We're proud to announce we're moving away from investment in fossil fuels. By 2025, we'll divest from companies whose primary business is the ownership and exploitation of fossil fuels as part of our commitment to being a world-leader in climate science. newsroom.unsw.edu.au/news/general/u…

@paul_n_pearson You seem to forget the Dutch “urgenda” case? Google it, that was quite spectacular last December. In any case, great to see change is coming!

@AASPTPS Perfect!

@UU_oceaNice We do have an online only option for membership which we encourage and is far cheaper

Dear Members, many of your profiles DO NOT have addresses on them. Therefore, if you're signed up to receive the hard copy of our journal where are we supposed to get the publisher to send them?!?! Please check your online details if you want to receive your copy #Palynology

Happy longest day Antarctica!

"‘Het gaat het voorstellingsvermogen een beetje te boven’, zegt Van den Broeke. ‘Met een vertaalslag naar Olympische zwembaden red je dit niet meer.’" Ook de @volkskrant schrijft over de @nature-publicatie van vandaag: volkskrant.nl/nieuws-achterg…

Happy #antarcticaday!

60 years of the Antarctic Treaty! today is Antarctica Day! #OnThisDay #OTD in 1959, 12 countries agreed to set aside #Antarctica “for peaceful purposes only”, as a scientific preserve for "the progress of all mankind”. Today 54 nations are party to the Treaty.

@MargotCram However it is really difficult to show the rate of collapse that has occurred in these geologic events. I also have problems with the work "retreat" in this matter, as it is a notion of the "action" rather than the "end state" that is reconstructed.

@MargotCram the word "collapse" is often used in this paleocontext, and then relates to the observation that the ice sheet is "much smaller than at present". Such reconstructions provide clues to the new equilibruim state of the ice sheet under a warmer climate condition,...

"To address these issues, we need models that capture a richer suite of couplings and feedbacks in the Earth system, and we need more data — present and past — and better ways to use them." nature.com/articles/d4158…

@rdlarter @flimsin @AGCGraham @nick_golledge Part of this misunderstanding may be that paleo sometimes uses the word ‘collapse’ of the ice sheet in past warm climates while they actually document a ‘retreated’ ice sheet, with no information on the rates of change that occurred. Job for reviewers!

@flimsin @AGCGraham @nick_golledge I mean actual physical palaeo evidence of widespread collapse. I'm well aware that there are model studies that say the WAIS should have collapsed, and the difficulty of explaining the sea-level highstand otherwise.

Interesting commentary, but this statement caught my eye: “Palaeo-evidence shows that such widespread collapse of the West Antarctic ice sheet has occurred repeatedly in the past.” 1/2 Climate tipping points — too risky to bet against nature.com/articles/d4158…

Aurora is de Romeinse godin van de zonsopkomst, ze rijdt voor de zon uit langs de hemel, om hem aan te kondigen. Als dichters in het oude Rome over de "rozige vingers" van Aurora schreven, bedoelden ze haar kleurenspel tegen de nog donkere ochtendhemel. Je weet wat Borealis is.

Wist je dat er ook onderzoek wordt gedaan in de tuinen? In kweekvijvers in de kassen kweken Utrechtse plantenfysiologen het plantje Azolla: de kroosvaren. Het plantje biedt veel potentie als veevoer, bioplastics en biodiesel. @UUBeta uu.nl/botanischetuin…

"She's going down!" Shackleton shouted #OnThisDay #OTD in 1915 Endurance finally sank beneath the sea ice of the Weddell Sea, all survived. Built in Norway in 1912, the ship was sold to Shackleton in 1914. "Fortitudine vincimus" (By endurance we conquer) - Shackleton family motto

Look at all that ice -on land and sea- if the greenhouse gases were gone!

Look at @UUGeo @Frida_SH sampling the hack out of that core!
