There are 19 large dams on NSW regional regulated rivers and hundreds of smaller dams, reservoirs & weirs associated with a mix of environmental use, off-farm agricultural and urban water storage on other rivers.

Across the seven local government areas in the Northern Rivers region water storage locations include:

Toonumbar Dam

Rocky Creek Dam

Clarrie Hall Dam

Emmigrant Creek Dam

Korrumbyn Creek Dam

Shannon Creek Dam

Bray Park weir

Tyalgum weir

Mullumbimby Power Station weir

Jambour weir

Kyogle weir

Nymboida weir

Rushforth Road 100ML Reservoir.

Tweed Shire Council is strongly alerting its residents and ratepayers as to the current situation and what may lie ahead.

The Echo, 27 September 2023:

Following the devastating floods of 2022 we are back to dry weather. The Bureau of Meteorology (BOM) has declared an El Nino weather pattern and it has predicted that there will be less-than-average rainfall in the Northern Rivers this year. Tweed Council is reminding residents and visitors that it is important to save water as we head into dry weather.

‘Without significant rain, the Tweed will head into water restrictions, with restrictions for Tyalgum looking likely in the next few weeks,’ said Tweed Shire Council’s (TSC) water and wastewater business and assets manager Michael Wraight.

‘We source our water from the Tweed River at Bray Park and Uki, plus the Oxley River at Tyalgum. The river flows are down and the weir pools at Bray Park and Tyalgum are drying up.

‘While Clarrie Hall Dam is currently sitting at 98 per cent capacity, it will now drop about 1 to 1.5 per cent, per week, as we start releasing water to supply the Bray Park Weir – the source of water for most of the Shire.

‘We will trigger level 1 water restrictions when the Clarrie Hall Dam level drops to 85 per cent.

‘Restrictions at Tyalgum will be introduced sooner. The flow of the Oxley River at Tyalgum is down to a trickle and the weir pool there is dropping fast.’

The other shoe has finally dropped - El Niño has been declared by Australian Bureau of Meteorology

Central and eastern Pacific sea surface temperatures (SSTs) currently exceed El Niño thresholds. International climate models suggest some further warming of the central and eastern tropical Pacific Ocean is likely. All surveyed models indicate SSTs will remain above El Niño thresholds until at least the end of the 2023–24 southern hemisphere summer.

Bureau long-range forecasts are for SSTs up to 2.5 °C warmer than average off eastern Tasmania and in the eastern Tasman Sea from October to the end of 2023.

Australian Bureau of Meteorology, 19 September 2023:

ElNiño and positive Indian Ocean Dipole underway

An El Niño and a positive IOD are underway.

The declaration of these events, and their concurrence over spring, reinforces the Bureau's long-range rainfall and temperature forecasts, which continue to predict warmer and drier conditions for much of Australia over the next three months. The confirmation of an established El Niño increases the likelihood that the event will be sustained through the summer period.

Oceanic indicators firmly exhibit an El Niño state. Central and eastern Pacific sea surface temperatures (SSTs) continue to exceed El Niño thresholds. Models indicate further warming of the central to eastern Pacific is likely.

Broadscale pressure patterns over the tropical Pacific reflect El Niño, with the 90-day Southern Oscillation Index (SOI) at −7.7. Recent trade wind strength has been generally close to average, but was slightly weaker than average across the tropical Pacific in August 2023 for the first time since January 2020.

Overall, there are signs that the atmosphere is responding to the pattern of SSTs in the tropical Pacific and coupling of the ocean and atmosphere has started to occur. This coupling is a characteristic of an El Niño event and is what strengthens and sustains an event for an extended period. Climate models indicate this El Niño is likely to persist until at least the end of February. El Niño typically leads to reduced spring and early summer rainfall for eastern Australia, and warmer days for the southern two-thirds of the country.

A positive Indian Ocean Dipole is underway. The Indian Ocean Dipole (IOD) index is +1.25 °C for week ending 17 September. This is its fifth week above the positive IOD threshold (+0.40 °C). The longevity of this trend, combined with the strength of the dipole being observed and forecast, indicate a positive IOD event is underway. All models predict this positive IOD will persist to at least the end of spring. A positive IOD typically leads to reduced spring rainfall for central and south-east Australia.

When a positive IOD and El Niño occur together, their drying effect is typically stronger and more widespread across Australia.

The Madden–Julian Oscillation (MJO) is currently weak and is forecast to remain weak over the coming week.

The Southern Annular Mode (SAM) index is currently negative and is expected to remain negative for at least the coming week, before a possible return to neutral late in September. During spring, a negative SAM is associated with decreased rainfall across parts of the east in both NSW and Victoria, and increased rainfall over western Tasmania.

The long-rangeforecast for Australia indicates warmer and drier than average conditions are likely across most of southern and eastern Australia from October to December. The Bureau's climate model takes into account all influences from the oceans and atmosphere when generating its long-range forecasts.

Global warming

Global warming continues to influence Australian and global climate. Global sea surface temperatures (SSTs) were warmest on record for their respective months during April to August 2023. August 2023 SSTs were also the warmest globally for any month since observational records began in 1850. July and August 2023 were also respectively the hottest and second-hottest months globally in terms of 2-metre air temperature.

Australia’s climate has warmed by an average of 1.48 ± 0.23 °C since national records began in 1910. There has also been a trend towards a greater proportion of rainfall from high intensity, short duration rainfall events, especially across northern Australia. Southern Australia has seen a reduction, by 10 to 20%, in cool season (April to October) rainfall in recent decades. This is due to a combination of natural variability on decadal timescales and changes in large-scale circulation caused by an increase in greenhouse gas emissions.

^^^^^^^^^^^^^^^^^^^^

Australia and the world are fast running out of time to limit negative impacts of climate change to spans of multiple generations rather than millennia

 

The United Nations website is very clear about what has been agreed at an international level concerning the global response required to limit the Earth’s global warming to an average 1.5°C, thereby limiting the negative impacts of climate change in intensity and time span – hopefully to spans of multiple generations rather than millennia.

The Paris Agreement is a legally binding international treaty on climate change. It was adopted by 196 Parties at the UN Climate Change Conference (COP21) in Paris, France, on 12 December 2015. It entered into force on 4 November 2016.

Its overarching goal is to hold “the increase in the global average temperature to well below 2°C above pre-industrial levels” and pursue efforts “to limit the temperature increase to 1.5°C above pre-industrial levels.”

Australia is a party to the 2015 Paris Agreement, effective 4 November 2016.

However, in recent years, world leaders have stressed the need to limit global warming to 1.5°C by the end of this century.

That’s because the UN’s Intergovernmental Panel on Climate Change indicates that crossing the 1.5°C threshold risks unleashing far more severe climate change impacts, including more frequent and severe droughts, heatwaves and rainfall.

To limit global warming to 1.5°C, greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030.

All those nations which entered into the Paris Agreement agreed to participate in the global attempt to reduce the world’s greenhouse gas emission by establishing firm undertakings in Nationally Determined Contributions (NDCs).

In their NDCs, countries communicate actions they will take to reduce their greenhouse gas emissions in order to reach the goals of the Paris Agreement. Countries also communicate in their NDCs actions they will take to build resilience to adapt to the impacts of climate change.

Australia submitted its first NDC to the United Nations Framework Convention on Climate Change (UNFCC) in 2015 and updated that version of the NDC in 2022. This update commits Australia to reducing its emissions to 43% below 2005 levels by 2030. It should be noted that in 2005 Australia’s total national greenhouse gas emissions of 559.1 million tonnes of carbon equivalent gases (MT CO²-e) was already 102.2% of its 1990 annual total of 515.9 MT CO²-e.

It could be said that even now our national reduction of greenhouse gas emissions is sluggish at best.

"For the year to June [2023], according to the preliminary numbers from the government’s latest national greenhouse gas inventory, emissions were 4.1 million tonnes above those for the corresponding period the previous year." [The Saturday Paper, 08.09.23]

 

In the year to December 2015 Australia’s “annual unadjusted” greenhouse gas emissions stood at 529.2 MT CO²-e. An artificially constructed figure because per government policy it excluded emissions from from land use, land use change and forestry. These excluded emissions would have possibly added more than 1.0 MT CO²-e bringing the national annual total to over 30 MT CO²-e in 2015.

By year to December 2022 Australia’s “actual annual” greenhouse gas emissions were recorded as 463.9 MT CO²-e. A figure arrived at by an alleged fall in emissions from land use, land use change and forestry of est. -13.6 MT CO²-e due to professed reductions in land clearing and native forest harvesting, increases in plantations and native vegetation, and improvements in soil carbon. NOTE: By year to December 2022 each person in Australia was estimated to be responsible for 17.8 tonnes CO²-e of that year’s greenhouse gas emissions total.

What Australian governments and industries has effected was a paltry national greenhouse gas emissions change of est.

-65.3 MT CO²-e spread over eight years – an average of 8.1. Or est. -95.2 MT CO²-e spread over 17 years – an average of 5.6 MT CO²-e per annum. And that change was to a significant degree on the back of the adoption of rooftop renewable energy by the general population which in the year to December 2022 was contributing to an electricity sector emissions reduction of 5.5 MT CO²-e, according to the Dept. of Climate Change, Energy, the Environment and Water.

Either way, leaving Australia with an urgent need to reduce greenhouse gas emissions by at least the promised -240.4 MT CO²-e within the next seven years. That’s roughly 34.3 MT CO²-e emissions we have to cease releasing into the air, waterways and oceans each and every year until 2030 to even have a chance at surviving as a nation and a functioning society beyond that year.

Creative accounting using offsets, hiding behind green washing propaganda, pushing hard decisions further down the track into the future, just won’t work. We need to immediately tighten polluting emissions regulations & abatement requirements, begin phasing out current unabated fossils greenhouse gas and, from this point in time where we stand right now, we must refuse all new or expanded proposals for fossil fuel extraction and use.

Australian industry and corporations both foreign and domestic are laughing in our faces and, federal & state governments appear all but frozen into inaction by the magnitude of the climate crisis before us. There will be no heroes coming down from the mountains to save us, no ships arriving to sail us all to as yet undiscovered safety, no divine miracles falling from the skies.

Australia’s estimated resident population stood at 26,268,359 men, women and children in December 2022 according to the Australian Bureau of Statistics. 

An estimated 21,461,249 of the resident population in 2022 were individuals 15 years of age and older.

By default theirs is the burden of stopping that 240.4 MT CO²-e of additional pollution entering earth’s atmosphere over Australia by 2030. That’s an extra 11.2 tonnes CO²-e per person averaging 1.6 tonne of carbon equivalent a year.

So how do we each attempt to shoulder this terrible burden? 

"Key finding 4: global emissions are not in line with modelled global mitigation pathways consistent with the temperature goal of the Paris Agreement, and there is a rapidly narrowing window to raise ambition and implement existing commitments in order to limit warming to 1.5 °C above pre-industrial levels."

“Climate breakdown has begun”

[U.N. Secretary-General Antonio Guterres, 6 September 2023]

NOAA Research, Global ocean roiled by marine heatwaves, with more on the way, 28 June 2023, excerpts:

This map depicts predicted marine heatwave conditions in September 2023 as generated by the Physical Sciences Laboratory’s experimental forecast model.

The experimental forecast, which tracks the NOAA Climate Prediction Center’s official outlook, is based on a large ensemble of climate model predictions spanning June 2023 through May 2024….

A marine heatwave is defined as a monthly regional sea surface temperature anomaly that ranks in the top 10% of warmest months compared with the 1991–2020 average. Long-term ocean warming trends also contribute to unusually high ocean temperatures, but even with the effects of long-term warming removed, models predict 25% of the global ocean will experience sharp upward departures from more recent conditions by September…..

In this scenario it appears that the Southern Ocean waters are within a probability range of between 60-80 per cent for the occurrence of marine heatwave which might have also lead to a rise in Antarctic sea surface temperatures.

Which begs the questions:

How will the over 60km long Halloween Crack in west Antarctica react to any additional stressors on the Brunt Ice Shelf?

Will the East Coast Ice Sheet which is said to contain four fifths of the world’s ice again lose ice shelf through iceberg calving as it did with C-37 (144 sq.km) & C-38 (415 sq. km) in March 2022?

Just how big are these Anthropocene Age icebergs going to grow – given many are the size of cities already? and

How long does the Southern Hemisphere have before sea level rise beyond the Antarctic Circle increases exponentially past millimetres into metres?

Antarctica’sBrunt Ice Shelf Finally Breaks

January 24, 2023

In February 2019, a rift spanning most of the Brunt Ice Shelf in Antarctica appeared ready to spawn an iceberg about twice the size of New York City. The question among scientists was not if the growing rift would finish traversing the shelf and break, but when? Now, nearly four years later, it has done just that.

According to the British Antarctic Survey (BAS), the break occurred late on January 22, 2023, and produced a new iceberg with an area of 1550 square kilometers (about 600 square miles). The U.S. National Ice Center has named it Iceberg A-81. The berg is visible in this image, acquired on January 24, 2023, with the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.

The glacial ice in the shelf flows away from the interior of Antarctica and floats on the eastern Weddell Sea. (For reference, the Antarctic Peninsula and its ice shelves are located on the opposite side of the Weddell.) The shelf has long been home to the British Antarctic Survey’s Halley Research Station, where scientists study Earth, atmospheric, and space weather processes. BAS reported that the station, which was relocated farther inland in 2016 as the chasm widened, was unaffected by the recent break.

January 12, 2021

The break occurred along a rift known as Chasm 1. This chasm started growing in the 1970s, followed by a period of dormancy, and then resumed growth in 2012. It continued to lengthen for almost a decade, extending by as much as 4 kilometers (2.5 miles) per year in early 2019. But even this growth spurt slowed. That is, until the 2022–2023 Antarctic summer when the chasm sped up and ultimately broke past the McDonald Ice Rumples—a submerged knob of bedrock that served as a pinning point for this part of the shelf. Several factors may have contributed to the completion of the break, including a lack of sea ice to help resist, or “push back,” against the stresses on the shelf ice in 2023.

The second image, acquired with the Operational Land Imager (OLI) on Landsat 8, shows the extent of Chasm 1 on January 12, 2021, about two years prior to the break. Notice several other cracks across the northeast part of the shelf. The “new crack” in that image ultimately separated in February 2021 and formed Iceberg A-74.

“The rapid formation of subsequent rifts—to long-standing Chasm 1 and 2—and recent calving to the northeast makes it clear that these shelf areas are dynamic with poorly understood stresses,” said Christopher Shuman, a University of Maryland, Baltimore County, glaciologist based at NASA’s Goddard Space Flight Center.

The breaking (calving) of icebergs from ice shelves is part of a natural, cyclical process of growth and decay at the limits of Earth’s ice sheets. As glacial ice flows from land and spreads out over the sea, shelf areas farthest from shore grow thinner. These areas are stressed by storms and tides and thin as they are melted from above or below, ultimately making them more prone to forming rifts and breaking away.

As for the “new” Brunt, it remains to be seen how the complex floating glacial ice responds to the most recent calving event. According to Shuman: “We have no solid idea what ‘normal’ really is for this unusual ice shelf.”

CLIMATE CHANGE STATE OF PLAY 2023: If this is to be Australia's Spring in 2023, what will Summer look like?

The Guardian, 1 September 2023:

On Thursday, the bureau said Australia’s spring would likely see hotter than average temperatures and lower than average rainfall – a combination that would increase the risk of bushfires.

Dr Masoud Edraki, a senior hydrologist at the bureau, said the record-high sea surface temperatures seen globally would continue to affect Australia’s weather.

“We know that a warmer climate does increase the risk of extreme weather including heatwaves and drought,” he said.

“We are already seeing longer fire seasons, and an increase in the number of dangerous fire weather days over most of Australia. We don’t know yet how global warming, and particularly the increased warmth in the oceans, is affecting our typical climate drivers.

“Our climate forecast model is consistent with the international climate forecasts that show Australia is trending dry and warm for the coming season, particularly in the south-west and much of south-eastern Australia.”

 

Australian Bureau of Meteorology (BOM), website excerpts retrieved 2 September 2023:

Global warming

Global warming continues to influence Australian and global climates. Global sea surface temperatures were highest on record for their respective months during April to July 2023, with July also being the equal-highest month on record (according to the ERA5 reanalysis). July 2023 was also the hottest month globally in terms of 2 metre air temperature.

Australia’s climate has warmed by an average of 1.47 ± 0.24 °C since national records began in 1910. There has also been a trend towards a greater proportion of rainfall from high intensity, short duration rainfall events, especially across northern Australia. Southern Australia has seen a reduction, by 10 to 20%, in cool season (April to October) rainfall in recent decades. This is due to a combination of natural variability on decadal timescales and changes in large-scale circulation caused by an increase in greenhouse gas emissions.

Warmer than median days and nights for most of Australia during spring

Issued: 31 August 2023

• For September, above median maximum temperatures are likely to very likely (60% to greater than 80% chance) across the southern two-thirds of Australia. Below median maximum temperatures are likely (60 to 80% chance) for the Queensland Gulf Country, and central and eastern NT.

• For September to November, above median maximum temperatures are very likely (greater than 80% chance) for almost all of Australia.

• For September to November, most of Australia is at least 2.5 times as likely to experience unusually high maximum temperatures (unusually high maximum temperatures equates to the warmest 20% of September to November periods from 1981 to 2018), with chances increasing to more than four times as likely for most of western and central WA and parts of the southeast.

• For September, above median minimum temperatures are likely to very likely (60% to greater than 80% chance) for Tasmania, Victoria, NSW on and east of the Great Dividing Range, the Southeast Coast of Queensland, and most of WA. Below median minimum temperatures are likely to very likely across most of the NT, the Kimberley and Northern Interior regions of WA, central and western Queensland, the far west of NSW and the North East Pastoral and Flinders districts of SA.

• For September to November, minimum temperatures are likely (60 to 80% chance) to be warmer than median for most of Australia excluding areas of north-east NT, northern Queensland, and south-east SA. Chances increase to very likely (greater than 80% chance) for Western Australia and parts of eastern Australia.

• For September to November, western and central areas of WA and areas on and east of the Great Dividing Range in NSW and Victoria are at least 3 times as likely to experience unusually high minimum temperatures (unusually high minimum temperatures equates to the warmest 20% of September to November periods from 1981 to 2018), with chances increasing to more than four times as likely for parts of central WA.

• Past accuracy of the September to November chance of above median maximum and minimum temperature long-range forecasts has been high to very high across all of Australia.

BOM: Max temperature - The chance of above median max temperature for September to November

With regard to rainfall:

For September to November, below median rainfall is likely to very likely (60% to greater than 80% chance) for most of Australia.

Later than usual rainfall onset likely for most of northern Australia

A later than usual northern rainfall onset for the 2023–24 season is likely for most of northern Australia.

Most of northern Australia excluding interior parts of Western Australia has a 60 to 70% chance of a later than usual rainfall onset. This increases to a greater than 70% chance for northern and eastern parts of the NT and Queensland, as well as along the Gascoyne Coast in WA.

The northern rainfall onset outlook gives an indication of whether the first significant rains after 1 September are likely to be earlier or later than their median date (based on historical observations, 1981–2018). View median onset dates here.

This is the final Northern Rainfall Outlook for the 2023 to 2024 season.

NOTE: The long-range forecast is influenced by several factors, including likely El Niño development and positive Indian Ocean Dipole development, and record warm oceans globally.

El Niño Alert continues, positive IOD likely for spring

The Bureau's El Niño Alert continues, with El Niño development likely during spring. When El Niño Alert criteria have been met in the past, an El Niño event has developed around 70% of the time.

Sea surface temperatures (SSTs) in the tropical Pacific are exceeding El Niño thresholds and have continued to warm slightly over the last fortnight. Climate models indicate further warming of the central to eastern Pacific is likely, with SSTs remaining above El Niño thresholds until at least early 2024.

Drought: Rainfall deficiencies and water availability

4 August 2023

• July rainfall for Australia overall was 1% above the 1961–1990 average.

• Rainfall for July was below average for southern two thirds of Western Australia, most of South Australia, eastern New South Wales, Victoria and eastern Tasmania and above average for much of the northern half of Australia.

• For the period commencing May 2023, large areas of severe rainfall deficiency (totals in the lowest 5% of historic observations since 1900) have emerged across much of the south-west half of Western Australia, and much of the east coast of New South Wales.

• For the period commencing December 2022, areas experiencing serious deficiencies (totals in the lowest 10% of observations since 1900) include parts of southern Queensland, parts of the north-eastern quarter of New South Wales and areas within the south-west of Western Australia.

• Soil moisture was below average (in the lowest 30% of all observations since 1900), across a wide band of south-west Western Australia into western South Australia, and parts of eastern Australia, particularly Wide Bay and Burnett in Queensland and along coastal New South Wales into far east Victoria.

• Low stream flows were observed mostly at sites in the west of Western Australia, areas of eastern coastal New South Wales and south-east Queensland, and scattered sites in the north of the Murray–Darling Basin.

• Storage levels remain low in some parts of south and central Queensland, eastern and southern parts of New South Wales, central Tasmania, and urban areas of Perth.

• For August to October, below median rainfall is likely to very likely (60% to greater than 80% chance) for much of Australia.

Seasonal Bushfire Outlook: Spring 2023

23 August 2023

Australia's climate influences have shifted significantly since last spring, with above average temperatures and below average rainfall expected for almost the entire country for the coming season. Many regions have also seen increased fuel growth due to above average rainfall throughout recent La Niña years, which is contributing to increased risk of bushfire across locations in Australia during the spring 2023.

Increased risk of fire is expected for regions in Queensland, NSW, Victoria, SA and NT. Communities in these regions are urged to prepare for bushfire and monitor local conditions.

Australia's climate influences have shifted significantly since last spring. Following above average rainfall experienced during consecutive La Niña years, the Bureau of Meteorology predicts a switch to higher chances of above average temperatures and below average rainfall for almost the entire country.

Recent rainfall means many regions have also seen increased fuel growth, which is contributing to increased risk of bushfire for many regions of Australia during the spring season.
