CASE 1. Vast continental territory of Siberia (approximately 10 mln km2), which has weak technogenic impact. Some regions are free of such an impact at all…

CASE 2. Statistical analysis shows that accelerated warming is observed in Siberia in the last few decades (up to 0.5 C/10 years)…

CASE 3. The wavelet analysis of time series

of the surface temperature shows that clearly

pronounced (statistically significant)

periodicities are present in the range from 5

to 30 years …

CASE 4. It follows from analysis of 2D

climate phase pattern in Tomsk that climate

aridity significantly increased in recent five

years …

CASE 5. Comparison of evolution

trajectories for surface temperature in two

Siberian cities (Omsk and Krasnoyarsk)

revealed (quantitatively) influence of an

anthropogenic event on climatic changes

observed…

CASE 6. Investigations of observed environmental and climate changes in Siberia are carried out by qualified researchers…
