Dry conditions draw emu mobs from outback to city streets
By Oliver Brown

A wildlife rescuer is urging people to take caution as drought conditions force emus to migrate from their usual outback habitat into Broken Hill in search of refuge and water.

As the weather dries up in SA, so does cash for small businesses
By Viki Ntafillis and Kate Higgins

Small businesses in parts of regional South Australia are feeling the pinch, as farmers and their families tighten their belts amid record-low rainfall.

Nearly 200,000 litres of water stolen from Adelaide Hills tanks, residents say
By Malcolm Sutton

With many rainwater tanks across the Adelaide Hills running low or on empty due to an ongoing dry spell, two residents say thieves have used water trucks to steal nearly 200,000 litres overnight.

How a Changing Climate Is Reshaping the Spread of Infectious Diseases

"...Then you have this convergence of crises—the #ClimateCrisis overlapping with the #PollutionCrisis. So you get this intersection between air pollution and respiratory #diseases, and then infectious diseases more broadly, all layered on top of a changing #climate.

When it comes to waterborne and foodborne diseases, the link to #ClimateChange is even more direct. As temperatures rise, you create more favorable conditions for #bacteria and other #pathogens to multiply. They thrive in warm environments—soil, water, contaminated areas—so warming can increase their abundance.

#ExtremeWeather events are also a big factor here. Aedes #mosquitoes need water to complete their life cycle—from egg to larva to pupa, it all happens in #water. When #floods occur, all the discarded #plastic and #trash lying around fill with water and becomes the ideal breeding ground for mosquitoes.

What’s interesting is that these diseases aren’t just associated with floods—they’re also linked to #droughts. That might seem counterintuitive at first, but in many parts of the world, people don’t have safe, reliable access to clean water, especially during drought conditions. So they store water in containers that aren’t properly sealed or protected, which too can become the perfect breeding sites for mosquitoes.

Infections—particularly vector-borne diseases—are increasingly reemerging and emerging in new areas around the world for a lot of different reasons. Climate change is definitely part of that, with rising temperatures and more extreme weather events like floods and droughts. But the way we live our lives and interact with the environment also plays a huge role. I mean, first and foremost, most of us now live in urban areas rather than rural ones..."

Mosquitoes, for example, rely heavily on ambient temperature. They’re ectotherms, meaning they depend on room temperature to function. Every vector species has multiple traits that are influenced by temperature. If you map all those temperature-dependent traits, you can build a curve that shows the optimal temperature range for that vector. Depending on where you fall on that curve, if you’re already past the peak and temperatures keep rising, there’s actually the potential for a decrease in transmission risk. But these systems are highly nuanced. It’s not just about temperature—it’s also about human behavior and how we alter natural habitats. And vectors can evolve, too. So it’s almost like we’re in a race with other organisms to adapt more quickly.

Aussie farmers' grain gamble as rain fails to arrive before Anzac Day
By Emma Field and Selina Green

Anzac Day marks the traditional start for planting winter crops, but this year farmers are hoping for rain as they begin planting their crops in the dry.

CBC: This atmospheric trend is devastating crops (and no one’s talking about it)

Scientists have coined a new term: thirstwaves. The phenomenon occurs during extended periods of unusually high evaporation — caused not from a lack of rain, but because the air is extra thirsty. Johanna Wagstaffe breaks down how thirstwaves could seriously affect farming and water supplies.

Economic vulnerabilities to climate change
Average person will be 40% poorer if world warms by 4C, new research shows

“In a hotter future, we can expect cascading supply chain disruptions triggered by extreme weather events worldwide. New research had looked at the likely impact of global heating of 4C – seen by many climate experts as catastrophic for the planet – finding it would make the average person 40% poorer."

Can renewable energy survive climate change?

As #droughts reduce #hydropower and #clouds dim #solar output around the world, experts say #meteorology and #ClimateScience must be at the heart of the #energy transition.

Yet, even as the push for renewables gains momentum – driven by cheaper technology and an urgent need to slash carbon emissions – experts are waving cautionary flags: Because renewable energy sources depend on weather conditions, climate change is increasingly dictating, and jeopardizing, renewable energy production.

"Climate change poses a particular risk to pine trees growing in dry areas, a new University of Eastern Finland study conducted in an urban recreational forest in Helsinki shows.
Tree mortality has increased in the 21st century. This phenomenon is primarily driven by drought, heat waves, pests and forest fires, all of which have become more common with climate change".

"Determining the degree to which shifting drought conditions around the world are attributable to natural hydroclimatic variability and how much they are caused by climate change is a complicated task. Scientists often use complex computer models to simulate past climate variability and to identify unprecedented drought conditions".
