It's a tough time to be a glacier. Scientists expected Venezuela's Humboldt Glacier to last another decade, but in 2024 it melted into an ice field, shrinking to under two hectares. This marks the loss of the country's last glacier and signals a grim future for others. Scientists warn that glaciers in countries like Germany and Mexico will also disappear as fossil fuel consumption accelerates global warming. Communities depending on glaciers for fresh water face challenges, as glaciers in mountain ranges like the Andes provide vital drinking and irrigation water for millions of people.

However, about 80% of global glaciers, excluding polar ice sheets, could survive if countries rapidly reduce greenhouse gas emissions. Tropical glaciers in regions such as the Andes, East Africa, and Indonesia, however, are unlikely to recover due to higher temperatures. Despite pledges in the 2015 Paris Agreement to limit warming to 1.5°C above pre-industrial levels, current projections suggest a rise of 3°C, potentially raising sea levels by nearly 10 feet by 2100, threatening island nations like Fiji and the Maldives with destruction.

A proposal to protect ice sheets in Antarctica and Greenland involves a 62-mile-long removable underwater curtain, but experts like James Kirkham from the International Cryosphere Initiative caution that such measures are distractions from the real issue: halting global heating. Without decisive action, glaciers will continue to melt, and more countries will lose their ice. The urgency of addressing climate change has never been clearer, and the world's glaciers can't afford any more delays.

Current projections of global warming at 3°C above pre-industrial levels suggest that the human race _______.

Solution

✅ Correct Option: 1

Option 1 -> The passage states that 3°C rise could raise sea levels by nearly 10 feet, threatening island nations with "destruction," and describes a "grim future" with continued glacier loss.

Option 2 -> The passage clearly indicates temperatures are still rising (projected 3°C increase), not stopped.

Option 3 -> The passage notes "fossil fuel consumption accelerates global warming" and projections show 3°C rise instead of the 1.5°C target, indicating insufficient emission reductions.

Option 4 -> The passage explicitly states that despite Paris Agreement pledges to limit warming to 1.5°C, current projections suggest 3°C, showing non-adherence to the agreement.


Hence, Option 1 -> The 3°C projection scenario described in the passage includes catastrophic consequences: nearly 10 feet sea level rise by 2100, destruction of island nations like Fiji and the Maldives, loss of glaciers and freshwater sources for millions, and the passage emphasizes "the urgency of addressing climate change has never been clearer." These dire outcomes align with humanity being on the brink of disaster and self-destruction. -> correct
