How awesome that the best cartoon ever, mysterious cities of gold is back on tv after all these years for my son to watch! #80s #MCOG

“People need to see these [bleaching] events not as depressing bits of news that adds to other depressing bits of news. They are clear signals the Great Barrier Reef is calling for urgent help and for us to do everything we can.” theguardian.com/environment/20…

Today we're celebrating #WorldHeritageDay. #UNESCO World Heritage sites are precious, representing humanity’s greatest achievements. Our #AustralianMarineParks contain some of Australia’s 20 World Heritage sites, including spectacular #LordHoweMarinePark.📷#prodivelordhoweisland

@neilgundel @McgowanHamish @JohnFBruno @abcnews Maybe enough for real change? Or maybe enough for one more generation to see for themselves what the price tag of inaction really is.....

@McgowanHamish @JohnFBruno @abcnews Isn’t acidification important too? How much time does temperature alone buy?

Another example of detachment from reality; no understanding of scale of the basic meteorological factors that influence cloud cover and the impact on surface irradiance that would need to occur to lower water temperatures over the GBR. #AORG abc.net.au/news/2020-04-1… via @ABCNews

@McgowanHamish @abcnews Actually, very roughly, generalising from our hydrodynamic modelling. It’s about -0.035 degC SST per -W/m2 applied over 3-4 weeks, assuming the change in forcing was over the length of gbr marine park. Knock off ~20% if you only do 1/4 the area. 10W/m2 could make a big difference

Brightening clouds and coral larvae: study picks best Great Barrier Reef rescue ideas theguardian.com/environment/20…

We are proud to have helped steer the concept feasibility phase of the #ReefRestoration and #Adaptation Program with an amazing team of experts. The results of this rigorous and comprehensive study will inform the R&D phase and are now available: gbrrestoration.org/investment-cas…

@MichaelEMann I guess you could sit in those deck chairs and watch the reef disappear... If in the end this doesn’t help I doubt I will regret having tried. There is much we don’t know about aerosol - cloud interactions especially over the reef. So at the very least there is a lot to learn

Rearranging the deck chairs might help too... theguardian.com/environment/20…

@ProfTerryHughes More energy intensive, more difficult to generate the specific larger droplet size required en mass, but maybe possible. E.g. atmos-chem-phys.net/17/13071/2017/…

@ProfTerryHughes Also worth noting that if you can manage to generate droplets just the right size you don’t need to rely on clouds. Although we haven’t figured out how to do that just yet....

@ProfTerryHughes Yep more so some summers than others. This is why the modelling shows that if the clouds over the reef are found to be susceptible to brightening, it would have helped more in 16/17 then 15/16

@ProfMattEngland @ProfTerryHughes Sounds like opinion not confirmation to me. Matt, since you are an ocean modeller why don’t you take a look at the modelling reports? Pleased to receive feedback on the science, preliminary though it is.

@ProfTerryHughes Thanks for posting Terry - this looked like a very dodgy bandaid to me. Good to have that suspicion confirmed.

@peteirvine @Oliver_Geden @SCUonline Grr this is as bad as texting on an iPhone...

@peteirvine @Oliver_Geden @SCUonline Hi Pete, just back from the fiel so no paper just yet but it’s on it’s way. We have been in touch with UW folks, at the moment working on engineering the delivery technology cloud micro physics studies still a few years off

Just in time our team managed a world first trial of cloud brightening technology on the GBR before COVID-19 lockdowns. ⁦@SCUonline⁩ ⁦@ #covid-19 #rrap theguardian.com/environment/20…

@ronan_taylor67 No this was funded by the boosting coral abundance challenge run by the Qld Government with support of Federal Government
