Climate Departure? Too Soon to Say.


I wrote to Camilo Mora asking if the bizarre severe weather events that whipsawed British Columbia in 2021 evidenced the onset of what he termed "climate departure."

About nine years ago Mora and his team of analysts from his climate lab at the University of Hawaii digested hundreds of research papers on our warming climate to find prescriptive patterns of disruptive climate change. 

As they pored through the analyses and data they concluded Earth was on the cusp of entering a new climate that would be unlike anything known in human history. It would be a departure from human experience.


Climate departure isn't about conditions getting hotter. It is about the absence of cold years. It is a new climate in which every year after departure will be hotter than the hottest year before the shift. No more cold years only steadily hot, extremely hot years.Mora phrased it rather eloquently: "The coldest year in the future will be warmer than the hottest year in the past."

Climate departure will be experienced differently in different regions. The cooler your existing climate the easier it will be to endure. However if you're from a warm/hot climate, it promises to be hellish. Climate departure may devastate agriculture, make working in fields difficult even dangerous, and claim the lives of those that typically succumb in heat waves - the very young and the elderly. 

Among the places identified as the first to experience climate departure are the Caribbean and Central America. That could be upon them in less than five years. What climate change is already inflicting on Central America is well chronicled. Crop failures have triggered famine. Nicaragua is the most recent country to urge its people to find sustenance from the local critters, iguana. Unfortunately it's a stop-gap measure at best. Honduras promoted the iguana diet four or five years earlier. The locals have grown so fond of iguana and especially iguana eggs that the creatures are nearing extinction levels.

We are into the 2020s and strange conditions are upon us only not just in Central America, South Asia or the Middle East. British Columbians can attest to that.  Now, in the midst of northern hemisphere winter, South America and Australia are reeling from the heat.

As for the arrival of climate departure, there'll be years, perhaps a decade or more, before anyone will be taking a victory lap. It's really not the sort of achievement to be celebrated especially giving the stubborn resistance of the political caste. 

I have to say that every day I scratch my head with the number of disasters linked to climate change, and how we still avoid dealing with the problem...like the current congress bill to deal with climate change. even if we deal with all emissions now, it will not be in our lifetime before things get back to normal...this is based on paleontological data when similar times have happened on earth.

All we can do now is wait for nature to confirm or refute the theory of climate departure. By the time the data is collected and analyzed it could be too late to make a difference. On this score Dr. Mora recommends that everyone check out "Don't Look Up" on NetFlix.  That might be his way of saying, "We're so screwed." There will be no discernible reprieve in our lifetimes or the lives of our grandkids even if we eliminate all greenhouse gas emissions today and even that is wishful thinking. 

Hey, I've got an idea. Let's build a pipeline. Yeah. And then we'll put the really dirty, highest-carbon stuff in it - bitumen. And we'll put it in giant ships and send it any place we can find buyers willing to take it.

    And today, Nature published a not yet peer-reviewed study that tends to show Omicron simply evades so-called immunity from vaccines or past Covid infections. Perhaps that's why Fauci said the week before last that everyone's going to get it innthe end - he was warned in advance of the likely findings perhaps. Based on what he said and the actual cases in NS hospitals not caused by catching Omicron there after you're admitted for something else, having been vaccinated to prevent this variant seems about as useful as pissing into the wind. It's why I've severely limited wandering out to grocery shop on a whim, because it was obvious to non-epidemiological me before Xmas that Omicron was infecting just about anyone that happened by. Dr Lisa Barrett of Dalhousie U was warning about staying away from everyone else a month ago, and treating ANYONE you meet as a potential Omicron carrier. Anyone means the vaxxed as well as the unvaxxed.

    The situation to me is more serious than during the original Covid lockdown in Spring 2020. We had no vaccine and the original Covid wasn't as infectious.

    When you say new format, do you mean like today's listing of Google Alerts rather than your usual picked enviro-commentary? I'd say whatever suits you. I'll read it.

      Bill, how are you on other vaccines? Flu, pneumonia, that sort of thing. My doctors (I have a few. It's how you know you've been on Earth too long) advised me to get whatever was available. Since most variants attack the respiratory system, pneumococcal and influenza vaccines were no brainers. As often as not that's when people discover their tetanus vaccination expired decades ago.

      It should be interesting to see, a few months from now, how we've settled in with this new affliction. At some point we're bound to say "screw it" especially if it transitions to endemic.

      We don't hear much about the anti-maskers of late but I wonder how the ordinary Joe will react if masking becomes a permanent part of life.

Up in Smoke. 300 Sq. Mi. of Amazon Rainforest Lost Every Day.

Image
  The Amazon rainforest is disappearing at what should be an alarming rate. 312 sq. mi. or 808 sq. kms. every day. Over the past 30 years humans have destroyed a patch of the Amazon equal in area to the states of Texas and New Mexico . The Amazon – historically a great carbon absorber, since trees take in carbon dioxide and release oxygen – now releases more carbon than it stores, which adds to, rather helps to reduce, our global climate crisis. Deforestation rates decreased slightly from 2004 to 2012. But since then, they’re back on the rise, especially in the past couple of years, since Jair Bolsonaro became president of Brazil. In 2018, as Bolsonaro campaigned as a patriotic man of the people, scientists predicted that once the Amazon lost more than 25% of its tree cover, it would become a drier ecosystem, all because deforestation changes weather patterns (due to how trees respire), which in turn reduces rainfall. Furthermore, as the forest becomes fragmented, areas surrounded...

The Cognoscenti Syndrome

  There is a group of people I think of as the Cognoscenti, people who are well educated, very informed and of rapidly diminishing relevance. Their ranks include writers such as Chris Hedges and Glen Greenwald. These are people who have honed an almost Puritanical value system, readily finding fault in any direction. They are scathing in their attacks on Republicans and Democrats alike to the point where they become nihilists. They don't endorse. They prescribe. This is where they fail. They're unable to advocate for anything that might resonate with the public whose interests they argue are being trammeled. Donald Trump was bad but Joe Biden is scarcely better. This is where their elitism comes in.  74 million may have voted for Trump but, hey, they didn't know any better. The mob that stormed the Capitol. They were just victims of the system venting their frustrations. All the racism, bigotry, xenophobia, misogyny, white nationalism - inevitable side effects of their oppr...

Who Asks "Why?"

Every time there's a conflict between the Israelis and Palestinians, all we hear is 'why?'  Why, as in, whose fault is this? It's easier to affix blame if you can truncate the event. Pick a convenient start date, something recent. In this case we'll make it either the Israeli eviction of Arabs from Jerusalem or the scuffle that took place outside the mosque in response. If those don't work, let's go for Hamas launching unguided rockets into Israel. That's even better because it tags Hamas with the blame. The nice thing about this approach is you can just keep using it. It goes on and on, just as it has for the past half-century since the '67 war. You can even date this whole mess to the beginning of the occupation of the Palestinian territories. The Israelis are said to have called these periodic wars, "mowing the lawn." The idea is that, every now and then, you have to take these Arabs to the woodshed. And then you keep your powder dry unt...
