“I haven’t experienced heat like this before,” Mr. Alam said. “Every year gets hotter, but this year is extreme.”

2023 was unusually hot, both on land and in the ocean. (The oceans absorb over 90 percent of the excess heat caused by global warming.) It was the hottest year in over 170 years of record keeping, even exceeding scientists’ predictions.

2015 and 2016 brought significant bleaching events, which resulted in 80% mortality of corals. “They cooked the reef,” he said. More than half of the world’s coral reef cover has now been lost since 1950. If global heating reaches 2C, more than 99% of coral reefs are expected to start dying.

Supplies at the Chingaza reservoir, which supplies 70% of the capital’s water, are at 16% – the lowest on record. Bogotá’s public water utility estimates there could be about 54 days’ worth of water left. To prevent a disaster, local officials have divided Bogotá into nine zones, each of which will be cut off from the water grid for 24 hours on rotation.

About 11,500 years ago during the Younger Dryas era, temperatures in Greenland leaped 10 degrees Celsius in a decade, with the rest of the world seeing a matching jump to a new state in a matter of decades, not centuries.

This is the 10th consecutive monthly record in a warming phase that has shattered all previous records. Over the past 12 months, average global temperatures have been 1.58C above pre-industrial levels.

On March 18, 2022, scientists at the Concordia research station on the east Antarctic plateau recorded the largest jump in temperature ever measured at a meteorological facility anywhere on Earth. According to their instruments, the temperature outside that day was 38.5º C (69.3º F) above its seasonal average — a world record.

“The level of heat the globe has experienced over the last 12 months, both on the land and in the ocean has surprised science,” said Prof Benjamin Horton, the director of the Earth Observatory of Singapore. “We always knew we were going to be headed in this direction with our increasing greenhouse gases, but the fact that we’re shattering all these records in 2023, and 2024, is perhaps slightly ahead of time.”

Brightening clouds is one of several ideas to push solar energy back into space — sometimes called solar radiation modification, solar geoengineering, or climate intervention. Compared with other options, such as injecting aerosols into the stratosphere, marine cloud brightening would be localized and use relatively benign sea salt aerosols as opposed to other chemicals.
