Greenland's ice sheet just lost 11 billion tons of ice -- in one day

Moving house *now* might be a better plan!

It hasn't been "lost" at all; just temporarily changed from solid to liquid - and just as likely to change back again come winter. Sheesh!

A related thing I have wondered bout.

With tree rings a new ring is added every year so it is easy (at least with a microscope) to calculate the age of the tree or wooden structure to an accuracy of one years. If tree ring data is available from trees that have lived at different but overlapping periods, tree ring data series have been reconstructed for up to about the last

One would think that glacial ice cores would be as accurate. If there are no significant melting during summers this would be the case.

However, if the last few years have been cold and hence there are nice ice core rings but then there is a warm summer, which say, melts 60 cm of ice (as apparently in the current case), multiple years of previous ice core data will be destroyed. If the molten water remains in an ice lake, it will freeze again during the winter, fusing multiple years of ice ring data into a single layer. Alternatively, if the melt water escapes through crevasses to the ocean, ice data for several years will be completely lost.

Admittedly, if the ice core contains contamination, e.g. ash from well known vulcan eruptions, it might be possible to recreate timing before that vulcan event. But if there are no such clear years with external contamination ...

Prayer causea ice agea? Skepticism is appropriate.

No, installation of instruments does not cause record heat.

No, 'badly sited' is not an important issue, unless you believe that no discrimination between sites is implemented.

What on earth does 'badly maintained' mean? You can't collect coherent data from nonworking stations, and incoherent data is routinely excluded from calculations.

With more stations reporting, the averages are LESS noisy than with few reporting, not more noisy. Learn statistical thinking, or provide some kind of argument for 'setting records' that relates to reality in a rational premises-and-logic fashion.

Not all of it. Liquid water does run off, and the Greenland ice sheet is lo sing mass from year to year - the winter snowfall isn't making up for the w ater that runs off every summer.

The real worry is that the rivers of warm water that flow down through gaps in the ice sheet are eroding the ice sheet, and setting it up to slide off into the ocean in big chunks, which is how ice sheets end up raising sea l evels quite rapidly as they disintegrate.

So 280 Gt is lost every year. With 11 Gt daily melting according to the subject line, that is 25 days of melting i.e. less than a month. The melting period was at least 4 months so at least 3/4 is restored during winter.

A lot of ice was accumulated during the little ice age (LIA) which is now melting away and apparently soon medieval warm period (MWP) levels are reached. No need for panic.

So there are three North Poles, one at 90N, the magnetic pole currently in Northern Canada (is it actually North or South pole :-) and the North Pole willage/town in Alaska :-).

No, there at least are 4 of them.

North Pole, the hotel in Muktinath, northern Nepal. Probably the coldest of all of them. :-(

The name should have been a warning. No, no hot anything.

You left out Santa's Workshop...

You forgot Ollie's North Pole too! Been around 75 years.

skiing all year around is boring.

Why not ski in the winter and water skiing in the summer :-)

In the current development we finally get away with multiyear ice from glaciers as well as from the Arctic Sea that has accumulated during the LIA.

At high latitudes there are going to be ice and snow only during the winter and warm and comfortable during the summer:-).

The little ice age and the medieval warm period were essentially local even ts.

Anthropogenic global warming is world-wide, though the Arctic happens to be warming up faster than most places.

The problem is relatively long term, so there is no need to panic, but we'd be much wiser to tackle it now before it has a chance to proceed to panic- justifying dimensions.

aps in the ice sheet are eroding the ice sheet, and setting it up to slide off into the ocean in big chunks, which is how ice sheets end up raising se a levels quite rapidly as they disintegrate.

When that starts happening, it will be a bit late to panic. It doesn't look as if it going to happen all that soon, but all the interesting stuff is h appening a mile or so of ice, so we don't know all that much about it.

I can barefoot water ski. The problem is logistics. I have not gone water skiing in decades.

BOAT means "break out another thousand".

Hey I know! We should do like the ice worms do and dig tunnels (ice amusement parks) in the galciers and have fun on icy water slides!

Dig way down and the temp is the same all year.

I am surprised that Antarctic domains are not buried so as to be out of the chilling winds.

Well, there's the problem. Records aren't averages, they are spot measurements. With more measurements, you're going to have more extremes.

The alarmist newspapers report single-site peaks as "record" temperatures.

And urbanization makes the averages go up, too.

Truckee use to often, in the summer, have the record low temp in the lower 48. But there is a new weather station at Boca Reservoir, a few miles away, and now it wins.

Away from the trees, at that altitude at night, there's serious radiation cooling. The Stevenson box is probably painted with latex paint, basically black at thermal wavelengths. They are cheating.

More weather stations, all logging 24/7, generate more records.

Wadhams is projecting an ice free arctic by mid-September of this year base d on an extrapolation of the current rate of decline and a bunch of other u n-quantifiables that are seriously damaging and known to be happening:

Sea ice melting is accelerating for a number of reasons:

Ocean Heat - Much of the melting of the sea ice occurs from below and is ca used by heat arriving in the Arctic Ocean from the Atlantic Ocean and the P acific Ocean. The inflow of heat can increase strongly as winds increase in intensity. Storms can push huge amounts of hot, salty water into the Arcti c Ocean.

Direct Sunlight - Hot air will melt the ice from above and this kind of mel ting can increase strongly due to changing wind patterns. Numerous feedback s will further speed up melting, such as that heating will change the textu re of the sea ice at the top and that melt pools will appear, both of which will cause darkening of the surface.

Rivers - Heatwaves over land can extend over the Arctic Ocean and they also heat up river water flowing into the Arctic Ocean.

Fires - Changing wind patterns can also increase the intensity and duration of such heatwaves that can also come with fires resulting in huge amounts of greenhouse gas emissions, thus further speeding up the temperature rise, and also resulting in huge emissions of soot that, when settling on sea ic e, speeds up melting.

The Earth is well on its way to an 8oC temperature rise shortly.

It's not about sea level rise.
