Someone said, ‘Greed is good’ and we repeated it. But the only thing that matters when you die is your legacy
I have to apologize to the youth of the world for the state we find ourselves in. Yes, great things have happened in my lifetime. We watched the fall of the Berlin Wall and we have taken some steps in the progress of human rights. But the legacy of the baby boomer generation leaves little…
Disturbances by humans or nature change the balance of fungi in soil, potentially making it harder for seedlings to regenerate
Disturbances can hit Alberta’s lodgepole pine forests hard – including life under the soil, new University of Alberta research shows. Fungal communities that nourish pine tree roots are being altered by both human-made and natural disturbances, which can stress forests and make it tougher for pine seedlings to regenerate, said Jean Rodriguez Ramos, a PhD…
U of A scientists urge more monitoring of butterfly populations to help understand alpine environments predicted to change rapidly
Mountains and butterflies are conceptualized as the ultimate juxtaposition – enduring and resolute versus fleeting and delicate – but the surprising robustness of alpine butterflies could help scientists better understand the impact climate change is having on mountains. In an essay written for the third annual State of the Mountains report by the Alpine Club of Canada, University…
Canada depends on imports for fruits and vegetables. We need to think differently about how we feed ourselves during cold months
California is on fire. Although most of the fire-affected territory has nothing to do with agriculture, the smoke is so intense that it could damage many crops. And as fall approaches, the California fires could affect Canada’s food supply for the coming months. Like the labour issues affecting Canadian farmers this summer, this is certainly…
Changing balance of microorganisms in Arctic soil due to climate change could have widespread effects, according to new research
Microbial communities in Arctic permafrost changed drastically at the end of the last ice age – and the shift could happen again due to modern climate change, according to a new study by University of Alberta scientists. The researchers compared the microbial communities found in permafrost formed during the last ice age, at the end of…
The gap between expectations and existing policy is wide. Closing that gap will cost thousands of jobs and devastate whole economic sectors
By Mark Milke and Lennie Kaplan Canadian Energy Centre Aspirations are important in life but it’s always helpful to be clear on the means to the desired end, especially if others are involved. A case in point: General commitments by governments in Canada to significantly reduce carbon emissions by 2030, i.e., the Paris commitment. In…
But a true recovery in oil prices will require an economic recovery, whose timing remains unclear
While there’s certainly carnage and woe in the oil and natural gas sectors at the moment, reports of the death of the industry are exaggerated. Many climate change activists and their sympathizers have been cheered by the dramatic drop in oil prices that coincided with, and were partly caused by, the COVID-19 pandemic. Prominent among…
U of A biologists lead effort to identify lakes, hills and peat lands where species stand a better chance of survival
North America’s boreal forests are warming and drying from climate change. But they still hold places that can offer refuge for plants and animals, according to University of Alberta scientists who have taken the lead in creating a guide to identify those areas. The information about these sheltered places known as climate-change refugia – including…
With climate change, unrelenting rains can be challenging for wildlife and plants
aa Rain is a good thing. It has so many beneficial properties – a source of drinking water for everything, a source of nutrition for plants and micro-organisms, a refreshing relief from the heat, a mechanism to replenish aquifers and lakes, a means to clean overlooked homes and cars, fun for kids of all ages,…
The authors of a letter to Trudeau say most aid should be expedited but for oil companies, which need to be trapped in a bureaucratic nightmare
When professors around the country were busy figuring ways to deliver their classes online, two faculty members at the University of Alberta wrote a letter and enlisted the endorsement of 200-plus of their leisured colleagues at 33 universities in Canada. A crisis must not be wasted. From the privileged positions of publicly-paid jobs, the Alberta…
