‘Alarming’ Global Warming Smashes Records for 9th Straight Month
March 7, 2024 – the Energy mix | Full Story: The Associated Press | Primary Author: Seth Borenstein
For the ninth straight month, Earth has obliterated global heat records—with February, the winter as a whole, and the world’s oceans setting new high-temperature marks, according to the European Union climate agency Copernicus.
The latest record-breaking in this climate change-fueled global hot streak includes sea surface temperatures that weren’t just the hottest for February, but eclipsed any month on record, soaring past August 2023’s mark and still rising at the end of the month. More

The world just experienced its warmest January on record, marking the first 12-month period in which temperatures averaged more than 1.5C (2.7F) above pre-industrial times, the European Union’s climate change monitoring service said on Thursday.
2023 Made Life ‘Miserable, Sometimes Deadly’ as Warmest Year on Record
January 10, 2024 – the Energy Mix
Earth last year shattered global annual heat records, flirted with the world’s agreed-upon warming threshold, and showed more signs of a feverish planet, the European climate agency said Tuesday.
The European climate agency Copernicus said the year was 1.48°C (2.66°F) above pre-industrial times, The Associated Press reports. That’s barely below the 1.5° limit the world hoped to stay within in the 2015 Paris climate accord to avoid the most severe effects of warming.
It is now official: November 2023 was the warmest November on record
November 2023 indeed broke records as the hottest November ever recorded. The global mean temperature for this month soared to 1.43 degrees Celsius above pre-industrial levels, surpassing all previous Novembers1. This warming trend is part of a larger pattern: 2023 is on track to become the hottest year on record1
The numbers are coming in for October and they’re not good.
< Here’s how October 2023 compares to the last 80 Octobers.
Not quite as “gobsmackingly bananas” as September but this year’s radical temperatures are continuing. September was about 1.8 C above pre-industrial temperatures, October was about 1.7 C.
< Here’s an update on the radical departure of 2023 from previous years
It’s “virtually guaranteed” to be the hottest year on record, and for at least 125,000 years.
“The amount that we’re smashing records by is shocking,” said Samantha Burgess, deputy director of the Copernicus Climate Change Service.
Hottest September ever
Oct 14, 2023 – Environment and Climate Change Canada
According to the Copernicus Climate Change Service, September 2023 emerged as the hottest September ever documented worldwide, shattering previous records by a significant margin.
September’s average temperature was 16.38°C, surpassing the previous record set in 2020 by 0.5°C. It was also 1.75°C warmer for the month of September compared to the pre-industrial reference period (1850-1900).

Since June 2023, the world has experienced an extraordinary surge in heat on land and in the oceans. This is unlike anything we’ve seen before. Other climate variables provide additional evidence of this extraordinary heat, with this year’s Antarctic maximum sea ice extent reaching an all-time low.

The recent record-breaking warming of land and ocean temperatures highlights how natural climate fluctuations can add to and amplify the ongoing warming due to emissions of greenhouse gases from human activity. Over recent months, numerous longstanding high-temperature records have crumbled, putting 2023 on track to become the hottest year on record worldwide.
Hottest July on record
The global average temperature for July 2023 is confirmed to be the highest on record for any month. The month was 0.7°C warmer than the 1991-2020 average for July, and 0.3°C warmer than the previous warmest month, July 2019. The month is estimated to have been around 1.5°C warmer than the average for 1850-1900.
Heatwaves were experienced in multiple regions of the Northern Hemisphere, including southern Europe. Well-above average temperatures occurred over several South American countries and around much of Antarctica. El Niño conditions continued to develop over the equatorial eastern Pacific. Marine air temperatures were well above average in several other regions.

Ocean heat record broken, with grim implications for the planet
Aug 4, 2023 – BBC
The oceans have hit their hottest ever recorded temperature as they soak up warmth from climate change, with dire implications for our planet’s health.
The average daily global sea surface temperature beat a 2016 record this week, according to the EU’s climate change service Copernicus.
It reached 20.96C (69.73F) – far above the average for this time of year.
‘Uncharted territory’: UN declares first week of July world’s hottest ever recorded
July 11, 2023 – the Guardian
“The world just had the hottest week on record, according to preliminary data,” the WMO said in a statement, adding that temperatures were breaking records on land and in the oceans, with “potentially devastating impacts on ecosystems and the environment”.
“We are in uncharted territory and we can expect more records to fall as El Niño develops further and these impacts will extend into 2024,” said Christopher Hewitt, WMO director of climate services.
“This is worrying news for the planet.”
For the third time this week, Earth sets an unofficial heat record.
Monday, July 3: 17.01 Celsius (62.6 degrees Fahrenheit), Earth’s highest ever average global temperature.
Tuesday, July 4: 17.18 Celsius, breaking the previous record set Monday!
Wednesday, July 5: 17.18 Celsius, remaining at the record high set the day before.
Update – Thursday, July 6: Global temperatures reached a new high of 17.23 Celsius, noted AP.
UK weather: hottest June since records began – Met Office
July 3, 2023 – Georgina Rannard – BBC
The average monthly temperature of 15.8C (60.4F) exceeded the previous highest average June temperature, recorded in 1940 and 1976, by 0.9C.
Climate change made the chance of surpassing the previous joint record at least twice as likely, scientists also said.
Records were broken in 72 of the 97 areas in the UK from which temperature data is collected.
Spain breaks record temperature for April – BBC News
April 28, 2023 – BBC News
Spain recorded its hottest ever temperature for April on Thursday, hitting 38.8C according to the country’s meteorological service.
The record figure was reached in Cordoba airport in southern Spain just after 15:00 local time (14:00 BST). For days a blistering heatwave has hit the country with temperatures 10-15C warmer than expected for April. It’s been driven by a mass of very hot air from Africa, coupled with a slow moving weather system.

Great Lakes ice coverage reaches historic low
NOAA researchers at NOAA’s Great Lakes Environmental Research Laboratory (GLERL) report that they’ve seen a steady decrease in ice coverage across the Great Lakes, which has reached a historic low.
“We’ve crossed a threshold in which we are at a historic low for ice cover for the Great Lakes as a whole,” says GLERL’s Bryan Mroczka, a physical scientist. “We have never seen ice levels this low in Mid-February on the lakes since our records began in 1973.” NOAA Research Read article
Canada’s “hellish” wildfire season defies the calendar
Sept 29, 2023 – Andrew Freedman – Axios
Canada’s wildfire season, already the worst on record, went “completely off the rails” during the past week, scientists tell Axios.
The big picture: Enough land area burned in the past week to make the seven-day-period comparable to nearly an entire typical fire season across Canada, according to Merritt Turetsky of the University of Colorado.
- While five provinces and territories, stretching from Nova Scotia to the Northwest Territories, saw record amounts of land burned this season, western Canada has been hit the hardest, she said in an interview.
- “Things have just continued to play out in kind of a hellish way in western Canada,” she said.
- During the past few days, smoke from wildfires in British Columbia and the Northwest Territories has tinted the skies over Greenland and northern Europe.
These fires are burning at a time of year when Canada’s fire activity tends to be on a sharp decline.

Wildfires burning through large swathes of eastern and western Canada have released a record 160 million tonnes of carbon, the EU’s Copernicus Atmospheric Monitoring Service said on Tuesday.
This year’s wildfire season is the worst on record in Canada, with some 76,000 square kilometres (29,000 square miles) burning across eastern and western Canada. – more
Donnie Creek wildfire is now the largest in B.C.’s history
June 19th 2023 – By Brieanna Charlebois – National Observer
The Donnie Creek wildfire has grown into the largest blaze ever recorded in British Columbia, BC Wildfire Service said Sunday.
The fire, which is burning south of Fort Nelson in northeastern B.C., is now estimated at more than 5,343 square kilometres in size.
It surpasses the Plateau fire that charred 5,210 square kilometres northwest of Williams Lake in 2017 and was previously considered the province’s largest fire. – more
