Heat trapped by greenhouse gases is raising ocean temperatures faster than previously thought, concludes an analysis of four recent ocean heating observations. The results provide further evidence that earlier claims of a slowdown or 'hiatus' in global warming over the past 15 years were unfounded.
How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.
A new study combining data from citizen scientists and weather radar stations is providing detailed insights into spring bird migration along the Gulf of Mexico and how these journeys may be affected by climate change. Findings on the timing, location, and intensity of these bird movements have been published.
As human activities cause the Earth's temperature to increase, reliable, well-studied weather patterns like the Madden-Julian Oscillation will change too, say researchers.
Researchers have found that current breeding programs and cultivar selection practices do not provide the needed resilience to climate change.
Weather forecasters may be looking in the wrong place when working to issue tornado warnings, new research has demonstrated.
The mass death of flying foxes in extreme heat in North Queensland last month underscores the importance of wildlife research released today. The new research sheds light on how various species have responded to major climate events.
In order to analyse climate change or provide information about natural hazards, it is important to gather knowledge about the rain. Better knowledge of precipitation and its distribution could, for example, help protect against river flooding. A new approach uses, for the first time, information contained in radar signals from navigation satellites to detect rain over the sea. The technology could help to monitor atmospheric precipitation better than before.
Scientists have shared early results from a trio of studies that aim to improve models designed to guide agricultural practices for reducing the risk of nitrogen and phosphorous farm runoff. Such runoff leads to the growth of toxic algae in waterways.
An increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.
A new study shows that Midwest agriculture is increasingly vulnerable to climate change because of the region's reliance on growing rain-fed crops.
More and more rainfall extremes are observed in regions around the globe -- triggering both wet and dry records, a new study shows. Yet there are big differences between regions: The central and Eastern US, northern Europe and northern Asia have experienced heavy rainfall events that have led to severe floods in recent past. In contrast, most African regions have seen an increased frequency of months with a lack of rain.
Researchers mapped the changes in snow mass from 1982 to 2016 onto a grid of squares 2.5-miles on a side over the entire contiguous U.S. Grid size for previous studies was about 40 miles on a side. Since 1982, some parts of the West have a 41 percent reduction in the yearly maximum mass of snow.
NOAA's annual report card on the Arctic, released today, shows that the Arctic region experienced the second-warmest air temperatures ever recorded; the second-lowest overall sea-ice coverage; lowest recorded winter ice in the Bering Sea; and earlier plankton blooms due to early melting of sea ice in the Bering Sea.
Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years.
The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a new study, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.
Atmospheric scientists have documented a rare firenado, finding a number of factors that combined at just the right time and place to catalyze the deadly Carr Fire in Northern California. These observations may help forecasters and scientists identify -- and potentially warn - for future destructive fire-generated vortices.
The warming of the Indian Ocean, caused by global climate change, may be causing a slow decline in wind power potential in India, according to a new study.
The pattern of uneven sea level rise over the last quarter century has been driven in part by human-caused climate change, not just natural variability, according to a new study.
Researchers examined how 18 years of drought affect the billions of vital bacteria that are hidden in the soil beneath our feet. The results show that this type of extreme weather determines how soils respond to future climate change.
