Eisbears in danger: Last expedition of a passionate scout

Eisbears in danger: Last expedition of a passionate scout

Hudson Bay, Kanada - On May 28, 2025, a two-part documentary is broadcast over polar bears in the north. The film tells the story of a year with these mighty predators, under the direction of Eisbär Scout Dennis Compayre. Dennis, who has a long love for polar bears, has been watching the Hudson Bay bears in Canada for decades and may be planning his last expedition to follow an polar bear family for a year. His goal is to examine the adaptation of the animals to the changes from global warming. This expedition trip takes place against the background of alarming environmental studies that indicate that the polar bears in Hudson Bay could die regionally in the 2030s should continue to increase global temperatures. This reports the website specensterben.de.

A new study published in the Journal Communications Earth & Environment analyzes the effects of a global increase in temperature above two degrees Celsius on the polar bear population in Hudson Bay. Researchers from North American and international institutions warn that this increase could have dramatic consequences for the bears and their food source, the ring seals. Every year in July, the backward -soaked sea ice is forcing the polar bears ashore, where they rely on their fat reserves to survive. Climate change has already led to a significant decrease in the number of ice -covered days in Hudson Bay, which impairs the basis of the ring seals that create their caves on the ice.

The threat from climate change

The Hudson Bay, a margin of ice creamy -covered by ice, is home to large ice bear populations (Ursus Maritimus). However, the change in the climate caused a decline in polar bear populations in the 1990s, especially in western Hudson Bay. Persistent moderate warming of 1.6 degrees Celsius could lead to the polar bears of the southern Hudson Bay may not be able to survive. When heating two degrees, it is expected that the ice -free periods in the region will last between 174 and 182 days. Most ecologists agree that polar bears would not survive a fasting period of more than 180 to 200 days, which underlines the need to combat climate change.

In order to minimize the devastating effects of climate change, measures such as reducing emissions and minimizing the CO2 footprint are urgently required. The knowledge of the study is not only important for the polar bears, but also apply to other endangered ecosystems, such as coral reefs in Florida and Australia. Another example of the devastating consequences of climate change is the extinction of the Bramble-Cay mosaic tail rat, the habitat of which was lost due to the rising sea level.

Denis Compayre's documentary about the polar bears and the results of the climate studies show the urgent need to sharpen the awareness of climate change and to work globally in order to ensure the survival of these majestic animals and many other species.
