US management today, stopping research will not stop thermodynamics and system dynamics, cost of adaptation will be much higher, will create much more migration than sending Musk on Mars and waiting the president reaching end of life.

A warning again, when insurance decide to stop insure the money is lost and this state will have to compensate. After the price increase from tariffs their will be the price to pay to repair. Same people will pay and #ubu will be dead.

Creating uncertainties especially as a partner is not a good move. I’m already looking at the share of my money that goes to the US and looking for a more reliable alternative.

Here is a proposed equivalence glossary with alternative terms that can be used in research applications while maintaining the intended meaning: Original Term Suggested Replacement Climate change Atmospheric variability impact Greenhouse gas emissions Industrial atmospheric outputs Emissions Airborne pollutants Racial equity Socioeconomic opportunity balance Gender identity Individual demographic characteristics Diversity, equity, and inclusion (DEI) Workforce participation and representation Environmental justice Equitable resource distribution Justice40 initiative Federal sustainability investment strategy These replacements aim to retain the intent while avoiding potential restrictions in specific research applications. Let me know if you need further refinements.

Since #trumpthegreat claims to be the standard-bearer of the nation’s values. I read the swiss constitution preamble, going back to my country foundations. To read each time before we vote or we say it will cost too much …
In the name of Almighty God! The Swiss People and the Cantons, mindful of their responsibility towards creation, resolved to renew their alliance so as to strengthen liberty, democracy, independence and peace in a spirit of solidarity and openness towards the world, determined to live together with mutual consideration and respect for their diversity, conscious of their common achievements and their responsibility towards future generations, and in the knowledge that only those who use their freedom remain free, and that the strength of a people is measured by the well-being of its weakest members,

Is our society addict to #fossilfuel ? "Changing for good : the program that explains the six stages of change and teaches you how to free yourself from bad habits" en.wikipedia.org/wiki/Special...
#climateaction : identify the political groups and engage the dialogue of change. #climatechange
The theory of change applied to fossil addiction. State People Acts for change NO Not ready "Deny the problem Realise that some are complaining Resist to change using fears, lies and fake information" "Raise awareness Inform of risk Give feed-back on not changing Do not force to change" READY Contemplation "Recognize the problem Feel contradictions Are ambivalent in motivations Consider not changing as a safe decision" "Create the intention Discuss the problem Show options Explore pro and cons Do not give hints or impose solution" PLAN Preparation "Are ready to take actions Identify small possible steps Agree on success indicators" "Actions: Acceptable, Reachable, Measurable and Efficient Elaborate action plans Define the actors and their role Define goals and quantifiable targets Create motivation" DO Action "Change their behaviors Support the transition measures Receive societal rewards" "Support the transition Give rewards (by groups or peers) Re-inforce motivation No-taboo" KEEP GOING Maintenance "Are confident of the value of the changes Transform new practices into norms Accept no return rules" "Sustain Measure and value success Maintain motivation Create no return rules"

System engineering challenge : choose the technologies, their sizes, system interconnections and operation strategies to satisfy the societal needs: food, services and products with renewable energy resources using sustainability criteria. Each word is important.

This is a copy of my last Twitter Tweet. It was once valuable, but “X-version” has lost that purpose for me. In the spirit of ethics and respect, I share the Swiss Constitution preamble—a reminder of values that should guide us: unity, diversity, and responsibility for future generations.
