In perhaps the final major act of conservation of his administration, President Barack Obama on Wednesday designated 1.35 million acres in southeast Utah and 300,000 acres in Nevada as two new national monuments.
Madrid is drawing up lans to plant gardens on the rooftop of the city’s buses and bus stops.
The authorities in the Spanish capital have come up with the proposals as a novel way of tackling CO2 emissions, The Local reported. The gardens are also intended to soak up heat, noise and pollution.
For years cities have encouraged residents to install green roofs—gardens that turn barren tar and asphalt roofs into verdant oases. The added foliage helps to keep buildings cool in the summertime and warm in the winter; it can also ease sewers by absorbing rainfall. But not just the hardscape benefits from these lush areas—so do some urban dwellers: bats.
Each year, around 88 million tons of food is discarded in the EU. This is something that researchers wants to do something about. They are now giving companies in the food supply chain specific tools that can reduce both food waste and the environmental impact of food transport.
Thierry Lepercq, head of research, technology and innovation at the French energy company Engie SA, said in an interview at Bloomberg that he sees a potential for the cost of solar electricity to fall below $10-megawatt hour (1¢/kWh) in the sunniest climates by 2025. Lepercq believes “solar, battery storage, electrical and hydrogen vehicles, and connected devices are in a ‘J’ curve (of upward growth potential).” One consequence of this new energy economy is that, “the price (of oil) could drop to $10 if markets anticipate a significant fall in demand.”
Sweden has generated more energy from wind power than it ever has before.
Nearly 5.7 million kWh of wind power was generated as the country harvested the effects of “Storm Urd” and intense weather across the south of the country. That smashed through the previous record, set almost exactly a year ago, beating it by more than half a million kWh.
Costa Rica completes 2016 without having to burn a single fossil fuel for more than 250 days. 98.2 percent of Costa Rica’s electricity came from renewable sources in 2016.

Geoengineering is one of those things that sounds like maybe a good idea on paper but could also go horribly, apocalyptically wrong. But if the prospect of plunging Earth’s weather systems into chaos isn’t enough to convince scientists we need to tread very cautiously with the ultimate global warming tech-fix, perhaps this will: geoengineering could be a disaster for science.
A huge area of volcanic activity near heavily populated Naples, Italy, is reaching a critical point and scientists think it could erupt. The 12-kilometer (7.46 miles) caldera or volcanic cauldron hasn’t erupted for nearly 500 years, but scientists say the seismic monster is reawakening.

Old Faithful in Wyoming is one of Yellowstone National Park’s most famous geysers, regularly spewing out huge jets of boiling water and steam every 74 minutes on average.
But this week, the geyser appears to be erupting snow, due to unseasonably cold weather in the region.
Our future crops will face threats not only from climate change, but also from the massive expansion of cities, a new study warns. By 2030, it’s estimated that urban areas will triple in size, expanding into cropland and undermining the productivity of agricultural systems that are already stressed by rising populations and climate change.
A tiny plant is providing big clues about how human development is driving the evolution of living organisms. New research from the University of Toronto Mississauga reveals the first evidence that common white clover changes genetically to adapt to urban environments.
Nations worldwide have agreed to limit carbon dioxide emissions in hopes of preventing global warming from surpassing 2 degrees Celsius by 2100. But countries will not manage to meet their goals at the rate they’re going. To limit warming, nations will also likely need to physically remove carbon from the atmosphere. And to do that, they will have to deploy “negative emissions technology”—techniques that scrub CO2 out of the air.
Temperatures at the North Pole could be up to 20 degrees higher than average this Christmas Eve, in what scientists say is a record-breaking heatwave.
Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation.
Giant piles of black manure towering over cornfields, while rancid-smelling effluent from thousands of cows spills onto the land—this is the price of a glass of milk in China today.
Large-scale dairy farms have boomed in the Asian giant, as its near 1.4 billion consumers overcame centuries of cultural reluctance to embrace the white fluid.
