Heat waves are hitting Antarctica too now
The world saw another year full of extreme weather events resulting from climate change in 2022, from intense storms to soaring temperatures and rising sea levels. Antarctica was no exception, according to new research published this week......»»
Using historical radar data to map changes in urban environments
Synthetic aperture radar (SAR) is a type of remote sensing from satellites that uses the reflection of radio waves to relay information about the surface of the earth. This reflection, or backscatter, is responsive to physical properties, such as rou.....»»
Most existing heat wave indices fail to capture heat wave severity, experts report
Even though climate change is bringing more frequent and severe heat waves, there is no standard, global way to measure heat-wave severity, and existing indices have different thresholds for defining dangerous heat-stress conditions......»»

Study yields new insights into the link between global warming and rising sea levels
A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the curre.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»

Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Extreme heat in India: A crisis on the rise
As global temperatures continue to rise, India is grappling with increasingly severe heat waves. As early as April, many Indian cities, including New Delhi, the capital, have experienced record temperatures above 115 degrees Fahrenheit......»»

Underwater mapping reveals new insights into melting of Antarctica"s ice shelves
An international research team—including scientists from the University of East Anglia (UEA)—deployed an unmanned submersible beneath the Dotson Ice Shelf in West Antarctica. The underwater vehicle, "Ran," was programmed to dive into the cavity.....»»
The climate is changing so fast, we haven"t seen how bad extreme weather could get
Extreme weather is by definition rare on our planet. Ferocious storms, searing heat waves and biting cold snaps illustrate what the climate is capable of at its worst. However, since Earth's climate is rapidly warming, predominantly due to fossil fue.....»»
Giant waves, monster winds and Earth"s strongest current: Why the Southern Ocean is a global engine room
