°C is the excess.

The average excess heat over 9 10th latitudes is 98.55w-m2 per 10th latitude (40°N to 50°S) of which 25.7w-m2 is internal.

231.51w-m2 plus outgoing 423.46w-m2 equals 655w-m2.

Of the 231.51w-m2 195.51w-m2 comes from kinetic heat of molecules, 36 w-m2 comes from latent heat (mostly absorbed UV heat from the ground).

Outgoing longwave 247.6w-m2 and 140.92w-m2 shortwave.
