Queen Anne's County passes law to protect dogs from extreme weather
Recently Queen Anne's County passed a law making it illegal to leave your dog outside in extreme weather. The new law requires any dog to be brought inside a home, building, or shelter within 30 minutes of the onset of extreme weather conditions that …

BRUSSELS (Reuters) – EU negotiators on Thursday agreed to phase out the use of palm oil in transport fuels from 2030, setting up a clash with producer countries such as Malaysia and Indonesia. A text of the deal, seen by Reuters, leaves the wording on …
Scientists in the U.S. and Europe reported this week (June 13, 2018) on what they said what the most robust assessment to date of ice loss in Antarctica and its contribution to global sea level rise. The assessment – funded by NASA and the European Space Agency (ESA) – combines 24 satellite surveys of Antarctica and involves 80 scientists from 42 international organizations. Its results are that ice losses from Antarctica are moving at a faster rate now, with the rate tripling since 2012. The result has been that global sea levels have risen by 0.12 inch (3 millimeters) in that timeframe alone. A statement from NASA said:
According to the study, ice losses from Antarctica are causing sea levels to rise faster today than at any time in the past 25 years.
The peer-reviewed journal Nature published the recent results of the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) on June 13, 2018.
Assessment team co-lead Erik Ivins at NASA’s Jet Propulsion Laboratory in Pasadena, California, said:
This is the most robust study of the ice mass balance of Antarctica to date. It covers a longer period than our 2012 IMBIE study, has a larger pool of participants and incorporates refinements in our observing capability and an improved ability to assess uncertainties.
The team looked at the mass balance of the Antarctic ice sheet from 1992 to 2017 and found ice losses from Antarctica raised global sea levels by 0.3 inches (7.6 millimeters), with a sharp uptick in ice loss in recent years. They attribute the threefold increase in ice loss from the continent since 2012 to a combination of increased rates of ice melt in West Antarctica and the Antarctic Peninsula, and reduced growth of the East Antarctic ice sheet.
Prior to 2012, ice was lost at a steady rate of about 83.8 billion tons (76 billion metric tonnes) per year, contributing about 0.008 inches (0.2 millimeters) a year to sea level rise. Since 2012, the amount of ice loss per year has tripled to 241.4 billion tons (219 billion metric tonnes) – equivalent to about 0.02 inches per year (0.6 millimeters) of sea level rise.
West Antarctica experienced the greatest recent change, with ice loss rising from 58.4 billion tons (53 billion metric tonnes) per year in the 1990s, to 175.3 billion tons (159 billion metric tonnes) a year since 2012. Most of this loss came from the huge Pine Island and Thwaites glaciers, which are retreating rapidly due to ocean-induced melting.
At the northern tip of the continent, ice-shelf collapse at the Antarctic Peninsula has driven an increase of 27.6 billion tons (25 billion metric tonnes) in ice loss per year since the early 2000s. Meanwhile, the team found the East Antarctic ice sheet has remained relatively balanced during the past 25 years, gaining an average of 5.5 billion tons (5 billion metric tonnes) of ice per year.
Antarctica’s potential contribution to global sea level rise from its land-held ice is almost 7.5 times greater than all other sources of land-held ice in the world combined. The continent stores enough frozen water to raise global sea levels by 190 feet (58 meters), if it were to melt entirely.
Knowing how much ice it’s losing is key to understanding the impacts of climate change now and its pace in the future.
HONOLULU — Officials from a Big Island astronomical observatory say an oil leak was discovered in the hydraulic system supporting one of its telescopes. Officials from the W.M. Keck Observatory notified the state Department of Health of the leak from the …
The Hinckley Dasher is the first all electric luxury yacht. It is smooth, svelte and ‘spensive and comes with batteries supplied by BMW.
It was with a mixture of anxiety, and excitement, that I realised, about three years ago, that used EVs, were now available to buy, at an affordable price, and, which would serve my purposes. At the time, I was not totally sure that an EV would really suit me, and be practical, so, I was reticent to spend much money in buying one
