How is the Arctic changing?
The Arctic is more impacted by global warming than any other place in the world. And with the world growing warmer, Arctic ice is melting even faster, threatening their safety and way of life. Already in the past 30 years, we’ve seen areas of Arctic sea ice melt that are larger than Norway, Sweden and Denmark combined.
Why is climate change happening in the Arctic?
The average temperature of the Arctic has increased 2.3°C since the 1970s. Ice dependent species such as narwhals, polar bears, and walruses are at increasing risk with shrinking sea ice cover. As the Arctic loses snow and ice, bare rock and water absorb more and more of the sun’s energy, making it even warmer.
Is the Arctic environment changing?
The global climate is changing. The Arctic is warming at a rate almost twice the global average and reductions in Arctic sea-ice and permafrost and changes in weather are increasingly visible. Arctic marine mammals are uniquely adapted to life in the Arctic.
What is causing the Arctic to melt?
Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.
What is causing climate change?
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.
What is the new Arctic?
The UK’s Natural Environment Research Centre supported Arctic research centre is based at Ny-Alesund, on the island of Spitsbergen in Svalbard. Led by the station commander Nick Cox, scientists are undertaking ongoing research into the cryosphere to better understand its features and how it is changing.
What are the problems in the Arctic?
Three main environmental issues are apparent in the Arctic: climate change, changes in biodiversity and the use of toxic chemicals.
How is climate change affecting the north?
There have already been significant environmental changes in the North as a result of increasing temperatures. These include decreased ice thickness, melting of permafrost, coastal erosion, rising sea levels, landslides, and altered distribution and migration of wildlife.
Why is climate change happening and what are the causes?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
