Another spring (I guess) in the era of chaotic climate

my Edmonton yard, April 23

Another spring.  I guess.  In the era of chaotic climate.  My last blog post was April 16 of last year, with a comment two weeks later on the McMurray fire.  I talked about dandelions, and wild blue violets, then about my concerns for a dry summer. This year....I'm looking at a sodden blanket of very wet spring snow.  For the third time in April, a couple of warm days and the snow finally off....followed by grey, drizzle, rain and sleet and finally a new blanket of wet snow covering everything.  In February the weather was lovely- +12 or so, the snow melting fast, sunny.  Then March brought a return to snow/thaw cycles.  Oscillations of temperature and precipitation.  The manitoba maples are poised to open their flowers...but keep getting snowed on.  The aspens tassled already several weeks ago, and the hazel flowers, tiny crimson fringed stars, were already opening.  Now LONG grey and white days.  It is nearly May Day, but no green is to be seen around the fresh blanket of white. The past few years have seemed to feature rapid temperature oscillations throughout the entire year.  Literally, if you don't like the weather, wait a minute.  Core-less winters and summers both.  What seems evident in lived experience is the utter lack of predictability.  This winter, and last, cross-country skiing was poor, sporadically available.  New snow followed by a melt and thaw, then cold temperatures with no snow.  You can't ski on ice.  In February it literally felt like spring this winter and last.  February, traditionally the heart of winter in this northern prairie climate.  This year we had snow on Thanksgiving (early October in Canada) but then barely had snow for Christmas.
The lack of predictability, of melts and hard freezes, has ramifications.  In the North, caribou (and reindeer) have trouble feeding when a midwinter followed by a hard freeze created a layer of ice they can't paw through to find lichens.  River ice, crucial for winter transport in the Canadian north, freezes late and has to be artificially thickened to enable motorized transportation across rivers, as crossing the Dempster Highway at Tsiigehtchic.  Warmer climate can cause heavier snowfalls in some places as well, as warmer air holds more moisture than cold.  Plants can flower too soon, fooled by anomalously warm weather, and then young fruit can freeze in later cold.  Chronic stress can cause trees and shrubs to be more susceptible to fungi and to insect attack.  Pathogenic fungi, and insect pests may increase their range, no longer being killed off by prolonged winter cold snaps.  This is the mountain pine beetle story, pushing widespread change in forest composition across British Columbia and elsewhere in the mountain west. 
It's never as simple as "climatic warming". We experience shifts in weather, and in frequency of different weather events.  On a recent trip to the US, I noted that weather reports featured maps showing occurance of "extreme weather".  This was new for me....but not really surprising, as the "atmospheric rivers" are bringing massive amounts of rain, and flooding, to definitively end California's multi-year severe drought. Rainfall and flooding have reached records in some areas not surpassed in the period of recordkeeping
But climate warming, the aggregate of all of the intensified fluctuations, does drive larger changes, melting of permafrost, increasing aridity, changes in range distributions of everything from algae to trees, and of animals species as well. Pacific salmon are appearing in the Arctic, running up the Mackenzie system at the same time as sockeye numbers are diminishing in Oregon, Washington, and British Columbia.  Probably small rises in mid Ocean temperatures, and in the temperature of the Bering Sea and Arctic Ocean are responsible.
Yesterday was Earth Day. Blessings to our planet and may it continue to sustain (and tolerate ??) us.  Yesterday thousands of scientists and concerned citizens marched for the defense of science, which has been under attack by the climate-denying regime in Washington.  I never imagined I would read of thousands and thousands of scientists and supporters marching [having to march] to underscore the value of science to humanity, to bring the necessity of good science to the public....in part because key segments of the US do not want the inconvenience of having to make significant changes to limit the impacts of our species, and [try to] retain the state of the planet in a pattern that can sustain our own well-being. They would prefer to deny that human action, that business-as-usual, could be causing serious, and likely irreversible, changes to global climate. 
The short-sightedness of the President's pro-coal efforts, at the point when coal use is already declining world-wide, is a small piece of evidence of the self-defeating and unwise courses of action prompted by short-term economic perspectives in reaction to the challenges of actually dealing with ameliorating climate change.  I have deep sympathy for the dislocation of traditional ways of life and can understand the frustration of those from coal mining regions. But a more pro-active response through economic diversification would be a better response than to promote a short lived extension of coal economy, with the inevitable impacts of these last paroxysms of mining on these already much altered landscapes.
We are in uncharted waters.  Our numbers, and our impacts on our home planet are unprecedented.  People argue that our influence on Earth processes is so great that we are actually in a new geologic epoch, the Anthroposcene. (My ex-husband, in a moment of disparagement some twenty two years agocalled it the Obscene some twenty years ago). Climate change and other forms environmental change proceed at global scales. The chemistry of both oceans and atmosphere are changing in response to our activities. We also live in an age of unprecedented communication and interconnection.  People form virtual communities of continental, or even global reach. New modes of communication offer hope as well as threat as we can find those of like mind all over the world, and can promote our diverse messages far beyond the reach of our individual communities.  Chillingly, they can also create echo chambers so we hear only the voices of those with whom we agree, thus polarizing our very senses of reality.  Alt facts are lies.... but depending on where you stand, which is the "alt"? Does truth even exist in a "post-truth century"?  I would argue yes it does. Events like the Oroville Dam flood in California a few weeks ago did happen, even while their causes might be argued.  The March for Science speaks to the necessity of knowing as much as we can, in a dispassionate way, to try to make good decisions for our collective future.

Raining

Raining.  The whole day cool and grey, welcome blessed rain soaking the parched ground.  After the heat and dry, cool and wet.  Made channa curry tonight....made me think back to days long ago, living in a little bush cabin, cooking our dried garbanzos with spices and our home-canned tomatoes, gathering 'wild ginger' root (Asarum caudatum) to use in place of the store-bought ginger we didn't have.  Washed down with home-made green tomato chutney.  Nice to be home, quiet, in the house.  A moment's solitude.  Tonight I used store-bought ginger from my local natural food store, and a garam masala that I bought rather than mixed myself.  And I made a wonderful eggplant curry with little Indian eggplants I bought down in "Little India" in Millwoods, the Indo-Canadian community at the southeast corner of Edmonton.  I was trying to replicate something I've recently had at an Indian restaurant buffet....first time I've seen these little egg-shaped eggplants for sale....so I had to try some.  I had to interpolate between my friend Sigrid Shepard's recipe, one I found on the web, and my memory of the dish I'd eaten; none of the recipes did quite what I wanted.  However I worked it out, the result was delicious, and will serve for tomorrow's lunch as well.
Glad as I am the rains have come, this unnaturally early year still speaks strongly to global climate change.  Apparently this year is on the way to being the warmest on record.  I've read that in fact this is the 11th month in a row that is a record warm year planet wide.  No surprise that the boreal forest around Fort McMurray has burned- more than 450,000hectares to date.  Yesterday, before it began to rain, the wind shifted and the smoke was so thick it was as nearly as bad as I experienced 10 m from a major forest fire near Tsiigehtchic in August of 1999.  And that fire was 12 km from where I was.  This- hundreds.  Air quality went from three to 7 to 10 (top of the scale) in a few hours here in Edmonton.  Then the forcast rain began to fall.  We've had no rain of consequence til now in more than a month.  The soil surface yesterday was dry as powder walking in the ravine.  Dust bowl days come again.
Tipping points.  My ex used to call the current time period the Ob-scene (coming after the Holocene, completely recent, the time after the ice left in the Pleistocene).  It is now fashionable to call this the Anthropocene.  I dragged my feet a bit on the new term....but the more I think about accelerating species extinctions, ocean acidification, being poised to loose the whole suite of Arctic fauna, an entire ecosystem, with the probable complete loss of permanent sea ice.....much more than the iconic Polar bear....3/4 of the Great Barrier Reef in Australia suffering substantial coral bleaching.....and I think, hmm.  Yes this kind of faunal overturn, changes in ocean chemistry, temperature shifts....yes they do seem to rival big dramatic changes in Earth History, in the paleaontological record.
And I've read that this year is already 1.5 °C above the long term mean of the 20th century....Paris sets us to try to limit change to that level over the next 65 years.....a strong El Niño, yes.  But something beyond.  Anthropogenic, yes.  So the Anthropocene is here. And we are all complicit, caught in a way of life that requires gulping energy to subsidize everything about our current globally connected urbanized lives.  Whether we drive a hybrid or put solar panels on our roof, or poo-poo the whole thing and use our wealth to maintain our current comforts,  we are all complicit.  And having caught this iconic tiger by the toe....how then do we, can we, let go?  Where do we fit all of our other values against this one BIG problem?  Future discounting is so characteristic of our species, and so tempting....putting off the problem for the grandchildren to cope with, or at least until tomorrow, or next year, or....
I live in what passes for a heritage house in Edmonton, 95 years old, made of beautiful clear timber from BC's lower mainland.  I honour my house, and the lives of the trees it took to make it.  I honour its history.  But where then do I fit energy efficiency?  Because of the cold weather today, I have the (gas powered) heat on, in late May....the walls are insulated with sawdust; there are some voids at the top of the walls, as the sawdust has settled with time.  Should I be ripping up my walls to insulate more heavily?  I work at home, so the commute doesn't consume energy (I walk across the hall), but I do travel for work, conferences, research....and put 5 to 10,000 km per year on vehicles for that purpose, and several lengthy air flights.  I also do not ride my bike for errands all through the winter, but use my car....so we are all complicit.
As the day slowly darkens into night, I wonder what will happen with the Alberta economy in the wake of both an oil price down-turn and the destruction of infrastructure and homes in the vicinity of Fort McMurray?  Sobering choices.  At least the rain may the fires and check their explosive growth.  For now. And there were several other large fires in Northern Alberta, and elsewhere, this unnaturally early spring which have sparked (so to speak) more evacuations.
