2 August 2018 (NOAA) – It’s official: 2017 was the third-warmest year on record for the globe, trailing 2016 and 2015, according to the 28th annual State of the Climate report. The planet also experienced record-high greenhouse gas concentrations as well as rises in sea level. The annual checkup for the planet, led by scientists […]
6 August 2018 (Stockholm Resilience Centre) – An international team of scientists has published a study in Proceedings of the National Academy of Sciences (PNAS) showing that even if the carbon emission reductions called for in the Paris Agreement are met, there is a risk of Earth entering what the scientists call “Hothouse Earth” conditions.A […]
By Marcie Grabowski 1 August 2018 (UH News) – Several greenhouse gases are emitted as common plastics degrade in the environment, according to researchers from the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST).Mass production of plastics started nearly 70 years ago, and the production rate is expected to […]
By Adam Voiland 19 July 2018 (NASA) – Astronaut and scientist Piers Sellers is no longer with us, but his words still resonate.A posthumous plea from Sellers arrived in July 2018 in the form of an article in PNAS. The topic was one that he cared deeply about: building a better space-based system for observing […]
By Anthony J. Marchese and Dan Zimmerle 2 July 2018(The Conversation) – Natural gas is displacing coal, which could help fight climate change because burning it produces fewer carbon emissions. But producing and transporting natural gas releases methane, a greenhouse gas that also contributes to climate change. How big is the methane problem?For the past […]
By Spencer Dale 13 June 2018(BP) – At first blush, some of last year’s data might seem a little disappointing. Growth in overall energy demand is up; gains in energy intensity are down. Coal consumption grew for the first time in four years. And, perhaps most striking of all, carbon emissions are up after three […]
30 May 2018 (NOAA) – NOAA’s Annual Greenhouse Gas Index (AGGI), which tracks the warming influence of long-lived greenhouse gases, has increased by 41 percent from 1990 to 2017, up 1 percent from 2016 — with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists. [cf. NOAA’s greenhouse gas index […]
By Paul Voosen 9 May 2018 (Science) – You can’t manage what you don’t measure. The adage is especially relevant for climate-warming greenhouse gases, which are crucial to manage—and challenging to measure. In recent years, though, satellite and aircraft instruments have begun monitoring carbon dioxide and methane remotely, and NASA’s Carbon Monitoring System (CMS), a […]
By Scott Schrage 19 April 2018 (University of Nebraska–Lincoln) – Homo sapiens, Neanderthals and other recent human relatives may have begun hunting large mammal species down to size — by way of extinction — at least 90,000 years earlier than previously thought, says a new study published in the journal Science.Elephant-dwarfing wooly mammoths, elephant-sized ground […]
15 February 2018 (EDF) – Methane emissions from Pennsylvania’s oil and gas sites may be more than five times higher than what oil and gas companies report to the Pennsylvania Department of Environmental Protection (DEP), according to a new analysis from Environmental Defense Fund.Methane is both a powerful climate pollutant and the primary ingredient of […]
