From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

The waste heat generated by large cities can affect temperatures in areas hundreds of miles away by changing wind patterns in the upper atmosphere, a study has found.

Scientists have estimated that the heat released into the atmosphere from buildings, cars and factories could play a significant role in the warming – and the cooling – of locations in other countries.

Using computer models of how heat is transported around the globe, the study published in the journal Nature Climate Change says that waste heat from 86 urban centres in the northern hemisphere could in theory raise temperatures of parts of North America and northern Asia by as much as 1C.

The same models suggest that other parts of the northern hemisphere, notably Europe, could actually become cooler at certain times of the year by up to 1C as a result of the heat affecting the direction of high-altitude winds such as the jet stream.
