The global economy could face a 50% loss in GDP between 2070 and 2090, unless immediate policy action on risks posed by the climate crisis is taken. Populations are already impacted by food system shocks, water insecurity, heat stress and infectious diseases. If unchecked, mass mortality, mass displacement, severe economic contraction and conflict become more likely.
Une bonne politique climatique repose sur une bonne science climatique. Et une bonne science climatique repose sur le Groupe d’experts intergouvernemental sur l’évolution du climat (GIEC*) depuis sa création par les gouvernements en 1988. Le GIEC est composé de dizaines de milliers de scientifiques issus de dizaines de pays, qui couvrent les multiples facettes du « pourquoi » et du « comment » du changement climatique. Il établit une ligne consensuelle dans des rapports (*) volumineux publiés tous les cinq ou six ans. Il a si bien rempli cette mission qu’il a reçu en 2007 le prix Nobel de la paix aux côtés de l’ancien vice-président Al Gore.

For years, climate scientists have warned us of rising temperatures, extreme weather, and ecological breakdown. Now, the very people who calculate financial risk—actuaries—are sounding the alarm. Their latest report projects a 50% collapse in global GDP within decades. That’s not a recession. That’s economic devastation on a scale we’ve never seen.

The risk of Planetary Insolvency looms unless we act decisively. Without immediate policy action to change course, catastrophic or extreme impacts are eminently plausible, which could threaten future prosperity.
Global risk management for human prosperity
A new report explores a framework for global climate risk management and includes contributions from an actuary at the Government Actuary's Department.
A new report from U.K. actuaries and climate scientists "shows a 50% GDP contraction between 2070 and 2090 unless an alternative course is chartered," said the lead author.​
he global economy could face 50% loss in gross domestic product (GDP) between 2070 and 2090 from the catastrophic shocks of climate change unless immediate action by political leaders is taken to decarbonise and restore nature, according to a new report The stark warning from risk management experts the Institute and Faculty of Actuaries (IFoA) hugely increases the estimate of risk to global economic wellbeing from climate change impacts such as fires, flooding, droughts, temperature rises and nature breakdown.

Actuaries are calling for more realistic climate risk assessments. This includes the “risk of ruin”: the point past which global society can no longer adapt to climate change. Today’s report from the Institute and Faculty of Actuaries (IFoA) and the University of Exeter – “Climate Scorpion: the sting is in the tail” – puts forward the case for using financial services risk management to evaluate and communicate climate risk. It advocates for “worst-case” scenario thinking around climate change.
