Hey everyone and welcome back. So that 0:02 2030 unlivable deadline, is it legit or 0:05 is it more complicated? Well, it's 0:08 definitely more complicated. While the 0:10 idea of entire major AI cities becoming 0:12 completely uninhabitable in just a few 0:14 years isn't quite what the main body of 0:16 scientific research is screaming from 0:18 the rooftops. The warnings are loud and 0:20 clear. Our cities are facing some huge, 0:23 and I mean colossal, challenges from 0:25 climate change. We're not talking about 0:27 some distant maybe in the future thing, 0:29 we're talking about now and the changes 0:31 are 0:32 accelerating. So, what are we really up 0:34 against? Instead of just saying 0:36 unlivable, let's break down the specific 0:38 pressures that scientists are pointing 0:40 to. And trust me, the evidence is there 0:43 and it's coming from the big guns. 0:45 Organizations like Australia's own CCO 0:47 Commonwealth Scientific and Industrial 0:49 Research Organization and the Bureau of 0:51 Meteorology, BOM, as well as global 0:53 bodies like the Intergovernmental Panel 0:55 on Climate Change, IPCC. These aren't 0:58 just opinions. This is based on decades 1:00 of research and climate modeling. First 1:03 up, let's talk extreme heat. Yeah, 1:05 Aussie summers are famously hot, right? 1:07 But what we're seeing and what 1:08 scientists have been documenting is an 1:10 increase in the frequency, intensity, 1:12 and duration of heat waves. The CZ state 1:15 of the climate reports, for instance, 1:17 highlight that Australia has warmed by 1:19 over 1.4° C since 1910, leading to more 1:23 extreme heat days. Think about cities 1:25 like Perth, Adelaide, and even parts of 1:27 Sydney and Melbourne. A 2024 study 1:30 highlighted in technology networks 1:32 mentioned that heatwave related deaths 1:33 in Australia have already risen due to 1:35 climate change and city dwellers, 1:37 especially in areas with less green 1:39 space, the urban heat islands are 1:42 particularly vulnerable. Imagine 1:44 consecutive days over 40° C or even 1:47 nudging 50° C in some inland urban 1:49 areas. That doesn't just make life 1:51 uncomfortable. It's a serious health 1:53 risk, especially for the vulnerable. It 1:55 strains our power grids. Everyone 1:57 blasting the AC impacts outdoor work and 2:00 can even buckle infrastructure. Are 2:02 these cities unlivable? Not entirely by 2:05 2030 perhaps, but the livability score 2:08 definitely takes a massive hit during 2:09 these increasingly common events. Then 2:12 there's water security. This is a big 2:14 one for the driest inhabited continent 2:16 on Earth. The IPCC's sixth assessment 2:19 report has specific sections on 2:21 Australasia, noting that southern and 2:23 eastern Australia are projected to 2:25 experience reduced rainfall and 2:26 increased evaporation. This directly 2:28 impacts the water supplies for major 2:30 cities. CER research has also pointed to 2:33 declining stream flow in catchments for 2:34 cities like Melbourne and those in 2:36 southwestern Australia. Places like 2:38 Perth have already invested heavily in 2:40 deselination because their traditional 2:42 water sources are under so much stress. 2:44 And it's not just about less rain. It's 2:46 about when it rains. More intense 2:48 downpours, but longer dry spells in 2:50 between. That's a recipe for both floods 2:53 and droughts, sometimes in cruel 2:55 succession. Add a growing population to 2:57 the mix, and you can see why water wars 2:59 isn't just a sci-fi trope, it's a 3:01 looming concern. Next, the one that 3:04 haunts our summers, bushfires. The black 3:06 summer of 3:07 2019-2020 is seared into our national 3:10 memory. And the science, the BOM and CC 3:13 clearly state that climate change is 3:15 exacerbating fire weather conditions. 3:16 Hotter, drier periods mean more fuel and 3:19 more days with extreme fire danger. 3:21 Cities that are on the Sojinton urban 3:23 bushland interface. Think parts of 3:25 Sydney, the Adelaide Hills, outskirts of 3:27 Cber and even some areas near Perth and 3:29 Brisbane are increasingly at risk. It's 3:32 not just the fires themselves, but the 3:34 smoke pollution that can blanket cities 3:35 for weeks causing widespread respiratory 3:38 problems. Can you call a city truly 3:40 livable when you can't safely breathe 3:41 the air for a significant chunk of the 3:43 year? That's a genuine question many are 3:45 starting to ask. And for our coastal 3:48 cities, which is, let's face it, most of 3:51 our major population centers, their sea 3:53 level rise and coastal inundation, sound 3:55 of gentle waves than a more aggressive 3:57 crashing wave. The CZ research on sea 4:00 level rise points out that global mean 4:02 sea level has risen by about 25 sea air 4:04 since 1,80 with half of that since 1970. 4:08 and the rate is accelerating. This means 4:10 increased coastal erosion, more frequent 4:12 and extensive flooding during high tides 4:14 and storm surges. Think about low-lying 4:17 areas in Sydney, Melbourne's Docklands, 4:19 the Gold Coast, Brisbane's Riverside 4:21 suburbs, and parts of Hobart and 4:22 Adelaide. It's not just about beaches 4:24 disappearing. It's about critical 4:26 infrastructure, roads, railways, ports, 4:28 and even homes and businesses being 4:31 threatened. Some projections show that 4:33 by 2050 or 2,100 without serious 4:36 intervention, parts of these cities 4:38 could be regularly inundated. 2030 might 4:41 be too soon for widespread abandonment, 4:43 but the planning for managed retreat or 4:45 massive coastal defenses needs to be 4:46 happening now. Okay, that was a heavy 4:49 dose of reality and it's easy to feel a 4:52 bit hopeless, right? But here's the 4:54 thing. Just because the challenges are 4:55 immense doesn't mean nothing is being 4:57 done. This is where we talk about the 4:59 antithesis, the response to these 5:01 threats. Many of the official reports 5:04 like those from the Department of 5:05 Climate Change, Energy, the Environment, 5:07 and Water DCC outline national 5:09 strategies for climate resilience and 5:11 adaptation. But what does that look like 5:13 on the ground? Well, for heat, cities 5:16 are exploring options like increasing 5:18 urban greening, more trees, parks, green 5:20 roofs to combat the urban heat island 5:22 effect. Some are looking at cool 5:24 pavement technologies. And there's a big 5:26 push for better building design and 5:28 public awareness campaigns. Think about 5:30 Melbourne's urban forest strategy or 5:32 Sydney's plans to increase canopy cover. 5:34 These aren't just about making the city 5:36 look nicer. They're vital for cooling. 5:39 For water security, it's a multi-pronged 5:41 approach. Perth has been a leader in 5:43 disselination and large-scale water 5:45 recycling. Other cities are focusing on 5:47 water sensitive urban design, rainwater 5:49 harvesting, and yes, those sometimes 5:52 unpopular water restrictions during 5:53 droughts. There's a huge investment in 5:56 more efficient irrigation for 5:57 agriculture, which uses a lot of our 5:59 water to free up resources for urban 6:01 areas. The Australian Water Association 6:04 often features innovations in smart 6:05 water management. When it comes to bush 6:08 fires, it's about improved forecasting, 6:10 better land management practices, 6:12 including indigenous fire management 6:14 techniques, stricter building codes in 6:16 at risk areas, and well-unded emergency 6:18 services. But it's also about tough 6:20 conversations about where we build and 6:22 whether some areas are simply too risky. 6:25 And for sea level rise, we're seeing a 6:27 mix of strategies. Some areas are 6:29 investing in seaw walls and other 6:31 coastal defenses. Others are looking at 6:33 restoring natural coastal habitats like 6:35 mangroves and salt marshes which act as 6:37 natural buffers. And in some highly 6:39 vulnerable spots, difficult discussions 6:41 about relocation or managed retreat are 6:44 beginning. Though this is often a last 6:45 resort, the climate council, an 6:47 independent body, has released reports 6:50 identifying vulnerable electorates, 6:52 sometimes pointing out that a percentage 6:53 of properties could become uninsurable 6:55 by 2030, which is a slightly different 6:58 but very impactful way of looking at 7:00 livability. For example, their 7:02 uninsurable nation report from 2022 7:05 identified places like Nits in Victoria 7:07 and Richmond in NSW as having high 7:10 percentages of properties at risk. This 7:12 isn't scientists saying the city is 7:14 unlivable, but that for individual 7:16 property owners, the financial viability 7:18 of living there could plummet. But 7:20 here's a critical point. Many argue that 7:22 these adaptation measures, while 7:24 essential, are often playing catch-up. 7:26 They're treating the symptoms. The 7:28 argument is that without aggressive 7:30 global action on reducing emissions, the 7:32 root cause of climate change, adaptation 7:34 can only tag us so far. It's like 7:36 bailing water out of a boat with a hole 7:38 in it. You need to plug the hole, too. 7:41 And some critics say current adaptation 7:43 plans aren't ambitious enough or that 7:45 funding is insufficient or that 7:47 implementation is too slow given the 7:49 urgency. They might point to the fact 7:51 that while we have national strategies, 7:53 the on ground action can be fragmented 7:55 across different states and local 7:57 councils. 7:58 So, where does this leave us? This is 8:00 the synthesis part. It's not a simple 8:02 case of cities will be fine versus we're 8:04 all doomed by 2030. The reality is far 8:07 more nuanced and frankly more 8:09 challenging. Australian cities are not 8:12 likely to be entirely abandoned. Ghost 8:14 towns by 2030 in the way some 8:16 sensationalist headlines might imply. 8:19 However, the quality of life and the 8:21 fundamental livability in many areas are 8:23 undeniably under serious threat and are 8:25 already being impacted. Some specific, 8:27 highly exposed communities or coastal 8:29 fringes might face extreme existential 8:31 choices much sooner than others. The 8:34 crucial understanding here is that 8:36 livability isn't a switch that just 8:37 flips off. It's a spectrum. And climate 8:40 change is pushing many of our urban 8:42 environments towards the more 8:43 challenging end of that spectrum. What 8:45 we're likely to see by 2030 and 8:48 certainly beyond are cities that are 8:50 more expensive to live in due to 8:51 insurance costs, adaptation measures, 8:53 higher prices for scarce resources like 8:56 water, cities with greater inequalities 8:58 as vulnerable populations often live in 9:00 the most at risk areas with the fewest 9:02 resources to adapt, and cities where our 9:04 lifestyle is increasingly dictated by 9:06 environmental extremes. Think more 9:08 indoor days due to heat or smoke, 9:10 restrictions on water use, and constant 9:12 anxiety about the next flood or fire. 9:15 What's becoming clear is that we need a 9:17 massive coordinated effort from 9:19 individuals making sustainable choices 9:21 to communities building local resilience 9:23 to governments implementing bold 9:25 science-led policies for both adaptation 9:27 and rapid decarbonization. The science 9:29 from CCRO, BOM, and the IPCC all 9:32 converges on this point. The window to 9:34 avoid the worst impacts is closing, but 9:37 decisive action can still make a huge 9:39 difference to the future livability of 9:41 our cities. So, this brings us to the 9:43 really big questions, the ones I want 9:45 you to chew on and discuss in the 9:47 comments below. One, when does a city or 9:50 part of a city actually become 9:52 unlivable? Is it when insurance becomes 9:54 unaffordable for most? When essential 9:56 services like water and power are no 9:58 longer reliable? When health impacts 10:00 become chronic for a large part of the 10:02 population? What's your personal tipping 10:04 point? Two, who should bear the primary 10:07 responsibility and cost for adapting our 10:10 cities? Is it individual homeowners, 10:12 local councils, state governments, the 10:14 federal government, or the industries 10:16 contributing most to emissions? How do 10:18 we make this equitable? Three, given 10:21 these projections, if you were planning 10:23 to buy property or raise a family in an 10:25 Australian city, how would this 10:27 information influence your decisions 10:28 about where to live or even if to live 10:30 in certain highly vulnerable areas? 10:33 Four, and perhaps the biggest one, are 10:36 we as a society truly grasping the scale 10:38 and urgency of these threats? Or is 10:40 there still a sense of it won't happen 10:41 to me or technology will save us at the 10:43 last minute? What will it take to 10:45 galvanize the level of action that the 10:47 science says is necessary? This isn't 10:49 just about abstract scientific data. 10:51 It's about our future, our kids' future, 10:54 and the very nature of life in 10:55 Australia. It's a tough conversation, 10:57 but it's one we absolutely need to keep 10:59 having. All right, that's a lot to think 11:02 about. Let me know your thoughts down 11:03 below. I really want to hear what you 11:05 think. If you found this valuable, 11:08 please give it a thumbs up, subscribe if 11:10 you haven't already, and share it with 11:11 anyone who needs to be part of this 11:13 conversation. Stay safe, stay informed, 11:15 and I'll see you in the next All
