Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the “Atlantic Multidecadal Oscillation” (AMO) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extra-tropical North Atlantic that play out on 40-60 year timescales (hence the name). Think of the purported AMO as a much slower relative of the El Niño/Southern Oscillation (ENSO), with a longer timescale of oscillation (multidecadal rather than interannual) and centered in a different region (the North Atlantic rather than the tropical Pacific).
Today, in a research article published in the same journal Science, my colleagues and I have provided what we consider to be the most definitive evidence yet that the AMO doesn’t actually exist...
"There are several lessons in this tale. One is that scientists must always be open to revising past thinking. That is part of the critical scientific process—what the great Carl Sagan referred to as the “self-correcting machinery” of science."

Now we can swim any day in November
Don't wake me, I plan on sleeping in (Now we can swim any day in November) - LYRICS
I wanted to walk through the empty streets
And feel something constant under my feet
But all the news reports
Recommended that I stay indoors
Because the air outside will make
Our cells divide at an alarming rate
Until our shelves simply cannot hold
All our insides in
And that's when we'll explode
And it won't be a pretty sight - LYRICS
Or, will there be war? Like the fallen leaves, we may become silhouettes.
Suddenly, everything has changed.
."There are plenty of signs that climate change will be no exception [to The Shock Doctrine]—that, rather than sparking solutions that have a real chance of preventing catastrophic warming and protecting us from inevitable disasters, the crisis will once again be seized upon to hand over yet more resources to the 1 percent." - Naomi Kline, This Changes Everything: Capitalism vs. the Climate.
The time is now.
(I've watched, "Shawn Of The Dead," a few times lately. Apocalyptic movies remind me of now. But this one especially reminds me of COVID).
This month’s open thread for climate science. As if there wasn’t enough going on, we have still more hurricanes in the Atlantic, temperature records tumbling despite La Niña, Arctic sea ice that doesn’t want to reform, bushfire season kicking off in the Southern Hemisphere while we are barely done with it in the North…
Welcome to the new normal, folks.

BTW - I am interested - not that you would say so now, after this post - but, are there any climate warriors out there who will not be voting for Biden. It's a private matter, but you can say so if you like.
Oct. 15, 2020: Climate change likely drove early human species to extinction, modeling study suggests
Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study combining climate modeling and the fossil record in search of clues to what led to all those earlier extinctions suggests that climate change -- the inability to adapt to either warming or cooling temperatures -- likely played a major role in sealing their fate.

A study suggests that tropical cyclones have been increasing in intensity over the past four decades, consistent with predictions of physical theory and numerical simulations.
Volcanic eruption’s effects on Roman Republic
A massive volcanic eruption in Alaska in 43 BCE coincided with the fall of the Roman Republic and the subsequent rise of the Roman empire.
There's a lot we can learn from Mongolian nomads about how to survive in the years to come, says environmental activist Khulan Batkhuyag. Taking us on a journey through the country's stunning rural landscape, she shows how Mongolian nomads have survived in remote areas for thousands of years by virtue of some truly incredible, earth-friendly, zero-waste innovations. There's wisdom here for all of us on how to live more minimally, sustainably and in harmony with Mother Nature.
Note: There's a great indie, documentary-like movie about modern people living in Mongolia, day-to-day. It is stark, quiet and very human. It recalled to me the connexion between these people and Native Americans. Check it out sometime: The Weeping Camel.
Across the Arctic, the warming climate is melting tens of thousands of years of permafrost, and long-dead megafauna are emerging. People have discovered the intact remains of mammoths, woolly rhinos, wolf puppies, and cave lion cubs in recent years. Archaeologists and paleontologists in many areas are now racing against the clock to excavate and preserve the artifacts and animal remains exposed by melting permafrost and glaciers. The same frozen ground or sheets of ice that hid these objects from view for millennia also preserved them, and once they’re exposed, they rapidly start to decay, taking their secrets with them.
The melting permafrost is also revealing buried animal carcasses that may reintroduce long-slumbering bacteria back into an unprepared world. And as the permafrost melts, it releases more carbon into the atmosphere and accelerates the process of warming that caused the problem in the first place. Finds like the Bolshoy Lyakhovsky bear may actually help ecologists mitigate some of the damage.
[Many of our ancestors knew cave bears (Ursus spelaeus) all too well. At Denisova Cave in Siberia’s Altai Mountains, about 3,600km (2,200 miles) from Bolshoy Lyakhovsky Island, a 2019 study of coprolites (fossil poop) and ancient DNA mixed into the cave sediment found that bears had lived in the cave off and on for around 300,000 years, probably alternating with the Neanderthals, Denisovans, and Homo sapiens who also lived there at various times].
