Describe the taiga climate.

The taiga biome is also known as the boreal, snow, or coniferous forest. It covers subarctic lands, extending across most of upper North America and Eurasia. The tundra borders it to the north while the steppe is to the south. It is characterized by coniferous vegetation such as the evergreen spruce, pine, fir, and the larch. These conifers are adapted to the cold climate of the taiga through their conical shapes, needle leaves, and evergreen nature. The needle leaves reduce the surface area through which the trees lose water via transpiration. Since these trees are always green, they do not shed their leaves during winter; hence they do not use up energy to regrow these leaves in spring. Furthermore, the dark color of the needle leaves help the trees to take up energy from the sun for photosynthesis. The conical shape helps the snow to slide off the branches of the trees.
The climate of the taiga is characterized by cold arctic air and low temperatures. During winter, the biome receives little radiation from the sun because it is tilted away from the sun. Winters last for about six to seven months, with lows of about –65 degrees Fahrenheit and highs of about 30 degrees Fahrenheit. The average taiga temperature in winter is, however, higher than that of the tundra biome. Summers are short, hot rainy seasons, with lows of about 30 degrees Fahrenheit and highs of about 70 degrees Fahrenheit. Its average yearly precipitation is between 15 and 20 inches.
