NOW: The year 2024 surpassed this record, reaching 1.54 degrees Celsius above the baseline in the first nine months and becoming the first calendar year to temporarily breach the 1.5 degrees Celsius threshold.
- ▶
BEFORE: Global ocean heat content had peaked and set records in 2023. NOW: Ocean heat content set a new record in 2024, continuing an unbroken eight-year streak of record-breaking ocean warming that accelerates sea-level rise and ocean acidification.
- ▶
BEFORE: The 2023 warming trend was initially developing without the full effect of the El Nino weather pattern. NOW: A strong El Nino peak in early 2024 compounded the long-term warming from anthropogenic greenhouse gases, turbo-charging global temperatures to unprecedented highs.
