(NOAA via AP)With named storms coming earlier and more often in warmer waters, the Atlantic hurricane season is going through some changes with meteorologists ditching the Greek alphabet during busy years. The Greek alphabet had only been used twice in 2005 and nine times last year in a record-shattering hurricane season. AdMeanwhile, the National Oceanic Atmospheric Administration is recalculating just what constitutes an average hurricane season. STARTING EARLIERMIT hurricane researcher Kerry Emanuel said “this whole idea of hurricane season should be revisited." So a warming world means the new normal is busy hurricane seasons just like the last 30 years.

“There is at least a one-in-five chance of it temporarily exceeding 1.5 degrees Celsius by 2024,” WMO Secretary-General Petteri Taalas said. The Paris climate accord set a goal of not exceeding 1.5-degree (2.7 degrees Fahrenheit) warming since pre-industrial times. --Death Valley, California, hit 129.9 degrees (54.4 degrees Celsius), the hottest the world has seen in 80 years. --Record wildfires struck California and Colorado in the western United States, following a major fire season and record heat in Australia. --The Arctic had record wildfires and a prolonged heat wave culminating in a 100-degree mark (38 degrees Celsius) in Siberia in June.

The National Hurricane Center wasted no time moving onto the Greek alphabet -- only the second time since the 1950s. The only time the hurricane center dipped into the Greek alphabet was the deadly 2005 hurricane season, which included Hurricane Katrina’s strike on New Orleans.

The supercharged Atlantic hurricane season has produced so many named storms that scientists ran out of traditional names as Tropical Storm Wilfred developed in the eastern Atlantic.

JACKSONVILLE, Fla. Weve only got four names left unused (Sally, teddy, Vicky, & Wilfred) on the 2020 Hurricane names list and we are approaching the peak of the Atlantic Hurricane Season. Once we exhaust those names we move on to the Greek Alphabet for storm names like Alpha, Beta, Delta, Gamma, Epsilon, etc. While there are 26 letters in our traditional alphabet, there are only 22 storm names on the annual hurricane lists, skipping letters like Q, U, X, and Z. There are six rotation lists of names that the WMO uses for hurricane names. The 2005 hurricane season has the most retired names five for one season.

GENEVA The United Nations weather agency says this summer will go down for leaving a deep wound in the cryosphere -- the planets frozen parts -- amid a heat wave in the Arctic, shrinking sea ice and the collapse of a leading Canadian ice shelf. The weather agency said in a statement that many new temperature records have been set in recent months, including in the Russian town of Verkhoyansk. The town, located in Siberia above the Arctic Circle line, reached 38 degrees Celsius (100 F) on June 20. She noted a heat wave across the Arctic, r ecord-breaking wildfires in Siberia, nearly record-low sea ice extent, and the collapse of one of the last fully intact Canadian ice shelves. The WMO is preparing to release on Sept. 9 a report on the impact of climate change on the cryosphere.

The United States recently handed the world record for longest lightning flash over to Brazil. A separate megaflash set a record in Argentina for the longest reported single lightning bolt duration. The previous record for the longest detected distance for a single lightning flash was 199.5 miles on June 20, 2007, across Oklahoma. The previous record for duration was for a single lightning flash that lasted continuously for 7.74 seconds over Provence-Alpes-Cte dAzur, France, was broken after experts confirmed a 16.73-second-long single lightning flash 16.73 that developed continuously over northern Argentina on March 4, 2019.

(Olga Burtseva via AP)GENEVA The U.N. weather agency is investigating media reports suggesting a new record high temperature of over 38 degrees Celsius (100.4 degrees Fahrenheit) in the Arctic Circle amid a heatwave and prolonged wildfires in eastern Siberia. The World Meteorological Organization said Tuesday that its looking to verify the temperature reading on Saturday in the Russian town of Verkoyansk with Roshydromet, the Russian federal service for hydro-meteorological and environmental monitoring.
