A failure to act to reduce the impacts of climate change could cost Europe dear in lives lost and economic damage, according to a European Commission study.
Inaction over climate change costs lives. And in the case of European inaction, it is estimated that this could one day cost 200,000 lives a year.
That is the warning in a new European Commission (EC) study, which also says that failing to take the necessary action could burn 8,000 square kilometres of forest, and commit European taxpayers to at least €190 billion (US$259 bn) a year in economic losses.
Flood damage, too, could exceed €10bn a year by 2080, while the number of people affected by droughts could increase sevenfold, and coastal damage from sea level rise could treble.
The study weighs the bleak consequences of inaction. Scientists considered what would happen if the politicians and players on the continent worked with international partners to constrain global warming to a 2°C rise, or alternatively took no action and allowed global temperatures to soar to 3.5°C. They analysed the impact of climate change in agriculture, river floods, coasts, tourism, energy, droughts, forest fires, transport infrastructure and human health.
All involved in the research emphasised that their projections were conservative – that is, they were underestimates – and imagined a planet 60 years from now that was occupied by its present population, at its present state of economic growth. In a more populated, more developed world, the losses would be hugely greater.
The biggest and most obvious cost was to human health: premature death – from heat stress or other climate-related impacts – would account for €120 billion; coastal losses would claim €42 billion and agriculture €18bn. The worst-hit regions would be southern and south central Europe, which would bear 70% of the burden; northern Europe would experience the lowest.
If the world keeps temperature rise to the current international target of 2°C, there will still be huge costs, but the constraint would knock at least €60 billion off the overall bill. It would save lives too, reducing the notional premature death toll by 23,000, and would burn only about 4,000 square kilometres of forest.
Calculations such as these − which are aids to political and economic planners, and intended to spur forthcoming political action − are uncheckable, but they are also almost certainly underestimates. They take no account of losses of, for example, biodiversity, on which it is impossible to place a value, and they do not include the consequences of catastrophic tipping points, such as the melting of Arctic ice.
Connie Hedegaard, the EC’s Commissioner for Climate Action, said: “No action is clearly the most expensive solution of all. Why pay for the damages when we can invest in reducing our climate impacts and becoming a competitive low-carbon economy?

The Uninhabitable Earth: Life After Warming Kindle Edition
It is worse, much worse, than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible. In California, wildfires now rage year-round, destroying thousands of homes. Across the US, “500-year” storms pummel communities month after month, and floods displace tens of millions annually. This is only a preview of the changes to come. And they are coming fast. Without a revolution in how billions of humans conduct their lives, parts of the Earth could become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century. Available On Amazon
The End of Ice: Bearing Witness and Finding Meaning in the Path of Climate Disruption
After nearly a decade overseas as a war reporter, the acclaimed journalist Dahr Jamail returned to America to renew his passion for mountaineering, only to find that the slopes he had once climbed have been irrevocably changed by climate disruption. In response, Jamail embarks on a journey to the geographical front lines of this crisis—from Alaska to Australia’s Great Barrier Reef, via the Amazon rainforest—in order to discover the consequences to nature and to humans of the loss of ice.

Our Earth, Our Species, Our Selves: How to Thrive While Creating a Sustainable World
Our scarcest resource is time. With determination and action, we can implement solutions rather than sit on the sidelines suffering harmful impacts. We deserve, and can have, better health and a cleaner environment, a stable climate, healthy ecosystems, sustainable use of resources, and less need for damage control. We have so much to gain. Through science and stories, Our Earth, Our Species, Our Selves makes the case for hope, optimism, and practical solutions we can take individually and collectively to green our technology, green our economy, strengthen our democracy, and create social equality.
