A new study published in ScienceDaily claims severe ocean overheating may be causing a fundamental climate shift. Ocean heatwaves over the past couple of years have been massive and extensive and intensive on a scale never seen before at times covering 96% of the world’s oceans, which should be impossible. (The Oceans are Overheating – and Scientists Say a Climate Tipping Point May be Here, ScienceDaily d/d July 26, 2025)

Starting in 2022-23, massive ocean heatwaves persisted for more than 500 days covering nearly the entire globe. This shocking event, never witnessed before, puts the entire global warming scenario on a new level that’s predictably negative. The message is as clear as a bell: World leadership should focus on removal of fossil fuel emissions as soon as possible. Global warming, especially in the ocean, is on a rapid upswing and not waiting around, as such, fully 2/3rds of the planet is suffering a very dangerous heat stroke that’s separate and apart from extreme heatwaves on land.

After all, Earth is basically a liquid planet, according to NASA: “Covering more than 70% of Earth’s surface, our global ocean has a very high heat capacity. It has absorbed 90% of the warming that has occurred in recent decades due to increasing greenhouse gases, and the top few meters of the ocean store as much heat as Earth’s entire atmosphere.” (Ocean Warming/ Vital Signs, NASA)

Scientists fear system-wide climate change may be in the works, threatening ocean marine ecosystems such corals, fisheries, and aquaculture, as well as goosing up terrestrial temperatures way too fast too soon across the planet. Marine heatwaves this decade have lasted four times (4x) longer than the historical record. Hot oceans accelerate climate change. As water temperatures rise, oceans lose ability to absorb excessive heat and land temperatures rise accordingly.

“According to the study’s researchers, the 2023 MHWs........
