Researchers relied on satellite data to calculate the sea ice volume across the Arctic between 2010 and 2014\. (Unlike the South Pole, the North Pole is entirely ocean, albeit frozen, and the sea ice generally expands in the winter and contracts in the summer.) The ice volume decreased by 14% between 2010 and 2012, but then shot up in 2013 and 2014\. Ice volume had increased by 33% and 25% when measured in the fall of those two years than in the three years prior, according to the study. Relatively cool temperatures in 2013 and less melting during summer months led to higher levels of ice. That year the summer was cooler in the Arctic than in 2012. **Read More**: [Here’s Where to Buy a House In the U.S. That Will Be Resilient to Climate Change](http://time.com/3964807/climate-change-resilience/) Researchers described the finding as a significant aberration, but one that doesn’t change the long-term melting of the Arctic sea ice. Summer Arctic sea ice has declined by about 40% since satellite measurements began in the 1970s. Now, the planet is headed for a “seasonally ice-free Arctic,” according to Mark Serreze, director of the National Snow and Ice Data Center. “It’s not going to be a smooth transition. It’s going to be in fits and starts,” he said. “That’s just the nature of the beast.” And while the researchers said the anomalies suggest that Arctic sea ice may be “more resilient than has been previously considered,” they were also quick to emphasize that the Arctic is not undergoing a broader recovery. “We don’t want it to be seen as any kind of recovery,” said study author Rachel Tilling, a researcher at University College London. “It really is just one anomalous year.” In addition to affecting activities like oil and natural gas operations in the area, Arctic sea ice thickness and volume have the potential to influence the climate and weather in a number of ways, including ocean circulation and weather patterns. “We hope that these measurements can help all these models that are used to predict future climate change,” said Tilling. ## Transcript [ MUSIC ] Extreme weather was more frequent in recent years. Is it a sign that global warming is gaining pace and exceeding predictions? Now, has extreme weather been more frequent in recent years? The evidence is definitely to the contrary. The United States has always had extreme weather. We look back on our weather history. It's been punishing. Floods, droughts, tornadoes, hurricanes, great forest fires. Is global warming happening? No doubt about it. We're living in a warmer world. We're living in a melting world, sea levels are rising. Now, direct evidence of the foot print or the finger print of global warming, we're seeing more frequent, more intense and longer lasting heat waves. As far as hurricanes, tornadoes, forest fires, floods and drought; the evidence is definitely not in. The consensus among almost all scientists is, is that it's a small finger print, not a large foot print. But what is true is that in this country, in the United States, we live in many areas with great risk to drought, [ NOISE ] to tornadoes, to hurricanes. And so part of the dialog is not only extreme weather and global warming but is the amount of risk we can tolerate. Now, looking to the future, global change, global warming it definitely is accelerating and it will have an impact on extreme weather. But at this point, not much.
