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 …
Two-dimensional phase pattern of states of regional natural and climate system (Tomsk)
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…
