Underestimated climate risks from population ageing

Insurability of Climate Risks

The IPCC 2007 report noted that both the frequency and strength of hurricanes, floods and droughts have increased during the past few years. Thus, climate risk, and more specifically natural catastrophes, are now hardly insurable: losses can be huge (and the actuarial pure premium might even be infinite), diversification through the central limit theorem is not possible because of geographical ...

Population stabilization potential and its benefits underestimated.

The Ageing Population

The process of population ageing that has been occurring in Sweden can be expected to continue during the coming decades, the population pyramid will become increasingly rectangular, and possibly even demonstrate a shrinking base. This will lead to increasing challenges in terms of financing pensions, elderly care and healthcare. These problems will continue for at least the next 30 years with ...

Underestimated risks of recurrent long-range ash dispersal from northern Pacific Arc volcanoes

Widespread ash dispersal poses a significant natural hazard to society, particularly in relation to disruption to aviation. Assessing the extent of the threat of far-travelled ash clouds on flight paths is substantially hindered by an incomplete volcanic history and an underestimation of the potential reach of distant eruptive centres. The risk of extensive ash clouds to aviation is thus poorly...

Health risks, present and future, from global climate change.

There is now no serious scientific debate: human actions are changing the world’s climate, and are set to do so at an increasing rate in coming decades. 2 Urgent action is now required to reduce emissions of carbon dioxide (the dominant long acting greenhouse gas), if global temperature rises are not to exceed 2°C—the International Energy Authority warns that “the door to 2°C is closing.” Indee...
