A team of researchers has been studying native lake trout in lakes across Canada. They knew that climate change could change Canadian ecosystems drastically. To support the study, the scientists looked for data on lake geography, their physical characteristics, and even the fish communities living within them. Eventually, they assembled a dataset of almost twenty-two thousand Canadian lakes and could draw conclusions about how the lakes are impacted by climate change.

Ice cores are long cylinders of ice that are drilled from ice sheets and glaciers. Some ice does not melt, even in the summer, so the snow that falls on it buries snow from past years. That snow eventually turns into ice that has captured the chemicals that were in the air and on the snow when it formed, including pollutants. Ice cores can reveal atmospheric particles or aerosols (which are tiny invisible pieces of solids or liquids that float in the air and even in our atmosphere!) from thousands of years ago and tell us a lot about what the world used to be like.

Trees are important, both environmentally, creating oxygen, shelter, and food for the creatures in their environment, and economically, providing lumber for industry and construction. Assisted migration is being considered to help conserve some trees that are not able to spread their seeds fast or far enough to move to new environments as their old ones become uninhabitable for them due to climate change. Scientists have been researching cold adjustment in tree rings of migration-assisted trees to see how far we can move trees to other areas and have them thrive.

Many of the lakes in the Beaver Hills are wide, shallow, open waterbodies. Since the 19th century, the area has seen dramatic declines in water levels; in the 1860s, Beaver Hill Lake had dried to the point of bison being stuck in the mud of the lakebed. As settlers arrived the next sixty years saw significant changes in land-use and water-use in the region; forests were cleared, and agriculture expanded in the Beaver Hills. Most of the lakes in this area have experienced a decline in water year-after-year, and Beaver Hill Lake has nearly dried out three times in the last century.
