Severe spring thunderstorms frequently spawned tornadoes from the Gulf Coast north and eastward during the past seven days. NASA's IMERG data were used to estimate the amount of rain that fell from April 25 to May 2, 2016.
A new report by the University of Maryland School of Public Health and the Maryland Department of Health and Mental Hygiene details the impacts of climate change on the health of Marylanders now and in the future. Health impacts include increased risk of food and waterborne illnesses (caused by Salmonella and Campylobacter), hospitalization for heart attacks and asthma, and motor vehicle accidents.
The Arctic amplification phenomenon refers to the faster rate of warming in the Arctic compared to places farther south. Arctic amplification has been linked to a spike in the number of persistent cold spells experienced in recent years over Europe and North America.
Although the coastal regions of the Greenland Ice Sheet are experiencing rapid melting, a significant portion of the interior of that ice sheet has remained stable -- but a new study suggests that stability may not continue. Researchers found that very little of the snow and ice on the vast interior of the ice sheet is lost to the atmosphere through evaporation because of a strong thermal 'lid' that essentially traps the moisture and returns it to the surface where it refreezes.
A warmer climate usually also means that there is more precipitation, but there has been no increase in the amount of precipitation on the Greenland ice sheet. New research with participation of the Niels Bohr Institute shows that this is due to an insulating layer of air that forms near the surface during the winter, which insulates the ice sheet from the upper atmosphere and reduces both evaporation and precipitation.
Surface meltwater draining through and underneath Greenland's tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge.
A reduction in the amount of oxygen dissolved in the oceans due to climate change is already discernible in some parts of the world and should be evident across large regions of the oceans between 2030 and 2040, according to a new study led by the National Center for Atmospheric Research.
From a quarter to half of Earth's vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.
Using a new model, three Washington State University researchers predict that many forests across the US are ill-suited to withstand drought conditions likely to face the country in the coming century. Furthermore, in the Pacific Northwest, and across much of the US southern border, conditions may well require the development of new forest types not currently seen in the US.
In 1442, 50 years before Columbus 'sailed the ocean blue,' Shinto priests in Japan began keeping records of the annual freeze dates of a nearby lake. Along a Finnish river, starting in 1693, local merchants recorded the date the ice broke up each spring. These observations are among the oldest inland water ice records in human history, and now they are contributing to modern understanding of climate change.
