Alexander MacKay and the speed of climate change
Look at this handsome fellow: |

Why it's Dr. Alexander MacKay, superintendent of education for Nova Scotia's
schools (or so said his students and faculty, a little over 100 years ago). And
they no doubt complained about this scientific taskmaster, for MacKay was a
serious scientist, particularly interested in smallish creatures (e.g. lichens,
particularly, and diatoms): he published on those subjects. He eventually
taught biology, although he favored math and physics earlier in college. And
while he may have focused on his favorite creatures, he forced his students to
study nature much more broadly:
"Can you believe that he's having us carry out our science lessons constantly,
through the observation of nature? He wants us to watch for the first
dandelion, for the first robin; to record the moment when our parents do the
haying.... It's unbearable!"
Each of the little rascals in this photo of a Guysborough, Nova Scotia, school
circa 1900 might have been tasked with carrying out Dr. MacKay's
observations.

Oh MacKay didn't set out to be cruel, but he had bigger fish to
fry. Here's the description of his objectives, as published in the Dictionary
of Canadian Biography: "Concerned about rural depopulation, MacKay
developed rural-science programs that he believed would address the problem by
encouraging children's scientific interest in nature. In addition to providing
training and classroom materials for teachers, he instituted an unusual program
of phenological observation for rural schoolchildren. This scheme required
students to note the first appearance of botanical phenomena during the year
and to provide the information to the teacher, who in turn submitted it along
with the school's attendance register at the end of each year. The Nova Scotia
Museum of Natural History holds MacKay's collection of these phenological
reports from 1898 to 1923, and in the 1990s the observations were of
considerable interest to scientists concerned with climatic change in Canada."
Notice that connection between rural depopulation, which MacKay thought to
combat by encouraging scientific interest in nature. People today would
certainly say "Are you crazy?" Science is not sexy today -- was it then?
But we can sympathize with MacKay: how many students today have lost touch with
nature -- are clued in to their electronics, their iPads, their iPhones, and
have no idea when haying begins, or understand the expression "make hay while
the sun shines"?
"Mackay was very serious about
his observation program. Training was provided to teachers, and meticulous
records were kept. Each teacher was required to submit an annual sheet with
the timing of the over 100 observations. These were tallied into ledgers ... of
which any accountant would be proud. Mackay himself was not simply another
government administrator, but he was a member of the Royal Society of Canada
and published regularly on lichens and his phenological observation network
across Canada."

a nice coverage of Nova Scotia schools -- astonishingly good. Unfortunately
continuous climate records from that time were taken at only five locations. source |

The major irony in MacKay's story is that his contributions to science, which
he imagined were in the areas of lichens and diatoms, may have been even more
important in the science of climate change. Because plants and animals respond
to climate by migrating, we expect that the distributions and timings of
nature's events will change as well. MacKay's extensive catalog of events from
the turn of the 20th century provide a rare opportunity for scientists today to
compare and see how things have changed:

This is "phenology" (in case you were wondering about that word
"phenological" that kept appearing above -- it might have reminded you
of the study of the shapes of peoples' heads -- phrenology -- or some
other study). Phenology is actually "...the study of the
synchronization of developmental states of plants and animals with the
seasons." For example, bees begin to forage at the same time as their
favorite hosts flower. It's no accident, but rather the dance that
evolution has choreographed so well over millions of years. And we are
acting as "agents of uncoordination", messing with Mother Nature's
dance. And, as we used to hear in the Chiffon Margarine commercials,
It's not nice to fool Mother
Nature!
MacKay was aware, however, of the implications of his work. His work
was cited in the Presidential address of the Nova Scotian Institute of
Science of March 14, 1898, recorded in the
Proceedings of the Nova Scotian Institute of Science
that his phenological observations "...may lead to some important
generalizations regarding the relation of organized life to latitude
and other climatic conditions." (p. ii)
Furthermore, in comments that foreshadow his future role in defining
science education in Nova Scotia, the President goes on to say that "[i]f we
would study Nature honestly and effectively we must meet her face to
face. She does not woo by proxy, by text-books, illustrations, or
recitations."
Work of MacKay's own hand, published in 1898. His counties are roughly
organized by latitude, as he suggested above in his comments. MacKay went on to
describe 10 phenochrons for Nova Scotia, which were zones with reasonably
similar onsets of natural phenomena. Today we might call them ecozones. He
put the words phenology and chronology together to create his
phenochrons.

Dr. MacKay was the complete package: a thoughtful and considerate educator, a
diligent and thorough researcher, a leader in the scientific academy, an able
and farsighted administrator, and even a wordsmith. We can only thank our lucky
stars that leaders like Dr. MacKay have enlivened our world, and do what we can
to emulate him.
Links and Notes:
- I was introduced to
Alexander MacKay by the book How We Know What We Know About Our Changing Climate: Scientists and Kids Explore Global Warming (by Lynne Cherry and Gary Braasch), and I am indebted to it for this wonderful example. The book is full of other, beautiful, examples, and provides a superb introductions to the major issues of climate change. It's not just for youngsters!
- Here's an extended
biography of Dr. MacKay. According to this biography -- which includes a lovely photo of MacKay -- his ancestors sailed to Nova Scotia from Scotland on the Harmony of Aberdeen, with their departure described in An Unstoppable Force: The Scottish Exodus to Canada:
The departure of the 1822 group from Cromarty harbour was witnessed by many people: "A vast assemblage of the relatives of these poor emigrants, supposed some thousands, attended to take leave of their friends; and the parting scene was of the most affecting nature, such as to draw tears from the eyes of some of the spectators unconnected with the parties."
It was a tearful departure, but the ending was sweet in the sense that the emibrants acquired large tracts of good farmland in Nova Scotia and soon established thriving Suhterland communities there.

- MacKay was an early and vigorous proponent of "Technical Education", as we can see from his remarks in Leading To Technical Education (pp. 49--): "There is a safe place to begin building up a technical system, and that is from the bottom; so that when the top comes to be placed, there will be an effective foundation for the whole. The first tier of the foundation was the introduction of 'nature study' into the schools. This did not require the introduction of a new book: for the book was the open face of nature.... The second step was taken about ten years ago, when in order to create the sentiment in the public school that skilled manual labor was as worthy in its place as the learned professions, every teacher, female as well as male, was required to take a course of woodwork in our Normal School."
MacKay reminds me very much of Booker T. Washington, founder of the Tuskegee Institute, in Tuskegee, Alabama (as described in his marvelous book Up from Slavery). I based my plan for the CFI campus in Haiti on Washington's ideas.
In a brief professional biography entitled "Alexander H. MacKay, Scial and
Educational Reformer", the author N. M. Sheehan says that "...[t]o have a true
education intellectual content must be provided from which exercises in
reading, writing and arithmetic are drawn." Alexander MacKay sought to make
that happen, but, according to Sheehan, was "...born thirty years too soon."
(Profiles of Canadian Educators, edited by Patterson, Chalmers, and
Friesen).
- MacKay's rather extensive bibliography (up to 1894) is found in the Bibliography of the members of the Royal Society of Canada Bourinot (1894)
- MacKay married a fellow student of the Pictou Academy, Maude Johnstone, daughter of Dr. George M. Johnston (who is mentioned several times in the History of Pictou County). Dr. Johnston was part of a group of citizens responsible for forming the Pictou Literary and Scientific Society. No wonder he was so progressive as to have his daughter in school as of 1861....
- The
velocity of climate change (local
copy) is estimated to be 0.42 km/year globally. That is, you need to be
moving about half a kilometer each year to keep up with your environment. Tell
that to the trees!
But it gets worse: a new study suggests that Spread
of crop pests threatens global food security as Earth warms, and they're
estimated to be marching north at nearly 3 km/year.
- The Alexander MacKay story is told in Impact of climate on changes in the seasonal
timing of life cycle events of eastern Canada from 1901 to 1923, Adam
Fenech, Don MacIver, Heather Auld, and Stu Beal. Chapter four in A. Fenech,

- PlantWatch
Curriculum. Page 57 of the PlantWatch
materials has a case study based on the MacKay data -- unfortunately the
website mentioned is no longer functioning. I have been working diligently to
get it back on-line, and available for those seeking to investigate this
facinating data. I'm in contact with Adam Fenech, author of the
article on MacKay cited above, and hope to re-institute the site one
day. In his capacity as Director of the Climate Research Lab,
University of Prince Edward Island, Prof. Fenech and his colleagues
have created a "climate
diary" for PEI, of the sort MacKay used.
In addition to "PlantWatch", there are WormWatch, IceWatch, and FrogWatch
programs. The Nova
Scotia branch of PlantWatch is coordinated by the Harriet Irving Botanical
Gardens of the Acadia University.
- The Climate Diary, prepared by Fenech and company -- it's a lovely document to help one ID the plants and animals of the MacKay data.
- Plant hardiness zones in
Canada, which outline "...the different zones in Canada where various types of
trees, shrubs and flowers will most likely survive. It is based on the average
climatic conditions of each area. In 1967, Agriculture Canada scientists
created a plant hardiness map using Canadian plant survival data and a wide
range of climatic variables. The 2000 map was jointly created by the Canadian
Forest Service and Agriculture and Agri-Food Canada using the same variables
and more recent 30 year normal climate data (1961-90)." My
plant hardiness picture -- it's interesting to compare the 1967 map with
the 2000 map. Our land has warmed by one zone, based on the map.
- MacKay's school science program was an early example (one of the
earliest, actually, and biggest) of so-called "citizen science" --
when ordinary people contribute primary data to scientists. It is an
astonishingly sensible approach: use many eyes to learn quickly about
our world.
Here's a neat modern day example of citizen-science in climate change
research (of which MacKay's story is perhaps the earliest example: Outdoor
rink climate change project gets hundreds of citizen scientists
(folks track when their ice rinks freeze or melt).
