“An exclamation point on global warming”: Climate scientists warn 2024 was marked by broken records
The year 2024 is on track to be the hottest in recorded history, as humanity has officially exceeded the 1.5º C threshold established by the 2015 Paris climate accord. Dr. Peter Kalmus, a NASA climate scientist who emphasized his opinions are his own, noted that heating is accelerating “and is now substantially more rapid than it was a decade ago.” Dr. Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science's Department of Global Ecology, observed that from the perspective of scientists who dedicate their careers to studying climate systems, one major question is whether the current temperature spikes occurred because the previous El Niño cycle gave humanity years of relative relief from temperature increases. As such, 2024’s distinction as the warmest year in human history “underscores the reality that the planet will continue to warm as long as we burn fossil fuels and add carbon pollution to the atmosphere,” Dr. Michael E. Mann, a climatologist from the University of Pennsylvania, told Salon. “This underscores the profound impact that human-caused climate change is already having in the form of devastating extreme weather events that threaten our economy and, increasingly, our lives,” Mann said. “On the politics side, the big question is what Trump and the MAGA gang will do to Biden's legislative achievements in the climate arena,” Caldeira said, referring to President Joe Biden’s various executive and legislative reforms intended to address climate change.
