"A new investigation of Elon #Musk’s X by Sky News found that every account set up by reporters, 'no matter their political orientation, was fed a glut of rightwing content', much of which was extreme. The experts it consulted believe this pattern could have resulted only from an algorithm engineered for this purpose, and that 'an algorithmic bias must be decided by senior people at …

Dark forces are preventing us fighting the climate crisis – by taking knowledge hostage
The fundamental problem is this: that most of the means of communication are owned or influenced by the very rich, says Guardian columnist George Monbiot

Tropical islands are turning their biggest challenge into their greatest strength.
Vulnerable to climate change and dependent on expensive fossil fuels, island nations are proving that carbon neutrality by 2050 is economically viable. Solar PV is leading the charge, with innovative Solar-to-X tech converting sunshine into e-fuels and e-chemicals to power hard-to-decarbonize sectors.

Small islands, big impact: the role of solar PV for the tropics
Low-cost renewables provide an opportunity for tropical islands to drive a sustainable, secure and self-sufficient economy. Solar PV emerges as the bulk energy provider, driven by excellent resource conditions and fast-improving economic attractiveness. The anticipated momentum of solar PV in tropical islands can best be characterised as a Solar-to-X Economy.

🌍 The climate crisis demands urgent action. But which actions are best?
Decision makers face tough trade-offs:
Policy A lowers emissions at home but increases reliance on imports.
Policy B cuts emissions long-term but raises unemployment short-term.
Policy C boosts jobs now but increases emissions in the near term.
None of these choices are simple. A policy that looks good locally may increase global emissions, or its effects may depend on what other countries d…

Figure 1: The input space (control space, search space) is a rectangular area Y (the Cartesian product of the input intervals) and it is assumed that any solution is inside this rectangle. In general it is a hyper-rectangle in an n-dimensional control space, but here n = 2. The output space (objective space) is a collection of real numbers X = R". The black-box function f : Y β€”> X can be seen as n single-objective functions f_i : Y β€”> R. The points (a, b, . .., e) are examples of (pairs of) con…
Figure 2: The curves in the objective space here illustrate the idealised point cloud: each curve keeps y1 or y2 fixed and varies the other control continuously. The objective function measures cost (x1) and emissions (x2). The objectives each individually reach zero, but not for the same controls β€” there is a trade-off. The Pareto front is the set of Pareto-optimal points in objective space.
