Scientists have found that 269 airports are at risk of coastal flooding now. A temperature rise of 2C – consistent with the Paris Agreement – would lead to 100 airports being below mean sea level and 364 airports at risk of flooding. If global mean temperature rise exceeds this then as many as 572 airports will be at risk by 2100, leading to major disruptions without appropriate adaptation.
Mass loss from 2007 to 2017 due to melt-water and crumbling ice aligned almost perfectly with the Intergovernmental Panel for Climate Change’s (IPCC) most extreme forecasts, which see the two ice sheets adding up to 40 centimetres (nearly 16 inches) to global oceans by 2100, they reported in Nature Climate Change. Such an increase would have a devastating impact worldwide, increasing the destructive power of storm surges and exposing coastal regions home to hundreds of millions of people to repeated and severe flooding.
The National Coastal Property Model (NCPM) simulates flood damages resulting from sea level rise and storm surge along the contiguous U.S. coastline. The model also projects local-level investments in a set of adaptation measures under the assumption that these measures will be adopted when benefits exceed the costs over a 30-year period. However, it has been observed that individuals and communities often underinvest in adaptive measures relative to standard cost-benefit assumptions due to financial, psychological, sociopolitical, and technological factors. Riskthinking.ai’s forward-looking scenarios can help individuals and communities better understand- and avoid – the costs of sub-optimal flood risk reduction behavior.
California is burning, a Category 4 hurricane with winds of 150 mph just blasted into the Louisiana coast, and nearly 180,000 are reported dead from a viral outbreak that is just a harbinger of what one scientist calls “a new pandemic era” driven in part by our changing climate and wanton destruction of ecosystems. While there are positive indicators that people are waking up to the growing threat of climate change, a much greater pace and scale of climate action is needed to stave off its worst effects. Riskthinking.ai provides clients with forward-looking scenarios tools that render a deeper understanding of the true cost of climate risk, in order to drive timely decision-making.
Extreme weather fuelled by climate change is on the rise- and so are the associated costs. In the last 40 years, 663 disasters linked to climate change in the United States killed 14,223 people. The total cost: an estimated $1.77 trillion, a bit more than Canada’s Gross National Product in 2018.
The brutal effects of climate change, such as Cyclone Amphan that devastated southwest Bangladesh this past May, are hitting already vulnerable communities the hardest, underscoring the importance of applying an equity lens to climate action.
Planning for the future in coastal communities will mean accounting for rising seas levels, which are bringing water into communities at record rates. Forward-looking scenarios like those developed by Riskthinking.AI can help decision-makers uncover the risks and plan accordingly.
