The world is warming. Just look at Larry Fink’s scarf.

The BlackRock Inc. chief executive wore a climate data-themed scarf to his interview with Bloomberg Television this week at the World Economic Forum in Davos, signaling that his newfound commitment to putting sustainability at the center of his strategy extends to his wardrobe.

The Two Degrees Investing Initiative -- a global nonprofit think tank that is developing metrics for long-term climate risk for the financial industry -- took credit for creating Fink’s scarf in a post on LinkedIn on Thursday.

The “warming stripes” on Fink’s scarf are based on a graphic by U.K. climate scientist Ed Hawkins that shows the annual average temperature for the globe from 1850 to 2018. The visualization uses a color scale that shows the temperature for each year, with the blue cool years in the beginning and the hot red years in the past few decades. Eight of the world’s 10 warmest years have occurred since 2010.

Hawkins sells scarves and other “stripes” gear online.

In his annual letter to CEOs this month, Fink said his firm, with $7.4 trillion in assets under management, would prioritize climate change as a “defining factor in companies’ long-term prospects” and that a global climate emergency might upend global business sooner than many expect.
