Electric vehicle use in Norway accelerating

Electric vehicle use in Norway accelerating

Business
March 22 (UPI) -- The number of electric vehicles registered by Norwegian drivers has increased by more than 40 percent from the previous year, the government said.Statistics Norway, the government's record-keeping agency, reported there were 142,490 total electric cars registered in the country at the beginning of the year, up more than 40 percent from one year ago. Passenger vehicles made up 97 percent of that total.Data for members of the European Union show the market share of hybrid and battery-powered electric vehicles make up about 1 percent of the total market, though trends are accelerating as consumer interest grows.The Norwegian government said electric vehicles make up about 5 percent of the passenger fleet, compared with 3.7 percent at the end of 2016."The increase seems set t...
Satellites show warming is accelerating sea level rise

Satellites show warming is accelerating sea level rise

Technology
Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet (61 centimeters) higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences. Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports. "It's a big deal" because the projected sea level ...
Black carbon persists across the planet, accelerating glacial melt

Black carbon persists across the planet, accelerating glacial melt

Science
June 30 (UPI) -- New research shows black carbon deposits vary across the planet, but persist in a variety of glacial ecosystems.Black carbon is the soot-like particulate matter released by the combustion of fossil fuels, biofuel and biomass -- through man-made processes, like the burning of coal, and natural means, like wildfires.Climate scientists are interested in black carbon because deposits among snow and glaciers affect melting rates. Black soot absorbs more energy than white snow and ice.Scientists at the University of Colorado, Boulder recently conducted a global survey of black carbon deposits. Molecular analysis of the deposits helped scientists trace the sources of black carbon deposits and measure changes in deposition rates.On Greenland's ice sheet, researchers found evidence...
