Latest News 2 September 2024, The Conversation: ‘It’s time to give up on normal’: what winter’s weird weather means for the warm months ahead. Heavy winds struck south-east Australia over the weekend as a series of cold fronts moved across the continent. It followed a high fire danger in Sydney and other parts of New South Wales last week, and a fire in south-west Sydney that threatened homes. The severe weather rounds out a weird winter across Australia. The nation’s hottest ever winter temperature was recorded when Yampi Sound in Western Australia reached 41.6C on Tuesday. Elsewhere across Australia, winter temperatures have been way above average. We can look to the positives: spring flowers are blooming early, and people have donned t-shirts and hit the beach. But there’s a frightening undercurrent to this weather. Earth’s climate has become dangerously unstable, and it’s only a matter of time before we get the bad combination of hot and dry weather, strong winds and a spark. None of this should come as a surprise. The sooner we stop expecting Australia’s weather to be “normal”, the sooner we can prepare for life in a wild climate. The green is deceiving The landscape around Sydney – and in fact, across much of south-east Australia – is very green at the moment. That’s because we’ve had a couple of years of good rains which triggered an explosion of vegetation growth. The below NASA satellite image reveals the picture in stark detail. It’s certainly lush out there at the moment. But the problem with climate change is that weather conditions can turn on a dime. This August was a case in point. At month’s end, much of Australia was hit by a record-breaking heatwave and damaging winds – conditions that can dry out a green landscape with devastating efficiency, turning it into fuel for a bushfire. The dangerous fire weather that struck Sydney this week came as a surprise to many. But in reality, these abnormal conditions are the new normal. We must open our minds to this, if we want to be prepared. Read more here 21 August 2024, Climate Home News: In a world first, Grenada activates debt pause after Hurricane Beryl destruction. More creditors are agreeing to suspend debt payments in the wake of weather disasters, but experts say greater financial relief will be needed. As Hurricane Beryl swept through the Caribbean in early July, its deadly passage left a trail of destruction across the island nation of Grenada. Winds of up to 240 kilometres per hour flattened entire neighbourhoods and toppled power and communication lines, causing damage equivalent to a third of the country’s annual economic output, according to early government estimates. Many Grenadians cast their minds back 20 years when a similarly powerful storm – Hurricane Ivan – brought the island state to its knees, triggering a vicious circle of financial distress that eventually led to a debt default. But, unlike in 2004, officials this time could deploy a tool that has been widely discussed in climate circles to provide financial help in the wake of fierce storms: hurricane clauses built into its agreements with international creditors. Grenada last week became the first country in the world to use such a provision in a government bond which will allow it to postpone debt repayments to private investors, including US investment firms Franklin Templeton and T. Rowe Price. The move will save the Caribbean island nation a total of around $30 million in payments due this November and in May next year. While the money owed will be added to future bills, in the meantime the cash injection will help fund immediate recovery efforts and keep essential services like healthcare and education running, a senior official in Grenada’s Ministry of Finance told Climate Home. The government is now “in talks” about triggering similar clauses with other creditors. Fighting the debt trap. Grenada’s use of debt suspension clauses will be seen as a litmus test for their effectiveness in shoring up disaster-hit economies, as major international financial institutions like the World Bank promise to offer them more widely to climate-vulnerable countries.

Record breaking fossil fuel production, all time high greenhouse gas emissions and extreme temperatures. Like the proverbial frog in the heating pan of water, we refuse to respond to the climate and ecological crisis with any sense of urgency. Under such circumstances, claims from some that global warming can still be limited to no more than 1.5°C take on a surreal quality. For example, at the start of 2023’s international climate negotiations in Dubai, conference president, Sultan Al Jaber, boldly stated that 1.5°C was his goal and that his presidency would be guided by a “deep sense of urgency” to limit global temperatures to 1.5°C. He made such lofty promises while planning a massive increase in oil and gas production as CEO of the Abu Dhabi National Oil Company. We should not be surprised to see such behaviour from the head of a fossil fuel company. But Al Jaber is not an outlier. Scratch at the surface of almost any net zero pledge or policy that claims to be aligned with the 1.5°C goal of the landmark 2015 Paris agreement and you will reveal the same sort of reasoning: we can avoid dangerous climate change without actually doing what this demands – which is to rapidly reduce greenhouse gas emissions from industry, transport, energy (70% of total) and food systems (30% of total), while ramping up energy efficiency. A particularly instructive example is Amazon. In 2019 the company established a 2040 net zero target which was then verified by the UN Science Based Targets initiative (SBTi) which has been leading the charge in getting companies to establish climate targets compatible with the Paris agreement. But over the next four years Amazon’s emissions went up by 40%. Given this dismal performance, the SBTi was forced to act and removed Amazon and over 200 companies from its Corporate Net Zero Standard. This is also not surprising given that net zero and even the Paris agreement have been built around the perceived need to keep burning fossil fuels, at least in the short term. Not to do so would threaten economic growth, given that fossil fuels still supply over 80% of total global energy. The trillions of dollars of fossil fuel assets at risk with rapid decarbonisation have also served as powerful brakes on climate action. Overshoot: The way to understand this doublethink: that we can avoid dangerous climate change while continuing to burn fossil fuels – is that it relies on the concept of overshoot. The promise is that we can overshoot past any amount of warming, with the deployment of planetary-scale carbon dioxide removal dragging temperatures back down by the end of the century. This not only cripples any attempt to limit warming to 1.5°C, but risks catastrophic levels of climate change as it locks us in to energy and material-intensive solutions which for the most part exist only on paper. To argue that we can safely overshoot 1.5°C, or any amount of warming, is saying the quiet bit out loud: we simply don’t care about the increasing amount of suffering and deaths that will be caused while the recovery is worked on.

Australia’s south and east have seen freezing temperatures and wild weather this winter. At the same time, the continent as a whole – and the globe – have continued to warm. What’s going on? As ever, it’s hard to pinpoint a single cause for weather events. But a key player is likely an event unfolding high above Antarctica, which itself may have been triggered by a heatwave at surface level on the frozen continent. Here’s what’s happening – and what it might mean for the rest of this year’s weather. When the stratosphere heats up Our story begins in the cold air over Antarctica. July temperatures in the stratosphere, the layer of air stretching between altitudes of around 10 and 50 kilometres, are typically around –80°C. The winds are also very strong, averaging about 300 kilometres per hour in winter. These cold, fast winds loop around above the pole in what is called the stratospheric polar vortex. Occasionally, persistent high air pressure in the lower atmosphere can influence large-scale waves that extend around the globe and up into the stratosphere. There they cause the strong winds to slow down, and the air high above the pole to become much warmer than normal. In extreme situations the stratospheric winds can completely break down, in what is called a “sudden stratospheric warming” event. These events occur every few years in the northern hemisphere, but only one has ever been observed in the south, in 2002 (though another almost happened in 2019).

But it’s becoming increasingly necessary––this video digs into some of the ways people have come to accept it. Source: Holly Kaw! Do we drink recycled water in Australia? Depending on where you live, or where you’ve travelled, there’s a chance you’ve already drunk recycled water. Water recycling happens in other regions of Australia but the water is generally directed exclusively for irrigation or industrial use. Recycled water overseas FCA is an alliance of farmers and leaders in agriculture who are working with their peers, the wider sector and decision-makers to make sure Australia takes the actions necessary to address damage to our climate. FCA is determined to see farmers and agriculture get the support and investment it needs to adapt to a changing climate, as well as be part of the solution. Members are spread far and wide across the country: from the tropical north of Queensland to Tasmania, and from the wine growing regions of Western Australia right across to the sheep and cropping farms of New South Wales. Farmers for Climate Action is an associate member of the National Farmers Federation, and a member of the Climate Action Network Australia (CANA). We work closely with stakeholders within the agricultural and climate realms. Learn more about Farmers for Climate Action here 26 December 2016, Climate News Network. An internet tool is now available that helps to quantify and control farms’ greenhouse emissions released during the crop production cycle. It’s called the Cool Farm Tool (CFT) – an easy-to-use online calculator that helps farmers monitor their emissions of greenhouse gases. Agriculture accounts for about 15% of total global greenhouse gas emissions, though when fertiliser manufacture and use and the overall food processing sector are included in calculations, that figure is considerably higher. The land can also act as a vital carbon sink, soaking up or sequestering vast amounts of carbon: when soils are disturbed the carbon is released, adding to greenhouse gases in the atmosphere. The CFT was initially developed by researchers at the University of Aberdeen in the UK in partnership with Unilever and the Sustainable Food Lab. Now managed by a group including academics and food manufacturers called the Cool Farm Alliance, the CFT is free for farmers to download. Various details, including the crops being planted, soil types and pH levels (the relative acidity or alkalinity of the land), are entered into a series of boxes. Moisture levels, amounts and types of fertiliser used and general management details are also entered, along with information on quantities of diesel and electricity used in the cultivation and storage of crops and the fuel needed to transport goods on and off the farm. Read More here The Cool Farm Tool covers virtually all crops and livestock globally. One exception is for crops grown in non-soil media (e.g. greenhouses or hydroponically), but proxies can be used. The Tool is undergoing an update for livestock including new emission factors for feed, and improvements to the user interface. A project is also underway to improve ease of use and applicability of the Cool Farm Tool for many perennial and multi-year crops (coffee, tea, orchard crops, berries). Results from both projects are due in 2017.

Australia is extremely vulnerable to disruptions in food supply through extreme weather events. Climate change is the most challenging threat to food and water security between now and 2050 Water risks like stress and variable supply threaten everything from agriculture to industry to energy production. Already, 69 countries and one-quarter of the world’s cropland face high water stress. These challenges will likely become more severe as competition for water increases and climate change shifts precipitation patterns. The World Economic Forum identified global water crises as one of the top five global risks for businesses. Without tools to evaluate these risks and inform management plans, businesses’ bottom lines will suffer. Read More here UNEP: The real concern for the future, in the context of changing patterns of rainfall, is the decrease of run-off water which may put at risk large areas of arable land. The map shows how seriously this issue must be taken, while the forecast indicates that some of the richest arable regions (Europe, United States, parts of Brazil, southern Africa) are threatened with a significant reduction of run-off water, resulting in a lack of water for rain-fed agriculture and thus putting millions at risks. The accelerating changes in our global climate will undoubtedly cause major changes in the patterns of water cycle and geographical distribution, in the near future. Some regions will receive less precipitation, some more, and this will significantly affect agricultural activity. While some regions will see a reduction in arable land, others will have more suitable land for agriculture. It’s likely that certain types of agriculture will migrate and traditional areas for crops will change. In other words, climate change will alter the geography of traditional crop areas, which may impact on the world’s capacity to provide enough food for all. Since the 1990s, the scientific community has been warning about the rapidly changing climate, endeavouring to convince people to take urgent measures to mitigate the changes. These multiple warnings have been ignored until very recently, but the issue is now a priority with many international organizations. However, all reliable climate scenarios run by the IPCC and published in the fourth assessment reports show the following results: In other words, ongoing climate change will mean that the water supply for human communities will become more and more uncertain. The IPCC has stated that between 2000 and 2005 in the northern hemisphere, climate change accelerated faster than predicted, with the consequence that the water cycle could change in an unpredictable way, leading to the possibility of increases in extreme weather. The fear is that with all these changes, even if the quantity of water in the world does not change, the level of accessibility of the theoretically available water may significantly change. Source: UNEP Future Directions International highlights Australia’s challenge BOM water information and update sites 3 August 2015, The Conversation, The role of water in Australia’s uncertain future: If you live in an Australian city, there’s a good chance that your water comes from surface water such as streams, rivers and reservoirs filled by rainfall and runoff. If you live in Perth, much of your water (about 40%) comes from groundwater. But you might be surprised to know that a sizeable proportion of water in Australia came from recycling or desalination in 2013-14. 39% of Perth’s water came from desalination and 41% of Adelaide’s. All cities also used small portions of recycled water: Melbourne (4%), Sydney (7%), southeast Queensland (7%), and Canberra (8%). The Bureau of Meteorology recently released, for the first time, comprehensive national data on these “climate-resilient” water sources, through a new online portal provided as part of the Bureau’s Improving Water Information program. Climate-resilient water sources are those on which climate variability, such as variations in rainfall, temperature and drought, has little or no influence. The data set provides information on two of the most significant such sources: desalination and water recycling. The Climate Resilient Water Sources web portal is an interactive site providing comprehensive mapping and information of desalinated and recycled water sources for over 350 sites across Australia, both publicly and privately owned and operated. Users can access the portal, to search information on capacity, production, location and use of these alternative water sources across Australia. How many desalination and recycled water plants does Australia have? Below you can see the amount of desalinated and recycled water sourced for Australia’s cities in 2013–14 from the National Performance Report released in May 2015. From the Climate Resilient Water Source data we can also see which parts of Australia have the greatest climate resilient capacity compared to their sourced water (including surface, ground, recycled water and desalination). Western Australia has greater climate resilient capacity than its total water sourced in 2013–14, as you can see in the chart below: We can also see that more than 50% of reported production of recycled or desalinated water in 2012-13 (410,491 ML) was for urban use (residential, domestic, commercial, industrial, municipal). Read More here Improving Water Information: data, status and forecasts Australia’s variable climate drivers Weather and climate drivers: Floods, drought, and climate change are all driven by a number of processes in the atmosphere and oceans but the changes are driven at different timescales. The drivers shown in the map interact with each other and influence different parts of the continent to bring local weather and climate. The drivers include circulation patterns in the Pacific Ocean that bring El Niño conditions associated with drought in eastern Australia and La Niña conditions that are associated with floods. The Indian Ocean Dipole is a similar pattern in the Indian Ocean that can bring drought to south-west and south-east Australia, and the Southern Annular Mode are the major influences on rainfall (and thus runoff) in Australia. For more detail visit BOM here. Relatively small changes in rainfall are amplified to much larger changes in runoff and groundwater recharge, which make Australia’s water resources the most variable in the world. Water management is highly adapted to this variability, but the millennium drought in south-east Australia and the sharp drop in runoff in the South West of Western Australia since 1975 have tested the effectiveness of these adaptations. New measures are being introduced such as urban water supplies that are less dependent on runoff and the return of water to the environment to make it more sustainable. Climate change is occurring on top of that variability and in southern Australia it is likely to further reduce water resources. For the moderate climate change predicted to occur by 2030, the adaptation to droughts and floods can be effective, because the worst consequences are likely to be more intense droughts and less frequent but more intense floods. For further climate change, projected to occur by 2050 or 2070, the conditions of the millennium drought might become the average future water availability, which would have profound consequences for the way water is used and for ecosystems. The understanding of how climate influences water can help make water management more adaptable, such as through improved seasonal forecasts, and it can help communities plan how they will respond to reduced water availability in future. Source: CSIRO Water 7 climate chapter 3 from Water – Science & Solutions Report Understanding the ENSO Influence Source: BOM ENSO Wrap-up Groundwater use is increasing across Australia but the total use is difficult to estimate. Most groundwater is extracted by individual users and is rarely metered, and only a small fraction is managed through distribution networks. In 2004–05, licences for groundwater use were about 4700 GL/year, or 25% of the total amount of water consumed in Australia.2,3 Unlicensed use of groundwater – mainly for stock and domestic uses – is estimated to consume an additional 1100 GL/year.4 The amount of groundwater used is estimated to have almost doubled since the mid 1980s. Increased use of groundwater has been facilitated by recent drilling technologies and cheap submersible pumps that can lift water from considerable depths. In the drier parts of Australia, groundwater is the predominant water source because surface water resources are so scarce. Perth and Alice Springs, for example, rely on groundwater for about 80 and 100% of their water supply, respectively. When surface water resources become scarce, users turn to groundwater to meet their needs. Declines in surface water availability during the millennium drought in the southern Murray–Darling Basin led to a modest rise in groundwater use (1240 GL in 2000–01 to 1531 GL in 2007–08), but a sharp rise in the proportion of water supplied from groundwater (11% to 37%).5 Given the reliability of supply and convenience of self supply, the use of groundwater may not return to previous levels, even when surface water availability does. Many aquifers with high historical rates of use are showing symptoms of over-use, such as falling water tables and lower aquifer pressures and subsequent impacts on future use, groundwater salinity, river flows, and ecosystems. The level of over-use was not recognised for decades because of the lags inherent in large, flat, and slow moving groundwater systems. Remediation of these systems is expensive and difficult because salinity and ecological damage are hard to reverse, and because of the historical expectation of reliable water supplies. Inadvertent impacts of recent strong growth in groundwater use have not been felt yet and, given that the consequences of present use are in many cases still to be felt, some caution should be exercised around future groundwater development, by putting effective risk assessment and management processes in place.

Government, industry and the general public can use these products to inform decision-making and research about groundwater resources. Groundwater information products: A third of the world’s biggest groundwater basins are in distress 16 June 2015, Two new studies led by UC Irvine using data from NASA Gravity Recovery and Climate Experiment satellites show that civilization is rapidly draining some of its largest groundwater basins, yet there is little to no accurate data about how much water remains in them. The result is that significant segments of Earth’s population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings appear today in Water Resources Research. “Available physical and chemical measurements are simply insufficient,” said UCI professor and principal investigator Jay Famiglietti, who is also the senior water scientist at NASA’s Jet Propulsion Laboratory. “Given how quickly we are consuming the world’s groundwater reserves, we need a coordinated global effort to determine how much is left.” The studies are the first to characterize groundwater losses via data from space, using readings generated by NASA’s twin GRACE satellites that measure dips and bumps in Earth’s gravity, which is affected by the weight of water. For the first paper, researchers examined the planet’s 37 largest aquifers between 2003 and 2013. The eight worst off were classified as overstressed, with nearly no natural replenishment to offset usage. Another five aquifers were found, in descending order, to be extremely or highly stressed, depending upon the level of replenishment in each — still in trouble but with some water flowing back into them. The most overburdened are in the world’s driest areas, which draw heavily on underground water. Climate change and population growth are expected to intensify the problem.

Source: Virtual Water, University of British Columbia Australia and the Global Food and Water Crisis Source: Water Scarcity and Future Challenges for Food Production Future Directions International preamble from their webpage regarding “Australia’s role in solving future global food and water crises”: Food and water insecurity are among the most formidable challenges facing the world. The potential for food or water crises to manifest between now and 2050 is high. If such events were to occur, they would lead to rising poverty levels, slowing growth and development, and widespread instability and conflict. Australia’s greatest responsibility and opportunity in the 21st century is to help feed a hungry world. Mobilisation of political will and an overhaul of the existing global food systems are critical to avert crises. To access Future Directions Reports: “Food and Water Security: Our Global Challenge”; The Forgotten Resource: Groundwater in Australia 28 May 2015, Future Directions International: Urban agriculture is becoming an increasingly prominent topic in discussions on food security in Australia. More than 90 per cent of Australia’s population lives in urban centres and depends on a decreasing agricultural workforce to meet increasing food demand. Long food supply chains, although economically efficient, lead to poor nutritional and environmental outcomes for society. The re-localisation of food production will support and enhance Australia’s food system and has the potential to increase access to nutritious, affordable food for the most vulnerable. Australia produces enough food to feed 60 million people, yet economic barriers leave an estimated 2 million Australians dependent on food relief annually. Foodbank Australia is reportedly struggling to meet demand; it turns away as many as 60,000 people each month due to a shortage of food. To enhance food security, efforts need to be focussed on overcoming the increasingly volatile food prices that are expected to occur as a result of increased production and energy costs and the effects of climate change. There is a strong consensus amongst academics and policy makers that urban agriculture is a viable means of increasing domestic food security. Urban agriculture has assisted communities in both developed and developing nations to cope with food insecurity, by ensuring local availability of nutritional and affordable food. Greater support, however, is required from the Federal, State and Local governments, to ensure that benefits can be realised within Australian cities. Read More here

Zero Carbon Australia Discussion Paper: Land Use: Agriculture and Forestry: Emissions in the agriculture and forestry sectors in Australia are high and growing. The UNFCCC National Inventory Report suggests that sources of land use emissions, such as land clearing for agriculture and enteric (intestinal) fermentation from digestive processes in livestock, contribute 15% of national emissions. Australia’s land use sector is in a unique position to mitigate (reduce) climate impacts and take a leading role in addressing climate change. Agriculture and forestry are the only sectors of the Australian economy that can draw carbon dioxide out of the atmosphere by sequestering it in growing plants and in the soil. The agriculture and forestry sectors can mitigate climate impacts on the land, bringing prosperity to rural areas in the process. The Zero Carbon Australia Land Use report explores how this can be done.
