A climatologist tracks Arctic sea ice, which is shrinking by 13% annually. If the ice cover was 14 million km² in 2020, what will it be in 2025 assuming continuous exponential decay?
["Arctic Sea Ice Shrinking at 13% Annually: What Will the Ice Cover Be in 2025?", "Climate change is reshaping Earth’s polar regions at an alarming pace, and the Arctic exemplifies this crisis. A leading climatologist tracking sea ice dynamics confirms that the Arctic sea ice is shrinking by approximately 13% each year due to rising global temperatures. Reporting on long-term trends, scientists use exponential decay models to project future ice coverage—offering critical insights for climate policy and environmental planning.", "### The Data: 14 Million km² in 2020", "Since 2020, satellite observations and climate models reveal the Arctic sea ice extent has declined steadily.
