The third parade on Earth » Yale's climate connection

NOAA's National Center for Environmental Information (NASA) reportedly rated NASA and European European Copernicus Climate Change Services as March 2025 as the second and second third round of record. Data from the Japan Meteorological Service and Berkeley Earth were not obtained at the time of writing. Global temperatures so far in 2024 and 2025 are significantly higher than in any year before 2015.

According to NOAA, the global land region has a second-place parade in 2025. The warmest parades recorded in Europe and Oceania. Africa, the third helper; South America, the sixth reward; North America, the seventh reward; and Asia, the tenth reward. The Caribbean has its second heated parade. In March 2025, the northern hemisphere's snow cover was the seventh lowest since 1967.

The sixth consecutive US joining parade, with 5.4 degrees Fahrenheit (3°C) above average. The U.S. tornadoes in March were more than twice the monthly average; three independent outbreaks produced more than 200 tornados in total. The month ended with 296 tornadoes, 41 of which were EF2 or stronger. 515 tornadoes observed from January 1 to April. The 10 is the third highest annual total since 2010, behind only 2017 (539) and 2023 (530).

Global surface temperatures from January to March ranked second in NOAA's 176-year record. According to NOAA/NCEI statistical analysis, there is a 6% chance of the warmest year in 2025, and a 40% chance will be the second moderate, second only to 2024.

Nina's ending conditions No mature La Nina episode

NOAA reported in April's monthly discussion on the status of El Niño/Southern Oscillation or ENSO that LaNiña conditions in the Eastern Pacific ended in March. According to NOAA's definition, the conditions for LaNiña do not last for five overlapping three months, which is not enough to become a formal LaNiña plot. The Australian Meteorological Agency (using a tighter threshold than NOAA to define the LaNiña condition) did not recognize that the LaNiña conditions occurred this year, saying ENSO neutral conditions have prevailed so far in 2025.

According to NOAA's April forecast, ENSO neutral conditions may continue until August 2025. For the upcoming Atlantic hurricane season (August to September to October), the forecast from the Institute of Climate and Social Sciences at Columbia University International University calls for a 31% chance of getting LaNiña, and the Enso-so-so-se-ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni Elniño conditions tend to suppress Atlantic hurricane activity by increasing wind shears, but LaNiña conditions tend to have the opposite effect. We are in the midst of ENSO's low-skill “Spring Predictability barrier” (see Climate.gov's 2015 interpreter), so the confidence in the ENSO forecast released this month is lower than usual.

Although El Niño events usually last only one year (usually from the northern fall to the northern spring, like 2023-24), La Niña events usually have two or even three consecutive years of restriction or recurrence, just like from mid-2020 to early 2023.

Arctic Sea Ice: Minimal Winter Peaks and Minimum Parade Range Recorded

Arctic sea ice range since March 2025 was the lowest in 47-year satellite record, beating the 2018 record, according to the National Snow and Ice Data Center (NSIDC). On March 22, the sea ice range reached the highest range in winter, with the lowest range. During the first six days of April, the sea ice range set new record lows every day, beating the 2018 record lows, but by April 7, 2025, the ice range was only the second lowest recorded. The Arctic recorded the seventh temperature parade in 2025.

The Antarctic sea ice range in March was the fourth lowest in 47-year satellite record. The Antarctic set its 43rd winning parade in 2025.
