More than 5,000 people isolated by flooding in northwest North Korea were rescued in airlifts and other evacuation work supervised by leader Kim Jong Un, state media reported Monday.

Heavy rainfall on Saturday had caused a river on the North Korean-Chinese border to exceed a dangerous level and created "a grave crisis," the official Korean Central News Agency said.

Firefighters made progress and were aided by improving weather Sunday in the battle against wildfires covering massive areas and leaving a trail of damage in the western United States, but further evacuations and resources have been necessary as thousands of personnel tackle the flames.

The so-called Park Fire, the largest wildfire in California this year, was one of more than 100 blazes burning in the U.S. on Sunday, according to the National Interagency Fire Center. Some were sparked by the weather, with climate change increasing the frequency of lightning strikes as the western U.S. endures blistering heat and bone-dry conditions.

One of the most enduring images of Greece's summer travel brand is the world-famous sunset on Santorini Island, framed by sea-blue church domes on a jagged cliff high above a volcanic caldera.

This scene has inspired millions of fridge magnets, posters, and souvenirs -- and now the queue to reach the viewing spot in the clifftop village of Oia can take more than 20 minutes.

After three of Earth's hottest days ever measured, the United Nations called for a flurry of efforts to try to reduce the human toll from soaring and searing temperatures, calling it "an extreme heat epidemic."

"If there is one thing that unites our divided world, it's that we're all increasingly feeling the heat," United Nations Secretary-General Antonio Guterres said Thursday at a news conference where he highlighted that Monday was the hottest day on record, surpassing the mark set just a day earlier. "Earth is becoming hotter and more dangerous for everyone, everywhere."

The Paris Olympics were getting off to a rougher than hoped-for start Friday, with suspected acts of sabotage targeting France's flagship high-speed rail network and cloudy skies with light drizzle over the French capital ahead of its sprawling, ambitious opening ceremony.

On a day of utmost importance for France and its capital, with dozens of heads of state and government in town for the Olympic opening and a global audience of over 1 billion expected to tune in, authorities were scrambling to deal with widespread rail disruptions caused by what they described as coordinated overnight sabotage of high-speed train lines.

What was Typhoon Gaemi was heading to inland China on Friday after weakening to a severe tropical storm soon after making landfall on the east coast the previous night.

The storm felled trees, flooded streets and damaged crops in China but there were no immediate reports of casualties or major damage. Five people died in Taiwan, which Gaemi crossed at typhoon strength on Thursday before heading over open waters to China.

Heavy rain in the past week has triggered floods and landslides in Japan, disrupting transportation and forcing residents to take shelter on safer ground. Four people were missing Friday, including two police officers.

The rain had subsided in Yamagata and Akita prefectures Friday, but the area was still at risk of flooding and landslides. Prime Minister Fumio Kishida urged people to "put safety first."

Taiwan has seen flooding in low-lying areas, along with landslides and damage to homes and shops after Typhoon Gaemi made landfall on the island.

The storm swept up the western Pacific, leaving 22 people dead in the Philippines from flooding and landslides, and three in Taiwan, with more than 220 reported injured.

Global temperatures dropped a minuscule amount after two days of record highs, making Tuesday only the world's second-hottest day ever.

The European climate service Copernicus calculated that Tuesday's global average temperature was 0.01 Celsius (0.01 Fahrenheit) lower than Monday's all-time high of 17.16 degrees Celsius (62.8 degrees Fahrenheit), which was .06 degrees Celsius hotter (0.1 degrees Fahrenheit) than Sunday.

To combat ongoing destruction in the Amazon rainforest, Brazil announced a plan Tuesday to dramatically expand selective logging to an area the size of Costa Rica over the next two years.

In Brazil, vast forest lands are designated as public yet have no special protection or enforcement and are vulnerable to land grabbing and illegal deforestation. Criminals frequently take over land and clear it, hoping the government will eventually recognize them as owners, which usually happens.
