The U.S. now has two coal-burning power plants that avoid dumping carbon dioxide into the air. Petra Nova in Texas and Kemper in Mississippi use technology to stop CO2 in the smokestack and before combustion, respectively. Unfortunately, that makes two out of more than 400 coal-fired power plants in the U.S., the rest of which collectively pour 1.4 billion metric tons of the colorless, odorless greenhouse gas into the atmosphere each year. Even Kemper and Petra Nova do not capture all of the CO2 from the coal they burn, and the captured CO2 is used to scour more oil out of the ground, which is then burned, adding yet more CO2 to the atmosphere. The carbon conundrum grows more complex — and dangerous — with each passing year.
Over the past few years, a large fracture has grown across a large floating ice shelf on the Antarctic Peninsula. The world is watching the ice shelf, now poised to break off an iceberg the size of Delaware into the ocean.
It’s not a new phenomenon; this “thumb” of Antarctica, which juts out into the stormy Southern Ocean, has lost more than 28,000 square kilometers of floating ice — almost as large as Massachusetts — over the past half-century. This has included the complete disintegration of four ice shelves, the floating extensions of glaciers.
During periods of greater Atlantic hurricane activity, a protective barrier of vertical wind shear and cooler ocean temperatures forms along the U.S. East Coast, weakening storms as they approach land, according to a new study by NCEI scientist, Jim Kossin. In his paper, “Hurricane Intensification along United States Coast Suppressed during Active Hurricane Periods (link is external),” published in Nature, Kossin identifies this “buffer zone” and describes its relationship with both active and inactive periods of Atlantic hurricane activity.
As scientists work to predict how climate change may affect hurricanes, droughts, floods, blizzards and other severe weather, there's one area that's been overlooked: mild weather. But no more.
NOAA and Princeton University scientists have produced the first global analysis of how climate change may affect the frequency and location of mild weather - days that are perfect for an outdoor wedding, baseball, fishing, boating, hiking or a picnic. Scientists defined "mild" weather as temperatures between 64 and 86 degrees F, with less than a half inch of rain and dew points below 68 degrees F, indicative of low humidity.
A study led by scientists at the Translational Genomics Research Institute (TGen) has identified "a potent inhibitory compound" in the elusive hunt for an improved treatment against glioblastoma, the most common and deadly type of adult brain cancer.Aurintricarboxylic Acid (ATA) is a chemical compound that in laboratory tests was shown to block the chemical cascade that otherwise allows glioblastoma cells to invade normal brain tissue and resist both chemo and radiation therapy, according to a TGen-led report published today in the scientific journal Oncotarget.
Watching cars zoom around and around an oval track isn't Jesse Hensley's idea of a good time. Making them run on biofuel would be.
China has canceled plans for more than 100 new coal-fired power plants, including several that were already under construction, according to news reports. The power stations, with an estimated price tag of $62 billion, would have had an electricity-generating capacity of more than 100 gigawatts, spread across several provinces.
With winter upon us in full force, outdoor temperatures are plummeting. But inside an intense tornado, it’s always chilly — no matter the time of year. A new study from Concordia proves why that’s the case.
In an article forthcoming in the Journal of Aircraft of the American Institute of Aeronautics and Astronautics, mechanical engineering professor Georgios Vatistas looks into the case of a violent tornado that touched down in 1955 in Scottsbluff, Nebraska.
Afocus on policies to conserve tropical forests for their carbon storage value may imperil some of the world’s most biologically rich tropical forests.
With a hybrid crop called Salish Blue, scientists at Washington State University have combined wheat and wheatgrass in a new species with the potential to help Pacific Northwest farmers and the environment.
