I found this description of how much energy we’re putting into our planet from fossil fuels:
Our addition of the greenhouse gases into the atmosphere is the long lever that can move the world. Between 1970 and 2020, 381±61 zetta joules (10^21 joules) of additional energy was absorbed into the system (i.e. the Earth).
This estimate was prepared using satellite data, which is public source, https://essd.copernicus.org/articles/15/1675/2023/
How much energy is this? It’s roughly 80% of the estimated energy of the Chicxulub impactor. Albeit spread over a significantly longer period of time.
The strongest explosion humanity has ever created is in the order of 10^17 joules, or a hundred quadrillion joules.
We’ve managed to add 1.5 million times that number in this 50 years. We’ve been essentially adding one Tsar Bomba’s worth of energy ((approx 50 megatons)) every fifteen to twenty minutes for the past five decades.
The Chicxulub meteor impact blew away roughly half a continent, and the resulting climate change wiped out all the dinosaurs except for birds. We’re doing the same thing to ourselves, spread out a bit but… that’s a lot of energy to be not thinking about. Yeesh.

And good news from Fix the News:
Major wins for U.S. rape kit reform. In 2016, the Joyful Heart Foundation developed an actionable nationwide campaign to end the backlog of untested rape kits across the United States. As of January 2025, 21 states and Washington D.C. have achieved full rape kit reform, benefitting 163.4 million people. Two recent, big wins occurred in New Jersey and Pennsylvania, which both implemented a rape kit tracking system in 2024. End The Backlog
