If there are no woods where they live, where do they…
Scientists have long wondered whether polar bears are able to enter a physiological state resembling hibernation in response to food shortages, an adaptation some researchers have speculated could protect the species even as their hunting grounds melt away. Today, we have an answer—though it’s not the one we’ve been hoping for.

The bears were outfitted with fitness trackers 😉
There’s a lot more to consider when looking at climate change in future models than meets the eye. Yes carbon emissions from the burning of fossil fuels plays a part, but so can the simple changes in the agricultural practices that feed a growing world. And a new study published this week in the journal Nature reveals that levels of carbon dioxide will likely be on the rise, at least in the Northern Hemisphere, as summer heat and the tail-end of the growing season will spark major crop plants to release CO2 in parts of the growing season.
While the team of researchers from Boston University found that corn, soybeans, wheat and rice are the four leading crops that account for maximum CO2 release in the atmosphere of the Northern Hemisphere, the likely culprit will be corn. And how much could a corn plant affect our planet, you might ask yourself? The researchers revealed that agricultural production is likely to account for up to a 25% surge in the seasonal carbon cycle – far more than what humans are capable of.

In the U.S., climate change is likely to increase average daily temperatures and the frequency of heat waves. Dairy cows are particularly sensitive to heat stress and, according to a new USDA study, by 2030, milk production will have lowered to the point that additional economic costs will exceed $100 million per year.

That’s for the US. It might mean that Canada becomes a more viable location for dairy cattle, and Canada has space to spare… Maybe it’d just be a matter of shifting the source?
