NSIDC daily Arctic sea ice extent numbers have this year ~30k lower than 2012 for the same day. Pretty unfavorable pattern for Arctic sea ice retention going forward with the rest of the melt season, so this year is still in the running for a new record low. Well below every other year as well at this point, so I think at least 2nd lowest is a virtual lock at this point. |

Looks like NSIDC will numerically finish at 2nd lowest, though not statistically significantly different from 2016 and 2007. Long term decline continuing unabated. |

Help me understand how if the polar caps are melting and they are floating in the ocean. How can the water rise? Unless they are touching the ground? It’s mathematically impossible for sea level to rise if the weight has already distributed. This honestly is confusing, I’m not trying to say it’s not true. I just don’t understand how that would work, we aren’t adding water or weight because the weight has already been there floating, therefore the water is already where it would be. |

Sea ice extent does not affect the sea level rise, but is an indicator of warming, which has various other concerns. Arctic sea ice is critical to the survival of the polar bear, for example, in addition to indicating impact on the grounded Greenland glaciers, which will affect sea level rise as a result of their melting. Antarctic sea ice indicates the impact on the glaciers, which are grounded and their melting will affect sea level rise as a result. |
