A NASA Gulfstream V plane captured an aerial view of icebergs and ice sheet in the Baffin Bay near Pituffik, Greenland on July 19, 2022. The image serves as a stark reminder of the drastic changes occurring in the Arctic region over the past two decades.
The latest installment of NOAA’s annual Arctic Report Card paints a bleak picture of a rapidly warming Arctic. Temperatures have skyrocketed, with the summer of 2024 marking its second-warmest permafrost temperatures and second-hottest overall year on record. This is not an isolated incident; the Arctic has been experiencing a long-term pattern of transformation, with conditions diverging from historical norms.
“The Arctic exists now within a new regime, in which conditions year after year are substantially different than just a couple of decades ago,” said Twila Moon, scientist with the National Snow and Ice Data Center and lead editor of the report. “Yet climate change is not bringing about a new normal. Instead, climate change is bringing ongoing and rapid change.”
The Arctic Report Card has been issued annually since 2006, providing regular documentation of the region’s evolution. The first installment warned of melting sea ice, thawing permafrost, and “hot spots” across the region. Nearly two decades later, studies have confirmed that the Arctic is warming at least three times faster than the global average.
Sea ice has continued to sharply decline, while permafrost has thawed across large swaths of Alaska, Canada, and Siberia. Wildfires are on the rise, and scientists have confirmed that the Greenland ice sheet is losing tens of billions of tons of ice every year. The region’s wildlife populations are also affected, with some species adapting to the changing conditions.
However, not all species are thriving. Caribou migratory tundra caribou populations have declined by 65% over the last 20-30 years, down from a peak of 5.5 million in the 1990s and 2000s. The declines are attributed to rising temperatures, which increase the odds of freezing rain events that can cover up the plants caribou depend on for food.
The new report card highlights the need for rapid global reductions in greenhouse gas emissions. “While we can hope that many plants and animals will find pathways to adaptation, as ice seals have so far, hope is not a pathway for preparation or risk reduction,” said Moon.
As the Arctic continues to transform, it serves as a stark reminder of the urgent need to address climate change. The region’s unique ecosystems and indigenous communities are facing unprecedented challenges, and the consequences will be felt globally if action is not taken. With almost all human-produced heat-trapping emissions created outside of the Arctic, only the strongest actions to reduce these emissions can minimize risk and damage.
The Arctic’s transformation is a warning sign for the world, a stark reminder that the clock is ticking on climate change.
