And yet, the climate story of this past decade has been one of slow but steady progress. Global CO2 emissions have flattened, and countries representing 88% of global emissions have adopted or announced plans to get to net zero in the...
Honey bee life spans are 50% shorter today than they were 50 years ago
A new study by University of Maryland entomologists shows that the lifespan for individual honey bees kept in a controlled, laboratory environment is 50% shorter than it was in the 1970s. When scientists modeled the effect of today's shorter lifespans, the results corresponded with the increased colony loss and reduced honey production trends seen by U.S. beekeepers in recent decades.
Subarctic boreal forest, vital for the planet, is at risk
It burns, it drifts, it falls victim to insects. And it's shrinking.
In Canada's boreal forest, one man works to save caribou
Even though he lives in the middle of Canada's boreal forest, Jean-Luc Kanape can sometimes go weeks without seeing a single caribou. But for as long as he can remember, the animals have been part of his life.
