Claim:
Arctic sea ice is not melting and there is no indication that we should expect the Arctic sea summer ice to disappear completely, as predicted
Claim:
CO<sub>2</sub> is not the cause of our current warming trend; Arctic sea ice has expanded in recent years; Polar bears’ population is growing and is not threatened by climate change; CO<sub>2</sub> is good for plant life
Human-caused climate change is already accelerating Greenland’s melting and is predicted to continue to accelerate it in the future. In addition to Greenland, most glaciers around the planet are also melting at an accelerating pace. This melt, in addition to the expansion of the ocean as it warms, contributes to elevate sea level at an accelerating rate, threatening coastal cities around the globe.
“The decreases have accelerated since the 1990s and have been part of a consistent suite of changes in the Arctic, including rising atmospheric temperatures, melting land ice, thawing permafrost, longer growing seasons, increased coastal erosion, and warming oceans. Overall, it has been a consistent picture solidly in line with the expectations of the warming climate predicted from increases in greenhouse gases. In particular, modeled sea ice predictions showed marked Arctic sea ice decreases, and the actual decreases even exceeded what the models predicted.”
“This article’s claim that methane deposits in the Arctic Ocean are starting to be released, awakening a “sleeping giant”, cannot be supported by the limited observational data. Besides, even if these newly found seeps are increasing, they are located too deep in the ocean to have a significant impact on the concentration of methane in the atmosphere.”

Over the past decade, a growing body of research has proposed ways in which rapid Arctic warming can lead to harsh winters, summer heatwaves and even floods and droughts across the mid-latitudes. Some scientists say that climate change and Arctic sea ice loss are the root cause of these events, but others are more circumspect. In this detailed Q&A, scientists discuss the potential connections between Arctic warming and extreme weather across the mid-latitudes, what those theories look like, and how the evidence measures up.
“This article accurately describes the Arctic warming event and associated surprise by scientists, includes multiple explanations for possible causes, and does not overstate any connections to climate change, pointing out that more data is needed to know if these above-freezing events will be a new Arctic normal.”
