The numbers are in, and they paint a sobering picture: 2024 shattered global heat records, surpassing the 1.5-degree Celsius warming threshold set by the Paris Agreement for the first time in recorded history. While climate data can feel distant, the impacts are hitting home—particularly in North Carolina.
From June 2023 through July 2024, the world endured 14 consecutive months of record-breaking global temperatures. July wasn’t just hot; it was the hottest month in recorded history, likely the warmest in 125,000 years. By year’s end, the United States faced 27 climate disasters costing at least $1 billion each, just one shy of the 2023 record. Hurricane Helene, the deadliest and costliest storm of the year, claimed 219 lives and caused $79.6 billion in damage, much of it in North Carolina.
The primary driver behind these record temperatures is no mystery. “By far, the biggest contributor to record warming is the burning of fossil fuels,” said NASA oceanographer Dr. Ivona Cetinić. While a temporary El Niño and other natural factors added to the heat, they pale comparatively to the impact of greenhouse gas emissions.
“2024 is about three degrees Celsius—or 2.3 degrees Fahrenheit—warmer than the historical global average,” Cetinić said. This relentless warming trend has cascading effects, from stronger hurricanes to intensified rainfall and longer droughts.

North Carolina has felt the sting of these extremes. The state endured unprecedented shifts from drought to torrential rain, culminating in Hurricane Helene’s devastation. Warmer oceans, fueled by climate change, supercharged the storm, leading to historic rainfall, flooding, and loss of life.
“Hurricanes have always been powerful, but now they carry more energy and rainfall because of warmer oceans and increased evaporation,” Cetinić explained.
The implications of crossing the 1.5-degree Celsius threshold are staggering. Scientists warn that sustained warming at this level will lead to more frequent and severe weather events, species loss, rising sea levels, and widespread destruction.
Last year’s global temperature rise isn’t just a warning—it’s a tipping point. For the first time, Earth exceeded the Paris climate pact’s long-term warming limit for an entire year, a dangerous precedent that could worsen if global emissions aren’t curbed.
Cetinić believes it’s not too late to act, but the clock is ticking. “This is the only planet we have,” she said. “If we don’t change our ways, these records will keep breaking, and the consequences will worsen. But we can make a difference—by staying informed and taking action.”
As the Southeast braces for more extreme weather, the choices we make now—individually and collectively—will determine the future of North Carolina and beyond
