Larsen C Crack Is in Its Final Stages; Will Produce One of World's Largest Icebergs Ever Recorded

I say they can pee up a rope.

 

What is the correct average global temperature supposed to be?

You won't answer that specific question because there is no correct answer.

 

They aren't, because the goals are monetary. We can reduce all the emissions we like. We can match or exceed their efforts if we choose. That will not make them happy, because this was about redistribution of wealth.

We do not require a non-binding agreement to reduce emissions. They are just pissed about the money.

 

Excellent! Earth continues to recover from the Little Ice Age, and if our luck holds, may recover to the nice warm balmy temperatures of the early 1400's!

 

It's still not abnormal by any stretch of the imagination.

The figure 57.2°F came from this site:

How warm was Greenland during the last interglacial period?

The NEEM paradox has emerged from an estimated large local warming above the preindustrial level (7.5 ± 1.8 °C at the deposition site 126 kyr ago without correction for any overall ice sheet altitude changes between the LIG and the preindustrial period) based on water isotopes, together with limited local ice thinning, suggesting more resilience of the real Greenland ice sheet than shown in some ice sheet models. Here, we provide an independent assessment of the average LIG Greenland surface warming using ice core air isotopic composition (δ15N) and relationships between accumulation rate and temperature. The LIG surface temperature at the upstream NEEM deposition site without ice sheet altitude correction is estimated to be warmer by +8.5 ± 2.5 °C compared to the preindustrial period. This temperature estimate is consistent with the 7.5 ± 1.8 °C warming initially determined from NEEM water isotopes but at the upper end of the preindustrial period to LIG temperature difference of +5.2 ± 2.3 °C obtained at the NGRIP (North Greenland Ice Core Project) site by the same method.

According to that peer-reviewed study published September 2016, the temperature at Greenland was 8.5°C or 15.3°F warmer than present.

Then there's this:

For warmer climates, an analyse of several long (340 kyr) ice core records from across East Antarctica, alongside input from isotopic GCM modelling, indicated that for warmer interglacial periods, conversions vary between different East Antarctic ice core sites (Sime et al. 2009). Results indicate that the East Antarctic water isotopes tend to be less sensitive to temperature changes during warmer climates. This indicates that previous temperature estimates from interglacial climates are likely to be too low. The available evidence is consistent with Antarctic interglacial temperatures that were significantly (more than 6°C) higher than present day.

6°C corresponds to 10.8°F

Oh. yes, of course, the instruments sitting on black-topped surfaces or on black-tarred roof-tops.

Then what is the point?

8.5°C corresponds to 15.3°F.

What do you supposed happened to the Greenland Ice Sheet when temperatures increased 15.3°F?

It damn near melted in its entirety.

 

So you couldn't refute my figures....got it.
