This is the case for June 2006 and June 2023, which had similar extent sizes throughout the month, according to the National Snow and Ice Data Center Charctic Interactive Sea Ice Graph. This means that even though sea ice is declining overall, it is still possible for a more recent year or month to roughly match the extent of past months or years. However, seasonal weather and short-term climate variations also influence the size of extent, he told USA TODAY in an email. "We have over 43 years of data now, and the signal of decreasing sea ice is very clear," Walt Meier, a senior research scientist at National Snow and Ice Data Center, previously told USA TODAY.įact check: Humans are responsible for a significant amount of CO2 in the atmosphere About half of the sea ice cover at the "minimum extent" − the time of year after the summer melt has concluded − has been lost, according to the United Nations Environment Programme. Arctic sea ice decreasing overall despite variabilityĪrctic sea ice is declining overall due to climate change, according to the Environmental Protection Agency. Multiple lines of evidence show that human CO2 emissions are causing global warming. While Arctic sea ice extent − the area covered by a certain amount of floating ice − was similar in June 20, Arctic sea ice is decreasing overall due to global warming.

"Not the narrative: June 2023 Arctic sea ice extent about the same as June 2006, despite ~800 billion tons of emissions representing a 41% increase in industrial era CO2," reads the caption. The sea ice appears to cover roughly the same area in both images from the National Snow and Ice Data Center.
