Ice Giant Shatters: World Largest Iceberg A23a Breaks Up Posing Risk to Penguins, Ships and Climate Stability

Breaking News, Climate Actions, Environment

The world’s largest iceberg, A23a is disintegrating into thousands of smaller ice chunks, posing environmental and navigational threats in the Southern Ocean. NASA’s Aqua satellite, using its MODIS instrument, captured striking images of this slow-motion collapse near South Georgia Island, where the iceberg is currently grounded. A23a with a surface area once estimated at 1,200 square miles roughly the size of South Georgia Island has been slowly breaking apart via a process called "edge wasting." Since becoming lodged again in March, the massive sheet has already lost nearly 200 square miles of ice. NASA reports that the largest fragment so far, dubbed A23c, spans around 50 square miles, while many other splintering pieces still stretch over a kilometre across, making them dangerou...

Powerful Solar Flares Trigger Global Radio Blackouts, Signal Intensifying Sun Activity

Breaking News, Environment, Space

The sun erupted with two massive solar flares early Wednesday, including the strongest of 2025 so far an X2.7-class flare causing widespread shortwave radio blackouts across at least five continents. The event came just a day after NASA’s Solar Dynamics Observatory captured another major eruption, an X1.2-class flare, in a dramatic image. Solar flares are categorized by intensity, with X-class being the most powerful. Wednesday’s solar storm peaked at 4:25 a.m. ET, delivering a strong burst of plasma and charged particles into space. This flare followed an M5.3-class flare several hours earlier, further underscoring the heightened solar activity. According to NOAA’s Space Weather Prediction Center, these intense flares disrupted high-frequency radio communications in parts of Nor...

World coastal Cities Sinking NASA Warns of Accelerated Sea Level Rise

Breaking News, Climate Actions, Environment

A new NASA-led study has revealed that many of the world’s coastal cities are sinking, making them more vulnerable to rising sea levels than previously thought. Researchers found that in some regions, land is subsiding so rapidly that flood risks could double by 2050, far exceeding earlier projections. Published in Science Advances, the study used satellite data from ESA's Sentinel-1 mission to track vertical land motion along California’s coast from 2015 to 2023. The findings show that in areas like San Francisco Bay, land is sinking by over 10 millimeters per year, potentially leading to more than 45 centimeters of local sea level rise by mid-century. While melting ice caps and climate change have long been blamed for rising seas, the study highlights that human activities such as ...

World Sets Record January Heat Despite La Nina Scientists Debate Accelerating Global Warming

Breaking News, Climate Actions

The world warmed to a new monthly heat record this January, despite cooling factors like a La Nina event and an abnormally chilly United States, according to the European climate service Copernicus. This surprising temperature rise is sparking debate among scientists, with some arguing that global warming is accelerating. Copernicus reported that January 2025 was 0.09 degrees Celsius warmer than January 2024, the previous hottest January on record. It was also 1.75 degrees Celsius warmer than pre-industrial levels. This marks the 18th month out of the last 19 in which the world hit or surpassed the 1.5-degree warming threshold set by the Paris Agreement. However, scientists only consider the threshold breached when temperatures stay above it for 20 consecutive years. Copernicus has t...

Bennu Asteroid Potential Impact How a Collision Could Trigger Global Climate Crisis and Food Insecurity

Breaking News, Climate Actions, Space

Bennu, a near-Earth asteroid, is classified as a "rubble pile" object a loose collection of rocky materials rather than a solid mass. It currently makes its closest approach to Earth every six years, coming within about 186,000 miles (299,000 km). Scientists estimate there is a one-in-2,700 chance that Bennu could collide with Earth in September 2182. If Bennu were to strike our planet, the consequences would be catastrophic. New research based on computer simulations has outlined the likely effects of such an impact, which would include immediate devastation and long-term global disruptions to climate, atmospheric chemistry, and photosynthesis. These disruptions could last for three to four years, according to the study published in the journal Science Advances. Lan Dai, a postdocto...

Doomsday Rock? NASA Flags Asteroid That Might Strike Earth in 2032

Breaking News, Disasters, Space

NASA has identified an asteroid, 2024 YR4, that carries a 1-in-83 chance of colliding with Earth on December 22, 2032. If the asteroid, estimated to be 130 to 300 feet in diameter, strikes a densely populated area, it could unleash devastation equivalent to 8 megatons of TNT 500 times the power of the Hiroshima bomb. Discovered on December 27, 2024, by the NASA-funded ATLAS station in Chile, 2024 YR4 quickly appeared on NASA’s Sentry risk list, which tracks potentially hazardous space rocks. However, experts emphasize that early impact probabilities often change with further observations, and there is still a 99% chance the asteroid will miss Earth. NASA continues to monitor the asteroid’s trajectory closely, collecting more data to refine its impact risk. While past asteroids have b...
