Whenever I visit the Sahara I am struck by how sunny and hot it is and how clear the sky can be. Aside from a few oases there is little vegetation, and most of the world’s largest desert is covered with rocks, sand and sand dunes. The Saharan sun is powerful enough to provide Earth with significant solar energy.
Only seven months after NASA's Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world's largest island, an OMG crew is back in Greenland to collect more data. With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland's melting glaciers affects them. All that data has answered a lot of existing questions — and it's raised plenty of new ones.
A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers' undersides in calculating how fast global sea levels will rise in response to climate change.
Is your morning coffee an espresso or a skinny latte? Is it from a darkly roasted French or Italian blend? If it’s a high quality brew, it’s almost certainly made with beans from the Arabica species (Coffea arabica), which is known for its finer flavours. Examples would be Javan coffees, Ethiopian sidamo, and the expensive Jamaican blue mountain.
The winter holidays are a busy time for many businesses, including retail stores, grocers, liquor stores – and dry cleaners. People pull out special-occasion clothes made of silk, satin or other fabrics that don’t launder well in soap and water. Then there are all those specialty items, from stained tablecloths to ugly holiday sweaters.
Wageningen University & Research is working on a road-map to future-proof crops as part of EU-project CropBooster-P. Future crop yields will increase with optimal use of water and minerals. In addition to that nutritional value and crop quality are high on the list of targets. To feed a future population of 10 billion people and alleviate climate change these new crops need to eventually double the total world wilde food production. The great news that has been scientifically proven to be possible.
Not only is air pollution bad for our lungs and heart, it turns out it could actually be making us less intelligent, too. A recent study found that in elderly people living in China, long-term exposure to air pollution may hinder cognitive performance (things like our ability to pay attention, to recall past knowledge and generate new information) in verbal and maths tests. As people age, the link between air pollution and their mental decline becomes stronger. The study also found men and less educated people were especially at risk, though the reason why is currently unknown.
Much like Oxford English Dictionary’s “Word of the Year” competition, the international statistic is meant to capture the zeitgeist of this year. The judging panel accepted nominations from the statistical community and the public at large for a statistic they feel shines a light on today’s most pressing issues.
