A global research effort worth tens of billions of dollars is needed to ensure the world is better prepared for the next pandemic, which could be far worse than Covid, Bill Gates has said.

Bill Gates ‘left Microsoft board amid inquiry into relationship with employee’

Board members reportedly felt his presence was inappropriate during the investigation into a romantic relationship last year

Bill Gates: ‘Carbon neutrality in a decade is a fairytale. Why peddle fantasies?’

After putting $100m into Covid research, the billionaire is taking on the climate crisis. And first he has some bones to pick with his fellow campaigners...

Bill Gates appears via video conference – Microsoft Teams, not Zoom, obviously – from his office in Seattle, a large space with floor-to-ceiling windows overlooking Lake Washington. It’s a gloomy day outside and Gates is, somewhat eccentrically, positioned a long way from the camera, behind a large, kidney-shaped desk; his communications manager sits off to one side. If one had to stage, for the purposes of symbolism, a tableau of a man for whom a distance of 3,000 miles between callers still constitutes too intimate a setting, it might be this. “As a way to start,” says Gates’ aide, “would it be helpful for Bill to make a couple of comments about why he wrote his new book?” It is helpful, and I’m not ungrateful, but this is not how interviews typically commence.

There is an urge towards deference, when speaking to Gates, which attends few other people of commensurate fame. Celebrity is one thing, but wealth – true, former-richest-man-in-the-world wealth – is something else entirely; one has a sense of being granted an audience with the Great Man, a fact made more surreal by his famously muted persona. The 65-year-old has the lofty, mildly longsuffering air of a man accustomed to being the smartest guy in the room, leavened by wry amusement and interrupted, on the evidence of past interviews, by the occasional peevish outburst – most memorably in 2014, when Jeremy Paxman questioned him about Microsoft’s alleged tax avoidance. (“I think that’s about as incorrect a characterisation of anything I’ve ever heard,” he said, practically squirming in his seat with annoyance.)

How to Avoid a Climate Disaster by Bill Gates; The New Climate War by Michael E Mann – review

Two eminent voices on the climate crisis present clear strategies for tackling emissions, deniers and doomsayers

President Joe Biden has promised a new era of American leadership on global climate action, after four years of unscientific denial and misinformation under Donald Trump. Two important new books by prominent American authors, both written before the result of the presidential election was known, should help to capitalise on the new spirit of cautious optimism by laying out bold but well-argued plans for accelerating action against climate change.

How to Avoid a Climate Disaster: The Solutions We Have and the Breakthroughs We Need by Bill Gates presents a compelling explanation of how the world can stop global warming by reducing greenhouse gas emissions effectively to zero. Gates and his wife, Melinda, are well known for their foundation’s tremendous work on improving health and tackling disease around the world, particularly in poor countries. It is this concern for the most vulnerable people on the planet that has meant Gates has occasionally appeared equivocal about climate and energy policies that he thought could undermine the fight against poverty and illness. However, this book lays out forcefully his understanding that the impact of climate change poses a far bigger threat to lives and livelihoods in developing countries – it is thwarting efforts to raise living standards because poor people, in every country, are the most at risk from droughts, floods and heatwaves.

Is big tech now just too big to stomach?

The Covid crisis has turbo-charged profits and share prices. But are the big six now too powerful for regulators to ignore?
