Renewables are a masterclass in learning-by-doing. Each doubling of deployment cuts costs via experience curves: better manufacturing, finance & supply chains.

Result:

Solar now cheapest new power in many regions
Falling battery costs enable flexibility
Electrification gets more attractive

A paper in Nature suggests a quarter of heatwave events from 2000-23 would have been near impossible without anthropogenic climate change. The paper also indicates that major carbon emitters are responsible for around 50% of the increase in intensity of these events. ⚒️ 🧪

Systematic attribution of heatwaves to the emissions of carbon majors - Nature

Climate change made 213 historical heatwaves reported over 2000–2023 more likely and more intense, to which each of the 180 carbon majors (fossil fuel and cement producers) substantially contributed.

This means that half of total warming of the median heatwave can be traced back to 180 carbon majors. Moreover, each of these carbon majors caused between 16 and 53 heatwaves to increase in probability by at least a factor 10 000.
