Der er ikke én eneste klimaaktivist at se til klimatopmødet herude i Paris-forstaden Le Bourget. Ikke så underligt – hele området er spærret af, så der er i det hele taget ikke det store publikum.

Mens mange planlagte demonstrationer er blevet aflyst af sikkerhedsgrunde, er der mange protester i medierne og andre steder, der ivrigt opfordrer deltagerne i klimadrøftelserne til at presse på for en mere drastisk traktat.

Il n'y a aucun activiste en vue ici au Bourget dans la Banlieue de Paris où se déroule actuellement le sommet sur le climat. La zone a été bouclée, ce qui est compréhensible, et l'on y retrouve quasiment pas de public. 

Cependant, bien que les marches préalablement planifiées aient été annulées pour des raisons de sécurité, vous trouverez encore beaucoup de manifestants passionnés qui tentent de faire pression dans les médias et ailleurs sur les intervenants de ce débat climatique en faveur d'un traité plus drastique.

The decision by Facebook founder Mark Zuckerberg and wife Priscilla Chan to use 99% of their Facebook shares to fund charitable initiatives over their lives is an overwhelming statement of generosity. The massive challenge for the Chan Zuckerberg Initiative will be how to achieve the most good with this money.

Individual philanthropists play a vital role in development, not least because – unlike political initiatives or groups dependent on fundraising – billionaires can afford to ignore lobby groups and popular attention.

One of the things we’re hearing more and more about here in Paris is so-called “climate aid.” There has been a huge push from climate NGOs to convince rich countries to spend a fortune to help poor countries adjust to global warming. This term is a catch-all for money being given from rich countries to poorer countries for global warming education, solar panels, adaptation, or anything you can imagine that can be linked to global warming.

There’s a lot of focus now on the politics of Paris. Will poor countries get the "climate aid" they want? Will China agree to reduce its growth, leaving millions more in poverty, by committing to far-reaching carbon cuts? What will be the wording of the treaty that emerges?

It’s easy to become cynical. Let’s instead take a step back and ask a much more interesting question: what would it take for Paris to succeed? By this, I don’t mean that the delegates manage to sign some kind of treaty. I mean, what would it take for Paris to have a real impact on climate change?

Is man-made climate change our biggest problem? Are the wildfires, droughts and hurricanes we see on the news an omen of even worse things to come? The United Nations and many political leaders think so and want to spend trillions of tax dollars to reverse the warming trend. Are they right? Will the enormous cost justify the gain? Economist Bjorn Lomborg, director of the Copenhagen Consensus Center, explains the key issues and reaches some sobering conclusions.

If you don’t learn from history, you’re bound to repeat it. Here in Saint-Denis, northern Paris, a history lesson is sorely needed.

Thousands are gathering here for the 21st international global warming meeting. Hotels are already near-full, broadcasters are setting up, protestors are preparing to roar.

All because this summit is "the last chance" to avert dangerous temperature rises, if we listen to the Earth League or a bunch of others. It’s going to be "too late" if a meaningful treaty isn’t negotiated here in the next few days, says the French president.

Hvis man ikke tager ved lære af historien begår man fortidens fejl. Her i Saint-Denis, det nordlige Paris, er der gevaldigt brug for en historietime.

Tusindvis er samlet til det 21. globale klimatopmøde. Hotellerne er næsten fulde, Tv-stationerne er på pletten og demonstranter varmer stemmerne op. Jeg er selv i Paris for at skrive for i alt 25 aviser verden over inklusive China Daily og Economic Times/Times of India.

Si l'on ne tire pas les leçons de l'histoire, on est forcément amené à la répéter. Ici à Saint-Denis, au nord de Paris, nous avons grandement besoin de tirer des leçons de l'histoire.

Des milliers de personnes sont rassemblées ici pour le 21e sommet international sur le réchauffement climatique. Les hôtels affichent quasiment complet, les médias s'installent, et les manifestants se préparent à déclamer leurs revendications.

En el material oficial para la conferencia sobre el clima de París en diciembre, Bolivia afirma sin rodeos que “para una solución duradera a la crisis climática debemos destruir el capitalismo”. Esto puede ser un punto de vista minoritario, pero está claro que París probablemente traerá aparejados grandes cambios económicos.
