The
New Year opened with so many questions:
Will
the global economic turmoil become a recession? Will western Canadian oil be
given a stable delivery system to world markets where it can be sold for true
market value? Will the trend to populace politics create more chaos? Will Pinocchio
Trump move from the White House to a U.S. penitentiary?
The
list is lengthy, but the most important question in my mind is what will happen
with the weather. Opinions range from ‘global warming is a China-inspired hoax’
to ‘the world will dry up and blow away within the next 30 years.’
The
best way to find an answer to the weather question is to look for facts. I am
aware that looking for facts is considered old-fashioned these days, but I still
find it helpful.
First,
the World Meteorological Organization (WMO) recently reported that the last
four years of global temperatures have been the hottest on record. Also the 20
warmest years on record all occurred in the last 22 years.
October
just passed was the 406th consecutive month in which global temperatures were above
normal. There is no official final data for November yet, but it appears that
it too will be above average, making it the 407th consecutive month.
That
means that anyone under 33 years old never has experienced a
cooler-than-average month of global temperatures.
So
what’s ahead for 2019 weather? Some scientists are concluding that this year
will be the hottest ever recorded in human history.
The
U.S. Climate Prediction Centre says there is an 80 per cent chance that a
full-fledged El
Niño already has
begun and will last at least until the end of February. El Niño is a weather phenomenon in which
parts of the Pacific Ocean warm and cause weather chaos, including a
warmer-than-usual winter in much of Canada.
The documented
trend to warmer world temperatures combining with an El Niño is the reason why
some science professionals say this year will be the hottest ever.
More
warmth is something the world does not need.
Rising
temperatures have increased droughts, wildfires, and more violent weather in
general. The World Meteorological Organization reports 70 tropical cyclones or
hurricanes during 2018, far above the annual average of 53.
These
violent weather events cause agricultural losses, which are followed by
malnutrition, then large migrations of people seeking more stable living
conditions. These migrations create moral and political quandaries – do you
build walls and pens to keep displaced people off your turf, or do you work to
fix the things causing them to be displaced?
Newspapers
and television news shows have been filled with reports of weather disasters in
recent years. Most of them have been in far off places like Europe, California,
and the U.S. south. But we are seeing weird weather changes – although not as
violent or dramatic - right here at home.
The
past fall and current winter in Haliburton have been among the most bizarre in
memory. There was some precipitation – rain or snow – on 27 of 30 days in November
and 24 of 31 in December.
December
had rain on 10 days, almost double the average for that month.
There
have been eye-popping temperature anomalies as well. Temperatures in November
ranged from minus 26 Celsius to plus 14. December temperatures ranged from
minus 24 to plus nine.
The
wild temperature swings have continued into the New Year. Already this month we
have seen a couple lows in the minus 20s and three or four days above freezing.
Weather
ups and downs are not unusual. We’ve seen them before in the Haliburton-Muskoka
region. However, looking at data from the last 10 years, there is evidence that
our climate is changing.
The
first effects of changing climate are being seen by skiers, snowboarders,
snowmobilers and others who enjoy winter sports.
How
climate change will affect other seasons remains to be seen. The wild winds,
droughts and fires seen in other parts of the world would be a serious threat
to our most important natural resource – our trees.
This
week at a lake just south of Minden I saw a soft maple budding. Budding in
mid-winter is unhealthy and a sign that all is not right in the natural world.
