I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#How to tackle climate change, food security and land degradation” A farmer tends rice fields in Yen Bai, Vietnam, where balancing goals for sustainable development and management of ecosystems is challenging. Options like improved cropland management, increasing soil carbon, agroforestry, integrated water management and fire management are all low trade-off land management practices that can…
“#Predicting fire risk” Oak Ridge National Laboratory developed a method that uses machine learning to predict seasonal fire risk in Africa, which contains about 70% of the global burned area, shown in red.

“#Conservation agriculture increases carbon sequestration in extensive crops” Crops sown under no till farming. Credit: University of Cordoba Agricultural activity is responsible for about 12% of the total emissions of greenhouse gases in Spain. Nevertheless, adopting good agricultural practices can help reverse this situation, by increasing the sequestration of organic carbon in soil. With the…
“#Agriculture: A climate villain? Maybe not!” Per Frankelius, senior researcher, Linkoping University. Credit: Per Frankelius/LiU The UN’s Intergovernmental Panel on Climate Change (IPCC) claims that agriculture is one of the main sources of greenhouse gases, and is thus by many observers considered as a climate villain. This conclusion, however, is based on a paradigm that…
“#A chemical cocktail of air pollution in Beijing, China during COVID-19 outbreak” Changes in primary aerosols, gaseous precursors, and secondary aerosols during the COVID-19 outbreak and Chinese New Year holiday. Credit: Li Hao The novel coronavirus disease (COVID-19) spreads rapidly around the world, and has limited people’s outdoor activities substantially. Air quality is therefore expected…
“#NASA finds powerful storm’s around Tropical Storm Cristina’s center” On July 7 at 4:10 a.m. EDT (0810 UTC) the MODIS instrument that flies aboard NASA’s Aqua satellite revealed two areas of very powerful thunderstorms (yellow) around Cristina’s center where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius).

“#Engineers use electricity to clean up toxic water” Credit: CC0 Public Domain A team of engineers may be one step closer to cleaning up heavily contaminated industrial wastewater streams. Researchers from the School of Chemical and Biomolecular Engineering developed an electrochemical oxidation process with the aim of cleaning up complex wastewater that contained a toxic…
“#A quarter of the world’s lowland population depends critically on mountain water resources” Mountains are important “Water Towers”. This is the Rosegbach River in Switzerland, part of the Danube river basin where a third of the 46 million people living downstream strongly depend on water resources from mountain areas. Credit: D. Viviroli Global water consumption…
