Critical minerals, which are essential for a range of energy technologies and for the broader economy, have become a major focus in global policy and trade discussions. Price volatility, supply chain bottlenecks and geopolitical concerns make the regular monitoring of their supply and demand extremely vital.

There are four key ways of measuring energy. These metrics capture the transformations and losses that occur across the energy chain. The differences between the first stage (‘primary energy’) and the last (‘useful energy’) can be very large. This means it’s important to be clear about which metric is being referred to when people speak about data on “energy”. In this post I explain these four metrics.

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Le laboratoire travaille sur le projet "Mission 100 jours", un objectif extrêmement ambitieux qui consiste à mettre au point un vaccin contre une nouvelle menace en 100 jours.

Ecosystems rely on interconnectedness — bees pollinate the flowers, predators eats prey, and so on. But these webs, though highly evolved, can be delicate. One link goes missing, and a ripple effect is felt throughout the entire system. As more species are lost, that balance becomes increasingly fragile, sometimes to the point of collapse.

The coasts of Alaska are piled up with dead birds dying of starvation. Experts say that climate change is resulting in shifts in the food chain.

A new Imperial analysis has found that biogas and biomethane, while more climate friendly, leak up to twice as much methane as previously thought. Although biogas and biomethane remain climate-friendlier than non-renewable alternatives, the researchers call for better monitoring and fixing of leaks to ensure biogas and biomethane continue to live up to their green credentials.

Climatenomics lays out how ‘supply chain disruptions’ has become a euphemism for the effects of climate change

By now, you’ve probably heard that global supply chains are in a state of disarray. Here's a simple breakdown of what’s causing it: ...
