Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Scientific uncertainty has been described as a 'monster' that prevents understanding and delays mitigative action in response to climate change. New research by Professor Stephan Lewandowsky of the University of Bristol, and international colleagues, shows that uncertainty should make us more rather than less concerned about climate change.
Increasing heat is expected to extend dry conditions to far more farmland and cities by the end of the century than changes in rainfall alone, says a new study.
Changes in the sun's energy output may have led to marked natural climate change in Europe over the last 1000 years, according to researchers at Cardiff University.
If significant climate change occurs in the United States it may be necessary to change where certain foods are produced in order to meet consumer demand.
Ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments. Changes in air temperature and winter precipitation over the last five decades have affected the timing, duration and thickness of the ice cover on lakes in the Arctic.
NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.
The mystery of why life on Earth evolved when it did has deepened with the publication of a new study in the latest edition of the journal Science.
A mystery in the ocean near Antarctica has been solved by researchers who have long puzzled over how deep and mid-depth ocean waters are mixed. They found that sea water mixes dramatically as it rushes over undersea mountains in Drake Passage - the channel between the southern tip of South America and the Antarctic continent. Mixing of water layers in the oceans is crucial in regulating the Earth's climate and ocean currents.
Future warming from fossil fuel burning could be more intense and longer-lasting than previously thought. This prediction emerges from a new study by Richard Zeebe at the University of Hawai'i who includes insights from episodes of climate change in the geologic past to inform projections of man-made future climate change.
The floor of a NASA hangar and an adjacent laboratory in Southern California's high desert have been in constant motion this month as scientists prepare their instruments for installation on two of the agency's specialized science aircraft that will begin a major NASA airborne science campaign in early August.
Scientists found that in about one-third of global cropland, temperature and soil moisture have strong relationships to the yield of wheat and rice at harvest. For those two key crops, a computer model could predict crop failures three months in advance for about 20 percent of global cropland, according to the study, published July 21 in Nature Climate Change.
Archaeological and genetic evidence suggests that modern humans (the modern form of Homo sapiens, our species) originated in Africa during the Stone Age, between 30,000 and 280,000 years ago.
Fueled by industrial greenhouse gas emissions, Earth's climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years.
Earth's repeated flip-flopping between greenhouse and icehouse states over the past 500 million years may have been caused by volcanoes at particular spots where enormous amounts of carbon dioxide are released into the atmosphere.
Scientists say they've made a major breakthrough in understanding Earth's climate machine by reconstructing highly accurate records of changes in ice volume and deep-ocean temperatures over the last 1.5 million years.
Even minor volcanic eruptions can release enough aerosols into the atmosphere to affect global temperatures, thanks to a boosting effect from weather systems such as monsoons.
We're perhaps just decades away from the tipping point that could alter the planet irreversibly, an international group of scientists has warned.
A Danish physicist has concluded that the explosion of nearby supernovae has strongly influenced the development of life on Earth.
The European Space Agency (ESA) has lost contact with Envisat, its flagship Earth-observing satellite.
