This is precisely why seasonal predictions are the best source of information for weather/climate conditions in coming months. They consider many more influences than simply La Nina or other large scale drivers

Very happy to see the first paper published by my PhD student Xinyue Zhang @ccrc_unsw @ClimateExtremes. The good news is that less than 4% of drylands will desertify due to climate change (poor land use practices could still do it though)

Thought recent Australian droughts have been severe? New research suggests droughts could be much worse -even without climate change. Fantastic effort leading this study by @raindrop_herder and Nicky Wright paper: https://t.co/n3C9v6379j

Natural variability in Australian rainfall can produce “mega-droughts” lasting 20 years or more. Add in human-caused climate change, and future droughts may be far worse than imagined.

we're not in a La Nina. We're in an El Nino, that's ending. It's too early to say that La Nina is developing or "taking hold". **IF** La Nina develops, there's no physical way that current warm ocean temperatures are a result of something that MIGHT happen in the future. 🤦♀️🤦♀️🤦♀️
Water temperatures at beaches across Sydney have reached a record high, thanks to La Nina and the effects of climate change. @hayleyefrancis #9News

Check out this excellent new study on the Tinderbox Drought and its multiple drivers, an exceptionally extreme event that helped enable Australia's Black Summer fires in 2019-2020. The full article can be accessed here: https://t.co/fZhujh7I3e

It's cheaper to physically and permanently reduce emissions than to emit and let Earth suffer the consequences. The problem? We're simply not acting rationally. #AMOS2024

And thank you to the flux site PIs for sharing the eddy covariance data, it really is incredibly valuable for land modelling

The first PLUMBER2 MIP paper is now available as a preprint -the most comprehensive evaluation of land models at flux sites to date. Thank you to all the modellers who made this possible! 🙏The simulations are freely available, get in touch if interested

The @CopernicusECMWF team announce that 2023 was hottest on record, about 1.48°C above pre-industrial levels. "2023 was an exceptional year, with climate records tumbling like dominoes," says @OceanTerra Great graphics in this BBC article about the data: https://t.co/Hfhf7Y9mqp

FYI: BoM declared El Nino & pIOD underway in September 2023. Sep 2023 was driest Sep on record & 2nd driest any-month on record for Aus (124 years of record) Oct 2023 was 5th driest Oct on record for Aus Aug-Oct 2023 driest Aug-Oct on record & driest any 3-month period on record
