Coinciding with the World Meteorological Organisation (WMO) releasing the State of the International Local weather 2024, Met Éireann has difficultyd Eire’s Local weather 2024 Provisional Abstract Report, which confirms final yr because the fourth warmest yr on file for Eire. In the meantime, WMO’s report paperwork 2024 because the warmest yr in global information, with key local weather change indicators once more reaching file ranges.
Met Éireann Senior Climatologist Dr Pádraig Flattery feedback: “2024 Provisional Abstract Report incorporates key annual, seasonal and month-to-month findings on temperature, rainfall and wind, and places the information within the context of the climatological averages for Eire, providing insights on the adjustments and developments our local weather is experiencing”.
1. Eire – 2024 Moodatures
2024 has been provisionally recorded because the fourth warmest yr on file for Eire, with a mean temperature of 10.72 °C. That is 1.17 °C above the 1961-1990 climatological normal regular interval (Determine 1) and 0.55 °C above the 1991-2020 Lengthy-Time period Common (LTA). 2024 additionally noticed the warmest Could ever recorded.
Determine 1: Eire’s temperature anomalies from 1900 to 2024 in comparison with the 1961-1990 climatological normal regular interval. The black line is a LOESS trendline, which makes use of a 42-year window to clean out patterns within the information over time. The graph exhibits a warming development which is in keeping with international developments.
Dr Flattery continues: “2024 was Eire’s fourth warmest yr on file, and follows our warmest yr ever recorded, which was 2023. Rising temperatures enhance the possibility of extreme climate occasions and emphasise the necessity for local weather motion to cut back greenhouse gasoline emissions, as nicely as strong adaptation to take care of the implications of local weather change”.
With seven of the ten warmest years in Eire having occurred since 2005, 2024 continues the development of elevated temperatures. The very best temperature recorded this yr was 26.6 °C at Phoenix Park on June twenty fourth, 12.7 °C above the June LTA, whereas the bottom temperature was -7.3 °C at Athenry, Co. Galway on January 18th, 13.3 °C under its January LTA. Gridded common imply air temperatures and anomalies are proven in Determine 2.

2. Eire – 2024 Rainfall
When it comes to rainfall, 2024 is provisionally the thirty ninth wettest or forty sixth driest yr since 1941, making it a near-average yr for rainfall total. The east of Eire skilled the driest situations, whereas the south noticed extra rainfall than common (Determine 3 under). The very best each day rainfall whole at a main station occurred at Knock Airport, Co. Mayo, the place 57.4 mm fell on November 23rd throughout Storm Bert, accounting in a single day for 40% of its November LTA.

3. Eire – 2024 Wind and Storms
2024 noticed seven named storms affect Eire, together with Isha, Jocelyn, Kathleen, Lilian, Ashley, Bert, and Darragh. Notably, Storm Darragh introduced the strongest winds of the yr on December 6th, with a gust of 76 knots (141 km/h) and a ten-minute imply wind velocity of 60 knots (111 km/h), each recorded at Mace Head, Co Galway. Storm Isha in January 2024 additionally introduced violent storm-force winds to the nation.

4. WMO State of the International Local weather 2024: One other File-Breaking 12 months
The World Meteorological Group’s (WMO) State of the International Local weather 2024 report confirms that final yr was the warmest on file, globally, with a worldwide imply temperature of 1.55 ± 0.13°C above pre-industrial ranges. This marks the primary full calendar yr exceeding the 1.5°C threshold, though long-term warming stays barely under this restrict.
Determine 5: Annual international imply temperature anomalies relative to a pre-industrial (1850–1900) baseline proven from 1850 to 2024 Supply: WMO, information are from the six datasets (every dataset in a unique color line)
Key Findings:
- File-breaking greenhouse gasoline concentrations, with CO₂ ranges reaching their highest in 800,000 years.
- Globally every of the previous ten years have been individually the ten warmest years on file, with 2024 surpassing all of them.
- Unprecedented ocean warmth, with eight consecutive years of record-high ocean temperatures.
- Accelerating sea-level rise, now occurring at twice the speed noticed within the early satellite tv for pc period.
- Arctic and Antarctic ice at historic lows, with Antarctic sea ice reaching its second-lowest extent ever recorded.
- Glacier loss at file ranges, with probably the most important three-year decline in historical past.

The Position of El Niño and Local weather Change
The mix of long-term greenhouse gasoline emissions and a robust El Niño occasion drove 2024’s excessive temperatures. Nonetheless, extra elements—together with shifts in photo voltaic exercise, volcanic eruptions, and lowered cooling aerosols—might have amplified the warming.
The Value of Inaction
Excessive climate occasions in 2024 led to widespread displacement, financial losses, and worsening meals crises. WMO emphasizes the urgent have to strengthen early warning programs, as solely half of all international locations presently have ample local weather preparedness.
“Each fraction of a level issues,” stated WMO Secretary-Normal Celeste Saulo. “Funding in local weather providers is essential to defending lives and economies.”
The WMO report serves as a crucial reminder forward of the inaugural World Glaciers Day (21st March), World Water Day (twenty second March) and World Meteorological Day (23rd March).
