Suppose that your mom is sick. None of her brothers, sisters or children have taken her complaints seriously. Everybody has carried on with their own busy lives, thinking that mom was imagining things, and assuming that she was fine. And then she took a turn for the worse. Everybody close suddenly realized that she was very frail and ill, depleted of her energy and resources. She was no longer the ageless, sacred source of life that nurtures all living beings. Now, suppose that she is everyone’s mother. She is Mother Earth. And her illness is abrupt climate change ~ Paul Beckwith
Abrupt Climate Change
Never before in human history have we faced such a global-reaching upheaval like that underway today from early stages of abrupt climate change. Will humanity continue its haphazard and disconcerted feeble attempts to address the gut-wrenching disruption and pretend that everything will work out fine as we spiral into civilization collapse? Or will we finally do what is required and treat the system turmoil as a global emergency far larger than we have ever faced before, and throw all our resources into surviving it?

Excerpts of Paul Beckwith’s interview with Will Fox of FutureTimeline.net.
Future Timeline: It’s clear that the Arctic is melting rapidly and this trend is likely to continue. When do you predict the Arctic will start to have ice-free conditions? At what point during the year will it disappear, and for how long? How will these conditions develop in future decades, and could we reach a point where the Arctic is free of ice all year round?
Paul Beckwith: I think that the Arctic will start to have ice-free conditions at the end of the melt season (Septembers) as early as 2020 or before (possibly even the summer of 2016). It is hard to predict a single year, since the loss of Arctic sea ice greatly depends on local Arctic wind and ocean conditions in the summer melt season.
For the sake of argument, let us pick September 2020 for the first “blue-ocean” event in the Arctic. This would occur for about a month. Within two or three years, it is highly likely that the duration of this “blue-ocean” state would be three months or so, thus occurring for August, September and October in 2023. Within an additional few years, say by 2025, it is highly likely that the “blue-ocean” event would be extended for another few additional months, and we’d have ice-free conditions from July through to and including November — or five months of the year. Then, within a decade or two from the initial 2020 event we can expect to have an ice-free “blue-ocean” Arctic year round — some year between 2030 and 2040.

Future Timeline: In recent years, there’s been a lot of talk about methane eruptions in the Arctic and Siberia. How serious is this, in terms of its potential for adding to global warming? Can you give us some idea of the timescales involved? What’s the level of certainty about these future effects?
Paul Beckwith: Once the Arctic is essentially ice-free for ever-increasing durations in the summer months, and then over the entire year, there are two enormous feedback risks that we face — Methane and Greenland.
Methane is the mother of all risks. The Russians have measured large increases in emissions from the continental shelf seabed in the Eastern Siberian Arctic Shelf (ESAS). Over the timespan of a few years, they observed that methane bubbled up in vast numbers of plumes that increased in size from tens of metres in diameter to hundred and even thousand metre diameter plumes in the shallow regions of ESAS. Global atmospheric levels of methane are rapidly rising, and although they average about 1900 ppb or so, there have been readings over 3100 ppb in the atmosphere over the Arctic. Since the Global Warming Potential (GWP) of methane versus carbon dioxide is 34x, 86x and close to 200x on timescales of 100 years, 20 years and a few years, respectively, a large burst of methane can virtually warm the planet many degrees almost overnight.
Recently, we have passed about 405 ppm of CO2, with a record rise of 3.09 ppm in 2015 alone. When accounting for methane and other greenhouse gases and putting them into CO2-equivalent numbers, we are at about 490 ppm CO2 equivalent. We are literally playing with fire, and the outcome will not be pretty.
Greenland ice melt is the next enormous feedback risk. When we lose snow and ice in the Arctic – and the cascading feedbacks like albedo destruction kick in – and the methane comes out, then the enormous warming over Greenland and in the water around and under the Greenland ice will viciously destroy the ice there and greatly accelerate sea level rise.
Future Timeline: How does the melting in the Arctic compare to its southern polar opposite, the Antarctic?
Paul Beckwith: The Arctic is rapidly losing snow cover (mostly in the spring months) and sea ice cover, and thus the average albedo (reflectivity) of the region is rapidly decreasing. This is feeding back into additional Arctic Temperature Amplification and further darkening and warming, until we have no snow and ice in the region.
These vicious feedback cycles have not kicked in to the same extent in the Antarctic. The ice cap there is losing ice causing a rise in sea level mostly from the warming of the seawater undercutting the ice on land that is grounded below sea level.
The level of certainty over these future effects is close to 100% if we continue to be stupid and do nothing. If we are smart, we need to have a Manhattan–Marshall Plan-like emergency status to a) Zero emissions as soon as possible, i.e. by 2030; b) Cool the Arctic to keep the methane in place and restore jet stream stability, and c) Remove CO2 from the atmosphere/ocean system and remove methane from the atmosphere. There is no other choice.

Paul, thanks again for your incessant work on this incredibly important issue.
You have done a patient and great job of explaining the CO2 issue, brought the barely mentioned methane out of darkness and into our nightmares (and it is a nightmare). However the one that chills my blood is the idea that H2S may be poking its head up in different places in our oceans. Never expected H2S to appear in the climate conversation this early, even in as small amounts as it has.
Are there any measurements of H2S appearances or quantifying its amounts at ocean depths and whether it too is increasing in amounts similar to CO2 and methane? I know they are monitoring ocean temps at different depths, would it be possible (easy, difficult?) to measure H2S concentrations at the same time?
From what I have read so far, the disruption of the oceans currents leads to stratification, which leads to increased deoxygenation of the ocean depths which causes the decomposition of the organic material at depths to change to an anaerobic process which produces H2S.
Scientists are monitoring atmospheric CO2 and methane. Is ANYONE monitoring H2S levels, depths, and locations? Would it be wise to do so, or am I overreacting to H2S’s potential to cause problems?
thanks, dangerous times ahead, sad for our children and grandchildren
There is no question now that we are in advanced abrupt climate change reiterated by Dr James Hansen’s latest paper and the admission by NZ Nobel Peace Prize laureate Dr Jim Salinger who conceded to Robin Westenra and myself that abrupt climate change is underway.
More excellent work from the indefatigable Paul Beckwith and Boomer Warrior.
Kevin – thank you for your response and comments. Welcome to BoomerWarrior.
Paul Beckwith and I are both from the Ottawa region in Canada. We collaborate our climate action when appropriate.
I admit to not having visited the Seemorerocks blog before – so thanks for the link you provided. I like the content and would consider cross-posting some material in the future.
Reflectors in orbit may be the only way to prevent a disaster, but that will take political will and the way to help us get that is in small local groups this gets our voice into the ear of the local member running for office. Now people are starting to wake up and join saveNaturefree.org local groups. see the issues page and the solutions page.
Thank you for your response and for following BoomerWarrior.
The use of geoengineering technology, artificial cloud formation, reflectors, etc. will become necessary if nations do not take the necessary actions to curb greenhouse gases and move to a zero-carbon world economy by 2050. The Paris Agreement was just a wake-up call. Now it’s up to the 195 signatories to the agreement to meet and exceed their stated targets. The Paris emissions targets will still get us to 3-4C of warming. Clearly targets must be ratcheted up very aggressively starting with the 2020 re-visiting of the Agreement.
