Summary


Data by Nasa about the year «mean temperature» [1], black curve, and the speculations around.

The picture is an attempt to interpret the evidence of the Global warming as a result of human activity.

Description

The abscissa is time y measured in years.

The ordinate is «mean temperature» z in the Celsius scale.

Black curve shows the data by NASA.

Red curve shows the quadratic fit:

z= 0.50957748 + t*(0.01669969 + t*0.00009021 )

where t=y-2000

The sum of squares of deviations for this approximation is 2.01 (Celsius2)


Green curve shows the pessimistic estimate; it is parabola that lies above all the values available:

z= 0.87 + t*(0.0138 + t*0.000051 )

The blue curve represents the primitive model, in which the warming is interpreted as a result of big wars that may cause covering of snow with ache and aged the main temperature: 

z= -.265 - .002*(y-1880)
+ .107*(1.+tanh(.2*(y-1914.)))
+ .107*(1.+tanh(.2*(y-1939.)))
+ .107*(1.+tanh(.2*(y-1979.)))
+ .107*(1.+tanh(.2*(y-1994.)))
+ .107*(1.+tanh(.2*(y-1999.)))
+ .107*(1.+tanh(.2*(y-2008.)))
+ .107*(1.+tanh(.2*(y-2014.)))
+ .107*(1.+tanh(.2*(y-2022.)))

The following wars are taken into account:

World War I, 1914
World War II, 1939
Soviet invasion into Afghanistan, 1979
First Chechen war, 1994
Second Chechen war, 1999
Russian invasion into Georgia, 2008
Annexation of Crimea and seizing of Ordlo (Hybrid war), 2014
Full-scale Russia-Ukraine war (spetsoperation), 2022

In the primitive model, the contributions of these wars are assumed to be similar.

The sum of squares of deviations for this approximation is 1.73 (Celsius2);
it is 14% better than that the quadratic approximation.

The blue curve corresponds to hypothesis that the Putin world war stops approximately in year 2025; then without big wars, the mean temperature decreases.

In such a way, the model with blue curve is not so realistic.
