En virtud del Acuerdo de París de 2015, las naciones se comprometieron a elevar la temperatura global promedio en menos de 2 ° C por encima de los niveles preindustriales y a tomar medidas para reducir esa elevación a 1,5 ° C. Para alcanzar esos objetivos, no solo debemos detener el aumento de nuestras emisiones de gases de efecto invernadero, también debemos extraer grandes cantidades de dióxido de carbono (CO2) de la atmósfera.
Think, for a moment, about the last time you were out in nature. Were you in a city park? At a campground? On the beach? In the mountains?
Now consider: What was this place like in your parents’ time? Your grandparents’? In many cases, the parks, beaches and campgrounds of today are surrounded by more development, or are themselves more developed, than they were decades ago.
As intense rain storms moved into Jeddah, Saudi Arabia on Nov. 21, NASA’s Global Precipitation Measurement Mission or GPM core satellite analyzed the severe storms.
More than 23.5 million Americans suffer from autoimmune diseases like rheumatoid arthritis, scleroderma and lupus, in which an overzealous immune response leads to pain, inflammation, skin disorders and other chronic health problems. The conditions are so common that three of the top-five selling drugs in the United States aim to ease their symptoms. But no cure exists, and treatments are expensive and come with side effects.
Now CU Boulder researchers have developed a potent, drug-like compound that could someday revolutionize treatment of such diseases by inhibiting a protein instrumental in prompting the body to start attacking its own tissue.
Satellites are keeping an eye on the U.S. and NOAA’s GOES East satellite showed two storm systems for pre-Thanksgiving travelers on Wednesday, Nov. 22, 2017. One system was exiting the northeastern U.S. while the other was affecting the Pacific Northwest.
Power stored in electric cars could be sent back to the grid – thereby supporting the grid and acting as a potential storage for clean energy – but it will only be economically viable if we upgrade the system first. In a new paper in Energy Policy, two scientists show how their seemingly contradictory findings actually point to the same outcome and recommendations: that pumping energy back into the grid using today’s technology can damage car batteries, but with improvements in the system it has the potential to provide valuable clean energy – and improve battery life in the process.
