Climate-related wildfires are once again making headlines as they rage across the northern hemisphere this summer. New IIASA research shows that addressing social and economic vulnerability across countries will be a key factor in mitigating the scale of resulting financial damage and emphasize sustainable development as key to reducing climate-related impacts.

People are more likely to do something good for others when they understand the consequences of their actions and would feel guilty if they made a less prosocial choice. This finding comes from a new international study conducted in 20 countries, which also found that people often avoid guilt by deliberately ignoring the impact of their decisions. Surprisingly, shame about what others might think had little effect on social behaviour.

When it comes to susceptibility to influence on social media, “It’s not just about who you are—it’s about where you are in a network, and who you’re connected to,” said Luca Luceri, a lead scientist at USC’s Information Sciences Institute (ISI). A new study by Luceri and his team finds that the likelihood someone will be influenced online isn’t spread evenly across a social platform. Instead, it clusters.

They call this the Susceptibility Paradox; it’s a pattern in which users’ friends are, on average, more influenceable than the users themselves. And it may help explain how behaviors, trends, and ideas catch on—and why some corners of the internet are more vulnerable to influence than others.

A holistic approach reveals the global spectrum of knowledge on the impact of cumulative heat exposure on young students, according to an article published July 30 in the open-access journal PLOS Climate by Konstantina Vasilakopoulou from the Royal Melbourne Institute of Technology, Australia, and Matthaios Santamouris from the University of New South Wales, Australia. The article aims to shed light on the social and economic inequalities caused within and across countries, the potential adaptive measures to counterbalance the impact of overheating, and forecasts about the cognitive risks associated with future overheating.
