The record-breaking heat Earth endured during the summer of 2022 will be repeated without a robust international effort to address climate change, a panel of scientists warned Monday.
Heat-related deaths, wildfires, extreme rainfall, and persistent drought are expected to become increasingly severe as both ocean and atmospheric temperatures continue to rise, the experts said. Even if all greenhouse gas emissions ceased today, Earth will continue to warm for several decades.
Radley Horton, a research professor at Columbia's Lamont-Doherty Earth Observatory, stated that human-induced climate change has caused the global average atmospheric temperature to warm by about 2 degrees in the last several decades. Additionally, Horton said, certain climate models have underestimated just how extreme certain events can be, such as the European heat wave of 2022 and the Pacific Northwest heat wave of 2021.Diana Hernandez, Associate Professor of Sociomedical Sciences at the Columbia Mailman School of Public Health, is researching how certain vulnerabilities, such as medical conditions or access to energy, could be affected by changing climate domestically and internationally.
Sorensen noted that she and colleagues referred to summer as “trauma season” early in her career, even before she focused on the health impacts of climate change. “We used to get inundated with patients ... people coming in with heart attacks and asthma exacerbations.”
