Climate Change Daily Current Affairs
What is the main cause of accelerated melting experienced by northwest Greenland’s Petermann Glacier since the turn of the century?
A) Increased precipitation on the glacier
B) Infiltration of warm ocean water beneath the ice
C) Reduction in air temperature around the glacier
D) Expansion of the glacier’s surface area
Explanation: The passage states that the main culprit in the accelerated melting of the Petermann Glacier is the intrusion of warm ocean water beneath the ice.
[/expand]How did researchers map the tidal motion of Petermann Glacier?
A) Using radar interferometry data from European satellites
B) Using weather balloons equipped with sensors
C) Using underwater drones
D) By manually tracking glacier movement over several years
Explanation: The passage mentions that the UCI-led team used radar interferometry data from several European satellite missions to map the tidal motion of Petermann Glacier.

What is the average increase in melt rate experienced by the Petermann Glacier from the 1990s to the 2020s?
A) 5 meters per year
B) 7 meters per year
C) 10 meters per year
D) 15 meters per year
Explanation: According to the passage, the average melt rate of the Petermann Glacier increased from about 3 meters per year in the 1990s to 10 meters per year in the 2020s.
[/expand]What did the numerical model predict regarding the melt rates near the grounding zone cavity of the Petermann Glacier?
A) Melt rates will decrease near the grounding zone cavity.
B) Melt rates will be highest near the grounding zone cavity.
C) Melt rates will remain constant regardless of the grounding zone cavity.
D) Melt rates will vary randomly near the grounding zone cavity.
Explanation: The passage states that the model predicted melt rates to be highest near the mouth of the grounding zone cavity, greater than anywhere else in the ice shelf cavity.
[/expand]How does sea ice loss affect coastal communities in the Arctic?
A) Reduces coastal erosion
B) Increases protection from ocean waves
C) Causes greater coastal erosion due to larger ocean waves
D) Enhances tourism opportunities
Explanation: The article states that as sea ice retreats, ocean waves would get bigger, leading to greater coastal erosion, which poses a risk to communities living near the coastal region.
[/expand]What potential impact does sea ice loss have on Arctic animals?
A) Decreased predation rates
B) Enhanced breeding opportunities
C) Threats to survival, especially for seals and polar bears
D) Expansion of their habitats
Explanation: According to the article, sea ice loss poses significant impacts on Arctic animals, including seals and polar bears, as they rely on sea ice for survival.
[/expand]What is the projected timeframe for the Arctic Ocean to become ice-free for the first time?
A) 2030s to 2040s
B) 2040s to 2050s
C) 2020s to 2030s
D) 2050s to 2060s
Explanation: The article mentions that the Arctic Ocean could become ice-free for the first time on a late August or early September day between the 2020s to 2030s under all emissions scenarios.
[/expand]What is the main contributor to sea ice loss in the Arctic?
A) Volcanic activity
B) Greenhouse gas emissions
C) Ocean currents
D) Solar flares
Explanation: According to the article, greenhouse gas emissions are identified as the primary contributors to sea ice loss in the Arctic.
