Researchers studied ancient sediment samples to understand Antarctica's past environmental changes and their impact on global climate. The findings suggest a complex relationship between ocean circulation patterns and ice sheet stability, contradicting previous desert-like conditions in the region.
A study led by Colorado State University scientists reveals that human-caused global changes, such as land-use change and nitrogen deposition, are expected to drive biodiversity loss between now and 2100. The research identifies five primary drivers of global change and assesses their impact on terrestrial and freshwater ecosystems.
Integrated Regional Assessment framework considers human activities, climate change impacts, economic responses, and social implications to inform local decisions. The approach aims to mitigate problems and create jobs in regions heavily dependent on coal production.
The Arctic Oscillation is linked to warmer winters in Scandinavia and Siberia, stratospheric ozone layer thinning, and altered surface winds. This phenomenon could be part of human-induced climate change, according to researchers.
The Climate Impacts Group at the University of Washington predicts significant climate changes in the NW region by 2050, including warmer temperatures, wetter winters, and shrinking snowpack. The report highlights the need for regional water management and planning to mitigate these impacts.
A study on Isle Royale National Park found that wolves' increased hunting efficiency in snowy winters led to a decline in moose populations, reducing browsing pressure on balsam fir saplings. This cascade of ecological responses highlights the potential impact of apex predators' behavioral adaptations to climate change.
A UNC-CH study explains that variations in Earth's orbit over tens of thousands of years account for the timing of ice ages, providing a more complex understanding of long-term climate change. This new research confirms a theory from the 1920s and sheds light on predicting future global climate change.
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.
The regional climate change model suggests a 50% decrease in snow cover over Washington state and warmer temperatures, while also increasing winter precipitation. The impacts on water resources could be significant, with less snow melt in the spring and reduced stream flow for irrigation.
Researchers can now forecast long-term climate cycles, such as the El Niño Southern Oscillation and Pacific Decadal Oscillation. By understanding these cycles, policymakers can develop strategies to lessen climate-related effects, potentially ensuring cultural survival.
A Colorado State University study found that warmer nights are extending the growing season, favoring cool-season grasses and weeds over native warm-season plants like blue grama grass. This shift could lead to a decline in blue grama, which is essential for the shortgrass steppe ecosystem.
Researchers found that global climate change could lead to dramatic increases in California wildfires and economic losses. The study analyzed the potential effects of climate change on wildfires in California and found that changes would occur despite enhanced fire suppression resources.
Research by University of Cincinnati geologist Thomas Lowell reveals that the ice sheet advances over land marched in step with the iceberg calving events over the ocean. The findings suggest that both land and sea events are responding to global cooling, reinforcing the pattern rather than initiating the change.
The Duke scientists analyzed past climate changes and found that the region rapidly changed with even short-term climate fluctuations, making it susceptible to drastic ecological changes. The researchers expect that global warming will significantly increase temperatures worldwide over the next century, leading to shifts in air masses ...
The Global Change and Terrestrial Ecosystems Project and the Land-Use/Cover Change Program present experimental and theoretical findings on global environmental changes. The conference aims to document and understand global land-use and land-cover change, its relationship to climate and biogeochemistry.
Experimental data suggests that elevated CO2 may not stimulate agricultural yield as much as previously thought, with potential losses due to temperature increases and increased pest pressure. Computer models are being used to simulate the effects of climate change on crop yields in various regions.
Penn State researchers investigate climate change's effects on the Susquehanna River Basin, examining vulnerabilities to flooding, waterborne diseases, and policy decisions. They find that effective measures like increased filtration, boiling water, and balanced expenses can mitigate these risks.
A University of Michigan model reveals that carbon and sulfur emissions can cool the planet by up to -4.4 Wm-2, potentially offsetting human-caused warming. However, the models' uncertainty due to poorly known estimates for natural aerosol sources may limit the findings.
African climate has abruptly turned from wet to dry in short time spans, every 1,500 years, according to Columbia University paleoclimatologist Peter deMenocal. This cycle matches a pattern of abrupt changes in the North Atlantic region and points to a persistent, naturally occurring cycle of climate change.
A new study has confirmed that the Earth's surface temperature has increased by about 1 degree C over the last five centuries, with the majority of this warming happening in the last 100 years. The study used data from 300 underground boreholes across four continents to find a global average temperature increase since 1900.
A Columbia University scientist warns that global warming could cause the abrupt collapse of ocean currents, sending European temperatures plummeting by 20 degrees Fahrenheit within 10 years. This could lead to a drastic change in climate, with devastating consequences.
A new study found significant climatic change in the Arctic without human influence, contradicting previous assumptions. The research, led by Dr. Marianne Douglas, analyzed diatom assemblages in lake and pond sediments, revealing warming trends that began in the 1840s and ended the Little Ice Age.
A new RFF issues brief highlights the potential impacts of climate change on agriculture, with estimates suggesting a modest reduction in grain production in developing countries and improvements in industrialized nations. However, the author notes that regional changes are highly uncertain due to varying climate models.
A new RFF issues brief highlights the potential impacts of climate change on water supplies, including increased precipitation, evapotranspiration, and extreme weather events. The report emphasizes the need for more efficient water management and use to mitigate these effects.
A half-million-year record of ostracodes shows that biodiversity declines during glacial periods and increases during interglacial periods. Global climate change may further affect the richness of life on Earth beyond habitat degradation.
Researchers investigate how climate change affects vulnerable populations, including access to public water supply and education levels. The study aims to understand the potential regional-scale effects of climate change on social groups in specific regions.
Researchers investigated urbanized watersheds in four US regions over 50 years, comparing stream flow data with population growth. They found that higher population densities led to increased stream flow despite lower precipitation levels.
Researchers found the ancient Sahara was much wetter 12,000 to 5,000 years ago, with stronger summer monsoons producing more vegetation and increased water content in the soil. The vegetation and soil changes enhanced the effects of orbital shifts, leading to a 10% increase in annual precipitation.
The program aims to increase understanding of climate change policy issues, focusing on economic and environmental consequences, policy design, interactions with other policies, equity and efficiency, and development of analytical tools. RFF will conduct research projects and issue papers on selected topics.
Experts argue that global change research should focus on predicting rainfall patterns rather than temperature changes. Changes in rainfall can have significant effects on human activities and structures, such as road design and agriculture. By prioritizing rainfall prediction, researchers can help mitigate severe floods and droughts.
