During a hurricane, powerful winds churn and fan the ocean, leaving behind a swath of cold water that can last for weeks and weaken subsequent storms. But in parts of the ocean, these cold wakes aren’t lasting as long as they once did. “This shortening of cold wake recovery time can give a second boost to hurricane intensity” along with background warming due to climate change, says Shuai Wang at the University of Delaware.

The carbon dioxide removal industry is struggling to grow at the pace needed to have a significant role in meeting climate targetsThe nascent carbon dioxide removal industry expects to hit a milestone this year: 1 million tonnes of planet-warming CO2 removed from the atmosphere. That certainly is progress, but things aren’t moving anywhere near quickly enough to remove the billions of tonnes of carbon researchers say we need to capture annually in coming decades.

Weather forecasts based on AI are faster and sometimes more accurate than traditional ones, but they may miss rare and unprecedented weather events – which are becoming more common as the climate changesWeather forecasts can miss rare events like the extreme rainfall caused by 2017’s Hurricane HarveyTraining AI models on historical weather patterns can turn them into accurate forecasters – but they may not be able to predict extreme events that don’t occur in their training data.

Injecting carbon dioxide into rocks deep underground can turn the planet-warming gas into mineral form, permanently keeping it out of the atmosphere. Now, researchers say it may be possible to use the same process to simultaneously extract key metals used in clean electricity technology.

Fumes of ammonia rising from Antarctica’s crowded colonies of penguins play a role in boosting the formation of clouds, which have a cooling effect by reflecting sunlight away from the surface. “This demonstrates a deep connection between the ecosystem and atmospheric processes,” says Matthew Boyer at the University of Helsinki in Finland. The link comes down to the way ammonia affects the number of particles in the atmosphere.

Over the past two decades, swathes of Eurasia have seen a spike in extreme heatwaves followed by droughts. Thanks to tree rings we now this spike is way above anything seen in at least the past 300 years. 🧪 https://t.co/aYk3IcNqHa
Microplastics are pervasive even in the deepest parts of the ocean. Researchers are concerned this could slow down the ocean's ability to sequester carbon via sinking plankton. 🧪🌊 https://t.co/zeEatu4AfG
The Trump administration has dismissed all of the researchers working on the next US National Climate Assessment, a move likely to delay – if not prevent – the completion of the US government's main climate report. https://t.co/8X7Acn17F7
