Climate sensitivity to CO₂: a correction
A revision of a previous estimate of the climate’s sensitivity to atmospheric CO₂ concentrations. It now falls at the lower end of the broad range of 2 to 5 °C cited by the IPCC. Nevertheless, the formula used in the IPCC reports lacks physical consistency.

Climate: has the worst-case scenario been averted?

The interests at stake have become too colossal. Read more
L’écosystème de l’écologisme climatique
Les grandes questions climatiques restent en suspens car seul le temps dira à nos générations futures quelle aura été son évolution réelle. Issu de soucis justifiés ou d’anxiétés suggérées, un écosystème s’est développé autour de ce sujet au cours Read more
Camper sur ses positions climatiques plutôt qu’engager la dispute ?
Le dernier billet de blog de Hans Rentsch, paru sur son site et sur celui de Carnot-Cournot-Netzwerk, reflète très bien la confusion qui est entretenue entre “science” et “politique”, ces deux mots mis en guillemets car la compréhension Read more
La caravane climatique passe par Belém
Une vague de propagande se répand régulièrement, à l’orée des fameuses COP (Conference of the Parties), ces grands raouts convoqués régulièrement et qui assemblent des dizaines de milliers d’inutiles pour convenir de se réunir ailleurs, une prochaine Read more
The improbable carbon neutrality
At the current rate, it would take two centuries for the world to achieve the first phase of decarbonisation decided upon at international conferences and enacted into performative laws. However, 2.6% of global GDP is already invested each year Read more
What climate denialism?
Those who question climate alarmism and its anthropogenic basis find themselves labelled as denialists, however nuanced their remarks may be. This terminology is problematic because it draws an implicit comparison with historical denialism, which stifles any yet necessary debate.
