The Danish Meteorological Society has not posted the temperature for above 80 deg. since May 2 when it crossed the line to below average. What do you suppose is going on? http://ocean.dmi.dk/arctic/meant80n.uk.php

Day 127 MASIE Arctic extent still above 2006, 2007, 2009, 2010, 2011, 2015, 2016

NSIDC Arctic above 2004, 2006, 2015, 2016

Antarctic, still above 1980, gaining slowly towards previous decadal minimums
(This is a single year anomaly, like 1980 was, in an otherwise increasing trend.)

• AndyG55 says:

Note, eyeballing the MASIE and NSIDC graphs, it seems that, at this stage, this year’s melt is rather SLOWER than most previous years.

Thanks Tony for another lie busting video.

LOL
“It is hard to make people understand when the salary..”

If You want to find high temperature anomalies look at Arctic during winter.
If You like to understand why look at ice cover.
If You think that it is warming the globe -try harder!

Getting Hotter And Drier? No, but Drier will be Hotter with the same energy input.

Specific Enthalpy of Dry Air – the Sensible Heat

For air temperature between -100oC (-150oF) and 100oC (212oF) the specific heat can be set to

cpa = 1.006 (kJ/kgoC)
= 0.240 (Btu/lboF)

Specific Enthalpy of Water Vapor – the Latent Heat
Assuming constant pressure conditions the specific enthalpy of water vapor can be expressed as:

hw = cpw t + hwe

in metric units – h = (1.006 kJ/kgoC) t + x [(1.84 kJ/kgoC) t + (2501 kJ/kg)]
in Imperial units – h = (0.240 Btu/lboF) t + x [(0.444 Btu/lboF) t + (1061 Btu/lb)]

Also dry air cools a lot faster too, see the number of US State Record Low Temperatures set in the 1930’s
