Kotuy River. Taymyrskiy Region, Siberia
The climate at the location is near the limit of the coldest temperatures larch trees can tolerate. The smaller of the two trees in the foreground is many centuries older than the bigger tree. |
Siberia evokes images of a frigid land of extreme cold. These days, to ecosystem scientists, Siberia is becoming synonymous with heat wave. Northern Siberia in particular is a climatic hot spot—an area that is warming faster than the rest of the planet. In the past 30 years, average temperatures across the region have risen 1-3 degrees Celsius (3-5 degrees Fahrenheit), while the worldwide average increase in that time is about 0.6 degrees C (1 degree F). Starting July 10, 2008, Dr. Ranson and Dr. Kharuk will lead a team of American and Russian scientists to study an extremely remote and harsh section of northernmost central Siberia.
