Scientists, journalists, environmentalists and others who draw the connection between increasing wildfires and global warming often face a backlash. It’s not climate change; it’s lightning, careless smokers or campers, poor forestry management, industrial activity or sparks from vehicles, bad government… One doesn’t negate the other. Wildfires have many causes, and more than one factor is […]

SCIENCE MATTERS: Hot enough for you?
If you follow climate news (and you should), you’ve likely heard of the global warming “hiatus.” In attempts to keep the world hooked on diminishing reserves of polluting fossil fuels, climate science deniers seized on that phenomenon to claim the warming they once argued didn’t exist stopped. Others took up the false claim out of […]

SCIENCE MATTERS: Cool solutions mean a hothouse planet isn’t inevitable
In the midst of worldwide record heat, devastating wildfires, droughts, refugee crises, and torrential rains and flooding, some particular disturbing headlines have hit the news. “Planet at risk of heading towards irreversible ‘hothouse’ conditions” the CBC announced. Similar headlines appeared in other media outlets. As CBC explained, “Scientists from the Stockholm Resilience Centre, the University […]

SCIENCE MATTERS: Will energy efficiency stall climate disruption?
In the race against the increasingly widespread and devastating consequences of climate change, solutions tend to focus on products and technologies. Renewable energy, electric vehicles, biofuels, carbon capture and storage and geoengineering get much of the attention, in part because they lead us to believe we can continue acting as usual. Those technologies must be […]

SCIENCE MATTERS: We can’t hide from global warming’s consequences
Over the past few months, heat records have broken worldwide. In early July, the temperature in Ouargla, Algeria, reached 51.3 C, the highest ever recorded in Africa! Temperatures in the eastern and southwestern United States and southeastern Canada have also hit record highs. In Montreal, people sweltered under temperatures of 36.6 C, the highest ever […]

SCIENCE MATTERS: Energy efficiency and technology squeeze the carbon bubble
The carbon bubble will burst with or without government action, according to a new study. That will hurt people who invest in fossil fuels. As energy efficiency and renewable energy technologies improve and prices drop, global demand for fossil fuels will decline, “stranding” new fossil fuel ventures—likely before 2035, according to the study in Nature […]

SCIENCE MATTERS: Cutting through polluted public discourse
“We’re not going to get off fossil fuels overnight!” How many times have you heard that? Over the decades I’ve been hearing it, we’ve increased exploration and development, continued to build infrastructure that locks us in to fossil fuels for years to come, increased greenhouse gas emissions and pollution, and failed to conserve energy and […]

SCIENCE MATTERS: Better vehicle standards drive innovation and benefit citizens
Transportation accounts for about a quarter of Canada’s greenhouse gas emissions, making it the second-highest source, slightly behind the oil and gas industry. In the U.S., it’s the largest source of emissions and pollution. Despite continued improvements in personal vehicle fuel standards since 1975, Canada’s transportation emissions grew by 42 percent from 1990 to 2015, […]

Science Matters: Reports emphasize urgent need to reverse biodiversity decline
Our health, well-being, food security, energy and economic progress depend on healthy, diverse nature. Clean water and air are essential to human life and health. Nutrient-rich soils are necessary to grow food. Diversity makes the ecosystems on which human life depends resilient. But, as more than 550 experts from over 100 countries recently warned, “Biodiversity—the […]

SCIENCE MATTERS: Audit exposes Canadian climate failures
Scientists, academics, environmentalists and communicators have urged governments to take the climate crisis seriously for decades. We’ve outlined the overwhelming evidence, generated discussion and offered myriad solutions. We’ve confronted politicians who refuse to accept that a problem exists, or that we can do anything about it if it does. That’s frustrating and disheartening, especially for […]

SCIENCE MATTERS Lessons from Cape Town’s water crisis
Many of us in Canada take water for granted, despite drinking water problems in First Nations communities—the subject of a recent column. World Water Day (March 22) reminds us that as the human population continues to grow, putting greater demand on all resources, and as climate change exacerbates drought in many places, we can’t be […]

SCIENCE MATTERS: Renewable communities produce energy, jobs and hope
Anishinaabe economist and writer Winona LaDuke identifies two types of economies, grounded in different ways of seeing. Speaking in Vancouver recently, she characterized one as an “extreme extractive economy” fed by exploitation of people and nature. The second is a “regenerative economy” based on an understanding of the land and our relationship to it. We […]
