Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new MIT study finds.
More than half of the carbon sink in the world's forests is in areas where the trees are relatively young -- under 140 years old -- rather than in tropical rainforests, research at the University of Birmingham shows.
To help smallholder farmers adapt to climate change, scientists need to provide recommendations of crop varieties suitable to farmers' marginal and heterogeneous environments. However, existing on-farm approaches are difficult to scale. A novel scalable method using crowdsourced citizen science was employed on 12,409 trial plots in Ethiopia, India and Nicaragua. The results showed the potential of crowdsourced citizen science to improve variety recommendations and help farmers respond to climate change.
Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city.
Thomas Crowther, ETH Zurich identifies long-disappeared forests available for restoration across the world. In his AAAS session, Crowther describes how such an effort, could absorb as much as 135 gigatons of atmospheric carbon. Crowther will also describe data from thousands of soil samples collected by local scientists that reveal the world's most abundant population of soil organisms in arctic and sub-arctic regions and the most dominant populations of plants and animals in tropical regions.
Despite widespread infection, some frog populations are surviving a deadly disease that is the equivalent of mankind's Ebola virus. The reason -- genetic diversity. That's the finding of a new study published this week in the journal Immunogenetics. Anna Savage, an assistant professor of biology at the University of Central Florida, is the lead author of the study.
Tropical cyclones can become post-tropical before they dissipate, meaning they can become sub-tropical, extra-tropical or a remnant low pressure area. As Tropical Cyclone Gelena transitioned into a subtropical storm, NASA's Aqua satellite provided a visible image of the storm.
While previous studies showed elk often move into areas disturbed by fires or timber harvest to take advantage of new plant growth, that isn't happening in Wyoming's Sierra Madre Mountains, where elk strongly avoid beetle-killed areas in the summer.
Tropical Cyclone Oma continued to stay just west of Vanuatu in the Southern Pacific Ocean as NASA-NOAA's Suomi NPP satellite passed overhead and captured an image of the tropical storm.
Scientists from seven countries published an article on the study of the sources of black carbon (BC) emissions in the Arctic. BC aerosols are formed under incomplete fossil fuel combustion and biomass burning. Soot which is the main component of BC amplifies the melting of snow and ice cover, accelerating global warming. Based on the complex elemental and isotopic analysis the scientists revealed the seasonal contribution of various Arctic areas to BC emissions.
