Se cumplen 31 años del asesinato de Álvaro Gómez Hurtado, un lider inquebrantable, coherente, sin miedo a la verdad. Un gran opositor al oscuro gobierno de Samper, al narcotráfico y a la enorme corrupción del Estado.
Siempre debemos recordar la verticalidad y la firmeza de las ideas de Álvaro Gómez en tiempo de turbulencias y trivialidades.

Every Danish wind turbine combined: 21.6 TWh in the last 12 months
One nuclear plant in Sweden: 23.3 TWh
And nuclear runs 24/7. Wind doesn't
One big reason Denmark has some of the most expensive electricity in the world
nitter.gq/BjornLomborg/status/21…
Denmark spent decades building nearly 5,000 wind turbines
Together, they produced 21.6 TWh in the last 12 months
One nuclear plant in Sweden made 23.3 TWh
Oh, and nuclear runs 24/7 — wind doesn’t
There's one big reason Denmark has some of the most expensive electricity in the world

The cheap green lie
You are told that solar and wind are cheap
But you need near-100% backup when no sun or wind, paying for two systems
Data for 2025 shows that
cramming in more solar and wind makes electricity overall more and more costly

No hay formación universitaria posible sin lecto-escritura.
Que la situación es crítica, es verdad sabida y dolorosa/ comprobada.
Pero seguimos descrestados con aprendizaje basado en problemas, basado en proyectos, basado en retos…
Entretenidos y distraídos.

No puedo creer que estudiantes quemen su colegio para protestar porque las instalaciones no son buenas, o agredan a los maestros para protestar porque no hay suficientes. Algo no obvio amenaza a la civilización occidental.

Copenhagen climate politicians push elderly in retirement homes onto minimal meat to cut CO₂
Birthday wishes for beef are sometimes rejected “for the CO₂ accounts”
Residents pay for the food but often get organic vegetarian instead of what they want

Guidelines (p.45): max 500g meat/week, max 80g beef/veal/lamb (~one kid’s burger/week)

En France, on a inventé le Concorde.
En 1969, il décollait et atteignait Mach 2 symbole de la grandeur gaullienne, conçu pour défier les Américains.
En 1972, le TGV 001 battait le record mondial à turbine (318 km/h).
En 1981, le TGV électrique reliait Paris à Lyon à 260 km/h. En 2007, il pulvérisait encore le record mondial sur rail : 574,8 km/h.
Dans les années 70, le plan Messmer lançait le plus grand programme nucléaire civil de l’Histoire : 58 réacteurs, jusqu’à 70-80 % de notre électricité, une indépendance énergétique que le monde entier nous enviait.
Dassault, Sud-Aviation, EDF, Framatome, la SNCF : nos ingénieurs étaient les meilleurs. On avait dix à vingt ans d’avance sur presque tout le monde.
Puis 1981, Mitterrand. Nationalisations massives (banques, acier, chimie, électronique, aéronautique). Semaine de 39 heures. Lois Auroux. Charges sociales qui explosent. Syndicats tout-puissants. Fiscalité punitive. Droit du travail rigidifié.
En moins de cinquante ans, le socialisme a transformé un pays d’ingénieurs conquérants en un pays de grèves, de délocalisations et de stagnation relative.
L’industrie est passée d’environ 28 % du PIB à 11 %.
Le Concorde a été abandonné. Notre nucléaire a été presque démantelé pendant des décennies faute de choix politique mortifère.
Ce n’est pas le destin, c’est le prix d’une idéologie qui a préféré redistribuer et réglementer plutôt que construire et innover.
A bon entendeur.

Compelling:
The West’s net-zero policies are handing China a huge strategic advantage
While Western nations close reliable energy and raise costs, China adds wind and solar without giving up coal, oil or gas—then sells us the panels, batteries and other products our mandates require
China’s approach is “add, don’t subtract”: build renewables and nuclear power while continuing to expand fossil fuels. This supplies cheap, dependable energy for Chinese industry. Meanwhile, many Western governments deliberately make their own energy more expensive and become increasingly dependent on Chinese solar panels, batteries, critical minerals and manufacturing.
Western climate organizations scrutinize democracies far more aggressively than China, where independent activism is impossible and access depends on the state.
Climate policy should be judged by its actual effect on global emissions, energy prices, industrial competitiveness and dependence on China—not simply by whether it appears ambitious at home.

Is more recycling always better?
A Japanese study estimated the socially optimal rate—including environmental benefits—at 10%.
Recycle more and you pour ever greater resources into ever smaller gains, leaving society worse off.

1970. Yungay, Peru.
An earthquake triggered a colossal rock-and-ice avalanche from Nevado Huascarán. 50–100 million m³ of material raced ~14.5 km down the mountain and buried Yungay. More than 18,000 people were killed.
Atmospheric CO₂: ~326 ppm.
If a catastrophe like this happened today, climate attribution would immediately dominate the headlines. But catastrophic glacier, rock and debris flows have been occurring in high mountains for centuries... and the geological record at Huascarán shows repeated prehistoric events.
Put the emphasis where it can actually save lives: monitor unstable slopes and glaciers, map hazard zones, build warning systems, improve evacuation plans and make mountain communities more resilient.
We cannot prevent earthquakes or eliminate every mountain hazard by changing atmospheric CO₂. We can get much better at keeping people out of their path.
I’ve spent many weeks doing fieldwork in Tibet, sitting above these enormous, deeply incised Himalayan river systems and seeing firsthand just how geologically active this landscape is.
So spare me the climate-change grift every time a natural disaster strikes.
Catastrophic glacial outburst floods are not new. The 1981 Zhangzangbo GLOF released ~20 million m³ of water and debris into Nepal, with estimated peak discharge approaching 16,000 m³/s. The Himalayas experienced enormous GLOFs long before today's atmospheric CO₂ concentrations.
If it happened naturally in the past, we should expect it to happen naturally again in the future—regardless of atmospheric CO₂.
Turning a horrific loss of life into an immediate climate-change narrative without demonstrating that CO₂ caused this particular event isn't attribution. It's opportunism.
And the people exploiting tragedy to do it are grifters.
