The book, "What has gone wrong with Mitigation?", which has just been released, is a collection of 24 analyses I've written since 2018 on international decision-making and wrangling around climate change.

A team at the California Institute of Technology (Caltech) has reached a new milestone in quantum computing: a functioning system with 6,100 qubits. These are so-called neutral-atom qubits held in place by optical “tweezers.” It is the most extensive and most stable qubit array ever built. For the global quantum community, this is considered a breakthrough: for the first time, scalability is being combined with high accuracy and long coherence.

Instead of winding down coal, oil, and gas as promised, governments around the world are preparing to expand fossil fuel production — a move that scientists warn could blow past global climate goals.

Several years ago, I argued that dehumanization had become an unstoppable force in our societies. Since then, the trend has only accelerated, climbing ever higher on the global index of misery. In the few independent media outlets and free forums that still exist, speculation about this phenomenon continues. Yet these discussions increasingly feel like rearguard battles. More and more media are being absorbed by owners who have no regard for free speech — and sometimes not even for truth itself.

In real-world driving conditions, the CO₂ emissions of plug-in hybrid cars are nearly five times higher than official tests suggest, according to an analysis by the European Environment Agency. Automakers often present plug-in hybrids as a more conventional alternative to fully electric vehicles, as they combine a gasoline or diesel engine with an electric motor and a battery that can be charged from the power grid.

The Trump administration has moved to halt construction on the nearly finished offshore wind farm Revolution Wind off Rhode Island and Connecticut. At the same time, Google President and CIO Ruth Porat is steering the company toward fossil fuels to power its fast-growing AI operations. For Porat, it’s a déjà vu moment: during the financial crisis, she was at Morgan Stanley, deeply tied to the subprime mortgage bets that nearly sank the global economy. Now, critics warn, she risks repeating history — only this time with energy instead of housing.

The European Patent Office (EPO) allowed a patent on bush-type watermelon plants and their fruits as technical inventions. However, the bushy growth of the plants was a random natural occurrence and, according to the patent description, was simply discovered. European law does not allow patenting such plants.

As hydrogen infrastructure is rolled out in the EU, refuelling stations must be distributed according to the same principle in all countries. However, a study from Chalmers University of Technology in Sweden now highlights shortcomings in EU regulations. Using an advanced model, the researchers show that the distribution of refueling stations may be incorrectly dimensioned and lead to losses of tens of millions of euros a year in some countries.

Ship traffic in shallow areas, such as ports, can trigger significant methane emissions simply by passing through the water. The researchers in a study, led by Chalmers University of Technology in Sweden, observed twenty times higher methane emissions in the shipping lane compared to nearby undisturbed areas. Despite the fact that methane is a greenhouse gas that is 27 times as powerful as carbon dioxide, these emissions are often overlooked with today's measurement methods.
