Climate change has profoundly affected brown bears: here’s what happened to them

Current climate change affects all of Earth’s inhabitants, including the famous brown bears: here’s what they risk

Over millions of years, the Earth has experienced climate change many times, and in fact many species have evolved or become extinct due to the climate. This means that current climate change, which affects almost all sectors, This is nothing new on the planet. So why are all scientists worried? In fact, the concern stems from the speed with which climate change is occurring.

For the first time in history, we are actually witnessing a sudden acceleration of climate events, undoubtedly caused by human activity. Recently, some scientists have argued that the effects of climate change also threaten the health of brown bears.

Climate change threatens brown bears

Scientists are very concerned about the future of brown bears, especially those in Siberia. It is no coincidence that the Siberian region was recently hit by an unusual heat wave, the effects of which have particularly disconcerted bears. Even more surprising are the high temperatures recorded in November in Siberia: in this period In fact, the temperature should be between -26 and -19 degrees Celsius. Therefore, the extremely cold climate forces bears to hibernate, i.e. hibernate, in order to survive the long winter.

But climate change has revolutionized everything this year: many animals were unable to hibernate due to the abnormal heat. The news that surprised the scientific world was revealed by the Wildlife Department, which announced that the most affected animals were male brown bears. this is the last They looked so confused and astonished. Normally, all species that hibernate try to accumulate a large amount of food, especially fat. The vast reserves are clearly intended to allow the animal to survive during the winter months.

And not only that: shortly before the start of semi-hibernation, many species begin to look for a place to sleep for the whole winter. Unfortunately, in recent months, researchers have observed completely disoriented brown bears, for the first time They do not feel the need to hibernate. In fact, a temperature above zero was recorded on November 20, which is exactly what was expected -26 or -19 degrees Celsius. Fortunately, after a few weeks, the extreme cold finally arrived, bringing temperatures back to the seasonal average.
