The decline of Canada’s caribou

Caribou is a species of deer with a circumpolar distribution, native to the Arctic, sub-Arctic, tundra, boreal, and mountainous regions of northern Europe, Siberia, and North America. Caribou, known as reindeer in Europe, are a majestic species of deer that are iconic in the northern regions of Canada. They are well-adapted to cold environments and can be found across various habitats, including boreal forests, tundra, and mountainous regions.

The Future of U.S. Weather: A Look at 2050

As we approach 2050, the climate of the United States is set to undergo substantial changes. Rising temperatures will redefine what we consider typical weather patterns, affecting annual, summer, and winter temperatures nationwide. This post explores the projected climate shifts, supported by insightful maps that illustrate these changes. Rising Temperatures Across the Board By 2050, every city in the U.S. will experience warmer winters and summers. These increases are not just minor fluctuations but significant changes that will reshape the climate landscape. Overall, annual temperatures are expected to rise across the country. Summer highs will see the most dramatic increases, with many regions experiencing hotter and longer summers. Winter temperatures will also climb, leading to milder winters in areas that currently experience harsh cold. This map, created by Vox highlights the projected changes in both summer and winter temperatures across the U.S. by 2050. Noticeable increases
