Meteorologists found 52.9C reading to be false, though new record does appear to have been set

A record temperature registered this week for the Indian capital of 52.9C (127.22F) was too high by 3C, the Indian government has said.

The Indian Meteorological Department (IMD) had investigated Wednesday’s reading by the weather station at Mungeshpur, a densely packed corner of New Delhi, “and found a 3C sensor error”, the earth sciences minister, Kiren Rijiju, said.

Research that looked at 53 million births says Black and Hispanic mothers and those in lower socioeconomic groups most at risk

Heatwaves increase rates of preterm births, which can lead to poorer health outcomes for babies and impact their long-term health, a new study found.

Black and Hispanic mothers, as well as those in lower socioeconomic groups, are particularly at risk of delivering early following heat waves.

Recommendations include heat forecasts and outdoor-worker safeguards to prevent thousands of deaths and injuries

Millions of Americans face the threat of dangerous heatwaves in the coming weeks with another summer of record-breaking temperatures forecast to hit the US.

Most of New Mexico and Utah – alongside parts of Arizona, Texas and Colorado – have the highest chance (60% to 70%) of seeing hotter-than-average summer temperatures, according to the National Oceanic and Atmospheric Administration (Noaa). In addition, the entire north-east – from Maine down to Pennsylvania and New Jersey – as well as a large stretch from Louisiana to Arizona, Washington and Idaho, have a 40% to 50% chance of experiencing above-average temperatures from June through August.

High temperatures in Mexico have been linked to dozens and perhaps hundreds of deaths of howler monkeys

It’s so hot in Mexico that howler monkeys are falling dead from the trees.

At least 83 of the midsize primates, who are known for their roaring vocal calls, were found dead in the Gulf coast state of Tabasco. Others were rescued by residents, including five that were rushed to a local veterinarian who battled to save them.

Hundreds of climate experts expect global temperatures to rise to at least 2.5C (4.5F) above preindustrial levels by 2100. Damian Carrington reports

When the Guardian’s environment editor, Damian Carrington, decided to survey the world’s top climate scientists, he had no idea how many of them would want to participate.

“I was astonished by the flood of responses that came back,” he tells Hannah Moore.
