The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Australia Stays Warm with Record Heat During Late Fall
Dear Diary. May in the Southern Hemisphere is the third month of autumn, so late fall in my book. Across most of Australia the weather has been anything but fall like going into winter with record warmth being reported from the island continent from many stations over the last month such as these:
AUSTRALIA RECORD HEAT Summer like temperatures keep sweeping Australia at the end of autumn including Tasmania which broke May records: 23.1 King Island 21.1 Smithton
Next days more summer heat in Western Australia with Perth rising again >30C ! That 's just crazy pic.twitter.com/q1DS4rOyPi

The most remarkable event is the incredible warm nights in Tasmania: Minimum 17.2 Low Rocky Point is only 0.5C from Tasmanian Highest minimum ever recorded in November Record heat in australia seems perennial, just moving around

April 2025 in New Zealand was also very warm. A total of 30 records of highest max. and highest minimums were broken. See a list below courtesy of NIWA: pic.twitter.com/XdBxLtvzsi

In fact, I would not be surprised to learn that Australia has had its warmest fall in recorded history when climatological data gets crushed in early June.
A mid-summer like heat dome will persist over Australia through this week and only get stronger as the week goes on:
I”ll be reporting more Australian “ETs” each day that this “warm wave” keeps on keeping on in the place I always reserve for these below:
Here are more “ET’s” recorded from around the planet the last couple of days, their consequences, and some extreme temperature outlooks, as well as any extreme precipitation reports:
AUSTRALIA-SOUTHERN AFRICA-SOUTH AMERICA The endless summer
Scorching heat never ends in SOUTH AFRICA Today 35.7 at Alexander Baai, which is just the beginning of a new fierce heat wave with widespread 30/35C even on the highlands,like in mid summer

Fierce heat return to Central Asia as well: 40.3 in Turkmenistan, 38C in Kazakhstan
where Bayyrkum set a new May record with 36.5C (few days after breaking that of April).
The heat will get much worse next days and will continue for any foreseeable future. https://t.co/9OWy0PY48w

Today, Yuanyang reached 40.4C, setting a new record high for China this year, and AWS reached 41.4C. The temperature in central and eastern China will gradually rise in the next week, and it is expected that a large area will break the record again around May 13! @extremetempspic.twitter.com/8raY4bSQcp
First 32C/90F in Canada and 4th day >30C. After the 29C+ in Ontario at the end of April,30C was surpassed from West to East in British Columbia,Alberta,Saskatechewan and Manitoba even at 600/700m asl. pic.twitter.com/O5Ltvhxo91

Last month observed temperature anomalies more than 5°C above the 1981-2010 average across parts of Siberia. Elsewhere, most areas were also anomalously warm, except around the Fram Strait/Greenland Sea and Hudson Bay.High resolution version updated monthly at zacklabe.com/arctic-tempe….
(As usual, this will be a fluid post in which more information gets added during the day as it crosses my radar, crediting all who have put it on-line. Items will be archived on this site for posterity. In most instances click on the pictures of each tweet to see each article. The most noteworthy items will be listed first.)
April 2025 was the second warmest April on record (after 2024) in the ERA5 dataset, at around 1.51C above preindustrial levels: pic.twitter.com/3QnaGvscmb
As you may have heard trumpeted by climate skeptics, there was a record-breaking mass gain for the Antarctic ice sheet from 2021 to 2023, thanks to increased precipitation in East Antarctica. This is what it looks like in context👇(h/t Marcus Gibson)
Three apparently contradictory things can all be true:1/ This is a great study – such a clear and obvious conclusion..2/ Yet caring isn’t enough. People need efficacy: and no one can re-ice a lake singlehandedly..3/ And while this is a new study, both concepts were in my TED talk 7 yrs ago.
The title of this article is incorrect. Special journal issues cannot replace a full NCA which, among many other things, requires review by 12 federal agencies & the National Academy, as well as engagement. But the article itself, written by @borenbears.bsky.social, is solid + well worth a read!
I think think of this as the “head, heart, hands” approach. To catalyze action, we need to know what’s happening, why it matters to us, and what we can do about it. All three!TED here: www.youtube.com/watch?v=-Bvc…Updated discussion here:
Though it's always a pleasure to chat with @andrewmueller.bsky.social, our topic was not pleasant at all: the dismantlement of science, research, & higher-ed to date, and how the repercussions will echo through the US economy, workforce + global leadership for DECADES. They have a very long tail.
Recommended read: @al-jazeera-english.bsky.social ran a long-read about efforts led by Brazil’s Indigenous Maxakali community to protect and restore the rainforest in Minas Gerais.

An evening prayer for ash trees, Fraxinus. The majority of ash trees are in decline or at risk of extinction. Most North American ash trees are threatened by emerald ash borer; European ash trees are threatened by ash dieback. The prayer is that we exert enough resources to prevent their extinction.
