The most striking scenario was offered in 1925 by the respected climate expert C. E. P. Brooks, who suggested that a slight change of conditions might set off a self-sustaining shift between climate states. Suppose, he said, some random decrease of </span><u style="color: rgb(34, 34, 34); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class=""></u><span style="color: rgb(34, 34, 34); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class="">snow cover</span><u style="color: rgb(34, 34, 34); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class=""></u><span style="color: rgb(34, 34, 34); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class=""> in northern latitudes exposed dark ground. Then the ground would absorb more sunlight, which would warm the air, which would melt still more snow—a vicious feedback cycle. An abrupt and catastrophic rise of tens of degrees was conceivable, Brooks wrote, “perhaps in the course of a single season.”</span><span style="color: rgb(34, 34, 34); font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class=""><a href="https://physicstoday.scitation.org/doi/10.1063/1.1611350#" target="_blank" data-saferedirecturl="https://www.google.com/url?q=https://physicstoday.scitation.org/doi/10.1063/1.1611350%23&source=gmail&ust=1570811378843000&usg=AFQjCNG3DI3Es5UakFQ_9D4geP8nz3_lew" style="color: rgb(200, 84, 75); text-decoration: none; word-break: break-word;" class=""> <span style="line-height: 0; vertical-align: baseline;" class="">2</span> </a></span><div style="color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: small; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);" class=""><div class=""><font face="Lora, serif" class=""><span style="font-size: 20px;" class=""><br class=""></span></font></div><div class=""><a href="https://physicstoday.scitation.org/doi/10.1063/1.1611350" target="_blank" data-saferedirecturl="https://www.google.com/url?q=https://physicstoday.scitation.org/doi/10.1063/1.1611350&source=gmail&ust=1570811378843000&usg=AFQjCNGfWADT4LleJxQ99cZeLBb0UbuuDg" style="color: rgb(17, 85, 204);" class="">https://physicstoday.<wbr class="">scitation.org/doi/10.1063/1.<wbr class="">1611350</a></div><div class=""><br class=""></div></div><div class="">
