Scientists calculate that last year was one of the three hottest on record, along with 2024 and 2023.

The United Nations weather agency said carbon dioxide levels in the atmosphere reached record highs last year, intensifying climate change and extreme weather.

Last year was the hottest year on record, the top 10 hottest years were all in the past decade and planet-heating carbon dioxide in the atmosphere is at its highest levels in the last 800,000 years, a report Wednesday said.

The U.N. weather agency is reporting that 2023 was the driest year in more than three decades for the world’s rivers, as the record-hot year underpinned the drying up of water flows and contributed to prolonged droughts in many places.

Winter sports are facing a long-time crisis because of climate change and the International Ski and Snowboard Federation has teamed up with the United Nations weather agency.

The U.N. weather agency is sounding a “red alert” about global warming, citing record-smashing increases last year in greenhouse gases, land and water temperatures and melting of glaciers and sea ice.

The U.N. weather agency is reporting that glaciers shrank more than ever from 2011 and 2020 and the Antarctic ice sheet lost 75 percent more compared to the previous ten years, as it released its latest stark report about the fallout on the planet from climate change.

The U.N. weather agency says 2023 is all but certain to be the hottest year on record, and warning of worrying trends that suggest increasing floods, wildfires, glacier melt, and heat waves in the future.

July has been so hot so far that scientists calculate that this month will be the globally hottest on record and likely the warmest human civilization has seen, even though there are several days left to sweat through.

The World Meteorological Organization, an agency of the UN, said the first week of July was the hottest week on record for the planet as a whole.

The U.N. weather agency reported Monday that nearly 12,000 extreme weather, climate and water-related events over much of the past half-century around the globe have killed more than 2 million people and caused economic damage of $4.3 trillion.

The United Nations' weather agency says there's a two-out-of-three chance that the world will reach the internationally accepted global temperature threshold for limiting the worst effects of climate change sometime in the next five years.

Looking back at 2022’s weather with months of analysis, the World Meteorological Organization says last year really was as bad as it seemed when people were muddling through it.

Storm names are retired when the storms become so deadly and destructive

There were 14 named storms, 8 hurricanes and 2 major hurricanes this season

The United Nations' weather agency says the state of Earth's climate is bad and getting worse faster than before, especially with sea level rise accelerating.

The three main greenhouse gases hit record high levels in the atmosphere last year, the U.N. weather agency said Wednesday, calling it an “ominous” sign.

The temperature rose to triple digits in the Russian town located north of the Arctic Circle

The U.N. weather agency has certified a 38-degree Celsius (100.4 Fahrenheit) reading in the Russian town of Verkhoyansk last year as the highest temperature ever recorded in the Arctic.

The U.N. weather agency says greenhouse gas concentrations hit a new record high last year and increased at a faster rate than the annual average for the last decade.

The U.N. weather agency says the world and especially urban areas experienced a brief and sharp drop in emissions of air pollutants last year.

A new report from the United Nations weather agency finds the world is getting several times more weather disasters than in the 1970s.

Italy is baking in sweltering temperatures that continue to drive deadly wildfires.

A new world weather agency forecast says it'll likely be so hot in the next five years that there's a 40% chance the globe will push past the temperature limit set by the Paris climate agreement.

Nine Greek alphabet letters were used to name tropical storms and/or hurricanes in 2020. The organization has created a supplemental list of names with the standard alphabet that can be used when the yearly list is exhausted. Hurricane names retired by the World Meteorological Organization (Copyright 2021 by WSLS 10 - All rights reserved.) Leah is the new name on the 2020 list, to be used in lieu of Laura in 2026. As the Greek alphabet will not be used again, there are no replacements for Eta and Iota.

(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.

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.

DEATH VALLEY NATIONAL PARK, Calif. An automated measuring system in California's Death Valley reported a temperature of 130 degrees (54.4 degrees Celsius) amid a blistering heat wave on Sunday, a reading that would be among the highest ever recorded globally if it is confirmed. If verified, this will be the hottest temperature officially verified since July of 1913, also at Death Valley. As this is an extreme temperature event, the recorded temperature will need to undergo a formal review," the statement said. That temperature was 131 degrees (55 Celsius) recorded in Kebili, Tunisia, on July 7, 1931, and it also is disputed. Death Valley, an austere landscape in the desert of southeastern California, includes Badwater Basin, which at 282 feet (85.9 meters) below sea level is the lowest point in North America.

A Siberian town that endures the world's widest temperature range has recorded a new high amid a hear wave that is contributing to severe forest fires. Russia's meteorological service said the thermometer hit 38 Celsius (100.4 F) on Saturday in Verkhoyansk, in the Sakha Republic about 4660 kilometers (2900 miles) northeast of Moscow. (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.

After all the years of recorded named storms, one has to wonder: What happens when we run out of names? “The World Meteorological Organization came up with a six-year rotating list of names for hurricanes,” Gross said. Now we arrive at our initial question: What happens when we run out of names? So, let’s say we have a storm named Walter. The first and last instance in which the Greek alphabet was needed was in 2005, during the busiest hurricane season on record, when there were 28 named storms.
