A new report explores a framework for global climate risk management and includes contributions from an actuary at the Government Actuary's Department.

Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year left hundreds dead or ill. Official government records put the number of heat-related deaths this year as 110, but public health experts say that number is more likely in the thousands. Poor data collection methods and reporting are stopping the country from getting a more accurate picture of how deadly the heat is. Experts are concerned that it's hindering efforts to better prepare for future heat waves.

Le Brexit, la toute-puissance de la Big Tech, les cryptomonnaies, les fake news et même la hausse des prix du café : tout s’explique par le “quantitative easing”, affirme “The New Statesman”. L’hebdomadaire britannique choisit de faire sa une sur les risques et les limites de cette politique monétaire.

Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989
