Pine Island Glacier: the latest example of rapidly melting polar ice that will eventually flood major airports

Ecowatch published an informative article about a huge iceberg, roughly 115 square miles, that has calved off of the Pine Island Glacier. The article cites an interesting series of posts by Stef Lhermitte discussing a large new iceberg, designated B-46, which is rapidly disintegrating as it drifts toward the Pacific Ocean.

The series of posts includes a GIF slideshow showing annual sea-ice extent at the Pine Island Glacier. Here is a scrollable PDF showing a series of screencaps taken from the GIF slideshow, with images at roughly a 5-year interval from 1975 to 2018 (depending on what years had available images). The sea ice extent for each year is indicated by a color-coded thick line; over time, this line progresses upward, exposing more of the seawater below. In the background of all images, the satellite image appears to be current, as taken on 10/30/2018.

Overall, this series of images shows a pronounced decline in sea-ice coverage. Within the images, you will also notice that there were a few years, ending in 2013, where sea-ice cover was expanding. Since 2013, the melting/calving has been precipitous. Bear in mind, the polar regions are in total darkness for months each year, and it may take years for new meltwater to mix with the seawater below. Thus, massive ice melting may cause an easily frozen freshwater lens to sit atop the seawater. This will create an illusion of expanding sea-ice extent for a few winters. But, eventually, once the excessive freshwater becomes mixed, or as ambient air temperatures continue to increase, the expanded ice that peaked in 2013 will become just a distant memory.

Putting this in a Geographic Context

Here is an excerpt from Wikipedia, describing this specific glacier:

Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica’s ice loss.[3] The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. It was mapped by the United States Geological Survey (USGS) from surveys and United States Navy (USN) air photos, 1960–66, and named by the Advisory Committee on Antarctic Names (US-ACAN) in association with Pine Island Bay.[1][4]

The area drained by Pine Island Glacier comprises about 10% of the West Antarctic Ice Sheet.[5] Satellite measurements have shown that the Pine Island Glacier Basin has a greater net contribution of ice to the sea than any other ice drainage basin in the world and this has increased due to recent acceleration of the ice stream.

Here are a pair of images, showing Pine Island Glacier’s location on Antarctica, and showing the seas that surround Antarctica, connecting it to the extreme southern oceans.

What Does this Suggest for Our Global Future, and for Aviation?

The rate of calving in recent years is disturbing, and reflects a harsh reality: if our ever-expanding over-consumption of fossil fuels is not reined in, and we continue to see 2- or 3- ppm annual increases in average atmospheric CO2 concentrations (see Keeling Curve), we can expect collapse of these polar glaciers and large-scale sea-rise. Hundreds of the busiest airports across the globe will become underwater. Homes for more than a billion people will also become uninhabitable, under sea-rise. Displaced people will need to find new homes, and that situation will result in global conflict and likely massive human depopulation.

Would it not be a good idea to immediately impose policies that strongly disincentivize excessive and arbitrary use of aviation?

A Closing Image: Accelerated Melting is Likely

Below is a different perspective, rotated, but showing the recession of the glacier (roughly from left to right) and how it compares to actual shorelines beneath. The areas of ice over water are designated as the ‘northern ice shelf’ and ‘southern ice shelf’. Over land, colors appear to show ice flow rates using a spectrum, with red being fast, yellow being moderate, and blue being slow. A major concern among scientists who study polar ice loss and related sea-level rise is that loss of sea-ice eventually removes an important ‘plug’ that holds back glacial ice over land; kind of like eroding the footing out from under a bridge pier. In other words, in this example, the fear is that once the Pine Island Glacier recedes beyond the base of the SW tributary and the southern ice shelf is nearly gone, ice flow from the SW tributary will rapidly accelerate, which in turn will rapidly accelerate global sea-level rise.

It would seem to be very foolish, to continue to ignore this evidence.

‘Stay Grounded’: International Action has Begun, to Curtail Aviation Excesses

Click on the image below for a scrollable view of the international Press Release; the PDF file may be downloaded.

Over the past year, activists from around the world held a series of lengthy teleconferences to craft a position paper,’ 13 Steps for a Just Transport System and for Rapidly Reducing Aviation‘. This is a great group of people, concerned about aviation excesses in the face of unmitigated climate change.

Here are a few links:

  • Action weeks: the first two weeks of October 2018
  • Support: how you can support the Stay Grounded effort
  • Position Paper: download your own PDF copy of an excellent analysis (English version)

An example of recent activism was the protest by Stay Grounded leaders, at an EU aviation summit. Click here for a video, with a great protest speech. This is the kind of calm and factual activism we need across the planet, to rein in the damages and injustices being caused by excessive aviation growth.

Given the depressingly evident impotence and indifference of many U.S. elected officials, and the captured status of FAA as an industry-servant, we need this kind of activism here in the U.S. Can we return to our roots, as strong individuals who speak truth to power and demand meaningful civic involvement, or has this become a relic of our past American glory?

A Short Video by Tyndall Centre

The Tyndall Centre for Climate Change Research created this short video:

The most important fact laid out in the video is that aviation technologies are already highly evolved and, as such, there are no great gains to be achieved with further technological improvements. Thus, impacts need to be addressed by reducing number of flights and total distances flown.

To take real actions to correct this situation, we need to tame the marketing that fools people into thinking aviation is cheap and good for the economy, while obscuring the environmental and social impacts. We also need to change tax laws and aviation fees, to remove incentives for excessive flying and hub concentration.

The smartest moves now are actually quite simple: change the fee and tax structure on aviation, so as to disincentivize aviation consumption. We need to impose a steep carbon tax on all aviation fuels; we need to impose passenger fees that are proportional to distance flown; and, most importantly, the fee and tax revenues need to be spent OUTSIDE of aviation, in other economic sectors.

You can Choose: Fly Less, or Even NOT AT ALL!

One of the best decisions each of us can make, for the environment and the future lives of our children, is to become truly mindful about fossil fuel consumption. Air travel is an incredibly intensive consumption method, and the fastest way each of us can pump fossil fuel emissions into the atmosphere. So, here’s a prominent scientist discussing his decision, more than a decade ago, to stop flying. This could be you, too; and, if you choose this method of showing our concern, you’ll also help reduce other impacts such as the NextGen non-stop streams destroying a few communities across our nation).

So, think about it. Please fly less, or even not at all.

The Congressional Process to Reauthorize FAA: Is it Just a Show, and Will it Go Far Enough?

Lots is happening in DC right now, though it is not clear if more than a few of the well-paid elected officials care enough to press through long-overdue reforms. If they fail to alter FAA’s cozy protectionism of this industry, the problems will persist: more noise (along with less sleep), more air pollutants (along with higher morbidity rates), and more rapid expansion of the greenhouse gas emissions by an industry that is the fastest growing contributor to global climate change. In time, the latter will mean loss of the polar ice (which appears to be accelerating), as indicated in this chart:

selected years added and labeled by aiREFORM (click on image to view source at NSIDC)

Note how Arctic sea ice has steadily declined in the past three decades. Losing polar ice is not a trivial matter; it will result in much higher sea levels, higher atmospheric energy and water vapor levels (stronger winds and bigger rain/snow events), and intensified weather extremes (the kind that fool trees into blooming early, only to freeze off the pollinized blossoms, killing that year’s fruit crop).

The Ball is in Your Court, Congress!

This week, the details are being deliberated in the U.S. House, and it looks like the Senate is also pressing to ‘hurry up’ and reauthorize FAA. Congress has important work to do for us in the U.S., but the consequences are global, going far beyond just us. From a climate justice perspective, the consequences are horribly unjust. Air travel and air cargo are industries that serve the wealthiest nations, but the poorest nations tend to be the most vulnerable. A nation like the U.S. can spend enormous funds elevating runways in Florida, but what is a small nation in equatorial regions to do, except simply move away? And, as the most vulnerable nations are destroyed, the global scarcity of land will only compel more instability, more refugees, and more wars.
We need to understand this now: there are real and ugly consequences for our obsessive hyper-consumption, and aviation is a big part of that bad habit. Every benefit bears a cost; the aviation-related benefits we enjoy today are at a growing cost to others on the planet … not just airport neighbors near over-developed U.S. hubs, but also communities at or near sea-level, across the globe.

Some Resources

Here are a few current documents and articles for readers to ponder:

  • HR.4, FAA Re-Authorization draft, Section-by-Section Summary – offers summaries of the many proposals, before most were either withdrawn or voted out by committee. One wonders: is there a better process for compelling a captured agency to serve THE PEOPLE, not just their industry? Is this current process rigged to empower lobbyists and opportunistic politicians? (27p, click here for archived copy)
  • HR.4, Draft Rule – take a look at the rules set up to ‘manage’ the amendment proposals and ensure the final draft serves industry. (click here for archived copy; click here for source)
  • UPDATE: The Dirtiest of Washington Politics? — ATC Privatization By Deception? – it was suspicious when Shuster suddenly announced abandonment of ATC privatization and his decision to not run again. Now it is back on the plate again, which begs the question: did Shuster et al decide to quit wasting effort deliberating and instead just impose their industry-serving plans?

Elected Leaders Need to Work Together

Most of us are smart and rational people, who understand our growing problem with Climate Change and its connection to fossil fuel consumption. Those of us who apply critical thinking, to reason past the propaganda lines spun by the aviation industry cabal (aviation lobbyists, industry players, faux-regulators, etc.), understand this stark fact:

Aviation relies heavily on fossil fuel consumption, and is the fastest way for each of us to further burden our stressed atmosphere with more carbon emissions.

So, what to do about it? It seems to be a no-brainer. The growing number of responsible elected officials who are speaking up to address climate change … they need to join up with elected officials who are fighting to clean up the health and community impacts by excessive scheduling at the most problematic airports. On both counts, this is a fight for a healthy future, and to minimize the life-shortening consequences of too much fossil fuel consumption. Aviation is the perfect place to start.

New Brochure Debunks Greenwashing

A new brochure has been published by Finance & Trade Watch, an NGO based in Vienna, Austria. Authored by Magdalena Heuwieser, the 24-pages debunk many of the most common forms of aviation greenwashing. The brochure includes lots of interesting insight that will further inform about the state of regulatory capture that applies not just to FAA but also to the international body, ICAO.

We should start educating youngsters early on about the dangers of noise

In a big city, we all expect noise. But, the most responsible among us also expect to do all they can to minimize the impacts and manage how we live with it, so that children can learn, homes can be enjoyed, nature can be heard, and we all can get daily sleep. The importance of sleep to New York City is reflected in the following education module:

BTW, one of the key advocates for ‘noise-management-sanity’ in the NYC area is Dr. Arline Bronzaft. See two of her archived articles, spanning TWO DECADES(!), at these links:

And let’s be careful to never forget: it is not just the noise, but the pollutants, too. The toxins we breathe near airports, as well as the rapidly growing aviation contribution to global warming.

WaPost OpEd: “For the Love of Earth, Stop Traveling”

An opinion piece in the Washington Post lays out the simple answers: air travel consumes far too much energy, creates far too much environmental damage, per person. Good points.

The simple solution is for more of us to voluntarily travel, a lot less. The government would help, a lot, if they would impose a very steep aviation carbon tax, with all revenues going to reducing other personal taxes and/or funding far more energy-efficient transportation modes, to replace the energy-efficiency of aviation.

A Spin-Story by National Geographic?

In the blog ‘Flying Less: Reducing Academia’s Carbon Footprint’, Parke Wilde has written a deep analysis of a recent National Geographic ‘article’. The article, by Eric Rosen, generally looks at how commercial passenger aviation is growing in Asia. Mr. Wilde found parts of the article implausible, especially where aviation was presented as an increasingly ‘green’ industry. So, he researched and wrote a blog post. He also asked National Geographic to explain how they appear to be failing their traditional high journalistic standards; the magazine officials did not reply.

The bottom line on air travel is this: there is nothing else you can do that has a higher carbon impact per hour. The industry and the faux-regulators are working hard to propagandize, but they cannot get away from this harsh reality. Carbon offsetting schemes and alternative fuels are NOT a solution; the are illusion.

If you must travel, minimize it. Each mile you fly translates to a substantial consumption of fossil fuels, and thus a substantial creation of more atmospheric CO2. If your credit cards and the airlines and the mainstream media are trying to convince you to fly more, well, that tells you the best strategy is to fly less.
