Arctic sea ice extent shrank to 1.6 million square miles earlier this month — tying 2016 with 2007 as the second lowest sea ice minimum since satellite records began. The lowest year remains 2012. The new measurements follow a decades-long trend of declining sea ice extent in the Arctic as global temperatures rise. 

When you go out for sushi or visit a seafood restaurant, how sure can you be that you’re really getting what you’ve ordered? Last week, Oceana released some shocking findings: Around the world, an average of one in five samples of seafood is mislabeled.The report examined 25,000 samples worldwide and reviewed more than 200 published studies from 55 different countries.…

Marine ecosystems are responsible for about half of global annual primary production and more than one billion people rely on fish as their primary protein source. Latest studies show that enormous warm water bubbles in the ocean are having a noticeable impact on ecosystems. How should we interpret these changes?

This is an issue of global concern. Climate change, urbanization, and resource depletion (more mouths to feed, burn wood in stoves for, graze more cattle for) is still happening at a fast an alarming clip, influencing our planet’s ability to store CO2 emissions, and protect diversity. 

Bayer's $66 billion takeover of Monsanto represents another big click on the ratchet of corporate power over farming and food, writes Colin Todhunter. With the 'big six' of global agribusiness now set to turn into the 'even bigger three', farmers and consumers are facing more GMOs and pesticides, less choice, and deeper price gouging. Agroecology…

After five years of research and development, Virgin Atlantic and one of its clean-technology partners, Illinois-based LanzaTech, developed a source of jet fuel made of waste gases from steel mills. According to the companies, this new source of jet fuel passed extensive tests that both delivered on performance and promise to result in carbon emissions savings of 65 percent…

A new energy market analysis shows the average cost of electricity from renewables is already lower than from fossil fuels, writes Alex Kirby. And as renewables eat deeper into the 'market share' of coal and gas power plants, so the entire economics of fossil fuel power generation will unravel.The cheapest way of generating energy today…

This year the extent of summer sea ice in the Arctic is heading towards being the second lowest on record. The Arctic sea ice minimum marks the day – typically in mid-September – when sea ice reaches its smallest extent at the end of the summer melt season. British Antarctic Survey sea-ice scientist, Dr Jeremy…

Research led by the National Centre of Earth Observation at the University of Leicester is going to new heights in the atmosphere to get a better handle on methane emitted from wetlands in the Amazon.Using small aircraft flying in an upward spiral and collecting samples of the air, the team has measured the levels of…

A new University of Washington study, with funding and satellite data from NASA and other agencies, finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper, to…
