This map, created by the Food and Agriculture Organization of the United Nations, shows the dominant agricultural systems around the world. (The dark-green areas are forests and the grey is desert.)

The complicated calculus of climate change

While Canadian farmers may see a longer growing season, there may be more pests and less rain

Farming and food production will be changed as a result of climate change — but the how is a complicated question. “Agriculture is a unique sector,” University of B.C. Professor Navin Ramankutty said earlier this month during this year’s edition of the Bentley Lecture in Sustainable Agriculture at the University of Alberta. “Agriculture is a […] Read more

A slide is pictured behind members of the United Nations Intergovernmental Panel on Climate Change (IPCC) during a news conference on the Special Report on Climate Change and Land after IPCC's 50th session in Geneva on Aug. 8, 2019.

UN report on livestock and climate change gets lost in translation

Panel of climate change experts say meat production must be sustainable — but few noted that distinction

“Eat less meat” was the phrase of choice for describing a new report from the United Nations’ climate change panel. Those three words appeared in headlines in publications such as Time magazine, the National Post, and the Times of London. But the report itself said something different, said the science director of the Beef Cattle […] Read more


The release of carbon dioxide is increasing in tandem with a wide number of other human activities and there is little evidence that agriculture is a major culprit.

Many sources of greenhouse gases are being ignored

Agriculture is singled out while major contributors receive little or no attention in climate change debate

As the discussion on climate change heats up, I find myself defaulting to facts that may surprise you. Climate change is not a new phenomenon. The definition is basically changes in wind patterns, temperature and precipitation that stretches over several decades. With that definition in mind, climate change has been an ongoing challenge for farmers […] Read more



The groupthink on CO2 levels ignores some basic science

Views will change as atmospheric CO2 continues to rise with little or no significant change in global temperatures

As an agricultural producer, a former science teacher, and someone who is involved in the delivery of agricultural extension, I would like to submit some comments in relation to Daniel Bezte’s article in the Feb. 13 edition, “Articles on climate change provoke some readers“. The article’s title is entirely fitting because articles on climate change […] Read more

This graphic shows the daily low (blue) and high (red) temperature during the last 12 months with the area between them shaded grey. It is superimposed over the corresponding averages (thick lines), and with percentile bands (inner band from 25th to 75th percentile, outer band from 10th to 90th percentile). The bar at the top of the graph is red where both the daily high and low are above average, blue where they are both below average, and white otherwise.

Doubt about global warming isn’t coming from scientists

It’s not hard to create doubt about sound science — 
the tobacco industry proved that years ago

Several years ago, Weather Underground’s co-founder Jeff Masters wrote a blog about the manufactured doubt industry, how and when it was created, and how it now plays into the current global warming or climate change controversy. At the time I emailed Masters asking permission to use some of the information from his blog in an […] Read more


This map shows the total amount of precipitation that fell across the Prairies during January. You can see it was a fairly dry month for most regions, with a large portion of Alberta, Saskatchewan, and western Manitoba seeing less than 60 per cent of average.

Articles on climate change provoke some readers

Like politics and religion, global warming is a polarizing topic —
but it’s one that we should discuss

Over the years, some of my weather articles have provoked or inspired various amounts of comments. What surprised me recently was the number of emails I received about the top weather events from around the world in 2016 — in particular, several from readers who accused me of leaning too heavily towards climate change or […] Read more

Last five years were hottest on record

Morocco/Reuters – The past five years were the hottest on record with mounting evidence that heat waves, floods and rising sea levels are stoked by man-made climate change, the United Nations weather agency said on Tuesday. Some freak weather events would have happened naturally but the World Meteorological Organization (WMO) said greenhouse gas emissions had […] Read more



Man-made warming dates back almost 200 years, study says

Oslo | Reuters — Man-made greenhouse gases began to nudge up the Earth’s temperatures almost 200 years ago, as the Industrial Revolution gathered pace, far earlier than previously thought. Greenhouse gas emissions from industry left their first traces in the temperatures of tropical oceans and the Arctic around 1830, researchers wrote in a recent journal […] Read more
