NASA data warns of surge in extreme weather events: Drought and floods intensifying globally
New data from
NASA
has revealed a dramatic and alarming increase in the severity and frequency of extreme weather events like droughts and floods worldwide. Using advanced satellite observations, researchers found that these events are not only occurring more often but are also lasting longer and impacting larger areas than ever before. The findings show that the number and intensity of these events have doubled in just the past five years compared to the 2003 to 2020 average. While the data isn't yet peer reviewed, scientists say it's a stark early warning that climate change is accelerating environmental disruptions faster than previously expected.
NASA's GRACE satellite finds alarming surge in weather extremes
The observations come from NASA's GRACE satellite, which monitors changes in Earth's water systems. Researchers were surprised to find that the pace of extreme weather events appears to be increasing even faster than global temperatures themselves. These events, such as long-lasting droughts and catastrophic floods, are closely linked to rising temperatures and are consistent with earlier climate predictions, but the speed of their intensification has shocked experts.
Scientists expressing concerns about global warming
While the dataset needs more years to confirm a definitive trend, several scientists have expressed concern. Dr Bailing Li, from NASA's Goddard Space Flight Center, stated that although causation can't be confirmed yet, the growing number of extreme events strongly points to global warming as a driver. Her colleague Dr Matthew Rodell described the trend as "certainly scary," noting that such changes could outpace society's ability to respond or adapt.
Water systems at the breaking point
NASA researchers measured events using a formula that includes affected area, duration, and wetness or dryness. They found that disruptions to water systems, one of the clearest consequences of climate change, are growing worse. A previous study in Nature Water had already warned that the world's water infrastructure is ill equipped to handle such fluctuations.
Global impacts and warnings
Experts from the UK Met Office and WaterAid say most cities and water utilities are unprepared for this new climate reality. Sudden transitions, called 'hydroclimatic whiplash,' from dry to wet conditions or vice versa are now more common and more damaging. These rapid shifts are affecting agriculture, infrastructure, human health, and biodiversity in unpredictable ways.
Extreme event to affect global economic planning, insurances and infrastructure
With the insurance industry relying on historical data to set premiums, the unpredictability of today's extreme weather could destabilize economic planning. The World Meteorological Organization has predicted that global temperatures will likely continue to rise, increasing the risk of devastating events in the next five years. Scientists and climate advocates are urging urgent investments in both emissions reduction and
climate adaptation strategies
to prepare for the changes already underway.

Delayed Again: Ax-4 mission launch put off to June 22
New Delhi: Indian astronaut Shubhanshu Shukla's Axiom-4 mission to the International Space Station has been postponed to June 22, to allow NASA to evaluate the operations on the orbital lab after the recent repairs in the Russian section, Axiom Space announced on Wednesday. The Axiom-4 mission, which marks the return to space for India, Hungary, and Poland, was earlier scheduled for lift-off from NASA's Kennedy Space Centre in Florida on June 19 onboard SpaceX's Falcon 9 rocket. "NASA, Axiom Space, and SpaceX are now targeting no earlier than June 22, for launch of the fourth private astronaut mission to the International Space Station, Axiom Mission 4," Axiom Space said in a statement. "The change in a targeted launch date provides NASA time to continue evaluating space station operations after recent repair work in the aft [back] most segment of the International Space Station's Zvezda service module," it said. The Axiom-4 commercial mission is led by Commander Peggy Whitson, with Shukla as mission pilot and Hungarian astronaut Tibor Kapu and Poland's Slawosz Uznanski-Wisniewski as mission specialists.

Voyager hits a 'Wall of Fire': NASA probe finds a furnace at the edge of the solar system
Voyager 1 has detected a shell of superheated plasma far beyond Pluto—offering a direct look at where the Sun's influence ends and interstellar space begins. From nearly 24 billion kilometres away, NASA's ageing Voyager 1 has sent back a signal confirming one of the most extreme discoveries yet: a narrow region near the heliopause where plasma has been heated to an astonishing 30,000 to 50,000 Kelvin. This marks the latest in a string of insights from the 48-year-old spacecraft. The heliopause, which defines the outer edge of the Sun's protective bubble known as the heliosphere, is where solar wind slams into material from interstellar space. It's not a wall in the traditional sense—but data show a sharp, localised zone of extreme discovery began with a spike in temperature data—despite the fact that Voyager 1's original plasma detector had failed years two other instruments still running—one monitoring cosmic ray hits, the other measuring the local magnetic field—spotted the clues. Solar wind ions dropped sharply. Meanwhile, cosmic ray counts surged and the magnetic field began to bend. That's when scientists realised what they were seeing. Researchers processed the data and saw evidence of a hot plasma shell, possibly just 1 astronomical unit thick. Hours later, Voyager 2—following its own path—picked up the same pattern, confirming the phenomenon wasn't a fluke.'It's a narrow, searing frontier,' said NASA Heliophysics scientists. And the spacecraft sailed right through no flame out there. No oxygen to feed one. But the searing temperature comes from the collision of the supersonic solar wind crashes into the slower-moving interstellar medium, magnetic turbulence and compression force particles into a higher energy state. That's where the heat comes from—particles zipping around at extreme speeds in a vacuum barely dense enough to warm short: it's a cosmic blast furnace, but with so little matter that Voyager's hull doesn't heat up.'She's been driving for five decades and just found the hottest rest stop in the universe,' quipped Suzanne Dodd, Voyager's flight director, after the data appeared on her Pasadena of the biggest surprises wasn't the heat—but the alignment of magnetic expected the magnetic field outside the heliopause to change direction entirely. But both Voyager probes have found that the magnetic field beyond the boundary runs almost parallel to the one within the heliosphere. NASA explained: 'An observation by Voyager 2's magnetic field instrument confirms a surprising result from Voyager 1: The magnetic field in the region just beyond the heliopause is parallel to the magnetic field inside the heliosphere.' That's upended existing models of the Sun's protective bubble. It suggests the heliosphere may be more closely connected to the galaxy's magnetic environment than previously assumed—and that our cosmic shielding from high-energy radiation might work in ways still not fully has important implications for protecting Earth and for long-duration human engineers remain in awe that Voyager 1 still data trickles in at just 160 bits per second. It takes 22 hours for a single message to arrive back at Earth's Deep Space Network.'That silence after you send a command is the longest coffee break imaginable,' said Todd Barber, Voyager systems ageing plutonium battery can now only support a few instruments. But NASA has juggled power usage carefully to keep the most valuable sensors running. Even at 48 years old, the probe continues to report back from the is already planning the next step. In 2026, the Interstellar Mapping and Acceleration Probe (IMAP) will launch to observe the heliopause from within. It aims to capture the same plasma flows that Voyager just measured, but with modern instruments and clearer further ahead is a proposed Interstellar Probe mission, designed to reach 400 AU in 50 years. Its goal? Map this fiery region—this 'invisible wall of fire'—in unprecedented of this future planning leans on Voyager's current 1 crossed into interstellar space on 25 August 2012. Its twin, Voyager 2, followed in 2018. But even now, these machines keep pushing the boundaries of what humanity knows about the edge of its own solar findings aren't just scientific curiosities. They help shape real-world plans to shield astronauts from cosmic radiation and inform how Earth's magnetic defences another dozen years, the last of Voyager 1's instruments may fall silent. But its final contribution—a message from the solar system's burning edge—might be its most now, it's still out there. Floating. Listening. Sending home the secrets of the stars.
