The UN just handed out an urgent climate to-do list. Here’s what it says.

Time is running short to limit global warming to 1.5°C (2.7 °F) above preindustrial levels, but there are feasible and effective solutions on the table, according to a new UN climate report.

Despite decades of warnings from scientists, global greenhouse-gas emissions are still climbing, hitting a record high in 2022. If humanity wants to limit the worst effects of climate change, annual greenhouse-gas emissions will need to be cut by nearly half between now and 2030, according to the report.

That will be complicated and expensive. But it is nonetheless doable, and the UN listed a number of specific ways we can achieve it. Read the full story.

How people are using GPT-4

Last week was intense for AI news, with a flood of major product releases from a number of leading companies. But one announcement outshined them all: OpenAI’s new multimodal large language model, GPT-4. William Douglas Heaven, our senior AI editor, got an exclusive preview. Read about his initial impressions.  

Unlike OpenAI’s viral hit ChatGPT, which is freely accessible to the general public, GPT-4 is currently accessible only to developers. It’s still early days for the tech, and it’ll take a while for it to feed through into new products and services. Still, people are already testing its capabilities out in the open. Read about some of the most fun and interesting ways they’re doing that, from hustling up money to writing code to reducing doctors’ workloads.

Language models might be able to self-correct biases—if you ask them

The news: Large language models are infamous for spewing toxic biases. But if the models are large enough, and humans have helped train them, then they may be able to self-correct for some of these biases, a new paper from AI lab Anthropic has found. Remarkably, all we have to do is ask.

How they did it: The team of researchers wanted to know if simply asking these models to produce output that was unbiased—without even having to define what they meant by bias—would be enough to alter what they produced. They found that just prompting a model to make sure its answers didn’t rely on stereotyping had a dramatically positive effect on its output. 

The significance: The work raises the obvious question whether this “self-correction” could and should be baked into language models from the start. Read the full story.

The big story

This scientist is trying to create an accessible, unhackable voting machine

November 2022

For the past 19 years, computer science professor Juan Gilbert has immersed himself in perhaps the most contentious debate over election administration in the United States—what role, if any, touch-screen ballot-marking devices should play in the voting process.

While advocates claim that electronic voting systems can be relatively secure, improve accessibility, and simplify voting and vote tallying, critics have argued that they are insecure and should be used as infrequently as possible. 

As for Gilbert? He claims he’s finally invented “the most secure voting technology ever created.” And he’s invited several of the most respected and vocal critics of voting technology to prove his point. Read the full story.
