Coming-out

Projections of near-term climate change are a potential research tool. However, for that tool to be most useful, the physical basis for a prediction must be made clear. The basis for our projection of record 2026 global temperature is high climate sensitivity, with its implication that aerosol cooling was still increasing during the period 1970-2005. One consequence, global sea surface warming, already has important effects. Causes of climate change must be understood for policy purposes. Figures in this post and our recent papers are continually updated on our website.[1] We are also now on Substack[2].

Climate Action Tracker

We infer that 2026 is likely to be the warmest year in the period of instrumental data, based on a physics-based approach with identifiable assumptions. This approach may help us learn something in 2026 about the mechanisms of climate change. The figures in this post and our other current papers will be continually updated on our website,2 when they remain relevant. We are also now on Substack3.

There is reason to expect that global temperatures will continue to increase over the remainder of the year, as a strong El Niño event is expected

Comment communiquer quand on ne veut pas passer par Internet ou la 5G ? Les réseaux maillés, ou mesh networks, utilisent les ondes radio pour tisser des chaînes de communication parallèles. Dans des sociétés de plus en plus surveillées où des gouvernements peuvent couper les télécommunications du jour au lendemain, comme en Iran, ces réseaux décentralisés et accessibles ne sont pas qu'un délire de survivalistes. Tracks rencontre les accros au mesh. À Barcelone avec le duo d’activistes Radical Data qui installe partout dans le monde des antennes relais pour le réseau de communication alternatif le plus populaire : le Meshtastic Network. À Londres, où 44 Jackk, un ingénieur électronicien britannique spécialiste des technologies d'espionnage, a créé des tutos pour rendre les alternatives au Wifi accessibles à tous. Et enfin dans la région de Bologne, en Italie, le projet de réseau ultra-local Antennine lancé par Cristina Carnevali donne un accès collectif et partagé à Internet aux habitants là où les infrastru

As reported by the Guardian, scientists just published a warning that Earth is approaching a point of no return. A new study in the journal One Earth shows multiple climate systems — the Greenland ice sheet, the West Antarctic ice sheet, boreal permafrost, the Amazon rainforest — are all much closer to collapse than previously thought. “Research shows that several Earth system components may be closer to destabilising than once believed,” the researchers urged. “While the exact risk is uncertain, it is clear that current climate commitments are insufficient.”
