How an overheated planet affects the lives of a farmer, a firefighter and a military general

Extreme heat is now becoming far more common – and not just in Singapore but all over the world. In a limited series Surviving the Sizzle, CNA’s The Climate Conversations podcast gets a ring-side view at how the lives of people are changed by soaring temperatures.  ....

"Predicting sub-continental fuel hazard under future climate and rising" by Jinyan Yang, Lina Teckentrup et al.

Bushfire fuel hazard is determined by the type, amount, density and three-dimensional distribution of plant biomass and litter. The fuel hazard represents a biological control on fire danger and may change in the future with plant growth patterns. Rising atmospheric CO2 concentration (Ca) stimulates plant productivity (‘fertilisation effect’) but also alters climate, leading to a ‘climatic effect’. Both effects have impacts on future vegetation and thus fuel hazard. Quantifying these effects is an important component of predicting future fire regimes and evaluating fire management options. Here, we combined a machine learning algorithm that incorporates the power of large fine spatial resolution (i.e. 90 m) datasets with a novel optimality model that accounts for the climatic and fertilisation effects on vegetation cover. We demonstrated the usefulness and practicality of this framework by predicting fuel hazard across the state of Victoria in Australia. We fitted and evaluated ....
