RC: Climate Change - 2

Passage 

Direction: The passage below is accompanied by a set of questions. Choose the best answer to each question.
The Arctic is warming at a rate twice as fast as the global average, a phenomenon that has far-reaching implications for global weather patterns. The loss of sea ice, which acts as a reflective barrier sending sunlight back into space, is contributing to further warming.
This process, known as the albedo effect, is creating a feedback loop that exacerbates the warming trend. The melting of the Arctic ice is not just a local issue but has global consequences. It affects ocean currents and jet streams, leading to unpredictable weather patterns, including extreme weather events such as heatwaves, cold spells, and intense storms.
Scientists are concerned about the potential for a 'blue ocean event' - a situation where the Arctic is ice-free during the summer months. This could lead to a dramatic shift in global weather patterns, affecting agriculture, ecosystems, and human settlements. The Arctic is a critical component of the Earth's climate system, and its rapid transformation is a clear indicator of the urgent need to address climate change.
Q1: What is the primary cause of the accelerated warming in the Arctic according to the passage?
(a) Increased volcanic activity in the region.
(b) The albedo effect due to the loss of reflective sea ice.
(c) The migration of polar species to colder regions.
(d) The direct heat generated by human activities.

Q2: A 'blue ocean event' refers to:
(a) The proliferation of marine life in the Arctic.
(b) An increase in ocean salinity due to melting ice.
(c) The Arctic being ice-free during the summer months.
(d) The occurrence of intense storms in the Arctic region.

Q3: The melting of Arctic ice affects global weather patterns by:
(a) Increasing the Earth's overall temperature.
(b) Contributing to the rise in sea levels.
(c) Influencing ocean currents and jet streams.
(d) Causing a decrease in global precipitation.

Q4: The passage suggests that the transformation of the Arctic is:
(a) A local issue with limited global significance.
(b) An indicator of the need for regional environmental policies.
(c) A clear sign of the urgency to address climate change globally.
(d) A reversible process if immediate action is taken.
