How Climate Change And Warming Oceans Led To Kolkata's Historic Downpour
As Kolkata begins to mop up after one of its worst deluges in recent memory, scientists warn that such extreme weather events are no longer anomalies - they are becoming the new normal.

2025 Witnessed World's Third-Hottest August On Record
Devastating wildfires and blistering heatwaves during the world's third-hottest August on record underscored the urgency of tackling climate change and preparing for its deadly consequences, the European global warming monitor said Tuesday.

Sea Ice To Ocean Currents, Antarctica Is Undergoing Abrupt Changes
Melting sea ice allows oceans to warm more rapidly, which melts more sea ice. Once triggered, they can be difficult or even impossible to reverse on timescales meaningful to humans.

Atlantic Hurricane Season Sets Peak Record As Storm Erin Threatens US Coast
Hurricane Erin's massive footprint battered Caribbean islands with heavy gusts and downpours on Monday, as it threatened rip currents and flooding along the US East Coast later this week, even without a predicted landfall.

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

Explained: Why India's Monsoons Are Now Deadlier And More Unpredictable
Monsoon rainfall is becoming more erratic, with intense downpours followed by dry spells. This variability affects agriculture, water systems, and disaster preparedness.

From Ice Sheets To Oceans: The Climate Tipping Points That Worry Scientists
A climate tipping point is a critical threshold where a small environmental change can lead to dramatic and often irreversible shifts.

Global Antarctic Research Declines Amid Growing Climate Crisis
Ice loss in Antarctica and its impact on the planet - sea level rise, changes to ocean currents and disturbance of wildlife and food webs - has been in the news a lot lately.

Warm Seas Fuel Dangerous 'Weather Bomb' Set To Hit New South Wales Coast
Right now, a severe storm likely to be the first significant east coast low in three years is developing off the coast of New South Wales.

Our Oceans Are In Trouble: Here's How To Take Action Beyond The Outrage
Our oceans are in trouble. Catches from many of the world's fisheries are declining, with some fishing practices destroying enormous areas of the sea bed.

Earth Trapping More Heat Than Expected, Rate Doubled In 20 Years
How do you measure climate change? One way is by recording temperatures in different places over a long period of time. While this works well, natural variation can make it harder to see longer-term trends.

Earth’s Oceans Enter Danger Zone Due to Rising Acidification, New Study Warns
A new 2025 study published in Global Change Biology shows Earth’s oceans may have entered a dangerous acidification zone in 2020. As CO₂ emissions increase, marine ecosystems are degrading, threatening biodiversity, food security, and coastal economies. Scientists call it a ticking time bomb for the environment and society.

Southwest Pacific Hit By Unprecedented Marine Heat Waves In 2024: United Nations
Unprecedented heat waves in the Southwest Pacific affected more than 10% of the global ocean surface in 2024, damaging coral reefs and putting the region's last remaining tropical glacier at risk of extinction, the UN's weather body said on Thursday.

In Canada Lake, Robot Learns To Mine Without Disrupting Marine Life
Three robotic arms extended under the water in a Canadian lake, delicately selecting pebbles from the bed, before storing them back inside the machine. The robot was made by Impossible Metals, a company founded in California in 2020.

NASA’s SWOT Satellite Reveals Big Impact of Small Ocean Currents and Waves in n Marine Ecosystems
NASA’s SWOT satellite, in collaboration with CNES, reveals how submesoscale ocean features just a mile wide drive vital vertical circulation. These small currents transport heat, carbon, and nutrients, profoundly influencing marine ecosystems and climate systems. The mission’s high-resolution data is reshaping how scientists model ocean-atmosph...
