This presentation was given in 2015... Speaks for itself. Prof Wadhams is a class act and knows his ice. I noticed paid troll partridge is present and accounted for. He is a man that has been studying the arctic for 40 years and this troll shows up and says he does not know what he is talking about. Isn't that special. Well, I'm sure there are more deniers that like to spew out nonsense still trolling knowledge. smh.
August 17 US naval research lab measurement of Arctic sea ice over a 30 days period shows multi year sea ice has now virtually disappeared. This mean its GONE
Functionally it's gone but not quite yet if physical measures are taken, emission reductions can't save it too slow because they deal with a limited amount of heat versus heat-sources. With today's albedo-loss it's worth 25-years of USA power compared to the previous average 1980-2010 sea-ice cover, about 3,800-TeraJoule-hours/yr for USA power = 95,000-Twh a year in energy, 1-Watt = 1-Joule. Global steam waste-heat is aout 36,000-Twh/year of directly heating the planet; to compare: 36000 ÷ 95000 = 38% of albedo-loss for impacts. We have direct control over this waste-heat and need to end the Steam Age especially using uranium and zero done about nuclear-waste just to boil water, eh? So the incentive is to not double this "heat source" of the water gaining that much a year, 95,000-Twh is a lot to counter by dropping emissions when 1/4 of what's emitted remains over 10,000-years. My solution is to dam Bering Straits to reduce the heat from it's flow to 1/100 to end that area being first to melt and last to freeze yearly to an ice refuge with ice all year.
It's funny about the temperature differential and the looping jet streams here in the United States instead of telling people what's going on they just think of a of a new word like a polar vortex
The methane source in the northern hemisphere is Metting hydrates and permafrost but also Frak Ing got started on out a lot larger scale and 2008 worldwide and mostly the northern hemisphere
Reacting to your post, this forum has up-to-date and predictive analysis ongoing, for years: forum.arctic-sea-ice.net/ ... this had daily graphs with choice of years to compare, nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/
This is dated. They make a comment about all the heating currently going into the deep ocean so it was obviously before the abrupt surface warming beginning in 2014.
It's as obvious as the nose on our faces that sea ice decline is exponential, as is temperature increase, and as Co2 rate rise is. Co2 rate rise has jumped from 3ppm per year to 6ppm per year. We have released more Co2 in the past 10 years than in the previous 200 years. We will have used the whole so called carbon budget by 2030. Its going to get toasty warm and we are not slowing down on ghg emissions, we are racing to the next mass extinction. It has warmed by 1'65'c since 1750 (pre industrial). The maths is clear that it warms by 1'c per 60ppm rise in Co2. Our emissions in the past the last 10 years are greater than the previous 200 years. We will have used the whole so called carbon budget by 2030. Our emissions guarantee warming of 3'c. Add in the Milankovitch Cycle type release of Co2 and Methane, circa 1tt/1'c of warming and that's another 2-3'c. Add in the well known self reinforcing feedback loops and that's another 2-3'c of warming. Minimum GAT (global average temperature) of 22'c. The Eastern Siberian Arctic Sea Floor contains 500-5000gt of Methane. It is already in meltdown and releasing methane. It will rise exponentially. We will have created an Anoxic Ocean Event releasing massive amounts of HS2 (Hydrogen Sulphide). All oxygen breathing animals die when exposed to HS2 gas. Time scale = Begins by 2040. The record 2014 = .14'c rise, 2015 .17'c, 2016 .22'c rise 2017 .25'c, 2018 .27'c, 2019 .3'c. = 1'c rise in 5 years. 3'c rise by 2030 = runaway Global Warming. As for the Sun causing this? delusional.

ITS GONE

I apologize I was attempting to edit my comment and accidentally hit send
well done,
I thought we were going to temporarily lose all sea ice in the Arctic by this June? What's going on? What's the actual data indicating?

1/4 is exactly right. SRF has risen from 4w/m2 to 5w/m2. That = 1/4 or 25% to me every single day.

It's May 12, 2015.
I am afraid there is no back to normality.
And I say this since 1968... sorry folks, it will be severe.

Absolutely brilliant mark/question if your time scale is accurate when do the little trees, grains, phytoplankton, come under severe stress
Not at all. Look at the temperature records
