What is the reason that the Arctic is warming much faster than the lower lattitudes in simple terms?

Is that what they call 'Arctic Amplification'?

It is still being debated.
Taylor's research shows that the seasonality of the polar warming is largely a result of energy in the atmosphere that is being transported to the poles through large weather systems.

The importance of energy transport in the warming of the poles suggests more study is needed on the interactions between large weather systems and more local changes, involving clouds, water vapor, surface albedo and atmospheric temperature, in order to better understand climate sensitivity.

"We hope to learn more about the processes involved in atmospheric processes in order to better understand what climate models are telling us," Taylor said.

Base line on the above data is very recent, already abruptly changed, heated up.
Better based on the changes from the average last century or so.
Yes still below freezing H2O but it is the extremes that matter, rain events on the pole, summer sea ice exit, those happening will push the Arctic climate out of balence and once it is far enough from normal it is impossible to return to the stable state.
Until a new state, hothouse without ice, the end of ice.

There might be discussion on how fast it, AAmp. is going faster but the causes are known, all those feedbacks upon feedbacks, albido/methane/jet/PV/snowcover/currents…...the pole is the weak link in the stable climate we used to enjoy.

A new international research study on the cause of Arctic amplification published this week in the journal Nature Climate Change shows that local greenhouse gas concentrations, and Arctic climate feedbacks outweigh other processes. Using complex computer simulations, the scientists were able to disprove previously suggested hypotheses, that emphasized the role of transport of heat from the tropics to the poles as one of the key contributors to the amplified warming in the Arctic.

"Our study clearly shows that local carbon dioxide forcing and polar feedbacks are most effective in Arctic amplification compared to other processes," said corresponding author Malte Stuecker, project leader at the IBS Center for Climate Physics (ICCP) in Busan, South Korea.

OK, not so really simple, as it is almost never so simple:

In the tropics—fueled by high temperature and moisture—air can easily move up to high altitudes, meaning the atmosphere is unstable. In contrast, the Arctic atmosphere is much more stable with respect to vertical air movement. This condition enhances the CO2-induced warming in the Arctic near the surface. In the tropics—due to the unstable atmosphere—CO2 mostly warms the upper atmosphere and energy is easily lost to space. This is opposite to what happens in the Arctic: Less outgoing infrared radiation escapes the atmosphere, which further amplifies the surface-trapped warming.

"Our computer simulations show that these changes in the vertical atmospheric temperature profile in the Arctic region outweigh other regional feedback factors, such as the often-cited ice-albedo feedback" says Malte Stuecker.

After listening to this ep with Dr David Suzuki, you’ll never be the same again. The environmentalist, activist, professor of genetics and science broadcaster hits us with some home truths about what our future will look like if we continue to live the way we have been. What will life be like for our children and grandchildren? Can the damage we’ve done to the planet be reversed? Is extinction of the human race imminent?

We talk about population control, the importance of renewable energy and discuss what we can do right now in our own lives that can actually make a difference. This is for anyone who cares about the future of mankind.

The unrelenting increase in global levels of atmospheric methane went literally off-the-charts used to display methane for the Copernicus Atmospheric Monitoring Service (CAMS). Methane levels were so high that they swamped out the colour scheme used in the map legend, causing saturation in large red blobs with little detail. The colour legend was shifted by 100 ppb to more clearly show the detailed structure of where methane was being emitted.

https://www.nature.com/articles/s41598-018-35068-1

Climate change and human activity are dooming species at an unprecedented rate via a plethora of direct and indirect, often synergic, mechanisms. Among these, primary extinctions driven by environmental change could be just the tip of an enormous extinction iceberg. As our understanding of the importance of ecological interactions in shaping ecosystem identity advances, it is becoming clearer how the disappearance of consumers following the depletion of their resources — a process known as ‘co-extinction’ — is more likely the major driver of biodiversity loss. Although the general relevance of co-extinctions is supported by a sound and robust theoretical background, the challenges in obtaining empirical information about ongoing (and past) co-extinction events complicate the assessment of their relative contributions to the rapid decline of species diversity even in well-known systems, let alone at the global scale. By subjecting a large set of virtual Earths to different trajectories of extreme environmental change (global heating and cooling), and by tracking species loss up to the complete annihilation of all life either accounting or not for co-extinction processes, we show how ecological dependencies amplify the direct effects of environmental change on the collapse of planetary diversity by up to ten times.




Does make you wonder if even sturdy trilobites are able to make it through the bottleneck :(

Being in the midst of the sixth mass extinction1, it is fitting to quantify the relative contribution of different mechanisms driving catastrophic biodiversity loss. Drivers directly related to anthropogenic modifications of the biosphere are apparent and well-described: habitat destruction, over-exploitation, and biotic invasions2. Similarly, the effects of environmental change (e.g., temperature rise, increased droughts, ocean acidification, et cetera) can be easily interpreted — when the environmental conditions of a certain locality become incompatible with the tolerance limits of inhabiting species, in many cases these will go locally extinct, just like fish in an aquarium with a broken thermostat (even if there are counter examples of species that have been capable of rapid adaptation to novel environmental conditions3). Yet, there are other, more complicated mechanisms that can exacerbate species loss. In particular, it is becoming increasingly evident how biotic interactions, in addition to permitting the emergence and maintenance of diversity, also build up complex networks through which the loss of one species can make more species disappear (a process known as ‘co-extinction’), and possibly bring entire systems to an unexpected, sudden regime shift, or even total collapse4,5,6,7,8,9.


This makes it difficult to be optimistic about the future of species diversity in the ongoing trajectory of global change, let alone in the case of additional external, planetary-scale catastrophes. A previous study14 contended this idea by using the remarkable tolerance of tardigrades to extreme temperature, pressure, and radiation as a reference to calculate the likelihood of global sterilization on an Earth-like planet following different, dramatic astrophysical events. The stunning conclusion of that study is that life on our planet has the potential to survive asteroid impacts, supernovae, and gamma-ray bursts14. This ostensibly reassuring news highlights how some scientists still tend to disregard the role of co-extinctions within collapsing communities in driving global biodiversity loss, while focusing on individual species’ tolerance limits as the only criteria relevant to species survival in a changing world. Ecologists know the optimism is not supported quantitatively, but can we estimate the magnitude of the bias?
Here we attempt to do this by combining real-world ecological and environmental data to generate several virtual Earths populated by interconnected species-interaction networks where we allow species to move and adapt, that we then subjected to extreme, global environmental change. By comparing scenarios of extinctions based only on species’ environmental tolerances with others accounting also for co-extinctions, we show that neglecting to consider the cascading effect of biodiversity loss leads to a large overestimation of the robustness of planetary life to global change.


Oops, I meant tardigrades, just not read the whole intro and wondering about trilobites…they were ancient life now well down under lots of Earth right?


Difficult to be optimistic :-D Understatement of the year :-D

Amazing that this comes out on nature.com, scientific community is waking up, just in time I suppose, to face doom openly :roll:

Here's a critique of many of McPherson's arguments.

https://fractalplanet.wordpress.com/201 ... -it-wrong/

His near-term extinction scenario seems mostly based on the theory that abrupt warming in the Arctic ocean will inevitably trigger a sudden massive methane release from the East Siberian seabed. However, I read somewhere that these methane clathrates are dozens or even hundreds of meters deep under the seabed and that any extra warming of the ocean, however dramatic, takes many decades or more than a century to penetrate so deep into the seabed.

Fredrik, you need to read the many threads of Runaway Global warming on this site. In them you can peruse the many commentaries from Cid Yama synthesizing what some scientists are saying is happening in the East Siberian Arctic Shelf. Suffice to say we are talking about a substantial amount of disassociated methane just below the permafrost in danger of being released because this permafrost is melting under current conditions there.

As for Guy's personal affairs, completely irrelevant to his assertions

I remember the panicked talk about an imminent large-scale methane release in 2011, after the Semiletov/Shakova report with the huge methane plumes and the oft-quoted 50 gigaton scenario. So far, methane levels have only risen by a few percent since, despite record warming in the Arctic. Most climate scientists seem to expect a similar slow increase of methane from the Arctic region during the decades to come.

And the subsea permafrost has been slowly thawing for millennia after the East Siberian Arctic Shelf got inundated, so this theoretical threat of 50 gigaton release has been there for maybe thousands of years. IIRC, the thaw now reaches several dozens of meters deep, so any additional heat from the warming waters takes quite some time to permeate deeper than that.

An update on the Arctic Warm Wedge:

https://earth.nullschool.net/#current/w ... 532,72.063

https://earth.nullschool.net/#current/w ... 039,80.075

Plus .8 degrees at 80.08 degrees NL! Free of ice I suppose.
Minus 3 degrees Celcius at the Bering Sea, still freezeng, around minus 8 at the Northpole. Once the cold blob on the arctic ocean is split up, between Canada and Russia, it will be hard for the relic sea ice to form and stay intact.

https://seaice.uni-bremen.de/data/amsr2 ... R2_nic.png

Barentz sea almost complete free of sea ice, large gap North of Spitsbergen, arctic turning into atlantic regime, an abrupt regime change of the climate.

Guy is saying we should pay attention and live with death in mind, be excellent every day and night as if it is your last little dance on this Earth, this magical place, he is telling we should brace ourselves for this change will speed up with the absence of our dirty global shield, Global Dimming or the loss of sea ice that will probably plunge us into a hothouse.
That 50 Gton from Shakova, free methane underneath the subsea permafrost of the ESAS comes to mind 8O
Even without abrupt CC, it is really better to stop living as if we are immortal beings, let death be your advisor every moment, to let you make the best decision before you act like a petty tyrant and hurt yourself and others around you.
Heck, I am an optimist, I think we are not as stupid as we do, think we are.
I think we are misled which is not an excuse or judgement.
