Butter Is Toast
Margarine has a significantly lower environmental impact than butter in four important areas: global warming potential (i.e., carbon footprint), eutrophication potential, acidification potential, and land impact
Turkey litter could partially replace coal as fuel
Poultry farms generate up to 938 megatons of bird litter each year, but now researchers have identified an efficient way to repurpose that waste as fuel.
What if the world phased out meat consumption over 15 years? The numbers are stunning—and instructive.
Such a bold transition would cut anthropogenic emissions by 68% by century-end, and get us more than halfway to achieving the goals of the Paris Climate Agreement.
What if the whole world went solar?
Widespread installation of solar panels would have cascading effects on the climate
Wilderness areas could reduce extinction risks by more than half
For all its philosophical troubles, wilderness—big, contiguous places with minimal human footprints—is still enormously important to prevent extinctions.
Why does climate denial still receive more news coverage than climate action?
It's not always clear who and what drives the public discourse about climate change
Farmers wiped out habitat to reduce disease from wildlife. For birds, their efforts backfired.
New study finds that birds caught on California farms with nearby wildlands had less problem bacteria than those at more manicured farms.
Seeing sharks in a new dimension
Few members of the animal kingdom are quite so maligned as sharks. And yet: might sharks have friends?
Flying is even worse for air quality than for climate
Researchers suggest the best ways to reduce the societal impact of aviation's climate and pollution emissions
The best-case climate change scenario could wind up being twice as bad as we think
When computer climate models run farther into the future, they underestimate likely warming by a factor of two. Therefore, they underestimate eventual sea level rise as well.
