What Is Global Warming Doing To Antarctica

Global warming has been the ongoing topic of debate for decades, and its effects on Antarctica have been at the forefront of this conversation. Throughout history, dramatic changes have taken place due to global warming, in both the physical and biological characteristics of the icy continent. The impact is being felt both near and far, as the effects of global warming have a ripple effect that reaches beyond the declines in wildlife populations and affects the entire planet.

One of the biggest changes to the Antarctic ecosystem are the rising sea levels. As the ice sheets and glaciers in the Antarctic melt, sea levels have risen by 2.6mm per year since 2000. This rise in sea levels is not only impacting coastal cities around the world, such as Miami, but it has also altered the entire coastline of Antarctica and the islands that surround it. As a result, the delicate ecosystems in these areas are facing serious disruption.

Notably, the impact of global warming is being seen in the mass amounts of blooming algae that are now appearing in areas of the continent that were traditionally icy and barren. These blooms of algae are forming a vast underwater Garden of Eden, providing a variety of vital resources for the species that inhabit the area. Unfortunately, for some species, the blooms provide too great an influx of nutrients and have triggered an explosion of harmful bacteria. This has made life difficult for many species, including minke whales and Adelie Penguins, which feed off of the tiny creatures living in these areas.

The melting of glacial ice also has a dramatic and direct effect on many species of animals that rely on the ice for nesting and breeding grounds. The Emperor Penguins, for example, traditionally lay their eggs on top of the snow-covered ice. As the ice melts, this is becoming increasingly difficult, and many of these eggs are washing away. In addition, as the snow melts, the emperor penguin’s main food source, krill,are beginning to migrate further north, away from their traditional feeding grounds.

Global warming has both a direct and indirect impact on Antarctica’s wildlife populations, and the rapid and dramatic shifts in climate are making it difficult for species to adapt. For some species, the destruction of their environment is making it impossible to survive. Meanwhile, the loss of native populations due to rising temperatures is allowing new species, such as invasive plants and marine organisms, to move in, further disrupting the local eco-system.

The changes caused by global warming are visible, from the effects on sea levels to the changing of the landscapes, and their impact will continue to be felt for years to come. As the global community comes together to tackle this issue, it is essential that the status of Antarctica’s wildlife and the impact of climate change is taken into account and addressed with urgency. Collaboration between countries, industries, and organizations is key in order to ensure that we can protect the fragile polar environment for future generations.
