Can climate change alter tectonic plate stress by moving huge amounts of mass around the planet, especially by melting ice sheets and glaciers, shifting water into the oceans, and changing loading on faults and volcanic systems? Will this climate change consequence contribute to or accelerate the next big California earthquake, which has been predicted to have a high probability of occurring over the next decade or two?

Climate change is no longer just an environmental issue tucked away in science reports, polite political speeches, or corporate sustainability brochures written by people who have clearly never understood the physics of climate change. It is now a global systems problem affecting food, water, insurance, public health, migration, democracy, coastal property, supply chains, and the long-term livability of whole regions.

Do you know which near-term climate change consequences are already unavoidable, which are still partly avoidable, and what families, property owners, and businesses should do next? Because climate theory gets real the minute it reaches your lungs, your kitchen budget, or your insurance bill.

The greenhouse-gas past is warning us, loudly! This article compares the best credible evidence we have for ancient and recent greenhouse-gas levels, the temperatures that accompanied them, and the awkward lesson modern civilization keeps trying to dodge: Earth has often ended up much warmer when greenhouse-gas levels stayed high long enough.

Back in 2008 and for years afterward, tens of thousands of individuals read Mark Linus's 6° book about the future of climate change. He made many powerful temperature and date forecasts. We decided to check back in 2026 and see how well he was forecasting. Even if you didn't read his original book, the article below, with its current and worst-case forecasts compared to his original forecast, is well worth reading.

Why the World Feels Broken: 15 Interlocking Global Crises Driving the Polycrisis. A definitive guide to the unfolding climate change-amplified global polycrisis from 2026 to 2050, containing the most critical timelines and the detailed steps for how 15 global systems can seriously destabilize our human civilization. It explains why the next few years matter critically --- if we want to preserve a livable future!
