In the course of the last few decades, the oxygen concentration levels in aquifers in the Swiss Plateau have dropped irregularly. Results of the National Research Programme "Sustainable Water Management” (NRP 61) suggest that the irregular decrease might be related to various degrees of silting in watercourses.
It is difficult to forecast heavy precipitation events accurately and reliably. The quality of these forecasts is affected by two processes whose relative importance has now been quantified. The French researchers have shown that these processes should be taken into account in low wind speed events. Their findings should help forecast these events, which repeatedly cause significant damage.
A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. The results solve a long-standing debate and reveal how pollution plays into climate warming. The work can also provide a gauge for the accuracy of weather and climate models.
A study of 2300 species of mammals and 6700 species of birds helps explain why there are more species in the tropics than at higher latitudes. Researchers found that while the tropics harbor more species, the number of subspecies increases in the harsher environments typical of higher latitudes. The results suggest that the latitudinal diversity gradient may be due higher species turnover -- speciation counterbalanced by extinction -- towards the poles than near the equator.
In a dense fog, a Russian Rockot rocket on 22 November 2013 cleared the launchpad of the Baikonur Cosmodrome on schedule at 13:02:15 CET. In the tip of the rocket: three identical satellites to measure Earth's magnetic field. A good hour and a half later, at 14:37:48 CET, the report of success: all three satellites separated seamlessly from the carrier rocket and the ground stations Kiruna (Sweden) and Longyearbyen /Svalbard (Norway) were able to establish radio contact with them.
The flight season timing of a wide variety of butterflies is responsive to temperature and could be altered by climate change, according to a new study that leverages more than a century's worth of museum and weather records.
A new study may help improve seasonal forecasts in the Southeastern US by providing a new Bayesian statistical "framework" that meteorologists can use to predict the likely intensity of rainfall for the coming summer.
Maximizing returns on financial investments depends on accurately understanding and effectively accounting for weather and climate risks, according to a new study. The purpose of the study was to assist with societal decision-making by examining the implications of climate variability and change on near-term financial investments. The study also found that weather events create and exacerbate risks to financial investments.
Unlike long-term climate predictions, forecasts about the next twenty to fifty years are fraught with major uncertainties. In spite of this, however, ETH-Zurich scientists have now managed to make projections about the future distribution of heat and precipitation extremes.
Scientists have developed a new computer modeling technique that offers the promise, for the first time, of producing continually updated daylong predictions of wildfire growth throughout the lifetime of long-lived blazes. The technique combines detailed computer simulations with newly available satellite observations.
People who live in the southeastern United States should begin to prepare for more drastically changing weather conditions -- everything from heat waves to poorer air quality -- caused by climate change, according to a new book.
Scientists say they have found "missing heat" in Earth's climate system, casting doubt on suggestions that global warming has slowed or stopped over the past decade. The new research shows that the Arctic is warming at about eight times the pace of the rest of the planet.
As climate changes get more pronounced, people everywhere will have to adjust. In this week's issue of the journal Science, an international group of researchers urge the development of science needed to manage climate risks and capitalize on unexpected opportunities.
Total deforestation of the Amazon could mean 20 percent less rain for the coastal Northwest and a 50 percent reduction in the Sierra Nevada snowpack, resulting in water and food shortages, and a greater risk of forest fires, new research shows.
New research will help you every morning with the surf report. It is estimated that 75 per cent of waves across the world are not actually generated by local winds. Instead, they are driven by distant storms which propagate as swell.
A key instrument that will fly on the Geostationary Operational Environmental Satellite-R (GOES-R) spacecraft, NOAA's next-generation of geostationary satellites, is cleared for installation on the spacecraft. The Advanced Baseline Imager, or ABI, is GOES-R's primary instrument for scanning Earth's weather, oceans, and environment and is a significant improvement over instruments on NOAA's current geostationary satellites. The ABI will offer faster imaging with much higher detail. It will also introduce new forecast products for severe weather, volcanic ash advisories, fire and smoke monitoring and other hazards.
Scientists correlated fMRI findings with the negative impact of outdoor temperature on cognitive functioning in multiple sclerosis. This study in Brain Imaging & Behavior corroborates the group's previous study that established that people with MS performed worse on cognitive tasks during warmer outdoor temperatures. This new study extends previous research by demonstrating a link between brain activity and outdoor temperature.
