Covid-19 vaccines protect children from severe disease. Here is the evidence

“Over and over again, Covid-19 has shown it can cause severe disease in children, disease that is preventable by a safe and effective vaccine,” writes former CDC Director Rochelle Walensky.

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

A line chart titled “Annual CO₂ emissions” shows the global carbon dioxide emissions from fossil fuels and industry from 1950 to 2023. The y-axis represents emissions in billions of tonnes (t), ranging from 0 to 40 billion t. The x-axis covers the years from 1950 to 2023.

The chart presents a steady increase in emissions from approximately 5 billion tonnes in 1950 to over 36 billion tonnes in 2023. Key features include:

A consistent upward trend from 1950 through the early 1970s.

A brief plateau and dip around 1980–1983.

A strong growth trend resuming in the late 1980s.

A sharp increase during the 2000s.

A slight drop around 2008–2009, likely due to the global financial crisis.

A major dip in 2020, attributed to the COVID-19 pandemic.

A rapid rebound in emissions after 2020, continuing the upward trend to a new high in 2023.

A blue line labeled “World” traces these changes over time.

Below the chart, the data source is listed as the Global Carbon Budget (2024), and the graphic is credited to OurWorldInData.org with a Creative Commons license (CC BY). A footnote explains that the data includes emissions from coal, oil, gas, flaring, cement, and steel, but excludes land-use changes such as deforestation.

Good review of evidence.👇

The internet is full of misinformation. That's by design, experts say www.cbc.ca/radio/quirks...

Me: "Our information environment is completely manipulated, and often people don't realize the degree to which that is the case."

We are surrounded by information, and yet, 43 per cent of Canadians feel it's harder to decipher the truth from fiction. Several recent studies look at why the information age is so confusing.

It is genuinely your moral duty, if you’re in the sciences, to violate the terms of your contact and take as much of the research home with you as you can. Today, tomorrow, every day your lab’s still open.

Stop dismissing Trump and his team’s *repeatedly stated plan to annex Canada* by, at the very least, bringing us to our financial knees, as a “negotiating tactic.” Sending people their relative’s fingers in the mail is also a “negotiating tactic. One practiced by criminals, not good neighbours.

If you want to know how concerned to be about climate change, talk to a climate scientist. Very.

If you want to know how concerned to be about the rise of fascism, talk to a historian. The ones I’ve spoken to are as concerned about our time as any other time in the last 100 years.
