i have said this before but if you are actually interested in influencing people beyond a narrow circle of too-online journalists you will be making direct to camera videos on tiktok, instagram and youtube. if you primarily post on text-based social media then you're just dicking around.

👀 New global projections show glacier disappearances peaking 2041–2055, with ~4,000 glaciers lost each year.

Regional impacts vary, but the global signal is stark.

Remember: when a glacier disappears, a landscape disappears with it.

What is the clause of the Constitution that says the founding fathers meant us to have AK-47's but not surface-to-air missiles?

How does the Supreme Court justify such distinctions?

One might think they were talking about well-organized state militias and single-shot flintlock rifles.

I have never thought about this at an Australian university. I cannot imagine the extra stress of school and university educators to think about keeping their students safe from mass shootings. My husband is American. I will never live there until there is gun control. Stay safe US colleagues.
Each semester I go in my classroom and I try to figure out what we would use to block the doors, if it would be safe to crawl out the windows, where we could hide if there was a mass shooter in campus. It’s such an indictment of this country how we have normalized these preventable tragedies.

HOW??????????

"We are very sorry to share that we have confirmed reports of multiple shooting victims, but we are not able to share their condition. They have been transported to local hospitals."
