Humanity is facing the final, western corporate capitalist, fossil fuel initiated, catastrophic Arctic methane hydrate destabilization and Permian style methane blowout - firestorm that will culminate in 1 to 8 years (2020 to 2027).

We will all be boiled alive like lobsters in a massively humid atmosphere and converted into stardust.

Recent data from the Arctic confirm an exponential rise in the temperature anomaly of the Arctic stratospheric methane which is now 65 degrees C above the normal, while it was only 20 degrees C above the normal, 6 to 8 years ago.

Using this data and the recent Piomass (2017) estimates of the minimum Arctic ice shelf volume it is now possible to estimate the timing of the Arctic - Permian style methane blowout firestorm more accurately and the events are tabled below.

---

1. An Arctic blue oceanic event is possible in 2020 due to the fast rise in Summer temperatures (Piomass - Zhang and Rothrock, 2003, Wipneus, 2017, Carana, 2016)

---

2. The start of the Arctic Permian style methane blowout event can begin as early as July 15, 2020 at the end of Summer in the Northern Hemisphere if the Mean Yearly Global Warming Potential of Methane is used (119.3959 from Goddard Space Flight Centre Data, NASA 2012)

---

3. The Major Arctic Permian Style, Methane Blowout - Firestorm Event which will cause the release of some 50 Gt of methane from the Arctic shelf and slope (Shakhova, 2010), a 10 Degree Centigrade Rise in Mean Global Atmospheric Temperatures causing a Catastrophic Permian Style Global Extinction Event, is timed to begin on 4th September, 2021 using an Atmospheric Methane Global Warming Potential of 100. This is an end Summer event for the Northern Hemisphere.

---

4. There is a 95% Probability that the Arctic Ice Shelf will have Zero Volume by the 5th of September 2022 (Piomass - Zhang and Rothrock, 2003, Wipneus, 2017, Carana, 2016) which is an end Summer event and exactly one year after the Catastrophic Permian Style Global Extinction Event.

This indicates a total 12 month delay in the atmospheric heat being transferred to the tropical ocean currents (e.g the Gulf Stream) and then being conducted north to heat up the Svalbard current which then destabilizes the shelf and slope methane hydrates in the Arctic ocean releasing methane to the atmosphere.

The Goddard Space flight Centre Arctic shelf data (NASA 2012) indicate a 7 month delay in Summer ocean heating and the release of methane from the Arctic shelf and slope.

The Arctic ice shelf is being melted from below so the ocean needs to be heated first by the methane in the tropical stratosphere and this heat is then transferred by ocean current to the Arctic over at least 7 months. Ice also has a large latent heat of melting adding an additional several months to the delay time for the total Arctic ice shelf melt.

WHAT YOU NEED TO DO

The start date of the Permian style global extinction event may be only 18 to 19 months away. This says that you must complete your bucket list of unfulfilled dreams before July to August 2020. A bucket list is a list of unfulfilled actions you need to complete before you die ("kick the bucket").

Do not worry about dying as it comes to all of us in the end, only this time we will all be going together. The Earth will soon after, lose all its oceans and become "Venus Like".

Empathy is organic evolution's key to group survival in a uncaring inorganic universe. Enjoy yourselves and be excellent to each other in these last days and hours on the only remaining habitable planet in this solar system.

Aaron Franklin comments:

Malcolm may be being too conservative. The Arctic has spat out the freshwater lid that allows sea ice to exist, and this may all kick off in September this year.

Biggest near term danger is to coastal communities, should the Greenland and/or Antarctic Ice sheets cascade collapse. They are poised to do this and it could produce worldwide megatsunami and 30m sea level rise in months of fast paced action. Good news is that flooding the north Atlantic and Arctic with huge icebergs of ice sheet origin should plug the methane dyke and stop the oceans being boiled. If we have enough tech capacity as after the cataclysm we can easily steer away from that cliff in the century or two grace a dryas event will afford us.

Get inland, and on high ground now! Unless you'd rather drown.

On February 10, 2017, 18:00 UTC it is forecast to be 0.1°C or 32.1°F at the North Pole, i.e. above the temperature at which water freezes. The temperature at the North Pole is forecast to be 30°C or 54°F warmer than 1979-2000, on Feb 10, 2017, 18:00 UTC, as shown on the Climate Reanalyzer image on the right.

This high temperature is expected as a result of strong winds blowing warm air from the North Atlantic into the Arctic.

The forecast below, run on February 4, 2017, shows that winds as fast as 157 km/h or 98 mph were expected to hit the North Atlantic on February 6, 2017, 06:00 UTC, producing waves as high as 16.34 m or 53.6 ft.

A later forecast shows waves as high as 17.18 m or 54.6 ft, as illustrated by the image below.

While the actual wave height and wind speed may not turn out to be as extreme as such forecasts, the images do illustrate the horrific amounts of energy contained in these storms.

Stronger storms go hand in hand with warmer oceans. The image below shows that on February 4, 2017, at a spot off the coast of Japan marked by green circle, the ocean was 19.1°C or 34.4°F warmer than 1981-2011.

As discussed in an earlier post, the decreasing difference in temperature between the Equator and the North Pole causes changes to the jet stream, in turn causing warmer air and warmer water to get pushed from the North Atlantic into the Arctic.

The image below shows that on February 9, 2017, the water at a spot near Svalbard (marked by the green circle) was 13°C or 55.3°F, i.e. 12.1°C or 21.7°F warmer than 1981-2011.

Warmer water flowing into the Arctic Ocean in turn increases the strength of feedbacks that are accelerating warming in the Arctic. One of these feedbacks is methane that is getting released from the seafloor of the Arctic Ocean. Update: The image below shows that methane levels on February 13, 2017, pm, were as high as 2727 ppb, 1½ times the global mean at the time.

What caused such a high level? High methane levels (magenta color) over Baffin Bay are an indication of a lot of methane getting released north of Greenland and subsequently getting pushed along the exit current through Nares Strait (see map below). This analysis is supported by the images below, showing high methane levels north of Greenland on the morning of February the 14th (left) and the 15th (right).

The image below shows methane levels as high as 2569 ppb on February 17, 2017. This is an indication of ocean heat further destabilizing permafrost at the seafloor of the Laptev Sea, resulting in high methane concentrations where it is rising in plumes over the Laptev Sea (at 87 mb, left panel) and is spreading over a larger area (at slightly lower concentrations) at higher altitude (74 mb, right panel).

This illustrates how increased inflow of warm water from the North Atlantic into the Arctic Ocean can cause methane to erupt from the seafloor of the Arctic Ocean. Methane releases from the seafloor of the Arctic Ocean have the potential to rapidly and strongly accelerate warming in the Arctic and speed up further feedbacks, raising global temperature with catastrophic consequences in a matter of years. Altogether, these feedbacks and further warming elements could trigger a huge abrupt rise in global temperature making that extinction of many species, including humans, could be less than one decade away.

Without action, we are facing extinction at unprecedented scale. In many respects, we are already in the sixth mass extinction of Earth's history. Up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct when temperatures rose by 8°C (14°F) during the Permian-Triassic extinction, or the Great Dying, 252 million years ago.

During the Palaeocene–Eocene Thermal Maximum (PETM), which occurred 55 million years ago, global temperatures rose as rapidly as by 5°C in ~13 years, according to a study by Wright et al. A recent study by researchers led by Zebee concludes that the present anthropogenic carbon release rate is unprecedented during the past 66 million years. Back in history, the highest carbon release rates of the past 66 million years occurred during the PETM. Yet, the maximum sustained PETM carbon release rate was less than 1.1 Pg C per year, the study by Zebee et al. found. By contrast, a recent annual carbon release rate from anthropogenic sources was ~10 Pg C (2014). The study by Zebee et al. therefore concludes that future ecosystem disruptions are likely to exceed the - by comparison - relatively limited extinctions observed at the PETM.

An earlier study by researchers led by De Vos had already concluded that current extinction rates are 1,000 times higher than natural background rates of extinction and future rates are likely to be 10,000 times higher.

from the post 2016 well above 1.5°C

As above image shows, a number of warming elements adds up to a potential warming of 10°C (18°F) from pre-industrial by the year 2026, i.e. within about nine years from now, as discussed in more detail at the extinction page.

Above image shows how a 10°C (18°F) temperature rise from preindustrial could be completed within a decade.

Warning of mass extinction of species, including humans, within one decade. The forecast for February 10, 2017, 18:00 UTC is that it will be 32.1°F or 0.1°C on North Pole, i.e. above freezing...

Across the oceans, the August 2015 globally-averaged sea surface temperature was 0.78°C (1.40°F) above the 20th century average—the highest temperature for any month in the 1880–2015 record. NOAA analysis further shows that in August 2015, the sea surface on the Northern Hemisphere was 1.02°C (1.84°F) warmer than it was in the 20th century, as illustrated by the graph below.

As the image below shows, the August data for sea surface temperature anomalies on the Northern Hemisphere contain a trendline pointing at a rise of 2°C (3.6°F) well before the year 2030. In other words, if this trend continues, the Northern Hemisphere sea surface will be 2°C (3.6°F) warmer in about a dozen years time from now.

Such a temperature rise would be catastrophic, as there are huge amounts of methane contained in the form of hydrates and free gas in sediments under the Arctic Ocean seafloor. A relatively small temperature rise of part of these sediments could cause a huge abrupt methane eruption, further speeding up local warming and triggering further methane eruptions, in a spiral of runaway warming that will cause mass destruction and extinction, as described in the reference page The Mechanism.

The situation is dire and calls for comprehensive and effective action, as discussed at the Climate Plan page.
