how is climate change affecting the arctic region?

Melting ice speeds up climate change. Global warming is causing Arctic ice to melt – ice reflects sunlight, while water absorbs it. When the Arctic ice melts, the oceans around it absorb more sunlight and heat up, making the world warmer as a result.

Climate change is the shift or abnormal change in climate patterns. As the planet warms quickly, mostly due to human activity, climate patterns in regions around the world will fluctuate. Ecosystems and biodiversity will be forced to fluctuate along with the regional climate, and that could harm many species.

The Arctic, Africa, small islands and Asian megadeltas are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.

Temperature-related changes include longer growing season, more heatwaves and fewer cold spells, thawing permafrost, earlier river ice break-up, earlier spring runoff, and earlier budding of trees. Meteorological changes include an increase in precipitation and more snowfall in northwest Arctic.

Climate is an important environmental influence on ecosystems. Changing climate affects ecosystems in a variety of ways. For instance, warming may force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival.

"Climate change is by far the worst threat to Arctic biodiversity. Temperatures are expected to increase more in the Arctic compared to the global average, resulting in severe disruptions to Arctic biodiversity some of which are already visible," warns Meltofte.

Climate change is not only an environmental phenomenon, its negative impacts have social and economic consequences, too. For its part, air pollution is the presence, in the air, of substances or particles that imply danger, damage or disturbance for humans, flora or fauna.

The Greenland and Antarctic ice sheets also influence weather and climate. Large high-altitude plateaus on the ice caps alter storm tracks and create cold downslope winds close to the ice surface. In addition, the layers of ice blanketing Greenland and Antarctica contain a unique record of Earth's climate history.

Climate change. A warmer climate could radically change tundra landscapes and what species are able to live in them. Warming creates potential feedback loops that encourage further destabilization of tundra ecosystems.

Challenges affecting polar bears The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.

These are the facts: Melting ice speeds up climate change. Global warming is causing Arctic ice to melt – ice reflects sunlight, while water absorbs it. When the Arctic ice melts, the oceans around it absorb more sunlight and heat up, making the world warmer as a result.

The climate of Alaska is determined by average temperatures and precipitation received statewide over many years. ... The climate in the extreme north of Alaska is an Arctic climate (Köppen ET) with long, cold winters, and cool summers where snow is possible year-round.

The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s. ... The melting of Greenland's ice sheet is linked to polar amplification.

Changing climate affects ecosystems in a variety of ways. For instance, warming may force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. ... For instance, climate change may exacerbate the stress that land development places on fragile coastal areas.

Warming climate contributes to a partial thawing of the permafrost. Since this water has no place to drain, more area of the taiga is taken over by muskegs. Few trees take root. Warming temperature also changes animal habitats.

Climate change increases water and air pollution which can cause and aggravate chronic respiratory disease, such as asthma. Increased temperatures due to climate change lead to increased ground-level ozone, which cause airway inflammation and damages lung tissue.

Arctic shrub growth in the tundra is one of the most significant examples on Earth of the effect that climate change is having on ecosystems. Taller shrubs prevent snow from reflecting heat from the sun back into space, warming the Earth's surface. They can also influence soil temperatures and thaw permafrost.
