Introduction

The article discusses the effects of global warming on the Arctic, including its ecological consequences and how it affects people in northern regions.

Melting Sea Ice & Glaciers

Global warming is causing dramatic changes to the Arctic region—melting sea ice, glaciers, and permafrost—and raising temperatures. This has caused shifts in species ranges as animals migrate further north or become extinct due to habitat loss. It has also disrupted traditional lifestyles of Indigenous peoples who rely on hunting and fishing for subsistence.

Ecosystem Consequences

The melting sea ice has had serious ecological consequences for wildlife such as walruses and polar bears which depend on it for survival. The increase in open water has also resulted in more frequent storms with stronger winds which can cause erosion of coastal areas where many species live. Furthermore, warmer waters are leading to an increase in harmful algal blooms which are toxic to both marine life and humans.

Impact On People

These changes have impacted human populations living in northern regions through food insecurity due to reduced access to traditional sources of sustenance such as seafood, increased costs associated with shipping goods into remote communities, economic disruption from decreased tourism opportunities related to receding glaciers, reduced access to clean drinking water due to thawing permafrost that can lead to contamination from pollutants stored underground, and a loss of cultural identity caused by disruption of traditional ways of life that were intertwined with their environment.

Conclusion

Overall, global warming is having profound impacts on the Arctic ecosystem as well as on the lives of those living there both now and into the future unless action is taken to reduce greenhouse gas emissions leading up to this point.
