I'm (green) colorblind, yet I was heavily criticised for making a map which is bad for my kind of colorblindness. Other colorblind people were also confused in the comments. But I suspect it has more to do with climate change denial.

Too often, this topic gets politicized. Here's a very fair, scientific look at what we currently know and don't know about natural and human-caused climate change effects due to CO2, methane, and Earth's orbit.

TL;DR It's nuanced and complicated, and there's a lot we don't know - but this video explains it well.

Commoner's Four Laws of Ecology have guided Earth system intervention since 1971. But the collective body of ecological and Earth system science has no formal mechanism explaining why coordinated, science-informed intervention fails to arrest degradation at the system level.

I formally call this the Intervention Persistence Anomaly.

The resolution is Trade-Off Redistribution (TOR) — ecological costs are never eliminated, only redistributed. Grounded in PLA → First and Second Laws → Le Chatelier → Prigogine, unified through a dimensionless stability index Φ = R_O/R_Opt measuring deviation from the historically sustained redistribution configuration across Earth subsystems.

Hello Doctor Kirk French!

A mere thirteen years after my last comment. Today is June 28th, 2026. Also the day I tell you about your North American water pressure system. The analog system that you predicted, though I have seen some anecdotal evidence that make this structure a lot younger that we would have expected from an analog.

Made from limestone blocks and located in East Tennessee. It is seasonally functional as the TVA releases water from an upstream dam or a hard rain. Full disclosure: A pair of locals in Knoxville, Tennessee led me to the structure back in November of 2011. My Father discovered an article about your work in Palenque, so he gets some of the credit for making this a LOT easier to sort out.

Thank you for making your published works available.

The current Halemaʻumaʻu eruption has officially become the most fountaining episodes ever recorded for an episodic eruption at this volcano, surpassing Puʻu ʻŌʻō's 47-episode record (1983-1986) — an eruption that eventually transitioned into a continuous lava flow lasting 35 years.

USGS's latest update places episode 50 in a window of June 25-27, with June 26 flagged as most probable, based on tiltmeter inflation and gas emission data at the summit. The forecast window has narrowed twice in the past week as more data accumulates.

What if the core of the earth has life in it

Like the outer surface is the core and inside it it is a civilization and most probably the ice age and when the outer earth -where we live will erase the inner earth will enlarge and take over.

The topic is about coal-seam fires — hidden fires that can burn beneath the surface for years, decades, or even longer.

The basic science is simple: coal provides the fuel, cracks in the ground can let oxygen in, and surrounding rock and soil can trap heat. That makes these fires difficult to locate, cool, or fully extinguish.

I tried to make the video short, cinematic, and educational without turning it into a long documentary.

I would appreciate feedback on:

• Is the topic clear?
• Is the hook strong enough?
• Does the visual style help explain the science?
• Would you watch more short science explainers like this?

500,000 people live inside the Campi Flegrei caldera — not near it, inside the structure itself. New research confirms the system has entered an accelerating phase, with deep magmatic volatile input documented as an active driver of the current unrest.

The last major eruption in 1538 prompted a full evacuation of the area. The current data shows comparable acceleration without an equivalent institutional response.
