Earth's average temperature remained at a record high Wednesday, after two days in which the planet reached unofficial records. It's the latest marker in a series of climate-change-driven extremes.

The average global temperature was 17.18 Celsius (62.9 degrees Fahrenheit), according to the University of Maine's Climate Reanalyzer, a tool that uses satellite data and computer simulations to measure the world's condition. That matched a record set Tuesday of 17.18 Celsius (62.9 Fahrenheit), and came after a previous record of 17.01 Celsius (62.6 degrees Fahrenheit) was set Monday.

The International Seabed Authority — the United Nations body that regulates the world's ocean floor — is preparing to resume negotiations that could open the international seabed for mining, including for materials critical for the green energy transition.

Years long negotiations are reaching a critical point where the authority will soon need to begin accepting mining permit applications, adding to worries over the potential impacts on sparsely researched marine ecosystems and habitats of the deep sea.

Kenyan President William Ruto has lifted a six-year ban on logging over the concerns of environmentalists.

The president said Sunday it was "foolish" to have mature trees rotting in forests while local industries lacked timber.

Luis Ramirez leapt onto the roof of his bright blue water truck to fill the plastic tank that by day's end would empty into an assortment of buckets, barrels and cisterns in 100 homes.

It was barely 11 a.m. and Ramirez had many more stops to make on the hilly, grey fringes of Tijuana, a sprawling, industrial border city in northwestern Mexico where trucks or "pipas" like Ramirez's provide the only drinking water for many people.

At least 15 people have been killed by floods in southwestern China as seasonal torrents hit mountain areas, authorities said Wednesday.

Another four people were reported missing by mid-morning in Chongqing, a vast mountainous region of 31 million, almost all of which has now been designated as having flood risk, according to the local government website.

The United Nations on Tuesday warned the world to prepare for the effects of El Nino, saying the weather phenomenon which triggers higher global temperatures is set to persist throughout 2023.

El Nino is a naturally occurring climate pattern typically associated with increased heat worldwide, as well as drought in some parts of the world and heavy rains elsewhere.

The head of the United Nations called Monday for maritime nations to agree on a course for the shipping industry to reduce its climate-harming emissions to net zero by the middle of the century at the latest.

The appeal by U.N. Secretary-General Antonio Guterres came at the start of a meeting of the International Maritime Organization in London that's seen as key for helping achieve the international goal of limiting global warming to 1.5 degrees Celsius (2.7 Fahrenheit).

Heavy flooding has displaced thousands of people around China as the capital had a relative respite from sweltering heat.

Beijing reported 9.8 straight days when the temperature exceeded 35 C (95 F), the National Climate Center said Monday.

The baby sea turtle flapped its flippers as it was lowered into the ocean, only to be pushed back ashore by the strong tide. It tried again, and this time it made it, swimming fast and deep into Persian Gulf waters lapping at a string of beachfront tourist resorts.

Scientists hope the turtle will thrive back in its natural habitat, joining about 500 sea turtles that have been rescued, rehabilitated and released since Abu Dhabi's Environment Agency launched a program three years ago to aid turtles distressed by climate change and other issues.

The German government said Monday it is launching a campaign against deaths from heat waves that are becoming more frequent and intense due to climate change.

Health Minister Karl Lauterbach said Germany is learning lessons from France, which put in place numerous measures following a devastating heat wave in 2003 that caused about 15,000 deaths in the country.
