Effects Of Climate Change On The Arctic

Effects Of Climate Change On The Arctic – The Arctic is a remote place in the northernmost part of the Earth with extreme environmental conditions. Many people may imagine large icebergs, vast expanses of snow, and animals with stunning white fur when they picture this polar region.

But some other images that are increasingly associated with the Arctic are these magnificent animals stranded on lonely icebergs or exhausted from lack of food. The above photo of a starving polar bear was taken by German photographer and conservationist Kerstin Langenberger and has been shared more than 51,000 times on Facebook.

While Langenberger admits she can’t show a direct link between climate change and the bear she photographed, she doesn’t rule out that climate change may have something to do with it.

“Climate change is indisputable,” she said. “It’s happening and we have to do something about it.” And this photo, I can say to all of you: Look at it.”

To fully understand the state of the Arctic, it is necessary to know what climate change is and how climate change affects different parts of the Arctic and its wildlife. Several movements are also trying to help with conservation efforts in the Arctic, so there are several ways to get involved.

NASA defines climate change as “a long-term change in the average weather patterns that have defined Earth’s local, regional, and global climate.” When climate change is discussed as an urgent issue facing the world, it is because these changes in weather patterns cause many different problems for life on Earth.

Climate change refers to general weather changes observed globally. On the other hand, global warming is a specific phenomenon of an increase in average surface temperatures. Climate change is the umbrella term under which global warming fits.

How Climate Change Is Threatening Polar Bear Populations

No area of ​​the planet will escape the consequences of climate change, because the Earth has only one climate system. This system is a complex global framework of several components, including the atmosphere, hydrosphere, cryosphere, land surface, and biosphere. Therefore, climate change will inevitably affect all world ecosystems.

The Arctic is experiencing many changes due to global warming. While average temperatures are rising around the world, temperatures in the Arctic are reportedly rising three times faster than the global average. We can clearly see these changes in its oceanic and polar ice caps.

Every ecosystem is made up of an intricate and delicate chain of different species that interact and maintain balance. When that balance is disturbed in some way, either by humans or organic problems like disease, all of these species can experience dramatic changes.

For example, while the Arctic Ocean is usually covered in ice for most of the year, that ice is beginning to melt due to increased global temperatures. Because many species rely on sea ice cover for hunting grounds or to maintain certain living conditions, the ecosystem is thrown into turmoil as sea ice continues to disappear.

Arctic Global Warming So Rapid That Computer Measuring It Rejected The Results

The primary problem now facing the polar ice caps is unprecedented levels of melting due to global warming. The World Wildlife Fund (WWF) reports, “We are losing Arctic sea ice at a rate of nearly 13% per decade” and that we have the potential to see an ice-free Arctic by the summer of 2040.

Another major problem is that global sea levels will rise as these ice caps melt into the ocean, affecting coastal communities, island states and other environments. The impact of melting ice caps is deep and wide, from impacts on wildlife and global temperatures to food crops and weather patterns.

Arctic wildlife faces many challenges due to environmental impacts caused by climate change. For example, global warming poses risks to food access, habitat compatibility, and potentially encouraging invasive species and diseases, to name a few.

It can be difficult to visualize the threats posed by climate change without knowledge of the animals that are actually at risk. As the Arctic ecosystem is thrown out by climate change, several species face imminent threats. A few examples include:

Arctic Ice Melt Is Changing Ocean Currents

Other species at risk from Arctic climate change include narwhals, arctic foxes, orcas, lemmings, beluga whales, red knots (wading birds) and muskrats. Threats to these animals have made many of them endangered species.

Preventing climate change in the Arctic means preventing climate change worldwide. Climate change is a problem facing the whole world and must be solved together with global coordination. So what can be done to stop global warming?

The Union of Concerned Scientists is an organization that analyzes the threats of climate change and proposes solutions to reduce and deter them. The most significant causes of climate change are large carbon emissions and an excessive amount of carbon dioxide and greenhouse gases in the atmosphere. These are issues that continue to be industry sources and must be addressed by laws and regulations.

The UN regularly convenes meetings between nations to develop effective policy goals related to slowing climate change. The 2019 Climate Action Summit was one recent meeting where these issues came into play, with the UN presenting its proposed initiatives in a detailed guide.

The 26th UN Conference of Parties on Climate Change (COP26) was held from October 31 to November 12, 2021. This conference brought together many members to discuss climate goals for the world. One of the results of this event was the Climate Pact in Glasgow, where the gathered parties undertook to follow specific actions to keep the global average temperature rise below 1.5 degrees Celsius.

In addition to the global initiatives adopted by COP26 members, the UN also offered guidance on how individuals can address climate change. In addition to reducing the carbon footprint, it is also important to reach out to local representatives regarding the adoption of policies that focus on climate change action and sustainable energy.

Climate change will undoubtedly affect every living thing around the world. Understanding what climate change really is and being aware of the impact on the environment and animals is the first step towards change.

To combat climate change in any particular region, we must confront the issue of climate change worldwide.

Facts About Polar Bears & Arctic Conservation For International Polar Bear Day

The early breakup of sea ice and a longer period of open water hampered their search for food, mainly seals. Not enough ice leads to less time to hunt, less time to eat – and fewer bears.

The majestic bear’s decline in size was determined by field workers who recorded its weight and length in the western Hudson Bay region and then compared it with measurements from 1980.

Female polar bears now weigh an average of 230 kilograms or 507 pounds (once weighed 295 kg or 650 pounds) and stand 220 centimeters, or nearly 7-foot-3 (once 225 cm). Their skull is also reduced. Weight loss can adversely affect the birth of healthy pups.

Some populations, such as those in the western Hudson Bay and southern Beaufort Sea, are already feeling the effects of a warming climate.

These conclusions are based on decades of research into their population ecology. Other populations may be similarly affected, but “we don’t have adequate long-term data to definitively address this,” said Ian Stirling, an associate professor of biological sciences at the University of Alberta.

“However, the trends illustrated in the western Hudson Bay and southern Beaufort Sea give us a clear indication of what is happening across the circumpolar Arctic,” added Prof. Stirling. “In 100 to 150 years, without an end to global warming, polar bears will have a very difficult time.”

There are currently an estimated 20,000 to 25,000 polar bears worldwide, of which 15,500 roam Arctic Canada in search of food.

“Climate change is certainly a problem for a northern animal whose habitat includes sea ice,” said Justina Ray, senior scientist at the Wildlife Conservation Society and co-chair of the committee.
