A study carried out by University of Alaska, Fairbanks, has found that water bodies in Alaska, have been shrinking dramatically for the last 50 years, making this state a lot warmer and drier. The findings of this study, published in the Journal of Geophysical Research, says that water bodies in Alaska have witnessed tremendous change in the last few decades, with thousands of ponds shrinking in size and many others drying out. The water table in all ponds in sub-arctic Alaska fell by 4 to 31% during this period, with most of the change occurring since the 1970’s.

 

Birds like duck, geese and swan (waterfowls), breed in the water bodies in Alaska and the reduction in water table could have a significant on the population of these birds. Scientists say that Alaska is witnessing longer summers, melting permafrost and increasing water loss through evaporation and transpiration.
