The El Niño climate pattern has long influenced weather across the globe. @AndrewKingClim @ClimateFreund @JosephineRBrown @nicola__maher @adi_sen99 @OurANU @unimelb theconversation.com/extreme-…

It threatens to compound the worst effects of climate change. @ClimateFreund @unimelb theconversation.com/a-record…

La Niña seems still possible but not very likely. We looked at year to year transitions from El Niño and historically only 16.7% of all cases resulted into a La Niña the next year iopscience.iop.org/article/1…

A new study by Ruby Lieber, Dr. Josephine Brown, Dr. Andrew King and Dr. Mandy Freund reveals that ENSO teleconnections may amplify with climate change, leading to more severe temperature and precipitation extremes globally.

Reaching Net Zero is critical and our pathway towards Net Zero is also critical as it affects how our climate will look after we cease emitting Greenhouse gases. Go check out a new Briefing note by @ClimateExtremes to learn more about it.
#NetZero
What is net zero and what happens after we reach it? After net zero, the global average temperature is expected to roughly stabilise. Temperatures over land would begin to cool, while parts of the ocean continue to warm. Read our new briefing note here:

I am excited to see this study published @CommsEarth! It uses a deep learning model to infer summertime atmospheric blocking frequencies from seasonally averaged surface temperature reconstructions over the Last Millennium. 1/n nature.com/articles/s43247-0…

Signs of this potential La Niña are emerging fairly late. But new research may help make predictions earlier writes @ClimateFreund @unimelb theconversation.com/australi…

The precipitation stacked up along the strong thermal boundary, held in place by important areas of high pressure and enhanced by the orography.
The rain is still falling but we already know Austria rainfall records are being pulverised (more on that when the dust settles).

New paper led by Ruby Lieber and with @JosephineRBrown @ClimateFreund studies ENSO teleconnections with extremes. Ruby found amplification of teleconnections in many regions with global warming and this effect is stronger in models with strengthening ENSO journals.ametsoc.org/view/jo…

Excited to share our new paper on two multi century seasonal streamflow reconstructions for western Tasmania! We show streamflow has been declining in the last 100 years but the 15th century was much drier. Awesome team of co-authors👇sciencedirect.com/science/ar…

The Bureau of Meteorology has declared that El Niño and a positive Indian Ocean Dipole (IOD) are underway. Warmer and drier conditions have already been forecast for spring and summer for parts of Australia. Details: bom.gov.au/climate/enso/

Europe's summer #droughts since 2015 have been the most severe for centuries - but not the only multi-year droughts. This is shown by #isotope analyses of #tree rings across Europe, which thus prove to be a unique tool for #climate research.

Here: Principle of minimally invasive removal of a wood sample from a living tree trunk using an increment borer: A drill core about the thickness of a small finger is pulled out of the living tree trunk by hand. Tree rings allow precise dating centuries into the past: The isotope ratios of carbon 13C to 12C and oxygen 18O to 16O in the cellulose of the tree trunk are indicators of drought or moisture at the time of tree growth.

The 2015-2018 summer drought event was unprecedented in Western and Central Europe over the last 400 years, though multi-year droughts were more frequent during the Maunder Minimum.

What a fantastic retreat we had with a few @unimelb @ClimateCollege alumni this weekend. They are now active in government, industry and civil society - changing the course of Australia towards net-zero, one step at a time. Let's try to keep the ball in the air!

Pleased to see the final paper of my PhD published today! End of an era with many thanks to my supervisors @RobynSchofield3 Matt Woodhouse & @DrToddLane and the amazing team that made this work possible! @CSIRO @ANSTO @QUT @AusAntarctic @BOM_au @SciMelb So what is it all about?

Today is #WomeninScienceDay, and my former dept head just asked me if I would be ok being removed as a coauthor from a paper I worked on for more than a year. With the ongoing discussions about academic misconduct and abuse, I feel it's the right time to share my experience.

Almost 300 people tuning in to Prof David Karoly's retirement symposium this afternoon.
Past students, present students, international leaders in climate science, ozone, meteorology, policy and communication, David's career has shaped and inspired so many others!

These guys!! 😍😍😍😍
We're proudly cheering on the incredible @lindenashcroft, a 2021 Young Tall Poppy!
Linden investigates the past Australian climate to help us prepare for the future. She also does great #scicomm work combining science with stories. It's no doubt she won this prestigious award!
