From a university campus to a seaside town, Pope Francis challenged young people on Thursday to make the world a more just and inclusive place, as he focused the second day of his Portugal trip on inspiring students to use their privilege to combat global warming and economic inequalities.

Francis received a warm welcome first at the Catholic University in Lisbon, one of Portugal's top institutions of higher learning. He then had a more intimate, informal encounter with young people in the former fishing village of Cascais, where he was serenaded with a mournful performance of the traditional Portuguese fado, meaning fate or destiny.

The typhoon that damaged homes and knocked out power on Okinawa and other southern Japanese islands this week was slowly moving west Thursday but is forecast to make a U-turn and dump even more rain on the archipelago.

Typhoon Khanun, now in the waters between China and Japan's southwestern islands, is expected to slow to nearly stationary movement before a weakening high pressure system nearby allows it to turn east Friday, the Japan Meteorological Agency said.

Northeastern Spain's Catalonia region has declared a drought emergency in 24 municipalities following a severe lack of rain in recent years.

Restrictions put in place as part of the emergency will principally affect agricultural and industrial water usage but not drinking water, Catalonia Water Agency Director Samuel Reyes said at a news conference.

Visits to the Acropolis of Athens, Greece's most popular archaeological site, will be capped starting next month at a maximum 20,000 daily and subject to varying hourly entry limits, the Greek government said Wednesday.

Culture Minister Lina Mendoni said the controls are needed to prevent bottlenecks and overcrowding at the UNESCO World Heritage site. As many as 23,000 people a day have been squeezing into the monument complex, mostly large groups visiting before noon.

After recording the warmest monthly average temperature for any U.S. city ever in July, Phoenix climbed back up to dangerously high temperatures. That could mean trouble not just for people but for some plants, too.

Residents across the sprawling metro are finding the extended extreme heat has led to fried flora, and have shared photos and video of their damaged cacti with the Desert Botanical Garden. Nurseries and landscapers are inundated with requests for help with saguaros or fruit trees that are losing leaves.

China's capital has recorded its heaviest rainfall in at least 140 years over the past few days after being deluged with heavy rains from the remnants of Typhoon Doksuri.

The city recorded 744.8 millimeters (29.3 inches) of rain between Saturday and Wednesday morning, the Beijing Meteorological Bureau said Wednesday.

During Europe's heat wave last month, Floriana Peroni's vintage clothing store had to close for a week. A truck of rented generators blocked her door as they fed power to the central Roman neighborhood hit by a blackout as temperatures surged. The main culprit: air conditioning.

The period — in which temperatures hit 40 degrees Celsius (104 degrees Fahrenheit) — coincided with peak electricity use that came close to Italy's all-time high, hitting a peak load of more than 59 gigawatts on July 19. That neared a July 2015 record.

A powerful typhoon slammed Okinawa and other islands in southwestern Japan Wednesday with high winds injuring more than 30 people as it moved west making its way toward mainland China.

The Japan Meteorological Agency said the typhoon is heading to the East China Sea, but may change course and head back to Japan later this week.

Human-caused global warming made July hotter for four out of five people on Earth, with more than 2 billion people feeling climate change-boosted warmth daily, according to a flash study.

More than 6.5 billion people, or 81% of the world's population, sweated through at least one day where climate change had a significant effect on the average daily temperature, according to a new report issued Wednesday by Climate Central, a science nonprofit that has figured a way to calculate how much climate change has affected daily weather.

There are now more golden lion tamarins bounding between branches in the Brazilian rainforest than at any time since efforts to save the species started in the 1970s, a new survey reveals.

Once on the brink of extinction, with only about 200 animals in the wild, the population has rebounded to around 4,800, according to a study released Tuesday by the Brazilian science and conservation nonprofit Golden Lion Tamarin Association.
