The taiga is characterized by a cold, harsh climate, low rate of precipitation (snow and rain), and short growing season. Long, severe winters last up to 6 months, with average temperatures below freezing. Summers are short, lasting maybe 50 to 100 days without frost.
The taiga is very, very cold in the winter. Temperatures vary widely. For example, Verkhoyansk, Russia has recorded extremes of –67°C to 32°C (–90°F to 90°F). When the warmer temperatures of summer come, ice and snowmelt. The hours of daylight are much longer during the summer.
Climate change puts taigas in danger in different ways. The warming climate contributes to a partial thawing of the permafrost. Since this water has no place to drain, more area of the taiga is taken over by muskegs. Few trees take root.
