Earth had its sixth-warmest June on record

Globally, June 2022 was the sixth-warmest June in the 143-year NOAA record. The year-to-date (January-June) global surface temperature was also the sixth warmest on record. According to NCEI’s Global Annual Temperature Outlook, there is a greater than 99% chance that 2022 will rank among the 10-warmest years on record but only an 11% chance that […]

Earth had its Fifth-warmest March on Record

The global temperature for March 2022 was the fifth highest for March in the 143-year NOAA record, which dates back to 1880. The year-to-date (January-March) global surface temperature was also the fifth warmest such period on record. According to NCEI’s Global Annual Temperature Rankings Outlook, it is virtually certain (> 99.0%) that the year 2022 […]

October 2021 ENSO update: La Niña is here!

Our second-year La Niña has materialized, as indicated by the ocean and atmosphere in the tropical Pacific. There’s an 87% chance of La Niña this winter, the season when North American weather and climate are most affected by ENSO (El Niño/Southern Oscillation, the entire El Niño/La Niña system). The winning numbers The first step on our […]

NOAA predicts another active Atlantic hurricane season

NOAA’s Climate Prediction Center is predicting another above-normal Atlantic hurricane season. Forecasters predict a 60% chance of an above-normal season, a 30% chance of a near-normal season, and a 10% chance of a below-normal season. However, experts do not anticipate the historic level of storm activity seen in 2020.  For 2021, a likely range of […]

May 2021 ENSO update: bye for now, La Niña!

La Niña conditions have ended and NOAA forecasters estimate about a 67% chance that neutral conditions will continue through the summer. The ENSO forecast for the fall is less confident, with odds of a second-year La Niña currently hovering around 50–55%. Spring cleaning If you’ve been paying very close attention to the surface temperature of the tropical […]

NOAA: The new U.S. Climate Normals are here. What do they tell us about climate change?

Every 10 years, NOAA releases an analysis of U.S. weather of the past three decades that calculates average values for temperature, rainfall and other conditions.   That time has come again. Known as the U.S. Climate Normals, these 30-year averages — now spanning 1991-2020 — represent the new “normals” of our changing climate. They are calculated using climate […]

Keeping score: The groundhog vs. the temperature record, 2021

February 2, 2021 – 10 contacted NID In Gobbler’s Knob, Pennsylvania, at the crack of dawn this morning, the nation’s most famous groundhog Punxsutawney Phil saw his shadow — meaning six more weeks of winter, according to longstanding folkloreoffsite link. How accurate was Phil’s 2020 ‘forecast’? Last year, Phil “predicted” a shorter winter and early spring when official observers declared he did not see his shadow. But in fact, […]

Fire fuels in high northern latitudes are becoming more flammable

December 14, 2020 – In the 2020 issue of NOAA’s Arctic Report Card, experts reported on the evolving wildfire landscape across the taiga—the boggy, coniferous forests that occupy much of the high northern latitudes. Rising air temperature and fuel availability over the past 41 years indicate that conditions in Earth’s largest terrestrial biome are becoming more […]

La Niña is likely to continue through the Northern Hemisphere winter 2020-21

December 10, 2020 – La Niña persisted during November, as indicated by well below-average sea surface temperatures (SSTs) extending from the Date Line to the eastern Pacific Ocean [Fig. 1]. Most of the weekly indices fluctuated through the month, with the westernmost Niño regions Niño-4 and Niño-3.4 ending up around -1.0°C [Fig. 2]. The negative equatorial subsurface […]
