Of the $337 billion in insured losses from disaster events in 2017, $330 billion was caused by natural catastrophes, marking a nearly 90% increase from the previous 10-year average. If 2017 was an annus horribilis for the world and the risk-finance industry, which covered $144 billion of these losses, 2018 is on track to be even worse, since this is the year insurers will directly incur these costs on their balance sheets.

The big picture: Research shows that the world’s cities can expect on average $320 billion in lost economic productivity each year because of climate-related risks — climate change, floods, droughts, wild fires and heat-island effect, among others. Meanwhile, because more than 60% of these direct and indirect costs are not typically covered by insurance, insurers and public finance are in retreat as suppliers of last resort. For example, 60% of FEMA claims in Puerto Rico have been denied. Even against predictable threats like floods, earthquakes and wildfires, the protection gap is massive.

In the U.S., from 1950 to 2000, FEMA recorded an average of 39 natural disasters per year. In the 18 years since, the annual average has climbed by 318% to 124, making a calamitous year like 2017 the new normal. These events, even as single catastrophes, can now be directly correlated to climate change.

The effects are damning to the actuarial models insurers rely on to price risk. Houston, for example, had the biggest rainstorm ever recorded in the U.S. when Hurricane Harvey hit in 2017, and that flooding followed other historic floods there in prior years. Ellicott City, Maryland, no stranger to catastrophic flooding, has had two consecutive 1,000-year floods in as many years. If last year’s fires in California were the deadliest, this year they are the largest in state history. When actuarial math is broken in this manner, people are left high and dry and high finance struggles to overcome its expense ratios, ranging between 30% and 50% for every dollar of risk premium.

What's next: Closing the protection gap is an urgent global priority requiring as much public policy work as innovation in human adaptation and financial resilience. Research shows that a 1% increase in insurance adoption yields a 22% decrease in the share of risk borne by taxpayers, which will help stricken communities get back on their feet faster.

By the numbers: Since hitting its low on March 23, the S&P has risen about 50%, with more than 40 of its members doubling, according to Bloomberg. The $12 trillion dollars of share value that vanished in late March has almost completely returned.

Facing enormous financial pressure and uncertainty around reopenings, media companies are giving up on their years-long building leases for more permanent work-from-home structures. Others are letting employees work remotely for the foreseeable future.

Why it matters: Real estate is often the most expensive asset that media companies own. And for companies that don't own their space, it's often the biggest expense.
