#WMO's report on 2024, hottest year on record. Heatwaves in Japan left hundreds of thousands of people struck down by heatstroke. Soaring temps during heatwaves peaked at 49.9C at Carnarvon in Western Australia, 49.7C in city of Tabas in Iran, and 48.5C in nationwide heatwave in Mali.

Long-term climate warming and the increasing frequency and intensity of short-term heatwaves are significantly reducing surface dissolved oxygen (DO) levels in lakes worldwide, according to a new study published in Science Advances.
Extreme weather last year including typhoons, heat waves and flooding led to the biggest displacement of people since 2008, and exacerbated a food crisis in more than a dozen countries, according to a report. https://www.japantimes.co.jp/environment/2025/03/19/climate-change/extreme-weather-2024-16-years/?utm_medium=Social&utm_source=mastodon #environment #climatechange #climatechange #drought #floods #typhoons #heatwaves

"The authors note that one group of researchers found that the number of such #heatwaves in 2023–2024 was 240% higher than any other year in recorded history. They also note that the more often such heat waves occur, the more difficult it is for affected areas to recover."

"Floods, whale strandings and coral bleaching all more likely, say researchers, as 10% of ocean hits record high temperatures in 2023-24.
One of the most surprising findings in the study, said Smith, was “how much [#MarineHeatwaves] accentuated storms on land and the number of people that were hit by that – hurt, lost possessions, [suffered a] monetary impact or lost their lives”. "

Fire chiefs warn UK is not prepared for climate crisis impacts
The #UK is not prepared for the impact of #ClimateBreakdown, fire chiefs have said, as they called on the government to take urgent action to protect communities.
The National Fire Chiefs Council (#NFCC) said the ability of fire services to tackle #weather-related emergencies was at risk, despite them often being the primary frontline response to major weather events including #flooding, #fires caused by #heatwaves, and #storm-related emergencies, all of which are becoming more common.
The #MetOffice predicts that winters by 2070 will be as much as 4.5C #warmer and 30% #wetter than they were in 1990, while summers may be up to 6C warmer and 60% #drier. The south of England is projected to face temperatures reaching 40C (104F) and #rainfall is expected to increase by a quarter.

"A heat wave gap metric, the time between two adjacent heat wave events, was utilized to examine the gap length and frequency trend for several stations around New York City (NYC)... From 1961 to 1990 to 1991–2020, the average heat wave gap for the various stations decreased by 15–41 %, the number of short gaps (≤5 days) increased by 33–300 %, while the number of long gaps (>5 days) remained relatively constant."

#Climatechange added 41 days of #DangerousHeat around world in 2024
By ALEXA ST. JOHN
December 27, 2024
"People around the world suffered an average of 41 extra days of dangerous heat this year because of human-caused climate change, according to a group of scientists who also said that climate change worsened much of the world’s damaging weather throughout 2024.
"The analysis from World Weather Attribution and Climate Central researchers comes at the end of a year that shattered climate record after climate record as heat across the globe made 2024 likely to be its hottest ever measured and a slew of other fatal weather events spared few.
"'The finding is devastating but utterly unsurprising: Climate change did play a role, and often a major role in most of the events we studied, making heat, droughts, tropical cyclones and heavy rainfall more likely and more intense across the world, destroying lives and livelihoods of millions and often uncounted numbers of people,' Friederike Otto, the lead of World Weather Attribution and an Imperial College climate scientist, said during a media briefing on the scientists’ findings. 'As long as the world keeps burning fossil fuels, this will only get worse.'
"Millions of people endured stifling heat this year. Northern #California and #DeathValley baked. Sizzling daytime temperatures scorched #Mexico and #CentralAmerica. Heat endangered already vulnerable children in #WestAfrica. Skyrocketing southern #European temperatures forced #Greece to close the #Acropolis. In #SouthAsian and #SoutheastAsian countries, heat forced school closures. Earth experienced some of the hottest days ever measured and its hottest-yet summer, with a 13-month heat streak that just barely broke."

"For the year to date, the January-to-November global surface temperature ranked warmest in NOAA’s 175-year record. According to NOAA/NCEI’s statistical analysis, there is a greater than 99% chance that 2024 will rank as the warmest year on record, which would give the planet two consecutive warmest years on record. It appears unlikely Earth will again see a year in the 20th-century temperature range for many years to come unless there is major volcanic cooling, a major geoengineering push, and/or a sustained, worldwide effort to reduce fossil-fuel emissions."

One post upthread says that climate change has moved the Probable Maximum Precipitation.
Looks like the probably maximum heat also needs to be revisited.
"We should brace for worse-than-expected #heatwaves in the years ahead, as climate models are underestimating the potency of these events in some areas, including the UK and northern France, southern Australia and northern Canada."
