India’s Cloud Seeding Trials Criticized as ‘Costly Spectacle’



India’s attempt to tackle New Delhi’s toxic air by using cloud seeding appears to have produced disappointing results, with scientists and activists questioning whether the costly experiment was worth it.

Cloud seeding — a process in which aircraft spray particles such as silver iodide or salt into clouds to induce rainfall is intended to help wash pollutants out of the atmosphere.

Authorities in Delhi, in collaboration with the Indian Institute of Technology (IIT) Kanpur, began the trials last week using a Cessna aircraft over parts of the capital.

However, officials said the initial tests yielded minimal rainfall due to limited cloud cover.

“This will never do the job it’s an illusion,” said environmental activist Bhavreen Kandhari. “We can only control air pollution by addressing its sources, not by chasing clouds.”

Local media reported that the government has spent around $364,000 on the project so far.

Each winter, a thick blanket of smog envelops Delhi and its 30 million residents, as cold air traps emissions from vehicle exhaust, factory smoke, and crop burning in nearby states.

Despite various government efforts including vehicle restrictions, anti-smog towers, and mist-spraying trucks Delhi consistently ranks among the world’s most polluted capitals.

Following the latest cloud seeding attempt, levels of PM2.5 the fine particles linked to heart and lung disease reached 323 micrograms per cubic meter, over 20 times the World Health Organization’s safe daily limit.

A study published in The Lancet Planetary Health last year estimated that 3.8 million deaths in India between 2009 and 2019 were associated with air pollution exposure.

Questions also remain about the environmental impact of cloud seeding chemicals.

The U.S. Environmental Protection Agency (EPA) says limited research suggests silver iodide poses little risk to human health or the environment, but acknowledges that the long-term effects of widespread use remain unclear.

Research process

Environmental activists say even if cloud seeding produces rain, the benefits are short-lived.

Climate scientist Daniele Visioni at Cornell University said it was unclear how efficient it was in heavy polluted conditions.

“It can’t create rain where there is no moisture in the air, but it just ‘forces’ some of the water to condense in one location rather than another,” he told AFP.

“There is only one thing that can sensibly reduce pollution: avoiding the burning of fossil fuels.”

Virendra Sachdeva, from Delhi’s ruling Bharatiya Janata Party (BJP), said it was too early to dismiss the cloud seeding experiment as a “scientific failure”.

“It is a part of the research process, and success is not always achieved in the first attempt,” he told reporters.

However, two atmospheric scientists at IIT Delhi called the cloud seeding plan “another gimmick”.

“It is a textbook case of science misapplied and ethics ignored,” Shahzad Gani and Krishna Achutarao wrote in The Hindu newspaper.

Mohan George, from the Delhi-based Centre for Science and Environment, said artificial rain was not the answer.

“The levels of pollution will come back almost immediately as rain stops,” the scientist told AFP.

When it does work, it will increase precipitation in one area — while potentially decreasing it for another.

Costly spectacle

Cloud seeding, first developed in the 1940s, has been used in various countries to induce rain, clear fog, and reduce drought, but with mixed results.

China used it during the 2008 Beijing Olympics in an attempt to control the weather.

Gani and Achutarao said Delhi’s pollution causes — unchecked emissions and seasonal crop burning — are well known.

So too are the solutions cleaner fuel, better waste management and stricter enforcement of rules.

“Instead of reinforcing these priorities, parts of the scientific ecosystem researchers, advisors, and institutions — are lending credibility to a costly spectacle that will do little to address the sources of the crisis,” they said.

Iran says US naval blockade has minimal impact on food supply

Iran says US naval blockade has minimal impact on food supply



Iran’s agriculture minister said a US naval blockade has had little impact on the country’s ability to supply basic goods and food, citing strong domestic production and alternative import routes.

“Despite the US naval blockade, we have no problem in supplying basic goods and food because, due to the size of the country, it is possible to import from different borders,” Agriculture Minister Gholamreza Nouri said on Tuesday.

“About 85 percent of agricultural products and basic goods are produced domestically, so the country’s food security is established,” he added, according to the official IRNA news agency.

The United States imposed a naval blockade on Iran’s ports and coasts on April 13, days after a ceasefire was announced that paused its war with Iran.

Iran has strongly criticised the blockade, describing it as a violation of the ceasefire.

US missile stockpiles sharply depleted during Iran war: report

US missile stockpiles sharply depleted during Iran war: report

The United States military used up nearly half of its Patriot interceptor missile stockpile during its seven-week campaign against Iran, according to an analysis by the Center for Strategic and International Studies (CSIS).

A report by Washington-based outlet The Hill highlighted significant depletion across several key munitions, citing the CSIS analysis, and raised concerns about Washington’s preparedness for a potential conflict with China.

According to the CSIS study released on Tuesday, US forces fired almost 50% of their Patriot missiles during the operation. More than half of Terminal High Altitude Area Defence (THAAD) interceptors were also used, alongside over 45% of Precision Strike Missiles (PrSMs), during the air and missile campaign in Iran.

The analysis further found that more than 20% of Joint Air-to-Surface Standoff Missiles (JASSMs), over 30% of SM-3 interceptors and at least 10% of SM-6 missiles were expended as part of Operation Epic Fury.

CSIS warned that rebuilding stockpiles — including Tomahawk cruise missiles and JASSMs — to pre-operation levels could take between one and four years. These weapons, it noted, would be vital in any future conflict in the Western Pacific.

“Even before the Iran war, stockpiles were deemed insufficient for a peer competitor fight. That shortfall is now even more acute and building stockpiles to levels adequate for a war with China will take additional time,” the report’s authors wrote.

While the US is still likely to retain enough munitions to continue operations against Iran, the remaining inventory would fall short in a confrontation with a major adversary such as China, the report added.

Amid these concerns, the United States Central Command (Centcom), which led the Iran campaign, said its forces are actively rebuilding capacity during the ceasefire. In a social media message, CENTCOM said its “forces remain ready”.

Speaking alongside US Defence Secretary Pete Hegseth, Centcom commander Admiral Brad Cooper said: “We are rearming. We’re retooling, and we’re adjusting our tactics, techniques and procedures.”

“There is no military in the world that adjusts like we do, and that’s exactly what we’re doing right now during the ceasefire,” he added.

The findings come as President Donald Trump earlier held talks with leading defence contractors in March, after which he said production of “exquisite class” weapons would be increased fourfold.

Responding to the report, Pentagon chief spokesperson Sean Parnell defended the military’s capabilities, telling The Hill that the US remains fully equipped.

“The US military is the most powerful in the world and has everything it needs to execute missions at the time and place of the President’s choosing,” he said.

“As Secretary [Pete] Hegseth has highlighted numerous times, it took less than 10% of American naval power to control traffic in and out of the Strait of Hormuz. Since President Trump took office, we have executed multiple successful operations across combatant commands while ensuring the US military possesses a deep arsenal of capabilities to protect our people and our interests,” Parnell said in a statement. “Attempts to alarm Americans over the Department’s munitions stockpiles are both ill-informed and dishonourable.”

Meanwhile, Pentagon comptroller Jules ‘Jay’ Hurst said officials are planning to expand multi-year munitions contracts to as long as seven years, aimed at strengthening supply chains and encouraging sustained investment. The move forms part of the administration’s proposed $1.5 trillion defence budget.

“Once Operation Epic Fury ends, the naval assets sent to the Middle East will return to the Pacific. Munitions inventories will start to recover, but restoring depleted stockpiles and then achieving the desired inventory levels will take many years,” the report’s authors, Mark F. Cancian and Chris H. Park, wrote.

  • US blockade of Iran ports to continue even during ceasefire.
  • Trump says closing strait risks Iran losing $500m daily.
  • Israel-Lebanon ceasefire talks set for Thursday.

WASHINGTON: President Donald Trump extended the US ceasefire with Iran to allow more time for peace talks, with Tehran silent on the decision early Wednesday.

Trump indefinitely pushed back the end of the two-week truce, crediting a request from mediator Pakistan and stressing the need to give Iran’s “fractured” leadership time to form a proposal. But he said the US blockade of Iran’s ports — a sticking point for Tehran — would continue.

In a Truth social post on Tuesday, the US president accused Iran of wanting to keep the Strait of Hormuz open “so they can make $500 Million Dollars a day,” which he said the Gulf nation would risk losing if it remains closed.

Trump insisted in the post that keeping a US blockade of the strait, a critical waterway for about a fifth of the world’s oil and natural gas exports, is vital for forging a deal with Iran.

“People approached me four days ago, saying, ‘Sir, Iran wants to open up the Strait, immediately.’ But if we do that, there can never be a Deal with Iran, unless we blow up the rest of their Country, their leaders included!,” Trump said in the post.

In an earlier social media post, Trump indicated that he had no desire to extend the ceasefire and had warned of a resumption of bombing when it expired.

“I have… directed our Military to continue the Blockade and, in all other respects, remain ready and able, and will therefore extend the Ceasefire until such time as their (Iran’s) proposal is submitted,” Trump wrote on social media.

Ahead of Trump’s eleventh-hour intervention, it had been unclear when the original ceasefire would expire, with Pakistan indicating it would end at 2350 GMT Tuesday.

This moment came and went with no reports of new military activity by Iran, which had said the ceasefire would end at 0000 GMT. Iran are yet to respond to Trump’s ceasefire extension.

The fate of peace talks hosted by Pakistan was left hanging in the balance following Trump’s announcement.

A White House official confirmed that Vice President JD Vance would not travel to Pakistan for talks on Tuesday as previously planned, pending the submission of an Iranian proposal.

Islamabad lockdown

Strict security measures were adopted on Tuesday in Islamabad which was virtually shut down, even as no Iranian-US meeting was fixed.

Prime Minister Shehbaz Sharif thanked Trump for extending the ceasefire, with UN Secretary General Antonio Guterres also welcoming it.

As the original ceasefire deadline drew in, Iran preemptively threatened to attack its Gulf neighbors’ oil production facilities if their territory was used to attack it once the ceasefire expired.

Since the first round of talks in Islamabad, Trump announced a blockade of Iranian ports, which US Treasury Secretary Scott Bessent said would remain in place.

“In a matter of days, Kharg Island storage will be full and the fragile Iranian oil wells will be shut in,” Bessent said in an X post Tuesday, adding that constraining Iran’s maritime trade will target its “primary revenue lifelines.”

He warned: “Any person or vessel facilitating these flows-through covert trade and finance risks exposure to US sanctions.”

The US Defence Department said Tuesday that its forces intercepted and boarded a “stateless sanctioned” vessel as part of Washington’s efforts. AFP has identified the vessel as one affiliated with Iranian activity.

Both sides have accused the other of ceasefire breaches.

‘Cursed ceasefire’

Residents in the Iranian capital who spoke to Paris-based AFP journalists say life has only worsened despite the truce.

“This cursed ceasefire has broken us,” said Saghar, 39. “I don’t know anyone around me who is doing well.”

Experts said Iran’s noncommittal public stance was an attempt to put pressure on Washington.

“The current standoff between the United States and Iran is no longer a clash of capabilities but rather a struggle of political endurance and bargaining leverage,” Daniel Byman of the Center for Strategic and International Studies wrote in a commentary.

Despite the ongoing uncertainty, stocks rose on Tuesday amid lingering hopes for a deal to end the conflict.

Israel-Lebanon talks

On another front in the war, Israel and Lebanon, which have no diplomatic relations, will hold fresh talks in Washington on Thursday, a State Department official told AFP.

A separate 10-day ceasefire was agreed between the two nations on Friday and included Hezbollah, whose rocket fire in support of Iran drew Lebanon into the wider Mideast conflict.

Sporadic violence has continued, and Israel’s military warned civilians against returning to dozens of villages in southern Lebanon.

Israeli attacks on Lebanon have killed at least 2,454 people since the start of the war, a Lebanese government body said in its latest toll.

Hezbollah said it launched an attack on northern Israel on Tuesday in retaliation for what it said were Israeli violations of the ceasefire, the first such claim since the truce began.
