Drought in California has subsided, but the state is not yet out of the woods

Published

An extremely wet winter has saved much of California from drought and more rain is ahead. This season’s heavy rains and snowfall have “destroyed an exceptional and extreme drought in California” for the first time since 2020, according to the agency. spring forecast published today by the National Oceanic and Atmospheric Administration (NOAA).

The agency predicts further improvements throughout the spring, with more regions potentially seeing their dry conditions come to an end. Despite this, California’s recovery will be uneven, and it will take years to replenish some important water sources. On recent storms have already shownthe state will continue to face new flood hazards.

“Climate change leads to both wet and dry extremes”

“Climate change is driving both wet and dry extremes, as evidenced by NOAA observations and data underlying this seasonal forecast,” NOAA administrator Rick Spinrad said in a statement.

Maps from USA Drought Monitor illustrate the Golden State’s dramatic transition from dry to wet in just a few months. In late December, closer to the start of the winter season, 100% of the state was at least “abnormally dry.”

More than a third of California has been colored bright red to show “extreme drought” conditions on the December 27 map on the left side of the slider below. In this week’s updated drought map, there is no red to the right of the slider. Just over half of the state is now “abnormally dry.”

Record snowfall was the hallmark of the season, which also helps alleviate the drought. The state relies on snowmelt to fill rivers and reservoirs during dry seasons. According to a recent study, the amount of water infiltrating snowpack across the state was 190 percent of the average in early March. grade Department of Water Resources (DWR).

While California needs water, the way it has hit the state this season has been devastating. Communities have been repeatedly hit by rain and snow due to severe storms arriving through river of water vapor high in the atmosphere. Heavy from snow, roofs hit the houses and grocery stores in mountain towns. The last storm left over 300 000 customers without electricity this week. It was the 11th atmospheric river storm to hit the state this season, and another. can get to california by Sunday.

Increased rainfall combined with melting snow puts the state at risk of more flooding this spring, NOAA said in a forecast. It’s too early to tell what an incredibly wet winter will mean for California’s wildfires this year, state climatologist Michael Anderson said at DWR. briefing yesterday. It depends on a variety of factors, including how quickly the snow cover melts, how quickly the landscape dries out, and the timing of spring plant growth and subsequent drying.

California is experiencing “three years of extraordinary drought, and that’s just in our rearview mirror,” Anderson said. In the future, water scarcity will continue to be a problem. States groundwater basinsconsisting of underground aquifers, it will take more than one rainy season to replenish them.

Moreover, Southern California receives a lot of its water from the Colorado River Basin, which has suffered from drought for more than 20 years and is still at the center of heated negotiations over how states would share his dwindling supply.

“We have seen some pretty fantastic weather and we have seen conditions improve in many places. We still have some lingering implications that challenge California,” Anderson said at a briefing yesterday.

Jiang Yanyong, who exposed the extent of the SARS epidemic in 2003, has died at the age of 91.

Published

Jiang Yanyong, a military surgeon who rose to fame in China for exposing Beijing’s 2003 SARS suppression, was later detained and silenced after using his fame to seek justice for the government. Crackdown on Tiananmen Square, died March 11 in Beijing. hey what 91

His death was informed in the Hong Kong South China Morning Post and by Chinese human rights activist Hu Jia, who told Western news agencies that Dr. Jiang died of pneumonia in a military hospital.

In mainland China, news about Dr. Jiang’s death or other references to him were censored, highlighting that he remained a perceived political threat two decades after he came to public attention.

“I’m not a hero,” says the doctor. In 2013, state-run Beijing News quoted Jiang as describing his SARS revelations. “All I did was say a few honest things.”

Long out of the public eye and silenced by the Chinese authorities, Dr. Jiang’s defiance has taken on new historical significance during the coronavirus pandemic. parallels were brought in with Beijing’s early coverage of the number of cases of covid and SARS, or severe acute respiratory syndrome. In 2003, SARS was blamed for over 800 deaths.

And in late 2019 — weeks before the coronavirus was identified as a global threat — Wuhan optometrist Li Wenliang drew attention to an emerging public health crisis resembling SARS. On Chinese social media, he was hailed as the doctor’s heir. Whistleblower Jiang’s Legacy. Lee died of covid in February 2020 and was announced among the official “martyrs” to fight covid.

Dr. Jiang’s challenge against the state over the SARS report drew mixed reactions from leaders. State media called him an “honest doctor” and a “SARS hero”. Many Chinese considered him a rare risk-taker among the pampered elite, a man willing to stake his state-granted privileges for the sake of his conscience.

At the same time, officials tried to dampen his rising prominence, fearing that he might use it to cast doubt on other versions of the government. “We have 6 million doctors and healthcare workers,” said Gao Qiang, number 1 in the US. In 2003, a health ministry official told The Washington Post that “Jiang Yanyong is one of them.”

The virus first appeared in late 2002 in the southern city of Guangzhou. But the Chinese authorities concealed its distribution until early February 2003. Finally, a text message from health officials said, “Influenza is rampant in Guangzhou.”

In the middle of March World Health Organization issued the first warning about the virus, but the Chinese media ignored it. Then, on April 3, 2003, Health Minister Zhang Wenkang told a press conference that China was “safe” and that “SARS was under effective control” with only 12 cases and three deaths reported in Beijing.

Dr. Jiang was outraged. Even though he was half retired, he knew military hospitals were facing a surge in SARS patients – more than 100 cases in Beijing alone. He sent an email to China Central Television and the Hong Kong television station Phoenix accusing Zhang, who was also a doctor with a military background, of covering up the true SARS numbers.

“All the doctors and nurses who saw yesterday’s news were furious,” he wrote, accusing Zhang of “giving up on his most basic standard of integrity as a doctor.”

None of the stations followed the doctor. Jiang’s message. It was leaked to Time magazine, which published a story April 8, 2003, titled “The SARS attack in Beijing”.

International pressure on China has intensified, and the WHO wondered if Beijing was hiding the extent of the epidemic. The Chinese leadership immediately fired Zhang and Beijing Mayor Meng Xuenong, while public health officials took aggressive measures to contain the spread.

“I felt I had to talk about what was going on,” the doctor said. Jiang said“not only to save China, but also to save the world.”

But dr. Jiang’s rise was soon followed by a sharp fall. He crossed a red line in China that few dare, publicly calling for retribution for the 1989 Tiananmen massacre. There is no official death toll among the pro-democracy protesters who have occupied the square, with estimates ranging from a few hundred to over 10,000.

Tiananmen remains an untouchable topic in China’s political and public life. Dr. Jiang’s position as a member of the Communist Party and a high-ranking military officer gave his comments an additional level of unease for leaders.

“Our party must correct the mistakes it has made,” said Dr. K. Jiang, who was on duty at No. 1.301 Military Hospital in Beijing, in a letter to party officials the night the tanks rolled into the square. “Everyone whose family members have been unjustly killed should make the same request.”

Dr. Jiang and his wife Hua Zhongwei were placed under house arrest. Jiang was taken into custody for more than six weeks during “political indoctrination sessions.” He was banned from communicating with foreign media and banned from leaving the country. He has virtually disappeared from public view, save for a few state-controlled remarks.

After his detention in 2004, Chinese officials made a brief statement to The Post, stating that the military “assisted and trained him”.

Jiang Yanyong was born on October 1 in Hangzhou. January 4, 1931 and grew up in nearby Shanghai in a family consisting of banking. He said he decided to pursue a career in medicine after watching his aunt die of tuberculosis.

He studied at Yanqing University in Beijing after Mao Zedong’s communist forces came to power in 1949. He received his medical education in Beijing Union Medical College and later enlisted in the medical corps of the Chinese army.

Dr. Jiang was sent to Beijing 301 Hospital in 1957. His family background, however, placed him under the influence of Mao’s Cultural Revolution launched in 1966 against foreign influence and others who were seen as potential enemies of the state.

Dr. Jiang was branded a counter-revolutionary because of his father’s banking connections and his pedigree. His cousin Chiang Yan-shih was a high-ranking official in Mao’s rival, the Kuomintang, whose leaders fled to Taiwan after being defeated in the civil war by the Communists.

Dr. Jiang was imprisoned and then exiled to the western provinces of China. He was allowed to return to No. 301 hospital in the early 1970s after he was declared “politically exonerated”. He stepped down as chief surgeon shortly before the SARS outbreak, but retained ties to the hospital to treat patients and educate doctors.

In 2007, hello what is forbidden leave China to receive a human rights award from the New York Academy of Sciences.

In addition to his wife, the survivors include a daughter and a son.

At the end of the life of Dr. Jiang had one last quarrel with the authorities. In 2019, on the 30th anniversary of the Tiananmen Square massacre, he sent a letter to Chinese leader Xi Jinping demanding he take responsibility for the events of June 1989. Jiang was placed under house arrest again.

We finally have evidence of active volcanoes on Venus

Venus is almost the same size, mass and density as the Earth. Thus, it must generate heat within itself (due to the decay of radioactive elements) at almost the same rate as the Earth. On Earth, one of the main ways this heat escapes is through volcanic eruptions. On average, at least 50 volcanoes erupt annually.

But despite decades of searching, we haven’t seen clear signs of volcanic eruptions on Venus – until now. New research geophysics Robert Herrick University of Alaska Fairbanks, which he reported this week at the Lunar and Planetary Science Conference in Houston and published in the journal Sciencefinally caught one of the planet’s volcanoes in action.

It is not easy to study the surface of Venus because it has a dense atmosphere, including a continuous cloud layer at an altitude of 45-65 km, which is opaque to most wavelengths of radiation, including visible light. The only way to get a detailed view of the ground above the clouds is to use a radar pointing down from an orbiting spacecraft.

A technique known as aperture synthesis is used to create an image of a surface. This combines the varying strengths of ground-reflected radar echoes, including the time delay between transmission and reception, as well as small frequency shifts corresponding to whether the spacecraft is approaching or moving away from the source of a particular echo. The resulting image looks like a black and white photograph, except that the brighter areas generally correspond to rougher surfaces, and the darker areas generally correspond to smoother surfaces.

NASA’s Magellan probe orbited Venus from August 1990 to October 1994 and used such radar techniques to map the planet’s surface with a spatial resolution of about a hundred meters at best. It showed that more than 80 percent of the surface is covered in lava flows, but how the youngest of them erupted recently, and whether any eruptions are still ongoing today, remained a mystery for the next three decades.
