Researchers suggest governments should prioritize adaption policies to address the negative impact of global warming, rather than focusing on reducing greenhouse gas emissions. The study highlights the importance of monitoring and modeling the impacts of climate change on Earth surface systems.
Research at the US Department of Agriculture found that no-till farming can reduce yield losses caused by climate change. The study simulated different climate factors on three cropping systems, finding declines in corn and millet yields over time. No-till management helped maintain wheat yields for up to 2075.
The Antarctic faces numerous challenges from human activity and climate change, including marine system impacts, invasive species, and pollution. The existing Antarctic Treaty System is being tested by growing tourism and resource use, highlighting the need for swifter decision-making and increased collaboration to conserve the region.
Researchers used stalagmites to reconstruct a history of the tropical West Pacific's climate over four glacial cycles, finding no evidence of a sudden shift in peak interglacial conditions following a key event. Instead, they found extreme drying in the tropics coincided with abrupt climate changes in high latitudes.
Researchers at the University of Exeter have developed a system to anticipate high-risk climate tipping points, providing early warning systems for devastating consequences. By analyzing observational data, scientists can identify signs of instability in climate systems, allowing for forewarning and adaptation.
A team of researchers from Kent State University has studied the history of drought in the Pacific Northwest over the past 6,000 years. They used sediment records and tree-ring data to find that drought duration increased in response to decadal oscillations driven by marine processes.
Researchers will collect and analyze data on carbon, nitrogen, and water movement to create models and evaluate crop management practices. The goal is to develop scenarios based on different practices and offer training for teachers and scientists to understand climate shifts and agriculture.
Researchers are analyzing sediment and water samples from four distinct environments, including cold-dry Antarctica, to test a hypothesis about the planet's past climate. The team hopes to find 'markers' or indicators unique to erosion in this type of climate.
Researchers developed a new technique to manage dams in the Columbia River basin for a warmer future climate. The approach reduced summer losses in hydropower due to climate change by about a quarter, while bolstering flows for fish and minimizing flooding.
Researchers have discovered that the deep ocean's temperature variability and circulation system are more complex than previously thought, leading to more accurate predictions of sea level rise and ice volume changes. The study uses a 3-D reconstruction of an ocean during a past warm period to gain insights into global climate dynamics.
Researchers propose a simple redesign of public buses to enhance cooling airflow through wide vents and adjustable roof designs. This design improvement increases the comfort zone of the bus from 11% to over 50%, benefiting all passengers.
Researchers analyzed the disappearance of the Laurentide Ice Sheet to shed light on how much the Greenland Ice Sheet will contribute to sea level rise. The study found that rapid melting can happen very quickly, with rates comparable to global sea level rise evidence for this interval derived from coral records.
A new study by CSIRO scientists warns that climate change will force environmental scientists to rethink their approach to conservation. Temperatures over Australia are projected to rise by about 1 ºC by 2030, and 1.8 ºC by 2070, relative to 1990 levels.
Researchers have identified nine key components of the Earth's climate system at risk of passing a tipping point, with some elements projected to undergo major transitions within the next 100 years. The study highlights the need for early warning systems and caution against complacency in addressing climate change.
The American Institute of Aeronautics and Astronautics has awarded NASA's Earth Observing System Program the 2006 Space Systems Award. The program, which comprises a series of Earth-observing satellites and an advanced data system, is being recognized for its outstanding achievements in global environmental monitoring.
Research at Ohio State University suggests that global climate changed dramatically 5,200 years ago, with severe impacts on emerging cultures. The team found evidence of sudden and severe climate shifts in ice cores, tree rings, and plant pollen records from around the world.
A study published in Nature found that changes in the North Atlantic Oscillation synchronize population fluctuations of caribou and muskoxen across Greenland. The researchers used local and global weather data to show cross-species synchrony, indicating the North Atlantic Oscillation's influence on their population dynamics.
Researchers at the University of Florida found that undercharged air conditioners use more electricity, leading to increased energy bills. They estimate that consumers can recover the cost of charging their systems in three months by simply topping off the charge.
The Pittsburgh Supercomputing Center will develop a six-teraflop terascale system, making it the most powerful available for public research. The system, part of NSF's PACI program, aims to facilitate progress in various fields, including climate change and weather forecasting.
NERSC's new IBM RS/6000 SP system will increase computing capabilities by over 400%, with a peak performance of 3 teraflops and 2,048 processors. The system will enable faster turnaround of results for users across the country, supporting large-scale scientific research in fields like climate modeling and materials science.
17-year-old Sasha Jones won a contest to name the first Earth Observing System satellite, Terra, which will study global climatic changes. The satellite's launch is set for July 15, 1999, and will enable new research into the planet's climate system.
