Opinion: Facing up to the truth about climate change

If we want consumers to accept the judgment of science, we need to return the favour

Those pants look terrible on you. Perhaps you’ve experienced that awkward moment when you try to stop a friend from committing a fashion faux pas. If so, you may have agonized how to word your concerns to avoid offence, while still getting your message across. It’s a potentially volatile moment that perfectly captures how I

A protest sign outside Bakersfield, California in 2015 highlighted the urgency of the drought situation that year. Climate researchers say Arctic warming likely contributed to the severity.

Warmer Arctic linked to weaker vegetation growth in North America

The effects of climate change in the extreme north 
can be felt far away, researchers say

Warmer temperatures in the Arctic are having an unexpected effect elsewhere in North America climate, scientists say. Researchers from Korea’s Pohang University and the South University of Science and Technology of China say their analysis suggests the northernmost regions of the continent may be warming and becoming more productive. But that’s being offset by effects


El Niño conditions are developing in the Pacific

We know La Niña and El Niño both have an effect on weather — but predicting it is still a real challenge

El Niño conditions are developing across the Pacific with an increasing probability that a full-fledged El Niño episode will occur during the second half of 2017. Pacific equatorial winds have slackened since the start of the year and a characteristic tongue of warm water has begun to form stretching from Peru towards the international dateline.

Global warming and manufactured doubt

Debate in peer-reviewed science about human-induced warming has been over for ages

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 Jeff Masters asking permission to use some of the information from his blog in

Jumping off the global warming fence

If we take action now, the worst that happens is we clean up our planet

Over the years, some weather articles I’ve written have provoked or inspired various amounts of comments. What surprised me was the number of emails I received about the top weather events from around the world in 2016. What was surprising, in particular, was that several of the emails accused me of leaning too heavily toward


Forecast: Typical mid-winter weather

Issued December 31, 2016 – Covering the period from January 4 to January 11, 2017

After a fairly active last week of December, it looks as though January will start off on the quiet side. High pressure looks to dominate our weather pattern over the next week or two, with the main storm track expected to stay to our south. A ridge of arctic high pressure is forecast to slowly

No easy answers to greenhouse gas emissions

We’ll all have to be part of the solution or we’ll be part of the problem

The solution to pollution is dilution is an old saying, but unfortunately there is a limit to its truth. For well over a century we have been mining, drilling and burning fossil fuels as if Mother Nature intended us to. One gallon of gas can give the equivalent of 600-man hours of labour. Coal and

Canadian scientist Robert Sandford says there is an urgent need to address and adapt to climate change and its effects on the hydrological cycle.

Western Canada has crossed into an entirely new hydro-climatic cycle, scientist says

Climate change is accelerating hydrology at an even faster pace than earlier thought, making for rapid-fire change

A Canadian scientist says those trying to protect farmland from future floods, and bolster local resilience against other extremes of hydrologic climate change must do so with a sense of urgency. “I hope you’ll see beyond urgency to the emergency we face if we do not act in a timely and effective manner to protect


Wetland expansion due to heavier rainfall seems to be fuelling higher methane emissions, along with agricultural activity.

Floods and farms fuel jump in methane emissions — researchers

Microbial sources of methane emissions are seen as the most likely source and are common to wetlands and farming

A sharp increase in methane, a potent greenhouse gas, in the Earth’s atmosphere since 2007 is the result of higher emissions from biological sources such as rice paddies, cattle and swamps rather than fossil fuels, researchers recently announced. Methane traps heat, contributing to global warming. In 2014 the growth rate of methane in the atmosphere

Ice melts on the Aletsch Glacier in Fiesch, Switzerland, August 12, 2015. One of Europe’s biggest glaciers, the Great Aletsch coils 23 km (14 miles) through the Swiss Alps — and yet this mighty river of ice could almost vanish in the lifetimes of people born today because of climate change.

Climate change could cross key threshold in a decade — scientists

Exceeding global warming targets could mean drastic action is necessary

The planet could pass a key target on world temperature rise in about a decade, prompting accelerating loss of glaciers, steep declines in water availability, worsening land conflicts and deepening poverty, scientists said last week. Last December, 195 nations agreed to try to hold world temperature rise to “well below” 2 C, with an aim of
