Here’s a discovery by an international team of scientists that’s given me serious pause. Being an alarmist doesn’t solve problems. And ignoring “potential problems” certainly doesn’t solve them … if they prove to be real. But preventive medicine has consistently proven to be worthwhile.

‘This is truly terrifying’:
Scientists discover ocean waters ‘boiling with methane’ in Arctic
October 10, 2019
Scientists studying the consequences of methane emissions from underwater permafrost in the Arctic Ocean announced this week that they found a 50-square-foot area of the East Siberian Sea “boiling with methane bubbles.”
“This is the most powerful seep I
have ever been able to observe,”
lead scientist Igor Semiletov said Monday, using a term for methane gas bubbling up from the seafloor to the surface.
“No one has ever recorded anything similar.”
Semiletov, a Russian researcher who has participated in 45 Arctic expeditions, set out on the Academic Mstislav Keldysh last month, accompanied by scientists from the United Kingdom, the United States, Italy, the Netherlands, and Sweden.
Their discovery was announced in a statement from Russia’s Tomsk Polytechnic University, where Semiletov is a professor. The researchers’ findings from the expedition and Semiletov’s remarks were translated and reported on Tuesday by The Telegraph.
Permafrost is a mix of soil, rocks, and sand bound together by ice that stays frozen for two or more years straight. As human activity causes global temperatures to rise, the world’s permafrost is thawing —releasing ancient bacteria and viruses as well as greenhouse gases such as carbon dioxide and methane that further heat the planet.
Compared with carbon dioxide, methane has a shorter lifetime in the atmosphere but is better at trapping radiation, so methane’s impact is more than 25 times greater than that of carbon dioxide over a 100-year period, according to the U.S. Environmental Protection Agency.
Experts are increasingly concerned about the consequences of thawing permafrost that is located both beneath land and water in the planet’s coldest regions. Last week, the Washington Post reported on “stunning and dramatic” scenes from a region of Eastern Siberia where “sections of many older, wooden buildings already sag toward the ground —rendered uninhabitable by the unevenly thawing earth,” and “rivers are rising and running faster,” sweeping away entire neighborhoods.
The Academic Mstislav Keldysh expedition’s research team, led by Semiletov, traveled to an area of the Arctic Ocean known for methane “fountains” to study the effects of permafrost thawing. Around the “powerful” fountain they found east of Bennett Island, the concentration of methane in the atmosphere was more than nine times higher than the global average.
Describing the researchers’ discovery of the fountain based on the university’s statement, The Telegraph reported:
When researchers drew near to the “emerald-colored” water of the methane fountain, they “could see how gas was rising to the surface from the black depths of the sea in thousands of bubbly strands,” according to expedition member Sergei Nikiforov.
They took samples of bottom sediments, water, and gas, scooping up the extraordinarily large methane bubbles in buckets rather than small plastic capsules and filling several pressurized canisters.
The next day, the expedition stumbled upon another giant seep of roughly the same size, even though discovering seeps among rough ocean waves is usually “harder than finding a needle in a haystack,” Mr. Nikiforov said.
The expedition’s findings, also reported on Tuesday by Newsweek, elicited alarmed reactions from readers and climate activists the world over:
Our seas are starting to ‘boil’ —
with methane. This is not normal.
A New Zealand chapter of the Extinction Rebellion movement — which launched a fresh wave of peaceful acts of civil disobedience around the world on Monday to demand bolder climate policies — tweeted in response to the expedition’s discovery, “This is why the disruption we caused is very minor in comparison to what’s coming.”
“This is truly terrifying,”
… tweeted Jim Walsh, an energy policy analyst at the U.S.-based group Food & Water Watch, linking to Newsweek’s report. Noting scientists’ concerns about permafrost thaw reaching a tipping point, he added that …
“We can’t get off fossil fuels fast enough.”

In the old movie, “The African Queen,” Humphrey Bogart kept warning his passenger, Kathryn Hepburn, that they were nearing a giant waterfall, around one of the bends in the river. As she could neither see the waterfall nor hear any roaring sound of water, she was adamant they continue. As they had no satellite map, and relied only on Bogart’s recollection, they continued on. Sure enough, around a bend was that waterfall. The river flow was too strong for them to get to the shore; they were going over the waterfall.
In true Hollywood fashion, their boat bounced all over, but survived the waterfall. Hepburn was actually exhilarated by the experience. But …
They could have been killed.
If they had taken precaution and gone to the shore just before each bend of the river, they would have seen the waterfall and could have taken preventive measures to ensure their survival with only a slight delay in their river trip.
Similarly, we have many scientists recording serious problems that could pose a threat to our ability to survive on Earth. We also have “climate change deniers” who don’t believe we have a serious problem.
We can dismiss both sides as being inaccurate, as we don’t have “satellite maps of the river.” But the preventive medicine question is:
What would it cost us if we do
act on the assumption that we’re
headed for danger and we later
find that there was no waterfall?
The least expensive form of power generation is photovoltaic. So if we power our homes and cars with PV-generated electricity, we’ll pay less money – both for the power and for maintenance.
There’s no downside!
Recently, millions of students conducted mass protests, concerned about the growing evidence of climate change, and the problems it poses for humanity. One protester sign said:
“The greatest threat to our planet is
the belief that someone else will save it.”
Our political systems – from all parties and with several decades of warnings about the problem – have demonstrated their inability to solve the problem. That leaves it up to us, individually, to make necessary changes. Reiterating energy policy analyst Jim Walsh’s conclusion:
“We can’t get off fossil fuels fast enough.”
My home and car are all PV powered. My only utility bill is Verizon. And I’m living in a healthier, more beautiful environment than I’ve ever been in before. It’s time for all of us to “suck it up” and make the changes we need to make.
That waterfall may be around the next bend.
