The irregular swings between warm and wet "El Niño" conditions in the equatorial Pacific and the cold and dry "La Niña" state influence weather con...

Ideas, Inventions And Innovations Magnetic Waves Explain Mystery Of Sun’s Outer Layer A theory as to why the Sun's outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for the first time by scientists at UCL and the Italian Space Agency. The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

 E-Mail The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades. One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun's plasma into different components, so that only the ion particles are transported into the corona, while leaving neutral particles behind (thus leading to a build-up of elements such as iron, silicon and magnesium in the outer atmosphere). Now, in a new study published in The Astrophysical...

2) in the atmosphere reach levels 50 percent higher than those before the Industrial Revolution. The new forecast by the UK Met Office says that the concentrations of CO 2 will be around 2.29 parts per million (ppm) higher in 2021 than in 2020 at the Mauna Loa Observatory in Hawaii. This means atmospheric concentrations will exceed 417 ppm from April to June and be more than 50 percent higher than the level of 278 ppm seen in the late 18th century before the Industrial Revolution.  The last time global carbon dioxide levels were consistently above 400 ppm was around 4 million years ago...

Four tropical cyclones in the Pacific Ocean, Sept. 2015. (Photo credit: NASA/NOAA GOES Project.) Global warming will intensify landfalling tropical cyclones of a category three or higher in the Indian and Pacific Oceans, while suppressing the formation of weaker events. In Hawaiʻi, model simulations show a doubling of the risk of landfalling tropical cyclones, if CO2 concentrations double. That’s according to a study published in Malte Stuecker, assistant professor of oceanography in the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology ( SOEST).
