"The Impact of One Degree of Warming: A Closer Look"

A study led by Northern Arizona University ecologist Andrew Richardson found that even slight increases in temperature in boreal forests can lead to a significant reduction in snowpack, resulting in increased plant stress, mortality, and potential fire risk. The research, published in the Journal of Geophysical Research: Biogeosciences, used long-term warming experimental results to show that less snowpack leads to warmer air temperatures and more snowmelt, with implications for ecosystem functioning and climate modeling. The findings suggest that transitioning to low- or no-snow winters could have major negative impacts on northern ecosystems.

The Mighty Mosquitoes of Alaska: A Pound for Pound Powerhouse.

Alaska is home to at least 27 species of mosquitoes, with the "snow mosquito" Culiseta alaskaeensis being a thumbnail-sized insect that hibernates until spring. Female mosquitoes follow trails of carbon dioxide and body odor to draw a blood meal, which helps make their eggs viable. Derek Sikes, curator of insects at the University of Alaska Museum of the North, once calculated that about 17 trillion mosquitoes hover over Alaska each summer, with a combined weight of 96 million pounds.
