I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Scientists on Arctic mission make unplanned detour to pole” Credit: CC0 Public Domain A German icebreaker carrying scientists on a year-long international expedition in the high Arctic has reached the North Pole, after making an unplanned detour because of lighter-than-usual sea ice conditions. Expedition leader Markus Rex said Wednesday the RV Polarstern was able to…
“#The tropics are expanding, and climate change is the primary culprit” Credit: Unsplash/CC0 Public Domain Earth’s tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research. The tropics wrap around Earth’s middle like a warm, wet belt. This part of the globe gets the most direct…
“#Research team is first to observe new equatorial wind patterns in Antarctica” Lidar shooting into the Antarctic night sky, Arrival Heights Observatory. Credit: Danny Hampton, Ian Geraghty, Zimu Li A CIRES-led team has uncovered a critical connection between winds at Earth’s equator and atmospheric waves 6,000 miles away at the South Pole. The team has…
“#Study finds land surface conditions can affect mesoscale convective systems while they are on the move” Intense dust storms, such as this haboob in Mali in August 2006, proceed torrential rain. Credit: Françoise GUICHARD / Laurent KERGOAT / CNRS Photo Library Ground-breaking scientific research will make it easier to predict the path of some of…
“#Methane emissions from northern lakes are higher during the daytime” The contribution of northern lakes to global methane emissions is 15 per cent lower than previously estimated. Credit: Monica Westman Methane fluxes from lakes are considerably higher during the day than the night, according to a study conducted by LiU researchers. Consequently, the research group…
“#Climate study looks at humans’ exposure to extreme temperatures during 21st century” Credit: CC0 Public Domain Denver is known for its relatively mild climate and its four distinct seasons. It’s also known for its temperature fluctuations over the course of a day or even hours. But what does that mean for the city’s residents—and for…
“#Farmers help grow water plan” The heavily agricultural La Vi River Basin in Vietnam was the focus of the study. Credit: Flinders University Overallocation of surface water for growing food crops is shifting agriculture and other industry to use groundwater—which is much more difficult to measure and monitor. Using local producer knowledge as ‘soft data’…
“#More than half of world’s oceans already being affected by climate change” Credit: CC0 Public Domain More than 50% of the world’s oceans could already be affected by climate change, with this figure rising as high as 80% over the coming decades, a new study has shown. Scientists used climate models and observations in deeper…
“#Reconstructing global climate through Earth’s history” Sea surface temperatures in shallow, semi-enclosed seas today are warmer than they should be for their locations. Many paleotemperature data come from settings like these, raising the possibility that ancient temperatures suggest a warmer ancient Earth. Credit: Syracuse University A key component when forecasting what the Earth’s climate might…
“#Restoring degraded tropical forests generates big carbon gains” Dipterocarp seeds are collected in primary forest and grown in nurseries to provide sufficient planting material for large-scale restoration efforts. Credit: Michael O’Brien / SEARRP More than half of the world’s aboveground carbon is stored in tropical forests, the degradation of which poses a direct threat to…
