Arctic Ocean and Greenland ice sheet see record June melting

[h=3]Early July Arctic ice volume on the rise![/h]Also early July Arctic sea ice has refused to melt further for 15 years now.

Japanese climate blogger Kirye plotted the data back to 2006, and we see an upward trend for July 8 Arctic sea ice volume:

[h=3]Growing ice over past 10 years[/h]The rising trend becomes even pronounced when we look at the last 10 years. This ice cold reality flies in the face of all the wild claims of a melting Arctic we often hear in the media.

Wintertime Arctic Sea Ice Growth Slows Long-term Decline: NASA | NASA

As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year.

But at the same time that sea ice is vanishing quicker than it has ever been observed in the satellite record, it is also thickening at a faster rate during winter. This increase in growth rate might last for decades, a new study accepted for publication in Geophysical Research Letters found.

This does not mean that the ice cover is recovering, though. Just delaying its demise.

"This increase in the amount of sea ice growing in winter doesn’t overcome the large increase in melting we've observed in recent decades," said Alek Petty, a sea ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study. "Overall, thickness is decreasing. Arctic sea ice is still very much in decline across all seasons and is projected to continue its decline over the coming decades. "

No decline for 15 years.

Yes, the usual seasonal cycle.

Right. And 2019 is pretty much tied with the lowest extent ever, and I believe finished June with the lowest ever recorded that month.

But hey...you read a denier blog, so there’s that.

Negligible difference. Easier to see in this presentation.

That's what the DMI data show.

That top grey line looks like there used to be more ice. Every other year is under it, for every month. That's a lot of ice melted - it would cover half of the US continent is what I've read.

That's not data, that's model output. You can't actually measure ice volume.

It's also a ridiculously short timescale, given the annual variation. The error bars on that must be enormous!

You really should stick to actual scientific websites, Jack, rather than trusting propaganda blogs.

Looks like data to me. Maybe DMI knows more about this than you do.

LOLwut?

Sea ice extent and coverage are directly observed.

But that’s science, so you wouldn’t know that.

They are indirectly observed by satellites, which drift in accuracy, and we have no way to properly calibrate them. I think they get "corrected" to what the models tell them they should read, like other things being corrected.

There is no way to know if the corrections are correct!
