The Arctic’s Permafrost-Obsessed Methane Detectives
The Far North is thawing, unleashing clouds of planet-heating gas. Scientists rely on an arsenal of tech to sniff out just how nasty the problem is......»»
Trees reveal climate surprise: Microbes living in bark remove methane from the atmosphere
Tree bark surfaces play an important role in removing methane gas from the atmosphere, according to a study published 24 July in Nature......»»
Mathematicians team up with geophysicists to improve models that predict changes in sea ice
Dartmouth researchers are using computational mathematics and machine learning to develop models that better predict sea ice thickness in regions of the Arctic......»»
Methane emissions are the low-hanging fruit of the climate transition
Methane is well known for coming from ruminants digestive system. What is less known is its important role in current climate change and what we could do to drastically reduce our emissions......»»
Sea ice"s cooling power is waning faster than its area of extent, new study finds
As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research led by University of Michigan scientists......»»
Study detects the largest methane leak ever recorded in an oil well
An international team of scientists led by Dr. Luis Guanter, UPV professor and head of the LARS Group of the Institute of Water and Environmental Engineering of the Universitat Politècnica de València (IIAMA-UPV), has documented the largest methane.....»»
Melting ice no guarantee of smooth sailing in fabled Arctic crossing: Study
Melting sea ice in the fast-warming Arctic Ocean is not making it easier for sailors to navigate a legendary shortcut between Europe and Asia despite popular belief, scientists said Thursday......»»
Accepting uncertainty in sustainable fisheries is essential in a rapidly changing Arctic, says researcher
Climate change is making it almost impossible to decide how much, where and what to sustainably fish as the fate of future fisheries is becoming increasingly uncertain. This is leading to a slow process or inaction in adapting fisheries and their man.....»»
AI model harnesses physics to autocorrect remote sensing data
Turbulence, temperature changes, water vapor, carbon dioxide, ozone, methane, and other gases absorb, reflect, and scatter sunlight as it passes through the atmosphere, bounces off the Earth's surface, and is collected by a sensor on a remote sensing.....»»
Investigating variation in the permafrost active layer over the Tibetan Plateau from 1980 to 2020
The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more sensitive to global warming. The active layer is a cruc.....»»
Methane flux in North Sea varies with tides, study shows
Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the sea floor can be just easily three times as much or as little, depending on the tide.....»»
Canadian wildfire smoke dispersal worsened by coincident cyclones, study suggests
Wildfires are unplanned and unpredictable threats to Earth; while we may intuitively relate them to extreme heat at lower latitudes, they are known to occur in Arctic regions, such as those recently ravaging Russia......»»
The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities
In the summer of 2022, a research cruise detected a massive harmful algal bloom (HAB) in the Bering Strait region of western Alaska. This expedition provided a dramatic example of science utilizing new technology to track a neurotoxic HAB, and effect.....»»
Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming......»»
Polar warming may be underestimated by climate models, ~50 million year old climate variability suggests
Polar regions are known to be warming at an enhanced rate compared to lower latitudes, with the Intergovernmental Panel on Climate Change citing a ~5 °C increase in air temperature over Arctic land masses during the 20th century and the highest rate.....»»
Exploring the radiative effects of precipitation on Arctic amplification and energy budget
One of the key metrics for climate modeling is radiative forcing. Most climate models, including the general circulation models (GCMs), focus on the effects of different atmospheric factors on radiative forcing. However, there are still large uncerta.....»»
Dubai rowers to brave Arctic to highlight plastics pollution
At an indoor pool in Dubai, three rowers battle artificial rain and simulated waves as they train for an Arctic voyage intended to highlight the perils of marine pollution......»»
Zombie Fire Season Is Here in the Arctic
Every year, peatlands in the Arctic suddenly ignite. Smoldering subterranean fires from the previous summer were thought to be to blame, but now modeling suggests a worrying new cause......»»
NASA mission flies over Arctic to study sea ice melt causes
It's not just rising air and water temperatures influencing the decades-long decline of Arctic sea ice. Clouds, aerosols, even the bumps and dips on the ice itself can play a role. To explore how these factors interact and impact sea ice melting, NAS.....»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
NASA Langley researchers are heading to the Arctic. Here"s why that matters.
NASA Langley researchers are heading to the Arctic Ocean to study the habitat's effect on climate worldwide......»»
