Australian Prime Minister Scott Morrison is back trying to pretend the politically inconvenient fact of climate change is not occurring in the leadup to the 2022 federal election


Australian Bureau of Meteorology



On 5 November 2021 Australian Prime Minister & Liberal MP for Cook (NSW) Scott Morrison issued a lengthy media statement which ended with these three lines:


High Risk Weather Events

National Cabinet received a briefing from Emergency Management Australia on the 2021-22 High Risk Weather Season, and noted that a La Niña watch has been issued in 2021.”


NOTE: Emergency Management Australia falls within the Dept. of Home Affairs. It organises the National Catastrophic Natural Disaster Plan (NATCATDISPLAN) last updated in 2017, republished in 2020.


To be honest I did not think why those three lines had been tacked on at the end of a statement which covered Vaccination and Booster Plans, Ensuring COVID-19 Outbreak Readiness for Indigenous Communities, National Plan to Transition Australia’s COVID-19 Response, Living with COVID-19 - Revised Test, Trace, Isolate and Quarantine (TTIQ) and Public Health and Social Measures (PHSMs), Living with COVID-19 - Health System Capacity, Borders and International Travel, along with this live link Doherty Institute COVID-19 modelling: 2nd tranche [PDF 651 KB].


At most all I thought was ‘Oh yes, the La Niña ALERT. North Coast Voices covered that in October and November posts'.


What I didn’t know and the Prime Minister did, was that the Australian Bureau of Meteorology had put together a rather more pointed weather outlook and forecast in power point form, which brought together the dry technical language on its website & its YouTube videos in a way that clearly showed where climate change had landed us all in 2021-22.


It must have been as obvious to the Prime Minister, as it was to me once I sighted segments of that presentation, that this was not information that a notorious climate change trivialising federal government would want to highlight going into an election year. However, as a slippery, slithering game player who is always looking for plausible deniability, those three brief lines would allow Morrison to say 'but I told Australia about it!' if a journalist thought to ask.


Here are a selection of slides from that presentation courtesy of Senator Rex Patrick’s Twitter account:

The Guardian, 4 December 2021:


Tropical cyclones and flooding are set to pummel Australia over summer, national cabinet documents reveal.


The Bureau of Meteorology briefed the meeting of premiers, chief ministers and the prime minister on 5 November about the high-risk weather facing the nation until April.


National cabinet documents are usually kept secret, but South Australian senator Rex Patrick obtained these under freedom-of-information laws.


Last week Patrick, the Labor leader, Anthony Albanese, and One Nation’s Malcolm Roberts all launched attacks on the prime minister’s department for its secrecy. There is a broader legal question about whether national cabinet is entitled to the cabinet-in-confidence protection, with critics saying that merely calling it a cabinet does not actually make it one.


The bureau director general, Joe Buffone, presented Emergency Management Australia’s 2021-22 High Risk Weather Season briefing.


The PowerPoint presentation shows there are increased chances of widespread flooding, coastal flooding and erosion, tropical cyclones and marine heatwaves, compared with average summers and early autumns.


There is a lower chance of drought and dust.


The overall risk of severe storms is on par with other years, while parts of Queensland and NSW have an increased risk of bushfire, and there is a higher chance of heatwaves than usual.


Warm waters mean slightly above average tropical cyclone numbers – the average is 11 per season.


La Niña means the weather is likely to be cooler, wetter and stormier. Areas that had above-average rainfall during spring, and therefore more grass, could lead to a heightened grassfire risk, while parts of the east coast will have a lower risk – because the 2019-20 fires reduced fuel loads.


The bureau’s presentation was prepared with publicly available information.


Patrick said the prime minister, Scott Morrison, should have released the documents when he released a media statement about the national cabinet meeting. That statement focused almost entirely on Covid, with a single line about the briefing.


That line prompted Patrick to make the FOI request to the Department of Home Affairs…….


And so it starts.

Tropical Cyclone Uesi predicted to cause damaging seas along Australia's east coast as it weakens


Tropical Cyclone Uesi at Category Two level, Monday 10 February 2020


The Tropical Cyclone Warning Centre Port Vila, Vanuatu, has this particular cyclone tracking south west towards south-east Qld and the NSW North Coast as it weakens.

Weatherzone reported on 10 February 2020 that:

At this stage, there is a fair bit of uncertainty around the movement of this system from Thursday onwards, with a range of plausible scenarios. 
Some forecast models suggest that Uesi will move towards the southwest on Thursday and Friday, which would allow it to move closer to Australia's east coast towards the end of the week. If this happens, the remnants of Tropical Cyclone Uesi, most likely in the form of an extra-tropical cyclone, could cause direct impacts in eastern NSW or southeast Queensland. These impacts could include large and dangerous surf, strong winds and heavy rain. It's worth pointing out that dangerous wind and rain would only occur if the system gets close enough to the coast, while powerful surf can reach Australia even if the system stays well offshore.


The Weekly Times, 11 February 2020

According to the Fiji Meteorological Service, which is tracking Uesi, its current route should take it in a south-westerly direction towards the coasts of both New South Wales and Queensland. It could enter Australian waters as early as Thursday.

The Australian Bureau of Meteorology also says there is a moderate chance the cyclone could turn southwest towards Australia on Thursday — giving odds of between 20%-50% the storm will enter the Coral Sea’s eastern region.

Issued at 2:37 am AEDT Thursday 13 February 2020. 
Refer to Tropical Cyclone Advice Number 7.

ABC News, 12 February 2020:

Tropical Cyclone Uesi could cause more havoc across the NSW coastline later this week, bringing swells of up to 5 metres. 

The news comes as the clean-up continues after the weekend's wild weather. 

The category three cyclone, which is passing north-east of New Caledonia, will track south-west towards the Tasman Sea and could cause increased swells, wind and rainfall as early as Thursday. 

ABC News weather journalist Graham Creed said the cyclone was expected to come closest to the coast on Friday and Saturday. 

"This may produce large swells, which combined with king tides may cause issues for beach erosion, as well as prolong the potential for locally heavy rainfall in showers and thunderstorms," he said....

The forecast at this stage is for swells of about 2 to 3 metres starting on the north NSW coast on Thursday and increasing to 3 to 5 metres on Friday....

By 8pm this evening, Thursday 13 February Cyclone Uesi will have dropped to a tropical low (while possibly maintaining an intensity equivilant to a Category 2 tropical cyclone) and is expected to sit less than 600km to the east of Tweed Heads as the crow flies.

At 2am Friday 14 February 2020 the tropical low is expected to be sitting further south less than 600km to the east of Moonee Beach.

Late Friday night the low will continue to track south before veering further away from the NSW coastline on Saturday.
