## Off the Charts

Scientists are alarmed as ocean surface temperatures have continuously set new record-breaking highs over the last month.

According to [data analyzed](<https://climatereanalyzer.org/clim/sst_daily/>) by the University of Maine's Climate Change Institute, daily ocean surface temperatures breached historical record highs since at least 1982 in April.

That means we are in uncharted territory as global warming continues to take its toll with extreme weather events becoming more common by the year — and scientists are clearly shaken by the spiking temperatures.

"This is getting ridiculous," physicist and climate change expert Rober Rohde [tweeted](<https://twitter.com/JensTerhaar/status/1650678419049394176?s=20>). "For the last month \[the daily index\] has been continuously reading higher than in any previous year and still shows no sign of settling."

## All Rise

But others argued such a rise should be expected at this point.

"While it is comforting to see that the models work, it is terrifying, of course, to see climate change happening in real life," [replied](<https://twitter.com/JensTerhaar/status/1650678419049394176?s=20>) Woods Hole Oceanographic Institution biogeochemist Jens Terhaar. "We are in it and it is just the beginning."

It's part of a greater, worrying trend. A [study](<https://essd.copernicus.org/articles/15/1675/2023/>) published last month in the journal *Earth System Science Data* found that our planet accumulated almost as much heat in the past 15 years as it had in the previous 45, a worrying sign that we're in for considerable rises in global temperatures.

Worse yet, we're still not entirely sure why this is even occurring.

"It's not yet well established, why such a rapid change, and such a huge change is happening," Karina Von Schuckmann, the lead author of the study, [told the *BBC*](<https://www.bbc.com/news/science-environment-65339934>).

## Setting New Records

The previous ocean surface temperature record was set in 2016 during an El Niño, [*ScienceAlert* reports](<https://www.sciencealert.com/scientists-are-alarmed-as-sea-surface-temperatures-hit-uncharted-territory>), a weather pattern associated with a warm band of ocean water developing in the Pacific.

This year's El Niño, however, will kick off at a much higher starting point, as [*Axios* points out](<https://www.axios.com/2023/05/01/ocean-temperature-spike-climate>), which means we could see similar climate events accelerating going forward.

"2023 is off to an alarming start, even before El Niño conditions fully develop later this year," Kim Cobb, a climate scientist at Brown University, told *Axios*, adding that "new record will likely be surpassed in a matter of years."

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
