The world’s biggest meat and dairy operations combined pump more greenhouse gas into Earth’s warming atmosphere than any one of the largest fossil-fuel giants.
A quarter of the impact of meat production comes from the pet-food industry. Has the time come to change what we feed our dogs and cats?
The axolotl, or Ambystoma mexicanum, is the ultimate survivalist: When an axolotl loses a leg, tail, or a bit of its heart, the body part regrows and nary a scar remains. But the hardy creature is on the brink of extinction.
We humans are all too good at putting carbon dioxide into the atmosphere. Can we come up with a way to vacuum it out?
A zero-emissions target may seem inflexible, but it’s actually much more actionable than a variable and uncertain emissions budget. It is relatively simple for each country to set a target date to reach zero emissions, based on, say, how wealthy it is. Then, each greenhouse-gas emitting entity in the country can set its own goal to reach zero emissions and governments can lay out effective policies to help emitters get there by the target date.
There are certain axioms about the natural world we learn as children. The sea is salty. Plants grow toward light. Bears hibernate in winter.
But as climate change leads to warmer winters, later falls and earlier springs — which can disrupt both food supplies and biological rhythms — American black bears are changing their hibernation routines, scientists say. In some cases, bears are not hibernating at all, staying awake all winter. In others, bears are waking from their slumber too early.
Central bankers have been dubbed “masters of the universe” for the tools and powers they have acquired since the financial crisis. Some of them now want to play a more active role in the fight against climate change.
The Environmental Defense Fund on Wednesday announced a plan to build and launch a satellite that will measure major global sources of methane, including 50 oil-and-gas regions that make up about 80 percent of production, as well as feedlots and landfills.
The world’s greatest forests could lose more than half of their plant species by the end of the century unless nations ramp up efforts to tackle climate change, according to a new report on the impacts of global warming on biodiversity hotspots.
Every summer for the last eight years, people who live in the Swiss Alps have been wrapping a beloved glacier in blankets.
