What did the Arctic climate Impact Assessment confirm?
ACIA (Arctic Climate Impact Assessment), approved by the eight Arctic countries, was called for by the Arctic Council and the International Arctic Science Committee. The assessment found that the Arctic is extremely vulnerable to observed and projected climate change and its impacts.
What climate factors are affecting the Arctic?
Factors Affecting Arctic Weather and Climate
- Latitude and Sunlight. The amount of sunlight hitting the Earth’s surface is affected by the tilt of the Earth and its atmosphere.
- Pressure. Example of a synoptic chart for 28 August 1980.
- Temperature.
- Geography.
- Wind.
- Humidity.
- Clouds.
- Precipitation.
What is impact assessment in climate change?
Climate change impact assessments seek to characterize, diagnose, and project risks or impacts of environmental change on people, communities, economic activities, infrastructure, ecosystems, or valued natural resources (1).
What is Arctic climate?
The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter. The Arctic consists of ocean that is largely surrounded by land.
Why is the Arctic vulnerable to climate change?
That the Arctic should be especially sensitive to climate change was recognized in the 19th century. The primary reason for this sensitivity is that an initial warming (or cooling) sets in motion a chain of events that amplify the warming or cooling. This chain of events is known as the albedo feedback.
What do you understand by environmental impact assessment?
Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse.
What is the Arctic known for?
Due to thermohaline circulation, the Arctic’s thick, reflective sea ice moderates ocean temperatures around the world. The Arctic experiences the extremes of solar radiation. During the Northern Hemisphere’s winter months, the Arctic is one of the coldest and darkest places on Earth.
Why is the Arctic important?
The Arctic is crucial for lots of reasons. Not just because it’s home to the iconic polar bear, and four million people, but also because it helps keep our world’s climate in balance. The Arctic also helps circulate the world’s ocean currents, moving cold and warm water around the globe.
How are Arctic foxes affected by climate change?
The Arctic fox faces a multitude of threats from climate change: its sea ice and tundra habitat are shrinking, its lemming prey are becoming less abundant in some areas, and it faces increased competition and displacement by the red fox which is moving northward as temperatures warm. LOSS OF SEA ICE AND TUNDRA HABITAT.
What is the Arctic climate?
The climate of the Arctic is characterized by long, cold winters and short, cool summers. The Arctic consists of ocean that is largely surrounded by land. As such, the climate of much of the Arctic is moderated by the ocean water, which can never have a temperature below −2 °C (28 °F).
