With Russia’s invasion of Ukraine and the specter of nuclear weapon use, Earth crept its closest to Armageddon, a science-oriented advocacy group said, moving its famous “Doomsday Clock” up to just 90 seconds before midnight.

“We are really closer to that doomsday,” former Mongolian president Elbegdorj Tsakhia said Tuesday at the Bulletin of Atomic Scientists annual announcement rating how close humanity is from doing itself in. He and former Ireland President Mary Robinson joined scientists to underscore what they consider a gathering of several existential threats, with Russian leader Vladimir Putin's actions and words chief among them.

“People and scientists are warning us and we have to wake up now,” he said.

The advocacy group started in 1947 to use a clock to symbolize the potential and likelihood of people doing something to end humanity. It moved the clock 10 seconds closer than last year, making it the closest it has ever been to striking 12. It's been as much as 17 minutes from midnight after the end of the Cold War but in the past few years, the group has changed from counting down the minutes to midnight to counting down the seconds.

Doomsday has not happened yet.

“We are sending a message that the situation is becoming more urgent,” Bulletin President Rachel Bronson said at the online announcement. “Crises are more likely to happen and have broader consequences and longer standing effects.”

And to emphasize the effect that Russia’s invasion of Ukraine had on moving closer to theoretical doomsday, the group said it was also announcing the clock movement in the Russian and Ukrainian languages for the first time.

“Putin has repeatedly raised the specter of nuclear use,” said Steve Fetter, dean of the graduate school and a public policy professor at the University of Maryland.

“Putin has given no indication that he's willing to accept defeat,” Fetter said. “He might make desperate moves if no other options are available that he regards as acceptable.”

Scientists and activists at the Bulletin announcement also mentioned nuclear weapon proliferation in China, Iran increasing its uranium enrichment, missile tests in North Korea, future pandemics from animal diseases, pathogens from lab mistakes, “disruptive technologies” and worsening climate change as other existential threats to humanity.



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
