Is Earth 'on the brink'? 2024 was likely our planet’s hottest year in 125,000 years 2024 may have been Earth's hottest year in at least 125,000 years, according to a grim climate report published Wednesday (Oct. 29) that describes our world as "on the brink" and warns its "vital signs are flashing red," with nearly two-thirds showing record highs. Last year had already been declared the hottest on record (those records dating back to the late 1800s), following 2023 — which used to be considered the warmest year in human history. The year 2024 also capped a decade of record-breaking heat fueled by human-caused climate change, continuing a trend that began in 2015. Now, the new report, led by researchers at Oregon State University, suggests the year was also likely hotter than the peak of the last interglacial period, roughly 125,000 years ago, when natural shifts in Earth's orbit and tilt made the planet warmer and sea levels several meters higher. That result is based on previously published climate studies. The study concludes that 22 of 34 measurable indicators of Earth's health, including greenhouse gas levels, ocean heat, sea ice and deforestation, have reached record extremes. The authors warn that these trends suggest humanity is in a "state of ecological overshoot," consuming the planet's resources faster than they can be replenished. Source:Space.com @EverythingScience
