World deforestation: we're losing a forest the size of NYC every 2 days!
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.

Monsanto and Bayer: food and agriculture just took a turn for the worst
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…

Virgin Atlantic: Emissions from Steel Mills Could Fuel Airplanes
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…

Renewables have the economic advantage over fossil fuels
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…

Arctic sea ice heading towards second lowest on record
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…

All polar bears across the Arctic face shorter sea ice season
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…

Experts anticipate significant continued reductions in wind energy costs
Technology advancements are expected to continue to drive down the cost of wind energy, according to a survey of the world's foremost wind power experts led by Lawrence Berkeley National Laboratory (Berkeley Lab). Experts anticipate cost reductions of 24%-30% by 2030 and 35%-41% by 2050, under a median or 'best guess' scenario, driven by bigger…
