What story does sea-level really tell? — I’ve written and made movies about sea level. Here’s a short one: Anyone who studies climate even a little knows of the last ice age 20k years ago, when sea levels were far lower than today: When there’s a lot of ice at the poles, that ice naturally sucks…

If it exists, how large is it in reality? — Recently, Thomas Shula posted an interesting piece on the greenhouse effect, challenging the standard narrative that CO2 drives climate. He also explains this in a video presentation to Tom Nelson. I’m going to walk through this explanation by starting with the conclusion: The radiation energy that the Earth absorbs from…

Is the greenhouse effect of CO2 too small to measure? Today we look at this recent 2023 paper: Laws of Physics Define the Insignificant Warming of Earth — Journal of Basic and Applied Sciences, 2023; Lightfoot and Ratzer Which I summarize: The authors use real-world data (not models or simulations) to determine that at the tropics, water vapor does virtually all the work of the greenhouse effect, and at the…

The IPCC and NASA predict a drop in outgoing longwave radiation as the earth warms. Let’s investigate. — Understanding the greenhouse effect is hard work. It’s not what Al Gore says it is. I haven’t found a good clear explanation on YouTube, though several people have tried. In the simplest possible terms: greenhouse gases have the ability to raise the surface temperature by raising the height of the…

Was it a lack of CO2? Or was it something else? — Forget about government scientists playing games with data. We have physical proof that temperatures were higher before the Little Ice Age. The Hard Evidence Note: BP means “Before present.” Plant macrofossil evidence for an early onset of the Holocene summer thermal maximum in northernmost Europe — Nature Communications, 2015 The authors of this study show that “quantitative summer-temperature estimates in northern Europe based on macrofossils of aquatic plants are in many cases around…

Glaciers, along with polar bears, are the poster child of anthropogenic climate change. We know polar-bear populations have grown remarkably in the last 30 years. What about glaciers? Glaciers are all supposed to be shrinking. Let’s look at some that stubbornly don’t listen to Al Gore or watch CNN: Hubbard glacier, Alaska Jakobshavn glacier, Greenland …

Waste your time here, with me, and let’s get something done — I interrupt my series on CO2 and climate because I’m thinking about … Artifical Intelligence A short video on how some Stanford students used an open-source AI from Meta and trained it with $600 of time from ChatGPT 3.5 and got amazing results by having one AI train the other. By amazing…

If you take out the El Nino signal, what’s left? — If CO2 is warming the earth, then it MUST cause the El Nino and La Nina events that have been going on for hundreds of thousands of years, because those events are largely responsible for our recent increase in temperatures. Yet most scientists agree that the El Nino phenomenon is…

ChatGPT does high-school physics at the level of a confused teenager — I want ChatGPT to understand climate science, not just repeat the IPCC dogma without thinking. I’ve been trying from different angles. In this episode, I help ChatGPT learn to multiply and add basic units of energy. Here is the transcript, unedited. My questions in subhead style and the final answers…
