Arctic permafrost thaw plays greater role in climate change than previously estimated

Scientists Make First-Ever Observation of Warm Water Undercutting Antarctica’s ‘Doomsday Glacier’

Gif: David Holland/NYU & NYU Abu DhabiThe climate crisis is causing ice in Antarctica to melt faster than at any other time in recorded history. And scientists just found another troubling sign for Antarctic ice. Record warm water is surging under an Antarctica glacier that’s fate is intertwined with the millions of people who live…

Earth about to enter 30-YEAR ‘Mini Ice Age’ with -50C temperatures in coldest regions, scientists warn

EARTH could face frosty weather and biting snow storms over the next 30 years as an ominous “solar minimum” grips the planet, a scientist has warned. The cold snaps – caused by the Sun entering a natural “hibernation” – threaten to trigger food shortages as temperatures slump across the planet, experts say. Earth is bracing…

Robotic submarine snaps first-ever images at foundation of notorious Antarctic glacier

The first-ever images have been taken of the grounding zone of Thwaites Glacier in Antarctica. The grounding line just behind it is an integral factor in the glacier’s stability or lack thereof. It is tied to the fate of global sea-levels. At top, the glacier, at bottom, the seafloor. Credit: International Thwaites Glacier Collaboration /…

Oceanographers predict increase in phytoplankton by 2100

Credit: CC0 Public Domain A neural network-driven Earth system model has led University of California, Irvine oceanographers to a surprising conclusion: phytoplankton populations will grow in low-latitude waters by the end of the 21st century. The unexpected simulation outcome runs counter to the longstanding belief by many in the environmental science community that future global…

These are the climate tipping points we simply can’t cross

Eric Lafforgue/Art In All Of Us/Corbis via Getty Images In 2009, scientists from the Stockholm Resilience Centre identified nine key environmental red lines that could be catastrophic for life on Earth if crossed. Climate change is one, but that’s not the only “planetary boundary” we’re in danger of violating.Human activities are reshaping the environment in…
