Know better. Do better.

As you read this email with a cup of Joe in hand, I hate to tell you that climate change could be coming for that coffee.

You see, Arabica coffee beans aren't as, well, robust as the less popular Robusta varieties in higher temperatures. That's a problem when our planet is repeatedly blasting through global heating records.

Fortunately, my video colleague Albert Han travelled around the world to Brazil and Malaysia to find a bean which could help save your favourite brew. This is the first of several exciting new documentaries for our Rerooted series on the future of food.

By some measures, half the world's coffee-growing regions will no longer be suitable for production by 2050. But could another long-forgotten bean species become coffee's best bet to survive climate change? Join Albert as he puts that question to farmers and baristas.

Down in Australia, meanwhile, one solution to the climate crisis has been implemented for some time: solar power.

In fact, a staggering one-third of households have solar photovoltaic panels installed - the highest solar capacity per person in the world. In a region with high energy costs, the sun is helping many homeowners cope with prices.

The trouble is, reports our correspondent Rina Chandran in Adelaide, these panels are much harder to come by for renters. Social housing and rentals make up more than 30% of properties, which means they are crucial to meeting renewable energy targets. Yet only 4% of rental homes have solar power.

It's a problem of mismatched incentives, explains Dylan McConnell, a renewable energy researcher at the University of New South Wales: renters are reluctant to buy solar systems on properties they have limited rights over, while landlords won't invest when renters will get the benefits.

Efforts are underway to solve this problem, from new incentives like grants to new technologies which can increase access. One called SolShare, for example, allows apartments to share solar energy from a single rooftop system. And what happens in Australia could hold lessons for the world.

In Europe, however, another effort to tackle climate change has received a cooler reception.

Low Emission Zones, or LEZs, have been introduced to restrict polluting cars in city centres in a bid to boost air quality - such as London's Ultra Low Emission Zone (ULEZ). More than 300 are already in place and more than 500 are planned by 2025, according to Brussels-based environmental NGO Transport and Environment.

Our Europe correspondent Joanna Gill explains how this has led to widespread protests, vandalism and even conspiracy theories.

Backers say these zones can reduce serious illnesses such as asthma and heart disease. But some say the costs like daily tariffs have been difficult to shoulder for low-income communities. And conspiracy theorists have linked them, along with urban planning measures like '15-minute-cities', to a global conspiracy to take away people's freedoms through mass surveillance and fines.

And finally, after 14 years leading our award-winning climate change coverage, Laurie Goering left the newsroom this week. We wish her all the best, and will aim to build on her pioneering work as the risks of climate change - and potential solutions - multiply around the world.

See you next week,
