A few years ago, prior to Australia’s ‘Black Summer’, I began capturing extreme events as I became aware of them escalating to a frequency of becoming annual events - some type of disaster of unprecedented scale occurring somewhere where such an event was previously unheard of. 🧵

Recent south polar warmth (negative AAO → SAM; gradually easing) has pushed westerlies further north, and produced a wavier jet stream pattern with persistent mid-latitude cold and warm anomalies. Which longitudes are cold/warm is governed by planetary waves.

Climate change made Helene 200x more likely - but just 3% of TV news said so

Hot oceans caused by human fossil fuel use made Helene into one of the strongest storms ever. But only 3% of TV news made the connection. Why?

great thread on @paulmac.bsky.social's work tracking climate disasters. Worth a follow!

Paul Macdonald @paulmac.bsky.social · Nov 15

That the global population is not terrified for the wellbeing of their own offspring, let alone the wellbeing of others, to the point of rising up en masse to demand a global moratorium on fossil fuel expansion, would be utterly inconceivable,…

#AnthropogenicGlobalWarming

Extreme rainfall and historic flooding - scientific studies reveal that atmospheric rivers are no longer following their usual course and are altering the climate in the Americas, Europe and Asia

Atmospheric rivers are changing. If you have never heard this term, they are giant vapor currents that transport much more water than the Amazon, but it is

Marine heatwaves modulate food webs and carbon transport processes - Nature Communications

A decade of BGC-Argo and plankton records shows North Pacific heatwaves reshape food webs and trap small particles in midwater, slowing deep-ocean carbon export. Impacts vary by event, underscoring the need for sustained ocean monitoring.

Extreme Temperatures Around the World @extremetemps.bsky.social · 2d

190 countries + territories (most of the world) have already broken monthly heat records in these 6 days of October.

Needless to say, nothing even remotely close to this, had ever happened before.

High minimum records are at least tripling those of High maximums.
