Researchers found that carbon dioxide from human activities primarily ends up in the subtropical ocean, rather than the cold Southern Ocean. This new understanding challenges previous models and highlights the complexity of global ocean carbon sequestration.
A study using satellite instruments reveals that the atmosphere has gotten warmer and wetter over the past decade. Water vapor levels in the atmosphere have increased by 2%, indicating a significant change in climate dynamics.
A new study reveals that over 600 areas in the Gulf of Mexico experience natural oil seeps, releasing twice an Exxon Valdez spill worth of oil annually. The oil breaks down into carbon dioxide and is harmless to marine animals, with surface tension spreading it thinly across the ocean surface.
Scientists have found that sea surface temperatures in Atlantic, Pacific, and Western Pacific oceans significantly impact rainfall patterns in the Amazon. Sea surface temperatures play a crucial role in predicting drought or floods in the region.
NASA scientists presented new findings on ozonesonde data, glaciers, Mars impact features, Landsat-7 mission performance, tropical landscapes, and more. The results include insights into ozone layer changes, ice stream movements, and buried impact basins on Mars.
The Landsat 7 spacecraft has acquired over 50,000 scenes of the Earth's surface, providing detailed images of natural disasters, unique weather patterns, and glacial changes. The satellite's data will support global change research and inform decision-making about environmental issues.
Researchers use Canadian Radarsat satellite data to uncover tributaries feeding giant ice streams, changing understanding of Antarctic ice sheet dynamics. High-resolution radar maps reveal complex patterns and fast-flowing glaciers, shedding light on the continent's past and potential sea level rise
A new study using NASA's Sea-viewing Wide Field-of-View Sensor (SeaWiFS) reveals that El Niño dramatically reduced the amount of carbon dioxide normally released into the atmosphere by the equatorial Pacific Ocean. Chlorophyll levels also plummeted during this time, followed by a massive bloom of microscopic algae.
Arctic sea ice has been declining at an alarming rate, with a downward trend of 37,000 square kilometers per year over the past 19.4 years. A new study suggests that human-induced global warming may be contributing to this decline.
Researchers used a computer climate model to find that vegetation interactions significantly drive the Sahel region's drought. The study suggests that natural vegetation causes enhanced drying, leading to cooler climates and reduced rainfall.
Scientists from NASA and Colorado State University present research on the link between water vapor and climate change, highlighting its significant impact on global warming. Water vapor's unique molecular structure and potential heat stored within it influence storm formation and atmospheric circulation.
NASA scientists find that jet aircraft add a few tens of parts per trillion of nitrogen oxides to the atmosphere, increasing ozone levels. However, the impact is too small to detect, but as air traffic increases, understanding these effects becomes crucial for global climate research.
The University of Hawai'i computer system uses Geostationary Operational Environmental Satellites (GOES) to detect heat from fires on the ground, providing early warnings for forest services. The system has been tested in Southern California and will soon monitor fires across the West Coast, including California, Oregon, and Washington.
Scientists create a new 'drought map' using National Oceanic and Atmospheric Administration (NOAA) satellite data to identify areas hardest hit by the drought. The map compares current surface temperature measurements to average temperatures over the last 10 years, showing whether an area has a normal, low, medium or high drought index.
A landmark study assessing New York City's metropolitan area for climate change challenges has been presented by Cynthia Rosenzweig. The project pairs scientists with local governments to inform decisions on aging roads, public health, and coastal erosion.
Northern Hemisphere winters have warmed by up to nine degrees Fahrenheit over the last 30 years, likely due to human activities increasing greenhouse gases. Warmer winters will bring more wet weather to Europe and Western North America.
Researchers have uncovered clues to the cause, timing and evolution of the massive East Asian summer monsoon. The study found a connection between the disastrous 1998 Yangtze River flood and the timing and strength of the summer monsoon.
The Terra mission marks a new era in global change research, providing unprecedented data to study climate change. The workshop brings together leading scientists to discuss new findings and challenges in the field.
